Brief 1998

Autor: Sanders, J.H. Shapiro, Barry I. Ramuswamy, S.

Pessimistic views are often advanced about the future of agricultural development in sub-Saharan Africa, where rapid population and declining food production growth trends have been observed. This has especially been the case with regard to semi-arid Africa where rainfall is low and irregular, an...

Autor: Shapiro, Barry I. Sanders, J.H.

In semiarid West Africa, inorganic fertilizer use and sustainability objectives are complementary. With increasing population pressure and low levels of purchased inputs, crop yields in many regions are declining. Moderate use of inorganic fertilizer is required for increasing yields in a sustain...

Journal Article 1998

Autor: Sanders, J.H. Shapiro, Barry I. Ramaswamy, S.

This article proposes strategy for agricultural technology development for semi-arid West Africa. The strategy evaluation consists of two aspects: a) a review of the successes in the region; and b) analysis with mathematical programming of the potential impacts and constraints to various new tech...

Autor: Sanders, H.S. Ramaswamy, S. Shapiro, Barry I.

The paper proposes a theory of technology Development for semi-arid regions. It then evalautes the theory by reviewing the characteristics of technologies successfully introduced into the regions and, with modeling, identifying some constraints to further technology introduction of the type propo...

Autor: Shapiro, Barry I. Sanders, J.H.

This paper addresses the problem - with increasing values of land, crops and livestock in the semi-arid region, what happens to the livestock component? The conventional wisdom is that abundant land in more remote areas is more conductive to livestock Development than where human population densi...

Brief 1998

Autor: Shapiro, Barry I. Sanders, J.H.

An important debate is currently under way among researchers and policy makers about the relative merits of using organic versus inorganic fertilisers to improve soil fertility in semi-arid areas of sub-Saharan Africa. Environmentalists argue that use of inorganic fertiliser contributes to natura...
