how does deforestation contribute to flooding?
358329
Deforestation plays several roles in the flooding equation because trees prevent sediment runoff and forests hold and use more water than farms or grasslands. ... Tree roots absorb water from the soil, making the soil drier and able to store more rainwater.

The loss of trees, which anchor the soil with their roots, causes widespread erosion throughout the tropics. ... After heavy tropical rains fall on cleared forest lands, the run-off carries soil into local creeks and rivers. The rivers carry the eroded soils downstream, causing significant problems.

Of course yes. Deforestation is a human activity in order to fulfill their needs. The actual disasters are the aftereffects of deforestation. Deforestation is done for the purpose of making the land available for many other needs such as agriculture, construction works etc.

Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils. ... The major impacts on marine environments can be sedimentation and turbidity; litter and human-built waste deposited from the land; toxins, nutrients and mineral deposition.

Deforestation. Without plant cover, erosion can occur and sweep the land into rivers. The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion.

Wildfires alone, not the fires deliberately set for deforestation, can pump out billions of tons of carbon dioxide during drought years, recent research found. Amazon deforestation rates had been tumbling for years, largely thanks to the “Save the Rain Forest” movement and stronger land-use regulations.

The loss of trees, which anchor the soil with their roots, causes widespread erosion throughout the tropics. Only a minority of areas have good soils, which after clearing are quickly washed away by the heavy rains. ... The rivers carry the eroded soils downstream, causing significant problems.

Floods or flashfloods are commonly cause by human interference in the environment. ... On the latter part, floods (if too much) can cause landslides, which in turn may cause devastation, loss of human lives, and destruction of properties such as buildings and crops.

Soil erosion due to Deforestation: Tree roots anchor the soil. Without trees, the soil is free to wash or blow away, which can lead to vegetation growth problems. The WWF states that scientists estimate that a third of the world's arable land has been lost to deforestation since 1960.

Deforestation has a direct link to soil erosion. And like fingers, they grip the soil they penetrate. This makes the soil immune to getting washed away during rains, heavy winds or floods. Forests actively prevent soil erosion, which has been considered the biggest caused of land degradation.

Because trees release water vapor into the atmosphere, fewer trees means less rain, which disrupts the water table (or groundwater level). A lowered water table can be devastating for farmers who can't keep crops alive in such dry soil [source: USA Today]. On the other hand, deforestation can also cause flooding.

Trees remove CO2 from the atmosphere when they photosynthesise, so without them less CO2 is removed. So deforestation means more CO2 in the atmosphere which leads to global warming. ... Without trees, the water isn't removed from the soil and evaporated into the atmosphere.

Major and immediate impacts of climate change include increased flooding, storms, drought, and food insecurity. The world's climate depends on the Amazon's rain forests. ... When Amazon rain forests are lost, less water is released into the atmosphere, and fewer clouds form which can promote droughts.

When forests burn, there is less moisture released into the atmosphere, which can mean less rainfall. ''There could be impacts to the rainfall patterns as far away as the U.S.,” Cesareo says.

When forests are replaced by pasture or crops, it can reduce the amount of evapotranspiration (ET) – the recycling of moisture back into the atmosphere by leaves. So the air that has travelled over deforested areas is less humid, which one might expect would lead to lower rainfall.

is deforestation necessary for development, yes of course the deforestation increases then the economical system will be damaged and the forests will be cut down. also you know, the deforestation is the main reason for global warming . ... Deforestation is a two-sided gamble, as are your arguments.

Farmers, for example, typically drained swamps next to their fields so as to gain more land usable for planting crops. In reality, swamps play an important ecological role in our environment and provide a variety of resources that we depend on. Swamps and other wetlands are used as a tool in flood management.
