Excavating with cows
For several years now, ILCA (International Livestock Centre for Africa) has been successfully experimenting with the use of draught animal power to excavate ponds. A pair of cows harnessed to an easily made implement can move 13 cubic metres of earth or mud by day. To dig a 3,000 m3 pond the excavation thus costs about USD 1,000. Many watering holes in Ethiopia have had to be abandoned because of silting which can reach 1,000-2,000 m3 per year. Such siltation can now be controlled in this way without relying on costly mechanized technologies that are often inaccessible For more details, contact: S. Bunnig, A. Astatke or F.
