Does phosphate treatment for prevention of eutrophication pass the benefit-cost test?

Over the past few decades the problem of eutrophication of water bodies has accelerated due to large additions of nutrients from human sources. This paper conducts a contingent valuation of household willingness to pay to reduce eutrophication impacts. The application employs the recently proposed one-and-one-half-bound dichotomous choice method for eliciting willingness to pay responses. It is also novel in that an examination of the rate and determinants of survey participation are analysed allowing superior aggregation of total values by allowing for those who refuse to be interviewed.

Scenarios and Sustainability - A Swedish Case Study of Adaptation Tools for Local Decision-Makers

Adaptation to climate change often involves long time frames and uncertainties over consequences of chosen adaptation measures. In this study, two tools developed for assisting local decision-makers in adaptation planning were tested: socio-economic scenarios and sustainability analysis. The objective was to study whether these tools could be of practical relevance to Swedish municipalities and foster local level climate change adaptation.

Adaptation measures in the EU : policies, costs, and economic assessment : climate proofing of key EU policies

The aim of this report was to identify the most appropriate measures on the EU level to address different threats. A final selection of measures to be assessed with a view to their costs and economic, social and environmental impacts was agreed at the first interim meeting with the Commission. Measures already part of EU wide assessment projects were no part of the assessment.

Nonuse values of climate policy : an empirical study in Xinjiang and Beijing

In this study we test empirically the hypothesis that also in a growth-oriented economy like China non-materialistic values like the nonuse values of climate policy are perceived and respected by the population. This should especially hold for the better educated people living in big cities like Beijing. Therefore, we conduct a survey in Beijing where we ask people to assess a climate change adaptation project to be implemented in a faraway region, in this case in the Tarim basin in Xinjiang.

Estimating the value of economic benefits associated with adaptation to climate change in a developing country: A case study of improvements in tropical cyclone warning services

Linking tropical cyclone activity with anthropogenic climate change is subject to on-going debate. However, modelling studies consistently have projected that climate change is likely to increase the intensity of cyclones and the related rainfall rates in the future. A precautionary approach to this possibility is to adapt to the adverse effects of the changing climate by improving early warning services for cyclones as a ‘no or low-regrets’ option. Given limited funding resources, assessments of economic efficiency will be necessary, and values for benefits are an essential input.

Economics of Climate Change in East Asia

This study addresses the economics of climate change in selected countries in the East Asian region, focusing on the People’s Republic of China, Japan, the Republic of Korea, and Mongolia. It explores the economics of climate change adaptation at a subnational scale (i.e., provinces or regions), incorporates more climate scenarios, and examines climate uncertainty in more depth than previous work. Moreover, this study explicitly combines the costs of adaptation and mitigation into a single framework, while exploring linkages with the global economy.

Compendium on methods and tools to evaluate impacts of, and vulnerability and adaptation to, climate change

In 1999, the UNFCCC Secretariat took a first step towards disseminating information on methods and tools when it produced a report entitled Compendium of Decision Tools to Evaluate Strategies for Adaptation to Climate Change. Since then, the adaptation assessment process has changed considerably and in some ways grown more sophisticated. The UNFCCC Secretariat has subsequently updated the original compendium and broadened its scope.

Discounting the distant future: how much do uncertain rates increase valuations?

We demonstrate that when the future path of the discount rate is uncertain and highly correlated, the distant future should be discounted at significantly lower rates than suggested by the current rate. We then use two centuries of US interest rate data to quantify this effect. Using both random walk and meanreverting models, we compute the ‘‘certainty-equivalent rate’’ that summarizes the effect of uncertainty and measures the appropriate forward rate of discount in the future.

MEDIATION and the Adaptation Challenge: Identifying appropriate methods and tools to support climate change adaptation decision making.

The MEDIATION project guides researchers, policy advisors and experts to suitable climate change adaptation methods and tools for a wide range of questions and from various disciplines and perspectives. The project involves 11 partners and 11 case studies. Summaries of five of these case studies can be found in the present publication. Further information on the MEDIATION methodology, Adaptation Platform and training materials, which were developed for experts with basic technical or scientific knowledge rather than the general public,
