In southern Benin, the legume cover crop ´ Mucuna pruriens var. utilis has been widely promoted for soil fertility improvement. Recent findings have shown, however, that the majority of farmers have not adopted it, and that alternative technologies are needed that are both attractive to farmers a...

The potential of alley cropping systems supplied with a limited amount of fertilizer to restore crop productivity on a degraded site and to maintain crop productivity on a recently cleared, non-degraded site on ‘terre de barre' soils in Southern Bénin was investigated from 1994 to 1996. Leucaena ...

Microarthropods, such as soil mites (Acari) and springtails (Collembola), with body width between 0.08 mm and 0.5 mm play important roles in soil fertility maintenance through their regulatory activities in decomposition and nutrient turnover. Observations were made at IITA, Ibadan, southwestern ...

Changes in agriculture and rural livelihoods in Africa are often attributed to the HIV epidemic. While acknowledging that the epidemic has devastated many families and communities because of excess morbidity and mortality, this review explores other causes of change in agriculture practices and p...

Sustainable use (in terms of nutrients) of soil resources by farmers in Sub-Saharan Africa is constrained by institutions and markets. This paper explores the case of northern Nigeria, by using a combination of multi-attribute utility theory and bio-economic modelling. This approach allowed us to...

Cassava is an important crop in India, with an area of 289,000 ha and production of 5.6 million t of fresh roots in 1991. It is mainly cultivated in Kerala, Tamil Nadu, Andhra Pradesh and in the Northeastern states. A large variation in cassava consumption exists between urban and rural areas in ...

In the past few years, the economy of Vietnam has developed very rapidly, and in agriculture, food production has been quite successful, especially that of rice. At the same time cassava production has changed from being a crop providing food for humans to being a cash crop. The planting of new c...
