Designing agroforestry innovations to increase their adoptability: a case study from Paraguay

The development of adoptable natural resource systems, to address the needs of rural populations, is a priority for many governments in less developed countries. This paper looks at agroforestry as an innovation, and at the factors which influence its adoptability. This is accomplished through an analysis of a case study on the development and diffusion of an agroforestry innovation in the Guayaybi region of Eastern Paraguay. In this case study a forestry extension team, working directly with the farmers, was successful in designing an adoptable agroforestry innovation. The innovation was ecologically adapted to the region and appeared to have good potential for economic return. It was readily adopted by the farmers who perceived it to have a relative economic advantage over their traditional land use systems. The agroforestry system was compatible with their agricultural practices and helped to meet their needs for wood products and fodder. The new system was simple to understand and easy to try on a limited basis which minimized risk. Also the tree species used were fast-growing, which impressed the farmers and made the plantations highly visible to others. This ‘observability’ of functioning agroforestry systems plus the belief in the potential for economic gain were the key factors in the rapid adoption of agroforestry as a new land use system.
