Purpose – The purpose of this paper is to examine a new insurance policy against natural disasters. Design/methodology/approach – The authors propose an optimisation model, which involves both the insurer and the farmer. The farmer decides to insure his farm if and only if insurance improves...

High losses generated by natural catastrophes reduce the availability of insurance. Among the ways to manage risk, the subscriptions of participating and non-participating contracts respectively permit to implement the two major principles in risk allocation: the mutuality and the transfer...

In Europe, economic evaluation of flood management projects is becoming a commonly used decision tool. At the same time, flood management policies shift towards new concepts such as giving more room to water by restoring floodplain and living with floods. Agricultural areas are particularly...

This paper analyzes the dynamic interaction between two regions with interconnected river basins. Precipitation is higher in one river-basin while water productivity is higher in the other. Water transfer increases productivity in the recipient basin, but may cause environmental damage in the...

Cooperation can increase the efficiency of commonly-owned renewable resource use. However, received knowledge is that, absent side payments, cooperative solutions are more difficult to achieve the less homogenous the agents involved. We revisit this claim by analyzing how differences in the...

In this paper, we focus on resource conservation in a model of decentralized management of groundwater and rainwater. We show that a conservation policy may have opposite effects on the level of the resource, depending on the outcome of the decentralized management. More precisely, we consider...

Cet article passe en revue différentes méthodes pour mesurer la biodiversité et propose d’expliciter leurs fondements axiomatiques. Il offre ensuite un aperçu des concepts développés pour sa protection et il s’achève sur une discussion de quelques spécificités du problème, comme la...

This paper analyzes the dynamic interaction between two regions with interconnected river basins. Precipitation is higher in one river- basin while water productivity is higher in the other. Water transfer increases productivity in the recipient basin, but may cause environmental damage in the...

We consider a problem of groundwater management in which a group of farmers over- exploits a groundwater stock and causes excessive pollution. A Water Agency wishes to regulate the farmer's activity, in order to reach a minimum quantity and quality level but it is subject to a budget constraint...
