Description

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.

About the Author

Ms. Eiman Fadul Bashir is an Assistant Professor at the Hydraulic Research Centre in Sudan with specialization in hydrology and hydraulic Engineering. She has conducted many applied research studies related to several aspects of irrigation water management, sedimentation in irrigation systems, design of irrigation systems and hydraulic structures, and rural water supply. She led SIRGPA project in Sudan, Funded by IFAD and implemented by UNESCO-IHE Institute and local partners. Ms. Eiman was the winner of the UNESCO Keizo Obuchi Research Award in 2008. She worked as a guest lecturer at Water, Engineering and Development Centre (WEDC) at Loughborough University in UK and contributed to the capacity building of young professionals on irrigation and water management under drought and water scarcity at the UNESCO-IHE Institute for water education, The Netherlands.

About the Series

IHE Delft PhD Thesis Series

IHE Delft PhD programme leads to a deepening of a field of specialisation. PhD fellows do scientific research, often with conclusions that directly influence their region. At IHE Delft, PhD researchers from around the world participate in problem-focused and solution-oriented research on development issues, resulting in an inspiring research environment. PhD fellows work together with other researchers from many countries dealing with topics related to water and the environment.

PhD research is often carried out in the ‘sandwich’ model. Preparation and final reporting – the first and last portion of the programme – are carried out in Delft, while actual research is done in the fellow’s home country, under co-supervision of a local institute. Regular contacts with the promotor are maintained through visits and long-distance communication. This enables researchers to employ solutions directly to problems in their geographical region.

IHE Delft PhD degrees are awarded jointly with a university. The degrees are highly valued and fully recognised in all parts of the world.
