人文都市里的社会生态学

人文都市是概括和推进当代城市嵌合体中环境质量与社会质量的大标题。作为覆盖广泛、相互联系的社会生态体系,城市、郊区以及城市远郊的繁华地区凸显出不少负面特征。因此,人文都市发现了一个战略,可以对抗这些城市病并向城市系统逐步灌输更多积极的、可持续的特征。由于人文都市这个项目主要是在社会力量的推动下出现的,因此我们可以更清楚具体地表达科学在解决人文都市项目的问题以及评估其成就中的作用。人文都市可归纳为1）保护与保存城市与郊区的生态服务,2）提升居民的身体素质、心理健康与安全水平,3）保护能源、物质、水资源与时间以提高效率,4）以包容性促进公平以及社会和环境的公正性、合理性,5）保留社区感与场所感。我们将科学视为社会项目的促成因素,指出了推动科学的社会价值以及科学知识和科学隐喻在联系人文都市与社会项目中所扮演的角色。我们进一步指出社会生态研究在实现人文都市目标方面所扮演的角色,运用了环保历史、河涌的功能与复原、环境公平性、巴尔的摩生态系统和长期生态研究项目等行动案例。作为一个社会项目,人文都市得益于科学的投入：1）揭示城市体系中隐含的生态进程,2）创造知识,将普通人和一般机构与生物物理环境联系起来,3）为公民对话做出贡献,4）将科学价值观引入优化与平衡人文都市的目标当中。     

A comparative gradient approach as a tool for understanding and managing urban ecosystems

To meet the grand challenges of the urban century??such as climate change, biodiversity loss, and persistent poverty??urban and ecological theory must contribute to integrated frameworks that treat social and ecological dynamics as interdependent. A socio-ecological framework that encapsulates theory from the social and ecological sciences will improve understanding of metropolitan dynamics and generate science for improved, sustainable management of urban ecosystems. To date, most urban ecological research has focused on single cities. A comparative approach that uses gradients within and between cities is a useful tool for building urban ecological theory. We offer five hypotheses that are testable using a comparative, gradient approach: (i) the current size, configuration, and function of larger metropolitan ecosystems predicts the potential trajectory of smaller urban areas; (ii) timing of growth explains the greatest variance in urban ecosystem structure and function; (iii) form and function of urban ecosystems are converging over time; (iv) urban ecosystems become more segregated and fragmented as populations increase; and (v) larger cities are more innovative than smaller cities in managing urban ecosystems.     

Modelling of socio-ecological connectivity. The rural-urban network in the surroundings of Madrid (Central Spain)

As most of Europe’s metropolitan landscapes grow, a change is occurring in their surrounding rural environment. The consequences thereof mainly involve losses of traditional land uses and changes in the socioecomic structures of the local population. The lack of coupling ‘urban society-countryside’ can be considered to constitute a driving force of this process. The present paper focuses upon the rural-urban network around the metropolis of Madrid (Central Spain). We developed a quantitative model to explain the socio-ecological rural-urban linkages, taking into account the influence of the metropolis in the network of neighbouring municipalities. The results show a rural landscape gradient ranging from silvo-pastoral to agricultural land uses and maintaining different interactions with the local socioeconomy. Urban-rural polarisation of the territory and accessibility to the metropolis are the main factors influencing the landscape dynamics. Territorial cohesion among municipalities and connectivity with the metropolis are factors determining the socio-ecological structure. The agricultural area presents good social cohesion, but a weak connection with the City. The silvo-pastoral landscape, on the contrary, maintains prominent links with the metropolis, but a non-significant interconnection between the small towns. The model tested constitutes a useful tool for analysing socio-ecological connectivity and for quantifying, designing and promoting territorial cohesion policies.

Environmental stewardship footprint research: linking human agency and ecosystem health in the Puget Sound region

Urbanization processes challenge ecosystem health in many metropolitan areas. New policy and program approaches are needed to restore and sustain natural systems as public agencies and organizations face greater demands and declining budgets. Environmental stewardship is an often overlooked intervention strategy, and the full potential of civic engagement by citizens on behalf of ecosystem health is little understood. Using a coupled systems approach, integrated analysis of social and ecological footprints can lead to greater theoretical understanding and more effective programs at the landscape scale. Here we outline two pilot studies as part of an emergent research program that is investigating the extent and impact of environmental stewardship. Qualitative interviews of stewardship managers revealed multiple dimensions of motivations and purposes for stewardship, ranging from the practical to the conceptual. A regional organization census yielded a surprisingly large number of organizations that conduct stewardship, with social and ecological values being of comparable emphasis. The initial research is based in the Puget Sound area of Washington State, U.S., but results have relevance to other urban areas. Pilot study findings now guide additional research effort about motivations, organizational networks, and theory of integrated socio-ecological systems to be derived from comprehensive footprint analysis of stewardship activity.     

Asian urban sustainability in the era of globalization

The process of achieving urban sustainable development is uncharted. We only know that plans should address the economic, environmental and social health of the city and this task can only be accomplished by approaching each of these issues at different scales. For rapidly developing world cities, “sustainability” is becoming an increasingly elusive objective, in part, because of impacts by forces beyond their borders. Using the Asia-Pacific region as a case study, a framework relates regional transnational flows to the state of the urban environment and the social conditions of linked rapidly developing cities. The “functional city system” within the Asia-Pacific increasingly is both the engine of urban growth and the force behind differentiating urban environmental and social issues. At the same time, while globalization forces have been particularly strong within cities in the Asia-Pacific, local factors also play a crucial role in urban development. Globalization driven growth has not translated into a single path of development, rather localities have demonstrated contextually specific paths.     

The role of urban indicators in city management: a proposal for Croatian cities

Cities are dynamic economic and social structures that play a dominant role in both national and international economies. They are centers of population, production, consumption, and development. Cities utilize all advantages of economy of scale, proximity, and concentration. On the other hand, they produce high environmental pressures and diminish thereby the quality of life for urban residents. Indicators (environmental, economic, and governance and management) are seen as a tool that would help policy-makers in formulating urban policy that would lead cities towards sustainability and provide assistance for monitoring their development and municipal performance. The aim of this paper is to consider the role that urban indicators can play in city management. We present basic features of urban indicators that will determine their usefulness in urban management. This paper provides the framework to include environmental and economic indicators, as well as governance and management indicators, in successful urban management.

Social ecological complex adaptive systems: a framework for research on payments for ecosystem services

The environment is both a setting for and a product of human interactions. Understanding the dynamic nature of human-environment interactions is critical for mitigating the impacts of human induced environmental change and understanding how the environment shapes social systems. Current research has focused on the reduced ability of many natural systems to provide ecosystem services and the subsequent impact on human well-being. Furthermore, there has been a proliferation of cases analyzing the impacts of payment programs designed to enhance ecosystem services. However, analyses that link environmental policies through to their ecological results are not common and methods to do so are not thoroughly developed. To better analyze these interactions, a theory or framework is necessary. This article presents a framework of social ecological complex adaptive systems (SECAS). The framework links structuration theory from social science with the theories of complex adaptive systems from ecology to provide an enhanced understanding of the human drivers and responses to environmental change. The framework is presented as a recursive process where social and ecological systems are both the medium for and product of social action and ecological disturbance. A case study of Costa Rica’s ecosystem service payment program is presented as a demonstration of empirical applicability. This framework is proposed as a method to evaluate payments for ecosystem services, conservation policies, urban ecosystems, and for land use change in general.     

Urban ecosystems and sustainable urban development—analysing and assessing interacting systems in the Stockholm region

In order to build competence for sustainability analysis and assessment of urban systems, it is seen as essential to build on models representing urban form, landuse and transportation, urban metabolism, as well as ecological processes. This type of analysis of interacting sub-systems requires an advanced model integration platform, yet open for learning and for further development. Moreover, since the aim is to increase urban experience with ecosystem management in the wide sense, the platform needs to be open and easily available, with high visualisation capacity. For this purpose, the LEAM model was applied to the Stockholm Region and two potential future scenarios were developed, resulting from alternative policies. The scenarios differed widely and the dense urban development of Scenario Compact could be visualised, destroying much of the Greenstructure of Stockholm, while Scenario Urban Nature steered the development more to outer suburbs and some sprawl. For demonstration of the need for further development of biodiversity assessment models, a network model tied to a prioritised ecological profile was applied and altered by the scenarios. It could be shown that the Greenstructure did not support this profile very well. Thus, there is a need for dynamic models for negotiations, finding alternative solutions and interacting with other models. The LEAM Stockholm case study is planned to be further developed, to interact with more advanced transport and land use models, as well as analysing energy systems and urban water issues. This will enable integrated sustainability analysis and assessment of complex urban systems, for integration in the planning process in Stockholm as well as for comparative sustainability studies between different cities, with the goal to build more sustainable urban systems and to increase urban experiences in ecosystem management.     

Social-ecological innovation: adaptive responses to urban environmental conditions

Novel approaches to natural resource management, particularly those which promote stakeholder participation, have been put forward as fundamental ingredients for establishing resilient, polycentric forms of environmental governance. This is nowhere more pertinent than in the case of the complex adaptive systems associated with urban areas. Decentralisation of urban green space management has been posited as an element thereof which, according to resilience thinking, should contribute to the adaptive capacity of cities and the ecosystem services upon which they rely. Implicit in this move towards increased adaptive capacity is the ability to manage through innovation. Although the importance of innovation towards system adaptability has been acknowledged, little work has thus far been carried out which demonstrates that innovative use of urban green space represents a form of adaptive response to environmental conditions. The current paper reports on research which maps examples of organised social-ecological innovation (OSEI) in an urban study area and evaluates them as adaptive responses to local environmental conditions which may contribute to system resilience. The results present OSEI as a coherent body of responses to local social and environmental deprivation, exhibiting diversity and adaptability according to individual contexts. The study therefore provides evidence for the importance of local stakeholder-led innovation as in the building of adaptive capacity in urban social-ecological systems.     

Application of logic models in a large scientific research program

It is the purpose of this article to discuss the development and application of a logic model in the context of a large scientific research program within the Commonwealth Scientific and Industrial Research Organisation (CSIRO). CSIRO is Australia's national science agency and is a publicly funded part of Australia's innovation system. It conducts mission-driven scientific research focussed on delivering results with relevance and impact for Australia, where impact is defined and measured in economic, environmental and social terms at the national level. The Australian Government has recently signalled an increasing emphasis on performance assessment and evaluation, which in the CSIRO context implies an increasing emphasis on ensuring and demonstrating the impact of its research programs. CSIRO continues to develop and improve its approaches to impact planning and evaluation, including conducting a trial of a program logic approach in the CSIRO Preventative Health National Research Flagship. During the trial, improvements were observed in clarity of the research goals and path to impact, as well as in alignment of science and support function activities with national challenge goals. Further benefits were observed in terms of communication of the goals and expected impact of CSIRO's research programs both within CSIRO and externally. The key lesson learned was that significant value was achieved through the process itself, as well as the outcome. Recommendations based on the CSIRO trial may be of interest to managers of scientific research considering developing similar logic models for their research projects. The CSIRO experience has shown that there are significant benefits to be gained, especially if the project participants have a major role in the process of developing the logic model.     

BIMBY’s first steps: a pilot study on the contribution of residential front-yards in Phoenix and Maastricht to biodiversity,ecosystem services and urban sustainability

Large parts of urban space around the world exist of small-scale plots such as domestic gardens. These small-scale urban spaces carry potential for enhancing biodiversity, sustainability and ecosystem services in and beyond cities. However, domestic gardening and residential garden designs are often guided by aesthetics and ease more than by the aim to create habitat and biological diversity. Yard-management decisions impact socio-ecological systems in various ways, for example through irrigation patterns, fertilization or the use of pesticides or through the choice for exotic species that may become invasive over time. Yard-management decisions can also positively influence the presence of pollinators, improve soil quality or even foster small scale ‘Wildlife Habitats’ that can function as ecological stepping stones to the wider environment. In this paper a pilot assessment is presented of the contribution of residential front-yards in Phoenix (Arizona) and Maastricht (The Netherlands) to biodiversity, ecosystem services and sustainability by applying the BIMBY (Biodiversity in My (Back) Yard) framework.     

Socio-ecological systems and biodiversity conservation in African city: Insights from Kano Emir’s Palace gardens

Urban biodiversity management in most African countries is at a peripheral stage. At the same time, African urban areas substantially remain poorly planned and intensively growing. This study explores the socio-ecological system as an alternative approach to explore African indigenous urban biodiversity management. For this purpose, we mixed conventional scientific investigation methods to explain the biodiversity conservation in the ancient gardens of the Kano palace in northern Nigeria. This multidisciplinary approach has successfully unveiled a harmonious relationship of humans and ecosystems in the context of African cultural values and heritage systems. The paper reveals that the palace gardens offer an avenue for intersection of a wide range of ecological and cultural activities. These include biodiversity conservation, recreation, security and surveillance, climate hazards proofing, and sacred dimensions. The findings of this study show that it is possible to address challenges confronting Africa’s urban biodiversity through the combination of scientific and indigenous systems.

Subcommunity Change in a Changing Metropolis*

Residential areas in cities and suburbs change as they age. The conventional concepts that represent this process are succession and the neighborhood life cycle. In this study we use cohort analysis and multiple regression on small-area data from four censuses to examine population growth patterns among subcommunities in metropolitan Chicago,1940–70. The major findings: among city and suburban areas, cohort is a strong predictor of growth and loss. All suburbs grew early in the period studied, but older suburbs stabilized in the 1960s. Among city areas and suburbs, familism is a strong predictor of growth. Many areas in the city began to lose population in the 1950s, with accelerated loss in the following decade. City areas undergoing racial change in the 1950s lost population rapidly in the following decade. We conclude that the succession model, which is embedded in Burgess' city growth model, no longer accounts for change at the subcommunity level. Thus, the research confirms the life-cycle model but also points to the need for a new macro model of a nongrowing metropolis.     

Approaches to the study of urban ecosystems: The case of Central Arizona—Phoenix

CAP LTER focuses on an arid-land ecosystem profoundly influenced, even defined, by the presence and activities of humans and is one of only two LTER sites that specifically studies the ecology of an urban system. In this large-scale project, biological, physical, and social scientists are working together to study the structure and function of the urban ecosystem, to assess the effects of urban development on surrounding agricultural and desert lands, and to study the relationship and feedbacks between human decisions and ecological processes.Our interdisciplinary investigations into the relationship between land-use decisions and ecological consequences in the rapidly growing urban environment of Phoenix are of broad relevance for the study of social ecological systems and cites in particular. Refinements in our conceptual model of social ecological systems focuses our attention on recognizing the scales and periodicities of ecological and human phenomena, understanding the means and impacts of human control of variability in space and time, and finally an evaluation of the resilience of various aspects of socio-ecological systems especially their vulnerabilities and their potential for adaptive learning.

Copro-necrophagous beetles (Coleoptera: Scarabaeinae) in urban areas: A global review

The world has become an urban world, more than 50 % of the human population live in cities. The effects of urbanization are diverse, complex and wide; ranging from unbalanced biogeochemical cycles in urban areas, to the local extinction of several species in different cities around the globe. However, diverse biological groups live and thrive in cities adapting to the new and sometimes harsh conditions of urban areas. In an effort to compile and assess the current status of knowledge of copro-necrophagous beetles in urban areas, we performed an extensive search for publications regarding Scarabaeinae beetles in urban areas. We found 27 publication that address four general topics: (1) ecological patterns; (2) disease transmission; (3) conservation biology; and (4) species lists. Although in the last fifteen years it has been published extensively about Scarabaeinae as an indicator group in biodiversity studies and in the analysis of ecosystem functions, references to Scarabaeinae in cities are scarce. In a broad sense, the study of copro-necrophagous beetles in urban areas is in an early stage of advance, providing an opportunity for entomologists to explore their response to urbanization, altogether with the role of these insects as host and intermediates of parasitic diseases, but also, with the environmental services provided by them, like the burial and destruction of a great amount of excrements found in urban soil.     

Notes on the evolution and organization of the urban ecosystem

The continual spread of human settlements over the world’s surface has transformed the natural environment on a global scale. Human’s intervention has changed primary ecosystems (protoecosystems or euecosystems) into anthropoecosystems. The spread of urban ecosystems, cultivated surfaces (agroecosystems), and various areas differentiated by their level of anthropization has facilitated the progressive reduction of euecosystems. The evolution of urban areas over the course of history with transformations of cities and surrounding territory, has created very complex mosaics. A proper study of the city, drawing together historical, cultural, social, and other factors, as well as abiotic ones (urban climate, soil, water, air), requires appropriate, uniform terminology for expressing the complex relationships existing among these factors. We therefore propose that the city (or metropolis) be considered as a set of ecosystems, a “synecosystem”. The entire urban area should be termed a “synbiotope”. It is divided into numerous partial biotopes (macro-, meso- and microbiotopes), the result of modifications wrought through the historical and cultural vicissitudes of the human population. Urban biotopes host not only humans, but also a characteristic vegetable and animal component, the “biosyncoenosis”, formed of numerous plant and animal communities, selected on the basis of the environmental conditions of the individual biotopes, which differ from each other in structure, dynamics, age, and position in the urban space. This terminology should facilitate study of the biotic component and its connection to the urban territory, as well as interpretation of results obtained in the different disciplines in terms of the human population’s quality of life.
