Contrairement aux prévisions communément admises quant à l’aggravation du déclin économique de l’Afrique, une récente étude présente une vision alternative plus positive de l’avenir de ce continent.
This book synthesizes IFPRI's recent work on the role of gender in household decisionmaking in developing countries, provides evidence on how reducing gender gaps can contribute to improved food security, health, and nutrition in developing countries, and gives examples of interventions that actually work to reduce gender disparities.
The study reported in this paper measures differences in profitability betweenconservation farming (CF) practices and conventional agriculture by comparing the value ofdifferential output with the differential input costs.
There have been major shifts/changes in land use patterns in Rwanda over the past twelve years. A few striking observations include: As a percentage of total farmland, cultivated land increased. The increase in cultivated land occurred at the expense of pasture and fallow and woodlot.
This paper evaluates the future impact of soil degradation on national food security and land occupation in Ethiopia. It applies a spatial optimization model that maximizes national agricultural revenues under alternative scenarios of soil conservation, land accessibility and technology.

Severe soil erosion and food security problems are the most important issues in the Loess Plateau of northern China, which are closely related to the over-cultivation and poor management of marginal land resources. Alleviation of these unsustainability problems requires, among many other things, alternative and innovative cropping systems.
Econometric and simulation analyses indicate that land degradation does not threaten agricultural productivity growth and food security at the global level, but problems exist in some areas. Improving market performance could reduce erosion-induced yield losses to 0.1 percent per year and the number of hungry people in less-developed countries by 5 percent over 10 years.
