Each year, the world loses around 5 million hectares of forest, with 95% of this deforestation occurring in tropical regions. South America is a major hotspot, with Brazil in particular facing severe forest loss — much of it driven by cattle ranching, which accounts for more than 70% of all Amazon deforestation.

Many of these clearings are carried out by farmers, particularly smallholders, who are trying to cope with intensifying drought and other effects of climate change. This leads to a paradox: the people most exposed to climate threats are often pushed by survival pressures to make choices that further degrade the environment.

Imagine standing in a field of dry, cracked soil, watching the crops you planted with hope fail to grow. It hasn’t rained in months. You know that planting trees could help protect your land and water sources in the long run. But you need food next week.

So instead, you clear some forest to sell timber and raise a few cows — a choice that might get you through the season, even if it further reduces soil moisture and water retention on your own farm.
