Our expertise focuses on the economic models to promote for sustainable development.


In order to go beyond traditional development indicators such as GDP, the IREEDD teams, in collaboration with researchers from Montpellier, have developed a social health indicator for the territories of the Massif Central.

One of the criticisms levelled at this same indicator (GDP) is the lack of links between economic development and the consumption of natural resources. For the Martinique Water Office, we are conceptualising and building a hydro-economic model to establish a link between the economic growth of the territory and the consumption of water resources.

Public services are real instruments of redistribution. To support public institutions and to make debates more objective, we carry out public policy evaluations using economic tools and methods that are recognised and scientifically validated.

As an illustration :


Economic Evaluation of Public Projects / Public Policies

The purpose of public policy evaluation is to measure the market and non-market impacts of a project or policy on the community as a whole. In order to objectify the debates, we use tools such as :

Cost-effectiveness analysis ; a tool for optimising public spending to prioritise measures in an action plan.

  • Analysis of disproportionate costs for water bodies impacted by industrial or domestic pollution
  • Economic evaluation of the programme of measures of the SDAGE 2016-2021 of Martinique
  • Revision of the Water Development and Management Directive Plan (SDAGE 2022-2027) for Martinique

Cost-benefit analysis ; a tool for assessing the economic profitability of a public policy or project. Cost-benefit analysis aims to integrate into the economic evaluation the non-market costs and benefits, measuring the impacts of the project or public policy on the community as a whole. For example, the studies carried out by the IREEDD :

  • Approach to the total economic value of Port-Cros National Park
  • Approach to the total economic value of the Guadeloupe National Park
  • Cost-benefit analysis of the programmes of measures for the water bodies of the RMC basin
  • Socio-economic justification for not achieving the objectives of the Water Framework Directive

The assessment of willingness to pay or willingness to receive for market goods and services, but also for non-market goods and services :

  • Evaluation of the willingness to pay for recreational uses of Port-Cros National Park
  • Evaluation of the willingness to pay for recreational uses of the Guadeloupe National Park
  • Experimentation of payments for environmental services on the Valière priority catchment
  • Preliminary study of payments for environmental services in the agglomeration of the Pays de Dreux



Financial analysis

The purpose of financial analysis is to shed light on the economic and financial equilibrium of an institution or a public service. In the context of public water and sanitation services, as in other public services, financial analysis leads to the evaluation of the user's contribution to the financing of the service, but also to the determination of equilibrium prices. Among our most significant references, our teams have carried out the following studies :

  • Study of the recovery of costs of services related to water use in the metropolitan and overseas basins (Guadeloupe, French Guiana, Reunion, Martinique, Mayotte)
  • Numerous studies on the Transfer of Water and Sanitation Competence (TCEA)
  • Modelling of water services and rural environments for the Office des Forages Ruraux (OFOR) in Senegal
