An interview with Marie-Cécile Grisard « Living with Rivers »

Alain Boinet: You are launching with IAGF the « Living with rivers » campaign, could you present this initiative.

Marie-Cécile Grisard: Launched on 20 June, Living with Rivers is the first public and international mobilisation entirely dedicated to rivers. This first edition will focus on three major rivers: the Rhône, the Saint Lawrence and the Senegal River. The aim is to listen to the voices of those who know or work with them on a daily basis : experts, artists, infrastructure managers or waterway users, sportsmen and women… and above all, local residents. By crossing approaches, and linking knowledge and emotion, we want people to “listen to the voices of rivers”, these living entities that have so much to tell us about our past, our present and our future. It is essential that our societies change their view of rivers and, at the very least, that they take a better look at the rivers that flow through their cities and territories, which are too often ignored or misunderstood!

Living with Rivers also aims to highlight concrete solutions for the preservation of rivers and making people understand that everyone has a role to play. All these testimonies will reveal the strategic role of river ecosystems in meeting global challenges: food resilience, health security, decarbonised energy, green mobility, maintaining biodiversity, etc.

The IAGF, of which Erik Orsenna is President, is already five years old. What is your diagnosis of these major rivers today? What are the ills and risks that threaten them and are the problems the same for everyone or are there different situations and solutions?

Our observation is that rivers are in trouble, and this is true throughout the world. The risks are twofold. Climate change, which makes freshwater resources even more fragile; and the pressures exerted directly by man on these ecosystems, both in terms of quality and the volume of water available for all uses. How can we accept all of the benefits of a river – irrigation, transport, energy, but also other more intangible benefits such as landscapes or rituals – without destroying the source forever? How can we withdraw water without exhausting it? Water consumption increased sixfold between 1990 and 2010 and is expected to increase by a further 55% by 2050. All our work within the IAGF is to find the best balance between exploiting rivers and respecting them.

It is important to understand that the threats are not only to rivers, but to all living systems. Our health depends on the health of rivers. Water-related crises – whether due to a lack of water or too much water – will multiply with the impacts of climate change and lead to numerous associated crises: social, economic and geopolitical.

Even if there are specificities according to the rivers, this observation applies on a global scale. IAGF’s raison d’être is to build bridges between knowledge and solutions from one country to another in order to collectively manage rivers more sustainably.

What links and relationships do large rivers have with their ecosystems (springs, rivers, groundwater), their environment (waste, plastic, pollution, etc.) and with the oceans at a time when a United Nations conference is being held in Lisbon on this subject?

It is indeed crucial to have a systemic vision, from the source to the ocean, when dealing with the issue of water. For example, it is estimated that 80% of plastic pollution found in the sea comes from rivers. This is why, for example, IAGF launched, with the Tara Ocean Foundation and the manager of the Rhône River, CNR, the “Plastic-free river, protected ocean” charter for mayors . The solution to plastic is found on land, at the source of pollution!

Another example concerns cities, where it is necessary to better integrate the water cycle into development projects. Architects, urban planners and engineers must rely on solutions offered by nature in the city to invent a more resilient city, which uses the functions of infiltration, evapotranspiration, storage, retention and runoff of water and which returns water to the soil. We need to better accept and use water as a resource, not as a hazard or waste. Living with it rather than trying to control it: this should be the motto of urban policies on water and river management.

What is the role of rivers in the great water cycle and how important is it?

Rivers play a crucial role in the great water cycle. They contribute to its stability in a global way and we must be vigilant to the acceleration of this cycle on a global scale. We are seeing extreme weather phenomena increase in intensity and frequency and we are not at all prepared for this! Look at the dramatic consequences of the floods in Germany and Belgium last year. Or the hardening of positions on resource sharing between countries, as with the Grand Renaissance dam in Ethiopia, or between stakeholders, as on the subject of basins in France. It is urgent to act so that water remains an ally and a source of cooperation!

What are the synergies of IAGF and your campaign with other water actors, such as the FWP in France and around the world?

Our messages only make sense if they are integrated into the discourse carried out in France and internationally by integrated networks of actors, for greater efficiency. Rivers are an important part of the hydrosphere, so we need to know how to carry out joint projects with other freshwater and saltwater stakeholders to find sustainable solutions. In the same way, we are always keen to bring all the stakeholders to the table for concerted solutions.

This approach of dialogue and openness is of course reflected in the Living with Rivers mobilisation: its organising committee is large and the partners numerous. Our idea is to federate energies, to enhance local initiatives and not to replace them. We are stronger together!

What form will this campaign take, what is its agenda and its culmination?

Living with Rivers began in a digital format, with original content posted on the social networks Instagram and Twitter, and the publication of testimonials and stories on our website. Our first objective is to create a community that has a common interest in rivers, whether emotional or professional, and to bring in others who are less familiar with the subject. To do this, there is nothing like being surprised and immersed in the cultures and stories of the people who live the river as closely as possible!

We will also relay the events of all our partners this summer on the international scene, around the Senegal River (Mali, Mauritania, Guinea, Senegal), the St. Lawrence (United States, Canada) and the Rhône (Switzerland, France). This effervescence of views and ideas will culminate in the closing event Living with Rivers at the Musée des Confluences in Lyon on 27 October. This interactive evening, which will be broadcast in France and abroad, will bring together all those involved in the defence of rivers and will make a universal plea for their protection. This evening will also be part of the programming of the museum’s new exhibition, “Nous, les fleuves”, of which IAGF is a partner.

How would you like to conclude this interview?

Join this worldwide mobilisation around rivers! We are curious to know your relationship with the river and count on your commitment to their future, and therefore also ours! #livingwithrivers
