Sand dunes are very helpful in coastal management. Destruction or destabilization of sand dunes will make us it hard to survive from storms and destruction of some vegetation also.
What is sand dunes?Shorelines and desert landscapes frequently have sand dunes. Highly specialized plants and animals, especially rare and endangered species, find habitat on dunes.
Sand dunes offer essential ecological habitat as well as natural coastal defense against storm surge and strong waves, preventing or minimizing coastal flooding and structural damage. They serve as sand storage sites as well, delivering sand to beaches that have degraded.
Human activity, both purposeful and unintentional, endangers dunes Significant dune protection projects are run by nations like the United States, Australia, Canada, New Zealand, the United Kingdom, and the Netherlands.

What are solar radiations?Solar radiation can be described as electromagnetic waves coming from the sun and comes in three major types: visible light, infrared light, and ultraviolet light.
The electromagnetic spectrum has seven different types of light, listed from lowest frequency to highest: radio waves, microwaves, IR light, visible light, UV light, X-rays, and gamma rays. Solar radiation is light from the sun that can be categorized by its frequency and wavelength.
Solar irradiance can be described as the power per unit area received from the Sun in the form of radiation in the wavelength range and is measured in watts per square meter.
This may be measured in space or at the surface of the earth after atmospheric absorption and scattering. The forests have plants and trees which absorb the most solar radiation.
