Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss

Goal 15 is about conserving life on land. It is to protect and restore terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and stop biodiversity loss.

Earth’s ecosystems are vital for sustaining human life, they contribute to over half of global GDP and encompass diverse cultural, spiritual, and economic values.

However, the world is facing a triple crisis of climate change, pollution and biodiversity loss.

Between 2015 and 2019, at least 100 million hectares of healthy and productive land were degraded every year, impacting the lives of 1.3 billion people.

Agricultural expansion is the direct driver of almost 90 per cent of deforestation. This is in direct relation to our food systems, and oil palm harvesting accounted for 7 per cent of global deforestation from 2000 to 2018.

Global and regional efforts to sustain forest ecosystems as well as their social, economic and environmental functions are essential, in particular for developing countries and the tropics.

We need to shift humanity’s relationship with nature to achieve Goal 15, and realise that nature is the root of our life of earth. The recently adopted Kunming-Montreal Global Biodiversity Framework provides renewed impetus for Goal 15, outlining four outcome- oriented goals to be achieved by 2050 and 23 targets to be achieved by 2030.

Why should we care?

Forests cover nearly 31 per cent of the world and are home to more than 80 per cent of all terrestrial species of animals, plants and insects. However, biodiversity is declining faster than at any other time in human history.

Globally, one fifth of the Earth’s land area are degraded, an area nearly the size of India and the Russian Federation combined. Land degradation drive species to extinction and intensifies climate change, 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.

What does loss of forests mean?

Lost forests mean the disappearance of livelihoods in rural communities, increased carbon emissions, diminished biodiversity and the degradation of land. While forest loss remains high, 2020 data show that the proportion of forests in protected areas and under long-term management plans increased or remained stable at the global level and in most regions of the world.

An irreversible effect of human activity on the environment is species extinction, which upsets the balance of nature and makes ecosystems more fragile and less resistant to disruptions. A recent UN report on biodiversity found that around 1 million animal and plant species are now threatened with extinction, many within decades, more than ever before in human history.

How does it affect our health?

Increased demand for animal protein, a rise in intense and unsustainable farming, the increased use and exploitation of wildlife, and the climate crisis are all driving the increased emergence of zoonotic diseases – diseases transmitted from wildlife to people – like COVID-19.

Every year, some two million people, mostly in low and middle-income countries, die from neglected zoonotic diseases. The same outbreaks can cause severe illness, deaths, and productivity losses among livestock populations in the developing world, a major problem that keeps hundreds of millions of small-scale farmers in severe poverty. In the last two decades alone, zoonotic diseases have caused economic losses of more than $100 billion, not including the cost of the COVID-19 pandemic.

What can we do?

Some things we can do to help include recycling, eating a locally-based diet that is sustainably sourced, and consuming only what we need.

We must 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 therefor critical to secure the involvement of the local communities in the development and management of these protected areas.
