Integrating land and water management in smallholder livestock systems in sub Saharan Africa

These lower potential systems are generally based on mixed crop-livestock or pastoral activities, merging eventually into sparse and often dispersed systems with very low productivity or potential because of environmental constraints to production. In Africa the main crops are millet and sorghum. In the Middle East and North Africa the system is based on wheat, barley, and a wide variety of pulses and oil crops among others. Crop-livestock integration is important, especially when cattle are fertilizing fields while browsing on cereal straw after the harvest. In some of the systems, small-scale irrigation opportunities exist, allowing pastoralists to supplement their livelihoods in diet and income. New irrigated areas are developed in MNA through new drilling and pumping technologies. Market development is limited.

Managing Rainwater for Resilient Dryland Systems in Sub-Saharan Africa: Review of Evidences

Rainfed agriculture will continue to play an important role in achieving food security and reducing poverty in sub-Saharan Africa (SSA). But it is threatened by a combination of technology, policy, and institutional failures. Effects of recurrent drought and future climatic changes would affect rainfed systems and it would be most felt in SSA systems, where local institutions are not yet well prepared to respond to emerging climatic shocks. Rainwater management (RWM) is one strategy that could minimize drought effects through mapping, capturing, storing, and efficiently utilizing runoff and surface water emerging from farms and watershed for both productive purposes and ecosystem services. The extra water saved could be used to grow long maturing crops, producing more than one crop per season or diversify production systems. Enabling wider adoption of RWM interventions would improve the profitability of smallholder agriculture by increasing crop and livestock yield by factors of up to fivefold, while net returns on investment could double. However, adoptions of these interventions demand supportive policies and institutions, to enable farmer innovation, multi-institutional engagements, and collective action of actors at various levels. This is particularly critical in semiarid river basins, for instance the Nile basin, where because water availability is seasonal, upstream water towers are threatened by land degradation and deforestation and competition for surface water is becoming severe and could ignite regional conflict. This chapter contributes to the ongoing discussion on rainfed agriculture by not only inventorying the available RWM technologies and practices that could be used by small-scale farmers under various drought scenarios but also reviewing the challenges of technology uptake. It suggests institutional arrangements and policy recommendations required to improve uptake of RWM interventions at local, national, and regional levels.
