Urban heat indicator map for climate adaptation planning

By 2050, 75 % of the world’s population will live in cities and the occurrence of heat wave events might have doubled. Mapping the climate and land use change impact for urban heat events should set the agenda for adaptation planning at the local scale. Literature on urban heat mapping does not reveal a clear indicator to visualise the urban heat impacts that includes consequences of land use and climate changes for planning purposes. This paper introduces a stepwise approach to develop a single complex indicator to map the urban heat impact for local climate adaptation planning processes. Information on climatic drivers and land use characteristics are combined and projected for future land use and climate change impacts. Next, several visualisation techniques are developed to investigate which techniques are most effective to visualise complex information with multiple variables in one visualisation. A usability test is performed to investigate how indicator and map meet the information and communication needs of policy makers. Our findings reveal that it is important to add information on future impacts to set the agenda for adaptation planning at the local scale. Applying cartographic techniques in a map series presentation has proven to be effective to map complex information in a single image and fulfil most of the identified information needs. Based on our finding, we introduce the information enrichment chain as a promising approach to support local adaptation planning.     

Industrial transformation towards sustainability of the energy system

Human induced climate change is one of the single most significant indicators that human society is not pursuing a sustainable trajectory. Managing the risks requires a major transformation of the way energy needs are met. Such a transformation includes changes in the production and consumption system and the incentive structure that shapes this system. The major driving force for transformation is the public concern about the environmental impact of the present fossil fuel based energy system. We may expect that energy producers, encouraged by governments, NGOs and consumer preferences will be responding to these concerns and expectations sooner or later. In fact a number of major international energy companies are presently adjusting their strategies to the needs and concerns of the public. A mix of measures including energy efficiency, a switch to natural gas, major investments in low carbon and renewable energy technologies and underground storage of carbon are elements of such new strategies. Consumers in a number of OECD countries have expressed their willingness to pay more for energy, provided it is green and clean. NGOs continue to put pressure on governments to deal with the climate problem. The challenge for governments is to develop an institutional framework that helps the producers and consumers to go through a transformation of the energy system. As different groups in society are likely to support different strategies, this paper suggests that a pluralistic policy approach including efficiency standards, renewable energy portfolio standards, carbon taxes, and the introduction of a system of tradable emission permits is the most promising approach for a transformation towards a low carbon energy economy. Research can support a transformation of the energy system by exploring the various transformation scenarios. Such research should take a multi-disciplinary approach, it should focus on the energy system as a whole, including production, consumption and the incentive structure that shapes the interaction between the two and it should be international in scope.

Sustainable management of transboundary river basins: a line of reasoning

This paper identifies a line of reasoning based on a number of concepts and tools to facilitate river basin management, which have been applied in a case study. For long-term sustainable river basin management, a balance is needed between the human use of the river and its basin, the ecological functioning of the river and receiving waters, and the river's capacity to supply goods and services. To find such a balance a framework is needed that illustrates and clarifies possible trade-offs between economic use and environmental supply by integrating scientific information on cause–effect chains on a catchment scale. A number of concepts and tools are proposed as a basis for this framework. The tools are: (1) indicators that describe the complex interactions and processes in rivers; (2) a suite of linked models that predict the economic, environmental and ecological effect of management measures; (3) an evaluation framework to rank different management alternatives on the basis of three objectives: economic efficiency, spatial equity in costs and benefits and environmental quality of the river and receiving lakes. The concept of environmental quality defines the potential of the river environment (i.e. natural capital) to contribute to human welfare. The concept of environmental functions is used to identify societal interest in natural capital. The concept and tools have been applied in a case study involving the evaluation of four management strategies on nutrient abatement in the Rhine basin. The result of the case study is that economic efficiency is in conflict with spatial equity and environmental quality. Spatial equity is in agreement with environmental quality.

The European Forum on Integrated Environmental Assessment

Integrated Environmental Assessment (IEA) can be loosely defined as policy‐relevant, multidisciplinary research on environmental issues. Many, diverse activities in this broad field are ongoing, but the approaches lack the structure, standardization and quality control common in disciplinary research. IEA has three stages: “structuring the problem”, “analyzing the problem” and “communicating the findings and insights”. Each stage has its inherent difficulties, not least because problem definition and analysis are neither separable nor unambiguous nor unique. Difficulties are exacerbated in the first and third stages by the necessity for science and policy to work together. Difficulties are exacerbated in the second stage by the necessity of different scientific disciplines to cooperate. The European Forum on Integrated Environmental Assessment is an initiative to improve scientific quality and policy‐relevance of IEA, by organizing two series of workshops, one looking in detail at current and desired scientific practices, the other reviewing current and establishing further applications of IEA to environmental issues in Europe.

Climate Science and Climate Policy: Improving the Science/Policy Interface

The development of an international climate policy builds on national policy perspectives. These depend on the perceived risks of climate change, socioeconomic and cultural characteristics of the nations and regions involved, and the technical feasibility of policy measures. Scientific and technological research supports the policy making process about these issues. The perspectives of the scientific community and the policy makers differ and as a consequence communication is often troublesome. The construction and utilization of knowledge under such circumstances can only be effective if all parties involved engage in a continuous dialogue about causes, effects, impacts and responses. This paper describes a project carried out in the Netherlands. It has as its major objective the articulation of a variety of perceptions and positions related to climate change. As a result of the project, policy actors produced five policy options and formulated research questions. The policy options are linked in the framework of a policy life cycle. Research questions focus on the risks of climate change and on feasible social, economic, cultural and technological responses to it. As to the policy options, striving for common means appears to be more promising than pursuing shared goals and philosophies.     

Experiences with restoration of inland freshwater wetlands in the Netherlands: lessons for science and policy-making

The past decade has seen important changes in the approach to water management issues in the Netherlands. Urban development, recreational demands, agriculture, nature conservation and other space demanding functions compete with water management objectives in their claims for space. An analysis of some recent water management projects illustrates that the implementation of the new water management approach is not always easy. Catchment-based multifunctional projects encounter major constraints. These constraints are: 1) national goals versus local constraints; 2) limited sense of urgency; 3) lack of institutional coordination in the water management community; 4) unclear views over nature conservation, and; 5) limited understanding of wetland functioning in relation to flood risk management. We promote platforms for collaborative planning as a way to improve stakeholder participation in early stages of decision-making. Negotiation and mediation support tools can enable stakeholders and mediators to formulate the problems that need to be addressed more effectively. Early involvement of stakeholders in the planning process is almost a condition for successful implementation; however, it is no guarantee of success, and not all conflicts can be solved. Therefore assessment of the costs and benefits of different parties is important for compensation schemes to gain broad social acceptance.
