Commercialization of homegardens in an Indonesian village: vegetation composition and functional changes

We examined structural and functional changes in the homegardens of Sukapura village, located in the upper Citarum Watershed of Indonesia, in relation to the increasing commercialization of agriculture. Our main purpose was to examine the structure and function of these homegardens during the rapid economic development of this area and the ecological, social, and economic implications of changes. A standard vegetation survey was used to describe the compositional and structural patterns of vegetation in the sampled homegardens, and interviewed 94 randomly selected respondents to help us understand the functions of their homegardens. The results suggest that commercialization in the agricultural sector has changed the structural patterns and functions of these homegardens. Plant diversity in commercialized (intensively managed) homegardens has decreased owing to the use of monocultures. The change from subsistence towards commercial farming has been accompanied by decreased plant diversity, higher risks, higher external inputs, increased instability, and reduced social equitability. The specific needs and preferences of the owners and market pressures were the main factors that triggered the development of intensive agriculture in the study area, leading to increased commercialization of homegardens.
