| 520 | |a Kerala‟s homegardens are ancient agroforestry systems celebrated for their ecological sustainability, their subsistence potential, and their high diversity of cultivated species. While homegardens have occupied Kerala‟s landscapes for thousands of years, some are worried that these systems are under threat from comparatively profitable plantations of rubber and other monoculture-based tree crops. Thus, the aim of this thesis is to examine the land-use dynamics in Kerala‟s agroforestry systems between 2001 and 2013. In Chapter 2, I analyze high resolution satellite imagery in order to broadly characterize agricultural and non-agricultural land-use changes in three panchayats (counties) of Kerala. The results indicate that: 1) wetlands (mostly paddy rice) are decreasing in all study regions; 2) built surfaces are increasing dramatically in all regions; and 3) agroforestry exists in a dynamic equilibrium with other land covers. In Chapter 3, I use a combination of quantitative surveys and semi-structured interviews to identify land-use changes and their drivers at the homegarden scale for 115 homegardens in 8 panchayats. Results indicate that almost all commercial and food crops, as well as livestock, are decreasing in production on homegardens, and that no crops are increasing. Nearly every farmer interviewed perceived a decline in agriculture in their region, and offered numerous interrelated explanations for why this might be so. Overall, Kerala‟s landscapes are undergoing a dynamic, multi-scale transition away from both homegarden- and plantation-based agriculture. | ||
