Background: Flood-prone areas present significant public health challenges, particularly in urbanized regions where inadequate drainage systems and water stagnation create ideal breeding grounds for disease vectors such as mosquitoes. This study investigates the relationship between flood risks and mosquito habitat proliferation in Gowa, South Sulawesi, Indonesia. Methods: By combining a comprehensive field survey with Geographic Information System (GIS) spatial mapping, the study aimed to identify environmental and infrastructural factors contributing to mosquito breeding, particularly Aedes aegypti, the primary vector for dengue and Zika virus. Findings: The results revealed that areas with poorly managed drainage systems and stagnant water were high-risk zones for mosquito breeding, correlating with increased mosquito densities and higher disease transmission potential. The study also found that rapid urbanization, combined with insufficient waste management, further exacerbates the risk by providing numerous breeding sites for mosquitoes. The findings support global observations that similar challenges in other tropical regions, including Brazil and Indonesia, contribute to the spread of mosquito-borne diseases. Conclusion: This research highlights the critical role of environmental infrastructure in controlling vector-borne diseases and emphasizes the need for improved urban planning, integrated vector control strategies—including better drainage infrastructure, community education, and regular sanitation practices—to reduce mosquito breeding sites. Overall, it provides valuable insights for local authorities and public health organizations, offering a framework for targeted interventions in flood-prone areas. Novelty/Originality of this article: The novelty of this study lies in combining GIS spatial mapping with field surveys to directly link flood-prone urban infrastructure and environmental factors to mosquito habitat proliferation, providing a framework for targeted, location-specific public health interventions.

Background: Peri-urban residential expansion in tropical Indonesia increasingly requires environmental baselines that connect routine climatic evidence with practical stormwater planning. This article develops a decadal rainfall baseline for the planned Sunville Residence area in Paccinongang, Somba Opu District, Gowa Regency, South Sulawesi, using a 2015-2024 monthly precipitation matrix extracted from NASA POWER data. Methods: The study applies descriptive climatology, interannual variability analysis, Schmidt-Ferguson wet-dry month classification, and Oldeman agroclimatic interpretation. Annual and monthly rainfall were summarized to identify seasonal concentration, wet and dry month structure, and planning-relevant hydrological implications. Findings: Mean annual rainfall reached 2,178.64 mm, with substantial interannual variability from 1,345.22 mm in 2019 to 2,955.56 mm in 2022. The rainfall regime was strongly seasonal, with December, January, February, November, and March forming the main wet-season core, while July to September represented the driest period. Using direct rainfall thresholds, the mean number of wet months was 7.3 and dry months was 3.2, producing a Schmidt-Ferguson Q value of 43.84%, which places the site in type C or moderately wet climate. Oldeman interpretation of the monthly climatological pattern indicates a C3-type agroclimate, characterized by approximately five wet months and four dry months. Conclusion: The baseline indicates that the site is not climatically dry; rather, its environmental risk is shaped by high wet-season water input, pronounced seasonality, and the possibility of rapid runoff if land conversion increases impervious cover. Novelty/Originality of this article: The article translates a project-level rainfall dataset into an international-style environmental planning approach by linking climate classification, peri-urban land conversion, and stormwater-sensitive design recommendations for a specific Indonesian residential development context.

Background: Peri-urban housing expansion in tropical Indonesia requires environmental baselines that are not limited to rainfall, but also capture wind direction, wind speed, temperature, solar radiation, humidity, and atmospheric pressure as interacting microclimatic controls. This study develops an integrated microclimate and wind-driven exposure baseline for the planned Sunville Residence area in Paccinongang, Somba Opu District, Gowa Regency, South Sulawesi. Methods: The manuscript applies a descriptive quantitative design using secondary meteorological data for 2015-2024 and a 2025 windrose overlay map. Variables included wind direction and speed, air temperature, solar radiation, relative humidity, and air pressure. The analysis combined descriptive statistics, seasonal interpretation, Beaufort-scale wind classification, wind-driven receptor interpretation, and climate-responsive site-planning synthesis. Findings: The site is characterized by dominant easterly flow toward the west, low average wind speed of approximately 1.5-2.0 m/s, and a dominant wind-speed band of 2-3 m/s representing about 35%-40% of observed conditions. Monthly mean air temperature ranged from 27.40 °C in July to 29.23 °C in November, while maximum temperature reached 33.12 °C in October. Mean solar radiation ranged from 1.77 kWh/m2/day in July to 2.90 kWh/m2/day in March. Relative humidity remained high, with mean values from 70.42% in September to 84.20% in February, while mean pressure was stable between 99.70 and 99.90 kPa. Conclusion: The study shows that climate-responsive residential planning in Gowa should combine westward dust and nuisance control, shade-oriented thermal mitigation, moisture-resilient design, passive ventilation, and microclimate monitoring. Novelty/Originality of this article: The article converts a local environmental baseline into an internationally structured planning approach by integrating windrose exposure, Beaufort classification, and tropical microclimate parameters into practical recommendations for peri-urban residential development.
