I am loving this little handbook, The Climate Conscious Gardener, published by Brooklyn Botanic Garden. Why? They talk about permaculture and forest gardening as tools to mitigate climate change using each and every yard!!! Each contributor has a combo of accomplishments such as publications, research and of course, gardening.
It can be found here:

Forest gardens are more prevalent than ever before. If you want more information on edible forest gardens, you can simply google it. Message me if you want more information 🙂
