Afforestation leads to erosion control, stabilization of the water cycle and, like agricultural and livestock primary and secondary production, wealth creation which fosters the accessibility aspect of food security.

The good news is that trees and forests have an important role to play in preventing the loss of topsoil through soil erosion. They reduce the amount of water in soil through transpiration. Their roots bind soil to sloping ground. They break the wind, preventing it from blowing soil away.

The large canopies of many trees help to prevent soil erosion by reducing the impact of rain onto the ground. The water drains down the leaves and branches and soaks into the soil rather than forcefully hitting the ground, which decreases the amount of soil that is washed away with the rain.

Afforestation helps to address all the issues of soil erosion and barren land at the same time. Trees act as wind barriers thereby weakening the speed of the wind and reducing its impact and ability to carry big soil particles.

If not properly managed, afforestation can result in a reduction of local biodiversity, the modification of particular biomes, the introduction of non-native and potentially invasive species, reduced stream flow, and lost revenue from agriculture.

An underappreciated problem is that biophysical consequences of afforestation can negate climate effects of reducing CO2 [6]. Forests absorb more incoming radiation than grasslands so that plantations may cause a net warming, rather than the intended cooling.

Afforestation projects have the potential to contribute to negative emissions (carbon removal), since the growth of additional plant sequesters atmospheric CO2 and naturally sink it in their biomass and in the soil.

More advantages of afforestation are: Afforestation also increases water resources for agricultural activities. It helps to improve the quality of air. Afforestation helps to deal with global warming. Trees help to maintain a proper balance between oxygen and carbon dioxide in the atmosphere.

Afforestation involves the planting of trees in a drainage basin to increase interception and storage while reducing surface run off. This reduces a river’s discharge and so makes it less likely to flood.

Some of the common techniques used for flood control are the installation of rock beams, rock rip-raps, sand bags, maintenance of normal slopes with vegetation or application of soil cements on steeper slopes and construction or expansion of drainage. Other methods include dykes, dams, retention basins or detention.

Deforestation has also increased the risk of flooding indirectly. When trees are removed from the planet, so too, is their capacity to take in carbon dioxide. Deforestation is a very real contributor to global warming – and, by proxy, it is a contributor to rising water levels and increased flooding.

Human activities that degrade the environment often increases flooding. These activities include: Deforestation. The lack of vegetation encourages water to flow over the surface rather than infiltrate into the soil thus increasing surface runoff.

But clear-cutting forests, aka deforestation, makes flooding worse. The Why Files explains again: “In terms of flooding, the unimpeded raindrop impact on bare ground leads to heavy erosion and quick runoff.” Without trees to soak up water, lessen rain’s impact, and hold soil in place, rain runs faster off land.

Deforestation plays several roles in the flooding equation because trees prevent sediment runoff and forests hold and use more water than farms or grasslands. Some rainwater stays on the leaves, and it may evaporate directly to the air (the more water used in the watershed, the less remains to run off).

Due to deforestation, the water holding capacity of the soil decreases. The roots of the trees get dried after they’re cut down. The movement of water through trees into the soil slows down. The water of the rainfall collects on the surface which results in flood.

3)More National Parks and Sanctuaries should be built throughout the country to protect the natural environments of wild animals and birds. 4) The Department of Government should conduct a wildlife conservation survey in all forests on a regular basis.

The use of fossil fuels is the primary source of CO2 emissions, but the removal of trees from forested land has also contributed. Mature forests, having absorbed CO2 from the atmosphere while growing, store carbon in wood, leaves, and soil. That carbon is released when people clear forested land and destroy the wood.

Tropical deforestation contributes about 20% of annual global greenhouse gas (GHG) emissions, and reducing it will be necessary to avoid dangerous climate change.

Global warming is an aspect of climate change, referring to the long-term rise of the planet’s temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.
