Question

Plantation of trees on a large scale to check soil erosion called _________________.
A. Shelterbelts
B. Contour ploughing
C. Strip cropping
D. Afforestation

Answer 1

Hint: It is the way toward acquainting trees and tree seedlings with a territory that has beforehand not been forested. Afforestation should be possible through tree planting and cultivating, normally or misleadingly.

Complete answer: Afforestation is the foundation of woodland or remains of trees (forestation) in a zone where there was no past tree cover. Numerous administration and non-legislative associations straightforwardly take part in projects of afforestation to make woods, increment carbon catch. Some of the time unique instruments, for example, a tree planting bar, are utilized to make the planting of trees simpler and quicker. The pace of net backwoods shortfall diminished considerably over the period 1990–2020 because of a decrease in deforestation in certain nations, in addition to increments in the woodland region in others through afforestation and the normal development of timberlands. In certain spots, timberlands need assistance to restore themselves on account of natural variables. For instance, in dry zones, when the woodland cover is annihilated, the land may get dry and ungracious for the development of new trees. Different variables incorporate overgrazing by animals, particularly creatures, for example, goats, bovines, and over-reaping of wood assets. Together these may prompt desertification and the deficiency of dirt; without soil, backwoods can't develop until the long cycle of soil creation has been finished - if disintegration permits this. In some tropical zones, timberland cover expulsion may bring about a duricrust or duripan that adequately close the dirt to water infiltration and root development. In numerous regions, reforestation is unthinkable because individuals are utilizing the land. In different territories, the mechanical separating of duripans or duricrusts is vital, cautious, and kept watering might be basic, and exceptional assurance, for example, fencing, might be required.

Thus, option (D) is correct.

Note: A few new examinations recommend that woods draw in the downpour and this may clarify why the dry spell is happening all the more habitually in pieces of the world, for example, western Africa.
