Considerable importance is attached to the role of the public in environmental matters as consumers, investors, lobbyists and electors. To involve the public in safeguarding the environment it is necessary to capture their interest and to inform them. This paper assesses the contribution of registers of environmental information as one way of informing the public. It draws together the findings of three separate pieces of research into the use of public registers (including water registers, planning registers, local air pollution control registers and waste registers) undertaken in the last seven years. The registers are assessed in terms of their contribution in promoting public reassurance, agency accountability, industrial responsibility and public participation. 相似文献

This article critically reviews environmental assessment (EA) practices in Sri Lanka, with a particular focus on ecology.
An overview is provided of the domestic and international influences which have shaped the administrative process which is
currently a two-tiered scheme. An Initial Environmental Examination (IEE) provides a preliminary screening tool, prior to
the requirement for a full Environmental Impact Assessment (EIA). A comprehensive survey of Sri Lankan national archives showed
that 463 EAs were completed in the period 1981–2005, with the bulk of these in the more populated Western and North Western
Provinces. Two-thirds were IEE surveys, while the remaining third advanced to full EIA. A representative sample of 130 EAs
(both IEEs and full EIAs) spanning a broad range of project types, scales, and environmental settings was selected to evaluate
the quality of the ecological investigations within the published environmental impact statements (EISs). These were assigned
into five classes of “explanatory power”, on the basis of their scientific content in relation to survey, analysis, and reporting
of ecological interests. Within most EISs, the ecological impact assessment (EcIA) was restricted to the lowest two categories
of ecological assessment, i.e., tokenistic presentation of reconnaissance-level species lists without further analysis of
the development implications for individual organisms or communities. None of the assessments reviewed provided statistically
rigorous analysis, which would be required if ecological impact studies are to include quantitative and testable predictions
of impact, which could then be followed up by appropriate post-impact monitoring programs. Attention to key local issues such
as biodiversity or ecosystem services, which also have strong social dimensions in the developing world, was also notably
underrepresented. It was thus concluded that despite the existence of a sound legislative framework in Sri Lanka, the analysis
contained within EISs generally fails to convey meaningful information to the relevant stakeholders and decision makers involved
in protecting ecological interests and promoting sustainable development. The introduction of strategic environmental assessment
(SEA) is considered an important tool to strengthen the institutional capacity of Sri Lankan government to implement current
regulations and, in particular, to combat the cumulative effects of incremental development. 相似文献

Protected areas (PAs) are expected to conserve nature and provide ecosystem services in perpetuity, yet widespread protected area downgrading, downsizing, and degazettement (PADDD) may compromise these objectives. Even iconic protected areas are vulnerable to PADDD, although these PADDD events are often unrecognized. We identified 23 enacted and proposed PADDD events within World Natural Heritage Sites and examined the history, context, and consequences of PADDD events in 4 iconic PAs (Yosemite National Park, Arabian Oryx Sanctuary, Yasuní National Park, and Virunga National Park). Based on insights from published research and international workshops, these 4 cases revealed the diverse pressures brought on by competing interests to develop or exploit natural landscapes and the variety of mechanisms that enables PADDD. Knowledge gaps exist in understanding of the conditions through which development pressures translate to PADDD events and their impacts, partially due to a lack of comprehensive PADDD records. Future research priorities should include comprehensive regional and country-level profiles and analysis of risks, impacts, and contextual factors related to PADDD. Policy options to better govern PADDD include improving tracking and reporting of PADDD events, establishing transparent PADDD policy processes, coordinating among legal frameworks, and mitigating negative impacts of PADDD. To support PADDD research and policy reforms, enhanced human and financial capacities are needed to train local researchers and to host publicly accessible data. As the conservation community considers the achievements of Aichi Target 11 and moves toward new biodiversity targets beyond 2020, researchers, practitioners, and policy makers need to work together to better track, assess, and govern PADDD globally. 相似文献

Mangrove ecosystems in Sri Lanka are increasingly under threat from development projects, especially aquaculture. An economic
assessment is presented for a relatively large (42 ha) shrimp culture development proposed for the Rekawa Lagoon system in
the south of Sri Lanka, which involved an extended cost–benefit analysis of the proposal and an estimate of the “total economic
value” (TEV) of a mangrove ecosystem. The analysis revealed that the internal benefits of developing the shrimp farm are higher
than the internal costs in the ratio of 1.5:1. However, when the wider environmental impacts are more comprehensively evaluated,
the external benefits are much lower than the external costs in a ratio that ranges between 1:6 and 1:11. In areas like Rekawa,
where agriculture and fisheries are widely practiced at subsistence levels, shrimp aquaculture developments have disproportionately
large impacts on traditional livelihoods and social welfare. Thus, although the analysis retains considerable uncertainties,
more explicit costing of the environmental services provided by mangrove ecosystems demonstrates that low intensity, but sustainable,
harvesting has far greater long-term value to local stakeholders and the wider community than large shrimp aquaculture developments. 相似文献

Wildlife trade has rapidly expanded on social media platforms in recent years, offering an easy means for traders to access international markets. Investigating this trade activity poses a complex challenge to researchers seeking to understand online trade and moderators seeking to disrupt illicit and harmful activity. Current survey methods frequently rely on text-based searches and focus on posts in which the advertisement is explicit. However, such approaches risk overlooking a growing volume of relevant content, particularly outside social media groups. We used posts from pages promoting West African birds for trade as a case study to explore the availability of information for making inferences about trade activity on social media, specifically information indicating that trade activity was occurring or that could be used to infer trade routes. We recorded 400 posts from 12 pages that we inferred either promoted or facilitated wildlife trade, of which 19.7% were explicit advertisements and 23.8% contained taxa-related terms. In the remaining 341 posts, profile information was the most common indicator of trade activity, but a variety of indicators (e.g., images of birds in trade and trade enquiries) were identified across imagery, text, and comments. We identified multiple types of geographical information that could help infer trade routes and thus the likely legality of trade, although most were relatively rare and sometimes contradictory. Our findings suggest that triangulating multiple types of information from within, across, and beyond posts is vital for effectively identifying and interpreting wildlife trade content on social media. Therefore, were commend that expert-mediated triangulation should be integrated in and used alongside automated detection systems and moderating practices of social media companies. 相似文献
