O v e r the past several decades a development paradigm has emerged that seeks to link environmental quality and human welfare. Warnings of the adverse effects of deforestation, pollution, soil erosion, climate warming, and species extinction have focused worldwide attention on threatened natural habitats and species. Consequently, while the world’s remaining biological diversity is subject to massive loss and destruction, it is simultaneously being explored as a primary resource base for sustainable development.

Foreign assistance helps developing countries to achieve economic growth through wise use of natural resources. Conservation interventions and sustainable use of natural resources play a central role in this development. Conservation and utilization of genetic resources have traditionally proceeded as separate approaches. A conceptual approach to project design is presented encouraging greater interaction between those conserving crop genetic resources and those seeking their economic application in a sound land-use management plan. Projects illustrating this approach are being supported by the Agency for International Development. They suggest a paradigm for research and development allowing interdisciplinary activities targeting sustainable agriculture development. La ayuda extranjera contribuye a que los países en desarrollo logren un crecimiento económico a través del uso apropriado de sus recursos naturales. La interventión en la conservation y el uso sostenible de recursos naturales debe desempeñar un papel primordial en este desarrollo. La conservatión y utilization de recursos genéticos tradicionalmente se ha considerado como enfoques separados. Presentamos un enfoque conceptual para proyeetar el diseño, estimulando mayor interactión entre esos recursos de productos geneticos de conservación y aquellos que buscan su aplicación económica en un plan bien fundamentado de administratión en el uso de la tierra. La Agènda para el Desarrollo Internationál apoya proyectos que ilustran este sistema. Se sugiere un paradigma para la investigation y el desarrollo permitiendo en estos proyeetos actividades interdisciplinarias que enfoquen el desarrollo de una agricultura sostenible.

... Consequently, it is not surprising that the long-term existence of seminatural communities (6,000 years or more) has increased the grassland biodiversity due to the development of subspecies (and maybe even new species) with adaptations to the specific ecological conditions prevailing in a grazed or mowed grasssward. Potter et al. (1993) in their book give an overview of biodiversity conservation efforts at species and genetic levels, based on a number of case studies from different ecosystems of the world, also including several cases of agroecosystems and domesticated species. ...

... he soil by litter decomposition and rainfall are directly taken up gain by shallow rooted tree species. Disturbance of the natural vegetation can imply a significant loss of nutrients from the system, as a result of soil erosion, for example. The replacement method can be used to assess the value of e.g. nutrient losses resulting from soil erosion. Uhl et al. (1993) estimated the value of nutrients removed by forest clearance at US$ 3480 per ha according to the market prices of NPK fertilizers. ...

... Ethnobotanical studies have shown that Amazonian populations have a detailed and a diversified knowledge of their environment, including plants, animals and agroforestry management (Anderson 1990;Anderson and Ioris 1992;Anderson et al. 1995;Balick 1985;Posey 1983Posey , 1986Posey , 1987Posey et al. 1984), which can contribute to management and conservation purposes (Alcorn 1995;Berkes et al. 2000;Cohen et al. 1991). Currently, folk knowledge erosion has been observed in many studies, especially where native populations are influenced by economic and cultural transformations produced by national society and economy market trends (Plotkin 1988;Shanley and Rosa 2004). ...
