Effect of Socio-Economic and Institutional Factors on Different Choices of Food Production System Practiced in Home Gardens: A Case Study in Mahakanumulla Village Tank Cascade System

The global existence of small-scale food production at the household level has a wide range in terms of physical appearance and utilization. Household, market, and field gardens can be identified as three types of home food producti on systems in a village tank cascade system (VTCS) in the dry zone of Sri Lanka. The variation in food producti on systems adapted in VTCS serves differently for the community either by providing nutrient requirements or ensuri ng financial or food security. It is important to understand the determinants of this variation to support the comm unity to adapt the most suitable food production system for their well-being. Based on random utility theory, this study analyzes the socio-economic and institutional factors affecting the choice of food production system practiced in home gardens in Mahakanumulla VTCS. A revealed preference approach was employed to identify the current home garden choice of households. The decision to have a ho usehold garden is more driven by socio-economic and institutional factors rather than market gardens and field gard ens. The effect of these factors on the decision to have a field garden is comparatively less. Using these results policymakers can predict farm management decisions of households and plan evidence-based strategic governm ent intervention to meet the daily nutrient requirement, ensure food security, and mitigate food scarcity.
