Rafael Merchan is a native of Cali, Colombia — where I lived for a few years, and very nice it was too. He lives in the US now but seems to travel the world a lot, checking out the local agriculture, and writes interestingly about it in a blog he calls International Agriculture and Development. His latest entry has some cool pictures of agricultural biodiversity in West Africa. I couldn’t find an RSS feed but I’ll be checking in regularly.
