How does deforestation lead to reduced rainfall 8?
Trees and Plants absorb water from earth through the roots. This water goes back into the atmosphere through transpiration(evaporation of water through leaves). If plants and trees are cut, then less water will evaporate in the atmosphere, which leads to reduced rainfall.
Why does local rainfall decline with deforestation?
This drop occurs because deforestation reduces the natural recycling of moisture from soils, through vegetation, and into the atmosphere, from where it returns as rainfall. They combined this with satellite data on precipitation to determine whether the air’s increased exposure to vegetation had an effect on rainfall.
Does deforestation cause less precipitation?
That’s because air passing over forests picks up moisture given off by trees and plants, fueling rains. When those trees disappear, so does some of that rain. Deforestation can reduce rainfall over a wide region, even as it spurs increased rainfall in the immediate area where that deforestation took place.
What led to deforestation?
Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Most often, multiple processes work simultaneously or sequentially to cause deforestation.
How does deforestation reduce rainfall on the one hand and lead to flooding on the other?
The increase in temperature on the earth disturbs the water-cycle and reduces rainfall. So, the movement of water from the soil surface into the ground is reduced which brings the flood.So,deforestation reduce rainfall on the one hand and lead to floods on the other.
How does deforestation lead to flood?
Note: Deforestation leads to frequent floods and droughts. It happens because the soil loses its fertility over time and also water holding capacity of the soil gets reduced. In the presence of trees, the soil has a high water-holding capacity and it reduces the risk of floods in the heavy rainfall.
What is the effect of deforestation on rainfall and climate?
Answer: Deforestation causes increases in temperatures and changes in the amount and distribution of rainfall —generally creating a drier climate. These impacts can affect soil moisture, reducing yields in some areas and increasing flooding in others.
