Natural resource tenure and economic feasibility of resource-based activities are two of the most important issues in the current debate around environmental degradation and rural poverty. While many analyses have blamed the ‘tragedy of the commons’ and government mismanagement for environmental destruction, this paper provides a case study of resin tapping in Honduras which formulates the hypotheses that common property regimes can be successful and that economic liberalization policies may be detrimental to community-level resource schemes. Over half of the 6000 farmer-resin tappers in Honduras are organized into forty-six co-operatives that market the tree sap, wood and other forest products. These activities combine the twin goals of community-based forest preservation and income generation. Established legally in 1974, the tapping groups have expanded to include a variety of organizational and technical arrangements. The two co-operatives of Villa Santa and San Juan de Ojojona demonstrate contrasting histories, ecological endowments and economic outcomes. Currently the Honduran resin tappers are facing problems over their access to forest resources, the fluctuating profitability of extractive activities and the stability of the co-operative organization. These three issues are relevant to a variety of community-based environmental activities, and the lessons of the Honduran experience can be applied to analyse the processes of environmental degradation and community response elsewhere in the Third World. 相似文献

In recent decades, there has been a noticeable increase in the use of quantitative techniques in the study of ethnicity and nationalism, without, however, a sufficient amount of reflection on how these techniques have contributed to our understanding of ethnic and national identities. As such, in this exchange three sets of authors answer questions about the degree to which it is possible to use quantitative data to measure ethnic and national identities, which types of methods are most suitable in measuring these identities and what the major research findings of this quantitative research are that were not possible using qualitative approaches. 相似文献
