An urgent global warning has been issued by the United Nations Environment Programme (UNEP): tropical forests are at high risk of loss. About 391 million hectares of tropical forests, or roughly a quarter of the world’s total forest area, are thought to be seriously threatened by deforestation, according to the paper In High-Risk Forests, High-Value Returns — Co-Benefits Assessment for Decision-Makers.
About 53 million people live within five kilometers of these forests, and they provide them with fuel, food, water, and a means of subsistence. But because of human endeavors like logging, farming, and infrastructural development, these natural habitats are vanishing quickly. According to UNEP’s research, preserving these forests is essential for both biodiversity and reaching climate goals, especially lowering the annual amount of carbon dioxide equivalent (GtCO2e) by one gigatonne.
Given that the annual loss rate is approaching 10 million hectares, equivalent to the area of South Korea, the research emphasizes the critical need for conservation, sustainable management, and restoration to prevent ecosystem collapse and global economic losses.
Why Are These Forests Considered High-Risk?
“High-risk forests” are defined by the UNEP as regions with significant ecological services, high carbon stores, and a high probability of deforestation. Because they control the global temperature and act as carbon sinks, these forests are vital.
Key reasons tropical forests are at high risk of loss:
- Massive Carbon Stocks: These areas contain billions of tons of carbon that could accelerate climate change if released.
- High Deforestation Pressure: Massive forest removal is fueled by mining, logging, and agricultural growth.
- Vital Ecosystem Services: They preserve water quality, control rainfall, and stop soil erosion.
- Population Dependence: These woods provide food, water, fuelwood, and medication for over 53 million people, who depend on them for everyday survival.
Africa has the greatest concentration of people living near forests. In contrast, the Asia-Pacific region has the highest concentration of people living near forests in high-risk areas, according to UNEP.

Approximately equal to the size of the European Union, these 391 million hectares of tropical forests are at high risk of loss, according to UNEP’s research.

How Do Tropical Forests Support Climate and Water Systems?
As the planet’s green lungs, tropical forests cycle water, absorb carbon, and maintain ecosystem stability. Approximately half of all fossil fuel emissions, approximately 13.1 ± 1.4 GtCO2e year, were absorbed by worldwide forests between 1990 and 2019.
Benefits of tropical forests to the climate and ecosystem:
- Rainfall Recycling: To keep rivers flowing and support agriculture, forests recycle 10–14% of rainfall.
- Flying Rivers Phenomenon: The phenomenon known as “flying rivers” is caused by the Amazon’s forests, which create enormous air currents that carry moisture thousands of kilometers away, guaranteeing rainfall in far-off agricultural areas.
- Nutrient Retention: They prevent pollution that leads to fish fatalities and algae blooms by retaining roughly 2.3 million tons of nitrogen every year.
- Soil Protection: These ecosystems prevent 527 million tonnes of soil from being washed away annually, equivalent to the sediment that would fill 150,000 Olympic-sized pools.
- Water Security: River flow and groundwater recharge are guaranteed by forest cover, which is essential for irrigation, hydropower, and drinking water.
UNEP cautions that a tipping point is approaching for this fragile balance. 20–40% deforestation in the Amazon might reduce precipitation and decrease the forest-rainfall feedback, turning rainforests into savannahs, which would have disastrous climate effects.
Thus, preserving and replenishing forest cover is essential to water security on a local and global scale. Preserving these ecosystems may be the difference between irrevocable devastation and climatic stability.

What Are the Economic and Social Implications of Forest Loss?
According to the UNEP research, tropical forests are at high risk of loss, both economically and environmentally. Destroying them can result in decreased agricultural output, more flooding, and yearly GDP losses of billions of euros.
Economic and livelihood benefits of conserving high-risk forests:
- Food Security: Crops pollinated by forest insects provide food for more than 10 million people each year.
- Fuel and Resources: In addition to fruits, nuts, fiber, and medicinal plants, these woods annually supply 111 million tonnes of fuelwood.
- Employment and Income: Forest products provide a living for over 25 million materially impoverished people, including women and Indigenous populations.
- Disaster Prevention: By stabilizing soils and reducing runoff, forests help to prevent floods, landslides, and storm damage.
- Economic Savings: By averting damage to houses, farms, bridges, and highways, protecting high-risk forests helps to prevent $81 billion in GDP losses per year.
These figures demonstrate that forest conservation is not only a necessary environmental measure but also a business one. According to UNEP, protecting forests has significantly more advantages than disadvantages and offers crucial “co-benefits” for biodiversity, climate resilience, and human welfare.

How Can Nations Protect High-Risk Tropical Forests Effectively?
To protect threatened forests, governments, corporations, and local communities must act quickly and cooperatively, according to UNEP. The study provides a paradigm that puts human welfare and conservation first.
UNEP-recommended strategic actions include:
- Boost Forest Governance: Protect Indigenous land rights and enforce anti-deforestation legislation.
- Promote Sustainable Agriculture: Reduce land conversion for large-scale farming and encourage agroforestry to advance sustainable agriculture.
- Carbon Finance Mechanisms: Expand REDD+ and comparable carbon credit schemes to reward forest protection.
- Invest in Restoration: Reforest degraded areas to improve carbon absorption and ecosystem services.
- Empower Local Communities: Offer rewards for alternative livelihoods and the sustainable use of resources.
The research emphasizes that although tropical forests are at high risk of loss, they also offer one of the most significant opportunities to slow down global warming. Humanity could reduce annual carbon emissions by a gigatonne while maintaining vital ecosystem services by conserving just 391 million hectares.

Frequently Asked Questions (FAQs)
Q1. What is the significance of tropical forests in regulating the climate?
They serve as enormous carbon sinks, absorbing around half of the emissions from fossil fuels worldwide and controlling the cycles of rainfall and temperature.
Q2. What are “high-risk forests” according to UNEP?
These forests have a great capacity to store carbon, provide critical ecological services, and are highly vulnerable to destruction from human activities like agriculture and logging.
Q3. How might local populations profit from the preservation of these forests?
By averting natural disasters, maintaining biodiversity, and supplying fuel, food, clean water, and economic possibilities, forest conservation supports livelihoods.
