How does deforestation affect groundwater?

Deforestation significantly decreases groundwater recharge, which is the process where water from precipitation filters through the soil and replenishes aquifers. Trees and vegetation play a critical role in this process. They not only facilitate the absorption of rainwater through their roots but also help to maintain soil structure. Their presence prevents soil erosion and allows for a more efficient infiltration of water into the ground.

When forests are cleared, the soil often becomes compacted due to the absence of vegetation, leading to a decrease in its permeability. This means that less rainwater can penetrate the ground and replenish the groundwater supply. Additionally, without trees to provide shade, evaporation rates can increase, further reducing the amount of water that reaches the aquifers.

In summary, the removal of trees disrupts the natural water cycle, leading to diminished groundwater recharge, which can have dire consequences for water availability in the surrounding area. This is critical to understand in discussions about environmental management and the importance of forest ecosystems.
