Wetlands are our “life insurance” against the combined climate and biodiversity crises

Wetlands are our “life insurance” against the combined climate and biodiversity crises

On the occasion of the Climate and Ramsar COPs taking place in Egypt and Switzerland, several associations and personalities warned on the imminent danger if we persist to neglect wetlands and stressed the urgency need to give a new impetus to the protection of wetlands as real nature-based solutions to climate change and biodiversity erosion.

2022 is about to break all records – temperatures, heat waves, droughts – in Europe, revealing the vulnerability of our agriculture, our forestry management, our energy mix and our economies to these phenomena that have long been predicted by scientists but poorly anticipated.

The Rhine, the Loire, the Po, but also the Yangtze and Parana… so many previously powerful rivers that this summer were only ghosts slipping through a bed of sediments cracked by the sun.

At the same time, reports are accumulating attesting to the accelerated collapse of biodiversity, the living fabric of the planet. The number of vertebrate populations on the planet has decreased by 69% since 1970, and this collapse has reached 83% for freshwater species1, a sign of the massive destruction of wetlands.

These two crises, climate and biodiversity, are intimately linked and feed each other. They are the two facets of a systemic crisis that has its roots in our erroneous relationship with the living world. A relationship “against Nature”, against these millions of species of which we are an integral part, dependent and interdependent.

It is in this context of unprecedented tensions that an unprecedented series of international events dedicated to nature and climate is unfolding in the space of only a few weeks: the Conferences of the Parties (COP) of the intergovernmental treaties on wetlands2, climate3, trade in species4 and finally biodiversity5.

This sequence is a unique opportunity to freeze the image, to question the commitments, the ambitions and the articulations between these treaties… and to better move forward.

An urgent transition, but hampered by too much resistance

There is no shortage of reasons for concern as these international meetings approach: The rate at which wetlands are disappearing around the world is not slowing down despite repeated commitments by States; a recent UNEP report6 on climate shows that the international community’s progress is “woefully inadequate” to chart a credible course towards achieving the objectives of the Paris Agreement. On the biodiversity front, after the obvious failure of the Aïchi targets, which were supposed to commit to the recovery of biodiversity during the 2011-2020 decade, the new framework that is taking shape for the current decade looks too unambitious and still sorely lacks a mechanism for holding states accountable.

Inventing a new way of sharing water by placing life at the center

Water grabbing in the plains in mega-basins or in the mountains to produce artificial snow, the “swan song” of agricultural or tourist actors who refuse to adapt to the inevitable. Impossible trade-offs between crop irrigation, hydroelectric production, cooling of nuclear power plants, domestic or industrial uses when faced with water that is too scarce to satisfy the various needs to which our production and consumption models have accustomed us.

It is urgent to accept the obvious, to reconsider our relationship with water and with living beings, and to change our behaviors that deeply affect the great water cycle. Faced with growing needs and a water availability that is less and less predictable and controllable, we must reinvent its uses and its sharing, leaving its fair share to nature. This nature that we must no longer consider as an adjustment variable of our production systems, but as their foundation, as the basis of our lives and our economies.

Wetlands, providers of solutions to growing societal challenges

Wetlands, long perceived as unhealthy, are the most destroyed ecosystem on the planet, declining three times faster than forests. But as they disappear, they are proving to be the ecosystem that contributes most to humanity. More than a billion people depend directly on them for their existence and many more benefit from their extraordinary powers. They are the “kidneys of nature”, purifying the water we pollute. Gigantic sponges, they capture the increasingly irregular and often massive precipitation, attenuate the peaks of floods recharge the water tables and support the flow of rivers during longer and more intense droughts. Hydrologists agree that the most effective and sustainable way to store water and make it available for a variety of uses is to ensure that groundwater and wetlands are fully functional and interconnected.

At a time when societal challenges – food security, climate change, water supply, human health… – have never been more intense, there is an urgent need for massive wetland protection and restoration. These are highly effective, low-cost solutions with multiple collateral benefits. Nature-based Solutions. Our life insurance.
