Green open spaces: climate mitigation of climate change in Indonesia

Introduction: The provision of microclimate for young people is an important prerequisite for outdoor thermal comfort in urban communities. The microclimate consists of four elements: air temperature, humidity, wind speed and solar radiation. The City Green area consists of urban landscape, urban forest green, urban recreational green, sports green and garden green. The green open spaces are classified according to the state of the region, not according to the shape or structure of the vegetation. The green land is intended to maintain land availability as a catchment area. Methods: in this study the authors tried to use a systematic literature review method. This method tries to collect existing literature and articles which are then reviewed to look for potential green open spaces as a solution to addressing microclimates. Finding: In the early 1990s, the United Nations Framework Convention on Climate Change (UNFCCC) was established as the body to address global warming: mitigation and adaptation. Mitigation involves finding ways to slow, control or absorb greenhouse gas emissions from forests or other carbon "sinks". In response to global warming and climate change, the Government of Indonesia enacted Law No. 26 in 2007. Law No. 05/PRT/M/2008 on Spatial Planning and the Guidelines of the Minister of Public Works on the Provision and Use of Green Open Space in Urban Areas stipulate that green open space is defined as space that extends/expands and/or clusters, which is more open for human use, and is a place for plants to grow, both naturally and intentionally planted. Conclusion: Benefits of green space include supporting the health, welfare and safety of urban residents. Green spaces can also promote the production of natural resources, prevent natural disasters, protect the environment, promote health and safety, and promote entertainment activities and map development

The Effectiveness of green belt vegetation in reducing air pollution and noise

Introduction: Urbanization, industrial growth, and heavy traffic are driving a rise in air and noise pollution in cities, posing serious threats to public health and environmental sustainability. Airborne particulates can trigger respiratory and cardiovascular conditions, while chronic exposure to high noise levels impairs mental well-being, sleep, and hearing. As a response to these challenges, green belts—vegetated buffer zones—are increasingly recognized for their dual function in mitigating pollution and enhancing urban livability. Methods: This study assessed the environmental performance of three tree species—Moquilea tomentosa Benth, Litsea garciae, and Khaya anthotheca—in reducing air pollutants and noise levels. Data was collected by measuring dust retention per tree and comparing noise intensity between greenbelt and open areas. The pollution capture was analyzed through quantification of particulate deposition, while noise reduction was observed using decibel level comparisons.  Findings: Among the species tested, Khaya anthotheca demonstrated the highest dust-absorbing capability with 501.86 g/tree, followed by Litsea garciae (338.07 g/tree) and Moquilea tomentosa Benth (141.57 g/tree). In terms of acoustic performance, greenbelt areas showed a noise reduction of approximately 16 dB, compared to only 11 dB in non-vegetated spaces. These outcomes highlight the superior pollution-mitigation benefits of certain tree species, particularly when strategically integrated into urban green infrastructure. Conclusion: These findings affirm the vital function of green belts in urban pollution control. The study emphasizes that the strategic selection of tree species and thoughtful planting design can significantly enhance the effectiveness of green infrastructure in improving air quality and reducing environmental noise in city landscapes. Novelty/Originality: The novelty of this study lies in its comparative evaluation of specific tree species for their dual ability to mitigate both air and noise pollution in urban environments—a topic that is often studied separately but rarely in a combined context

The role of vegetation in enhancing thermal comfort in open spaces: a study on the impact of temperature and humidity

Introduction: Thermal comfort in outdoor urban spaces is largely shaped by microclimatic elements like air temperature, humidity, and wind speed, all of which are strongly influenced by vegetation. This study investigates how vegetation, especially tree canopies and vegetative cover, affect microclimate regulation and contributes to thermal comfort in urban settings. Methods: The research was carried out at the IPB Arboretum on August 28, 2024, using observational techniques over a three-hour timeframe. Tools such as a digital thermohydrometer and a mini weather station were employed to measure temperature, humidity, and wind speed, while vegetation mapping was used to classify canopy density.  Findings: The analysis found that trees like Ficus benjamina can significantly lower air temperature and raise humidity beneath their canopies through processes such as evapotranspiration and interception of solar radiation. Areas with dense, overlapping canopies were observed to have noticeably cooler and more humid conditions, while areas with minimal vegetation showed characteristics typical of the Urban Heat Island (UHI) phenomenon. However, statistical regression did not reveal a significant correlation between canopy cover percentage and temperature or humidity, implying that other variable—like human presence or surface materials—may also play important roles. Conclusion: These results underline the ecological value of vegetation in moderating urban microclimates. Although canopy density alone may not directly correlate with climate indicators, strategically placing vegetation in city planning remains crucial for reducing heat stress and improving environmental quality in urban open spaces. Novelty/Originality: The novelty of this research lies in its focused examination of how specific tree species and canopy densities influence thermal comfort in an urban arboretum setting, using real-time, on-site environmental measurements
