"Economics and Ecology of Diversification" offers a comprehensive analysis of the challenges and opportunities associated with the diversification of tree crops in tropical regions. In light of the ecological and socioeconomic crises caused by monocultures since the 1960s, the book highlights the reasons and timing when farmers adopt diversification strategies. It examines the different categories of farmers who choose to diversify, as well as the obstacles they must overcome. Additionally, the role of public and private policies in this process is discussed. The authors present 15 case studies from Africa, Latin America, Asia, and the Pacific, providing deeper insights into the economic and ecological aspects of family farming and its developments. The book is a valuable resource for anyone interested in the complex interactions between agriculture, the environment, and market conditions.
