Most households in rural watershed regions of the Andes rely on agriculture or other natural-resource based activities for their livelihoods. SANREM researchers monitored the social, economic, and environmental effects of livelihood changes in watersheds of Chimbo, Ecuador, and Tiraque, Bolivia. The aim of this project was to improve farm families’ lives and incomes by finding profitable alternatives, to identify constraints to adopting these alternatives, and to encourage genetic diversity in crop selection.

Reducing soil erosion: SANREM scientists evaluated soil erosion in the region and its effects on agricultural productivity. They worked with community members to establish monitoring procedures, test different management practices, identify high value agricultural product marketing chains, and develop and implement local land use management plans. Research on these themes, especially the relationship between farming and soil loss, resulted in recommendations for raising incomes by 20 to 30 percent. Training students in watershed management: In 2009, the SANREM team took a group of five undergraduates to Ecuador. In less than four weeks, the students interviewed nearly 100 male and female farmers about conservation agriculture and their planting and harvesting practices. At the end of the trip, the students presented their research findings at a field day attended by farmers and representatives from local organizations in the Chimbo River watershed.
