The world cannot afford to let this year's COP16 biodiversity negotiations pass without significant progress toward protecting critical ecosystems and maintaining the stability of the global water cycle. The costs of inaction are already too high, and the situation is getting worse.
LONDON – While the world’s attention has been on the US election, the rising number of extreme weather events – from disastrous flooding in Spain to southern Africa’s worst drought in a century – highlights the need to remain focused on climate change, biodiversity loss, and a changing water cycle.
These crises are related, and the symptoms are getting worse. When drought kills crops, millions of people suffer; and when water extremes (too much or too little) hit vulnerable societies, the resulting displacements, migration, and conflicts can affect everyone.
Yet no one is listening. The recent COP16 biodiversity summit in Cali, Colombia, received little international attention, and failed to produce a roadmap to ramp up funding for species protection. Instead, delegates merely celebrated their decision to charge private companies for the use of genetic biodiversity information, and to establish a new working group for indigenous peoples.
While important, these developments are marginal in relation to the task of halting biodiversity loss. Worse, they could serve as a smokescreen for global inaction, just as we have seen over the years in global climate negotiations, where long sessions on trade and “loss and damage” obscured the lack of action on phasing out fossil fuels. Although the Global Biodiversity Framework – adopted in Montreal in 2022 – established ambitious targets to protect 30% of the planet by 2030, 158 countries still have not submitted formal plans on how they will do their part.
This inaction cannot continue. Human activities are threatening the stability of the climate and the natural systems upon which human well-being depends. Food security, human health, and social stability are all on the line. The COP16 negotiations are supposed to continue “at a later date”; but the world cannot afford to let COP16 pass without significant progress toward protecting our planet’s biodiversity and ecosystems.
Without urgent, systemic, collective action, the effects of climate change, biodiversity loss, and the water crisis will only intensify. Biodiversity and nature are central to maintaining stable climate patterns and the hydrological cycle. Wetlands and forests, which store huge amounts of carbon, rely on stable water cycles and thriving biodiversity to function effectively.
Similarly, terrestrial ecosystems currently absorb 25% of carbon dioxide emissions, helping to prevent atmospheric CO2 from rising beyond 420 parts per million. Yet extreme hydrological events – droughts and floods, combined with heat during the 2023 “super El Niño” cycle – eroded this massive carbon sink substantially. This was a serious warning sign. Unchecked biodiversity loss alone could cause us to exceed the Paris climate agreement’s target of limiting global warming to 1.5° Celsius, with dire consequences for vulnerable communities worldwide.
In our final report for the Global Commission on the Economics of Water, we show how interconnected our world is not just through the blue water in our rivers and lakes, but also through “green water” in soil moisture. Moreover, we are all connected through “atmospheric rivers”: moisture transported from the soil, through plants and forests, to the atmosphere, where it flows between regions to provide essential rainfall.
Healthy vegetation is the backbone of this process, transpiring water into the atmosphere to generate clouds. Some countries benefit disproportionately from these atmospheric rivers, while others, like India and Brazil, are significant exporters of moisture. Almost half of global rainfall depends on neighboring land use, underscoring the importance of conserving healthy ecosystems worldwide.
The costs of inaction are enormous. A destabilized hydrological cycle implies far-reaching economic damage. Changing precipitation patterns, rising temperatures, reduced water storage, and declining access to clean water augur significant GDP losses. High-income countries face an average GDP contraction of 8% by 2050, and lower-income countries could suffer drops of up to 15%. At the same time, over half (55%) of the world’s food production is now in areas with dwindling freshwater supplies.
We can still turn the tide on the global water crisis, but only by protecting and restoring declining ecosystems. As the commission’s report notes, a good starting point is for governments to adopt a clear set of mission-driven policies to “[c]onserve and restore natural habitats critical to protect green water.” Mission-driven policies that recognize the interdependencies between water and biodiversity are needed to foster the all-of-government and economy-wide responses that planetary sustainability requires.
For example, a mission to “restore at least 30% of degraded forest and inland water ecosystems globally by 2030” would require sectors as diverse as agriculture, forestry, construction, and information and communication technologies (to name a few) to work together. A mission to restore forests is not just for the environment ministry, but also for the finance, agriculture, and science and technology ministries, among others.
Governments have a chance to demonstrate this level of ambition and make meaningful progress when COP16 negotiations resume. First, they must submit formal plans on how they will meet the Global Biodiversity Framework targets. Second, national biodiversity strategies and action plans that set priorities and direct financing streams must recognize the importance of green water.
Third, governments must do more to recognize the rights of indigenous peoples, who are stewards of one-quarter of the planet’s land and about 40% of the remaining natural lands worldwide. While COP16 delegates did agree that companies should compensate local and indigenous communities for the use of genetic information drawn from the biodiversity they help safeguard, the compensation thresholds should be more ambitious.
Tokenistic smokescreens are not evidence of a successful summit. We cannot afford to lose a decade of action on biodiversity. The world’s access to freshwater depends on governments doing more right now.
