Protect, restore and promote sustainable use of terrestrial ecosystems, sustainable forest management, combat desertification, stop and reverse land degradation, and stop the loss of biodiversity.

Forests occupies 30% of the earth's surface. In addition to ensuring food security and providing protection, forests are also vital to combat climate change and protect biodiversity. At the same time, it is also the home of indigenous people. The forest area is reduced by 13 million hectares each year, and the continuous degradation of dry land has led to the desertification of 3.6 million hectares of land. Deforestation and desertification caused by human activities and climate change pose major challenges to sustainable development and affect the livelihoods of millions of people and efforts to alleviate poverty. Efforts are currently being made to manage forests and combat desertification.

       Status of forest resources:

       ●  1.6 billion people, including more than 2,000 indigenous cultures, rely on forests for their livelihoods

       ●  More than 80% of terrestrial animals, plants and insects live in forests

      Desertification threat:

       ●  2.6 billion people directly depend on agriculture for their livelihoods, but 52% of agricultural land is affected or severely affected by soil degradation

       ●  Land degradation affects 1.5 billion people worldwide

       ●  The rate of cultivated land loss is estimated to be 30 to 35 times the historical rate

       ●  Due to drought and desertification, the world loses 12 million hectares of arable land every year (23 hectares per minute), which could have produced 20 million tons of food

       ●  74% of the world’s poor are directly affected by land degradation

      Biodiversity challenges:

      ●  Among the 8,300 known animal species, 8% are extinct and 22% are endangered

      ●  Among 80,000 tree species, less than 1% are studied as potential use objects

      ●  Fish provide about 3 billion people with 20% of animal protein. Only 10 species account for 30% of the output of marine fishing fisheries, and only 10 species account for 50% of the output of aquaculture fisheries

      ●  More than 80% of human diet comes from plants. Only 5 food crops provide 60% of human energy intake

      ●  Microbes and invertebrates are vital to ecosystem services, but people still don’t understand or agree with their various contributions
