Evaluation of environmental feasibility of steel pipe sheet pile cutoff wall at coastal landfill sites

An evaluation method that can express the local leakage of leachate from joint sections in steel pipe sheet pile (SPSP) cutoff walls is discussed in this study. In particular, the evaluation of environmental feasibility (containment of leachates containing toxic substances) considering a three-dimensional arrangement and hydraulic conductivity distribution of the joint sections in the SPSP cutoff wall is compared with an evaluation that uses the equivalent hydraulic conductivity. This equivalent hydraulic conductivity assumes that the joint section and the steel pipe are integrated; therefore, the hydraulic conductivity is substituted with a uniform permeable layer. However, in an evaluation that employs the equivalent hydraulic conductivity, it is difficult to consider the local leakage of leachate containing toxic substances from the joint sections in the SPSP cutoff wall. It was established that evaluations of the environmental feasibility of SPSP cutoff walls with joint sections must take into account the local leakage of leachates containing toxic substances from the joint sections. Also, it was clarified that technologies that lower the hydraulic conductivities of joint sections in SPSP cutoff walls and also facilitate the use of sparser joint arrangements contribute significantly to increasing the environmental feasibility of SPSP cutoff walls at landfill sites.     

Understanding local community attitudes toward industrial development in the Great Barrier Reef region World Heritage Area: are environmental impacts perceived to overshadow economic benefits?

Conflicts between industrial development and environmental conservation can be particularly acute when such development occurs in the vicinity of World Heritage sites. A key example is the Great Barrier Reef World Heritage Area (GBRWHA) in northeastern Australia, where a 2012 review by the World Heritage Council found that rapid port development inshore of the coral reef posed significant risks to local marine ecosystems. Such instances pose pressing challenges for decision‐makers seeking to manage World Heritage sites for multiple values and needs, including those of key stakeholder groups, such as local communities. There is increasingly a societal expectation that public decision‐making takes into account local views and priorities, and that companies seek a ‘social license to operate’. This research explored local community attitudes toward port development associated with the export of liquefied natural gas (LNG) and coal through the GBRWHA. Using data drawn from a survey and interviews, the research examined how a range of geographical factors, including proximity to gas infrastructure and the perceived impacts and risks of development to the local community, economy and environment shape community perceptions of the industry. Findings suggest that local attitudes toward gas and coal terminal development inshore of the GBRWHA are shaped predominantly by community perceptions of environmental impacts and risks associated with such infrastructure, in contrast to a broader public narrative that focuses largely on economic benefits. A complex combination of other factors, including social impacts, personal environmental values, community trust in industry, and equity in decision‐making and distribution of the risks and benefits of industrial development also contribute. Placed in a broader, global context, the findings have important implications for public decision‐making processes in Australia and elsewhere as they suggest that, for local communities, the perceived impacts of gas development on the environment may overshadow the benefits of industry.     

The Tea Party versus Agenda 21: local groups and sustainability policies in U.S. cities

As local governments have moved toward adopting sustainability policies, there have been some cases where local Tea Parties have emerged as aggressive and strident opponents of such changes. Looking broadly at the Tea Party movement across the United States and systematically measuring its influence in urban America, we assess each Tea Party chapter’s capacity – its ability to convert resources into meaningful political advocacy. Data is derived from surveys of political elites in 50 cities as well as from determining the level of sustainability programming in each of these same cities. Evidence demonstrates that the Tea Party has not had a significant impact on city policymaking in the area of sustainability. Rather, the typical Tea Party chapter appears to be at best a modest presence in local politics.     

Local government,political decentralisation and resilience to natural hazard-associated disasters

Natural hazards affect development and can cause significant and long-term suffering for those affected. Research has shown that sustained long-term disaster preparedness combined with appropriate response and recovery are needed to deliver effective risk reductions. However, as the newly agreed Sendai framework recognises, this knowledge has not been translated into action. This research aims to contribute to our understanding of how to deliver longer term and sustained risk reduction by evaluating the role of political decentralisation in disaster outcomes. Specifically, we investigate whether countries which devolve power to the local level experience reduced numbers of people affected by storms and earthquakes, and have lower economic damage. Using regression analysis and cross-country data from 1950 to 2006, we find that, in relation to both storms and earthquakes, greater transfers of political power to subnational tiers of government reduce hazard impacts on the population. The downside is that more politically decentralised countries, which are usually wealthier countries, can increase the direct economic losses associated with a natural hazard impact after the storm or earthquake than those which are more centralised. However, overall, it seems advantageous to give subnational governments more authority and autonomy in storm and earthquake risk planning.     

Chinese construction companies in Angola: A local linkages perspective

China tends to spearhead its economic overtures to African countries through high-level bilateral negotiations. These are frequently in the form of China Exim Bank loans for large-scale infrastructure projects, repaid by resource exports to China. While much is made of China's resource-based activities in Africa, less focus is placed on the converse of this relationship—the infrastructure provision that African resources buy from China. This article takes the positions that local linkages development is one of the clearest ways that African countries can benefit from Chinese construction companies' market engagement. The prevailing view is that Chinese companies contracted to undertake the construction projects financed in this way do not use local labour, materials or any other inputs in the undertaking of their contracts. Focusing on the strategic orientation of large Chinese companies state-owned enterprises (SOEs) operating in Angola's construction sector, this article seeks to uncover the determinants of their sourcing behaviour, and the manner in which this is reflected in their use of local inputs.     

Multi-step approach for comparing the local air pollution contributions of conventional and innovative MSW thermo-chemical treatments

In the sector of municipal solid waste management the debate on the performances of conventional and novel thermo-chemical technologies is still relevant. When a plant must be constructed, decision makers often select a technology prior to analyzing the local environmental impact of the available options, as this type of study is generally developed when the design of the plant has been carried out. Additionally, in the literature there is a lack of comparative analyses of the contributions to local air pollution from different technologies. The present study offers a multi-step approach, based on pollutant emission factors and atmospheric dilution coefficients, for a local comparative analysis. With this approach it is possible to check if some assumptions related to the advantages of the novel thermochemical technologies, in terms of local direct impact on air quality, can be applied to municipal solid waste treatment. The selected processes concern combustion, gasification and pyrolysis, alone or in combination. The pollutants considered are both carcinogenic and non-carcinogenic. A case study is presented concerning the location of a plant in an alpine region and its contribution to the local air pollution. Results show that differences among technologies are less than expected. Performances of each technology are discussed in details.     

Building the role of local government authorities towards the achievement of the human right to water in rural Tanzania

In recent decades, many changes have occurred in the approach to financing and operating water services in developing countries. The demand‐responsive approach is now adopted in many countries in a context of donor‐supported decentralization processes, which gives more responsibility to end users. However, the government's responsibility at different levels is enforced by the international recognition of the human right to water. This paper examines specific actions that build the role of local government authorities in this scenario. A collaboration between an international NGO and a rural district in Tanzania from 2006 to 2009 is used as an action research case study that is representative of local capacity‐building needs in decentralized contexts and rural areas. Three main challenges were detected: i) lack of reliable information; ii) poor allocation of resources in terms of equity; and iii) lack of long‐term community management support from the district. Two mechanisms were established: i) water point mapping as a tool for information and planning; and ii) a District Water and Sanitation Unit Support (DWUS) for community management. The results show how the framework provided by the goal of human right to water helps to define useful strategies for equity‐oriented planning and post‐project support at the local level.

Nature conservation and local plans

It is noted that nature conservation has gained progressively in importance as a planning issue. The paper reports on the role of the Nature Conservancy Council, and in particular their Assistant Regional Officers, in consulting over the production of local plans. Local plan policies may assist valuably in the protection of important sites, although sympathetic planning authorities can also assist nature conservation in a variety of other ways. Sustained and systematic liaison with planning authorities is necessary for nature conservation to become a substantive local plan issue.     

Enterprise boards: evolution and critique

There has been a marked proliferation of local economic development initiatives in recent years. Enterprise Boards have proved one of the most successful of these innovations. In the early 1980s five were established. Two, the Greater London and the West Midlands Enterprise Boards, were initially designed to intervene radically within their local economies, although subsequent events moderated their activities. The remaining three in Lancashire, West Yorkshire and Merseyside, have successfully widened their operations to embrace collaborate projects with the private sector, training, boosting co‐operatives, and research. By many economic evaluations, for example, jobs supported, leverage ratios and investment per job, Enterprise Boards have performed better than other instruments of urban and regional development. Wider socio‐political objectives have proved more difficult to achieve.
