As storms intensify, Mozambique bets on mangroves for climate protection

 

In southern Mozambique, where nearly 60 per cent of mangroves have vanished since 2000, local women are leading a powerful restoration effort, reviving coastal forests that shield communities from extreme weather. As tropical storms worsen, these nature-based solutions are protecting coastlines, and shaping adaptation and biodiversity policies.

What disaster models are still missing

The United Nations Office for Disaster Risk Reduction (UNDRR) is working to integrate social and scientific insights into disaster risk reduction, as vulnerability can shift across groups and contexts. Recognizing these dynamic risks will help build more inclusive, equitable, and effective resilience models.

How Canada’s biggest city built an urban forest

Toronto is Canada’s largest and fastest-growing city — and a rising leader in urban ecosystem restoration. A former  quarry has been transformed into a 16-hectare urban forest, helping Toronto earn recognition from the UN Environment Programme (UNEP) by placing nature at the heart of urban life.

A global agreement to tame chemical pollution

Many chemicals are woefully mismanaged, often allowed to escape into the environment where they wreak havoc on ecosystems and contribute to millions of human deaths every year. The world’s first comprehensive agreement on chemicals and waste aims to reduce these harms.

Tackling climate change with sustainable transport

Transport drives nearly 14 per cent of global emissions. From walkable cities to clean fuels across land, sea, and air, sustainable transport can cut pollution and protect our health. Overcoming fossil fuel dependence and policy gaps is essential to make it happen.

International Day of Combating Sand and Dust Storms

Sand and dust storms originate from natural sources like deserts, dry lake beds, and coastal regions with loose sediment, but they can be exacerbated by human activities like construction and agriculture that strip vegetation and expose soil to wind erosion. Climate change amplifies the occurrence of sand and dust storms by altering weather patterns and reducing vegetation cover, putting lives and livelihoods at risk. Early warning systems are key to reducing the impacts of these storms.

High-level Political Forum on Sustainable Development

The High-level Political Forum on Sustainable Development (HLPF) is the central UN platform for the follow-up and review of the 2030 Agenda for Sustainable Development and the SDGs. HLPF 2025 will convene under the theme “Advancing sustainable, inclusive, science- and evidence-based solutions for the 2030 Agenda for Sustainable Development and its Sustainable Development Goals for leaving no one behind” and will review Goal 14 on Life Below Water, along with Goals 3, 5, 8, and 17.

International Day of the World’s Indigenous Peoples

Indigenous Peoples' territories contain 11 per cent of the world’s forests and most of the world’s remaining biodiversity. The International Day of the World’s Indigenous Peoples highlights the need to protect their rights, celebrate their unique and rich cultures, and recognize their achievements and contributions to preserving the world’s precious ecosystems.

 

Climate action starting now

Everyone has a role in climate action. At the United Nations, we are calling on people everywhere to work together to solve climate challenges and realize the commitments of the 2015 Paris Agreement. This website keeps up with actions taken by governments, businesses, civil society, youth and more in every part of the world.
