We also look at farming. Are we making sure that we're getting the latest seeds out to women so they can get a bigger yield off of their farms? A new type of seed that gets out to a man, let's say, that's drought resistant - because, of course, the rains are changing in Africa with climate change - if you don't put it in the hands of a woman, she won't necessarily get it. We look at breaking down all those barriers.
