The Water-Land Nexus // Performance of Large Irrigation Schemes using the Example of the Gezira Scheme in Sudan

Worldwide, economic growth and changing lifestyles raise the demand for food production by almost 100% in 2050. Expanding irrigation is seen as a necessary step to meet this future pressure. In large irrigation schemes, crop productivity and efficiency in the use of inputs like water can be controlled and improved. However, many of such schemes in developing countries suffer from low performance and management failures.

The infographics provide an overview of challenges of such irrigation schemes and highlight solutions to increase performance. The case of Gezira Irrigation Scheme in Sudan, the world’s largest irrigation scheme under one management, is presented as an illustrative case of irrigation management challenges in the developing world.

The infographics have been dveloped by the Nexus Research Focus of the TH Köln – University of Applied Sciences under the leadership of the Institute for Technology in the Tropics (ITT) together with the DAAD-Funded project „Inquiry-Based Learning in the Curricula of Master-Level Courses in the Water and Land Nexus” (EBL-Nexus).
