Gezira is the Arabic word meaning ‘island* or ‘peninsula*. It crops up in place names throughout the Arab world, notably in the name Algeria which is an anglicized form of the Arabic al-guzayir, ‘the islands*. In the Sudan, Gezira means only one thing. It refers to that vast area of land which lies between the Blue and the White Nile. In particular, though, it refers to the part of that area which is irrigated and used for growing cotton, the staple export crop of the country.

This report is part of a series of case studies on the performance of irrigation systems in different countries. These studies focus on the extent to which the design of the irrigation system fosters effective water management and provides equitable, reliable, timely water distribution to farms (by analyzing water efficiencies, the effectiveness of maintenance, and cost recovery). The report recommends the design of the physical infrastructure, and states the impact on the management of these systems. Because of the comparative nature of this study, this report on the Gezira scheme in Sudan makes only passing references to some specific but critical aspects of this project, such as the capacity of the system to adapt to changing socio-economic conditions.

The Wellcome Trust is a charitable institution supporting medical and allied research throughout the world. This History of the Trust marks the celebration of its fiftieth anniversary in 1986. Professor A. Rupert Hall, a prominent science historian, long associated with the Trust, and B. A. Bembridge, a retired Trust scientist, have written this lucid and well informed account which charts the development of the organisation from its inception in 1936 to the present day. Within this framework, there is an underlying discussion of the 'philosophy' of the financial endowment of science and medicine. The Wellcome Trust has had an enormous impact on medical research over the years. This volume provides a unique insight into the development of a leading scientific research body, and its relevance to similar institutions the world over.

This book examines Nile water security through the morphology of the river: it uses the always changing form of the river as a theoretical and empirical device to map and understand how infrastructures and discourses dynamically interact with the Nile. By bringing a history of two centuries of dam development on the Nile in relation with the drainage of a hill slope in Ethiopia on the one hand and irrigation reform in Sudan on the other, the author shows how the scales, units and ‘populations’ figuring in projects to securitize the river emerge through the rearrangement of its water and sediments. The analysis of ‘Making water security’ is more than yet another story of how modern projects of water security have legitimized often violent dispossessions of Nile land and water. It shows how no water user is confined by the roles assigned by project engineers and planners. As ongoing modern ‘development’ of the river reduces the prospects for new large diversions of water, the targeted subjects of development and modernization make use of newly opened spaces to carve out their own projects. They creatively mobilize old irrigation and drainage infrastructures in ways that escape the universal logic of water security.

This open access book brings together research studies, developments, and application-related flash flood topics on wadi systems in arid regions. The major merit of this comprehensive book is its focus on research and technical papers as well as case study applications in different regions worldwide that cover many topics and answer several scientific questions. The book chapters comprehensively and significantly highlight different scientific research disciplines related to wadi flash floods, including climatology, hydrological models, new monitoring techniques, remote sensing techniques, field investigations, international collaboration projects, risk assessment and mitigation, sedimentation and sediment transport, and groundwater quality and quantity assessment and management. In this book, the contributing authors (engineers, researchers, and professionals) introduce their recent scientific findings to develop suitable, applicable, and innovative tools for forecasting, mitigation, and water management as well as society development under seven main research themes as follows: Part 1. Wadi Flash Flood Challenges and Strategies Part 2. Hydrometeorology and Climate Changes Part 3. Rainfall–Runoff Modeling and Approaches Part 4. Disaster Risk Reduction and Mitigation Part 5. Reservoir Sedimentation and Sediment Yield Part 6. Groundwater Management Part 7. Application and Case Studies The book includes selected high-quality papers from five series of the International Symposium on Flash Floods in Wadi Systems (ISFF) that were held in 2015, 2016, 2017, 2018, and 2020 in Japan, Egypt, Oman, Morocco, and Japan, respectively. These collections of chapters could provide valuable guidance and scientific content not only for academics, researchers, and students but also for decision-makers in the MENA region and worldwide.

The Nile is the world's longest river and sustains the livelihoods of millions of people across ten countries in Africa. This book provides unique and up-to-date insights on agriculture, water resources, governance, poverty, productivity, upstream-downstream linkages, innovations, future plans and their implications.

Water, Civilisation and Power in Sudan offers an alternative account of how water policy, violence, and economic modernisation are linked.

Urbanisation and long-lasting civil wars and conflict mean that the demographic pattern in Sudan is changing drastically. Nevertheless, 60%-80 % of Sudanese engage in subsistence agriculture. Agriculture remains a crucial sector in the economy as a major source of raw materials, food and foreign exchange. It employs the majority of the labour force, and serves as a potential vehicle for diversifying the economy. However, no rigorous studies have explained productivity in this sector in relation to food security. The situation has worsened because agriculture in particular has been neglected since the advent of oil production in the early 2000s. Moreover, Sudan's agricultural growth has been unbalanced, with the majority of irrigated agriculture concentrated in the Centre and a huge disparity in development indicators between the best- and worst-performing regions.Thus, studies show that the vast majority of Sudanese are reported to be food insecure, especially internally displaced persons and in conflict regions such as Darfur, Kordofan and other regions.

A summary of state-of-the-art research on how the river environment impacts biodiversity, species invasions, population dynamics, and the spread of waterborne disease. Blending laboratory, field and theoretical studies, it is the go-to reference for graduate students and researchers in river ecology, hydrology, and epidemiology.

A joint FAO and World Bank study which shows how the farming systems approach can be used to identify priorities for the reduction of hunger and poverty in the main farming systems of the six major developing regions of the world.
