Mitigation Hierarchy

The increased urbanization and human population growth of the recent decades have resulted in the loss of urban green spaces. One policy used to prevent the loss of urban green space is ecological compensation. Ecological compensation is the final step in the mitigation hierarchy; compensation measures should thus be a last resort after all opportunities to implement the earlier steps of the hierarchy have been exhausted. Ecological compensation should balance the ecological damage, aiming for a “no net loss” of biodiversity and ecosystem services. In this study, we develop a simple model that can be used as tool to study the welfare effects of applying ecological compensation when green space is at risk of being exploited, both at an aggregate level for society and for different groups of individuals. Our focus is on urban green space and the value of the ecosystem service—recreation—that urban green space provides. In a case study, we show how the model can be used in the planning process to evaluate the welfare effects of compensation measures at various sites within the city. The results from the case study indicate that factors such as population density and proximity to green space have a large impact on aggregate welfare from green space and on net welfare when different compensation sites are compared against each other.

Process Of Urbanization

During the process of urbanization, many green spaces are fragmented for other uses. The key problems for researchers and planners are reducing the fragmentation of green spaces, constructing urban ecological networks, and maintaining sustainable environments to cope with the rapid urbanization process. This paper analyzes Fuzhou, China as a case study of the effects of urbanization, and reviews three epochs in Fuzhou: 2000, 2010, and 2021. First, the integration degree of landscape pattern index and spatial syntactic attribute value is used to quantify the urbanization situation of Fuzhou and the degree of green space fragmentation in the process of urbanization. Second, it adopts the network analysis method to construct an urban ecological network featuring “one city and two rings”. Finally, urban green spaces are assessed by the corridor structure analysis, and the improvement of the urban green space ecological network is quantitatively evaluated by comparing the green space ecological network with the green space planning system. The results show that the urbanization of Fuzhou city center is apparent and the fragmentation of urban green space is a serious issue from 2000 to 2021. The green space planning in Fuzhou is ineffective in improving the existing green space. According to the results, the street integration of space syntax aptly reflects the process of urbanization. In conclusion, the planned ecological network increases the shape complexity of green patches and landscape connectivity and reduces landscape fragmentation, thus improving the urban ecological environment quality and facilitating the sustainability of urban green spaces.

<p><strong>Abstract.</strong> Parks and other public green spaces (hereafter “urban green spaces”) provide many benefits to urban dwellers, but some residents receive few benefits due to a lack of urban green spaces nearby their home/workplace. Understanding spatial variations in urban green space accessibility is thus important for urban planning. As a case study, here we mapped urban green space accessibility in Japan’s highly urbanized Tokyo and Kanagawa Prefectures using a Gravity Model (GM). As the inputs for the GM, we used georeferenced datasets of urban green spaces obtained from various sources, including national government (Ministry of Land, Transportation, Infrastructure, and Tourism; MLIT), a commercial map provider (ESRI Japan Corporation), and a crowdsourcing initiative (OpenStreetMap). These datasets all varied in terms of their spatial and thematic coverage, as could be seen in the urban green space accessibility maps generated using each individual dataset alone. To overcome the limitations of each individual dataset, we developed an integrated urban green space accessibility map using a maximum value operator. The proposed map integration approach is simple and can be applied for mapping spatial accessibility to other goods and services using heterogeneous geographic datasets.</p>

This paper presents the results of an assessment of change in urban green spaces in Thanh Hoacity (Vietnam). Sentinel 2 MSI data in 2015 and 2021 are used to calculate 3 parameters: percentage ofgreen, weight of green types, and weight of proximity to green. These parameters are used to calculate theWeighted Urban Green Space Index (WUGSI). The final result shows the distribution of green space inthe study area consisted of very high-quality green, high-quality green, moderate quality green, and lowquality green. The obtained results show that the quality of urban green space in Thanh Hoa city haschanged significantly in the period 2015-2021, in which the area with category “low quality green space”increased from 7.17% up to 9.48%; areas with category “very high-quality green space” reduced from65.02% to 47.39%.

The City

Urban green spaces are intended to provide citizens with calm environments free of annoying city noises. This requires a thorough understanding of noise emission and related exposure to sounds in green spaces. This research investigates noise perception in various spots in an urban green space. For this purpose, the study has been conducted in the grand garden of the city of Dresden. The garden covers 1.8 square kilometers of various landscapes, including water streams, park railways, fountains, bridges, roads for bicycles and pedestrians etc. Noise perception was investigated at eleven spots with emphasis on four noise types: nature noise, human noise, traffic noise, and technical noise. In parallel, audio-visual recordings were conducted for each spot to identify the connection between the perceptual measures and the psychoacoustic parameters. These spots are categorized based on the resulting perception and psychoacoustic parameters. In addition, the visual effect of each spot on final perception is investigated. Eventually, annoyance for each spot is identified based on the corresponding participants' perception and is associated with the relevant psychoacoustic parameters.

The Relationship

ABSTRACT Urban area is dominated by land that  functioned  of  the  interest of  economy and  settlement,  but only a few land allocated for wildlife. The butterflies was one of the wildlife that could be found         in urban areas.The remaining habitat that can be used by butterflies assumed confined to the urban green space. Based on its life cycle, the butterflies having an initial phase (egg to larvae) is a phase which is generally require specific habitat. This research aims to determine the relationship between landscape characteristic and oviposition site preferences of butterfly. This research was conducted on April to June, 2014 at fifteen urban green spaces in East Jakarta by using descriptive survey technique. Landscape characteristics measured include area, perimeter, lawn area, closed vegetation area, open vegetation area, non vegetation area. Landscape characteristic not only measured from urban green space, but also measured from the area around urban green space within the scope of 100 meters  buffer. Results show that there is a relationship between landscape characteristic and oviposition site preferences. Significant positive correlation between the abundance and area correlation coefficients   rs (0,546), open vegetation area rs (0,758) and non vegetation buffer area rs (0,688). There was no significant correlation between the abundance with perimeter area,  lawn  area,  closed  vegetation  area,  non vegetation  area,  lawn  buffer,  open  vegetation  buffer  and  closed  vegetation  buffer.   Keywords: caterpillar,landscape characteristic, oviposition site, preferences, urban green space

Big City

The appearance of different urban green space phenomena occuring both in developing and developed countries appeals to be found out in research. Urban green space hasn’t been an essential element in developing countries, such as in Indonesia and its big city. In another part, precisely in Lyon, urban green space is considered as an intergral and important part of city development, particularly in last 24 years (begun in 1990’s). Moreover, their people actively participate in some urban green space projects and go frequently in urban green spaces or urban parks. By indentifying those two phenomena, it’s vividly seen a problem both in societal and municipal level. Based on those facts, this research tried to find out a research question which is about the importance of urban green space for society and minicipality. This research that has been conducted in Tête d’Or park, gerland park, Sergent Blandan park, the river bank of Saône and Rhône as well as Mazagran park, used qualitative methode with some interviews reserved to some key actors, including society. The result shows that society regards urban green space as a source of benefit for social, education and health. Whereas, municipality considers it as an integral element of city providing environmental and economic benefit for city.
