This paper reports on a quantitative estimation of the risk to residents at the toe of Mount Albino, a carbonatic relief covered by shallow deposits of pyroclastic soils, which threatens the municipality of Nocera Inferiore (southern Italy). The quantitative risk analysis (QRA) focuses on one type of mass transport phenomena typical for the context at hand, namely the hyperconcentrated flows. The methodological approach includes three main steps: hazard analysis, consequence analysis and risk estimation. Based on historical incident data, the hazard analysis makes use of a high-resolution digital terrain model and advanced models that incorporate relevant geological and geotechnical input data collected via in situ investigations and laboratory tests. The consequence analysis takes into account information on the exposed persons (age, gender) and their vulnerability. The estimated risk to life is calculated at the individual level (risk to the average and most exposed person). The reported procedure is one of the first QRA’s applications to instabilities which potentially affect natural slopes in Italy, and it was successfully used as technical basis for a public participatory process in Nocera Inferiore, designed and developed to support decisions about risk mitigation measures. 相似文献

Gated communities and other forms of privatized enclaves have become features of many cities. The rise of urban mixed-use enclaves, which integrate functions of work, entertainment and living, is a relatively new and understudied phenomenon that is expanding rapidly throughout the Global South. In this article, we advance the concept of enclave urbanism through a case study of Eastwood City in Metro Manila, the Philippines. We trace the enabling factors for mixed-use enclave creation and assess how the different functions are marketed and integrated in practice into one “live–work–play” development. Based on extensive qualitative research, we argue that the global capital accumulation strategy of real estate developers leads to a strong focus on production and entertainment functions, but neglects questions of liveability. We reflect on the implications of our findings for mega-urban regions and urban studies research. 相似文献

ABSTRACTThe development, integration, and distribution of the information and spatial data infrastructure (i.e. Digital Earth; DE) necessary to support the vision and goals of Future Earth (FE) will occur in a distributed fashion, in very diverse technological, institutional, socio-cultural, and economic contexts around the world. This complex context and ambitious goals require bringing to bear not only the best minds, but also the best science and technologies available. Free and Open Source Software for Geospatial Applications (FOSS4G) offers mature, capable and reliable software to contribute to the creation of this infrastructure. In this paper we point to a selected set of some of the most mature and reliable FOSS4G solutions that can be used to develop the functionality required as part of DE and FE. We provide examples of large-scale, sophisticated, mission-critical applications of each software to illustrate their power and capabilities in systems where they perform roles or functionality similar to the ones they could perform as part of DE and FE. We provide information and resources to assist the readers in carrying out their own assessments to select the best FOSS4G solutions for their particular contexts and system development needs. 相似文献

Considerable research has examined the social, cultural, economic, and community benefits of urban gardening. Few studies, however, have empirically assessed factors that influence urban community garden agrodiversity or its relationship to these dimensions of gardening. We conducted an interdisciplinary study of agrodiversity and cultural identity, based certain markers of identity, including how people see themselves with respect to race, ethnicity, or place of origin, in community gardens in Philadelphia, Pennsylvania. We conducted fifty‐six semistructured interviews with gardeners with different cultural identities in eight community gardens on their motivations for urban community gardening during 2014. We conducted plant inventories of the corresponding garden plots and found 104 cultivated edible and ornamental species and 28 varieties representing 34 families. We find that although gardens with culturally diverse gardeners did not have higher species richness, the cultural identity of the gardeners influenced species selection and reason for gardening. Further, the structure, design and species composition of garden plots reflected the identities of garden members. These finding have implications for the recent institutionalization of urban agriculture into city land policies in Philadelphia and other cities in North America. 相似文献

The Caribbean subspecies of the Red‐tailed Hawk (Buteo jamaicensis solitudinus or B.j. jamaicensis) is the largest native carnivore on the island of La Gonave, Haiti, and the island's apex predator. On other Caribbean islands, raptors have been persecuted by local people typically because of their depredation of livestock. In addition to possible persecution from humans, Red‐tailed Hawks on La Gonave face challenges from island‐wide timber overharvest and rapid land‐cover changes. To better understand the human‐apex predator relationship on La Gonave, we surveyed islanders about their perceptions of, and interactions with, the Red‐tailed Hawk. According to 121 respondents from 10 villages, La Gonavans do not hunt, kill, or consume Red‐tailed Hawks. Our study revealed a notable absence of negative perceptions of the hawk by respondents despite intense hawk depredation of domestic chickens. While the chicken depredation may lead outside observers to consider the human‐hawk relationship on La Gonave as representative of a human‐wildlife conflict, our interview data do not support that conception. Our findings reflect an important conversation in related contemporary scientific literature about what constitutes human‐wildlife conflicts across various cultures. Despite tolerance by residents, Red‐tailed Hawks on La Gonave remain threatened by habitat degradation. 相似文献
