John Perry is known for his work on personal identity, and Jon Barwise, Director of the Center for the Study of Language and Information at Stanford, is a logician who works on model theory. Their cryptically titled collaboration is a first book-length foray into the semantics of natural language. Situations and Attitudes is programmatic even where detailed, and a sequel is promised which will carry through the program extensively and with full-dress technical detail. The program, for which the basic theoretical (...) machinery, the central categories, and the broad rationale are provided in this book, is an "innocent" model-theoretic semantics of natural language, in the spirit of realism and with debts to the likes of Putnam, Kripke, Donnellan, Montague, and psychologist J. J. Gibson. The authors describe their realism as "ecological" because they view meaning as a ubiquitous phenomenon of sentient organisms' natural and necessary attunement to constraints on the flow of information throughout their surrounds. They see an adequate semantic theory accounting for how language fits into the general flow of information. Their view is a realism not only in stressing the external significance of language, the primacy of its function of conveying information about the external world, but in seeing meaning itself as an objective uniformity in that world, a systematic relation of a special sort between different types of situations. The "innocence" of this semantics emerges in its leading concern--a correct treatment of the famously troublesome verbs of attitude which are used to embed sentences and so to report perception and cognition. Barwise and Perry refuse to sacrifice the view that sentences embedded in attitude reports "work just as they do elsewhere," i.e., are about situations, parts of the real world. The broader innocence is that of non-collaboration in the "Fregean tradition" of philosophical semantics which is "seriously flawed" by its inappropriate emphases, due to preoccupation with mathematics and symbolic logic, on univocal expressions, eternal sentences, entailments between sentences, arbitrariness and uniqueness of the name-named mapping, and a general tendency to think that all information available from an utterance must be part of its interpretation. The book counters that tradition on these points and others. (shrink)

There are many ways to describe cities. As a physical environment, more so than many other environments, they are at least an extension of our present intentions. But cities are not confined to the moment. Built spaces are also in conversation with the past and oriented toward the future as physical manifestations of our values and priorities. But even with all of the ways we have to describe cities we do not normally think of them as in any way akin (...) to the “natural” environment. City and country, nature and culture, are opposed. We move through cities differently, with a different set of values, whether articulated or not. Consider just one small example: Even the most jaded urban dweller may hesitate to sully the environment around him when he perceives it to be something other than a product of the human community. Though we have all seen trash in a national park, we suspect (or at least hope) that there is a kind of hesitancy that occurs with a person wondering what to do with her candy wrappers on a trail in Yosemite. On the other hand, a visitor to my home, Greenwich Village, will usually not think twice about tossing his cigarette butts on the ground as he walks toward his next destination. (shrink)

Laguna Lake, the largest lake in the Philippines, supplies Manila's dense urban region with fish and water while operating as a sink for its stormflows and wastes. Transforming the lake to deliver these multiple urban ecological functions, however, has generated resource conflicts and contradictions that unfold unevenly across space. In Urban Ecologies on the Edge, Kristian Karlo Saguin tracks the politics of resource flows and unpacks the narratives of Laguna Lake as Manila's resource frontier. Provisioning the city (...) and keeping it safe from floods are both frontier-making processes that bring together contested socioecological imaginaries, practices, and relations. Combining fieldwork and historical accounts, Saguin demonstrates how people--powerful and marginalized--interact with the state and the environment to produce the unequal landscapes of urbanization at and beyond the city's edge.

Environmental aesthetics has become a matter of concern to many different groups in recent years—to conservationists, to legislators, reluctantly to industrialists, and indeed to the public at large. This interest seems to have a clear purpose. It is regarded as an effort, belated and desperate, to save the resources and beauties of our natural world from the possibility of complete and irrecoverable exploitation, and from the disfigurement and loss that must follow. It is an attempt to change the atmosphere from (...) a toxic medium that is often impossible to escape back to one that is fresh and invigorating. It is a proposal to rebuild our cities before they become unredeemable wastelands of physical and social decay. (shrink)

Connolly draws on the recent changes in the Malaysian state of Penang to open up new perspectives on urban development, governance and the politics of place. Reviewing the role of residents, activists, planners and other experts in socio-natural changes and urban regeneration, it builds an important new framework of landscape political ecology.

The article presents the results of an interdisciplinary (psychological, behavioral, sociological, urban) survey of residents of elite residential complexes of Odessa regarding theirs urban infrastructure preferences, as well as the degree of satisfaction with their place of residence. It was found that respondents are characterized by a high level of satisfaction with their place of residence. It was also revealed that the security criterion of the district is the main one for choosing a place of residence, which indicates (...) the unmet townspeople need for the general safety of the urban environment. Based on the obtained empirical data, an analysis of significant factors affecting the urban infrastructure preferences of residents from the point of view of the systemic concept of the social ecology of the city is conducted. Obtained data viewed that living in high-rise (multi-storey) buildings correlates with a low level of satisfaction, while low-rise buildings positively correlate with such significant aspects as the view from the window, a small number of neighbors, proximity to the sea, and effective house management. Multivariate regression revealed a positive relationship with such infrastructure objects as shopping and entertainment centers, postal services, places of family leisure, etc., which indicates the dominance of the consumer strategy in the behavior of the city resident. The collected empirical material served as the base for identifying the behavioral trends of the townspeople and allowed to simulate a qualitative profile of the activity of everyday support and personal development.

Interdisciplinarity has been a key term in the ecological debate ever since its advent in the early 1960s. The paper addresses these historical links and how the two terms ‘interdisciplinary’ and ‘ecology’ have influenced each other. The later concept ‘sustainable development’ is also truly interdisciplinary, including physical, biological, socio-economic and cultural, as well as normative, mechanisms, contexts and effects operating at scales ranging from the microscopic to the macroscopic. Policies to promote sustainable development need to be based on the (...) type of interdisciplinary thinking that has been advocated for several decades within the ecological debate. This applies not least to research into the sustainability aspects of urban development, the case discussed in this paper. Despite longstanding requests for interdisciplinarity, the development within the academic world has proceeded in the opposite direction. Many of the most influential metatheoretical perspectives virtually prohibit, or at best strongly discourage, the inclusion of insights about certain parts of reality. Here, critical realism could play a very important role as an underlabourer of interdisciplinarity. (shrink)

This book analyzes how science-based nature protection campaigns are transforming society and the environment through extensive fieldwork in China's southwestern cities. Furthermore, it examines the role of ecology in constituting state power and social inequality.

With a few notable exceptions, urban garden scholarship tends to be either celebratory or critical of the role urban gardens play in wider political, social, cultural, economic and ecological dynamics. Drawing on urban political ecology scholarship, this article explores the question of nature within scholarship on urban gardens. I argue that failing to adequately scrutinize the co-constitutive character of nature and society has led some scholars to overlook the potential for urban gardens to achieve (...) broader socio-political goals, and led others to overstate the potential. Employing a political ecology approach to urban garden analysis clarifies the material and discursive role of nature in urban garden practice, and ultimately contributes to untangling the potential and limits of urban gardens as sites of socio-political change.

This article demonstrates how white Christianity in urban South Africa is fated by demographic change. The repeal of apartheid in 1994 enacted some sociocultural changes in urban South Africa. The white population exited the city and town centres, followed by the black South Africans. The historical relationship of the government under the National Party (NP) and the Dutch Reformed Church (DRC) led to latters’ redundancy in the cities. The cultural development towards multiculturalism led to polycentric focus where the (...) suburban peripheries and the city centres experience some form of socio- and cultural-economic developments. Two proposals are made to redress the situation. Firstly, a rethinking was suggested of the theology of the city, which should always demonstrate solidarity with the poor and the marginalised trapped within the decadent city culture. Secondly, a missiological refocus was suggested, which should pursue, embrace and include activities that are not paternalistic. (shrink)

To establish the evaluation index system of urbanization innovation level and ecological efficiency, the entropy method is applied to measure the comprehensive index of urbanization innovation level and ecological efficiency, the VAR model is established, and empirical measurement is used to study the internal relationship and dynamic development between urbanization innovation level and ecological efficiency. The empirical results show the following: The overall development of the innovation level in 30 cities in China is uneven, there is a large gap between (...) the urban innovation level in backwards areas and economically developed areas, and there is a certain coupling effect between the urban innovation level and ecological efficiency. There is a long-term dynamic equilibrium relationship between the urban innovation level and ecological efficiency, which will exert certain pressure on the ecological environment in the process of urbanization. However, the continuous improvement of urbanization will have a positive impact on the improvement of the ecological environment. The improvement of ecological efficiency will also promote the improvement of the urban innovation level. Therefore, this paper puts forwards policy suggestions to promote the harmonious development of urbanization and the ecological environment and provides a reference for realizing the balanced development of urbanization and ecological efficiency in China.

Thirty years after the death of Michel Foucault, notwithstanding the fact that his thought has profoundly shaped the contemporary reflection and contributed to move beyond structuralism, the Urban Political Ecology in general and the Urban Political Ecology of water in particular are still dominated by Marxist-inspired theoretical frameworks. This paper aims to provide a theoretical rationale for the development and implementation of a Foucauldian ap-proach to the UPE of water. We show how a Foucauldian approach could (...) shed light on the hydro-social cycle and could be the basis of a specific form of scholarly political engagement. (shrink)

Considering that the development of urbanization cannot be separated from the application of landscape pattern evolution, in order to improve the development level of ecocity, a modeling analysis of ecological urban landscape pattern evolution based on multisource remote sensing data is proposed. Taking ecotype city as the research object, the remote sensing images of ecological urban landscape pattern are screened by using multisource remote sensing data and nonremote sensing data as the basic data. CA-Markov model is constructed and (...) the evolution of ecological urban landscape pattern is analyzed. The experimental results show that, from 2005 to 2020, the development level of urbanization process is higher and higher and the area of building land patches is increasing, which reduces the fragmentation of building land patches. However, the landscape of cultivated land and green space is less and less, and the distribution of the patches also causes uneven phenomenon, which leads to the gradual decline of ecological urban landscape diversity. In the ecological urban landscape pattern, the degree of fragmentation and diversity of urban landscape is reduced due to the high connection and coverage of the construction land. (shrink)

The basic motivation for this article is to explore the critical, yet hopeful vision which urban theologians - and specifically ecofeminist urban theologians - have for justice, reconciliation and abundance of life in urban Gauteng. This requires that urban spatiality, with its conflicting sides in a rampantly capitalist Gauteng, needs to be understood. It also requires an understanding of how urbanity and ecology may - yet so often do not - overlap. According to ecofeminist theologian (...) Anne Primavesi, space and place needs to be understood in relation to the earth as the body of God - a web of interrelated and interconnected subjects and living beings which constitute the earth with its various ecosystems. This belies the established understanding that space and place is created mostly through the anthropocentric activity and mastery of people. Such an ecological understanding of space, place and urbanity leads to my exploration of a missiology of space as the manifestation of the presence of God in the spaces of nature and human civilisation. I conclude by proposing the practice of urban mission as making the liturgical and sacramental links between ecology, space, and the reclamation of urban space as sacred by Christian and other agents of urban activism.

ABSTRACT Departing from the hegemonic position of epidemiology in population physical activity research and policy, I argue for the significance of a complementary, holistic approach: human movement ecology. The argument is developed in two steps. In a first step, and using perspectives from body ecology and eco-philosophy, I emphasize the potential in movement of a ’dynamic and spontaneous ecologization’, which opens for the development of ecological consciousness and sustainable practice. In a second step, I test HME towards a (...) ’hard case’: everyday routine walking in urban settings. Even here, and paying particular attention to the nature of habitual movement and the need for a ’greening’ of urban environments, I point to a significant movement ecological potential. I conclude that HME provides a fertile and complementary conceptual alternative to PA epidemiology. The challenge of low population PA levels is probably best met with facilitating for movement as an integral part of a sustainable everyday life. Actually, with an increased realization of HME ideals in practice, instrumental PA policies would become less relevant and, on a longer-term basis, perhaps not needed at all. (shrink)

Urban residents have the potential to play a key role in helping to facilitate ecological resilience of wilderness areas and ecosystems beyond the city by helping ensure the migration of nonhuman climate refugee populations. Three ethical frameworks related to this issue could determine whether we have an ethical duty to help nonhuman climate refugee populations: ethical individualism, ethical holism, and species ethics. Using each of these frameworks could support the stronger view that policy makers and members of the public (...) have a moral duty to mitigate the impacts of climate induced migration, or the weaker claim that these impacts should be taken into account when making land-use and planning decisions in urban contexts.

Urban agriculture in Cuba is often promoted as an example of how agroecological farming can overcome the need for oil-derived inputs in food production. This article examines the geographical implications of Cuba’s low-carbon urban farming based on fieldwork in five organopónicos in Pinar del Río. The article charts how energy flows, biophysical relations, and socially mediated ecological processes are spatially organised to enable large-scale urban agricultural production. To explain this production system, the literature on Cuban agroecology postulates (...) a model of two distinct modes: agroecology versus industrial agriculture. Yet this distinction inadequately explains Cuba’s urban agriculture: production in the organopónicos rather sits across categories, at once involving agroecological, organic-industrial, and petro-industrial features. To resolve this contradiction, a more nuanced framework is developed that conceptualises production systems by means of their geographical configuration. This provides analytical clarity—and a political strategy for a low-carbon, degrowth agenda. (shrink)

Urban animals can benefit from living in cities, but this also makes them vulnerable as they increasingly depend on the advantages of urban life. This article has two aims. First, I provide a detailed analysis of the concept of captivity and explain why it matters to nonhuman animals—because and insofar as many of them have a (non-substitutable) interest in freedom. Second, I defend a surprising implication of the account—pushing the boundaries of the concept while the boundaries of cities (...) and human activities expand. I argue for the existence of the neglected problem of pervasive captivity, of which urban wildlife is an illustration. Many urban animals are confined, controlled and dependent, therefore often captive of expanding urban areas. While I argue that captivity per se is value-neutral, I draw the ethical and policy implications of harmful pervasive captivity. (shrink)

In the United States, interest in urban agriculture has grown dramatically. While community gardens have sprouted across the landscape, home food gardens—arguably an ever-present, more durable form of urban agriculture—have been overlooked, understudied, and unsupported by government agencies, non-governmental organizations, and academics. In part a response to the invisibility of home gardens, this paper is a manifesto for their study in the Global North. It seeks to develop a multi-scalar and multidisciplinary research framework that acknowledges the garden’s social (...) and ecological or material dimensions. Given the lack of existing research, we draw on the more extensive literature on home gardens in the South and community gardens in the North to develop a set of hypotheses about the social-ecological effects of urban home food gardens in the North. These gardens, we hypothesize, contribute to food security, community development, cultural reproduction, and resilience at multiple scales; conserve agrobiodiversity; and support urban biodiversity. They may also have negative ecological effects, such as stormwater nutrient loading. Because of the entanglement of the social and the ecological or material in the garden, we review three theoretical perspectives—social ecological systems theory, actor-network theory, and assemblage theory—that have been or could be applied to the multi-scalar and multidisciplinary study of the garden. We also review sampling and analytic methods for conducting home garden research. The paper concludes with a discussion of opportunities to extend the research agenda beyond descriptive analysis, the primary focus of garden research to date. (shrink)

Rosario, Argentina, a city of more than one million people strategically located on the Paraná River in the heart of a fertile agricultural region, is home to a significant industrial corridor where ongoing urbanization for industry, including that associated with the port complex and agroexport industries, vies for real estate space with peri-urban and urban farming production. The city is also the site of thriving municipal programs seeking to change food production and consumption outcomes through urban and (...) peri-urban agriculture projects rooted in agroecology. This paper identifies the socio-natures critical for the formation and endurance of these agroecology assemblages. Based on interviews with 30 stakeholders in government, civil society, and agricultural production, we describe the integrated approach to environmental, social, and economic sustainability embedded in Rosario’s institutional agroecology programs. In particular, we discuss the actors and strategies, discursive renderings of socio-natures, and the marketing of agroecological materialities that form and are formed by these assemblages. We also discuss the power dynamics embedded in sustaining urban and peri-urban agroecological projects through institutional means. This research contributes to literature on agroecology, urban agriculture, and the urban metabolism through providing empirical examples of socio-natural entanglements in urban agroecological assemblages.

Parental investment decisions guide parental actions regarding children’s productive work and are shaped by ecological context. Urban ecology enhances long-term payoffs to investment in human capital, increasing opportunity costs for work performed by children, and decreased workload should result.

Results show higher workloads for older children, rural children, and girls. High scholastic achievement is associated with lower workloads for girls, but (...) not boys. This pattern is interpreted as daughter-biased investment in the context of urbanization. (shrink)

In “Farming Made Her Stupid,” Lisa Heldke suggests that those who inhabit the metrocentric position participate in the marginalization of rural people and farmers through a process of “stupidification.” Rural people and farmers become “stupid,” a status that, on Heldke’s account, is worse than ignorant because “stupid people” are thought to be constitutionally incapable of knowing the right sorts of things because they know the wrong sorts of things . It seems reasonable, I suggest in this paper, to think that (...) contemporary urban agriculture movements can serve to mitigate the harms which Heldke argues arise from practices of stupidification. However, I argue that, insofar as such movements rely on and perpetuate the image of the Idyllic Farmer—an image constituted by early, romantic versions of agrarianism—they cannot serve this function. This is because the Idyllic Farmer, which is to agricultural ethics as the Ecological Indian is to environmental ethics, is both descriptively and prescriptively problematic. As such, any urban agricultural movement that takes this image as its guide—which, I argue, some important elements of the movement do—will not help to undermine stupidification and the harms it causes.

Climate change continues to have recognizable impacts across the globe, as weather patterns shift and impacts accumulate and intensify. In this wider context, urban areas face significant challenges as they attempt to mitigate dynamic changes at the local level — changes such as those caused by intensifying weather events, the disruption of critical supplies, and the deterioration of local ecosystems. One field that could help urban areas address these challenges is conservation biology. However, this paper presents the argument (...) that work in urban contexts may be especially difficult for conservation biologists. In light of current climate change predictions, conservation biology may need to abandon some of its core values in favor of commitments guiding urban ecology. More broadly, this essay aims to reconcile the goals of restoration and conservation, by reconceptualizing what an ecosystem is, in the context of a world threatened by global climate change.

A river can be the lifeblood of a city, standing as a symbol of economic prosperity, harmony with nature, and communal life, and the Menomonee River is such an anchor for the Milwaukee area. In Urban Wilderness, Eddee Daniel guides us down the waterways of the Menomonee watershed and reveals how preserving urban rivers is key to modern day city life. In rich color photographs and engaging text, Daniel explores the natural and cultural history of the Menomonee River. (...) The development and rapid growth of Milwaukee as one of the leading cities in the Midwest is deeply intertwined with the river, and Daniel reveals the river’s moods and ecological conditions and its ills and strengths. The book charts the exemplary preservation efforts to rescue the river from pollution and neglect, ultimately showing how parks and nature preserves are crucial to the quality of life and economic success of a thriving city such as Milwaukee. A compelling in-depth chronicle, Urban Wilderness is an invaluable read for environmental scholars, urbanists, and everyday citizens who are concerned about the environment. (shrink)

While we are currently experiencing a renaissance in philosophical work on agriculture and food ( Barnhill, Budolfson, & Doggett 2016 ; Thompson 2015 ; Kaplan 2012 ), these topics were common sources of discussion throughout the three-thousand-year history of Western thought. For example, the Ancient Greek philosopher Aristotle (2014 ) explored connections between fulfi lling human promise and systems of agriculture ( Thompson & Noll 2015 ) and Hippocrates (1923 ) stressed the importance of cultivating agricultural products provided by nature (...) ( Zwart 2000 ). In order to live a truly human life, Hippocrates argued, one must not passively consume crude food products, as such brutish living leads to terrible suffering. Later, both the Hebrew Bible and Christian Gospels provided clear ethical mandates concerning agricultural practices and the consumption of food. These mandates or ethics needed to be observed regardless of context ( Zwart 2000 ). More recently, Thomas Jefferson added to this literature, as he engaged in agricultural production at his Monticello plantation and wrote extensively on how farming is intimately connected to the political system of democracy ( Thompson & Noll 2015 ). This refl ection on food and agriculture continued into the 20th century, albeit not in the discipline of philosophy. Scientists and agricultural leaders, such as Henry Wallace and Liberty Hyde Bailey, provided important critiques of agricultural practices contemporary to their time. (shrink)

Sound and listening are intrinsically linked to how we experience and engage with places and communities. This guide invites landscape architects and urban designers to become soundscape architects and offers practical advice on sound and listening applicable to each stage of a design project: from reading the environment to intervening on it. This book foregrounds listening as an affective mediator between subjects and multispecies environments, and a vehicle to think and conceptualise environmental design beyond prevailing visual and human-centred modes. (...) The guide expands landscape architects' and urban designers' tools and skills to assess existing soundscapes, predict how those soundscapes will be altered through their designs, consider sound as a creative and active part of the design process, and envisage how users might perceive and be affected by those soundscapes as they evolve in time. The volume sits in the interface of research and practice, and incorporates theoretical, methodological and creative contributions from acoustic ecology, ecoacoustics, bioacoustics and sound art. Each of the design stages is illustrated through project examples that demonstrate the many advantages of incorporating attentive listening and sound into Landscape Architecture and Urban Design Practice. The book shows how incorporating listening and sounding as part of the design process promotes slow and subtle ways of practice, adds social and ecological value through the reduction of noise pollution and by monitoring the health of habitats, and enables the design of soundscapes that complement the character and design intent of a scheme and elicit joy and wonder. The book will be of interest to landscape architects, together with other design professionals such as urban designers, architects, geographers and engineers, who play a primary role in the composition of the soundscape.

Urban dwellers’ food and nutritional wellbeing are both dependent on infrastructure and can be indicative of wider wellbeing in urban contexts and societal health. This paper focuses on the multiple relationships that exist between food and infrastructure to provide a thorough theoretical and empirical grounding to urgent work on urban food security and nutrition in the context of rapid urban and nutrition transitions in the South. We argue that urban systems and food systems thinking have (...) not been well aligned, but that such alignment is not only timely and overdue but also fruitful for both thematic areas of research and policy. We draw in particular on work within wider urban political economy and political ecology that can be classified as part of the ‘infrastructural turn’ that is influential with urban studies but little acknowledged within food studies. Drawing on these literatures helps us to better understand the interrelationships between people, things and ideas that make up both infrastructure and food systems. Policy, planning and research relating to both food and urban systems cannot afford to ignore such interlinkages, though much policy still operates on the neat assumptions of progressive connectivity to ‘the grid’ and formal food retail. Instead we argue how in many urban governance systems, a variety of hybrid mechanisms—on and off the grid, public and private formal and informal—better represent how urban residents, particularly the most marginalised, meet their everyday food and infrastructural needs along a continuum of gridded and off-grid access.

Circular economy is a critical approach to realize the coordinated development of society, economy, and ecological environment. Given the fact that urban is a complex system in which human beings integrate material, energy, information, and natural environment and interact and influence each other, reviewing the urban circular economy research and development could benefit for having a better and comprehensive understanding on urban complexity. Mainly based on the Chinese literature studies from 1999 to 2020, this study aims to (...) present an in-depth analysis of the research themes, policy systems, and index system of Chinaʼs urban-scale circular economy, discuss the changes and evolution trends of themes, levels, and perspectives in time series, sort out the policy systems at both the national and local levels, and analyze the design principles and application fields of indicators. Finally, we propose that future development of an urban circular economy should be built based on modern techniques, technologies, and models. The construction of development mechanism on the circular economy should be framed as “government-led, market-driven, legal norms, policy support, technological support, and public participation” and inject concepts such as “Internet +,” “sharing economy,” “Internet of Things,” and “artificial intelligence.”.

This article considers the design and ideation of early modern Palermo’s urban waterscape, which traced the contours of a hybrid fluvial-maritime system surviving from antiquity. Framing the city’s port as a repository of collective memory and a site of self-construction, it questions how interventions undertaken between the fourteenth and seventeenth centuries - culminating in the ill-fated construction of the Molo Nuovo - recalibrated the interface between city and sea, and with it, Palermo’s identity. The port anchored the city’s cultural (...) and political ecologies, challenging the traditional divide between urban morphology and port planning. Using early modern Palermo as a guide, the article proposes a reinvestment in the interdisciplinary model of the urban waterscape, which regards water as a contested, socio-natural space. (shrink)

For achieving the sustainable development goals, green development has been raised to a high position for cities in China. The economic development in Northwest China is slow, the ecological environment is fragile, and the mineral resources are rich. Only through green development can we realize the comprehensive income of regional production development, rich life, and good ecology. This paper measures the green development efficiency of 30 prefecture-level cities in Northwest China by using DEA-SBM model of unexpected output, explores the (...) differences and causes of green development efficiency from the perspective of time and space through convergence coefficient, coordination matrix, GIS, and other methods, and empirically tests the impact of industrial structure, technological progress, and other driving factors on green development efficiency by using panel Tobit model. The results show that, on the whole, the efficiency of green development in Northwest China is low, path dependence is serious and unbalanced, the coordinated development effect of different regions is weak, and the spillover effect of core urban agglomerations has not been effectively exerted; from the perspective of driving factors, economic development, population density, traffic situation, and education investment can significantly improve the efficiency of urban green development, and the second is that the proportion of industries significantly hinders the improvement of green development efficiency, while the impact of scientific and technological innovation is not significant. Based on the empirical results, this paper believes that the harmonious development of natural environment and economic society can be realized only by improving the coordinated development effect among cities, implementing the optimization and upgrading of industrial structure, introducing excellent talents, and promoting the technological upgrading.

During the last years immigration has aggravated the socialproblems in many disadvantaged urban districts. High proportions of foreigners are concentrating in those areas which suffer from unemployment and bad housing conditions.

Though past commentators have attacked cities as corrupt, dirty places, it is almost too obvious to need stating that a sustainable future depends on them. This is because most people live in cities and because the streamlined use of urban space brings a wide range of efficiencies. Simultaneously, urban living and associated technologies may impact psychology such that people see humans and their cities as outside of nature, which has been shown to reduce concern for the wellbeing of (...) the planet. Exploring these points in the context of the COVID-19 pandemic, we speculate on psychologically fueled environmental consequences of remote technologies. One possibility is that they may diminish contact with what we colloquially call “nature,” thereby reducing concern for it. Another possibility is that remote technologies may promote personalized work rhythms, allowing people more time in the outdoors, amplifying concern for the environment. Recognizing that vulnerable segments of the population are currently excluded from this second option, we optimistically sketch scenarios in which technologies may—somewhat ironically—help humankind escape technological entrapment, freeing people from a variety of backgrounds to reconnect in caring ways with nature.

There are inconsistencies in the treatment and attitudes of human beings to animals and much confusion in thinking about what are appropriate conditions for using and keeping animals. This article outlines some of these considerations and then proposes guidelines for designing animal management systems. In the first place, the global and local ecological effects of all animal management systems must be considered and an environment designed that will not rock the biospherical boat. The main points to consider are the interrelatedness (...) of living things with each other and the environment, the self-sustaining nature of ecosystems, and the importance of diversity in the stability and maintenance of ecosystems. These can and should be taken into account when assessing animal management. They are illustrated by examples of companion/urban dogs, as well as farm, zoo, and circus animals. The environment must also be considered from the point of view of the ethological needs of the animals. There are two possible approaches to this: (1) the reductionist approach, illustrated by the choice experimental tests; and (2) a holistic, evolutionist approach that concentrates on the degree of behavioral restriction and the identification of distress. The assessment of an animal's ethological needs, and thus the ethological soundness of an environment, must take into account the species needs (communication system, species-specific characteristics of the brain receptors and cognition) and the individual's needs (his past experience). The behavioral effects of domestication and how distress can be assessed are discussed. Different ethical positions toward animals and their treatment are briefly outlined, and it is argued that, provided animals are in ecologically and ethologically sound environments, their use by human beings is ethically acceptable. The animal-human association should be characterized by symbiosis—mutual benefit—rather than a parasitic or exploitative relationship—employer to employee, rather than master to slave. (shrink)

An ecological study of the city is a new endeavor. Up to now, we have mostly been given inquiries dealing with transportation, housing, economic activity, recreational facilities, etc. All of this adds up to an attempt to reach partial solutions for problems affecting sub-systems. Urbanists and city planners have tried to reach a synthesis of these data whenever they were available.There is an ever increasing need to approach urban problems by borrowing the concepts and the methodology of ecology (...) The origins of this science stem from the research pertaining to plant and animal behavior in their natural habitat. Highly complex adaptation patterns could frequently be observed which allowed a large number of species not only to survive but also to attain a certain level of compatibility with other species. One need not be a determinist to recognize the common basis of adaptation for man and other animals and to tie together the physical and biological needs which underlie more complex individual and group behavior. Thus, for instance, von Frisch and Wilson - have recently redefined the biological bases of the noosphere. (shrink)

With increased urbanization, ecological challenges such as climate change and loss of biodiversity, and stress-related disorders globally posing a major threat to public health and wellbeing, the development of efficient multiple-use strategies for urban green spaces and infrastructures is of great importance. In addition to benefits such as climate and water regulation, food production, and biodiversity conservation, green spaces and features have been associated with various health and wellbeing outcomes from a psychological perspective. Research suggests links between exposure to (...) green environmental qualities and restoration from psycho-physiological stress and attention fatigue, promotion of physical activity, increased neighborhood satisfaction and even reduced mortality. Especially strong associations have been observed in urban and socio-economically challenged areas. Usually such salutogenic, i.e. health-promoting, effects are explained through theories related to the notion of biophilia, i.e. the idea that humans share innate tendencies to attend to natural environments and features that have been beneficial during evolution. This paper assumes an ecological approach to perception and behavior to be fruitful in order to analyze the salutogenic potential of environments such as urban green spaces and to step beyond the “green vs. gray” dichotomy that has been prevalent through much of the research on health-promoting environments. Through an analysis of environmental affordances for certain perceived qualities such an approach is explored through a proposed concept for urban green space use and management, the edible forest garden. Such gardens, based on agroecological principles, have emerged as one of the most promising models regarding ecologically sustainable food production. In addition to potential contributions of importance for urban sustainability and biodiversity, we argue that the inclusion of edible forest gardens in urban green spaces – today globally dominated by lawns – also potentially could reinforce several affordances of salutogenic importance, both in terms of e.g. social cohesion but also in regard to restoration from psycho-physiological stress and attention fatigue. Increased opportunities for contact with nature and processes of food production may also reinforce pro-environmental behaviors in the population and thus also affect long-term sustainability.

The author analyses an approach within the framework of urban sociology, characteristic to Chicago School. This approach combined certain biological premises in understanding the city with the typical sociological approach, seeing the city as a superorganism and a product of nature, which is why it is called the ecological theory of the city. In this regard, the connection between biology and sociology, as well as the theory of Robert Ezra Park and Ernest Watson Burgess, as typical representatives of this (...) sociological trend, will be the subject of special analysis, aiming to bring the reader closer to the ecological approach in urban sociology. The topic of particular interest is Park’s idea of the city as a product of nature, with symbiotic substructure and cultural superstructure, as well as Burgess’s idea of city growth and the theory of the concentric zones of city structure. Other issues of the ecological theory of the city were also analysed. (shrink)
