We carried out field researches on millet dry farming system in sub-Saharan West Africa and India to assess the possibility of technology transfer between these two regions ("horizontal transfer"), not from north to south ("vertical transfer"). Major results obtained are as follows.
1. We confirmed that the Indian millet farming system can serve as a model which achieved productivity and sustainability at the same time. Indian farming system is characterized by intimate mutual association between agriculture and livestock raising.
2. In contrast, agriculture and livestock raising is basically practiced by different ethnic groups in sub-Saharan West Africa. Close cooperation between them does not seem to have evolved.
3. To evaluate the impact of technology transfer from temperate countries to tropical Africa, we made a case study in Thiongoni village in Mali. We revealed the mechanism how ridge cultivation using an animal-drawn French plow ("charrue") has caused a soil degradation. The co
nstruction of Markala Dam across Niger River also had a negative effect through loss of seasonally-flooded rice fields along the river, which lead to overdependence on upland fields.
4. Several different types of indigenous farming system, probably adapted to different environment, were recognized through the extensive survey in West Africa. A type is characterized by sowing and intercultivation by a long-handled hoe or spade with standing posture, and is distributed through drier part of Sahel. Another type, characterized by sowing and intercultivation by a short-handled hoe with bending posture, prevails in Sudan-savanna area. A characteristic intensive soil management systems were observed in Dogon plateau and Gondo plain.
5. In conclusion, transfer of millet farming technology from India to West Africa seems beneficial and requires further assessment of feasibility. However, the heterogeneity of environment and indigenous farming system in both donor and receiver areas, as stated above, should be taken into account. Less
