UN urges intense restoration of nature to address climate and biodiversity crises
Launching the UN Decade on Ecosystem Restoration, a new UNEP/FAO report says the world must deliver on existing commitments to restore at least 1 billion degraded hectares of land - an area comparable to China - in the next decade and add similar commitments for oceans.

Facing the triple threat of climate change, loss of nature and pollution, the world must deliver on its commitment to restore at least one billion degraded hectares of land in the next decade—an area about the size of China. Countries also need to add similar commitments for oceans, according to a new report by the UN Environment Program (UNEP) and the Food and Agriculture Organization of the UN (FAO), launched as the U.N. Decade on Ecosystem Restoration 2021-2030 gets underway.

The report, "Becoming #GenerationRestoration: Ecosystem for People, Nature and Climate," highlights that humanity is using about 1.6 times the amount of services that nature can provide sustainably.

That means alone are insufficient to prevent large-scale ecosystem collapse and biodiversity loss. Global terrestrial restoration costs—not including costs of restoring —are estimated to be at least USD 200 billion per year by 2030. The report outlines that every $1 USD invested in restoration creates up to USD $30 in .

Ecosystems requiring urgent restoration include farmlands, forests, grasslands and savannahs, mountains, peatlands, urban areas, freshwaters, and oceans.

Communities living across almost two billion of degraded hectares of land include some of the world's poorest and marginalized.

"This report presents the case for why we must all throw our weight behind a global restoration effort. Drawing on the latest scientific evidence, it sets out the crucial role played by , from forests and farmland to rivers and oceans, and it charts the losses that result from a poor stewardship of the planet," UNEP Executive Director, Inger Andersen, and FAO Director-General, QU Dongyu, wrote in the report's foreword.

"Degradation is already affecting the well-being of an estimated 3.2 billion people—that is 40 percent of the world's population. Every single year we lose ecosystem services worth more than 10 percent of our global economic output," they added, stressing that "massive gains await us" by reversing these trends.

Ecosystem restoration is the process of halting and overturning degradation, resulting in cleaner air and water, extreme weather mitigation, better human health, and recovered biodiversity, including improved pollination of plants. Restoration encompasses a wide continuum of practices, from reforestation to re-wetting peatlands and coral rehabilitation.

It contributes to the realization of multiple Sustainable Development Goals (SDGs), including health, clean water, and peace and security, and to the objectives of the three "Rio Conventions' on Climate, Biodiversity, and Desertification.

Actions that prevent, halt and reverse degradation are necessary to meet the Paris Agreement target of keeping global temperature rise well below 2 degrees Celsius.

Restoration, if combined with stopping further conversion of natural ecosystems, may help avoid 60 percent of expected biodiversity extinctions. It can be highly efficient in producing multiple economic, social and ecological benefits concurrently—for example, agroforestry alone has the potential to increase food security for 1.3 billion people, while investments in agriculture, mangrove protection and water management will help adapt to climate change, with benefits around four times the original investment.

Reliable monitoring of restoration efforts is essential, both to track progress and to attract private and public investments. In support of this effort, FAO and UNEP also launch today the Digital Hub for the UN Decade, which includes the Framework for Ecosystem Restoration Monitoring.

The framework enables countries and communities to measure the progress of restoration projects across key ecosystems, helping to build ownership and trust in restoration efforts. It also incorporates the Drylands Restoration Initiatives Platform, which collects and analyzes data, shares lessons and assists in the design of drylands restoration projects, and an interactive geospatial mapping tool to assess the best locations for forest restoration.

Restoration must involve all stakeholders including individuals, businesses, associations, and governments. Crucially, it must respect the needs and rights of Indigenous Peoples and , and incorporate their knowledge, experience and capacities to ensure restoration plans are implemented and sustained.
