Deforestation: 12-15 million hectares of forest are lost each year.


Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter.But forests around the world are under threat from deforestation, jeopardizing these benefits. Deforestation comes in many forms, including fires, clear-cutting for agriculture, ranching and development, unsustainable logging for timber, and degradation due to climate change. This impacts people’s livelihoods and threatens a wide range of plant and animal species. Some 46-58 thousand square miles of forest are lost each year—equivalent to 36 football fields every minute.
Forests play a critical role in mitigating climate change because they act as a carbon sink—soaking up carbon dioxide that would otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns. Deforestation undermines this important carbon sink function. It is estimated that 15% of all greenhouse gas emissions are the result of deforestation.
Deforestation is a particular concern in tropical rainforests because these forests are home to much of the world’s biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching. Deforestation in this region is particularly rampant near more populated areas, roads and rivers, but even remote areas have been encroached upon when valuable mahogany, gold and oil are discovered.
WWF has been working to protect forests for more than 50 years. With a focus on protected areas management and sustainable forestry, WWF works with governments, companies, communities and other stakeholders to promote certification for responsible forest management practices, combat illegal logging, reform trade policies and protect forested areas.

Deforestation can happen quickly, such as when a fire sweeps through the landscape or the forest is clear-cut to make way for an oil palm plantation. It can also happen gradually as a result of ongoing forest degradation as temperatures rise due to climate change caused by human activity. While deforestation appears to be on the decline in some countries, it remains disturbingly high in others— including Brazil and Indonesia—and a grave threat to our world’s most valuable forests still remains.

Causes

Illegal Logging

National laws regulate the production and trade of timber products at all stages, from harvesting to processing to sales. These laws can be violated in any number of ways, such as taking wood from protected areas, harvesting more than is permitted and harvesting protected species. Illegal logging occurs around the world, and in some places, illegal logging is more common than the legal variety. This destruction threatens some of the world’s most famous and valuable forests, including rainforests in the Amazon, Congo Basin, Indonesia and the forests of the Russian Far East. Illegal logging also depresses the price of timber worldwide, disadvantaging law-abiding companies, and depriving governments of revenues normally generated by duties and taxes. Poor communities near forests are often vulnerable when outsiders try to gain control over the timber nearby, which can lead to repression and human rights violations.

Fires

Fires are a natural and beneficial element of many forest landscapes, but they are problematic when they occur in the wrong place, at the wrong frequency or at the wrong severity. Each year, millions of acres of forest around the world are destroyed or degraded by fire. The same amount is lost to logging and agriculture combined. Fire is often used as a way to clear land for other uses such as planting crops. These fires not only alter the structure and composition of forests, but they can open up forests to invasive species, threaten biological diversity, alter water cycles and soil fertility, and destroy the livelihoods of the people who live in and around the forests.

Fuelwood Harvesting

Wood is still a popular fuel choice for cooking and heating around the world, and about half of the illegal removal of timber from forests is thought to be for use as fuelwood.
