Showing results for: Water security / scarcity
This article examines global overuse of freshwater resources and how more sustainable irrigation practices could impact other environmental and developmental targets in the SDGs. It finds that the main likely effects are 1) increased food prices due to lower productivity and/or production costs as water prices increase, and 2) cropland expansion and associated extra GHG emissions of 0.87 gigatonnes of carbon.
This new book, edited by Laura M. Pereira, Caitlin A. McElroy, Alexandra Littaye and Alexandra M. Girard, presents a diversity of collaborations between various governance actors in the management of the Food-Energy-Water (FEW) nexus and analyses the ability of emergent governance structures to cope with the complexity of future challenges across FEW systems worldwide.
Countries attending FAO’s 40th conference in Rome discussed climate change and food security from different perspectives linking climate-action, nutrition and migration to the 2030 Agenda for Sustainable Development. Four side events related to climate change took place during this conference, which can now be watched online.
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.
