The Sustainability Model of Dryland Farming in Food-Insecure Regions: Structural Equation Modeling (SEM) Approach

Abstract

Agricultural sustainability is a prerequisite for reducing poverty and food insecurity. The readiness of food is closely linked to food security and the sustainability of dryland farming. It shows a vital position in food-insecure zones. This article purposes at presenting the analyses of the sustainability model of dryland farming in food-insecure regions. The research was carried out in East Nusa Tenggara Province, which is a region with a relatively high food insecurity level in Indonesia. The samples of farmers include 240 respondents taken using the combination of purposive and snowball samplings. Survey, interviews, and observation methods were applied to gather the data, which include main and supporting data. Data were examined with Structural Equation Modeling. The research model was built based on inputs, processes, outputs, food security, both directly and indirectly, affecting the sustainability of dryland farming. The outcomes of the study have shown that the sustainability of dryland farming can be improved by using government inputs and environmental inputs, reducing family resource inputs, using appropriate farming system models, utilizing government policies, increasing output, and strengthening the food security of farmers' households. Farmers are rational in making decisions about the sustainability of their farming management which is challenged with limitations.
