The linkages between disaster and environmental damage are recognized as important to predicting, preventing and mitigating the impact of disasters. Environmental Impact Assessment (EIA) procedures are well developed for non-ndisaster situations. However, they are conceptually and operationally inappropriate for use in disaster conditions, particularly in the first 120 days after the disaster has begun. The paper provides a conceptual overview of the requirements for an environmental impact assessment procedure appropriate for disaster conditions. These requirements are captured in guidelines for a Rapid Environmental Impact Assessment (REA) for use in disasters. The REA guides the collection and assessment of a wide range of factors which can indicate: (1) the negative impacts of a disaster on the environment, (2) the impacts of environmental conditions on the magnitude of a disaster and, (3) the positive or negative impacts of relief efforts on environmental conditions. The REA also provides a foundation for recovery program EIAs, thus improving the overall post disaster recovery process. The REA is designed primarily for relief cadres, but is also expected to be usable as an assessment tool with disaster victims. The paper discusses the field testing of the REA under actual disaster conditions.

The challenge for implementing an ecosystems approach to environmental decision-making processes, such as spatial planning, is to understand the range, nature and amount of ecosystem services currently provided and the potential for such service provision in the future. The ability to spatially represent ecosystems services is a critical element of the evidence base on which to make decisions about how physical space is used most effectively and sustainably, and the way people and activities are distributed at different spatial scales. This paper reports on the outcomes of a research project originally undertaken for the UK Department for the Environment, Food and Rural Affairs which developed a methodology for mapping ecosystem services using GIS and readily available, existing land use/land cover datasets. Critical components of the methodology, in order to determine which datasets are appropriate for which services, are network analysis and stakeholder engagement techniques, to define the relevant typology of ecosystem services and their relationship to land use/land cover types. The methodology was developed and tested successfully in the context of green grid (green infrastructure) networks in a major UK regeneration area, the Thames Gateway, to the east of London, and its potential use in impact assessment further explored through a number of case studies.

One of the requirements for a good Strategic Environmental Assessment (SEA) is its capacity to adjust itself to the planned decision-making process. This paper presents recent experiences involving the application of SEA in Brazil in three different contexts. In the first case, an SEA was conducted to meet a request of the Ministry of Tourism for information to prepare the Development Plan for Sustainable Tourism in the North Coast. The second case is an initiative undertaken by the Secretary of Environment of the State of Bahia for the construction of a seaport-industrial complex in the region of Ilhéus (Bahia). Finally, an SEA commissioned by a group of environmental NGOs to assess options for the development of a mining-metal and chemical-gas complex in the Pantanal Region near the Bolivian and Paraguayan border is presented. The paper highlights the differences in the contexts of the three studies (responsibilities in the decision-making process, stages of the planning process, etc.) as well as in their methodological approaches. Difficulties, gaps, advances and findings in each case are also analysed to assess the effectiveness of each SEA.

Environmental Risk Assessment (ERA) is a powerful set of technical and analytical instruments for analyzing environmental impacts, and has found application in supporting Decision-Making Processes (DMPs) over the last two decades. However, there is no interrelated application of ERA in Strategic Decision-Making (SDM) processes, and no systematic research on the approaches and methods of ERA to support the processes of SDM. In this paper, a new approach and methodological system of ERA for SDM process is set up, and then applied to the Principal Coastal Functional Zoning (PCFZ) in Xiamen Bay, China, as a case study to verify the feasibility of the proposed approach and its methodology. The results show that the approach and methodology of ERA for SDM could integrate ERA into the entire SDM process, and thereby support the PCFZ directly. Furthermore, this approach avoids or mitigates against dire environmental risk that are sometimes introduced by the SDM processes.
