What would you like included in a beginners book about permaculture in warm climates?

I am writing a book. The book is about how normal families, living in warm climates, can feed their families using permaculture principles. It will include a timeline about how our own has matured and changed over the 10 years, that has passed since we started it.
Right now some of the topics are:
What are permaculture and poly culture and how are they connected?
How to build a food forest garden
How to decide what to plant and when to plant
Working with nature creating ecosystems
Working with wildlife
Creating climate zones
Plants that are perennials in warm climates, that are annuals in cold climates
How to change dirt to soil
Tips and hacks for less work
Food preservation tips
Logistics and planning
Livestocks to think about.

What am I missing? I would love some feedback from people here, on topics that would be good to add.
