Indus Food Machine: Blind Spots in the Mega-irrigation System
The ‘Indus Food Machine’ is the world’s largest irrigation system. It has 14 million hectares under irrigation with 40 canal commands… producing (among others) 23 million tons of wheat, 9 million tons of rice and 10 million bales of cotton annually.
Unfortunately, the mega system is poorly managed: water rights are fuzzy and out-of-date; and the ‘water management’ is down to a few people largely concerned with allocation and delivery, working under immense political interference.
The latest post on TheWaterBlog- Managing Mega-irrigation- details these issues and offers two specific suggestions: (1) clarifying water rights and allocations; (2) channeling more surface water in areas of intense groundwater use, and reducing surface flows in other areas to stimulate pumping.
Are there other examples of blind spots in mega irrigation systems that you know of? Please share them in the Comments section of the blog, or by replying to this email.
