This chapter begins with a historical view on the subject of agricultural diversification as a response to local food production and food security in the Caribbean at regional and local levels. The objectives, based on the issues, controversies, and problems of farming in small island developing states (SIDS) in the Caribbean, would then be stated. This chapter then turns to the research methodology that is guided by the stated objectives as well as the nature of the subject and its theoretical underpinnings based on the proposed Diversified Integrated Farm Model, as noted in Chapters 2 and 3. Note well, this chapter invokes the literature on methodology, while the remaining chapters review and apply the literature on agricultural diversification, integration, waste conversion to raw material, and the transitional model of farm sustainability.
