The ascendance of the Pacific Rim is an indisputable global happening. North American geography, a logical leader in the study of this high profile phenomenon, has lagged behind other disciplines in Rim-focused research. This article argues in favor of a heightened Rim awareness, surveys recent publications, suggests promising Pacific Rim research directions, and proposes how the Association of American Geographers can help promote Rim studies. 相似文献

In the twenty-first century, there are three American Wests, which cut across cultural, political, physical, and economic boundaries. Parts of the West are booming, building homes, and adding population; others are legally off limits to such development; and much of the West has been bypassed by such development and growth. These are called here the Booming West, Protected West, and Bypassed West. Maps of climate, political boundaries, ethnic and racial identities, or presidential voting patterns do not match these three Wests. Each West has a different relationship to the others and might see them as threats or opportunities, and each West can be expected to grow in different areas at the expense of other Wests. The boundaries between the three Wests could be important locations; sharp transitions can exist between Wests, perhaps nowhere more so than where a fast growing metro area abuts a national park or forest boundary. Finally, the effects of climate change cut across the three Wests and have different implications for their future. Continued population growth will further emphasize the boundaries between each of the three Wests and raise the stakes for their control. 相似文献

Abstract A three-year institute called “The Lodge Pole River Project” was designed to change educator perceptions of American Indian historical geography and encourage the creation of balanced and culturally sensitive American Indian K-12 curriculum. This project offered unique opportunities to assess a geography institute's impact upon teacher knowledge and perceptions towards Native people and pedagogical approaches to teaching about American Indians and their landscapes. The assessment suggests that three weeks of field work, archival research, and curriculum writing increased participant knowledge of American Indian history and culture, solidified sympathetic perceptions and attitudes towards Native people, and strengthened the ability of educators to offer different interpretations of American Indian geography and history to their students. 相似文献

Seasonal and inter-annual relationships between vegetation and climate in central New Mexico, USA 总被引:8,自引:0,他引:8

Linear correlations between seasonal and inter-annual measures of meteorological variables and normalized difference vegetation index (NDVI) are calculated at six nearby yet distinct vegetation communities in semi-arid New Mexico, USA Monsoon season (June–September) precipitation shows considerable positive correlation with NDVI values from the contemporaneous summer, following spring, and following summer. Non-monsoon precipitation (October–May), temperature, and wind display both positive and negative correlations with NDVI values. These meteorological variables influence NDVI variability at different seasons and time lags. Thus vegetation responds to short-term climate variability in complex ways and serves as a source of memory for the climate system. 相似文献

Because medical geography is a dynamic and developing area of thought, a number of conceptual and empirical problems are, as yet, relatively unexplored. This essay constitutes an attempt to delimit these problems, which include the application of geographical analysis to ascertaining disease causation, the prediction of future disease patterns and disease diffusion, and evaluation of the importance of maximizing geographical access to health care facilities. 相似文献

Predictions of the death of impoverished and actively marginalized racial and ethnic communities are premature. Many core African American societies have been devastated by the state, capital, and cultural policies of the last two decades. Simultaneously, geography and the other social sciences have been mobilized in order to prevent a fuller understanding of these communities and of the need for social equity. The further development of several approaches is required to open geography and the other disciplines up for community‐building, rather than community destruction. The incorporation of research in the following areas holds out the promise of revitalizing both: human rights; the ethnic movements underlying restructuring; the social construction of regions; the reproduction of social power; building ethnic alliance; and indigenous knowledge systems. 相似文献

In 1994, a directed fishing moratorium was declared for Grand Bank American plaice (Hippoglossoides platessoides) and yellowtail flounder (Limanda ferruginea) stocks because both stocks showed severe declines in abundance from heavy exploitation during the mid 1980s and early 1990s. Four years later, the fishery for yellowtail re-opened while the plaice stock has shown little recovery and the moratorium is still in effect. To assess the possible causes of the differences in recovery between species, we examined the spatial structure and environmental characteristics of the continental shelf nursery habitats of plaice and yellowtail, and their relationship to recruitment variability and overall population size. Depth plays a major influential role determining the spatial pattern and the abundance of juveniles of both species and in the case of plaice the spatial structure of the adult population also determines the amount of nursery area utilised by juveniles. Recruitment variability was higher in plaice than in yellowtail. We found year class synchrony in both species indicating that common environmental conditions and/or biological processes are affecting recruitment in a similar manner. Density-dependent regulation appears to be more severe in yellowtail and this should contribute to a more stable population when compared to plaice. These results are discussed in terms of resiliency of both stocks to over-exploitation. 相似文献

For all its vitality political ecology often appears to be a project in which work by Anglo‐Americans in particular, if it is not privileged, certainly predominates. This trend reflects wider language and intellectual tendencies in human geography and the social sciences that distort the development of the field by downplaying or obscuring the contributions of many non‐Anglo‐Americans and by naturalizing Anglo‐American assumptions at the heart of research. The latter in turn determine what constitutes ‘good’ work – even as there is no single definition of political ecology. Arguing against this tendency, this paper draws on postcolonial thinking to emphasize the need to reassess and reorient the field as ‘other’ political ecologies are feasible and desirable. 相似文献
