Shifting cultivation continues as the economic mainstay of upland communities in many countries in Southeast Asia. However, the conditions that historically underpinned the sustainability of rotations with long fallows have largely vanished. The imperative to evolve more permanent forms of land use has been exacerbated by rapid population growth, gazettement of remnant wildlands into protected areas, and state policies to sedentarize agriculture and discourage the use of fallows and fire. There are many compelling examples where shifting cultivators have successfully managed local resources to solve local problems. Technical approaches to stabilizing and improving productivity of shifting cultivation systems have not been notably successful. Farmer rejection of researcher-driven solutions has led to greater recognition of farmer constraints. This experience underlined the need for participatory, on-farm research approaches to identify solutions. The challenge is to document and evaluate indigenous strategies for intensification of shifting cultivation through a process of research and development. This process involves identification of promising indigenous practices, characterization of the practices, validation of the utility of the practice for other communities, extrapolation to other locations, verification with key farmers, and wide-scale extension.This revised version was published online in November 2005 with corrections to the Cover Date.  相似文献

Abstract

The forests of West Bengal have recently come under a comanagement initiative called Joint Forest Management. This paper will examine changing forestry regimes in southern West Bengal since the 1930s to suggest that the redefinition of forest management in the region since the mid 1980s cannot adequately be explained in terms of property rights. The nature of village community, overlapping jurisdictions of different agencies and groups in forest management, and the nature of expertise qualifying the scope of jurisdictions-that of foresters and villagers-are intersecting issues that have to be analyzed to understand the institutional politics of comanaging natural resources worldwide.  相似文献
