Showing results for: Water use/consumption
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.
This paper by FCRN member Dana Boyer examines how policy interventions at the city scale can affect three environmental outcomes of food production: greenhouse gas emissions, water use and land use. It uses India’s capital city Delhi as a case study. It sets out to assess the magnitude of city-scale food system actions as compared to certain actions which can be taken beyond the city boundary.
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.
This blog on the World Resources Institute’s (WRI) website discusses their collaboration with food multinational Mars in developing science-based sustainability targets for climate, land use, and water.
This paper discusses the water-energy-food nexus from a UK perspective with a focus on competing land demands. The research, led by the Tyndall Centre for Climate Change Research, suggests that current UK policies on water, energy and food are too fragmented to effectively tackle global challenges. The paper argues that there is a need for cross-sectoral policies and for new research to focus on the nexus between sectors, scales and timeframes to address this challenge.
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.
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.
This paper quantifies what the environmental impacts would be if the typical US diet were to shift in line with the USDA dietary recommendations. The paper has created a lot of interest and debate since it shows that shifting towards healthier diets in some cases can increase the energy, emission and water intensity of the diet. This is why we wanted to provide a more extensive summary and some commentary below. Please do read, share and add your own comments.
The food and agriculture (F&A) industry must increase production, availability and access to food significantly over the next ten years if it is to meet the demands of a larger, increasingly urban global population according to a new report presented by Rabobank at Expo Milano 2015.
This report by the UK’s Soil Association on cotton and climate change argues that switching to organic cotton could reduce the global warming impact of cotton production by 46% compared to non-organic cotton. Cotton has been called the world’s dirtiest agricultural commodity, owing to its heavy use of insecticides and water, high GHG emissions, and land use.
This paper reviewed data from six national studies to quantify food waste within the EU and its associated loss of water and nitrogen resources in the EU as well as the uncertainties of these values.
This study, which assesses the food supply available to more than 140 nations with populations greater than 1 million, shows that the globalization of trade is creating instability in the food distribution system. As the world population increases, placing increasing pressure on use of limited land and water resources, food demand has grown and globalisation has made the food supply more sensitive to environmental and market fluctuations.
Meat and Livestock Australia (MLA) reports that the Australian beef industry has reduced its environmental footprint over the past 30 years. The results are presented in a new paper in Agricultural Systems, and in a press-release MLA writes that:
