Most accounts of urban green space governance originate in cities where such initiatives have been successful. Meanwhile, there is too little information on cities where such initiatives develop with more difficulty. In order to overcome the problems that such cities face, their situations need to be studied more carefully to facilitate peer comparisons. This article provides an account of urban green space governance in three cities in Poland (Krakow, Lodz, Poznan), where environmental protection is still quite far down on the list of political priorities. With the use of a social network analysis we looked at the extent of relationships between different stakeholders and the roles of different actors within the network. The results indicate that the network's collaboration potential is barely used and that cross-sectoral collaboration is especially deficient. In particular, public institutions hold a relatively strong position and downplay the role of other actors. More collaboration is necessary and the potential bridging role of NGOs should be used to a larger extent. However, this requires more openness and trust within the network. 相似文献

Rural areas face increasing pressures to deliver both private and public goods from land management. Multiple stakeholders seek different outcomes and there is substantial heterogeneity in values. Trade-offs, synergies and complementarities exist between different services and alternative bundles of goods. The resulting complex social-ecological systems (SES) therefore require adaptive co-management. In a governance context, no single organisation has oversight across the variety of interests involved, but the challenge remains as to how these interests can best be balanced and negotiated, to deliver socially beneficial outcomes. This paper analyses how this might be achieved by considering the perspective of a ‘social residual claimant’ (SRC). The SRC, as an ideal type, represents the ultimate ‘owner’ or steward of an ecosystem which sets the criteria to assess alternative outcomes, identifying best approaches and addressing uncertainty through adaptive management. A SRC cannot be a static construct, but must interact with and influence private land-holders and other stakeholders, adjusting actions as circumstances change. We identify the criteria that would be required in order for an SRC to act in the best interests of society. We then make a comparison of these criteria against the conditions applying in three contrasting approaches currently operating in the UK: National Parks, Landscape Partnerships and Nature Improvement Areas. This enables us to identify the differences between approaches and to suggest changes that could enhance capabilities, as well as ideas for further research. We suggest that the ideal of an SRC offers a simple method of benchmarking that has potential application across a wider range of different local contexts, beyond the UK. 相似文献

Addressing the global challenges of climate change (CC), food security and poverty alleviation requires enhancing the adaptive capacity and mitigation potential of land use systems. To this end, Climate Smart Agriculture (CSA) aims to identify land use practices that sustainably increase productivity, enhance climate change (CC) adaptation and contribute to CC mitigation. A transition towards CSA requires technical, but also socio-institutional changes, for improved smallholder agricultural systems. Such changes may be triggered by stakeholder participation processes that stimulate social learning and collective action. This article evaluates whether a role-playing game (RPG) is an effective participatory tool to encourage social learning and collective action among local stakeholders towards adoption of CSA strategies. We designed and implemented an RPG with three groups of farmers in Apuí (Southern Amazonas), evaluating the game’s impact on social learning by interviewing each farmer before and after the RPG. Our findings show that the RPG induced not only technical learning, but also socio-institutional learning and engagement for collective action, though outcomes varied between different RPG sessions and among farmer participants. 相似文献

Environmental inequality scholarship has sought to shed light on the unequal environmental conditions borne by poor people and racial minorities, and to challenge public policies. Most studies are concerned either with assessing the unequal distribution of environmental amenities and disamenities or with exploring the theoretical foundations of environmental justice movements.We propose an original approach to environmental inequality, focused not only on the unequal distribution of environmental burdens but also on two other types of factors: the capacity to mobilize and engage in community organizations on the one hand and the spatial dimension of environmental inequalities on the other.The evidence for this study is from an opinion survey carried out in 2012 with 1298 individuals. We use a two-step cluster analysis method to compute a classification system based on four categories of variables: socio-economic, environmental, spatial, and social capital. 相似文献

This article investigates how a mix of energy-users from Denmark perceives energy and environmental issues such as the affordability of electricity and gasoline, the seriousness of climate change, and preferences for different energy systems. Its primary source of data is a pilot survey and energy literacy test distributed in English and Danish to 328 respondents spread across the country. The survey results are used to test four propositions about energy prices, being “green,” public knowledge and competence about energy issues, and self-sufficiency and sustainable technology. The data supports the propositions that Danes identify with “being green” and prefer national and local policies that endorse sustainable technology and being self-sufficient. However, the data also challenges the propositions that Danes would prioritize low energy prices and affordability as key energy concerns and that they are knowledgeable about energy and environmental issues. In this way, a problematic gap may exist between what many academic articles (and previous surveys) report Danish attitudes to be and what this study suggests they are. Given Denmark's ambitious low-carbon goals, these findings have clear relevance to other communities and countries seeking to decarbonize their own energy sectors. 相似文献

Human dimensions research focuses on the interrelationships between humans and the environment. To date, human dimensions
research in arctic regions has concentrated primarily on local events and contexts. As such, it complements analysis elsewhere
of adaptation and sustainable development within broad institutional, social, and environmental contexts. This paper reviews
five projects from the Human Dimensions of the Arctic System (HARC) initiative, established by the US National Science Foundation
in 1997. Common themes and findings are highlighted: climatic variations or change affect societies through interactions with
human activities; population dynamics provide key quantitative indicators of social impacts and well being; and specific impacts
and responses are the result of complex, context-sensitive interactions. Congruent approaches to the challenges of interdisciplinary
research are also identified: multivariate time plots aid the integration of data, retrospective and prospective studies are
part of a continuum and reinforce one another, comparative studies are essential for understanding general principles of human
dimensions, and arctic residents can play a vital role in research and action. 相似文献

While male parental care is uncommon in mammals, siamang (Symphalangus syndactylus) males provide care for infants in the form of infant carrying. I collected behavioral data from a cohort of five wild siamang
infants from early infancy until age 15–24 months to identify factors affecting male care and to assess the consequences of
male care for males, females, and infants in a population including socially monogamous groups and polyandrous groups. There
was substantial variation in male caring behavior. All males in polyandrous groups provided care for infants, but males in
socially monogamous groups provided substantially more care than males in polyandrous groups, even when the combined effort
of all males in a group was considered. These results suggest that polyandry in siamangs is unlikely to be promoted by the
need for “helpers.” Infants receiving more care from males did not receive more care overall because females compensated for
increases in male care by reducing their own caring effort. There was no significant relationship between indicators of male–female
social bond strength and male time spent carrying infants, and the onset of male care was not associated with a change in
copulation rates. Females providing more care for infants had significantly longer interbirth intervals. Male care may reduce
the energetic costs of reproduction for females, permitting higher female reproductive rates. 相似文献

Compared to terrestrial mammals, little is known of cetacean social systems as they are generally less accessible to behavioral
investigations due to their aquatic environment. The present study investigates group structure of the pelagic common dolphin,
Delphinus delphis, using genetic markers. Tissue samples from 52 individuals representing a recent live mass-stranding event were compared
to 42 single strandings taken from presumably different groups. The mass-stranding event occurred in 2002 on the French coast
of the English Channel, whereas the single strandings were collected between 1993 and 2003 along the western coast of France
(Bay of Biscay and English Channel). Analysis of mitochondrial DNA control region sequences indicated that genetic variability
within the mass-stranded pod was similar to variability observed in single strandings. The mass-stranded group was composed
of 41 different mitochondrial haplotypes or matrilines while the single strandings revealed 29 different haplotypes. Analysis
of 11 microsatellite loci revealed that average relatedness of the mass-stranded pod was not different from average relatedness
among all single strandings suggesting that individuals within the group had no closer kin relationships than animals taken
from presumably different groups. These results do not support a matriarchal system and suggest that common dolphins constituting
a pod are not necessarily genetically related. 相似文献
