This article summarizes some major factors that influence the Water–Energy–Food (W–E–F) Security Nexus and how they are perceived in different basins. These findings are based on a survey that was undertaken for the Global Catchment Initiative (GCI) within the Global Water System Project (GWSP) complemented by case studies for a transboundary basin (the Lake Winnipeg Basin), a national basin (Yellow Basin in China), and a number of the basins in a nation (India). The analysis also includes ranking of river basin issues related to the WEF Nexus based on the views of experts in nine basins. Based on this analysis, factors that have affected the evolution of the W–E–F Nexus, including the applications of Earth observations, are discussed. The study concludes that the W–E–F Nexus could be an effective vehicle for advancing water and sustainability issues and recommends research and demonstration projects to test the extent to which the WEF framework could be helpful in increasing understanding and collaborative governance approaches.

The interconnectedness of water, energy and food production cycles translates into the interdependence of water, energy and food pricing. This paper interrogates the level of interconnectedness between these systems in South Africa and discusses how energy and water costs influence food prices in the country and affect the country's level of food security. The paper emphasizes that sustainable solutions to food security necessitate integrative thinking in the process of strategic planning for these resources.

According to estimates by the International Land Coalition based at the International Fund for Agricultural Development (IFAD), 57 million hectares of land have been leased to foreign investors since 2007. Current research has focused on human rights issues related to inward investment in land but has been ignorant of water resource issues and the challenges of managing scarce water. This handbook will be the first to address inward investment in land and its impact on water resources in Africa. The geographical scope of this book will be the African continent, where land has attracted the attention of risk-taking investors because much land is under-utilised marginalized land, with associated water resources and rapidly growing domestic food markets. The successful implementation of investment strategies in African agriculture could determine the future of more than one billion people. An important factor to note is that sub-Saharan Africa will, of all the continents, be hit hardest by climate change, population growth and food insecurity. Sensible investment in agriculture is therefore needed, however, at what costs and at whose expense? The book will also address the livelihoods theme and provide a holistic analysis of land and water grabbing in sub-Saharan Africa. Four other themes will addressed: politics, economics, the environment and the history of land investments in sub-Saharan Africa. The editors have involved a highly diverse group of expert researchers, who will review the pro- and anti-investment arguments, geopolitics, the role of capitalist investors, the environmental contexts and the political implications of, and reasons for, leasing millions of hectares in sub-Saharan Africa. To date, there has been no attempt to review land investments through a suite of different lenses, thus this handbook will differ significantly from existing research and publication.

Climate change is expected to considerably affect the water resources in the Indus River basin in Pakistan and thus agricultural production in the country. This article reports an analysis of the impacts of various climate scenarios on both water resources and food production out to 2050. While changes in water availability range from –12% to +24%, depending on the scenario, crop yield and production impacts are negative across all scenarios, and net food imports increase. We suggest a combination of accelerated investment in agricultural research and increased water-use efficiency in agriculture to reduce the adverse impacts of climate change on water and food.
