Peter AB - Modern agriculture is pushing traditional farmers to plant areas with monocultures of genetically uniform plants. This is risky because the plants are vulnerable to yield-limiting factors. Situ conservation methods have many benefits; although they do not provide a panacea for conserving natural sources of crop genetic resources. Researchers in certain countries have helped farmers return to traditional chinampas and multilayered, specied-rich gardens. In Bolivia, project AGRUCO is helping peasants recover their production autonomy.
