Developing and managing floodplains in a context of global change

Why floodplains in a context of global change?

Floodplains, including deltas, are among the most densely populated regions in the world. They are crucial in terms of food security because they are home to highly productive agricultural systems, especially rice production. These agro-ecosystems are also extremely vulnerable to flooding and rising sea levels due to climate change. Having been the subject of very significant investment in water resource control infrastructures for nearly 150 years, the sustainability of these areas is now being questioned, calling for new approaches to their development and use.

What do we do?

We have initiated a comparative study of three large floodplains in three countries of the world: the Upper Mekong delta in Cambodia, the Daule floodplain in Ecuador and the irrigated plain of Gharb in Morocco, which represent the diversity of issues faced by floodplains.

In these three socio-ecosystems, we are carrying out studies with national partners that aim to:

  1. Characterise the complex hydrological functioning of these zones;
  2. Identify and assess the multiple services that floodplains provide to people.

We design and conduct participatory activities aimed at renewing territorial development approaches in these areas.
