Question

How do reforestation and reclamation positively impact land?

Answer 1

Hint:
i) Reforestation is the process of replanting trees in an area, thereby regenerating the forest by replanting trees in areas that have been destroyed by humans for their own benefit.

ii) Forest land reclamation is the process of reclaiming formerly forested land in order to return it to a sustainable forestry use after mining. It is, in theory, a method of developing the best possible mine soil for trees and establishing a population of plant species that will grow into a healthy forest ecosystem without further human interference.

Complete answer:
Reforestation and reclamation positively impact land -
i) The aim of reforestation is to return a landscape to its natural state. This is also known as "rewilding," but the aim is the same: to restore an ecosystem or a landscape to its natural state before humans intervened.
ii) Restoration of natural ecosystems, which can protect against invasive species and benefit native wildlife, is one of the advantages. Soil erosion processes and soil health can return to normal, especially if an area transitions from a primarily urban to a vegetated environment. Since trees also act as carbon dioxide sinks, increasing their number mitigates some of the harm caused by humans' use of fossil fuels.
iii) Reduces carbon dioxide in the air: Reforestation raises the number of plants, which absorbs more carbon dioxide and enhances air quality.
iv) It thus increases the amount of rain and reduces the lack of water in order to improve the water cycle.
v) The production of plant products like gum, latex, fruits and plants, bamboo, etc. has increased.
vi) For instance, we may think it is appropriate to return a few blocks to the wild because we have a record of how this is the last natural landscape. Nevertheless, the area of land that has been a paved area/industrial area for the last 80 years may have actually advanced to a landscape more grassland if it had not been modified by humans.

Note: Natural climate solutions such as reforestation are cost-effective. Between 2020 and 2050, There is estimated that reforestation has removed 103 billion tonnes of carbon dioxide from the atmosphere since 2000. Increasing the rate of tropical reforestation would result in significant reductions in $CO_2$ emissions at a low cost.
