Abstract

Community welfare is a fundamental objective in achieving sustainable and equitable development, particularly in regions facing persistent urban–rural disparities. Despite various policy interventions, including fiscal transfers and targeted development programs at local levels, the determinants of community welfare remain a subject of debate. This study examines the key economic determinants of community welfare in Southeast Sulawesi Province, Indonesia, focusing on economic growth, income inequality, labor absorption, infrastructure availability, and investment. Using panel data regression analysis, this study investigates the causal relationships between these economic factors and community welfare across districts and cities in Southeast Sulawesi from 2012 to 2021, based on data from the Central Statistics Agency. The results indicate that labor absorption, income inequality, infrastructure development, and investment have significant effects on community welfare. Employment emerges as the most influential factor, suggesting that higher labor absorption plays a critical role in improving welfare outcomes. Income inequality shows a significant negative effect, indicating that increasing disparities reduce overall welfare. Infrastructure development and investment positively contribute to welfare by enhancing public services and expanding employment opportunities. In contrast, economic growth demonstrates a weaker impact compared to other determinants. This study contributes to the literature by providing empirical evidence that community welfare is more strongly influenced by employment creation and inequality reduction than by economic growth alone. The findings offer important policy implications for regional development planning, emphasizing the need for inclusive, labor-oriented, and infrastructure-supported development strategies to enhance welfare in developing regions.

Abstract

This study evaluates the spatio-temporal dynamics of land-cover change and their implications for the sustainability of ecosystem services in the Tiworo Watershed, Southeast Sulawesi, Indonesia, using an integrated ecological–economic framework. The analysis combined land cover datasets from 2014, 2019, and 2024 with sectoral gross regional domestic product (GRDP) data for agriculture, forestry, and fisheries, and applied the Tapio decoupling model to assess the relationship between economic growth and ecological pressure. Results revealed substantial expansion of built-up areas, plantations, and aquaculture ponds, primarily at the expense of mangrove forests and wetlands. Mangrove cover declined from 431.61 ha in 2014 to 306.77 ha in 2024, indicating increasing pressure on coastal ecosystems. Despite these changes, secondary dryland agriculture and forest areas remained relatively stable, suggesting partial resilience of the watershed landscape. Economically, the agriculture, forestry, and fisheries sector consistently contributed 38–41% of regional GRDP, confirming its strategic importance to local livelihoods and regional development. Decoupling analysis demonstrated absolute decoupling during 2014–2019 and 2014–2024, while relative decoupling occurred during 2019–2024, indicating that economic growth increasingly outpaced ecological degradation. However, localized ecosystem degradation, particularly in mangrove areas, remains a critical concern. These findings highlight that the Tiworo Watershed is transitioning toward more resource-efficient development, although long-term sustainability depends on adaptive watershed governance, stricter protection of vulnerable ecosystems, improved land-use planning, and strengthened community-based forest management. The study provides empirical evidence supporting the application of decoupling analysis at the tropical micro-watershed scale and contributes to the development of integrated forest and watershed management strategies in data-limited regions. Keywords: ecosystem services, forest management, land cover change, Tapio decoupling, Tiworo Watershed

Abstract

The urban heat island phenomenon has become a major concern for medium-sized tropical coastal cities, driven by interactions among land-use change, increasing building density, and the effectiveness of spatial planning. This paper examines how urban forest distribution and building density relate to urban heat island intensity using an urban ecology framework, remote sensing-based spatial analysis, including normalized difference vegetation index (NDVI), normalized difference built-up index (NDBI), and land surface temperature (LST), and spatial planning policy evaluation. The study combines Landsat imagery (2015–2023) with spatial planning documents, green space data, and stakeholder interviews. LST was obtained from NDVI-based emissivity-corrected digital number temperature-radiation-brightness conversion, and linear regression was used to determine the impact of NDVI and NDBI on LST. Based on the research findings, the two cities show different LST patterns. In Baubau, the temperature rise is largely influenced by building density, meaning the denser the buildings, the hotter the city becomes. In Kendari, on the other hand, temperature changes are more strongly influenced by vegetation density. Important ecological features, such as urban forests, mangrove forests, and coastal vegetation, remain scattered along the city’s outskirts. Their existence has not been fully integrated into urban spatial planning. As a follow-up to these findings, we emphasize the need for ecosystem-based measures to tackle the urban heat island effect. This includes tightening regulations on building density and green open spaces through permitting systems, as well as preserving remaining vegetation while developing well-integrated green corridors. Keywords: Baubau, building intensity, green open space, Kendari, land surface temperature, urban ecology
