- Around 1.6 billion people depend on forests for their livelihood. This includes some 70 million indigenous people
- Forests are home to more than 80 per cent of all terrestrial species of animals, plants and insects

Life On Land
Forests cover 30 per cent of the Earth's surface and in addition to providing food security and shelter, forests are key to combating climate change, protecting biodiversity and the homes of the indigenous population. Thirteen million hectares of forests are being lost every year 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. Efforts are being made to manage forests and combat desertification.
What's the goal here?
To sustainably manage forests, combat desertification, halt and reverse land degradation, and halt biodiversity loss.
Facts & figures
Forests
Desertification
- 2.6 billion people depend directly on agriculture, but 52 per cent of the land used for agriculture is moderately or severely affected by soil degradation
- As of 2008, land degradation affected 1.5 billion people globally
- Arable land loss is estimated at 30 to 35 times the historical rate
- Due to drought and desertification each year 12 million hectares are lost (23 hectares per minute), where 20 million tons of grain could have been grown
- 74 per cent of the poor are directly affected by land degradation globally
Biodiversity
- Of the 8,300 Animal breeds known, 8 per cent are extinct and 22 per cent are at risk of extinction
- Of the over 80,000 tree species, less than 1 per cent have been studied for potential use
- Fish provide 20 per cent of Animal protein to about 3 billion people. Only ten species provide about 30 per cent of marine capture fisheries and ten species provide about 50 per cent of aquaculture production
- Over 80 per cent of the human diet is provided by plants. Only three cereal crops - rice, maize and wheat - provide 60 per cent of energy intake
- As many as 80 per cent of people living in rural areas in developing countries rely on traditional plant-based medicines for basic healthcare
- Micro-organisms and invertebrates are key to ecosystem services, but their contributions are still poorly known and rarely acknowledged
Why?
Forests cover nearly 31 per cent of our planet's land area. From the air we breathe, to the water we drink, to the food we eat-forests sustain us. Think about it. Around 1.6 billion people depend on forests for their livelihood. Almost 75 per cent of the world's poor are affected directly by land degradation. Did you know that forests are home to more than 80 per cent of all terrestrial species of animals, plants and insects? And of the 8,300 Animal breeds known, 8 per cent are extinct and 22 per cent are at risk of extinction. Biodiversity and the ecosystem services it underpins can also be the basis for climate change adaptation and disaster risk reduction strategies as they can deliver benefits that will increase the resilience of people to the impacts of climate change. Forests and nature are also important for recreation and mental well-being. In many cultures, natural landscapes are closely linked to spiritual values, religious beliefs and traditional teachings.
What would it cost to correct the problem?
The UN Forum on Forests Secretariat estimates that achieving sustainable forest management on a global scale would cost US$70-$160 billion per year. The Convention on Biological Diversity estimates that US$150-$440 billion per year is required to halt the loss of biodiversity at a global level by the middle of this century.
What would it cost if we don't correct the problem?
Biodiversity delivers multiple services from local to global levels, while responses to biodiversity loss range from emotional to utilitarian. For instance, insects and other pollen-carriers are estimated to be worth more than US$200 billion per year to the global food economy. Three-quarters of the top-ranking global prescription drugs contain components derived from plant extracts, which would be threatened. Natural disasters caused by ecosystems disrupted by human impact and climate change already cost the world more than US$300 billion per year. Deforestation and forest degradation results in loss of habitat for all species, a decrease in freshwater quality, an increase in soil erosion, land degradation and higher emissions of carbon into the atmosphere. In short, not taking action on forests impacts both the health of the planet and our communities.
What can we do?
Inevitably, we change the ecosystems we are a part of through our presence-but we can make choices that either affirm diversity or devalue it. Some things we can do to help include recycling, eating a locally-based diet that is sustainably sourced, consuming only what we need, and limiting energy usage through efficient heating and cooling systems. We must also be respectful toward wildlife and only take part in ecotourism opportunities that are responsibly and ethically run in order to prevent wildlife disturbance. Well-managed protected areas support healthy ecosystems, which in turn keep people healthy. It is therefore critical to secure the involvement of the local communities in the development and management of these protected areas.

The Sustainable Development Goals aim to end poverty, protect the planet, and ensure prosperity for all. As such, the 17 SDGs and its associated 169 targets do not stand alone, but are are interconnected. The key to success on one will involve tackling issues more commonly associated with another.
