Using Ecological Footprints as a Policy Driver: The Case of Sustainable Construction Planning Policy in London

The heuristic value of the ecological footprint (EF) conceptual device has met with considerable political and civic buy-in at national, regional and local levels. It is seen as particularly valuable for visualizing ecological overshoot but debates about methodological soundness have undermined this potential. This paper examines the emerging opportunities for advanced footprinting approaches that use input-output analysis to test 'what if?' policy scenarios and hence turn EF into a proactive driver for sustainability-oriented policy development. It focuses on the London case and the specific arena of planning policy for sustainable construction.     

Using Ecological Footprints as a Policy Driver: The Case of Sustainable Construction Planning Policy in London

Abstract

The forests of Nepal, which in the past were at least nominally under the direct control of the state, are today increasingly entrusted to local people in the name of community forestry (CF). CF is considered a successful endeavour in managing forest resources, conserving biodiversity and supplying people with basic economic needs. In order to assess to what extent the two goals of biodiversity conservation and meeting economic needs of people have been integrated through CF, four community forestry user groups (CFUGs) were studied in the Mid-hills ecological zone. Based on a participatory survey and a critical review of the statutes and operational plans of these CFUGs, it was found that integration of biodiversity conservation was still insufficient, and that improvements in the policy and management regimes of CF are necessary to achieve a balance between biodiversity conservation and economic use of the forest resources.     

城市生态休闲绿地建设研究

城市生态休闲绿地不同于城市绿地,主要包括其中的城市公园绿地和其他绿地。结合市民平时主要在居住地附近散步、节假日喜欢到郊区游憩的休闲活动特点,把生态休闲绿地分为日常短时休闲绿地和节假日长时休闲绿地。在城市生态休闲绿地建设中,应重点建设日常短时休闲绿地,配套开发节假日长时休闲绿地,完善城市公共绿地的休闲设施,增强城市公共绿地的大众性,提高专有绿地的开放性。

Bovine Tuberculosis and Badger Control in Britain: Science,Policy and Politics

Bovine tuberculosis (bovine TB) is the most economically important animal health policy issue in Britain. The problem of what to do about badgers has plagued successive governments since a dead badger was discovered with bovine TB in 1971. Successive Labour governments (1997–2010) oversaw the Randomised Badger Culling Trial (RBCT) from 1998 to 2006. Despite the RBCT recommendation against culling, the 2010–2015 Coalition government implemented pilot badger culls. This paper provides an account of the evolution of bovine TB and badger control policy, focusing on the 1997–2010 Labour, the 2010–2015 Coalition and the 2015-present Conservative governments. Interviews with bovine TB policy stakeholders supplement discussion of the development of bovine TB policy. The paper discusses the science and politics of bovine TB policy, in which there are different badger control policies in Westminster, Welsh and Scottish governments. Badger control is a highly polarised issue, and the Coalition and Conservative governments have been heavily criticised for a culling policy opposed by the independent scientific community. Recent governments have defended badger culling on the basis of veterinary advice and experience in countries such as New Zealand. The paper concludes with two key recommendations to inform controversial animal health and welfare policy issues such as bovine TB. First, mandatory Animal Welfare Impact Assessment provides objective data on the impacts of policy options on cows and badgers. Second, robust ethical analysis, conducted by independent experts using established moral frameworks, should be applied to animal health and welfare issues for the benefit of decision makers.     

Science, Policy, and Stakeholders: Developing a Consensus Science Plan for Amchitka Island, Aleutians, Alaska

With the ending of the Cold War, the US Department of Energy is responsible for the remediation of radioactive waste and disposal of land no longer needed for nuclear material production or related national security missions. The task of characterizing the hazards and risks from radionuclides is necessary for assuring the protection of health of humans and the environment. This is a particularly daunting task for those sites that had underground testing of nuclear weapons, where the radioactive contamination is currently inaccessible. Herein we report on the development of a Science Plan to characterize the physical and biological marine environment around Amchitka Island in the Aleutian chain of Alaska, where three underground nuclear tests were conducted (1965–1971). Information on the ecology, geology, and current radionuclide levels in biota, water, and sediment is necessary for evaluating possible current contamination and to serve as a baseline for developing a plan to ensure human and ecosystem health in perpetuity. Other information required includes identifying the location of the salt water/fresh water interface where migration to the ocean might occur in the future and determining groundwater recharge balances, as well as assessing other physical/geological features of Amchitka near the test sites. The Science Plan is needed to address the confusing and conflicting information available to the public about radionuclide risks from underground nuclear blasts in the late 1960s and early 1970s, as well as the potential for volcanic or seismic activity to disrupt shot cavities or accelerate migration of radionuclides into the sea. Developing a Science Plan involved agreement among regulators and other stakeholders, assignment of the task to the Consortium for Risk Evaluation with Stakeholder Participation, and development of a consensus Science Plan that dealt with contentious scientific issues. Involvement of the regulators (State of Alaska), resource trustees (U S Fish and Wildlife Service), representatives of the Aleut and Pribilof Island communities, and other stakeholders was essential for plan development and approval, although this created tensions because of the different objectives of each group. The complicated process of developing a Science Plan involved iterations and interactions with multiple agencies and organizations, scientists in several disciplines, regulators, and the participation of Aleut people in their home communities, as well as the general public. The importance of including all parties in all phases of the development of the Science Plan was critical to its acceptance by a broad range of regulators, agencies, resource trustees, Aleutian/Pribilof communities, and other stakeholders.     

Water-sensitive Urban Planning: Protecting Groundwater

Sustainable development requires the promulgation of guidelines for urban planning which consider the effects of the built environment on water resources. In this context, our paper focuses on the effects of urban development on the quantity and quality of rainwater which infiltrates into the soil on its way to recharge the aquifer. The paper includes: identification of the state of knowledge regarding the effect of urban development on runoff and infiltration; a case study-estimation of the effect of certain patterns of urban development in an Israeli neighbourhood,together with an option for mitigating them by relatively simple and inexpensive means; presentation of the components of urban planning which influence runoff and infiltration; and proposals for continuing research in this area which has been relatively neglected until recently.     

Translating Science into Coastal Development Decisions: The Articulations Science and Planning in South Australia

Climate change risks to the coast and coastal developments have been well-documented. In spite of these warnings, new coastal developments are still proposed and built. Australian research has demonstrated how State-level planning documents fail to incorporate recent sea-level rise projections, with researchers demanding more responsiveness to coastal science from planners, policy-makers and developers. This paper takes an alternative approach to the science, planning and coastal development nexus by developing a relational understanding of the barriers to the uptake of science into coastal development decisions. Drawing on qualitative interview material from two recent and non-routine South Australian cases where sea-level rise (SLR) science was contested, and inspiration from actor-network theory's concepts of obligatory passage points, translation, intermediaries and mediators, this research foregrounds the malleability of scientific knowledge and planning protocols. We find that skilful social actors negotiate and re-frame science and planning; clear scientific recommendations can be subsumed to planning process, while clear planning process creates internecine disputes between nomothetic and idiographic science. An implication of this analysis is that the broad narrative of a lack of scientific uptake into coastal development needs to be sensitized to how science and planning interact in practice to legitimate decisions.

Ecological Compensation in Dutch Highway Planning

The ecological compensation principle was introduced by the Dutch government in 1993. This principle is designed to enhance the input of nature conservation interests in decision-making on large-scale development projects and to counterbalance the ecological impacts of such developments when implemented. This article evaluates the application of the Dutch compensation principle in highway planning. Six current highway projects reveal consistent implementation of this principle, although provincial policies on compensation and a national method for identifying compensation measures are still under development. As the planning process has not yet been completed for all the projects, no general conclusions can be drawn on the impact of the compensation principle on highway decision-making. Nevertheless, several examples show that the principle stimulates project initiators to develop alternative routes or route sections in order to avoid or reduce ecological impacts and the need for coherent compensation measures. If the compensation principle is to be properly implemented in the context of highway planning, particular attention should be paid to the following aspects: (1) sequential assessment of overall project legitimacy and the necessity of intersecting protected areas and compensation measures, (2) the initiator's attempts to avoid and mitigate ecological impacts in developing alternative routes prior to compensation for impacts, and (3) the role of uncertain ecological impacts in identifying compensation measures, especially those concerning habitat isolation.

Environmental Monitoring in Urban Areas: Political Contexts and Policy Problems

Environmental monitoring activities are examined from a perspective which focuses on the political, economic and social factors which shape what we know and do not know about local environments. A UK urban case study is used to examine the range of influences that can operate on local level monitoring and comparisons are then made with the situation in three other European cities. Conclusions are drawn which debate the appropriate balance between local discretion and national and international direction in the collection of environmental information. It is argued that scrutiny of and revisions to the quality of current environmental monitoring in the UK and wider debate over questions of purpose, scope and resource commitment are needed.
