Library ResourceDocuments et rapports de conférencedécembre, 2004Niger, Afrique, Afrique occidentale
In semi-arid south-western Niger, climatic variability, low productivity, poverty and institutional constraints limit the scope of agricultural production to meet the rising needs of the growing human population. The integration of crop and livestock production activities has long been seen as the most promising means for intensifying agriculture and improving productivity and food security. Livestock play key roles in mediating soil fertility through excreting manure and grazing crop residues and distant pastures.

Library ResourceDocuments et rapports de conférencedécembre, 2004
A classification of the major ruminant livestock production systems in West Africa is proposed. The proposed typology has two major classes of systems-sole livestock and crop-livestock. The sole livestock class has two systems (rangeland-based and landless) and the crop-livestock class has three sub-classes (annual crop-livestock, tree-crop-livestock and irrigated/flooded cropland-livestock). Within the 3 crop-livestock subclasses 13 systems defined by the dominant crops are identified.

The papers in this proceedings provide a cross section of science research in international agricultural research centres (IARCs), where the objectives and research foci within the Consultative Group on International Agricultural Research (CGIAR) have changed substantially in the 1990s. The book is divided in five sections. The first explores priority setting and research evaluation of commodity programmes. The second looks at institutional issues. The third explores issues related to commodity policies and food security.
