The carbon farming solution : a global toolkit of perennial crops and regenerative agriculture practices for climate change mitigation and food security

This is not a book you're supposed to read chronologically and even in its entirety - most of the book is more of a reference and handbook - but I almost did read everything from start to finish. This might just be one of the most important books out there on how to put the land to other uses and reverse global warming.

It's also a rare case of evidence-based literature coming out of an author with a so-called permaculture background. Toensmeier has been one of the few that has consistently encouraged that movement to become more based on data, current science and look out of the permaculture for other innovative land users (there are many examples in this book).

If you want to read a 'permaculture' book that is devoid of delusions and fairytales, this is the one you need to read.
