Surakarta City's population is growing every year, putting pressure on the land and vegetation. Surakarta City has a population of 500,173 people in 2010. The population of this city is growing every year, driving an increase in the demand for land and living facilities. This study aims to analyze the availability of vegetated land as urban green space, and calculate the 5-year (2010–2015) vegetation cover changes. The methods used visual interpretation and on-screen digitization of the image Landsat 7 ETM+ satellite in 2010 and Landsat 8 OLI satellite image in 2015. The results show that the availability of vegetated land as urban green space in Surakarta City is lower than that mandated in Law Number 26 of 2007 concerning Spatial Planning. Vegetation cover decreased from 2010 to 2015 in Surakarta City, covering an area of 117.7 ha (2.6% of the city area) or an average of 23.5 ha (0.5%) per year. Research on the availability of green open spaces on a regular basis is expected to be part of the process of monitoring and evaluating urban development and as input for local governments in the decision-making process.

Study Results

This paper presents the analysis of the effect of urban green space types on land surface temperature in Hue city. Data are collected with temperature monitoring results from each green space type and the interpretation of surface temperature based on Landsat 8 satellite image data to determine temperatures at different times of the year. Results showed that there was a significant correlation between types of urban green space and the surface temperature. Types of green space with a large area and vegetation indexes have a greater effect on temperature than areas with a smaller green space do. Green space types including forest green space, dedicated green space and agriculture green space have the most effect on the surface temperature. The forest area has the greatest influence on the temperature with a temperature difference of more than 1.6 degrees Celsius at 9:00 in the daytime. Besides, the results extracted from satellite images also show that the area of urban green space going to be reduced makes a contribution to increase the surface temperature of urban areas. The study results have established foundation for planning the green spaces in climate change challenges in Hue City.

<p><strong>Abstract.</strong> Urban Green Space (UGS) enhances the structure of the landscape of a city. It provides economic, social and health benefits to the inhabitants. Rapid urbanization and increase in population has put extreme pressure on urban green spaces. Therefore, mapping of urban green spaces is important to facilitate the urban planning sustainably. This study has been taken up to map the UGS in the Hisar Municipal Corporation (HMC) area of Haryana State constituting an area of 4197.32<span class="thinspace"></span>ha using high resolution LISS-IV data of November, 2017. Three different methods namely (a) Onscreen Digitization (b) Support Vector Machine-based classification (SVM) and (c) Multi Resolution Segmentation (MRS) have been tested to extract the green spaces. The onscreen digitization method has been considered as best method as compared to SVM and MRS because of the intervention of human mind and full control on manual editing. The SVM under estimated the green space for HMC with average relative deviation of 15%. However, it extracted the green area precisely without mixing of open spaces. MRS have given good results in terms of total area (relative deviation was 5%), however, spatial distribution of green spaces have been mixed with open spaces. The study identified the green index of HMC and suggested the suitability and sustainability of the city based on World Health Organization (WHO) defined standards. Green space for Hisar Municipal Corporation was 1690.96<span class="thinspace"></span>ha with average urban green space index of 0.40. Per capita green cover for HMC was 9.69<span class="thinspace"></span>m<sup>2</sup>/inhabitant, which is as per the standard reported by WHO i.e. 9<span class="thinspace"></span>m<sup>2</sup>/inhabitant. Further study may suggest some other algorithm for better results and automatic green space extraction.</p>

The City

Urban Green Space Development has become a challenging task for city governments especially in Indonesia, due to high prices of land around urban centers. On the other hand, there are inconsistencies between land use and land allocation within the city planning. In Surabaya City, quite a lot of gas stations were built on areas which are originally intended for green open spaces. Surabaya City Municipality is strongly committed to reconvert Gas Station Areas to green open spaces as determined in the plan. Innovative strategies have enabled the city government to reconvert 13 gas stations to public parks. This paper analyzes the implementation process of the Urban Green Space Reconversion Policy, describing the historical details of the issues, the  taking over of land from gas station owners, and the park development and campaigning. Discussion also includes the most influential factors in this success story.

The Impact

Urbanization continues to trigger massive land-use land-cover change that transforms natural green environments to impermeable paved surfaces. Fast-growing cities in Asia experience increased urban temperature indicating the development of urban heat islands (UHIs) because of decreased urban green space, particularly in recent decades. This paper investigates the existence of UHIs and the impact of green areas to mitigate the impacts of UHIs in Colombo, Sri Lanka, using UrbClim, a boundary climate model that runs two classes of simulations, namely urbanization impact simulations, and greening simulations. The urbanization impact simulation results show that UHIs spread spatially with the reduction of vegetation cover, and increases the average UHI intensity. The greening simulations show that increasing green space up to 30% in urban areas can decrease the average air temperature by 0.1 °C. On the other hand, converting entire green areas into urban areas in suburban areas increases the average temperature from 27.75 °C to 27.78 °C in Colombo. This demonstrates the sensitivity of UHI to vegetation cover in both urban and suburban areas. These seemingly small changes are average grid values and may indicate much higher impacts at sub-grid levels.

The provision of land to build green open spaces in urban areas as in the city of Yogyakarta is important considering that the increasing activities of urban communities will cause various environmental problems, such as an increase in vehicle smoke pollution, a decrease in the quality and quantity of groundwater, flooding, and so on. This study aims to determine how the implementation of land acquisition for the construction of public green open space in Yogyakarta City and the obstacles that arise in land acquisition for the construction of public green open space. This research is a type of empirical juridical research, which begins with understanding the legal rules or norms governing green open spaces in urban areas. Because of the limited land available to build this Public Urban Green Space, what the Yogyakarta City Government does is one of the ways to acquire land to build Public Urban Green Space is to buy people's land as allowed in the Land Acquisition Law and its implementing regulations.

Urban Thermal Environment

Land use/land cover (LULC) pattern change due to human activity is one of the key components of regional and global climate change drivers. Urban green space plays a critical role in regulating urban thermal environment, and its cooling effect has received widespread attention in urban heat island (UHI) related studies. To fully understand the effects of the landscape pattern of an urban green space in regulating the urban thermal environment, it is necessary to further study the thermal effects of the landscape pattern of the urban green space and its characteristics under varied spatial–temporal scales. In this paper, we took the urban core area of Hangzhou City as the study area and analyzed the relationships between the landscape metrics of the urban green space and land surface temperature (LST) under varied spatial scales by using correlation analysis and redundancy analysis (RDA) methods. Multi-temporal Landsat 8 thermal infrared sensor data were used to retrieve the spatial and temporal dynamics of LSTs in four consecutive seasons, and the land use classification was interpreted using SPOT (Systeme Probatoire d’Observation de la Terre) satellite imagery. The results showed that landscape dominance metrics—e.g., percentage of landscape (PLAND) and largest patch index (LPI)—were the most influential factors on urban LST. The spatial configuration of urban landscape, as represented by the fragmentation and aggregation and connectedness, also showed significant effects on LST. Furthermore, landscape pattern metrics had varied spatial scale effects on LST. Specifically, the landscape dominance metrics of urban forest showed an increased influence on LST as the spatial scale increased, while for urban water, the trend was opposite. These findings might have some practical significance for urban planning about how to spatially arrange urban green space to alleviate UHI at local and regional scales.

Aims: The need for studies from more countries on the relationship between urban green space and health has been emphasized. The aim of this study was to investigate the association between two types of measurement of urban green space and self-reported lifestyle-related disorders in Oslo, Norway. Methods: Self-reported measures on mental disorders, asthma, type 2 diabetes and musculoskeletal pain of 8638 participants in the Oslo Health Study (HUBRO) were linked to two types of green space variables: the vegetation cover greenness derived from satellite data, which shows the city’s vegetation cover regardless of property boundaries, and the land use greenness derived from municipal plans showing information about publicly accessible vegetation-covered areas. Associations between greenness and health measures were analysed by logistic regression models controlling for possible individual and contextual confounders. Results: Increasing vegetation cover greenness was associated with fewer self-reported mental disorders for both men and women after controlling for possible confounders. The proportion of women who reported high levels of musculoskeletal pain increased with increasing degrees of both of the greenness measurements, but no significant association was observed for men. No association was found for asthma and diabetes type 2 for either men or women. Conclusions: Although there was a positive association between vegetation cover greenness and self-reported mental disorders, the main findings showed mixed results. The lack of clear associations between urban green space and lifestyle-related health disorders in Oslo might have been influenced by a large proportion of the inhabitants having easy access to green areas.

Urban green space (UGS) has been proven to be essential for improving the health of residents. Local governments thus need to provide attractive UGS to enhance residents’ wellbeing. However, cities face spatial and finanical limitations in creating and managing UGS. As a result, greening plans often fail or are postponed indefinitely. To evaluate whether informal urban green space (IGS) can supplement existing UGS, we conducted a questionnaire survey of 567 residents in Ichikawa (Japan), a city currently providing only 3.43 m2 green space per capita. In particular, we analyzed how residents’ existing green space activities affect IGS perception, as it may be difficult to recognize IGS as greenery because it is not an officially recognized space for recreation. Results show that residents took a favorable stance towards IGS, but perception differs depending on their green environment exposure. Residents who are frequently exposed to green environments in their daily lives highly recognized the environmental improvement aspects of IGS and significantly perceived spatial accessibility as an advantage of IGS. Willingness to participate in conservation activities of UGS was linked with a likelihood of recognizing IGS as UGS. Our results encourage understanding IGS as supplementary green space taking into account the attitude of residents to UGS, and contribute to introducing the IGS discourse into green space planning.
