There are lots of biochar reources and climate change resources available on the internet; little of it applies to smallholders in the developing world. On this page we have tried to assemble a few relevant resources that range from the practical (the chemical composition of pig pee) to the big picture (models of innovation systems for development).

Our selection is very peculiar. If you have suggestions for additions, please send us the citation. We are happy to learn and to share.
