Abstract

The disruption of hydrological cycle will reduce watershed's ability to store water, so that discharge in dry season decreases and discharge in rainy season increases. These problems are caused by changes in land cover from forested land to non-forested. This study aims to develop a scenario for land cover planning that should be applied in the Lisu Watershed, Barru Regency. This study is mapping based on non-experimental research. The data obtained were analyzed spatially by overlay method. The Soil Water Assessment Tool (SWAT) model is used in preparation of land cover planning scenarios to predict hydrological conditions. The results showed that scenario 2, namely land cover planning based on the district space map pattern is the best scenario. Addition of forest area to 61.60% resulting in the lowest yield of 3461.54 mm/year and 1519.53 mm/year. While the infiltration value produced is the highest infiltration value, which is 2299.20 mm/year.

Abstract

Wajo Regency ecosystem has an abundance of natural and ecological resources with great potential. However, the rapid pace of development activities followed by rapid land conversion has put the sustainability of the supporting ecosystems under pressure. Therefore, it is necessary to map the carrying capacity of the environment based on ecosystem services in Wajo Regency in order to identify the fit between environmental carrying capacity and development in Wajo Regency. Research is at Wajo Regency, through the identification of land cover. ecosystem service-based land capability based analysis is conducted using an Analysis Hierarchy Process to determine the value of ecosystem services from four classes of environmental services, namely water supply, food supply, natural disaster prevention and runoff, and flood management. Instructions for completing spatial patterns in Wajo Regency are performed by analyzing the overlap of the ecosystem service-based bearing capacity map with the Wajo Regency spatial pattern map to obtain a class of spatial pattern alignment. The orientation class is based on the carrying capacity of the land capability based based on ecosystem services to optimize land cover in Wajo Regency. Results of this study show that the land capability based of the four examined ecosystem services in Wajo Regency is dominated by high and low classes. The results of the evaluation of the RTRW by Wajo Regency show that an area of 42,048.97 ha corresponds to the carrying capacity based on ecosystem services. An area of 199,454.11 hectares of land is less oriented, but most of it is retained based on the direction of the spatial pattern. In terms of environmental sustainability based on ecosystem services, the most important land accesses are in the designated settlement areas, other protected areas and local protected areas.
