Measuring the Water-Energy-Food Nexus // The Case of Latin America and the Caribbean Region

This paper presents an actual overview of the current state of the water-energy-food (WEF) nexus in Latin American and The Caribbean countries. The analysis is divided in terms of water, energy and food production for each country. The proposed WEF Nexus index comprises three key indicators per sector, considering availability, access, and stability of sector’s resources.

Informing Regional Water-Energy-Food Nexus with System Analysis and Interactive Visualization // A Case Study in the Great Ruaha River of Tanzania

In sub-Saharan Africa, water resources are scarce and subject to competing uses – especially for agricultural production, energy generation, and ecosystem services. These water intensive activities in the Usangu plains and the Ruaha National Park in southern Tanzania, present a typical case for such water competition at the water-energy-food nexus. This study tries to decipher the coupled human-nature interactions in the Great Ruaha River basin and effectively communicate the results to...

Quantifying the Sustainability of Water Availability // Water-Food-Energy-Ecosystem Nexus in the Niger River Basin

Water, food, energy, and the ecosystems they depend on interact with each other in highly complex and interlinked ways. These interdependencies can be traced particularly well in the context of a river basin, which is delineated by hydrological boundaries. Using the example of the Niger River Basin in West Africa, this study assesses the impact of climate and human/anthropogenic changes on the water, energy, food, and ecosystem sectors. It characterizes the resulting trade-offs through a set of...

The Water-Energy-Nexus in Australia // The Outcome of Two Crises

By John C. Radcliffe. The increasing world population will continue to pressure on potentially diminishing water resources and a rising demand for stable and reliable power supplies which have sufficient inertia and fast frequency response to manage unexpected supply problems. Frequently, water and energy policies are developed under different arms of government with few links between them. Under the Australian constitution, the management of water is a states/territories responsibility. Several...

Moving from Theory to Practice in the Water–Energy–Food Nexus // An Evaluation of Existing Models and Frameworks

By Sa'd Shannak, Daniel Mabrey, Michele Vittorio. The recognition of the interlinked nature of water, energy and food (WEF) resources has resulted in growing momentum to change the approaches for managing these interlinked resources. Initially, models were developed as a mean of integrated methodology for watershed management. However, most countries and governments manage natural resources with different institutions that have their own mission and objectives. This has mostly led to huge...

Governing the Water-Energy-Food Nexus Related to Hydropower on Shared Rivers // The Role of Regional Organizations

By Ines Dombrowsky and Oliver Hensengerth. An evolving literature on the Water-Energy-Food (WEF) nexus argues that there is a need to better understand the conditions under which nexus coordination may occur. A case in point are hydropower investments on shared rivers which might impact the provision of energy, water and food security across borders. In international basins, governing the WEF nexus impacts of hydropower relies on voluntary negotiations between the respective countries involved....

Global Water Transfer Megaprojects // A Potential Solution for the Water-Food-Energy Nexus?

By Oleksandra Shumilova, Klement Tockner, Michele Thieme, Anna Koska and Christiane Zarfl. This article introduces a global inventory on existing and planned Water Transfer Megaprojects (WTMP). The authors suggest, that due to the potential impacts of WTMP on regional and continental scales, natural or green infrastructure solutions should be seriously considered as alternatives or part of a gray-green infrastructure combined solution. WTMP are currently considered to be an engineering solution...

Southern Africa // Prospects for Improving Irrigated Agriculture in Southern Africa: Linking Water, Energy and Food

By Tafadzwanashe Mabhaudhi, Sylvester Mpandeli, Luxon Nhamo, Vimbayi G. P. Chimonyo, Charles Nhemachena, Aidan Senzanje, Dhesigen Naidoo and Albert T Modi. Increasing agricultural productivity has always been a prominent feature on the regional agenda due to a high incidence of food and nutrition insecurity. This review assessed the current status of irrigated agriculture in southern Africa from a water–energy–food (WEF) nexus perspective.
