Contour Agroforestry Systems for Climate Adaptation and Dryland Ecosystems

- DAR (Dryland Agriculture Research) is a research initiative focused on regenerative farming in arid and semi-arid regions, where desertification and water scarcity threaten food production. - This page describes "contour agroforestry" — a technique that combines tree planting with crops along the natural contours (elevation lines) of a slope. The trees and their root systems slow water runoff, trap sediment, and improve soil moisture retention. - The approach is particularly relevant for dryland ecosystems, which cover about 40% of Earth's land surface and support roughly 2 billion people, many of them smallholder farmers vulnerable to climate shocks. - Contour agroforestry is presented as a low-cost, low-tech adaptation to climate change: it requires no irrigation infrastructure or synthetic inputs, relying instead on ecological design to buffer against droughts and floods.
