以生态文明示范建设促进阿坝州可持续发展

阿坝州是长江、黄河上游的重要生态屏障和水源涵养区,在成都经济圈、长江经济带乃至全国具有重要的生态地位。拟在分析阿坝州生态文明建设的优势和面临的问题基础上,提出面对生态环境保护与区域发展的双重压力,阿坝应通过大力推动生态文明示范建设,加大生态环境保护力度,促进经济发展方式转变。坚持生态资源产业化与产业生态化的有机融合,大力发展生态旅游业、生态农牧业、生态工业,促进阿坝州经济、社会、生态环境3者的协调发展。     

阿坝州生态补偿实施现状分析及政策建议

实施生态保护补偿是调动各方积极性、保护好生态环境的重要手段,是生态文明制度建设的重要内容。近年来,中央和四川省帮助阿坝州有序推进生态保护补偿机制建设,深入实施重点生态功能区转移支付、森林生态效益补偿、草原生态保护补助奖励、湿地生态效益补偿等一批生态补偿政策,取得了阶段性进展,对全州生态保护、经济发展、民生改善、社会稳定等发挥了重要作用。但总体看,阿坝州仍存在生态补偿范围偏小、标准偏低,保护者和受益者良性互动的体制机制尚不完善的问题,一定程度上影响了生态环境保护措施的成效。因此,为进一步健全生态保护补偿机制、使生态补偿政策更好的发挥作用,研究深入梳理了阿坝州生态补偿现状,分析了生态补偿存在的问题和困难,并提出了健全生态保护补偿机制的建议。旨在更好践行习近平生态文明思想和“绿水青山就是金山银山”绿色发展理念,从而加快推进阿坝州生态文明建设和川西北阿坝生态示范区建设,进而实现区域协调和高质量发展。

Levels of lead in blood in residents of Kuwait

Following an examination of blood samples from 1000 persons from Kuwait, a number of important differences in the levels of lead in the blood were noted. There were significant differences between the sexes living in the same residential area. Certain significant lead in blood differences were also found between females and males who dyed their hair, and between smokers and non-smokers. Lead in blood concentrations were also tested for the various blood groups of the respondents. It was noted that O⁺ blood group respondents were found to have higher lead levels than those of other major blood groups.     

Assessment of flooding impacts in terms of sustainability in mainland China

An understanding of flood impact in terms of sustainability is vital for long-term disaster risk reduction. This paper utilizes two important concepts: conventional insurance related flood risk for short-term damage by specific flood events, and long-term flood impact on sustainability. The Insurance Related Flood Risk index, IRFR, is defined as the product of the Flood Hazard Index (FHI) and Vulnerability. The Long-term Flood Impact on Sustainability index, LFIS, is the ratio of the flood hazard index to the Sustainable Development Index (SDI). Using a rapid assessment approach, quantitative assessments of IRFR and LFIS are carried out for 2339 counties and cities in mainland China. Each index is graded from ‘very low’ to ‘very high’ according to the eigenvalue magnitude of cluster centroids. By combining grades of FHI and SDI, mainland China is then classified into four zones in order to identify regional variations in the potential linkage between flood hazard and sustainability. Zone I regions, where FHI is graded ‘very low’ or ‘low’ and SDI is ‘medium’ to ‘very high’, are mainly located in western China. Zone II regions, where FHI and SDI are ‘medium’ or ‘high’, occur in the rapidly developing areas of central and eastern China. Zone III regions, where FHI and SDI are ‘very low’ or ‘low’, correspond to the resource-based areas of western and north-central China. Zone IV regions, where FHI is ‘medium’ to ‘very high’ and SDI is ‘very low’ to ‘low’, occur in ecologically fragile areas of south-western China. The paper also examines the distributions of IRFR and LFIS throughout mainland China. Although 57% of the counties and cities have low IRFR values, 64% have high LFIS values. The modal values of LFIS are ordered as Zone I < Zone II ≈ Zone III < Zone IV; whereas the modal values of IRFR are ordered as Zone I < Zone III < Zone IV < Zone II. It is recommended that present flood risk policies be altered towards a more sustainable flood risk management strategy in areas where LFIS and IRFR vary significantly, with particular attention focused on Zone IV regions, which presently experience poverty and a deteriorating eco-system.

Closure of Disputes in Assessments of Climate Change in The Netherlands

2 greenhouse gases in assessment studies. For the cases studied, we identify variability in the assessment reports in the Netherlands during the pre-IPCC period. In the Netherlands arena, the assessments in this period can be seen as exponents of two different lines, a Netherlands line and an international line. We seek to identify what factors were decisive in the selection processes that resulted in the closure of visible disputes (visible in or across the assessment reports) for both cases. Our analysis reveals a remarkable difference in the adoption behavior of two Dutch assessment groups despite a large overlap in membership. We provide evidence that it is not the paradigmatic predisposition of the experts in the committee that was decisive for the closure of visible disputes, but it was the context in which the experts operated and the commitments they had made in each setting.

Role of Wild Game in the Diet of Recreationists in South Carolina

Risk assessors have devoted considerable attention to the consumption of fish in the diet of recreational and subsistence anglers, but little attention has been directed toward the percentage that wild game contributes to total protein intake for people who engage in hunting and fishing. While recall studies have limitations, the relative errors should be similar for different types of fish and game. We interviewed 454 people attending the Palmetto Sportsmen's Classic in South Carolina to determine their consumption patterns of domesticated animals, fish (both wild-caught and commercial) and wild game. The percentage of people who consumed each type of meat was: chicken (98%); beef (95%); wild-caught fish (79%); deer (79%); restaurant fish (73%); pork (71%); dove (47%); commercial fish (41%); wild turkey (40%), duck, squirrel and self-caught quail (about 25% each); restaurant quail (10%); and raccoon (11%). Although a similar proportion of white respondents and black respondents consumed wild game overall (90%), there were ethnic differences in the number of meals of wild-caught fish and game. Black respondents ate more wild-caught fish, rabbit, raccoon and squirrel, and less deer, than did white respondents. Wild-caught fish and game made up 50% of the meat and fish diet of black sportsmen, but only 32% for whites. Wild-caught fish and game were being eaten disproportionately more by low-income black respondents, while more deer was consumed by higher-income black respondents. The data suggest that managers and planners should take into account age, ethnicity and income when (1) conducting exposure assessments, (2) considering consumption patterns for wild-caught fish and game and (3) managing risk from wild-caught fish and game. The data will be especially useful to policy makers and risk managers who are designing consumption advisories, for risk communicators in identifying the target audience and for managers designing long-term stewardship for sites with contamination.
