regional differences in blue water footprints and water scarcity

intolife's picture

Hello.

Could anyone please point me i the right direction for recent studies that have shown regional differences in the blue water footprint of agricultural products - livestock and horticulture?  specifically interested in studies that show relationships between blue water footprint / water irrigation and water stress.

Thanks, Will.

Hi Will,

I guess you're asking about specific results on real farms, rather than generic datasets like WRI's Aquaduct?  If so, I can't help you as yet - although we have recently started piloting a product water footprint certification and labelling scheme which might generate some results in this area.  Others are working in this area too (e.g. WWF's Water Stewardship scheme springs to mind).

Cheers,
John Kazer

Will, I'm not exactly sure what you're after either. There is a well-established work effort to take account of regional variation in water scarcity in whole-system water assessments. ISO14046 tries (with less than complete success IMHO) to indicate a way forward. There have been methods around for a few years, such as the work of Brad Ridoutt and Stephan Pfister, and case studies in which those have been applied; try - for example - one I worked on: Foster et al,  Journal of Cleaner Production 73 (2014) 269-274. For more up-to-date and comprehensive information, take a look at the work of the UNEP-SETAC working group WULCA (Water Use in LCA), at
http://wulca-waterlca.org/. Some publications listed there too: http://wulca-waterlca.org/publications.html

Good luck,

Chris Foster

Thanks Chris - yes, the stress-based indicators are definitely interesting, thanks for the links.

Thanks John, yeah I'm interested in how blue water footprints for different food products interact with relative scarcity of freshwater (the real data behind the media-ish comments about almonds from california, etc etc)
