The case study I looked at was
MOSSI FARMERS OF BURKINA FASO REVIVE TERRACING AND WATER HARVESTING.... Early this century the Mossi put up lines of stones (bunds) on their cultivated land to build up terraces. Because of political instability this method was later abandoned. After a series of droughts in the 1970s, the bunds were revived. In the disastrous drought years of 1983 and 1984, crops grew on land with bunds, while adjoining fields grew nothing.
The most important lesson is the use of traditional methods to promote sustainable water use. In looking for follow-up information, I found a
study that investigated factors involved in the successful use of bunds. The investigators found that those who have more ownership rights over farmland tend to invest more in bunding.
