The purpose of this publication is to show how conservation agriculture can increase crop production while reducing erosion and reversing soil fertility decline, improving rural livelihoods and restoring the environment in developing countries. Soil organic matter and biological activity in the rooting zone, stimulated by continual additions of fresh organic material (crop residues and cover crops) are the basis of conservation agriculture, as described in the first chapter.

This publication will present efforts by FAO and partners on mapping the intervention area of the Great Green Wall initiative and restoration opportunities based on data gathered through Collect Earth and in support of presenting FAO's effort at COP22 in Marrakech on 14 November 2016.

African agrifood systems are being transformed by multinational capital. To date, research on this transformation has focused most intently on the rise of supermarkets and demand for African land. Multinational investment in African grain trading has received less attention. Using a range of qualitative methods and representative household survey data from Zambia, this article seeks to understand the causes and consequences of multinational investment in smallholder grain markets.
