Abstract

The Palopo City watershed could not accommodate the high discharge of rainfall that had fallen previously. The Green Open Space (GOS) had an ecological function by absorbing rainwater. Urban green open spaces absorbed surface flow water in the past, reducing the risk of flooding. In the past, this research measured the effectiveness of three green open spaces (Islamic Center, Pancasila Field, and Salubulo Field) in reducing flooding in Palopo City. We collected data on vegetation types, infiltration capacity, and runoff discharge. Data analysis involved the analysis of infiltration capacity (F), runoff discharge (Q), and green open space effectiveness. In the three green space locations, the following vegetation types were found: Katapang (Terminalia catappa), Palm (Dypsis lutescens), Trambesi (Samanea Saman), and Grass (Cyperus rotundus). The highest total infiltration capacity in the Salubulo Field Green Space resulted in 155 m3/hour (fast category). In the past, the most significant runoff discharge's total value was GOS Pancasila Field: 713.4 mm3/minute. The study concluded that the Salubulo Field Green Space had the highest infiltration capacity (160 m3/hour) and runoff discharge (69 mm3/minute), making it the most effective in reducing flooding in Palopo City in the past. This was > 1 (effectiveness criteria achieved), and the space was dominated by vegetation (trees and grasses).

Abstract

The mangrove ecosystem is one of the many ecosystems found along tropical beaches that have a function as a buffer area between land and sea and produce organic matter. There are several factors that influence the spread of mangrove plants, namely the physical factor of the soil. This study aimed to determine the soil carbon content in the mangrove ecosystem in the village of Temmalebba, South Sulawesi. The data collected in the form of bulk density (BD), organic matter (BO) and percent C for analysis of carbon content was obtained from the analysis of soil samples taken from 10 points with 3 replications for composite samples. The sampling point was determined based on the growth and density of mangroves. Furthermore, the data was analyzed using the organic C equation and carbon content. The results showed that the highest bulk density was found at a depth of 60–100 cm with a value of 1.28 g/cm3. The highest percent of organic matter content found at a depth of 0-30 cm with a value of 9.18%. The highest soil carbon content found at a depth of 60–100 cm with a value of 225.38 (MgC ha-1). Soil carbon content in the mangrove ecosystem of Bone Bay, Temmalebba village is strongly influenced by several factors, including soil depth, bulk density, organic matter, and soil texture.

Abstract

Green open space (RTH) plays an essential role in climate change mitigation through its capacity to absorb and store carbon. Palopo City, which has experienced rapid urban growth, requires scientific data on carbon storage potential in its green open spaces. This study aimed to analyze carbon storage potential and the economic value of carbon in RTH vegetation in Palopo City. The research was conducted in selected RTH areas across nine districts using a non-destructive sampling method and allometric equations. Vegetation biomass was estimated from tree diameter measurements and converted into carbon storage and CO₂ absorption. Carbon economic value was calculated using carbon pricing estimates of USD 5–10 per ton. The results showed that total carbon storage in Palopo City’s RTH reached 9,094.93 tons/ha, with the highest value found in the Salubulo Islamic Cemetery RTH, North Wara District. This location also exhibited the highest carbon economic value. These findings highlight the strategic role of urban green open spaces in climate change mitigation and sustainable urban development).
