Amenity migration: diverse conceptualizations of drivers,socioeconomic dimensions,and emerging challenges 总被引:7,自引:0,他引:7
Rural communities throughout the postindustrial world are in the midst of a significant transition, sometimes referred to
as rural restructuring, as traditional land uses, economic activities, and social arrangements transition to those associated
with “post-productivist” or “multifunctional” landscapes. Amenity migration, the movement of people based on the draw of natural
and/or cultural amenities, can be thought of as both driver and implication of this transition, resulting in significant changes
in the ownership, use, and governance of rural lands, as well as in the composition and socioeconomic dynamics of rural communities.
In concert with other social, economic and political processes, amenity migration is contributing to the fundamental transformation
of rural communities throughout the world. This paper presents a review of the social science literature related to the concept
of amenity migration, focusing on the ways in which it has been conceptualized, theorized, and documented by different communities
of scholars. We then profile and summarize diverse perspectives on drivers and socioeconomic impacts, highlighting emerging
challenges and opportunities related to this type of migration occurring at multiple scales and in multiple sites. The paper
also identifies and discusses particular areas where further research is needed. 相似文献

Collected sets of papers synthesizing data derived from the PIRLA project (Paleoecological Investigation of Recent Lake Acidification) will appear in coming issues of the Journal of Paleolimnology. This paper is designed to highlight these forthcoming papers, review the development and objectives of PIRLA, and acknowledge the many who have supported PIRLA in so many crucial ways.This is the first of a series of papers to be published by this journal which is a contribution of the Paleoecological Investigation of Recent Lake Acidification (PIRLA) project. Drs. D.F. Charles and D.R. Whitehead are guest editors for this series. 相似文献

Deep (> ~800 m) saline water-bearing formations in the United States have substantial pore volume that is targeted for storage of carbon dioxide (CO2) and the associated saline water can be extracted to increase CO2 storage efficiency, manage pressure build up, and create a new water source that, once treated, can be used for power-plant cooling or other purposes. Extraction, treatment and disposal costs of saline formation water to meet added water demands from CO2 capture and storage (CCS) are discussed. This underutilized water source may be important in meeting new water demand associated with CCS. For a representative natural gas combined-cycle (NGCC) power plant, simultaneous extraction of brine from the storage formation could provide enough water to meet all CCS-related cooling demands for 177 out of the 185 (96 %) saline formations analyzed in this study. Calculated total cost of water extraction, treatment and disposal is less than 4.00 US Dollars (USD) m?3 for 93 % of the 185 formations considered. In 90 % of 185 formations, treated water costs are less than 10.00 USD tonne?1 of CO2 injected. On average, this represents approximately 6 % of the total CO2 capture and injection costs for the NGCC scenario. 相似文献

Abstract The impact of animals upon the landscape, through such actions as trampling, feeding, burrowing, mounding, and dam building, is a topic of interest in university geography classrooms. However, the relatively fine‐scale nature of most such impacts precludes its examination via remote sensing. Nevertheless, remote sensing of many types of animal impact is possible, and in this paper I illustrate several such examples, primarily drawn from free‐access sites on the World Wide Web, using a variety of remote sensing platforms. Instructors of physical geography or resource/land use management courses can thus introduce a variety of remote sensing concepts and imagery types in their classrooms while at the same time examining the role of animals on the landscape. 相似文献

Abstract Today's Geography graduates are employed by a diverse set of employers, and the jobs these individuals fill are as varied as the field of Geography itself. Geographers who join corporate workplace teams may need to find common grounds for communication with their business school‐trained colleagues. This cross‐disciplinary study examines the curricula of introductory courses in Geographic Information Systems (GIS) and one of its business counterparts, Accounting Information Systems (AIS), through an analysis of GIS and AIS textbooks. The findings suggest that there are areas in which shared background exists. Introductory information about systems, and an understanding of database architectures are the most likely areas of commonality; depending on which GIS text was used during the geographer's training, the geographer may also share background in such areas as systems analysis, database management systems, and data modeling. 相似文献

Abstract The paper presents a geospatial modeling approach for the assessment of plant richness in Barsey Rhododendron Sanctuary in Sikkim, a Himalayan State of India located in the “Indo‐Burma” biodiversity hotspot. Remotely sensed data from Indian Remote Sensing Satellite IRS‐1C Linear Imaging Self‐Scanner (LISS‐III) and field‐based methods were synergistically used to model plant richness on 1:50,000 scale. It was found that the sanctuary is dominated by East Himalayan Moist Temperate Forest (55.50%), followed by Rhododendron Forest (23.77%), Degraded Forest (6.66%) and Hemlock Forest (0.78%). The vegetation map prepared through digital interpretation of satellite imagery was subjected to landscape analysis and assessment of biotic disturbance in terms of disturbance index. The disturbance index together with species richness, ecosystem uniqueness, total importance value and terrain complexity was modeled to assess the plant richness in this unique sanctuary. Out of the 120 km2 of the total geographical area of the sanctuary, 28.45 per cent was found to possess very high plant richness followed by high (50.84%), medium (6.96%) and low richness (13.75%). It was noted that plant richness assessment at ecosystem level presents a more realistic picture than at landscape level. The study demonstrated that remote sensing coupled with landscape analysis, ground inventory data and geospatial modeling holds good potential for rapid and operational assessment of plant richness. 相似文献

Abstract It is shown that in the limit of slow steady linearized flow and infinite stratification a stratified region lying above or below a layer of destabilized fluid produces zero velocity and zero stress boundary conditions. These novel boundary conditions constrain flow more fully than the more common rigid or free conditions, and arise because the penetrative flow in the stabilized region must pump only a finite amount of heat. 相似文献
