BRGM is the French Geological Survey and France’s leading public institution in the field of Earth Science for the sustainable management of natural resources (including water resources) and surface and subsurface risks. This activity is carried out through research activities, support to public policies, and international cooperation with companies and foreign research institutions. BRGM employs over 1,100 people, including more than 700 researchers and engineers. "BRGM’s research activities aim to provide support for public policies and decision making, and to develop innovations (

BRGM acts as technical adviser of water related Ministries ‐ Environment, Health, Industry, Agriculture, Basin Water Agency and local authorities in France and abroad. It is presently involved in the enforcement of European Water Directives. BRGM is acknowledged within France as a leading authority on Water Management and Survey, Soil Protection, Local Point Pollution, Environmental Monitoring (on groundwater resources, soil, industrial sites). BRGM acts also as referent to the National Direction of Risk Prevention of the Ministry for Environnement by implementing research programmes and decision-support tools designed to anticipate and prevent geological risks.

Researchers contributing to NAIAD belong to both the Water, Environment and Ecotechnologies Division, the risk division and the local action division, they are specialized in agricultural and environmental economics, hydrogeologics, natural hazard and risk assessment. They have extensive experience in hydro-economic modeling, environmental economics valuation methods, and participatory foresight approaches applied to groundwater management, planning and policy in European and non-European countries. They conduct and take part in numerous research projects on water management with a particular effort to combine both modeling and participative approaches on regional case studies. The Risks and Prevention Division implicated in this call develops knowledge on geological hazards (such as slope movements, erosion, clay shrinking and swelling – CSS, and coastline retreat) and their impacts on human activities. As well it treats with the impacts of climate change on these risks. At regional scale, researchers and engineers of BRGM’s local agencies, close to stakeholders, bring support for realization of programs and dissemination of results.


BRGM has an important involvement in NAIAD with several roles:

Contribution to WP2.
Hydrogeological research to develop a conceptual and numerical model to account for managed aquifer recharge (MAR) for improving water level level security (model that will be implemented in the french DEMO). The model should be able to simulate expected global changes in a dynamic way under transient conditions, taking into account the temporal variability of water availability (seasonal rainfall, high flow in rivers) and water usage (irrigation during water stress conditions and increasing drinking water supply periods). The conjunctive use and management of both surface and groundwater will be analysed using this modeling approach.
Research on clay shrinking and swelling will focus on the incidences of groundwater conditions on phenomena and thus be able to link water related ecosystems to with this risk. Risk assessment should take in account relative influences of climate variation (temperatures), soil occupation, groundwater level & variations on hazard in order to evaluate associated risk for constructions. Statistical spatial analysis on referenced damages from several past years will provide data to propose a hydro-geotechnical based model to estimate influence of water table level on consequences of phenomena. On another hand, field measurements will b engaged in order to estimate seasonal variations on water content of unsaturated soil and evaluate the induced suction - mainly responsible of shrink, regarding water table level.

Contribution to WP3 (Social).
BRGM will follow WP3 and give feedback concerning the french DEMO experience and stakeholders.

WP4 Leader.
This role will consist in consolidating a general methodology that will be implemented on the DEMO sites of NAIAD and that is standardized to assess the insurance value of ecosystems. BRGM in cooperation with other economic partners will develop standardized economic methods to (i) account for damages caused by water related risks with a particular attention on indirect damages such as damages to businesses and to farming activity, (ii) valuate co-benefits of NBS (ecosystem services) in monetary terms (iii) conduct cost-benefit analysis that account for costs, avoided damages and co-benefits of green infrastructures and consider physical and economic uncertainty with robustness approaches. As leader BRGM will ensure a certain degree of homogeneity of methods that are effectively implemented and will assist and follow the DEMO developments so as to ensure a possible synthesis on the DEMO findings, learning and experiences.

Contribution to WP5.
BRGM role will consist in confronting the "home" developed methods to existing tools (open acces, insurance (e.g. CCR) models, in order to suggest improvement to tools that will be used by insurance companies. An example will be the integration of the knowledge on groundwater levels to geotechnical drought models causing housing damage. This work will require a strong cooperation between developers and end-users.

Contribution to WP6.
BRGM will be in charge of the developments on the french DEMO site 2 (Bievres Liers Valloire). The work will enable to both provide an economic and technical demonstration of the insurance value and role of nature based solutions with respect to different risks in collaboration with CCR (risk and damage data and models). BRGM will thus implement risk assessment methods developed in WP2 (e.g. geothechnical) and economic assessment methodologies (WP4) as well as the exploration of the feasibility of instruments so as to internalize the insurance value in the economy (e.g. mitigation banking, payment for environmental services etc.) in close collaboration with WP7 and 8.

Contribution WP7.
BRGM will contribute significantly to help develop methods to explore the potential for instruments for internalizing the insurance value in the economy. It will develop a stakeholder based approach largely focused on workshops at different scales (geographical scales and end users) to discuss the potential of selected instruments based on existing practices (payment for environmental services etc.) and innovative instruments (e.g. natural resources banking).

Contribution WP8.
Policy. BRGM will contribute to the production of policy briefs and roundtables on the basis of the material produced in its DEMO case as well as methodological developments.

Contribution WP9.
It will contribute to the dissemination mainly through a publication effort.


Water Cap & Trade

Water Cap & Trade project consisted of developing and evaluating various water market scenarios for southern Europe (France, Italy, Spain), using a combination of participatory and economic modeling approaches. The project was part of the IWRM EraNet programme, funded by various National Agencies. It was coordinated by Brgm. (see )

The CARAC’O project (funded by the Rhône-Méditerranée and Corse Water agency) consisted in characterising benefits associated to the protection of groundwater strategic areas for future water supply. The approach consisted in valuating present ecosystem services associated to the protection of the groundwater strategic areas.

The MISEEVA project (funded by the French National Research Agency) consisted in assessing the benefits of adapting to sea level rise at the scale of a French Mediterranean coastal area, by integrating ecosystem services in the valuation framework.
