National parks are the keystone institutions of environmental conservation. Because national parks make certain lands part of the state itself, international agencies and nongovernmental organizations that promote national parks propose, in effect, to alter the state, as well as the local economy and state relations with social groups. Has international political pressure caused states to create national parks? I consider whether countries highly involved in international politics have the largest proportions of land in national parks. I conclude that many states create minimal park systems as symbolic gestures to the international community. Field researchers may find it easier to explain the success or failure of parks if they identity why state officials decide that adopting international conservation norms will enhance state authority over people and state sovereignty over land.  相似文献

It is widely recognized that developing countries lack technical and institutional capacity to effectively implement genetic resources policy. This has led Bioversity International (the then IPGRI) to initiate a project called Genetic Resources Policy Initiative (GRPI) in six countries (Ethiopia, Egypt, Zambia, Peru, Vietnam and Nepal). Drawing from the literature and experiences of this project, this paper has attempted to document some of the lessons from the project and present the issues and challenges that need to be addressed for effective genetic resources policy. Recognizing its cross-cutting nature, the paper has argued that genetic resources policy has to be part of the broader development agenda to effectively deal with trade-offs and harmonize the conflicts. Essentially, the important policy question is to strike the balance and simultaneously promote the diversity of genetic resources and welfare outcomes. The major thrust of GRPI has been the multi-disciplinary, -sectoral, and -stakeholder (3M) approach. Despite all its theoretical merits, its implementation has been a serious challenge in practice. This has, among others, been due to ‘‘A project for all is a project for none’’ dilemma. Engaging decision makers in 3M deliberations has revealed that many of them tend to think that maintaining genetic diversity promotes traditional farming and retards agricultural development. Clearly, addressing each of these challenges and policy loopholes requires innovation in a diversity of institutions.  相似文献

Yellowstone National Park poses critical issues in biology and philosophy. Among these are (1) how to value nature, especially at the ecosystem level, and whether to let nature take its course or employ hands-on scientific management; (2) the meaning of natural as this operates in park policy; (3) establishing biological claims on th scale of regional systems; (4) the interplay of natural and cultural history, involving both native and European Americans; (5) and sociopolitical forces as determinants in biological discovery. Alston Chase's strident Playing God in Yellowstone is critized and used as a test of David Hull's naturalistic philosophy of biology. Biology and philosophy in Yellowstone ought to combine for an appropriate environmental ethic.The author thanks Donald A. Crosby, Jann Benson, Tom Wolf, William W. Dunmire, Norman A. Bishop, and Paul Schullery for critical help.  相似文献

The protected areas of Bolivia cover 10.2% of its territory, but only 60% of this surface is considered to be of conservation value. Protected areas are unevenly distributed over the eight phyto-geographic regions of Bolivia. The Pantanal is not represented in any conservation unit. Inventories and basic information are usually lacking as plant surveys have been carried out mostly outside protected areas.  相似文献

The debate on the link between ethnicity and violence has been raging in political science literature since the end of the Cold War. Often, cross-country quantitative studies dismissed the importance of ethnic heterogeneity as a source of violent conflict. How the patterns of ethnic settlement within a country affect the severity of violence, though, has not yet been studied through similar techniques. In this essay, we build and analyse a data set of major violence-related variables collected at the local level during the 1992–1995 war in Bosnia-Herzegovina. What emerges is that the local distribution of the population, in terms of the number and relative size of the groups, is a key factor in explaining the intensity of violence in the Bosnian municipalities.  相似文献

Ecosystem health through ecological restoration: barriers and opportunities   总被引:7,自引:0,他引:7  
It is quite possible that no ecosystem on the planet is totally free of anthropogenic effects. Changes in the ozone layer, airborne transport of contaminants, and the persistence of pesticides and other chemicals, coupled with biological magnification, implies that even remote areas are probably not comparable to their condition before the industrial revolution and the recent explosion of human population. Theoretical ecologists have attempted to isolate their theories and studies from anthropogenic effects with varying degrees of success. However, finding ecosystems free of the effects of human society is becoming increasingly difficult, partly because of the global nature of pollution problems. Regrettably, many academicians are not educated in policy development as they work toward B.S., M.S., or Ph.D. degrees in the sciences. As a consequence, scientists are surprised to learn that a politically-appointed individual, experienced in law or some other non-scientific field, usually has final decision-making authority over policy that affects ecosystems. Scientists must understand that policy links science to social, economic, and legal societal values and needs. Finally, aside from the fact that policy or lack thereof now affects all of the planet's ecosystems, policy most likely will also determine which areas of research are funded. While some scientific studies could be carried out with personal funds, these are not particularly common in mainstream science and, therefore, obtaining financial support for ecosystem studies for the remainder of this century and probably early in the next will depend increasingly on societal policy other than purely science policy.  相似文献

Contractual national parks in South Africa are established on land owned either by the state or by a group of private individuals, but managed by South African National Parks (SANP) according to the terms of a joint management agreement drawn up by a joint management committee consisting of representatives from SANP and the landowners. Since majority rule in 1994, contractual national parks have been seen as a model through which the country's conservation as well as development objectives can be met, particularly where landowners are previously disadvantaged communities. This study looks at the Makuleke region of Kruger National Park in order to ascertain how successful the contractual national park model is in meeting conservation, social, and economic objectives for the area.  相似文献

This article explores the obstacles to crafting comprehensive policies for ethnic minorities within the Soviet successor states. It focuses on a case that has been viewed as a model for the peaceful resolution of ethnic conflict in the region: Moldova's devolution of power to its small Gagauz (Christian Turkic) minority. The relationship between the Moldovan government and the Gagauzi reached its nadir in 1990, when Moldovan volunteer forces and Gagauz irregulars stood at the brink of all‐out civil war over the issue of a separate Gagauz political entity. Since then, however, Moldova has created a special administrative unit known as Gagauz Yeri ('the Gagauz land'). In contrast to other ethno‐territorial disputes in the former Soviet Union, the Gagauz case has illustrated that a range of policy options exists between the extremes of maintaining a highly centralized, unitary state structure and the devolution of authority to loosely related confederative units.  相似文献

Wolves (Canis lupus), a once widely distributed species, were systematically removed from many temperate zone ecosystems due to conflicts with humans. A change in human attitudes and cultural norms has brought about a recovery in some suitable areas, yet reintroductions are still controversial. Two notable reintroduction areas in the United States were Yellowstone and Isle Royale National Parks. Both proposals caused polarization and debate. In Yellowstone opposition focused on outside the park effects, mainly wolves killing livestock and wild game also desired by human hunters. At Isle Royale, opposition was mostly about human interventions into nature and impairment of wilderness values contrary to the spirit of 1964 Wilderness Act. Both locations had periods in the 20th century with and without wolves and the presence of wolves had a dampening effect on ungulate population fluctuations. Most outcomes of reintroduction at Yellowstone were predicted as the Environmental Impact Statement written beforehand correctly predicted 78% of the 51 outcomes that were examined. Wolves were too recently reintroduced to Isle Royale to make similar comparisons, but we conclude that intervention is not contrary to the Wilderness Act, nor author Howard Zahniser's vision, partially because wolf reintroduction was a mitigation for human actions. Also, not intervening, or inaction, often perceived as safer, would have had more damaging impacts to ecosystem functioning.  相似文献

ABSTRACT

This article looks at the communal violence in Ambon, Poso, and Sambas in post-Suharto Indonesia from a comparative perspective. It explores why Ambon and Poso were seen as religious while Sambas was seen as ethnic despite the fact that in all three conflicts different religions and ethnicities fought each other. Examining the “ethnic” elements, this article advances three arguments: First, that the Poso and Ambon conflicts were no less ethnic than the Sambas conflict as they had similar “ethnic causes”. Second, that the religious narrative dominated in Ambon and Poso because it reflected the Islamic resurgence in Indonesia since the 1990s while the narrative in Sambas reflected that it was the latest round of a pre-existing anti-Madurese conflict which had already been “defined” as “ethnic”. Third, that the narratives were framed strategically, thus influencing the trajectory of the conflict but also responding to it.  相似文献

Spillover impacts pose challenges for the management of protected areas (PAs). The issue of external threats encroaching on PAs has long been recognized, but a corollary—that PA conservation can increase costs borne by neighboring governments or landowners—is less well appreciated. In some contexts, basic principles of fairness and cooperation suggest that PA users should help pay these costs. Several countries have developed mechanisms for distributing the costs of spillover impacts to PA users, but not the United States. Here, we investigate whether and how US park visitors could help address one type of spillover, the need for wildlife conservation efforts beyond park boundaries, using a case study of the Greater Yellowstone Ecosystem (GYE). We examine a “conservation fee” recently proposed in the Wyoming legislature, along with tax-based alternatives. After exploring some costs of wildlife conservation in GYE, we estimate that a fee of up to $10 per vehicle could generate up to $13 million annually, and tax-based approaches considerably more. We consider legal, political, and governance challenges, and ways to mitigate them. The GYE could serve as a demonstration site for visitor funding of cooperative, large-landscape conservation, for potential future expansion in the US and beyond.  相似文献

Ultraviolet-B radiation (UV-B, 280–320-nm wavelengths) doses were estimated for 1024 wetlands in six national parks: Acadia (Acadia), Glacier (Glacier), Great Smoky Mountains (Smoky), Olympic (Olympic), Rocky Mountain (Rocky), and Sequoia/Kings Canyon (Sequoia). Estimates were made using ground-based UV-B data (Brewer spectrophotometers), solar radiation models, GIS tools, field characterization of vegetative features, and quantification of DOC concentration and spectral absorbance. UV-B dose estimates were made for the summer solstice, at a depth of 1 cm in each wetland. The mean dose across all wetlands and parks was 19.3 W-h m−2 (range of 3.4–32.1 W-h m−2). The mean dose was lowest in Acadia (13.7 W-h m−2) and highest in Rocky (24.4 W-h m−2). Doses were significantly different among all parks. These wetland doses correspond to UV-B flux of 125.0 μW cm−2 (range 21.4–194.7 μW cm−2) based on a day length, averaged among all parks, of 15.5 h. Dissolved organic carbon (DOC), a key determinant of water-column UV-B flux, ranged from 0.6 (analytical detection limit) to 36.7 mg C L−1 over all wetlands and parks, and reduced potential maximal UV-B doses at 1-cm depth by 1%–87 %. DOC concentration, as well as its effect on dose, was lowest in Sequoia and highest in Acadia (DOC was equivalent in Acadia, Glacier, and Rocky). Landscape reduction of potential maximal UV-B doses ranged from zero to 77% and was lowest in Sequoia. These regional differences in UV-B wetland dose illustrate the importance of considering all aspects of exposure in evaluating the potential impact of UV-B on aquatic organisms.  相似文献

Social, economic, and environmental restorations are important concerns in mine rehabilitation programs. Nonetheless, limited attention has been given to the social and economic evaluation of mine rehabilitation programs in developing countries with fast‐growing economies and large populations. To evaluate the social, economic, and environmental sustainability of mine communities before and after mine rehabilitation programs, we placed the study in China, which has experienced large‐scale mine closures resulting from resource depletion. By adopting an integrative model, sustainability cube, we evaluated social, economic, environmental, and overall sustainability (the combination of social, economic, and environmental) of its mine rehabilitation program—the national mine parks (reengineering closed mines as tourist parks, which constitutes the mine rehabilitation program) at the community level before and after the park establishment. Our results indicate that the implementation of national mine parks has improved the overall sustainability of local communities; the sustainability scores of the economic and environmental sectors increased significantly, while the sustainability score for the social sector decreased (mainly due to increased emigration after mine shutdown). We provide suggestions to improve social sector performance in mine rehabilitation programs, aiming to further enhance overall sustainability after mine closure.  相似文献

In recent decades conservation biology has achieved a high position among the sciences. This is certainly true of South Africa, a small country, but the third most biodiverse in the world. This article traces some aspects of the transformation of South African wildlife management during the 1930s to the 1960s from game reserves based on custodianship and the “balance of nature” into scientifically managed national parks with a philosophy of “command and control” or “management by intervention.” In 1910 the four British colonies had formed the Union of South Africa, and by the 1920s there was wide acceptance of national parks, a development influenced by their success in the United States. It was not, however, until after the Second World War, that management of the expanding conservation estate altered from a rather unsystematic laissez faire variety, into more scientifically informed management practices with an efficient bureaucracy in charge. This was achieved by modifications in organizational structures and institutional cultures initiated by a change of government in 1948 which, this article argues, impacted in turn on wildlife management and shaped and professionalized many aspects of that field science. “Management by intervention” was the hallmark of South African wildlife and conservation biology from the 1960s until recently, when there have been shifts towards “adaptive resource management” in a period of further change in the country’s politics.  相似文献

This article argues that the political accommodation of ethnic groups is a major determinant of ethnic violence and its effects vary depending on the pre-existing levels of mobilization. Accordingly, civic assimilationism is the most effective ethnic incorporation mode in terms of ensuring that weakly mobilized ethnic groups remain peaceful. Liberal multiculturalism is most effective in terms of eliciting peaceful mobilizations from highly mobilized ethnic groups. The ethnocratic mode tends to be the most conducive to violent mobilization at both low and high pre-existing mobilization levels. The theory is explored through case studies of Turks in Bulgaria and Cyprus. By demonstrating how the effects of ethnic incorporation policies vary depending on pre-existing mobilization levels, the article also challenges previous assumptions about the relationship between political opening and ethnic mobilization. Such an account not only explains the political determinants of ethnic violence, but also indicates potential political remedies to such problems.  相似文献
