Coping with uncertainty in the inland navigation market: the impact of climate change.

In this paper a model is developed to study an inland waterway market’s production uncertainty due to fluctuating water-levels. Aspects that are studied are climate change and adaptation strategies against climate change. As an example of private adaptation the optimal barge-size, and as an example of public adaptation the optimal amount to investment in infrastructure are derived. We find that the trend to increase barge sizes in the Western European market is theoretically justified.

Adaptation à court et à long terme de l’agriculture au risque de sécheresse : une approche par couplage de modèles biophysiques et économiques.

In this article, we analyse the impact of drought risk on agriculture. We use a biophysical crop growth model (STICS) in order to simulate crop yield under various climatic scenarios. A micro-economic model which optimises, under climate uncertainty, land allocation across crops and irrigation is developed to reflect farmer’s behaviour. This framework is used to assess the impact of drought risk on a representative French farmer located in the Midi-Pyrénées region (South-West of France). We first show that, on the short run, the private cost of a drought can be high.

The implications of climate change for extreme weather events and their socio-economic consequences in Finland.

This publication reports on the main findings the entire TOLERATE project, which was an integrated natural science – social science project for the assessment of climate changed induced changes of extreme weather events and their socialeconomic consequences at a regional level. It includes regional projections of changes in climate conditions in Finland, with special reference to (short) periods with extremely abundant and extreme scant precipitation respectively. Based on these projections changes in river flood risks are assessed for two water shed areas by means of hydrological models.

Weather Vulnerability, Climate Change, and Food Security in Mt. Kilimanjaro.

This study estimates the impact of rainfall variation on livelihood in Mt. Kilimanjaro using the Ricardian approach to capture farmers’ adaptation strategies to cope with climate change risks. The data for the analysis were gathered from a random sample of over 200 households in 15 villages and precipitation from rainfall observation posts placed in each of the surveyed villages. The precipitation data provide information on the effect of moisture at critical months in the growing season.

Optimal location of new forests in a suburban region

This paper looks at the optimal location of new forests in a suburban region under area constraints. The GIS-based methodology takes into account use benefits such as timber, hunting, carbon sequestration and recreation, non-use benefits (both bequest and existence values), opportunity costs of converting agricultural land, as well as planting and management costs of the new forest. The recreation benefits of new forest sites are estimated using function transfer techniques.

Wetland valuation : state of the art and opportunities for further development.

Valuing the environment remains a problematic and controversial process. Objections vary from concerns about the legitimacy of the procedure to the technical difficulty of the process itself. The purpose of this workshop was to explore these concerns in the context of managed realignment. The purpose of the workshop was real moreover and not dryly academic. Like it or not, a quantified case goes along way in the today’s policy climate. Thus the environment is at a great disadvantage, if soundly based numbers cannot be deployed in its defence.

Economic Evaluation of Climate Change Impacts and Adaptation in Italy

The paper deals with the social and economic dimensions of climate change impacts and adaptation in Italy. The ultimate aim of the paper is to provide policy makers and experts with a conceptual framework, as well as methodological and operational tools for dealing with climate change impacts and adaptation from an economic perspective. In order to do so, first a conceptual and theoretical framework of the economic assessment of climate change impacts is presented and the state of the art about impact assessment studies is briefly analysed.

A Hurricane’s Long-Term Economic Impact: the Case of Hawaii’s Iniki

The importance of understanding the macro-economic impact of natural disasters cannot be overstated. Hurricane Iniki, that hit the Hawaiian island of Kauai on September 11th, 1992, offers an ideal case study to better understand the long-term economic impacts of a major disaster. Iniki is uniquely suited to provide insights into the long-term economic impacts of disaster because (1) there is now seventeen years of detailed post-disaster economic data and (2) a nearby island, Maui, provides an ideal control group.

A participatory approach for assessing alternative climate change adaptation responses to cope with flooding risk in the upper Brahmaputra and Danube river basins

This work illustrates the preliminary findings of a participatory research process aimed at identifying responses for sustainable water management in a climate change perspective, in two river basins in Europe and Asia. The paper describes the methodology implemented through local workshops, aimed at eliciting and evaluating possible responses to flooding risk. Participatory workshops allowed for the identification of four categories of possible responses and a set of nine evaluation criteria, three for each of the three pillars of sustainable development.

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.
