The impact of changing food choices on the blue water scarcity footprint and greenhouse gas emissions of the British diet: the example of potato, pasta and rice
T Hess, J Chatterton, A Daccache, A Williams - Journal of Cleaner …, 2016 - Elsevier
Food production is a major contributor to a country's environmental burden. However, the
burdens associated with individual foods vary significantly due to differing agricultural
systems and locations, post-harvest storage, manufacturing and transport requirements.
Dietary choices can therefore have a significant impact on the overall burdens associated
with food consumption. Previous studies have generally considered changes in the
proportion of animal-based foods in the diet or changes to a vegetarian, or a vegan diet …

The impact of healthier dietary scenarios on the global blue water scarcity footprint of food consumption in the UK
Large quantities of water are required to produce the food for a nation, some of which is
derived within the country and some associated with imported food commodities. In this
study, we consider the spatially explicit potential impact of alternative healthier eating
scenarios for the UK on global blue water scarcity using the concept of a water scarcity
footprint. The water required to produce the food consumed by the UK was estimated at 52.6
Gm 3/y of which 93% is from rainfall at the point where it falls and 7% is “blue” water …
