Another example of how colonization and conquest destroyed (and is destroying) important knowledge. We have a lot to learn from the Mayan agricultural system.
This book is really well-argued, but pretty technical - makes a really clear case that:
1) the mayans didn't disappear because of poor agricultural management/deforestation
2) the mayans didn't disappear at all... they still live all over belize, guatemala and the yucatan
3) the mayans have a lot to teach the world about sustainable agroforestry and land management,
4) European-descendent scholarship has failed to understand mayan agriculture because Mayan agriculture looks so different from the european/colonialist model.
This also manages to be a helpful resource to anyone looking to imitate mayan agricultural techniques complete with huge appendix of native plants and their uses.
