Climate Change Adaptation Technology: Stonelines.

Stone lines or "bunds" slow down runoff, incerease water infiltration and
for the basis for improved production in semi-arid areas. At the same time,
sediment is captured behind these semi-permeable barriers. Stone lines were
originally a traditional technique in the Sahel, but have been improved by
careful construction, and through alingning on the contour. Stone lines are
suited to low slopes, high runoff and hand labour. A simple remedy that
really works. Wide and deep planting pits are often used in combination,
acting as microcatchments within the field.
