| PLEC is a project developed in response to demand from government and farmers for models of biodiversity conservation within agricultural systems. It was implemented in sub-humid and semi-arid environments along the foot slopes of Mount Meru in northern Tanzania in 1998-2002. Implementation was through establishment of demonstration sites in the respective ecological zones.
The project involved a multidisciplinary team of professionals and expert farmers (farmers with successful management models to train other farmers), extension staff, district and community representatives, researchers and trainers, decision and policy makers and NGOs. Team set up was dictated by the nature of activities and by the project operational unit -- “the landscape”. Farmers were lead persons, managing research and demonstration fields and other activities while researchers, extension and other staff facilitated the process.
Key outputs included increased on-farm species richness (crops, livestock and trees), improved and efficient use of agricultural inputs, increased crop and livestock yields and improved management of farms, especially on steep slopes. Others were improved household income and nutritional quality, improved farmer capacity to train other farmers, established farmer networks for exchange of information and knowledge, established by-laws on benefit sharing of products of conserved biodiversity and increased capacity of research and extension staff to work on biodiversity-related issues. Outputs also included improved skills of professionals in working with farmers, developed policy and technical recommendations, contribution to national database on agrodiversity components. Two years later, farmers still continue to identify with PLEC.
Dissemination of technologies and outputs was through informal and formal information and materials exchange between farmers, participation in agricultural shows, promotion of promising technologies by decision and policy makers, and production and distribution of technology leaflets, farmer training materials, radio and TV broadcasts and publications in journals and books.
