    The both polycentric governance and Living Labs concepts are based on decentralized participatory planning, co-design, and decisionmaking. While the concept of Living Lab is still emerging, the Isar-Plan (2000 ~ 2011) pioneered the approach for selecting, co-designing, and implementing nature-based solutions along the Isar River in Munich, Germany. Despite multiple governing authorities involved in the decisionmaking process of the Isar-Plan, the polycentric governance that led to the success of the project has to date not been analyzed. This paper presents the results of an ex-post-analysis of the Isar-Plan restoration planning process based on stakeholder interviews and a literature review. The contribution describes the evolution of Isar-Plan governance arrangements and discusses the Living Lab approaches to cooperative governance. The analysis demonstrates how polycentricity facilitated trust, learning, and the co-design of a resilient waterscape. The paper concludes that Living Labs can be a way of applying polycentric governance when autonomous and multi-scale decision-makers are collaboratively involved in the design of policy solutions, and vice-versa.

    Streets are a focal point of human activities and a major interface of the social interaction between urban dwellers and urban built environment. A better understanding of the urban landscapes along streets is thus important in urban studies. The increasing availability of street-level images provides new opportunities for urban landscape studies to study and analyze streetscapes at a fine level and from a different perspective. In this study, we presented an application of a recently developed Deep Convolutional Neural Network on landscape analysis based on street-level images. Different urban features were identified from street-level images accurately using a trained Deep Convolutional Neural Network model. Based on the image segmentation results, we further measured the spatial distribution of the street greenery and quantitatively analyzed the openness of street canyons in Cambridge, Massachusetts. The proposed combination of Artificial Intelligence and the massively collected street-level images provides a new sight for urban landscape studies for cities around the world.

    Many urban areas affected by flood disasters are also becoming increasingly ecologically and socially fragmented due to the accumulation of vacant properties. While redevelopment is often viewed as the primary objective in regenerating vacant properties, they can also potentially provide ecological and hydrological land uses. Rather than chasing developmentbased incentives for regenerating vacant lots in high flood-risk communities, a balance should be sought between new developmental land uses and green infrastructure to help counteract stormwater runoff and flood effects, or “Resilience through Regeneration.” This paper uses landscape performance measures to evaluate the economic and hydrologic performance of green infrastructure regeneration projects for three marginalized neighborhoods in Houston, Texas, USA. Each project site is characterized by excessive vacant lots and flood issues. Results suggest that, when using green infrastructure to regenerate vacant properties, 1) flood risk continually decreases, 2) upfront economic costs increase in the short term (when compared to conventional development), and 3) the long-term economic return on investment is much higher.

    Wilderness is a cultural construct that is deeply rooted in many societies. For landscape architects and their predecessors, wilderness has long been important as a contrast to artificial garden elements, as an inspiration for naturalistic plant designs, or today as a timely contribution to reconciling cities and their inhabitants with the natural world. Since cities and wilderness have traditionally been seen as opposites, new approaches are necessary to better address the opportunities and challenges associated with wilderness in urban regions. From an ecological perspective, urban wilderness can be defined as an area characterized by a high degree of self-regulation in ecosystem processes where direct human impact is negligible. This allows two main types of wilderness to be distinguished: “ancient wilderness” represented by natural remnants in many cities, and “novel wilderness,” which arises in artificial urban-industrial sites. The two types require different approaches in designing and managing green spaces. Ancient wilderness is a traditional object of conservation and restoration, and offers inspiration for naturalistic plantings. In contrast, the emergence of novel wilderness has long been associated with neglect and socio-economic decline. Since the 1980s, however, early pioneer projects in Germany have started to integrate novel urban wilderness into the green infrastructure. The results are unprecedented green spaces that combine novel wilderness with design interventions. These places are attractive to visitors, contribute to biodiversity conservation, and support many ecosystem services. This article aims to illustrate the opportunities and challenges of integrating wilderness components and processes into the urban green infrastructure—a timely way to reconnect cities with nature.

    This paper discusses the possibility and direction of public participation and edible landscape construction in China's high-density metropolitan areas. It is based on the different types of community gardens completed by Shanghai Clover Nature School Teenager Nature Experience Service Center in recent years under the concept of "Urban Permaculture." By endowing rights to the inhabitants of the community, these examples have helped the participants become owners and established cooperation mechanisms between government, enterprises, social organizations, and the public.

    Urban greenways play a key role to a city’s nonautomobile commuting and help alleviate traffic congestion. Currently, China’s greenway planning research and practice focuses mostly on suburban areas where greenways provide ecological, historical, cultural, and recreational services, while fewer studies explore urban greenways that serve citizens’ daily non-automobile commuting and recreational needs. Compared with suburban ones, urban greenways often face more spatial limits in the built-up areas and need to respond to more challenging demands. Supported by multisource data and the rise of big data technologies, this research explores the methods of urban greenway route planning that are underpinned through GIS spatial analyses (potential evaluation on spatial construction conditions of greenways) and big-data-based user behavior analyses (of citizens’ daily use of greenways). Demonstrating the authentic planning case for Haidian District, Beijing, the research proposes a series of construction strategies to urban corridors of roads, waterways, and railways, respectively, which integrate green spaces with non-automobile system, in order to improve the services of linear spaces in cities.

    Tropical rainforest, a unique forest ecosystem with the richest biodiversity on the earth, is now suffering from rapid biodiversity loss and ecological degradation. Xishuangbanna is such a typical example in China, where the ecosystem of Sanda Mountain is fragmented by agricultural practices and rubber plantation, and the vegetation productivity decreases sharply, threatening its role in the regional ecological security pattern. For an overall ecological improvement of the study area, since 2017, the project team has examined the existing habitat conditions in Sanda Mountain and proposed a thirty-year planning scheme for the ecological restoration by introducing constructive and pioneer plant species, employing a mixedspecies planting mode, and facilitating the natural regeneration of vegetation community to recover natural succession through ecological restoration planning at patch-, corridor-, and regionalscales. The team simulated the changes in carbon storage, habitat quality, and ecosystem service value before and after planning via the InVEST model to guide the dynamic adjustment of the tropical rainforest restoration. This exploratory ecological restoration planning for such a largescale tropical rainforest may provide research and practical references for other studies in China and abroad.

    Natural wetlands play a vital role in maintaining regional water balance, regulating regional climate, and maintaining biodiversity. Due to urban sprawl in China, the loss of natural wetlands has been dramatic. In recent years, nature-based solutions, including wetland parks, have been advocated to compensate for this loss and to reduce vulnerability and disaster risks. As a result, inspired by natural wetlands or building on existing wetland ecosystems, hundreds of wetland parks have been created in China over the last decade. Most research on ecosystem services of wetland parks has to date focused on technical perspectives, with only a few addressing public perception; the public’s perception of wetland parks is not well understood. This research used social media (i.e. Sina Weibo) to access large volumes of data and provide temporal and geographic granularity. A semantic analysis of microblogs was performed to understand how the public perceives the ecosystem services of wetland parks in Guangzhou. This study explored the public’s perceptions and compared these with the ecosystem services as communicated by professional institutions, and probed into the factors that affect these perceptions. The results showed that the top three ecosystem services perceived by both the general public and communicated by institutions are recreation, aesthetics, and refugia / habitat. There is a strong interconnection between the perceptions of recreation and aesthetics services. Flowering plant species and colored-leaf trees are the most important stimuli affecting perceptions of aesthetics services, and birds are key to the perception of refugia / habitat services. These results provide a basis for better aligning management of projects utilizing naturebased solutions, such as wetland parks, with expectations from the public.

    Urban green space is attributed a significant role in addressing health challenges associated with urbanization. This is supported by evidence confirming that urban green space may both promote health and well-being and support nature-based treatments. Landscape architects who design to improving health outcomes have an important task; but one which also come with responsibilities. This is also noted by the World Health Organization, which states that it is vital to understand how to design green space so that it actually delivers the intended positive health outcomes. In order to deal with this situation, various tools and design guidelines have been developed by them. However, considered from a designer’s perspective, these tools are seldom expedient enough to apply in the design process, and the guidelines are often not as generalizable as supposed.

    In the current article, the authors present a process model for Evidence-Based Health Design in Landscape Architecture (EBHDL) and suggest that it may be useful as a means to deliver on stated health outcomes. The model has been developed over the last 15 years by the research group Nature, Health & Design at the University of Copenhagen. During this period, the model has been constantly enhanced via input evidence from researchers, practitioners, and university students. The EBHDL process model consists of four steps, all of which the landscape architect may be responsible for: Evidence collection, Programming, Designing, and Evaluation.

    The model has been applied in the design of the University of Copenhagen’s therapy garden, Nacadia®, and health-promoting forest, Octovia®. Based on encouraging results from research projects, the first step towards a validation of the EBHDL process model have now been made. The benefits of the model include the fact that it is interdisciplinary, systematic, transparent, and dynamic. A weakness of the model is that it is time-consuming, and thereby also costly.

    In the past decades, Space Syntax offers a series of theories and techniques to study the relationship between urban space and social-economic activities, and has been proved effective in analysis and design practices thanks to the open sources in the big data era. Taking the Chaoyang Square Renewal project in Jilin City, Jilin Province as an example, this article introduces the analyses of traffic volumes and visual integration of the square and the connected streets with modeling tools such as Segment Map and the intelligent multi-agent systems in Visibility Graph Analysis. All these analyses provided a basis for the full design process, from conceptual design to proposal evaluation, in order to activate this site through introducing pedestrian vitality. Prospects on new technologies in Artificial Intelligence, such as machine learning, are also explored to promote the research of Space Syntax and related application in urban design.

    Many articles have appeared in mainstream media and in techoriented venues about Sidewalk Labs’ ideas for a new hightech neighbourhood in Toronto (a project named Sidewalk Toronto). By and large, international commentary has focused on the opportunities and risks of giving over control over many city planning decisions to a private data-oriented corporation, with people lining up for or against “smart city” ideas, in general.

    This article will set aside generalities about “smart cities” and technology, and instead pose a few questions about the particulars of Sidewalk Toronto project. The first question concerns the striking lack of transparency of the agreement between Sidewalk Labs (a Google sister company) and Waterfront Toronto, the public authority promoting the project, which is not directly accountable to the city or the citizens. The second question concerns the equally striking ambiguity about which parcel of land is being sought by Sidewalk Labs — an ambiguity that suggests a worrying lack of concern, on the tech company’s part, about both local planning law and local real estate realities. The third set of concerns is about the ownership of the data that appears to be Sidewalk Labs’ real interest. Fourthly, problems in the contract award and procurement mechanisms will be raised. Finally, even though the agreement has not yet been seen even by city council, the process so far and the statements by both parties raise serious concerns about accountability, the fifth point raised in this article.

    As our cities and environments become more complex and face unprecedented challenges, it is no longer sufficient to design for aesthetics alone. Urban design, landscape architecture, and planning now demand going beyond typical design services to support deeper insights via foresight, research, experimentation, and innovative advocacy. SWA is one example of addressing these emerging complexities through two-year-old XL Lab, the firm’s platform for structured research and innovation projects. XL Lab differs and shares attributes with dedicated research teams in firms from allied fields such as architecture and engineering, where research entities that inform practice have been operating for longer than in landscape architecture. This article discusses the need for research in design now, what factors formed distinct research and innovation teams across the industry, their models and approaches, and how firms identify and prioritize research themes or issues taking XL Lab and another two research teams as examples.

    Most of the pressing challenges in the Anthropocene era are ecological, such as climate change and environmental degradation, all with profound impacts on socio-economics and equity. While ecology and resilience are among the most salient topics in contemporary landscape architecture, their inherent relationship and differences have deep implications on practice. The authors argue that ecology is all-encompassing and has a strong focus on system complexity without biasing or favoring any specific species or parts of the ecosystem. Resilience, when discussed in the context of planning and design, however, embodies a strong human-centric element. Ecocentric vs. anthropocentric perspectives provoke further discussion around an evolving relationship between ecological function and aesthetic forms that have been heavily informed by cultural and societal contexts.

    By translating environmental policies and social preferences, landscape architects command tremendous power to connect with the primary users of the built environment — the general public. Collaboration and integrated research are required to make significant progress on the complex environmental challenges the world faces today.

    The multi-functional landscapes for sustainable stormwater management play a significant role in providing various benefits on the environment, aesthetics, education, economy, etc. through the cultural ecosystem services, which have been underestimated by both the professionals and the public, due to the difficulty in their interpretation and quantification. The Importance-Satisfaction Analysis (ISA) makes it easier by evaluating the cultural ecosystem services with human’s perception, and was tested with the multi-functional landscapes for stormwater management in this research. The results show that aesthetic value, recreational / eco-tourism, and sense of place are the most valued cultural ecosystem services. Those cultural ecosystem services with a gap between their perceived importance and the public satisfaction with their delivery are also identified. ISA can discover the public’s perception and expectation of the stormwater management landscapes, which helps the decision-making about their improvement a lot.

    At the beginning, the author examines the concepts of natural environment, natural resource, and natural resource asset and the ecological services what natural resources could provide as ecosystems, including supporting services, provisioning services, regulating services, and cultural services. The author stresses that, in China, the survey and assessment of resource assets face many difficulties in defining ownerships and tenures, rights and responsibilities, and valuation, and extensive exploitation and utilization still dominates the country’s natural resource management. He argues that ecological damage and environmental degradation often resulted from overexploitation of resources; on the whole, China’s recent ecological restoration has not seen a substantial improvement, largely resulting from the separate and inconsistent practice, ill enforcement, and the weak public awareness of ecological remediation and restoration in the country. He highlights that China’s new reform of a Super-Ministry System (including the establishments of the Ministry of Natural Resources and the Ministry of Ecology and Environment), as well as the implementation of the Integrated Planning policy, has facilitated an integrated management on natural resource conservation. Finally, the author underscores that, in the future, the Chinese government ought to coordinate its land and spatial planning with domestic socio-economic planning, and urban planning professionals are expected to go beyond engineering and technical explorations and realize planning approaches as tools that would truly and efficiently cope with societal challenges and improve the quality of development.

    The Fourth Industrial Revolution is profoundly changing our cities with a series of disruptive technologies, characterized for the boom of Internet industries and the everyday application and wide integration of intelligent technologies. Individuals’ traditional mechanical thinking has changed into a mindset based on big data, whose cognition also relies more and more on a combination of both virtual and physical reality experience. At the same time, cities, where we live, are witnessing a significant revolution in resource utilization, societal conditions, and spatial use. Along with the surge of new technologies and new data represented by computer technologies and multi-source urban data, the (new) Urban Science, as a transdisciplinary combination of urban computing, Artificial Intelligence, augmented reality, and human-computer interaction, rises over the past decade.

    Urban green space structure and pattern have been one of the highlights in Landscape Architecture studies, accompanying with urgent demands of promoting ecological spatial structures in urban construction. Focusing on functional connectivity and construction strategies of the structure of green space network in Haidian District of Beijing, this research builds resistance surface and identifies linkages through habitat quality evaluation of the InVEST Model and the simulation with the Least-Cost Model, while adopting functional connectivity index (NL, NC, IIC, PC, and dIIL) to indicate the structural characteristics of green space network at varied distance thresholds. Results reveal that, on the whole, the distance threshold of 2,200 meters is most appropriate for the structure of the existing green space network of Haidian District, when 10 components and 353 linkages are identified and six important nodes and three important linkages that require a protection priority are further determined. Findings also disclose that the forest network of target tree species and that of water network of target water bird species are highly fragmented. Forest network serves in forms of dominant patch structure, local network structure, and fragmented cluster structure in the western mountainous area, the northern plain area, and the southeastern urban area, respectively. Moreover, the research proves that by introducing ten important linkages, the connectivity of forest network can be improved by 1.7 times, completing the overall structure in multiple directions and helping form a stable and resilient structure of the network. Finally, the research puts forward strategies for urban green space construction, including identifying construction objectives and target species, identifying and protecting important nodes and important linkages, and introducing possible important linkages and improving the structure of green space network, to help efficiently improve urban ecological quality.

    Half of humanity now lives in cities and the net inflow of population into cities will continue. Among all challenges faced by cities, the provisioning for water and sanitation is probably the most pressing one. From 2017 to 2018, the city of Cape Town in South Africa frequently made itself media headlines around the world, in many languages, for its severe water shortage due to consecutive years of drought that later resulted in a water crisis. Fortunately, the potential “Day Zero” when the city would run out of water, did not arrive. However, the crisis exposed a lack of resilience in the city’s water supply system in the face of ongoing climate change and a governance gap for climate adaptation. Many cities, especially those in the Global South, can learn from Cape Town’s experience and lessons on how to enhance governance to become more climate-resilient. Mark New and Gina Ziervogel, the interviewees, have been devoting themselves to studying about the Cape Town drought, and working on establishing the Cape Town Drought Response Learning Initiative. In this article, they analyzed the influence of climate change on Cape Town drought and the water supply system, and suggested effective methods to address and prevent the drought and water shortage. Ziervogel briefly described her adaptive and water-sensitive city framework while both of them revealed the role of Cape Town Drought Response Learning Initiative in making Cape Town more resilient.

    Nature-based solutions can help build resilience in urban landscapes. New governance arrangements have been suggested for assisting local governments in implementing nature-based solutions. A dominant nature-based solution initiative is the activities and policies directed at the increase of the number of trees and treecanopy coverage in a city. This study explores how polycentric governance of urban forests may operate by focusing on how key decision-makers coordinate their priorities and actions in urban forestry decisions. A stakeholder-centered view on polycentric governance is taken, specifically focused on the view of municipal managers, to develop a better understanding of the social systems behind the implementation of naturebased solutions. This was done by using social data elicited from 19 in-depth interviews with urban forest managers working in nine local councils in Greater Melbourne, Australia. The data analyses show that the most important decisions that municipal managers make, and where other stakeholders have the most influence, relate to tree removal for developments, significant tree retention, tree planting for site renewal, and ageing trees removal. The most important stakeholders influencing these decisions include other municipal departmental units, developers, state actors, and residents. Non-governmental greening groups do not play a very important role. Various types of coordination, such as the ones between municipal departments, between nongovernmental stakeholders (especially developers and residents), between state government policies, as well as public consultation, are needed to better mobilize stakeholders’ influence and input. Capitalizing on greening groups that aim to retain trees in urban areas, not just planting more trees, can potentially support the current decisions made by municipal managers, which respond to urbanization pressures.

    This article stresses the importance of positive image and perception of dynamic ecological processes for the implementation and care of areas which provide ecosystem services within the city. Those in turn secure the resilience of our urban environment. Aesthetic experience with emphasis on highlighting and revealing the presence of ecological dynamics, processes and cycles can increase the acceptance and interest for sustainable goals and projects within the city. Thus, several European cities are currently implementing strategies not only to enhance the capacity of their green networks for ecological services and resilience but most importantly to enhance the acceptance and active use of such areas. They are integrating the public in an open debate about implementing new attractive ecological amenities within a green network, and also stimulating landscape architects to find ways to design important ecological processes and functions in an eye-catching and spectacular way. The natural dynamics and cycles are thus brought to the attention of the people and present an important artistic and cultural component of resilience.

    In the past 30 years, Sanya has developed into a high-density city with fragmented ecosystems and bottlenecked urban development. In April 2015, the Ministry of Housing and Urban-Rural Development proposed “Ecological Restoration and Urban Remediation” for Sanya and prioritized the Sanya and Linchun Rivers — two rivers that run through the central city — as core causes. The Fengxinglong Ecological Park project is located at the junction of the two rivers in downtown and its surroudings are occupied for various land uses. Diversified urban interfaces, abundant green space, and numerous ecological contradictions make the site critical for the remediation and restoration of waterways in Sanya. Through a series of resilient landscape design interventions, Fengxinglong Ecological Park catches, stores, and purifies rainwater to reduce river pollution and flooding disasters in addition to offering recreational funtions. As a valuable “urban sponge” and comprehensive resilient ecological park, it has helped restore the historic ecosystem and realized the intensive use of resources.

    Uncertainty exists in the current urban development of contemporary cities and is getting diversified and complicated. Identifying and adapting to such uncertainty is partly defining the future development of urban planning and design. The concept of “resilient city” is developed from the current scientific demands in urban planning and design. This article suggests that Complex Adaptive System as a new system theory would help resilient city planning and construction. According to the Complex Adaptive System theory, a resilient city should possess the adaptability of its components, diversity, autonomy, appropriate redundancy, slow-variable management, and identification, in order to improve the ecological, social, and economic resilience and vitality of the city.

    This paper presents an integrated education and research program that involves extensive participation from stakeholders on campus and beyond. The resultant water conscious design proposal promotes efficient stormwater management on Utah State University’s campus, situated in the semi-arid Intermountain West. Utah State has adopted various “green” solutions for stormwater management, such as directing most campus runoff to recharge groundwater. Yet, there is no comprehensive plan that lays out its sustainable practices, and little quantitative assessment of the design performance has been performed. In accord with the University Campus Master Plan of 2011 and Campus Sustainability Plan 2013-2020, this paper addresses this gap and proposes a series of green infrastructure strategies that make use of rain as a resource, and that can be implemented across campus in three phases. A built green roof project is part of the Phase I master plan. Pilot performance data are presented regarding stormwater runoff and temperature reduction on a green roof surface versus an adjacent test-bed asphalt roof. In summary, the paper provides a holistic approach toward adopting green infrastructure designs and assessing green infrastructure performance in the less evaluated semi-arid climatic conditions, and it serves as an example of research through design process.

This article takes the wetland ecosystem construction in Furongba Bay, Hanfeng Lake as an example to explore approaches to designing multi-functional wetlands which could adapt to hydro-fluctuation and other environmental changes, by drawing from the ecological wisdoms of water regulation, conservancy, and utilization developed in the agrarian age of China to support a dynamic, multi-layered landscape of mutualism and co-evolution.

    The Dong’an Wetland was designated as the site for one of Sanya’s first pilot projects of urban environmental remediation and ecological restoration because of its key position in the regional ecological pattern, especially for urban stormwater management. The project aims at integrating leisure and recreational functions with landscape elements including ponds, forest on water, terraced vegetable garden, and trail loop, while promoting water circulation, improving water quality, and retaining rainwater and regulating water reuse, acting as a resilient urban sponge for rainwater management. The newly built project transforms an ignored grey place into a new home for egrets, an outdoor classroom for children’s nature education, and a destination for citizens to evoke their memories.

    Since the introduction of the 21st Century Maritime Silk Road initiative by President Xi Jinping in 2013, a series of relevant policies have profoundly influenced the development of coastal cities in China. The 21st Century Maritime Silk Road promises an open and inclusive new cooperation platform. It will help form a regional cooperation, which is driven by the key coastal cities and coastal economic zones. The 21st Century Maritime Silk Road brings new impetus to the development of coastal areas, leading to profound changes in regional agglomeration, industrial organization patterns, population migration, ecological protection, and other aspects.
