I was reviewing the USAID web site and found some interesting PDF's on agricultural topics.
Effect of Hydraulic Head and Slope on Water Distribution Uniformity of a Low-cost Drip Irrigation System - 11 pgs 2008

And then the ugly.
Developing Conservation Agriculture Production Systems: An Analysis of Local Networks - 41pgs 2009

At first the article looks like it has permaculture values, no till, chop and drop, observation of local environment, reducing inputs, maximizing waste use.
But then it's end goal is preached of THHF, Tractors, Herbicides, Hybrid's & Financing (debt)
In the end the system only works if Government money is input.
Thought someone might search the site for information and this could be of help.
