Benefits of local structural protection to mitigate torrent-related hazards.

The increasing land-use activities in European mountain regions have led to a considerable threat of natural hazards such as flash floods and debris flows in areas used for settlement purposes and economic activities. To mitigate associated losses, traditional protective measures, including check dams and retention basins, were commonly implemented by public authorities. However, due to the scarceness of public funds, efficient protection alternatives have to be developed to reduce future expenditures.

Möglichkeiten zur Minderung des Hochwasserrisikos durch Nutzung von Flutpoldern an Havel und Oder

With respect to the enormous damages floods have caused in Central Europe in the last few years (Odra 1997, Elbe 2002), the use of detention areas for reducing flood risk is of high importance in modern flood management. By the controlled flooding of sparsely populated areas with low damage potential the risk for downstream areas with higher vulnerability can be reduced. The report presents the results of a research project funded by the German Federal Ministry of Research.

Flood risk reduction by the use of retention areas at the Elbe River

The paper presents research results on flood risk mitigation by the controlled flooding of a retention area on the middle reaches of the Elbe River. The retention area consists of six large polders and the floodplain of a tributary, the Havel, and is located near the Havel's confluence with the Elbe River. The total retention volume of both the polders and the Havel floodplain amounts to approximately 250 million m3. The controlled flooding of the retention area was simulated by the use of a conceptual model and assessed economically for two flood scenarios.

Effectiveness and efficiency of early warning systems for flash-floods (EWASE)

The issue addressed within the EWASE project centres on the assessment of the effectiveness and efficiency of Early Warning Systems (EWS) for medium sized river basins prone to flash floods. The approach pursued relates the concept of risk analysis to the evaluation of strategies for flood damage prevention through early warnings. For the assessment of EWS efficiency, the reliability of forecasts will be linked to the potential damage reduction - both as a function of forecast lead time.

Aportaciones desde la economía de la adaptación a la toma de decisiones sobre Cambio Climático: un ejemplo para la Comunidad Autónoma del País Vasco

As a consequence of Climate Change sea level rise as well as a change in the intensity and propensity of rain are expected in the Basque Country. Valuing the costs and benefits of adapting to these changes becomes an important piece of information for the planning process. This paper develops two methodological frameworks. The first one devoted to estimating the economic impacts to urban areas of an increase in the risk of flooding.

Vulnerability of Bangladesh to Cyclones in a Changing Climate: Potential Damages and Adaptation Cost

This paper integrates information on climate change, hydrodynamic models, and geographic overlays to assess the vulnerability of coastal areas in Bangladesh to larger storm surges and sea-level rise by 2050. The approach identifies polders (diked areas), coastal populations, settlements, infrastructure, and economic activity at risk of inundation, and estimates the cost of damage versus the cost of several adaptation measures.

Optimal crop protection against climate risk in a dynamic cost-loss decision-making model

Extreme meteorological events have increased over the last decade and it is widely accepted that it is due to climate change. Some of these extremes like drought or frost episodes largely affect agricultural outputs that could face a serious decline. Therefore, additional efforts on technology and adaptation become crucial to reduce the effect of climate change on agricultural production.

Adaptation to Climate Extremes in Developing Countries: The Role of Education

Global climate models predict a rise in extreme weather in the next century. To better understand future interactions among adaptation costs, socioeconomic development, and climate change in developing countries, observed losses of life from floods and droughts during 1960–2003 are modeled using three determinants: weather events, income per capita, and female education. The analysis reveals countries with high female education weathered extreme weather events better than countries with equivalent income and weather conditions.

Climate Amenities and Adaptation to Climate Change: A Hedonic-Travel Cost Approach for Europe

We investigate the impact of climatic change on welfare in European regions using a hedonic travel-cost framework and focusing on tourism demand. Our hedonic price estimations combine detailed hotel price information with tourism-specific travel cost estimations for each pair of EU region. This approach allows us to estimate different valuations of climate amenities depending on time duration of holidays. In our analysis of adaptation to climate change we therefore consider holiday duration as variable of adaptation.

Agricultural adaptation to climate change in China.

This paper presents the study on agriculture adaptation to climate change by adopting the assumed land use change strategy to resist the water shortage and to build the capacity to adapt the expected climate change in the northern China. The cost-benefit analysis result shows that assumed land use change from high water consuming rice cultivation to other crops is very effective. Over 7 billions m³ of water can be saved.
