The valuation of ecosystem services has become an integral part of smart urban planning practices. Traditionally designed to bridge ecology and economy through economic language and logic (e.g., goods and services), this conceptual framework has developed into an effective tool for interdisciplinary work. The concept of ecosystem services is used to improve the management of ecosystems for human well-being. However, gaps in how to govern ecological benefits remain. Specifically, identifying which stakeholders benefit the most from the provision of ecosystem services remains largely unaddressed. This study examines the spatial discordance between ecosystem services and the residential stakeholders who may benefit. Using a landscape approach to quantify urban ecosystem services, an area-based composite index was developed for the City of Toronto, Canada, based on the three pillars of sustainability in order to identify potentially vulnerable populations. This method combines the use of principal component analysis (PCA) and spatial multicriteria decision analysis (GIS-MCDA) to combine and weight a select grouping of socioeconomic and ecological indicators. In addition, two sets of enumeration units (i.e., dissemination areas and census tracts) were evaluated to assess the potential impact of measurement scale on subsequent decision or policy outcomes. Results indicate the spatial interdependencies between ecological and socioeconomic processes in an urban setting, offering a unique framework for novel planning and policy intervention strategies. The influence of measurement scale was demonstrated, creating an opportunity to assess an appropriate policy scale by which to measure and evaluate trends over time and space. This approach seeks to provide a flexible and intuitive planning tool that can help to achieve goals relating to urban sustainability, resiliency and equity.

Land degradation usually leads to the loss of ecosystem services, which may threaten social well-being. There is no approach to identify and manage all ecosystem services based on their importance in degradation processes and social systems. This study aimed to link ecosystem services to social well-being in order to assess rangeland degradation. Eleven ecosystem services (forage production, water yield, edible plants, fuel, medicinal plants, pollination, gas regulation, soil resistivity to erosion, soil fertility, scenic beauty, and recreation) were assessed in a semiarid rangeland near Bardsir city, Kerman Province, southeast Iran. There were significant differences between the rangeland types in providing ecosystem services (p < 0.05). Four criteria and 17 indices of social well-being were weighed according to their importance for local stakeholders. Rangeland degradation was estimated using the weight of the indices for social well-being and ecosystem services. Discriminant analysis indicated that supporting services (soil fertility) and provisioning services (water yield and forage production) had the greatest impact on rangeland degradation, which is related to food security in social well-being. Ecosystem services and social well-being declined in medium and severe degradation due to plant composition change and overgrazing based on principal component analysis (PCA). More than 70% of the watershed has been highly and severely degraded. There was a trade-off relationship between ecosystem services and social well-being in very severe degraded areas because of social well-being promotion due to agriculture expansion. Based on our approach, the loss rate of the ecosystem services and social well-being indices in each degradation category is a good guide for management programs and decision-makers to meet both the needs of the people and the preservation of ecosystems.

Cities have a wide variety of green infrastructure types, such as parks and gardens. These structures can provide important ecosystem services (ES) with a major impact on human well-being. With respect to urban planning, special consideration must be given to such green infrastructure types when implementing measures to maintain and enhance the quality of life. Therefore, generating knowledge on the urban ES of differently scaled green infrastructure types is important. This systematic literature review provides an overview of existing studies which have explicitly investigated the urban ES of differently spatial-scaled green infrastructure types. By reviewing 76 publications, we confirm rising academic interest in this topic. The most frequently assessed urban ES belong to the category Regulating and Maintenance. Only a few have considered individual small structures such as green roofs or single gardens; green spaces are often aggregated into one, mostly city-wide, object of investigation, with resulting oversimplifications. Moreover, generalizing methods are mostly applied. Simultaneously, many studies have applied methods to evaluate location-specific primary data. More research is needed on small-scale structures, in particular to consider site-, and thus location-specific, parameters in order to successfully implement the ES concept into urban planning and to obtain realistic results for ES assessments.

<p><em>Idea and Objectives:</em> This case study presents first findings of the GreenCityLabHue project. The project aims at implementing an urban learning lab in the city of Hue, Vietnam, for the participatory identification and implementation of innovative nature-based solutions for the protection and improvement of urban ecosystem services and climate change adaptation. We will present urgent environmental and societal challenges for the city of Hue, including the estimated impacts of climate change and resulting disaster risks. Subsequently, we will discuss elements of the green-blue infrastructure to tackle these risks in a sustainable and environmentally just manner in the context of a proposed typology of nature-based solutions. This typology specifically shifts the focus from a European perspective towards nature-based solutions that are locally relevant to strengthen the resilience of Hue and comparable cities in Central Vietnam and/or South-East Asia.</p><p><em>Background:</em> Vietnam is a country that faces multiple challenges. It is a country that experiences rapid urban growth, with an estimated 50% of citizens living in urban areas by 2030 up from 35%, resulting in urban expansion that necessitates safeguarding urban ecosystem services, e.g., for the protection of human health and human well-being. Vietnam is also heavily affected by climate change. Particularly in Central Vietnam, cities face increasing risks of flooding, storms, and temperature extremes.</p><p>By providing multifunctional ecosystem services and diverse benefits, nature-based solutions—and in particular green-blue infrastructure elements—may help to address the aforementioned environmental and societal challenges in a sustainable and integrative manner, e.g., for maintaining air quality, stormwater mitigation, climate regulation, and improving environmental equity.</p><p>Hue is the capital of the Thua Thien-Hue province, located in Central Vietnam on the banks of the Perfume River. It has a population of approximately half a million people, represents a touristic and educational hotspot, and is rated a “top priority city” by the Vietnamese government. In Hue, first steps that consider strengthening the green-blue infrastructure were devised in form of the Hue GrEEEn City Action Plan. However, a more holistic urban planning approach that also addresses challenges related to climate change is still lacking.</p>

Among the many types of terrestrial ecosystems, forests have some of the highest levels of biodiversity; they also have many interdependent economic, ecological and social functions and provide ecosystem services. They supply a range of tangible, marketable goods, as well as a variety of nonmarketable and intangible services derived from various forest functions. These translate into social, cultural, health and scientific benefits for people’s quality of life. However, because they cannot be traded on a market, nonmarketable and intangible services are often perceived as free, inexhaustible and, as a result, underestimated. The human–nature interaction has affected both nature (via resource consumption) and society (via development of human welfare and well-being). Decision-makers, both public and private, often manage natural capital for multiple aims. In recent years it has been found that the single, individual approach estimating the value for these goods and services is not able to provide information that generates and supports decisions and policies in complex areas of current relevance such as the constant loss of biodiversity, climate change and global warming in close connection with the need for social development and ensuring an acceptable level of well-being for the greatest part of humanity. An integrated assessment with advanced techniques and methods using a pluralist framework of a heterogeneous set of values is considered a better approach to the valuation of such complex nature of the ecosystem goods and services. This assessment should take into account both costs and benefits trade-off issues among the multiple uses of ecosystem goods and/or services, especially the relationships between them and how they influence or determine the economic, social and cultural development of society. It should also consider the estimation of the complex inverse effect, from society to nature, whose goods and services can be diminished to exhaustion by the extensive and intensive anthropization of natural ecosystems with major impact on the number and quality of goods and services provided by ecosystems. Research has shown that applying an integrative assessment approach that utilizes tools developed by sustainability sciences could be an important component of future environmental policy making.

Nyando wetland provides several ecosystem goods and services, i.e., provisioning, cultural, supporting and regulating which are essential for human well-being for making life possible and worth living. Payment for Ecosystem Services presents one key question in current literature on whether local communities are aware of ecosystem services provided by wetlands. This paper contributes to the understanding of the local community’s level of awareness of the ecosystem services provided by Nyando wetland in Kenya as a strategy to improve protection of wetlands. The study is significant as it proposes policy options that can assist conservation authorities and local communities in management of wetlands. A stratified random sampling based on two administrative sub-counties, namely Nyando and Nyakach was employed to collect quantitative data from 394 households using a structured questionnaire. The quantitative data was subjected to descriptive statistics and Chi-square test which were performed in SPSS version 20. The results confirmed that the local community is more conversant with the provisioning ecosystem services (37.7%) compared to the other classes of ecosystem services. Despite the locals being involved in community based natural resource conservation initiatives, majority of the respondents (69%) were not familiar with the concept of Payment for Ecosystem Services. Therefore, there is need to create awareness and capacity building to local communities on the importance of both the wetland ecosystem services and Payment for Ecosystem Services in conservation of wetlands for enhanced community livelihoods. Keywords: Payment for ecosystem services; wetland; conservation; community; livelihood; awareness

Green infrastructure (GI) planning is becoming a pre-eminent approach for delivering essential goods and services to people while reversing trends such as landscape and habitat fragmentation. By means of sound ecosystems delivering multiple services and benefits, GI can contribute to public health, including physical, psychological, and social aspects. These services and benefits are provided at the local, regional, and national scales, and are therefore closely knit to planning and policymaking at various levels. The Green Infrastructure Framework was conceptualized to incorporate the multifunctional, multiscale, and temporal dimensions of GI and to demonstrate the associations between ecosystem services and human well-being. It stresses biodiversity, social and territorial cohesion, and sustainable development as key contributions of GI, creating the environmental settings for well-being and community health. Adopting the GI approach and its characteristics of connectivity (by connecting ecological and social systems), accessibility, and functionality in urban planning may contribute to healthier societies.

The complexity of urban spatial configuration, which affects human-well being and landscape functioning, needs acquisition and 3d visualisation data to inform decision-making process better. One of the main challenges in sustainability research is to conceive spatial models which are capable of adapting to changes in scale and recalibrating the related indicators depending on the degree of detail and data availability. In this perspective, the inclusion of the third dimension into Urban Ecosystem Services (UES) assessment studies highlights the details of urban structure-function relationships, improves modelling and visualisation of data and impacts, aiding decision-makers to localise, assess and manage urban development strategies. The main goal of the proposed framework concerns mapping, evaluating and planning of the UES within a 3d-virtual environment to improve the visualisation of the spatial relationships among the services allocation and the urban fabric density.

Rocinha (Rio de Janeiro, Brazil) is the largest favela in South America. It is located on a steep mountain slope in the Tijuca National Park with a population of over 160,000 living in poor environmental, health and hygiene conditions. The geomorphological and urban setting of Rocinha makes it vulnerable to natural hazards, with the greatest risk posed by flooding or landslides, compromising the precarious balance between ecosystem services (ES) provision and human well-being. The paper aims to assess and map ES provision in a context where available data to identify areas vulnerable to natural risks is limited. The ES analyses were adapted to the specific socio-economic and environmental context of favelas, which are characterised by dense, continuously built-up environment and a high proportion of impervious surfaces, leading to deteriorating environmental, health and hygiene conditions over time. The ES-based approach was pivotal for setting out strategies—including nature-based solutions (NBS)—to mitigate disaster risk and increase local resilience. These strategies were selected taking into account the context of Rocinha and feasibility. The research shows that ES assessment can be the starting point for projects based on NBS with a view to increasing resilience even in environmentally critical contexts.
