Our land. Our future.

All over the world, ecosystems are threatened. From forests and drylands to farmlands and lakes, natural spaces on which humanity’s existence depends are reaching a tipping point.

According to the , up to 40 per cent of the planet’s land is degraded, directly affecting half of the world’s population. The number and duration of  has increased by 29 per cent since 2000 – without urgent action, droughts may affect over three-quarters of the world's population by 2050.

Land restoration is a key pillar of the  (2021-2030), a rallying call for the protection and revival of ecosystems all around the world, which is critical to achieve the .

This?is why??2024 focuses on land restoration, halting desertification?and building drought resilience under the slogan “Our land. Our future. We are #GenerationRestoration.”  We cannot turn back time, but we can grow forests, revive water sources, and bring back soils. We are the generation that can make peace with land.

2024 will mark the 30th anniversary of the UN Convention to Combat Desertification. The sixteenth session of the Conference of the Parties (COP 16) to the United Nations Convention to Combat Desertification (UNCCD) will be held in the Saudi capital, Riyadh, from 2 to 13 December 2024.

What is World Environment Day?

Led by the United Nations Environment Programme (UNEP) and held annually on 5 June since 1973, is the largest global platform for environmental public outreach and is celebrated by millions of people across the world. In 2024, it is hosted by Saudi Arabia.

Why take part?

Time is running out, and nature is in emergency mode. To keep global warming below 1.5°C this century, we must halve annual greenhouse gas emissions by 2030. Without action, exposure to air pollution beyond safe guidelines will increase by 50 per cent within the decade and plastic waste flowing into aquatic ecosystems will nearly triple by 2040.

We need urgent action to address these pressing issues.

A moment of truth for climate action

SG banner for World Environment Day

As climate records are shattered, and emissions continue to rise, the UN Secretary-General will set out some hard-hitting truths about the state of the climate, the grotesque risks leaders are taking, and what companies and countries – particularly the G7 and the G20 – need to do over the next eighteen months to salvage humanity’s chances of a livable future.

Did you know?

  • Every five seconds, the equivalent of one football pitch of soil is eroded. Yet, it takes 1,000 years to generate 3 centimeters of topsoil.
  • Trees in urban areas can cool the air by up to 5°C, reducing air conditioning needs by 25 per cent.
  • Lakes, rivers and wetlands hold 20–30 per cent of global carbon despite occupying only 5–8 per cent of its land surface.

The UN Decade on Ecosystem Restoration focuses on eight major types of ecosystems that we have dangerously degraded. Each can be restored by reducing the pressures they face and with on-the-ground action to speed their recovery. Read all about the challenges and opportunities for each ecosystem in the and the

Land  as an essential carbon sink because its surfaces, such as forests, regulate the planet’s temperature and help to store carbon. But our land is under increasing pressure from deforestation, urbanization, industrial development, agricultural expansion and unsustainable farming practices. The good news is that there are ways to improve land degradation. Read more about climate change.
