科技进步改进了人类对天然生物危害因子的操控能力,在诱发新的生物安全危害形态的同时,也赋予了生物安全客体的源头难以追溯性、生物安全主体的多元性、生物安全危害演变机理的复杂性等特点。生物安全在很大程度上体现了非传统安全的非传统特点。随着生物科技与生物安全在推动人类社会发展进程的作用日益显著,21世纪或将成为生物安全的时代。新一轮生物科技变革及其与人类社会互动衍生的生物安全问题,已经逐渐触及人类安全观念和现代文明的内源性危机或挑战。全面提升国家生物安全能力、优化国家生物安全治理,不仅是世界各国的战略选择,也是对人类科技文明与政治文明的新探索。  相似文献

Land‐use changes and the expansion of protected areas (PAs) have amplified the interaction between protected and unprotected areas worldwide. In this context, ‘interface processes' (human–nature and cross‐boundary interactions inside and around PAs) have become central to issues around the conservation of biodiversity and ecosystem services. This scientific literature review aimed to explore current knowledge and research gaps on interface processes regarding terrestrial PAs. At first, 3,515 references related to the topic were extracted through a standardized search on the Web of Science and analyzed with scientometric techniques. Next, a full‐text analysis was conducted on a sample of 240 research papers. A keyword analysis revealed a wide diversity of research topics, from ‘pure' ecology to sociopolitical research. We found a bias in the geographical distribution of research, with half the papers focusing on eight countries. Additionally, we found that the spatial extent of cross‐boundary interactions was rarely assessed, preventing any clear delimitation of PA interactive zones. In the 240 research papers we scanned, we identified 403 processes that were studied. The ecological effects of PAs were well documented and appeared to be positive overall. In contrast, the effects of PAs on local communities were understudied and, according to the literature focusing on these, were very variable according to local contexts. Our findings highlight key research advances on interface processes, especially regarding the ecological outcomes of PAs, the influence of human activities on biodiversity, and PA governance issues. In contrast, main knowledge gaps concern the spatial extent of interactive zones, as well as the interactions between local people and conservation actions and how to promote synergies between them. While the review was limited to terrestrial PAs, its findings allow us to propose research priorities for tackling environmental and socioeconomic challenges in the face of a rapidly changing world.  相似文献

陆地生态系统是地球生物圈系统的核心组分,是人类生活、生产及社会经济活动的场所。然而,人类文明发展和科学技术进步在不断地扩大对资源的利用规模和强度,也导致了严重威胁社会可持续发展的全球气候变化、生物多样性丧失、环境污染、资源枯竭、生态系统退化等环境问题。社会公众期望生态学研究能够为区域、大陆及全球尺度的生态系统的利用和保护、维持人类社会可持续发展提供科学理论及系统性的解决方案。本研究以服务中国生态文明建设、生态安全格局构建、区域生态环境治理,以及宏观生态系统科学发展为目标,回顾了中国的区域生态环境治理成效及经验;分析了我国生态文明建设对大尺度生态系统科学研究的科技需求与时代特征,提出了利用基于自然的宏生态系统途径的新思路提升区域生态环境治理及安全格局构建的设想。在此基础上,讨论了中国的大尺度区域安全格局构建及生态环境治理的新思路、战略布局、技术途径与科技支撑体系,为中国安全、健康和美丽的国土空间利用及生态文明建设进步提供理论参考。  相似文献

Biobanks are collections of human biological tissue used for genomics research. This promises a better understanding of the gene-based contribution to common disease and development of a more personalized approach to healthcare with safer drugs and more effective treatment. However, biobanks are also controversial owing to the ethical, legal, social and political issues raised about their collection and use of biological samples. Therefore, their democratic governance is not only a normative challenge but also an empirical one. This paper is concerned with both challenges: it attempts to “evaluate” processes of democratic governance of genomics by focusing on the case of UK Biobank. The overall argument is that although the UK Biobank performs well in terms of general democratic governance structures, there are epistemological and practical limits to specific democratic governance processes.  相似文献

The attacks on the Twin Towers in New York in September 2001 and subsequent events not only ignited a ‘war on terror’, but also marked a crucial change in the policies on integration of migrants of Islamic background in Europe. Most countries departed from integration policies based on some sort of recognition of cultural diversity and emphasized national culture as the only legitimate format for citizenship. The result is a strengthening of a frame of governance with the aim to regulate Islamic practices and to mould outlooks, institutional settings and legal arrangements into the nation-state format. This has been referred to as the ‘domestication of Islam’. One of the consequences is the narrowing down of research agendas and academic knowledge production. In this article I explore this process and address important fields of study that tend to be neglected in the study of Islam in Europe.  相似文献

A considerable amount of recent work in political science and economics builds from the hypothesis that ethnic heterogeneity leads to poor provision of public goods, a key component of poor governance. Much of this work cites Alesina, Baqir and Easterly as providing empirical proof. This paper argues that the findings of this article have been significantly overstated. Through a simple re-analysis of the data, it shows that ethnic diversity does not straightforwardly undermine public goods provision. Rather, at least in these data, the relationship is mixed for different public goods: ethnic diversity is related to lower provision of some public goods and to higher provision of others. In some cases, there is no clear relationship. The differences between the findings presented here and those of the original article are arguably subtle, but are worth noting because of Alesina, et al.'s important contribution to the literature.  相似文献

Hanchard’s Spectre of Race is an important and far-reaching piece of scholarship that makes important contributions to the field of poltiical science and to our understandings of democracy, statecraft and the construction and management of difference. This article analyzes the strengths of Hanchard’s comparative methodology while also raising a number of questions about the nature and functioning of racial regimes. First, it asks where capitalist development generally, and material relations and struggles more specifically, are in hanchard’s theory of race, democracy and statecraft. More specifically, it calls for engagement with the historic, but recently revived school of studies in racial capitalism to think critically about the logic of racial states and their different manifestations. Second, the article raises a number of questions about the coherence of racial regimes, across arms of the state, across time, and across different groups.  相似文献

With the increasing use of the oceans and coastal areas, there is a need to pay greater attention to and reexamine the issue of ocean governance. Through comparing the framework of ocean governance in mainland China with that in Taiwan in terms of legislation, administration, and law enforcement, this article establishes that there are advanced practices concerning ocean governance in Taiwan and lessons that may be applicable for mainland China.  相似文献

Increasing production of biofuels has led to concerns about indirect land‐use change (ILUC). So far, significant efforts have been made to assess potential ILUC effects. But limited attention has been paid to strategies for reducing the extent of ILUC and controlling the type of LUC. This case study assesses five key ILUC mitigation measures to quantify the low‐ILUC‐risk production potential of miscanthus‐based bioethanol in Lublin province (Poland) in 2020. In 2020, a total area of 196 to 818 thousand hectare of agricultural land could be made available for biomass production by realizing above‐baseline yield developments (95–413 thousand ha), increased food chain efficiencies (9–30 thousand ha) and biofuel feedstock production on underutilized lands (92–375 thousand ha). However, a maximum 203–269 thousand hectare is considered legally available (not protected) and biophysically suitable for miscanthus production. The resulting low‐ILUC‐risk bioethanol production potential ranges from 12 to 35 PJ per year. The potential from this region alone is higher than the national Polish target for second‐generation bioethanol consumption of 9 PJ in 2020. Although the sustainable implementation potential may be lower, the province of Lublin could play a key role in achieving this target. This study shows that the mitigation or prevention of ILUC from bioenergy is only possible when an integrated perspective is adopted on the agricultural and bioenergy sectors. Governance and policies on planning and implementing ILUC mitigation are considered vital for realizing a significant bioenergy potential with low ILUC risk. One important aspect in this regard is monitoring the risk of ILUC and the implementation of ILUC mitigation measures. Key parameters for monitoring are land use, land cover and crop yields.  相似文献
