Strategies for sustainable natural resource management
This brief describes two case studies as follows: "Sub-Saharan Africa, with the highest fertility rate in the world, faces increasing demographic pressure on its natural resource base.... Old strategies for coping with these new pressures on the natural resource base are becoming increasingly infeasible... Consequently, Africa's farmers require new solutions to address the increasing pressure on the continent's soil and water resources. Among hundreds of innovative efforts across the continent, two promising sets of responses have emerged in different locations....
Acción colectiva y derechos de propiedad en la gestión de la pesca
Hasta finales de la década de los sesenta, los pobladores de la isla San Salvador, en Filipinas, gozaban del acceso libre e ilimitado a los recursos naturales costeros. A principios de los años setenta, una ola de inmigración, combinada con la integración de la economía de la isla al mercado internacional de peces ornamentales, y el cambio hacia las operaciones de pesca destructivas, arruinaron las zonas pesqueras y dieron lugar a los conflictos.
Derechos de propiedad, acción colectiva y agrosilvicultura
La agrosilvicultura trata sobre los sistemas agrícolas integrados, en que los árboles juegan un papel prominente. La agrosilvicultura puede proporcionar una variedad de funciones o beneficios para los agricultores y las comunidades. Los más fáciles de identificar son los productos forestales utilizados por los humanos: leña para fuego, madera, vigas, frutas, medicinas y resinas. Un segundo grupo de beneficios consiste en los servicios que proporcionan los árboles a otras actividades agrícolas de los agricultores: abono vegetal, sombra, conservación de los suelos y estacas.
Adapting social science to the changing focus of international agricultural research. Proceedings of a Rockefeller Foundation-ILCA social science research fellows workshop
The papers in this proceedings provide a cross section of science research in international agricultural research centres (IARCs), where the objectives and research foci within the Consultative Group on International Agricultural Research (CGIAR) have changed substantially in the 1990s. The book is divided in five sections. The first explores priority setting and research evaluation of commodity programmes. The second looks at institutional issues. The third explores issues related to commodity policies and food security.

Development pathways and land management in Uganda
This paper investigates the patterns and determinants of change in income strategies ("development pathways"), land management, resource and human welfare conditions in Uganda since 1990, based upon a community-level survey conducted in 107 villages. Six dominant development pathways were found, all but one of which involved increasing specialization in already dominant activities. Of these, expansion of banana and coffee production was most associated with adoption of resource-conserving practices and improvements in resource conditions and welfare.
