Sustaining soil fertility is essential to the prosperity of many households in the mid-hills of Nepal, but there are concerns that the breakdown of the traditional linkages between forest, livestock, and cropping systems is adversely affecting fertility. This study used triangulated data from surveys of households, discussion groups, and key informants in 16 wards in eastern and western Nepal to determine the existing practices for soil fertility management, the extent of such practices, and the (...) perception of the direction of changes in soil fertility. The two principal practices for maintaining soil fertility were the application of farmyard manure (FYM) and of chemical fertilizer (mainly urea and diammonium phosphate). Green manuring, in-situ manuring, slicing terrace risers, and burning plant residues are rarely practiced. FYM usage was variable with more generally applied to khet land (average 6053 kg fresh weight manure ha−1) than to bari land (average 4185 kg fresh weight manure ha−1) with manure from goats and poultry preferred above that from cows and buffaloes. Almost all households (98%) apply urea to khet land and 87% to bari land, with 45% applying diammonium phosphate to both types of land. Application rates and timings of applications varied considerably both within and between wards suggesting poor knowledge transfer between the research and farming communities. The benefits of chemical fertilizers in terms of ease of application and transportation in comparison with FYM, were perceived to outweigh the widely reported detrimental hardening of soil associated with their continued usage. Among key informants, FYM applied in conjunction with chemical fertilizer was the most popular amendment, with FYM alone preferred more than chemical fertilizer alone – probably because of the latter’s long-term detrimental effects. Key informant and householder surveys differed in their perception of fertility changes in the last decade probably because of differences in age and site-specific knowledge. All key informants felt that fertility had declined but among households, only about 40% perceived a decline with the remainder about evenly divided between no change and an increase. Householders with small landholdings (< 0.5 ha) were more likely to perceive increasing soil fertility while those with larger landholdings (> 2 ha) were more likely to perceive declining fertility. Perceived changes in soil fertility were not related to food self-sufficiency. The reasons for the slow spread of new technologies within wards and the poor understanding of optimal use of chemical fertilizers in conjunction with improved quality FYM may repay further investigation in terms of sustaining soil fertility in this region.

Donors, scientists and farmers all benefit when research and development projects have high impact. However, potential benefits are sometimes not realized. Our objective in this study is to determine why resource-poor farmers in Togo (declined to) adopt recommended practices that were promoted through a multi-organizational project on soil fertility management. We examine the processes and outcomes related to the adoption process. The project was undertaken in three villages in the Central Region of Togo in West Africa. The (...) development and research processes that took place during the implementation of the project were critically analyzed using a conceptual framework that may be useful for improving the impact of future participatory projects. At the macro level, opportunities for innovation were not deliberately explored with participating farmers and other village members; consequently “pre-analytical choices” made during the planning phase resulted in practices that resource-poor farmers were, for a variety of reasons, unable or unwilling to adopt. From the outset, donors and scientists focused on soil fertility management, but failed to take into account the wider economic context within which soil fertility management took place. This was a major obstacle to the subsequent adoption of recommended management strategies. Scientists and donor partners measured the success of the Project in terms of crop productivity, but farmers’ choices were influenced by a complex mix of socio-economic, political and technical factors. We also illustrate the importance of selecting appropriate categories of farmers for a particular experiment. We conclude that for participatory research and development projects to be successful, it is not enough to develop technologies that “work” in a technical sense. In order to be scaled up and widely implemented, such technologies must also meet a variety of needs of resource-poor farmers and be acceptable from a socio-cultural point of view. (shrink)

Colonists, unlike indigenous peoples, are often assumed tohave little knowledge of their environment. However, their perceptions of the environment and their knowledgeof natural resource systems have a significant impact on their farming practices. Farmers in the frontier regionof Marabá, Eastern Amazonia, understand nutrient cycling and the links between different components in farmingsystems. Diagrams drawn by farmers show very diversified systems, and farmers' knowledge of soilcharacteristics, including sub-surface features, and distribution in their localities is very detailed in comparison to pedologicalclassifications. However, (...) knowledge about nutrient cycling is very uneven, even between farmers from the same area.Generally, farmers were found to have very detailed knowledge of environmental resources, but very patchyknowledge of processes and functions underlying systems, and this conforms to evolutionary models of ecologicalknowledge. Perceptions of change in soil fertility are related to the length of settlement, and are closelylinked to the presence of forest. Overall, the majority of farmers believe they will not be able to sustain cropping in thefuture, and as forest and fallow become scarce the most feasible option will be for them to move to other areas.Farmers are more optimistic about pasture, which is viewed as a more stable system, with the key to long-termsustainability being weed control. These findings imply that a high degree of information sharing between farmers andscientists is required to establish resource management strategies and social institutions to supportsustainable development strategies at the frontier.

According to literature,insecure land tenure biases against soilconservation on farmland. However, there islittle evidence to test whether farmers need toown their land to conserve it, or if long-termleases are adequate. One way to infer whetheror not different land tenure arrangementspromote long-term management is throughanalyzing the types of crops planted on fieldswith different land tenure arrangements.Perennials, forage legumes, grasslands, andgrain are all important parts of sustainablecrop rotation in southwest British Columbia butprovide little cash return in the year they areplanted. Annual (...) crops provide a high cashreturn but create soil conservation problems ifthey are planted too often. A comparison offields with different land tenures showed thatfarmers who own their land plant moreperennials, grain, and forage legumes thanfarmers who rent fields. Few differences wereobserved on fields with different leaselengths. This study leads to three overallconclusions. First, although results confirmthe literature, and insecure land tenure is areal obstacle to long-term soil conservation,it is not possible to assume that long-termleases will substitute for land ownership.Second, it is possible to use relativelyeasy-to-gather data on crop history to assessthe impact of tenure on farming. Third,intervening variables, in this case a programthat pays farmers to plant grasslands,over-rides the effect of insecure land tenureand creates incentives for owner-operators andtenant farmers alike to use crop managementthat protects soil fertility in the longterm.

A critical comparative analysis of howfarmers and scientists classify and manage soilsreveals fundamental differences as well assimilarities. In the past, the study of local soilknowledge has been predominantly targeted atdocumenting how farmers classified their soils incontrast to understanding how such classificatoryknowledge was made use of in actually managing soilsfor sustaining production. Often, classificatorydesigns – being cognitive and linguistic in nature –do not reflect the day-to-day actions in farming.Instead of merely describing local soil classificationin relation to scientific criteria, understanding howdifferent (...) types of ethnolinguistic soil categories arerelated to crops, climate, subsistence needs,fertility, market demand, and cultural norms of thesociety would be far more effective in focusingresearch and development efforts.

Food insecurity and the loss of soil nutrients and productive capacity in Africa are serious problems in light of the rapidly growing African population. In semi-arid central Tanzania currently practiced traditional crop production systems are no longer adaptive. Organic crop production methods alone, while having the capacity to enable food security, are not feasible for these small-scale farmers because of the extra land, skill, resources, and 5–7 years needed to benefit from them—particularly for maize. Maize, grown by 94 % (...) of farmers, has substantial nitrogen needs. The most practical ways of satisfying maize nutrient needs is via integrated soil fertility management, a combination of organic and Green Revolution methods. Maize has been shown in research to outyield the indigenous crops millet and sorghum in nearly all situations including drought. Conservation Agriculture (CA) in Africa has two main categories—organic and herbicide-mediated. The organic version of CA, despite years of promotion, has had a low rate of adoption. Herbicide-mediated zero tillage CA via backpack sprayer can substantially increase conventional maize yields while at the same time nearly eliminating erosion and increasing rainwater capture up to fivefold. Glyphosate herbicide is a non-proprietary product produced in Africa and approved for small farm use. The systemic nature of glyphosate allows the killing of perennial grasses that would otherwise need deep plowing to kill. The rooted weed residues protect the soil from erosion. The risks of glyphosate use are substantially outweighed by the benefits of increased food security and crop system sustainability. (shrink)

Ethnopedology is the study of local knowledge of soil and land management in an ecological perspective. It is an emerging hybrid discipline that is a component of ethnoecology and stands to offer much for land-based studies. This paper reviews the field of ethnopedology in Latin America and compares some of the many case studies from that region. Various literature sources are considered, including the ethnographical, ethnohistorical, archaeological, geographical, agronomic, ethnoecological, and development studies. Our review invokes the theory of (...) ethnoecology that focuses on the linkages between kosmos, corpus, and praxis of local land-users. The main topics covered are the ethnohistorical and archaeological evidence of ethnopedology, local soil and land classification, local land management systems, local perceptions and beliefs of soil and land resources, and local soil fertility management. After analysing past and present research trends, recommendations are given on how ethnopedological studies can contribute to enhance sustainable land use and management in Latin America. (shrink)

Soil balancing is widely used in organic farming, but little is known about the practice because technical knowledge and goals for the practice are produced and negotiated within an alternative community of practice (CoP). We used a review of the private soil balancing literature and semi-structured interviews with farmers and consultants to document the knowledge, shared meanings, and goals of key actors within the soil balancing CoP. Our findings suggest this CoP is dominated by discourse between private (...) consultants and farmers, with few contributions to or from scientists or the peer reviewed literature. The idea of soil balancing is centered around improving soil quality through adjustments in Base Cation Saturation Ratios (BCSR), and practitioners report a wide range of positive agronomic outcomes. For most soil balancers, however, BCSR is only one part of a broader approach to soil health management that also utilizes traditional soil fertility recommendations and soil health-building cultural management practices. Meanwhile, a survey of land grant university soil fertility specialists and the peer-reviewed literature documented a high degree of skepticism and a lack of scientific evidence that BCSR can boost crop yields. We conclude that this scientific discourse reflects a disconnect from the practices and meanings used in the soil balancing CoP. While tensions between the dominant and niche agricultural knowledge systems are not unique, we believe a better appreciation for the nuanced meanings and goals within the soil balancing CoP present an opening for expanded collaborations with scientists doing research on soil health.

This article examines India’s response to the global soil health crisis. A longstanding centre of agricultural production and innovation, India has recently launched an ambitious soil health programme. The country’s Soil Health Card (SHC) Scheme intervenes in farm-scale decisions about efficient fertiliser use, envisioning farmers as managers and soil as a substrate for production. India is also home to one of the world’s largest alternative agriculture movements: natural farming. This puts farmer expertise at the centre of (...) soil fertility and attends to the wider ecological health of soils. Despite emerging as a mode of resistance to dominant agricultural systems, natural farming is now being delivered in increasingly bureaucratic ways by India’s state governments. This article offers Himachal Pradesh as a case study in how the soil is governed, drawing on 38 semi-structured interviews with scientists, agricultural officers, non-governmental organisation leaders, and activists. Rather than assess approaches to soil health according to their ecological bottom line, we examine the differing forms of knowledge, expertise and ‘truth’ in the SHC and Natural Farming approaches. Our analysis reveals discontinuities in how farmers are imagined, as well as continuities in how quasi-spiritual language combines in a bionationalist project, positing assumptions about the correct arrangement of life in nationalist terms. We point to a shift toward hybrid and pick-and-mix approaches to soil health, as farmers and their organisers are increasingly invested with the capacities to combine multiple options. We see a fracturing of expertise and the opening up of epistemic pluralism in responses to the soil fertility crisis. (shrink)

It is widely recognized that mineral fertilizers must play an important part in improving agricultural productivity in western Kenyan farming systems. This paper suggests that for this goal to be realized, farmers’ knowledge must be strengthened to improve their understanding of fertilizers and their use. We analyzed smallholder knowledge of fertilizers and nutrient management, and draw practical lessons from empirical collective fertilizer-response experiments. Data were gathered from the collective fertilizer-response trials, through focus group discussions, by participant observation, and via (...) in-depth interviews representing 40 households. The collective trials showed that the application of nitrogen (N) or phosphorous (P) alone was insufficient to enhance yields in the study area. The response to P on the trial plots was mainly influenced by incidences of the parasitic Striga weed, by spatial variability or gradients in soil fertility of the experimental plots, and by interactions with N levels. These results inspired farmer to design and conduct experiments to compare crop performance with and without fertilizer, and between types of fertilizers, or responses on different soils. Participating farmers were able to differentiate types of fertilizer, and understood rates of application and the roles of respective fertilizers in nutrient supply. However, notions were broadly generated by unsteady yield responses when fertilizers were used across different fertility gradients, association with high cost (especially if recommended rates were to be applied), association of fertilizer use with hybrids and certain crops, historical factors, among other main aspects. We identified that strengthening fertilizer knowledge must be tailored within existing, albeit imperfect, systems of crop and animal husbandry. Farmers’ perceptions cannot be changed by promoting more fertilizer use alone, but may require a more basic approach that, for example, encourages farmer experimentation and practices to enhance soil properties such as carbon build-up in impoverished local soils.

Farmers’ decisions to conserve natural resources generally and soil and water particularly are largely determined by their knowledge of the problems and perceived benefits of conservation. In Ethiopia, however, farmer perceptions of erosion problems and farmer conservation practices have received little analysis or use in conservation planning. This research examines farmers’ views of erosion problems and their conservation knowledge and practices in the Beressa watershed in the central highlands of Ethiopia. Data were obtained from a survey of 147 farm (...) households managing 713 fields during the 2002/2003 cropping season. In-depth interviews and group discussions were also held with the farmers to obtain additional information. The results show that 72% of the farmers reported erosion problems, and they recognized that conservation was necessary. However, they considered erosion to be severe mostly when visible signs – rills and gullies – appeared on their fields. The majority of the farmers believe that erosion could be halted, and they use a range of practices for erosion control and fertility improvement. These include contour plowing (83%), drainage ditches (82%), and stone terraces/bunds (73%). Nevertheless, despite decades of conservation intervention in the area, it appears that most farmers have developed negative attitudes towards externally recommended measures. The research concludes that under the conditions present in the Ethiopian central highlands, soil and water conservation interventions should consider farmers’ conservation knowledge and practices to improve acceptance and adoption of the recommendations.

Improving nitrogen (N) fertilizer management in agricultural systems is critical to meeting environmental goals while maintaining economically viable and productive food systems. This paper applies a farm systems framework to analyze how adoption of N management practices is related to different farming operation characteristics and the extent to which fertilizer, soil and irrigation practices are related to each other. We develop a multivariate probit regression model to analyze the interdependency of these adoption behaviors from 966 farmers across (...) three watersheds and diverse cropping systems in the Central Valley of California. Our analysis demonstrates that farmers adopt varying combinations or portfolios of practices, with the most common portfolio featuring a core set of fertilizer-focused practices. Irrigation infrastructure is an especially important farm operation characteristic for encouraging adoption of innovative practice portfolios that integrate water and fertilizer management. These findings highlight the ability for a farm systems approach to improve our understanding of farmer decision-making across diverse agricultural landscapes. (shrink)

Most aspects of agriculture in Cuba prior to 1989 were comparable to California: a high energy input, conventional agriculture (based on what the Cubans now call the “classical model”) in which little was done to protect the nation's soils from erosion, loss of fertility, salinization, and other forms of degradation. In stark contrast the new “Alternative Model,” which has been rapidly replacing the previous model since 1989, emphasizes soil conservation and rehabilitation and the general improvement of the nation's (...) soils as the key to sustaining low-input production and attainment of food security. One of the first steps in implementing the new model was the launching of an ambitious program to reclassify, evaluate, and map the nation's soils in great detail, and to interpret the maps for management of sustainable production. A main feature of this program is coordinated fertility trials to determine, for each combination of crop and soil, the minimum quantity of plant nutrients needed to produce the crop. The build up and maintenance of soil fertility and productivity is being accomplished with various organic and mineral amendments and biofertilizers, produced or mined within the country (locally, where possible) and through rational management utilizing cover crops, green manures, crop successions (intercropping and rotations), and other appropriate technologies. Rehabilitation of degraded soils, tillage reduction, reforestation, vermiculture, vermicomposting, and other forms of waste cycling are other features of the new model that are important to soil conservation and maintenance for sustainable production.

Ugandan smallholder farmers need to feed a growing population, but their efforts are hampered by declining soil fertility rates. Agricultural extension can facilitate farmers’ access to new practices and technologies, yet farmers are understandably often hesitant to adopt new behaviors. New knowledge assimilation is an important component of behavior change that is often overlooked or poorly addressed by current extension efforts. We implemented a Fertility Management Education Program in central Uganda to investigate smallholder farmers’ existing (...) class='Hi'>soil knowledge and their assimilation of new scientific concepts into their knowledge framework. Qualitative data were collected through participant observation, farmer interviews, and focus groups, and coded for using a priori and emergent themes. Our exploration revealed some notable similarities between farmers’ soil knowledge and scientific concepts, particularly in regards to soil health concepts, a discovery that could facilitate communication between extension agents and farmers. However, certain scientific concepts are either unknown to farmers or discordant with existing soil knowledge; these concepts are unlikely to be assimilated by farmers without convincing and concerted extension efforts. Importantly, we found that the combination of new scientific knowledge and hands-on experimentation with novel practices gave farmers far greater confidence in implementing improved soil management practices. Our study provides evidence that extension programs should engage directly with farmers’ existing soil knowledge to develop their understanding of key biological concepts and confidence in implementing improved practices.

Differences in perceptions and knowledge of crop diseases constitute a major obstacle in farmer–researcher cooperation, which is necessary for sustainable disease management. Farmers’ perceptions and management of crop diseases in the northern Ethiopian Regional State of Tigrai were investigated in order to harness their knowledge in the participatory development of integrated disease management (IDM) strategies. Knowledge of disease etiology and epidemiology, cultivar resistance, and reasons for the cultivation of susceptible cultivars were investigated in a total of 12 (...) tabias (towns) in ten weredas (districts). Perception of diseases involved both scientific and spiritual conceptual frameworks. Of the more than 30 crop diseases recorded on the major crops in the region, only rusts and powdery mildews (locally called humodia) and a few root rots were considered by farmers to be important. Farmers’ awareness of other diseases was extremely low; some highly damaging but less conspicuous diseases, such as faba bean chocolate spot and chickpea ascochyta blight (also called humodia), were not regarded by farmers as disease but as problems caused primarily by excessive soil moisture. Considering that some of these “unrecognized” diseases can cause complete yield loss and genetic erosion in epiphytotic years, there is an urgent need for bringing together farmers’ and scientists’ knowledge to complement each other. Even when farmers had access to disease-resistant or disease-tolerant cultivars, they grew susceptible local varieties because of multiple criteria including earliness, good yield in years with low humodia severity, suitability for home consumption, market demand/quality, and low soil fertility and land management requirements. Farmer innovation and knowledge were evident in their use of diverse disease control measures, but these were a mixture of the “useful and the useless.” Our findings stress the necessity for extension workers and researchers to understand and improve farmers’ knowledge of crop diseases, and farmers’ ability to observe and experiment, through the Farmer Field School or a similar experiential learning approach. These insights about farmers’ knowledge of crop diseases provide a basis for further collaborative maintenance of crop genetic diversity, development of germplasm, and IPM-related research in Africa.

This study reports on action research efforts that were aimed at developing institutional arrangements beneficial for soil fertility improvement. Three stages of action research are described and analyzed. We initially began by bringing stakeholders together in a platform to engage in a collaborative design of new arrangements. However, this effort was stymied mainly because conditions conducive for learning and negotiation were lacking. We then proceeded to support experimentation with alternative arrangements initiated by individual landowners and migrant farmers. The (...) implementation of these arrangements too ran into difficulties due to intra-family dynamics and ambiguities regarding land tenure. Further investigations to find out how ambiguities could be tackled revealed that the local actors themselves had taken initiatives towards developing institutional innovations to reduce ambiguities. However, there is still considerable scope for further development of these self-organized innovations. The article ends with a reflection on inter-disciplinary action research, where it is argued that making “mistakes” is an inherent and necessary characteristic in action research that aims to address complex social issues.

Many smallholders in the Amazon employ swidden (slash-and-burn) farming systems in which forest or forest fallows are the primary source of natural soil enrichment. With decreasing opportunities to claim natural forests for agriculture and shrinking landholdings, rotational agriculture on smaller holdings allows insufficient time for fallow to regenerate naturally into secondary forest. This case study examines how Peruvian farmers use “improved fallows” as an adaptive response to a situation of decreasing soil fertility and how the farmers describe (...) the rationale underlying the various actions taken in these modified fallow systems. The results indicate that farmers establish improved fallows using contextual ecological knowledge and various techniques to introduce a large diversity of tree species. This practice is also used to restore degraded land to agricultural production. The tasks of maintaining productivity on agricultural land and reforesting degraded areas is becoming increasingly urgent in the Amazon, making agricultural practices that involve reforestation and tree management highly relevant. Since swidden farming systems are the basis for the livelihoods of most Amazon smallholders, good farming practices elaborated by swidden farmers are important for sustainable small-scale family farming systems in the Amazon.

The Mediterranean region is facing major challenges for soil conservation and sustainable agriculture. Conservation agriculture (CA), including reduced soil disturbance, can help conserve soils and improve soil fertility, but its adoption in the Mediterranean region is limited. Examining farmers’ perceptions of soil and underlying sociocultural factors can help shed light on adoption of soil management practices. In this paper, we conducted a survey with 590 farmers across Morocco, Spain and Tunisia to explore concepts (...) that are cognitively associated with soil and perceptions of tillage. We also evaluated differences in perceptions of innovation, community, adaptive capacity, and responsibility for soil. We found that farmers’ cognitive associations with soil show awareness of soil as a living resource, go beyond agriculture and livelihoods to reveal cultural ties, and link to multiple levels of human needs. Beliefs about the benefits of tillage for water availability and yield persist among the surveyed farmers. We found that openness towards innovation, perceived adaptive capacity and responsibility for soil were associated with minimum tillage, whereas community integration was not. Education, age and farm lifestyle were also associated with differences in these perceptions. CA promotion in the Mediterranean should emphasize the multiple values of soil, should demonstrate how sufficient yields may be achieved alongside resilience to drought, and be tailored to differing levels of environmental awareness and economic needs across north and south.

A large section of the population (70%) of Uttarakhand largely depends upon agricultural based activities for their livelihood. Rural community of the mountains has developed several indigenous and traditional methods of farming to conserve the crop diversity and rejoice agrodiversity with religious and cultural vehemence.

Agrodiversity is an insurance against disease and extreme climatic fluctuations, (...) as a coping mechanism in times of scarcity, as a means to enhance overall productivity of farms, as a source of critical nutrition and medicine in the Himalayan region. The different traditional system of agriculture and indigenous method of maintaining soil fertility, socio-cultural and religious rituals has saved many crops that are under threatened category. But all these system and practices are ignored nauseatingly in hill agriculture policy, where more emphasis was given for plain areas. Less emphasis is being put on local systems that rely on existing natural, human, and social assets such as biodiversity, traditional knowledge, and social capital underpinning collective action to ensure food security. Of late, development planners have realized the importance of appropriate technologies and therefore have stressed the need for on-site training, and capacity building of user groups in rural areas of the region. Rural technology demonstration and training center have been supposed as a means disseminating technologies enabling improvement in the yield potential of farms, income generation from off-farm activities, and conservation and efficient use of natural resources. There is a strong need to bring desirable changes in the agricultural policy, research, and development in reference to mountainous regions. The present paper describe present scenario of agriculture, traditional, and socio-cultural practices of retaining soil fertility and agrodiversity, policy dimensions, and strategies for management of the Himalayan agroecosystems.

Sweetpotato-pig production is an important system that generates income, utilizes unmarketable crops, and provides manure for soil fertility maintenance. This system is widely practiced from Asia to Africa, with many local variations. Within this system, pigs are generally fed a low nutrient-dense diet, yielding low growth rates and low economic efficiency. Our project in Vietnam went through a process of situation analysis, participatory technology development (PTD), and scaling up over a seven-year period to improve sweetpotato-pig production and to (...) disseminate developed technologies. The situation analysis included a series of pig production assessments in several provinces in northern and southern Vietnam, and pig supply-market chain identification was conducted in 13 provinces. The analysis of these studies informed the project of the following: (1) appropriate locations for our activities; (2) seasonal available feedstuff and farmers’ feeding practices; (3) market fluctuation and requirements; and (4) feeding and management improvement needs based on which the subsequent phase of PTD was designed. The PTD involved a limited number of farmers participating in sweetpotato varietal selection, sweetpotato root and vine silage processing, seasonal feeding combination, and pig feeding with balanced crop-feed diet and silage. Six years of multi-location and multi-season sweetpotato selection resulted in a few promising varieties that yielded up to 75% more dry matter and have since been formally released. The most significant results of silage processing and feeding trials include improved growth, higher feeding efficiency, increased year-round local feedstuff, and considerable labor reduction from eliminated cooking and vine cutting. Once these technologies were developed, a farmer-to-farmer training model was designed for scaling up the adoption and impact. Farmer trainers from seven communes in seven provinces received training in these technologies. In turn, they undertook the responsibility of training other farmers on sweetpotato selection, processing, and feeding. An impact study was also administered to monitor and evaluate (M&E) the dissemination process and to document the impact of the new technologies and farmer-to-farmer training model on pig growth and farmer income generation. The results showed that both participating and non-participating farmers have taken up the technologies, although the former demonstrates higher rates of adoption than the latter. The participants also generated more income and saved more labor from the adoption of the technologies. While the scaling up and M&E activities are on-going, the project has since broadened from a sweetpotato-pig system perspective to a pig-cropfeed system perspective based on farmers’ needs. It has included other crop feeds such as cassava and peanut stems in the research portfolio. New technologies based on on-going PTD will continuously be incorporated into the future training curriculum. (shrink)

Soil is fragile and nonrenewable but the most basic of natural resources. It has a capacity to tolerate continuous use but only with proper management. Improper soil management and indiscriminate use of chemicals have contributed to some severe global environmental issues, e.g., volatilization losses and contamination of natural waters by sediments and agricultural fertilizers and pesticides. The increasing substitution of energy for labor and other cultural inputs in agriculture is another issue. Fertilizers and chemicals account for (...) about 25% of the production energy investment in agriculture. An additional 60% is accounted for by machinery, gasoline, electricity, and power-related inputs. Fertilizer additions to cropland are not utilized fully and significant amounts, depending on conditions, are either lost in surface runoff or leached into the ground water. The annual discharge of dissolved solids from agricultural lands to the waterways in the USA is substantial. The increasing use of herbicides in agriculture is a threat to the quality of surface and ground water, although this threat is dependent upon both the chemistry of the compound and the ecosystem in which it is used. Especially within the Third World, development of an environmental ethic and environmental laws have not kept pace with the increase in pesticide use. Above all is the severe and global problem of soil degradation currently occurring at the rate of five to seven million hectares per year. The policy and moral aspects of these issues are discussed.

Background: The ethics of care and justice represent two modes of moral reasoning that nurses use in solving real-life ethical dilemmas. Research aim: The present study investigated what types of dilemmas nurses encounter in everyday work and to what extent they use care versus justice reasoning to solve them. Research design: The study used a cross-sectional survey design. Participants reported a real-life ethical dilemma and its resolution through an online survey. Open-ended data were analysed with an adjusted taxonomy of real-life (...) moral dilemmas and moral orientations. Quantified data were analysed with statistical methods (χ2-test, analysis of variance). Participants and research context: Participants were 334 registered nurses and 177 practical nurses from four health and social care organisations in Finland. Ethical considerations: The study was approved by the Research Ethics Committee of Finnish Institute for Health and Welfare. Findings: Nurses reported six types of ethical dilemmas. Nurses used more care reasoning on the needs of others and conflicting demands dilemmas than on applying rules, social pressure and reacting to transgression dilemmas. Applying rules and needs of others dilemmas were the most common types of ethical dilemmas in both occupations. Practical nurses reported more non-ethical dilemmas than registered nurses did. Discussion: Ethical dilemmas of nurses are diverse, and the use of care and justice reasoning is differentiated according to the type of dilemma. Care reasoning dominates nurses’ ethical decision-making when responding to the needs of patients. Nurses use justice reasoning when they apply regimens, rules and procedures. In everyday ethics, care and justice reasoning complement each other. Conclusions: Highly regulated healthcare environments prefer rule-oriented justice reasoning that may supersede care reasoning in addressing patients’ situations. Focus on technical-professional expertise may further hamper nurses’ ethical decision-making. Nursing education and management should encourage nurses to use ethical concepts and values in their work. (shrink)

It is rooted in Confucianism, "the next school on up," the admonition of Chinese philosophy from the initial thinking on the road from the daily behavior persist in the pursuit of wisdom, relationships conducted by the "self" as the meaning of things by the event source. Everyone from family, community, political relations, to obtain a unique perspective, they participate in the growth of sperm heart and minds of thinking, their family and community relationships to adjust to a clearer, more meaningful position. Personal self-cultivation increased by the universe meaning, and meaning of the universe has increased over the coming anti-In order for individuals to provide a self fertile soil. For the eloquent Pythagoras, the holistic way of life he described as philosophia-"the love of wisdom"-while entailing the contemplation of abstract, theoretical science, involved much more importantly religious practices based upon the immortality of the soul, ascetic observances, a program of social and political reform, ethical reflection, a physical regimen, and even dietary prescriptions and prohibitions. But this conception of philosophy as a holistic vision of the good life faded in time, and gave way to the search for apodictic knowledge and its promise of certainty. "Knowledge" and "truth" became the vocabulary of systematic philosophy, and "wisdom" was banished from conversation in the corridors of the Western academy. The worship of the theoretically and spiritually abstract meant that in the fullness of time practical wisdom , rhetoric, and the aesthetic were relegated to the down side of a prevailing dualism. The Chinese cultural narrative unfolded differently. Grounded in the Confucian exhortation-"Study what is near at hand and aspire to what is lofty the next school on the up"-the Chinese philosophical narrative has from earliest times sustained a commitment to the pursuit of wisdom by understanding personal cultivation as the ultimate source of an emergent cosmic meaning. It is the revolution currently taking place within the Western philosophical community as an attempt to reinstate wisdom that provides an opening and an invitation to take Chinese philosophy and culture more seriously. An internal critique continues to be waged within professional Western philosophy under the many banners of process philosophy, hermeneutics, post-modernism, neo-pragmatism, neo-Marxism, deconstructionism, feminist philosophy , and so on, that takes as a shared target what Robert Solomon has called "the transcendental pretense"-idealism, objectivism, logocentrism, essentialism, the master narrative, "the myth of the given"-the familiar reductionistic "isms" that have emerged as putatively novel choices as philosophers switch horses on the merry-go-round of systematic philosophy. In place of a Cartesian philosophical language that privileges the function of clear and distinct ideas in our quest for an objective certainty, vocabularies of process, change, and indeed productive vagueness have increasingly come into vogue. These recent developments in Anglo-European philosophy itself have begun to foreground interpretative vocabularies more relevant to the articulation of Chinese culture. In this essay, I will argue that the pragmatic theory of truth as expounded by William James and particularly John Dewey is an attempt to reauthorize "wisdom" as a philosophical goal in the Western philosophical narrative. This development opens a space for a conversation between Deweyan pragmatism and Confucianism on how best to achieve it. (shrink)

Precision agriculture is a breakthrough in digital farming technology, which facilitates the application of precise and exact amount of input level of water and fertilizer to the crop at the required time for increasing the yield. Since agriculture relies on direct rainfall than irrigation and the prediction of rainfall date is easily available from web source, the integration of rainfall prediction with precision agriculture helps to regulate the water consumption in farms. In this work, an edge computing model is developed (...) for predicting soil moisture in real time and managing the water usage in accordance with rain prediction. A soil moisture prediction hybrid algorithm has been developed that revolves around the decision-making techniques with live environmental parameters including weather parameters for the prediction of soil moisture through the impact of precipitation. Numerous algorithms with the combination of regression + clustering are estimated, and it is inferred that XGBoost + k-means outperforms other algorithmic combinations that is deployed in edge model. This model is used as an intermediary between the end IoT devices and cloud that results in the saving of computationally intensive processing performed on cloud servers. The servers located on a local edge network perform the developed algorithmic computations. Avoiding transmission over the cloud results in significant latency, response time, and computation power savings and therefore increases the efficiency of data transfer. The proposed edge computing model is implemented in Raspberry Pi as an edge, Heroku as cloud, and edge nodes as the combination of Pi with actuators and sensors. The monitored data from Pi are stored in MongoDB webserver that is controlled by Web dashboard. Finally, the developed model is implemented in cloud and edge where the edge server implementation performs better in terms of latency, bandwidth, throughput, response time, and CPU memory usage.

What is philosophically interesting about how soil is managed and categorized? This paper begins by investigating how different soil ontologies develop and change as they are used within different social communities. Analyzing empirical evidence from soil science, ethnopedology, sociology, and agricultural extension reveals that efforts to categorize soil are not limited to current scientific soil classifications but also include those based in social ontologies of soil. I examine three of these soil social ontologies: (...) (1) local and Indigenous classifications farmers and farming communities use to conceptualize their relationships with soil in their fields; (2) categorizations ascribed to farmers in virtue of their agricultural goals and economic priorities relied upon in sociological research; and (3) federal agency classifications of land capability employed by agricultural scientists. Studying the interplay of these social ontologies shows how assessing soil properties and capabilities are the result of previous agricultural strategies informed by culture, agroecological history, weather, soil biodiversity, crop rotation, and the goals held by decision-makers. The paper then identifies the soil relationships and interactions that constitute ontology-making activities. Building on recent work, I outline a novel interactive account of perspectival realism grounded in agricultural extension research and ethnopedological data that captures the haptic nature of farmers’ soil strategies. This interactive account explains how ontologies are chosen, why they are chosen, and how they interact and inform soil management decision-making. The paper concludes by examining the values laden in these ontologies and those which are causally implicated in the choice of soil management strategies. (shrink)

The aim of this paper is to show how the incorporation of metaphoric and poetic ways of thinking into the evaluation of a leadership development programme both captured the imagination of the employees and benefited the core business of a manufacturing production plant. Qualitative data evaluating the effectiveness of a substantial leadership programme were presented back to all members of a manufacturing plant (executive and non-executive) in the form of composite narratives over an eighteen-month period. Recommendations were derived from the (...) text of the narrative and were progressively implemented. Such was the positive response to the written narratives that senior management asked the researchers to present the narratives in the form of a ‘live’ performance. Evaluation through qualitative methodology lends itself to an imaginative interpretation and presentation. Although qualitative and quantitative data tend to be regarded as complementary in applied research, it was management’s decision to employ only a qualitative process in this instance. The decision was fortuitous, given that the leadership development programme was initially judged to be a failure, as it triggered a subsequent imaginative engagement that turned a failure into a success.

Given the increasing complexity of living in a global village, countries and regions that are parts of larger political entities frequently have considered the option of separating or seceding an ideal solution to their problems with a larger center of power. Isolation, a form of “freedom from,” has the potential of offering them free rein or “freedom to” manage their affairs for their own sake. Francophone playwrights and filmmakers have found the dialectical interplay between “freedom from” and “freedom to” fertile (...) dramatic soil for plays and films. Some of them work in both of these and other genres. These works seem to ask the same question: Is it desirable or possible to achieve both, even in ideal isolation, without suffering cultural stagnation or repeating the abuse of power on the part of the political center that led to the separation? This article explores the answers to this question given in the plays of Aimée Césaire, Anne Hébert, and Wajdi Mouawad within the greater context for this issue found in J. M. Coetzee’s Waiting for the Barbarians and Azouz Begag’s Un Mouton dans la baignoire and in francophone films by Raoul Peck, Bertrand Tavernier, Claire Denis, Rachid Bouchareb, Ousmane Sembène, Michael Haneke, and Mathieu Kasovitz.

Industrialized agriculture currently substitutes many of the ecological functions of soil micro-organisms, macroinvertebrates, wild plants, and vertebrate animals with high cost inputs of pesticides and fertilizers. Enhanced biological diversity potentially offers agricultural producers a means of reducing the cost of their production. Conservation of biodiversity in agricultural landscapes may be greatly enhanced by the adoption of certain crop management practices, such as reduced pesticide usage or measures to prevent soil erosion. Still, the vast monocultures comprising the crop (...) area in many Canadian agricultural landscapes are often of limited conservation value, thus the inclusion of appropriate wildlife habitat in and around arable lands is a fundamental prerequisite for the integration of wild species within agricultural landscapes. This review of current literature considers the potential for non-crop areas within agricultural landscapes to be reservoirs of agronomically beneficial organisms including plants, invertebrates, and vertebrate species. Non-crop habitats adjacent to crop land have been identified as significant for the maintenance of plant species diversity, for the conservation of beneficial pollinating and predatory insects, and as essential habitat for birds. A key component for enhancement of biodiversity is the reintroduction of landscape heterogeneity by (1) protection and enhancement of key non-crop areas, (2) smaller fields and farms, and (3) a greater mixture of crops, through rotation, intercropping and regional diversification. The benefits of increased biodiversity within arable lands are reviewed for various species groups. In the Canadian context, any serious attempt to derive significant agronomic benefit from increased biodiversity will require considerable changes in the agricultural programs and policies which shape mainstream industrialized agriculture. The problems of crop depredation by vertebrate species, weed and insect competition, which still represent significant impediments to the creation and proper management of wildlife habitat, are also discussed.

Considerable attention has focussed on the potential of indigenous agricultural knowledge for sustainable development. Drawing upon fieldwork on the soil and water management principles of rice farming systems in Senegambia, this paper examines the potential of the traditional system for a sustainable food security strategy. Problems with pumpirrigation are reviewed as well as previous efforts in swamp rice development. It is argued that sustainability depends on more than ecological factors and in particular, requires sensitivity to socio-economic parameters such (...) as the labor demands of the food security strategy, the sexual division of labor, and food pricing policies.

This article looks at how imaginaries of land and climate play a role in farmland investment discourses and practices. Foreign farmland investors in the fertile black earth region of Russia and Ukraine have ‘celebrated’ soil fertility while largely ignoring climatic factors. The article shows a centuries-long history of outsiders coming to the region lured by the fertile soils, while grossly underestimating climate which has had disastrous implications for farm viability and the environment. Comparisons with historical and contemporary literature (...) on other regions suggest that the underestimation of climatic risks by newcomers is remarkably prevalent in resource frontiers. (shrink)

Technical best management practices are the dominant approach promoted to mitigate agriculture’s significant contributions to environmental degradation. Yet very few social science studies have examined how farmers actually use these practices. This study focuses on the outcomes of farmers’ technical best management practice adoption related to synthetic nitrogen fertilizer management in the context of Midwestern corn agriculture in the United States. Moving beyond predicting the adoption of nitrogen best management practices, I use structural equation modeling and (...) data from a sample of over 2500 farmers to analyze how the number of growing season applications a farmer uses influences the rate at which synthetic nitrogen is applied at the field-level. I find that each additional application of N during the growing season is associated with an average increase of 2.4 kg/ha in farmers’ average N application rate. This result counters expectation for the outcome of this practice and may suggest that structural pressures are leading farmers to use additional growing season applications to ensure sufficiently high N rates, rather than allowing them to reduce rates. I conclude by discussing the implication of this study for future research and policy. (shrink)

A theory’s fertility is one of the standard theoretical virtues. But how is it to be construed? In current philosophical discourse, particularly in the realism debate, theoretical fertility is usually understood in terms of novel success: a theory is fertile if it manages to make successful novel predictions. Another, more permissible, notion of fertility can be found in the work of Ernan McMullin. This kind of fertility, McMullin claims, gives us just as strong grounds for realism. (...) My paper critically assesses McMullin’s notion of fertility and its realist rationale. It concludes that McMullin’s preferred example, namely the fertile development of the Bohr-Sommerfeld model of the atom, does not support McMullin’s argument for realism. Although the implications for the realism debate are as of yet unclear, the case study offers some important methodological lessons. (shrink)

Workplace learning and competence development in work are frequently used concepts. A wide spread notion is that societal, institutional, and organizational changes require the development of knowledge, methods and strategies for learning at workplaces, in both public and private enterprises. In research on learning and competence development at work, the organizational learning and development as well as individual accomplishments are investigated from various perspectives and in different contexts. The theoretical base for research projects can, accordingly, be focused at a number (...) of organizational and system levels. This paper describes a research project called "Workplace development and learning in elder care" in which learning and knowledge were key issues and where Activity Theory was used as the theoretical base. The project was joint project between two research and development field units. These were UFFE, a municipal social services’ field research unit, and Äldrecentrum Västerbotten, a county council field research unit which aims to serve the interests of the elderly. The project was launched in the fall of 2000 and ended in the summer of 2003. I was employed part-time as a research leader at the municipal research unit and became the research leader for this particular project. A number of students, as well as employees from the county council geriatric care services and the municipal elder care participated in the project. The general aims of the project were to: a) investigate the prerequisites for development and learning; b) test and evaluate interventions at a workgroup level; and c) identify the need for new knowledge. The results were expected to be useful for the field research units as well as for the municipal and county eldercare services in their research and development work. I start with a presentation of the theoretical concepts and apply them in order to form a tentative hypothesis on the status of learning and knowledge in elder care. The next section contains a short description of the different parts of the project and the main results are presented. Finally, the results are discussed and related to the conditions and impact of workplace interventions. (shrink)

A persistent problem in the dominant agricultural development model is the imposition of technologies without regard to local processes and cultures. Even with the recent shift towards sustainability and agroecology, initiatives continue to overlook local knowledge. In this article we provide analysis of agroecological soil management in the Maya-Achi territory of Guatemala. The Achí, subject to five decades of interventions and development, present an interesting case study for assessing the complementarities and tensions between traditional, generally preventative practices and (...) external initiatives which tend to be curative. Our findings reveal a complex farming system that continues to rely on ancestral knowledge and practices, many of which display a high potential for sustainability and are deeply embedded in local culture. While some new practices have been incorporated into the traditional system, abandonment rates are high, and some extension methods have been paternalistic. The Achí are thirsty for new ideas to help them confront their current, unprecedented challenges. However, future collaborations should be built on existing local knowledge, which has contributed to the development of preventative and restorative practices still in use. Introduced technologies must coincide with local needs and socioecological context in a manner that encourages beneficial synergies, as well as horizontal learning/teaching processes. (shrink)

It is necessary to complement next‐generation sequencing data on the soil resistome with theoretical knowledge provided by ecological studies regarding the spread of antibiotic resistant bacteria (ARB) in the abiotic and, especially, biotic fraction of the soil ecosystem. Particularly, when ARB enter agricultural soils as a consequence of the application of animal manure as fertilizer, from a microbial ecology perspective, it is important to know their fate along the soil food web, that is, throughout that complex network (...) of feeding interactions among members of the soil biota that has crucial effects on species richness and ecosystem productivity and stability. It is critical to study how the ARB that enter the soil through the application of manure can reach other taxonomical groups (e.g., fungi, protists, nematodes, arthropods, earthworms), paying special attention to their presence in the gut microbiomes of mesofauna‐macrofauna and to the possibilities for horizontal gene transfer of antibiotic resistant genes.

Domestic livestock animals and soils must be considered together as part of an agroecosystem which includes plants. Soil sustainability may be simply defined as the maintenance of soil productivity for future generations. There are both positive and negative aspects concerning the role of animals in soil sustainability. In a positive sense, agroecosystems which include ruminant animals often also include hay forage-or pasture-based crops in the humid regions. Such crops stabilize the soil by decreasing erosion, improving (...) class='Hi'>soil structure and usually require fewer chemical inputs. Monogastric animal culture is based on an agroecosystem consisting of mainly grain crops. These crops can result in the soil being exposed to water and wind erosion although soil conservation practices that significantly reduce soil losses may be followed. The management of animal manures is not always compatible with soil conservation practices. Careful management of the nutrients in manure is absolutely necessary to avoid nitrate contamination of ground water or phosphorus loading of streams and lakes. In a negative sense, increases in animal livestock populations in association with human population growth are promoting desertification in the arid and semi-arid regions of the world. The key component for a fully compatible and acceptable association between domestic animals and soil productivity is proper management. Careful management of the components of an animal-based agroecosystem is required if soil productivity and environmental quality are to be maintained. Although we have much to learn, technologies are available to move a considerable way towards this ideal state. (shrink)

This paper examines the intersection of environmental history and the history of science, specifically the impact of forestry science and fire management on land use and community dynamics in rural Portuguese mountains. It further traces the evolution of fire management from an ancestral rural practice to a scientific concern and the subsequent integration of vernacular knowledge with scientific methods. In the early twentieth century, fire was a common tool in rural Portugal for land clearance, pasture management, and (...) soil enrichment. Rooted in local knowledge, these practices were increasingly challenged by the rise of scientific forestry, which viewed fire primarily as a threat to be controlled. By the mid-twentieth century, Portuguese forestry policies had undergone a significant shift toward aggressive fire suppression and large-scale afforestation, reflecting a broader trend of prioritizing timber production and forest protection. Notable shifts occurred in the 1970s, marked, among other factors, by the increase in rural fires, a new socioecological vision for the forest and the introduction of prescribed fire techniques influenced by international models. The paper argues that the establishment of scientific fire management practices represents a merging of expert knowledge with local experience. This move represents a shift from exclusionary policies toward a more nuanced understanding of fire’s role in landscape management. An examination of these historical developments demonstrates the intricate interrelationship between science, the environment, policy, and local practices, illustrating the way knowledge systems both shape and are shaped by environmental governance.

Since the emergence of in-vitro fertilization, a specific set of technologies has been developed to address the problem of the ‘biological clock’. The medical extension of fertility time is accompanied by promissory narratives to help women synchronize conflicting biological and social temporalities. This possibility also has a transgressive potential by blurring one of the biological landmarks – the menopause – by which reproductive lives are organized and governed. These new ways of managing, measuring and controlling reproductive time have renewed (...) debates on the age limits of motherhood and the moral legitimacy of medical intervention into age-related fertility decline. Building on Amir’s feminist concept of biotemporality, this paper questions what happens when the ontological foundations of age-limited motherhood are disrupted by technologies which allow fertility to be extended. It discusses the reconfigurations of the ontological boundaries of the facts of life in the light of literature on reproductive technologies and temporality. Through the Swiss experience, the paper shows how medical experts are drawn into negotiating the ontological boundaries of age-limited motherhood along the binaries of the normal/pathological and the biological/social. Questioning the purpose of medical interventions in what are seen as facts of life, they produce different configurations of moral reasoning where what is natural undergoes shifts which both reinforce the normative order and subvert it.

What is sex and why is it important? Does marriage have a basic rationale? How should couples manage their fertility, and when and how should pregnancy be achieved? How should we respond to 'embryo adoption', teenage pregnancy, population growth, HIV/AIDS and other STIs, same-sex attraction? This collection of original essays looks at these and other pivotal issues in reproductive and sexual ethics, from the perspectives of philosophy, theology, psychology and economic science.

Three different types of low cost soil amendments, namely, EDTA, elemental S and N-fertilizer, were investigated with Vetiver grass, Vetiveria zizanioides (Linn.) Nash growing under highly mixed Cd–Pb contamination conditions. A significant increase (p < 0.05) in Cd and Pb accumulation were recorded in the shoots of all EDTA and N-fertilizer assisted treatments. The accumulation of Cd in 25 mmol EDTA/kg soil and 300 mmol N/kg soil showed relatively higher translocation factor (1.72 and 2.15) and percentage metal (...) efficacy (63.25 % and 68.22 %), respectively, compared to other treatments. However, it was observed that the increased application of elemental S may inhibit the availability of Pb translocation from soil-to-root and root-to-shoot. The study suggests that viable application of 25 mmol EDTA/kg, 300 mmol N/kg and 20 mmol S/kg soil have the potential to be used for soil amendment with Vetiver grass growing under contaminated mixed Cd–Pb soil conditions.

What humans know about the soil has material implications for the future of life on Earth. This paper looks at how soil is in the process of becoming visible as a living world at the heart of an epoch marked by technoscientific management of the environment. Scientific knowledge of the natural world is encountering a range of collectives and individuals striving to renew humans’ relationships with non human and organic ways of life. Soil is an interesting (...) case for the study of absence: all around, yet hardly apparent for many of us. Drawing upon Susan Leigh Star’s approach to “residues” and “infrastructures” allows soil to appear in all its ecological significance, as the final home to all residues and the dismissed infrastructure of bios. The aim of this essay is not only contributing to make soil visible, but to treat its passing into visibility as an event in its own right that reveals soil’s ambivalent material and cultural significance. As ecological visions come to reclaim this mistreated living ecosystem, it is not only the knowledge about soil that could be transformed but the soil itself. (shrink)
