Abstract

—The research aims to analyze the performance of the regional economy and the food crop sector amid pressures from changes in land cover and fluctuations in water discharge in the Konaweha Watershed, Southeast Sulawesi Province, Indonesia. The research data use secondary and primary data (land cover change survey). The database uses annual data (time series) between 2014-2021. Specifically, data on changes in land cover and water discharge in 2021 are compared with primary data (surveys). Regional economic data (GRDP) and food crops use secondary data. The results of the analysis show that the Konaweha Watershed during 2014-2021 experienced changes in land cover with a pattern of decreasing vegetation area and increasing built-up area. Water discharge decreased significantly with extreme decreases starting to occur in 2015, 2016, and 2017, and then starting to show a decrease in 2021. Watershed pressure which is marked by changes in land cover and decreased discharge in turn has an impact on regional economic performance, especially for food crops, horticulture, and plantations. It was found that changes in watershed land cover had significant implications for water discharge (decrease) so it had a negative impact on food availability (food crop commodities, horticultural commodities, and plantation crop commodities, respectively). If the pressure on watershed resources continues, it will have broad consequences (not only on the aspects studied in this study) that are difficult to predict. These results indicate that there is a need for immediate efforts to control this phenomenon in order to ensure food availability in the future.
