Family farms are by far the most numerous component of the agricultural sector in the Brazilian Amazon. However socially vital for the development of the region, these small landholdings' agricultural and cattle ranching activities frequently overdraw and degrade natural resources, threatening important ecosystem services. Predominant agricultural practices have been marked by shifting cultivation, with intense use of fire and low productivity, causing high rate of destruction of natural forests.

Mainstream agricultural research has focused primarily on technical and biological aspects and is aimed at controlling or manipulating nature through the use of external inputs, such as
agricultural chemicals or super seed. In developing countries, the results of this research have benefited some resource-rich farmers in well-endowed areas, were suitable to only a limited
extent for poorer farmers in the more favourable areas, and were - in most cases - completely inappropriate for small-scale farmers in marginal areas, e.g. in the mountains or the drylands.
