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...

L.A. bean production has stagnated due to the continuing yield declines. Production has been maintained by area expansion in some countries (Brazil); in others, it has increased due to a strong export demand from European and Venezuelan markets. High population and per capita income growth kept d...

La produccion del frijol en America Latina se ha estancado con las continuas disminuciones en los rendimientos. En algunos paises (Brasil), la produccion se ha mantenido mediante la expansion del area de cultivo; en otros, ha aumentado debido a una fuerte demanda de exportacion de los mercados eu...

Book Chapter 1980

Autor: Sanders, J.H. Schwartz, Howard F.

Beans are attacked by a large no. of plant pathogens and insect pests, many of which can reduce yields drastically. Farmers with small land holdings usually have limited resources but produce most of the beans in L.A. Control strategies feasible for these growers may be restricted to those strate...

El frijol es atacado por un gran no. de organismos fitopatogenos y plagas, muchas de las cuales disminuyen los rendimientos significativamente. Los agricultores que poseen pequenas parcelas tienen generalmente ingresos muy limitados pero producen casi todo el frijol en America Latina. Las estrate...

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...

Report 2001

Autor: Sanders, J.H. Ahmed, M.

With the increasing information now available on responding to the soil fertility problem in sub-Saharan Africa, better policy should be possible. Previously, there was not much acknowledgment in the literature that at the really low levels of N and P in much of the continent it was going to be n...

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...

In spite of substantial introduction of new sorghum and millet cultivars in semiarid Sub-Saharan Africa, there has been minimum aggregate impact on yields (FAO and ICRISAT, 1996: The World Sorghum Economies: Facts, Trends and Outlook. FAO, Rome, Italy and ICRISAT, Andhra Pradesh, India) in contra...

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...
