This document helped me when I was co-writing a funding proposal with a focus on gender and conservation. I especially like this quote:
"Agency is at the heart of our model of empowerment; it refers to the capacity of women and girls to take purposeful action and pursue goals, free from the threat of violence or retribution." (BMGF)
I also found some really useful references in this document and there is a Gender equality tool box on their website here.
