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).

JRC Technical Report // Water-Energy-Food Nexus Interactions Assessment: Renewable Energy Sources to support Water Access and Quality in West Africa

By Kougias I., Szabó S., Scarlat N., Monforti F., Banja M., Bódis K., Moner-Girona M. Mitigating the big challenges of access to clean water, energy and poverty in Africa requires integrated solutions. The analysis of issues related to the water, energy, food and the ecosystem through a nexus approach, has attracted the interest of scientists, policy-makers and the private sector. The present Technical Report examines the potential of such an approach to create beneficial synergies between the...

Holistic Water-Energy-Food Nexus for Guiding Water Resources Planning // Matagorda County, Texas Case

By Muhammed I. Kulat, Rabi H. Mohtar and Francisco Olivera. The authors developed a holistic framework to provide sustainable scenarios that include feasible infrastructure interventions. The framework focuses on water and associated links with other resources, includes a unique analytic tool for quantifying scenarios, and ultimately produces a sustainability analysis of each scenario. Optimal scenarios are offered that consider site-specific dynamic resource interlinkages. The WEF nexus model...
