USAid, IFPRI and Oxford have developed, piloted and launched this new index on women's empowerment in agriculture which is accompanied by an impact evaluation methodology. There are also case studies that may be of interest. I would be interested in what people think of this, and how IFAD might use it and partner with the initiative.
Here is a copy of the document that describes the index.
And, here is the page on the launch of the initiative from the US government Feed the Future website.
