Fantastic idea Ina!
I say apply for your grant, and if you get it, invite whom you will
Africa needs way more if this sort of projects. It is likely the most threatened continent by climate change, soil loss and poverty, but permaculture leaders are currently working in the most fertile areas of the world--go figure!
I'm increasingly convinced that those of us working in Africa need to build our own network and write out own books. There are so many intricacies to the wet/dry tropics that current permaculture training does not address. Do you have a website or blog of what your already doing?
Here's to a great collaborative future in Africa!
