A team at IDEO led by Tatyana Mamout and Jessica Hastings has been working with the Bill & Melinda Gates Foundation recently to develop a toolkit to help NGO's apply human centered design methodologies to the work they do with small holder farmers. IDE, one of the NGO's supported by Gates, collaborated closely with the team and co-developed the toolkit and tested it in the field.

The toolkit can be downloaded here and while it would need to be adapted for use in other categories it may be a useful starting point for others who are working on design problems for the poor and under served.
