Ciao, Giulia! So I'm an avid reader and as someone relatively new to the coffee world, I've been reading up a lot about the topics you mentioned. Here are some of my favorites so far:
1. Brewing Justice: Fair Trade Coffee, Sustainability and Survival by Daniel Jaffee
This is a great in-depth guide to how fair trade coffee works, its politics, and farmers' struggles for economic and cultural survival in a rapidly-changing industry.
2. Uncommon Grounds by Mark Pendergrast
This book takes you through the history of coffee which is foundational knowledge if you want to explore more about sustainability and Botanics. The book showcases the anthropology, economics, and history behind coffee.
3. Coffee Agroecology: A New Approach to Understanding Agricultural Biodiversity, Ecosystem Services and Sustainable Development by Ivette Perfecto and John Vandermeer
As you can probably tell from this long title, this is a bit of a heavy read. This is a very detailed and academic approach to understanding the issues at hand but if you want a scientific overview of coffee production, this is a must-read.
4. The Coffee Paradox by Benoît Daviron
This book examines the intersection of global markets, international trade, the commodity sector, and socio-economic issues plaguing coffee cultivation.
5. Where the Wild Coffee Grows: The Untold Story of Coffee from the Cloud Forests of Ethiopia to Your Cup by Jeff Koehler
In this book, the author examines how the industry is adapting to global change by focusing on the origins of Arabica coffee and how it may hold the key to sustainable coffee production in the future.
I hope this helps. If you check out any of these recommendations, I'd love to hear your thoughts on them.
