Alain Albrecht

Alain is Director of Research at the IRD in the Eco&Sols unit, for "Functional Ecology and Biogeochemistry of Soils and Landscapes". He is a specialist in tropical soils, more particularly in soil organic matter in its agronomic and environmental functions. His career, which started in 1981, took him to Ivory Coast, Martinique, Kenya, Madagascar and finally Reunion Island. He has had the opportunity to supervise more than 70 students, including about 20 PhD students, mainly in the South. He is the initiator and leader of the SeqCOI project.

Marie Deresse
Project Engineer - Coordination

Marie is a contract project engineer at the IRD, within the Eco&Sols unit, whose main research topics are low-input agroecosystems in tropical and Mediterranean climates. She holds a master's degree in political sociology and a master's degree in public food policy and health risk management. She is in charge of coordinating the SeqCOI project and participates in various actions.

Myriam Allo
Research Officer - Soil Carbon

Myriam is a contract researcher at the IRD within the Eco&Sols unit, based in Saint-Pierre de La Réunion. She holds a PhD in agronomic sciences and did her thesis on the carbon sequestration potential of agricultural soils in Réunion. Within the framework of the SeqCOI project, her mission is to coordinate activities concerning soil carbon mapping and greenhouse gas (GHG) balances in the project's target territories, in order to develop and make available to decision-makers a decision support tool for territorial policies on climate change mitigation.

Pierre Todoroff
Research Associate Spatialization

Pierre is a researcher in agronomy, specialized in spatial information, metrology and landscape agronomy, within the AIDA unit at CIRAD, in Saint-Pierre de La Réunion. He leads a research team specialized in decision support for agriculture in the South. His research interests include soil carbon stock assessment, carbon balance of land use changes, crop growth monitoring by remote sensing, assimilation of remote sensing data into crop models, and spatialized information systems. He works in the Indian Ocean region (Reunion, Mauritius, South Africa, Thailand, Indonesia).

Pierre Villefourceix-Gimenez
Project Engineer - Data

Pierre is a data scientist within the IRD, based in Saint-Pierre (La Réunion). A graduate in statistical and economic engineering and an agronomist, he is in charge of building a spatialized database of the island's soil properties. As part of the SeqCOI project, he will participate in the construction of a similar database including the other study areas; it will contain the parameters required for the operation of the tool for assessing soil carbon supply and demand according to several land-use scenarios.



The Institute of Research for Development is an internationally recognized multidisciplinary organization working mainly in partnership with Mediterranean and intertropical countries.

The IRD is a French public institution under the dual supervision of the Ministries of Higher Education, Research and Innovation and of Europe and Foreign Affairs. It is a major French player on the international development agenda.

The IRD's priorities are in line with the implementation, combined with a critical analysis, of the Sustainable Development Goals (SDGs) adopted in September 2015 by the United Nations, with the ambition of guiding development policies and stepping up to the major challenges related to global, environmental, economic, social and cultural changes that affect the entire planet.

Our partners

In Reunion Island


The CIRAD is the French agricultural research and international cooperation organization for the sustainable development of tropical and Mediterranean regions.

CIRAD is present on every continent in some 50 countries, and draws on the skills of its 1,650 employees, including 1,140 scientists, as well as a global network of 200 partners.

CIRAD uses its expertise so as to promote biodiversity protection, agro-ecological transitions, the sustainability of food systems, health (of plants, animals and ecosystems), and ensure the sustainable development of rural areas and their resilience in the face of climate change.


The DEAL (Department of the Environment, Planning and Housing) is the government service responsible for promoting sustainable development on Réunion Island. It is placed under the authority of the Prefect.

Its fields of action are: sustainable development, planning and construction; energy transition; fight against climate change; preservation of resources, natural spaces, biodiversity, water resources and landscapes; ecological transition; prevention of pollution and technological and natural risks; production of social housing, housing policy and urban renewal; mobility and transport; safety and road safety education; provision of environmental knowledge and data.

It has 260 employees. Its head office is based in Saint-Denis, and 3 territorial branches (Saint-Paul, Saint-Pierre and Saint-Benoît) ensure its presence throughout the department, as close as possible to citizens, local authorities and public or private partners.

In Madagascar


The Laboratory of Radio-Isotopes is attached to the Presidency of the University of Antananarivo. It is integrated in international research networks (collaboration with IRD, CIRAD INRAEthe JIRCAS, Bangor Universitythe VLIR etc.) and national (collaboration withESSAthe FOFIFAFIFAMANOR, ANAE, etc.).

The Laboratory has three main research areas:

"Soils and climate change": studies on the impacts of different usage patterns and agricultural practices on carbon sequestration in the soil and in plant biomass.

"Nutrient bioavailability": studies on improving cultural practices and using different soil/root-plant interactions.

"Soil biology" studies on the role of various soil organisms (soil fauna, microregulators and soil microorganisms) in making nutrients available to the plant and in mitigating climate change via their actions on the carbon cycle. This line of research is part of a close collaboration between the LRI and theUMR Eco&sols (IRD).


The Fades (Promoting the Development of Research and Expertise in Agronomy, Ecosystem Services and Soil) Association is an expert in environmental and agronomic sciences.

In the field of soil sciences, its expertise is focused on the characterization of the various soil properties, their mapping, and the measurement of their greenhouse gas balance and emission potential. 

The Fades association has been commissioned within the framework of the SeqCOI project to carry out an inventory of current and historical data on soil properties and agricultural practices in the study area in Madagascar, and to map the use patterns and carbon stocks of the soil. It will also assess the greenhouse gas emission/storage balance of rice fields.


Agrisud International is a French development NGO whose mission is to fight poverty in the South.

Through an economic and agro-ecological approach, it trains and supports very small family-run agricultural enterprises (VSEs) in the sustainable development of their activities.

Since 1992, it has contributed to the development of family farms and agricultural sectors in 26 countries in Africa, Asia, South America and the Caribbean.

With its partners, it also contributes to reinforcing territorial dynamics so that the environment of these agricultural VSEs is environmentally, socially and economically beneficial.

More than 75,000 VSEs have been supported since its creation.

In Rodrigues Island


The Ter Mer Rodriguez Association focuses its activities on four main areas:

→ Education and awareness campaigns for environmental protection.

→ Capacity building for climate change action in line with the regional, national and international vision, including the 2030 vision for sustainable development.

→ Research and innovation.

→ Promotion of ethical projects.
