Cost-benefit analysis in climate change adaptation: the use of participatory methodologies

Cost-benefit analysis, as an economic evaluation tool of public or private projects, has evolved significantly in the last 200 years following the developments in terms of economics, namely Environmental Economic, and developments in project analysis and public policy evaluation.

Adaptation to sea level rise: Calculating costs and benefits for the case study Kalundborg, Denmark

Rising sea levels are expected to cause an increased risk of coastal flooding in many regions and adaptation to these threats is necessary to avoid considerable losses. Yet, such measures will typically only be implemented if they are economically efficient, that is, if the benefits in terms of avoided damages exceed the implementation costs. By employing extreme value theory we perform a cost-benefit analysis for a specific protection measure in a case study region in Kalundborg (Denmark) and calculate the amortisation times for several sea level scenarios and discount rates.

Adaptation to extreme rainfall with open drainage system: An integrated hydrological cost-benefit analysis.

This paper presents a cross-disciplinary framework for assessment of climate change adaptation to increased precipitation extremes considering pluvial flood risk as well as additional environmental services provided by some of the adaptation options. The ability of adaptation alternatives to cope with extreme rainfalls is evaluated using a quantitative flood risk approach based on urban inundation modeling and socio-economic analysis of corresponding costs and benefits. A hedonic valuation model is applied to capture the local economic gains or losses from more water bodies in green areas.

Effectiveness of flood damage mitigation measures: Empirical evidence from French flood disasters

Recent destructive flood events and projected increases in flood risks as a result of climate change in many regions around the world demonstrate the importance of improving flood risk management. Flood-proofing of buildings is often advocated as an effective strategy for limiting damage caused by floods. However, few empirical studies have estimated the damage that can be avoided by implementing such flood damage mitigation measures.

Adaptation in the UK: a decision-making process

This report contributes to the theoretical framework of the Committee on Climate Change Adaptation Sub-Committee’s work on assessing the preparedness of the UK to meet the risks and opportunities arising from climate change.

Ranking sources of uncertain-ty in flood damage modelling: a case study on the cost-benefit analysis of a flood mitigation project in the Orb Delta, France.

Cost-benefit analyses (CBA) of flood management plans usually require estimating expected annual flood damages on a study area, and rely on a complex modelling chain including hydrological, hydraulic and economic modelling as well as GIS-based spatial analysis. As most model-based assessments, these CBA are fraught with uncertainty. In this paper, we consider as a case-study the CBA of a set of flood-control structural measures on the Orb Delta, France.
