How perception of environmental and social justice drive citizen's satisfaction and intention to engage with urban forests management?

With the expansion of urbanization, urban structures are changing. In recent decades, increasing attention has been paid to the maintenance and expansion of green spaces. Urban forests, as highly natural multifunctional structures, effectively meet human needs for environmental and social ecosystem services while requiring significantly fewer resources for maintenance compared to parks and landscaped areas. Latvia is rich in forests that have been historically preserved in urban and suburban areas. To assess the management situation of urban forests, six cities rich in urban forests were selected: Riga, Jurmala, Daugavpils, Jelgava, Liepaja, and Ogre. According to European experience, urban forest management is characterized by integration, long-term management strategies, multidisciplinary approaches that go beyond forestry activities, and the involvement of various stakeholders. The authors propose a definition of urban forests specific to Latvia and outline their main functions—social, environmental, educational, nature conservation, aesthetic, and economic. In addition, key challenges and problems were identified based on the opinions of ten experts in urban forest management. The aim of this article is to evaluate approaches to urban forest management in Latvia and to provide recommendations for improving urban forest management. Field studies of forest areas in six cities were conducted, meetings with experts were held, available statistical data on forest areas were analyzed, and municipal and management company strategies, forest management plans, and other relevant information were reviewed. The study compiled and analyzed urban forest areas, their distribution within cities, specially protected areas, forest parks, dominant tree species, forest landscape characteristics, and the potential of natural resources for recreation Recommendations were made: to develop an understanding of urban forest functions, to define and identify areas critical to these functions, and to recognize them in the field. Urban forest managers should consider a wide range of knowledge, not limited to forestry, encourage collaboration between stakeholders, and educate the public. It is important to improve recreational areas, implement zoning of maintenance intensity to reduce anthropogenic pressure, ensure accessibility, preserve natural values, and enhance resilience to climate change. It is also essential to update legislation on urban forest management to reflect current conditions.

Sustainable management and conservation of urban forests are becoming increasingly important to achieve urban sustainability, thus requiring a unified stakeholder collaboration at different levels. Local communities and youth play essential roles in sustainable urban forest management. This study analyzed the institutional arrangement for urban forest management in Ghana and the involvement of local communities and youth. The research involved an in-depth analysis of environmental institutions in Ghana and used qualitative methods to explore community and youth roles in urban forest management. Findings revealed a lack of a specific institution spearheading urban forest management, leading to overlapping responsibilities and administrative conflicts. Despite their potential, local communities and youth are often excluded from urban forest planning and management, resulting in decreased ownership and misuse of urban forests. Recommendations include assigning clear roles to responsible institutions, designating a specific urban forest management body, and adopting a youth-focused participatory approach for effective management.

IntroductionThere is a growing demand for urban forest management that prioritizes genuine community involvement, acknowledges power imbalances within society, and embraces the principles of environmental justice. To assess current initiatives and share better/best approaches, examining how environmental justice principles are applied in urban forest planning and practice is crucial. This study aims to understand the perspectives of urban foresters on the factors that either facilitate or impede the attainment of environmental justice goals.MethodsInterviews were conducted with urban foresters from non-profit organizations and municipal government in San Francisco, California, and Seattle, Washington. The interviewees were asked to identify and discuss their tree planting and maintenance strategies, public engagement protocol, and inter-organizational collaboration processes. To provide a contextual understanding of environmental injustice in the study cities, the historical racist practice of neighborhood redlining was examined alongside current tree canopy cover, locations of environmental hazards, and the spatial distribution of persons of color and those living in poverty.ResultsThe findings revealed that urban forestry professionals in each city approached environmental justice in distinct yet complementary ways: San Francisco prioritized distributional justice, while Seattle focused on elements of procedural and recognitional justice. The Race and Social Justice Initiative in Seattle and Proposition E in San Francisco have been instrumental in identifying and addressing inequities in urban forest planning and practice.Discussion/conclusionCreating fair and inclusive urban forestry practices that prioritize disadvantaged neighborhoods has been a difficult task for both cities. Acknowledging and addressing past policies and cultural perspectives that have led to marginalization is crucial for building trust with these communities. Moving forward, prioritizing recognitional justice in urban forest planning and management should be a top priority.

Urban forests contribute to social, aesthetic and economic benefits within cities. In urban forest management, these aspects are often not incorporated, especially in the countries of South East Europe (e.g. Serbia), where the management of urban forests is still dominated by classical forestry aims (i.e. timber production). This paper analyzes the Ko utnjak urban forest in Belgrade, with a special emphasis on the needs of its visitors and the importance of its use. We aim to raise awareness of the social benefits that this urban forest provides to residents and offer suggestions for sound and responsible management, which are based on the assumption of active and regular involvement of visitors. This case study contributes to a better understanding of visitors relationships with this urban forest, which is an important urban forest at the country level. Visitors of this urban forest completed a face-to-face survey, which indicated that most of the visitors came from surrounding neighborhoods, mainly for active recreation (engaging in sports) and relaxation in the forest. Most of respondents were satisfied with the management and maintenance of the area. Nevertheless, they offered suggestions for improvements. Most of the visitors would be willing to get personally involved in a decision-making process regarding the area and showed a willingness to pay money toward the maintenance via fees. Thus, this study demonstrates the potential and need of public involvement in the management of such urban forests. The findings indicate that this approach could help decision makers express commonly shared values in management decisions.

Abstract. Aulia R, Kaswanto, Arifin HS, Mosyaftiani A, Syasita N, Wahyu A, Wiyoga H. 2023. Assessing the benefits and management of urban forest in supporting low carbon city in Jakarta, Indonesia. Biodiversitas 24: 6151-6159. Climate change is a phenomenon that has become a global concern including in urban areas. Jakarta is one of the most populated cities in Indonesia, reaching 10.56 million people in 2020 with high emissions levels due to high human activities. Thus, efforts to reduce carbon emissions to mitigate climate change are necessary in Jakarta one of which is through the concept of low carbon city and manifested in the establishment of Green Open Space (GOS), including urban forests. Urban forests aim to sequester and store carbon, and improve the urban microclimate. This research aimed to assess the benefits of urban forests in Jakarta in term of their capacity in carbon sequestration using i-Tree Eco tool, and analyse the management of urban forests related to the applicable regulations. To collect data on trees, this study created 49 plots scattered across Srengseng Urban Forest, Cipayung Urban Forest, Munjul Urban Forest, Rawa Malang Urban Forest, and Pondok Labu Urban Forest. Tree species, Diameter at Breast Height (DBH), total tree height, live tree height, crown base height, crown width, percent crown loss, and crown light exposure were all gathered. Furthermore, in-depth interviews with urban forest managers were performed to gather additional information on present management, including questions derived from Jakarta's green open space legislation to assess management efficacy. The results of the analysis of urban forest quality show that the health status of trees is one of the factors that indicate the quality of urban forests at the five study sites, with more than 50% of the total trees in fair condition (75- 90% health). The gross carbon sequestration of trees in five urban forests Jakarta is about 184.8 metric tons of carbon per year. Additionally, the in-depth interviews also test the mortality of the urban forest, a decent indicator of current management with estimates over the next 10 years, showing a slight increase in carbon sequestration and storage capacity. However, the mortality scenario leads to a trend toward a decrease in leaf area and the number of tree categories, especially in the Srengseng Urban Forest.

Urban forest management has a strategic role in maintaining ecosystem balance and supporting the quality of life of urban communities. Urban forests provide various ecosystem services, such as providing clean air, temperature regulation, carbon storage, and being a habitat for biodiversity. In the midst of increasing urbanization and climate change, the existence of urban forests is increasingly important to support environmental sustainability. However, public awareness of the importance of urban forests and the ecosystem benefits they provide is often inadequate. This is a challenge in efforts to conserve and develop urban forests as an integral part of the urban environment. Palangkaraya City, Central Kalimantan, the Himba Kabui ecotourism program has been launched as an initiative to increase public awareness of urban forests and the ecosystem benefits, they provide. This research aims to analyze the role of stakeholders and artificial intelligence (AI)-based urban forest management strategies in improving public awareness of urban forest ecosystem services and their impact on the success of the Himba Kabui ecotourism program in Palangkaraya City, Central Kalimantan. Stakeholders involved include government, local communities, the private sector, and academia, each of which has an important role in the implementation and development of this program. The use of AI in urban forest management offers various innovations in monitoring, decision making, and conveying information to the public. This study found that the integration of AI technology was able to accelerate increasing public awareness of the importance of urban forests as providers of ecosystem services, such as providing clean air, climate regulation and biodiversity habitat. Additionally, this increased awareness contributes significantly to the success of the Himba Kabui ecotourism program, which aims to promote sustainable tourism and environmental conservation in the region. This research provides the implication that synergy between stakeholders and AI technology can become an effective and sustainable urban forest management model, which not only has a positive impact on the environment but also on the local economy through increasing tourism. It is hoped that these findings can become a reference for urban forest managers and policy makers in developing innovative and participatory environmental management strategies.

Urban forest is one of few alternatives to balance the deterioration in the quality of environment. Jakarta has 14 urban forests under the coordination of the Department of Marine and Fisheries. In contrast, there is also urban forest located in South Jakarta and managed by local community to provide not only for preserving environment but also providing social life for local inhabitants. This paper aims to analyze the roles of community in the urban forest management. In addition as a city buffer, urban forest is also have an immense economic potential to improve the well-being of local community. The case of urban forest described in this paper is Sangga Buana located at Lebak Bulus, South Jakarta. Through observations, in-depth interviews, and focus group discussions, it is found that the responsibility in managing urban forest depends not solely on the government but also on the community. The Sangga Buana urban forest is one of examples where the local community practically has managed the forest. Since the very first time this urban forest was developed, the contribution of the government in the development of this site is almost unheard. This lack of support, however, initiates the local community to manage and develop the forest. The roles of local community in the urban forest management are arranged as a long-term participation. As such, the local community is transformed from merely a passive stakeholder of urban forest to active management of it. The forest now functions not only as a buffer to prevent floods and drought, but also provides economic benefits for the local community. In this sense, this urban forest has appeared as embodiment of the concept of sustainable green environment. Keywords: urban forest, Sangga Buana, role of community, green environment, Jakarta

However, the urban forest structure, function and role in carbon(C) offsets of Chinese urban forests are little understood. The main objective of this study was to evaluate the C storage and sequestration by urban forests and C emissions from energy consumption by urban energy consumption in Guangzhou, and analyse the effect of urban forests offsetting the C emissions from energy use. This paper also discussed the relationship between urban low carbon development and forest C sink, and explored the management practices for improving Guangzhou's urban forest function of offsetting C emissions. Guangzhou is located in north side of the Pearl River, along southeastern coast of China. The forests in Guangzhou includes five main types: Eucalyptus, Plus massoniana, Cunninghamia lanceolata, economic forest and evergreen broad-leaved forest. C storage and sequestration were quantified using urban forest inventory data and by applying volume-derived biomass equations and other models related to net primary productivity (NPP). C emissions from urban energy use were estimated by accounting for fossil fuel use and C emission factors. Total C storage by Guangzhou's urban forests was estimated at 654.42×104 t, and average C density was 28.81 t/hm2. C storage in different districts ranged from 1.50×104 t to 354.99×104 t, as in the following order: Conghua>Zengcheng>Huadu>Baiyun>Luogang>Panyu>Tianhe>Huangpu. C storage of evergreen broad-leaved forest and young age class forest were respectively 530.67×104 t and 271.86×104 t, which had played a chief role in forest total C storage in terms of forest type and age class. C sequestration by urban forests was 658,732 t/a, with an average C sequestration rate was 2.90 t·hm-2·a-1. The spatial distribution of C sequestration in Guangzhou was imbalanced: most of C was sequestrated in exurb just like Conghua and Zengcheng. The C sequestration percentages of Eucalyptus, Plus massoniana, Cunninghamia lanceolata, economic forest and evergreen broad-leaved forest were 6.25%, 8.13%, 3.67%, 1.48% and 82.25% respectively. C sequestration rate decreased with increasing forest age. For Eucalyptus, C sequestration for young, middle-aged, premature, mature and post-mature forests decreased with age from 3.06 t·hm-2·a-1 to 2.35 t·hm-2·a-1. Results were similar for Plus massoniana which decreased from 1.99 t·hm-2·a-1 to 1.34 t·hm-2·a-1, for Cunninghamia lanceolata from 4.06 t·hm-2·a-1 to 2.61 t·hm-2·a-1, and for evergreen broad-leaved forest from 4.17 t·hm-2·a-1 to 3.68 t·hm-2·a-1. Average annual C emissions of urban energy use from 2005 to 2010 in Guangzhou were 2907.41×104 t. Therefore, the C stored by urban forests equaled 22.51% of the average annual C emission from fossil fuel use, and C sequestration could offset 2.27% of the average annual C emission in Guangzhou. Urban forest's C sequestration had a small contribution on urban carbon reduction, but it is still one of the important measures of low carbon development from its comprehensive benefits such as releasing Oxygen, air purification, VOC(volatile organic compounds)management, stormwater runoff capture, building energy saving, aesthetics and recreation. Furthermore, this paper also analyzed the impacts of forest composition and forest age structure on C storage and sequestration of urban forests in Guangzhou, and gave suggestions on improving forest C sink to enhance C offset effect through the forest management. 参考文献 相似文献 引证文献

Adopting public values and climate change adaptation strategies in urban forest management: A review and analysis of the relevant literature

Urban forests are an instrument of urban ecosystems, their existence is very important in the midst of declining environmental quality in urban areas, besides that urban forests also have various environmental service functions such as being able to absorb CO2 content, as an oxygen supply, then urban forests also have economic value. The policy on urban forest management is important so that its sustainability is maintained. Therefore, this study aims to analyze urban forest policies in forest management. This research was conducted in Serang City. This research approach uses the ANP (Analysis Network Process) approach, involving respondents from the Government (Regional Government Development Agency and Environmental services), forestry academics, forest researchers, KLHK employees in the forestry sector, practitioners engaged in forestry and environmental non-governmental organizations. The results of this study that from the three levels analyzed are factors, actors, and alternatives. The results from the level factor (policy support, quality improvement, evaluation and monitoring) show that policy support is the most priority thing. Meanwhile, from the level of actors (Government, Community, Private, government and private, NGOs) shows that the most influential actor in urban forest management is a combination of government and private sector. Then at the alternative level (evaluation of regulations, selection of tree species, expansion of urban forests, incentives, and sanctions) shows that the expansion of urban forests is the most important thing to implement.

Municipalities across the United States have varied available resources to manage urban forests, resulting in substantial differences in urban forestry services and outcomes. This article reviews 32 survey-based studies that characterize U.S. municipal urban forest management program dimensions, including program components; needs and barriers; knowledge of and attitudes toward urban forests; and plans and priorities for future management. Such information is critical for agencies that support local urban forest management efforts but has not previously been systematically gathered and condensed. Based on the limited national, regional, and state-level data published in peer-reviewed journals, we find that the number of municipal urban forestry programs appears to be increasing, many communities have at least one tree ordinance, and larger communities are more likely to have an official program. However, evidence suggests that few municipalities have an urban forest inventory or management plan, and most require additional financial, political, public, or educational support. More research on urban forestry program status, needed support, and local knowledge is needed as knowledge gaps remain regarding the influence of metropolitan areas and resident demographics on the presence and extent of municipal urban forestry programs. Additionally, few studies have investigated future municipal urban forestry-related intentions and priorities.

The research on urban forests in Chuncheon, so far, has mainly conducted in Ponguisan urban forest. Research on other urban forests in Chuncheon was scarce. Accordingly, in this study, the author chose the main urban forests in Chuncheon and tried to find a way of efficient establishment and management of urban forests in Chuncheon by field and questionnaire survey. The research findings, there were several reasons why effective management can not be implemented in the main urban forests in Chuncheon. To solve these problems and make an efficient establishment and management of urban forests in Chuncheon, the first way is to make forest management plans on the urban forest in Chuncheon and expand administrative organization, personnel and budget. Establishment and management of urban forests needs a practical, strengthened overall management system. The second way is to enhance the regional and functional characteristics for urban forest, expand the area of urban forests, and enhance management of Street trees. The third way is to designate Urban Nature Park or Urban Park for the main urban forests in Chuncheon and need to change the ownership of the urban forests by purchasing. The fourth way is to respond to Chuncheon citizen's preference and their way of utilization when create the urban forests in Chuncheon, expand convenience facilities, relaxation facilities as well.

Urban forests can help to improve the environmental quality of urban areas because trees mitigating of urban heat island and adapting cities to environmental changes.The increasing urban population has a direct impact on urban natural capital, which is urbanization have been replaced green spaces with impervious materials. Urban forests in Indonesia is very limited and not well-managed due to the urban forest was made without any form of consensus with the people, but an initiative of the city government. Some of facing problems that are high land costs, diversity of land ownership, social and environmental pressures, and the spread of financing sources and other resources in urban forest cultivation and maintenance. In Indonesia, financial resources to maintain and management of urban forest it is not problem if users recognize and understand that benefit and function of urban forest. Local government, company, owners building, NGO’s, local residents will participated in a partnership, but a key factor can influence of partnership is raise awareness and provide environment education; and legal aspect to supporting the partnership itself. This paper focuses on urban forests and financial resources in Indonesia. This paper concludes that urban forest management in Indonesia required a very large cost due to the high price of land, and they need participated of users and supporting legal aspect about who has responsibility of maintain and management of urban forest especially financial resources.
