It will not come as news to anybody that Arizona’s water supply is in a pinch. Lake Mead is at a record low and if it falls even further, supplies to Arizona will be cut back by 13% to 17%.
Supplies are dwindling while demand is increasing – there can be no doubt that these trends are converging to a critical point in the not-too-distant future.
The currently prevalent plan to counter this is to build a desalinization plant on the coast of southern California and bring water in from there – a distance of some 300 miles. In addition to the monetary and environmental cost of transport, there are a number of other sustainability issues with this scheme.
Water from the left or water from above?
The Weekly Green spoke about the issue with Brad Lancaster, co-founder of Desert Harvesters and author of “Rainwater Harvesting for Drylands and Beyond“, a two volume opus on using our natural water supply efficiently and sustainably. In the course of the interview, you will learn about a huge local water resource which to date goes largely untapped!
This interview is the sequel to last week’s interview with Brad, which focused on cultivation of native food crops.
