Answer:
The difference between afforestation and deforestation are summarized below:
Afforestation Deforestation
Afforestation is the planting of trees in a previously barren environment. Deforestation is the destruction of trees and forests for human habitation and use.
Afforestation has a beneficial effect on the environment. Deforestation has a detrimental effect on the environment.
The main reason for afforestation is to control carbon footprint and to ensure the sustainability of the natural environment. Deforestation is a result of industrialization, globalization and urbanization.
Afforestation can ensure balance and survival to all life on earth. Deforestation, if left unchecked leads to global warming, rising sea levels and encroachment or possible extinction of wildlife.

Explanation:
Afforestation
-Trees are planted near to the river. This means greater interception of rainwater and lower river discharge. This is a relatively low cost option, which enhances the environmental quality of the drainage basin.
-Afforestation cannot prevent flooding but it can help reduce its likelihood.
-Trees help reverse the greenhouse effect through the process of photosynthesis as they act as carbon sinks. In other words, establishing new forests create new carbon dioxide holding areas – reducing the carbon dioxide in the environment. The overall outcome is the reduction of the effect of global warming.
-Afforestation is a human-initiated plan, action or program of planting new trees.
deforestation
-Deforestation, clearance, clearcutting or clearing is the removal of a forest or stand of trees from land which is then converted to a non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests.
-Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing.
-Deforestation in tropical regions can also affect the way water vapor is produced over the canopy, which causes reduced rainfall. A 2019 study published in the journal Ecohydrology showed that parts of the Amazon rainforest that were converted to agricultural land had higher soil and air temperatures, which can exacerbate drought conditions. In comparison, forested land had rates of evapotranspiration that were about three times higher, adding more water vapor to the air.
-Commercial logging companies cut down trees for timber, which is mostly sold to developed countries. In most cases, large areas of forest are destroyed just to remove a few highly valued trees. The effect of this devastation has lasting consequences:
heavy machinery compacts soil and makes it more vulnerable to erosion
silt is washed into rivers
logging roads open up the area to new settlers who remove even more trees
-Land is cleared (eg by slash and burn) and planted with cash crops, usually just one - such as palm oil. Alternatively, it will be used for grazing by cattle ranchers. Most cash crops and cattle are eventually sold to developed countries.
These actions affect the soil for future use because fertility falls after just a few years. Only farmers who can afford fertilisers will be able to use the soil to grow crops in the future. If they can't afford fertilisers, farmers simply move on and clear more land, so more forest is lost.
-Land is completely deforested. Soil is often removed with high-pressure hoses and chemicals are used. The run-off goes into local rivers and pollutes them. Huge scars from open-cast pits are left - the soil can't recover.
