Abstract
The Forestry Pilot Plan set intomotion collectively-owned and managed forestry in overforty communities in Quintana Roo, Mexico and hasshown the promise of a forestry development model thatpromotes conservation by giving local people a genuinestake in sustainable resource management. Today, thelegacy of the PPF is under great pressure. Externally,neoliberal policy reform restructures agrarianproduction in ways that favor individual overcollective management of natural resources.Internally, organizational problems createinefficiencies within both forestry ejidos(cooperative agrarian communities) and theirintermediate level forestry civil societies. Peasants'capacity to defend their interests and dealeffectively with their production problems throughstrong representative organizations is beingundermined by new rules for economic associationwithin the ejidos and by the turning over of technicalservice financing to the market. Though organizationalinnovations within the ejidos hold positive potential,existing civil societies merit continued assistance askey actors promoting sustainable forestry. Studyingcommon property management regimes across multiplelevels and dimensions reveals that in Mexico, policyreform overlooks the crucial social resourcesrepresented by peasant organization, undermining thepossibility of sustainable forest management whileassigning the peasant most of the cost ofconservation. If conservation is indeed encouraged bythe genuine participation of those with a stake insustainable use of natural resources, national andinternational communities that value Mexico's tropicalforests should also invest in both social and economiccosts of conservation
