5 Causes of Deforestation

Look no further than your dinner plate, because between 2000-2018, agriculture was associated with around 90% of global deforestation. While this can mostly be attributed to meat production (particularly beef), large-scale soy and palm oil plantations follow closely behind as causes for deforestation.

But before you shun the tofu, let’s take a closer look: livestock farmers clear vast areas of forest to graze their livestock, and around 80% of all soybeans grown go directly to producing beef, chicken, eggs and dairy. And palm oil, a ingredient that’s nearly ubiquitous in processed foods, accounts for 7% of deforestation in above mentioned time period.

A staggering number of trees are cut every year to meet the incredible global demand for wood and wood products. From clear cuts to massive logging roads opening access to previously untouched areas, these deforested areas are much more vulnerable to conversion to other land uses like mining, agriculture, and settlement. And the issue isn't showing any signs of slowing down.

In fact, a 2023 study conducted by World Resources Institute and published in the journal Nature found that a projected 54% increase in global timber harvests to meet growing global demand for wood could produce more than 10% of total global carbon emissions over the next few decades

Thanks to an ever-increasing demand for minerals, mining affects up to 1/3 of global forest ecosystems (including indirect impacts). Mineral extraction has doubled since the turn of the century, increasingly impacting tropical rainforests and protected areas in places like the Amazon and Cerrado.

Overwhelmingly, mining-related deforestation can be attributed to just two commodities: gold and coal. Together, a recent study found that they resulted in approximately 6,877 square km of forest loss over the last two decades. Other minerals that significantly contribute to deforestation include bauxite, iron ore and copper.

And because large-scale mining is an intensive, industrial undertaking, it requires the development of significant infrastructure, which only increases ecosystem degradation.

As human population levels increase, forested areas get cleared to make way for the expansion of cities and settlements. Between 2001-2023, the World Resource Institute reported that approximately three million hectares of tree cover loss could be attributed to urbanization — or, the permanent conversion of forests into human settlements.

And with this urbanization comes even more land use changes to support the needs of growing communities. These include increased sprawl and building construction, waste management for household and industrial waste and sewage, laying of impervious surfaces for roads and highways, development of energy facilities such as power plants and electrical grids, and much more.

Climate change is a leading cause of deforestation. Extreme weather events like wildfires (which caused 138 million hectares of forest cover loss between 2001-2023), droughts, and storm surges destroy millions of hectares of forest every year — and their intensity is only increasing with global warming.

But the trouble doesn’t end there: after extreme weather events, deforested or degraded areas are highly susceptible to pests, diseases, and invasive species. This, in turn, can threaten healthy forests nearby.
