Spate irrigation has been practised over 100 years in the Red Sea coastal zone of Eritrea such as the Sheeb area. Main problem of the spate irrigation system is water shortage caused by irregular rainfall in the highlands of Eritrea and breaching of the irrigation structures by destructive big floods. Annually, a tremendous amount of soil with nutrients is eroded from the adjacent highlands, transported by seasonal streams (wadis) and deposited on the lowlands in the irrigated fields. The dominant types of soils of Sheeb area are the Fluvisols, which have good physical and chemical properties. The annual sedimentation on the spate fields enables the farmers to harvest a crop without application of fertilisers. A nutrient balance study revealed no soil mining in the spate fields. Farmers in Sheeb could obtain a more uniform water distribution over their fields with better levelling. Of the total area of Sheeb (8,000 ha), about 3,160 ha of land was classified as highly and moderately suitable for spate irrigation. When the flood diversion structures (at wadis Laba and Maiule) are made more permanent, an additional 2, 000 ha of land can be irrigated. In general, spate irrigation production system is a 'cost effective' system if the irrigation structures are properly maintained at low cost and if the fields receive enough water and nutrients.

Flood based irrigation in particular spate irrigation relies on variable flood scenarios occurring every year. Management of spate flood for spate irrigation must cope with the variability and uncertainty of water supply. Coping with water supply risks is often the only way to harness the opportunities for a productive use of water in arid environment. Integrating and strengthening community responses into irrigation policies and improvement plans could ensure sustainable and productive spate irrigated systems that can achieve food security for the poor population. This research analyses and evaluates risks and coping strategies developed by farming communities in the Gash spate irrigation system in Sudan, Eastern Africa. The research has synthesized different coping strategies developed by farmers, water user associations and water managers to cope with low, high and untimely flood risks. The research provide different frameworks that can assist with the identification of risk sources, pathways and propagation as well as evaluation of locally developed strategies at field, secondary and intake systems. The findings of this study contribute to scarce knowledge on spate irrigation system and provide scientifically sound and evidence-based insights to aid informed policy and decision making to improve productivity and sustainability of the spate irrigation systems.

FAO Eritrea, in partnership with the Ministry of Agriculture is implementing the national component of a global project entitled “Developing capacity in Agriculture Innovation System project: Scaling up the Tropical Agriculture Platform Framework”. The project aims to strengthen capacities to innovate for climate resilient agriculture and food system. One of the key activities of the project is the assessment of the Agricultural Innovation System (AIS) in Eritrea The assessment had the objectives to: identify critical gaps, needs, opportunities, and good practices to formulate workable recommendations aiming at strengthening and making AIS more effective; and develop an understanding of AIS and how it functions and supports climate-relevant transformation of agriculture and food systems. This report presents the main findings of the AIS assessment in Eritrea. The study identified major bottlenecks and entry points for strengthening AIS as well as inform policy and decision makers on AIS performance and made recommendations for its improvement.
