Soil & Water Conservation on Water Balance in Burkina Faso

Laying stone bunds in fields is a well known technique to check runoff and to control erosion. Contour stone bunds are built with quarry rock or stones along the natural contour of the land to a height of 20-30 cm from the ground and spaced 20 to 50 m apart depending on the inclination of the terrain.The stone bunds form a barrier that slows down water runoff, allowing rainwater to seep into the soil and spread more evenly over the land. Compost is produced from organic wastes and increase soil organic matter and, combined with practices able to control soil erosion, provide soil organic matter enrichment.
