This research identifies the major crops and countries contributing to groundwater depletion. The authors found that 11 percent of unsustainable groundwater used for irrigation is embedded in international crop trade. They highlight the main exporters and importers of these crops, and the associated risks for local and global food and water security.

This study models the water demand of land acquisitions in Africa as a function of crop choice, local climate, and irrigation scenarios. Its authors distinguish between green and blue water, equating to water from rainfall and that provided to crops by irrigation respectively.

The ‘2016 Food, Water, Energy and Climate Outlook’ by the MIT Joint Program on the Science and Policy of Global Change finds that even if commitments from the  COP21 climate agreement are kept, many staple crops in various regions are still at risk of crop failures through extreme events, but at the same time, yields in many regions are projected to increase.

This report entitled 'Mitigating risks and vulnerabilities in the energy-food-water nexus in developing countries' analyses global nexus interconnections (such as the dependence of food systems on energy at every stage of the food value chain) and identifies key challenges for food, energy and water security, which include economic and population growth, resource depletion, environmental degradation, climate change and globalisation.

In this paper by researchers from Germany, Kenya, Australia and Sweden, a modeling approach is taken to ascertain the efficacy of applying improved water management techniques on a large scale to increase yields to help meet global demand for food.

The book provides an analysis of impacts of climate change on water for agriculture, and the adaptation strategies in water management to deal with these impacts.

The 2016 Global Risks Report (GRR) analyses the responses of 750 experts and decision-makers to the Global Risks Perception Survey, in which they were asked to give an estimate of the likelihood and impact of 29 different risks, categorised into 5 categories: societal (s), technological (t), economic (ec), environmental (en) and geopolitical (g).

In this article, researchers from Cranfield University, UK, examine the environmental burden associated with the production, manufacturing and distribution of potatoes, pasta and rice. The aim of the research is to highlight the difference that can be made to an individual’s environmental footprint (here focusing on water use and greenhouse gas (GHG) emissions) by making dietary changes within food groups, rather than between them.

In the years since publication of the first edition of “Food Wars” much has happened in the world of food policy. This new edition brings these developments fully up to date within the original analytical framework of competing paradigms or worldviews shaping the direction and decision-making within food politics and policy.

This paper entitled The environmental impact of climate change adaptation on land use and water quality published in Nature Climate Change says that adaptation to climate change could have profound environmental repercussions, potentially generating further pressures and threats for both local and global ecosystems.

This report sets out new climate change projections for Australia. It was produced by Commonwealth Scientific and Industrial Research Organisation (CSIRO) and funded by the Australian Government Department of the Environment, CSIRO and the Australian Bureau of Meteorology. The key findings from the report are copied as follows:

This study aims to assess the effect of five dietary scenarios – designed to promote healthier and more sustainable eating – on the blue water scarcity footprint of UK food consumption. The objectives are to estimate the total blue water consumed in producing food commodities consumed in the UK; the contribution, and geographical concentration, to global blue water scarcity; and the potential impact of alternative healthy eating scenarios on global blue water scarcity.

This study published by the European Commission's Joint Research Centre in the journal Environmental Research Letters analyses the water footprint of agricultural production and consumption in Europe. It looks at the net virtual water import of 365 European river basins for the period between 1996-2005 based on two diet scenarios – a healthy diet based upon food-based dietary guidelines and a vegetarian diet.
