Combat Climate Change: The Critical Role of Forest Restoration in a Sustainable Future

Nature-based solutions (NbS), like forest restoration, are effective and economical ways to fight climate change. These ecosystems sequester carbon and offer ongoing benefits for biodiversity and local communities, making them vital for our global climate goals.

Forests are a major part of our planet, covering one-third of the Earth’s land. They are home to 80% of terrestrial species and crucial for human survival. A 2023 report from the UN Environment Programme (UNEP) highlights that about 1.6 billion people rely on forests for food, water, and jobs, with these resources valued at approximately $150 trillion. Alarmingly, around 90% of people living in extreme poverty depend on forests to survive.

Forests also play a critical role in mitigating climate change through carbon sequestration. Trees absorb carbon dioxide (CO2) and store it in their biomass. The World Wildlife Fund found that between 2001 and 2019, forests absorbed 18% of human-caused emissions each year. Furthermore, a 2020 report from the Food and Agriculture Organization of the United Nations estimates that global forests store about 662 gigatonnes of carbon, making up around 44% of the world’s carbon stock in forests.

However, rapid deforestation poses a serious threat, contributing to nearly 15% of global carbon emissions. If we don’t stop deforestation, targets like those set by the Paris Agreement may become impossible to reach.

Restoring damaged forests not only enables them to absorb carbon again but improves soil health, water cycles, and wildlife habitats. Unlike costly high-tech carbon capture solutions, forests offer a reliable and time-tested method for carbon storage.

As forests decline, industries like timber and agriculture face a shortage of resources, leading to decreased profits. The UNEP shows that financial institutions are also at risk due to potential defaults from companies relying on forest resources. Deforestation can also increase natural disasters, threaten clean water, and jeopardize the medicinal plants that support local communities.

Global efforts to restore forests are already underway. The UN Decade on Ecosystem Restoration showcases projects aimed at helping local communities and biodiversity. Notably, the Trinational Atlantic Forest Pact restores crucial forests across Brazil, Argentina, and Paraguay, reclaiming over 700,000 hectares and restoring habitats for endangered species.

In Africa, the ambitious Great Green Wall aims to restore 100 million hectares across 20 countries, generating green jobs while tackling climate change. Since 2007, about 30 million hectares have been restored, though challenges remain, such as funding shortages and humanitarian issues highlighted during the 2022 UN Summit.

In India, the Namami Gange initiative is rejuvenating the Ganges River basin by restoring 30,000 hectares and targeting a reduction of 7 million tons of greenhouse gases by 2030. Additionally, the agroforestry systems in Central America are improving soil health, while China’s Shan-Shui Initiative is promoting large-scale ecological restoration.

Indigenous Peoples and Local Communities (IPLCs) play a crucial role in forest stewardship. A study from 2000 to 2012 showed that deforestation rates on Indigenous lands were significantly lower than in other areas. Currently, about 36% of the world’s intact forests exist on Indigenous lands, emphasizing the need to respect their traditional knowledge.

The World Bank highlights that collaborative efforts, like those seen in Canada and Nepal, can effectively revitalize these ecosystems while also supporting local livelihoods. Empowering Indigenous communities is essential for sustainable forest management.

In conclusion, forest restoration is more than an environmental necessity; it’s a pathway to sustainable development. By investing in forests and local communities, we can create a balance between people and nature, mitigating climate change and fostering economic growth. While we need further investments and trust in local knowledge, the outlook remains hopeful.
