15. Life on land
Forests cover 30% of the Earth’s surface. In addition to providing food security and shelter, they are key to combating climate change, and to protecting biodiversity and the homes of the indigenous population. Every year, 13 million hectares of forests are being lost, while the persistent degradation of drylands has led to the desertification of 3.6 billion hectares.
Deforestation and desertification —caused by human activities and climate change— pose major challenges to sustainable development and have affected the lives and livelihoods of millions of people in the fight against poverty.
