Overview of Radioactive Waste Disposal at Sea

For hundreds of years, the seas have been used as a place to dispose of wastes from human activities. Although no high level radioactive waste has been disposed of into the sea, variable amounts of packaged low level radioactive wastes have been dumped at 47 sites in the northern part of the Atlantic and Pacific Oceans. in 1946 the first sea dumping operation took place at a site in the North-East Pacific Ocean. the last dumping operation was in 1982, at a site off the European continental shelf in the Atlantic Ocean. Between these two dates, an estimated 46 PBq (1.24 MCi) of radioactive waste coming from research, medical, military and industrial activities have been disposed of at sea. the present trend, through the Convention for the Prevention of Marine Pollution by Dumping of Wastes and other Matter and other Regional Conventions, points towards the prohibition of the dumping of any radioactive waste into the marine environment.     

国际环境保护公约中技术转让障碍问题的探讨

随着世界各国对全球资源与环境问题认识的逐步提高 ,发展中国家必将签署越来越多的国际环境公约 ,参与到国际环境保护合作中。尽管许多国际环境公约都明确规定了发达国家在资金和技术上支持发展中国家保护环境履行国际公约的义务 ,但是实际履约过程中技术转让的问题并未得到良好的解决。论文将讨论国际环境公约履约中的技术转让障碍问题 ,并以中国履行《关于消耗臭氧层物质的蒙特利尔议定书》 ,实施臭氧层保护行动过程中所存在的实际问题为例 ,对国际环境公约履行中技术转让障碍的原因及其后果进行分析 ,最后对发展中国家所应采取的立场和对策提出建议。

浅析国际环境公约对石油工业的影响

随着人类环境意识、资源意识的不断深化,越来越多的国家签署了国际环境公约。中国石油企业若要进一步参与国际化竞争,在环境保护方面就势必面临更大的挑战与压力。对气候变化框架公约、巴塞尔公约、湿地公约、海洋环境保护公约以及酸雨问题等与石油工业相关的国际环境公约进行了分析及探讨,以期为石油工业适应环境保护工作发展的需要及提高国际竞争力制定相应对策提供参考。     

Assessing London,Ontario's brownfield redevelopment effort to promote urban intensification

Intensification of existing urban areas is currently a major item on the policy agenda of the Ontario and Canadian governments. As part of the urban intensification drive, brownfield sites have become major candidates for redevelopment. Governments at all levels have initiated policies and programmes to encourage their remediation and redevelopment. This paper reports the findings of a qualitative exploration of brownfield redevelopment in London, Canada. Through in-depth interviews (n?=?17) with key stakeholders involved in brownfield redevelopment, the study explores the level of participation in brownfield redevelopment, barriers to brownfield redevelopment in the city, and perceptions about financial incentives in the city's Brownfield Community Improvement Plan. The study found that despite the availability of financial incentives, the overall private sector participation in brownfield redevelopment is low due to barriers such as competition from greenfield, risk, cost, negative public perception of brownfields, and complex remediation processes. The paper provides policy suggestions that may contribute to a more active participation in brownfield redevelopment in the city.     

浅析中国东海区海洋倾废管理现状与对策

实现对海洋倾废科学有效管理是保护海洋环境及海洋资源的一项重要内容和主要任务。东海是我国海洋生产力最大的海区,近年来,随着海洋经济和沿海区域经济的发展,向海上倾倒废弃物的数量和规模不断增加,在实际倾倒过程中出现了倾倒区选划利用不合理、违规倾倒和执法监管不力等问题,影响东海海洋生态环境平衡与可持续发展。因此,文章在对东海区海洋倾废活动现状进行全面客观梳理的基础上,就主要存在的问题进行实证分析,结合东海区海洋倾倒的实际需求,为实现合理有效的管理提出对策。

On causes of illegal waste dumping in Slovakia

This paper examines the determinants of illegal waste dumping at the county level in Slovakia (in 77 of 79 counties), using a truncated regression model. It analyzes a unique data-set composed of illegal dumping data provided by the TrashOut platform and sociodemographic data from the national statistical authority.

This study shows that a higher level of expected overall waste production results in a higher rate of illegally dumped waste and a higher number of illegal dumping sites. More precisely, income has a positive impact on the rate of illegal waste dumping, poverty influences the rate of illegal dumping negatively and a higher level of education does not result in more responsible waste management. On the contrary, higher education has a positive influence on the rate of dumping. A negative relationship between costs of illegal waste disposal and dumping rate, as well as a positive relationship between costs of legal waste disposal and dumping rate has been revealed.     

Are national biodiversity strategies and action plans appropriate for building responsibilities for mainstreaming biodiversity across policy sectors? The case of Finland

The Convention on Biological Diversity's national biodiversity strategies and action plans (NBSAPs) are major mechanisms for mainstreaming biodiversity into national policies. This article examines whether and how the NBSAPs contribute to mainstreaming biodiversity across policy sectors in Finland in order to halt biodiversity loss. We have developed an innovative analytical framework where the concept of responsibility addresses how motivations for mainstreaming can be built, and the concept of social learning outcomes addresses the extent of institutional changes for biodiversity. The Finnish NBSAP processes have been able to build diverse forms of responsibility (liability, accountability, responsiveness and care) in different policy sectors by providing new knowledge, careful process design and developing institutional linkages. Despite pro-biodiversity outcomes in the targeted policy sectors, the responsibilities do not diffuse from the environmental administration to other policy sectors to a sufficient extent. Closing this ‘responsibility gap’ is a key challenge for building effective environmental policies.
