Rainwater is normally free from dangerous substances, which makes it perfect for irrigation schemes. Added significant benefit is that it decreases the requirement for fresh water. It is important particularly in regions with low water levels. 
Another benefit might water harvesting have in these areas with land erosion due to runoff are as follows;
Reduces Water Shortages
In temperate areas, the strain on public water supply can become hard, even in advanced countries. Rainwater decreases the uncertainty of water shortages. Using rainwater for non-essential actions such as spraying the lawn means less pressure on the supply of safe drinking water. 
Replenishes Groundwater
Extensive rainwater harvesting projects with the water collected into storage containers or tanks are important to assure a sustainable groundwater level.
Reduces soil erosion
Heavy rainfall generates erosion because some of the soil is transferred along with the passage of water. Soil erosion exhausts agricultural land of topsoil and nutrients, provides to sediment build up in waterways and, in advanced cases, can turn land inadequate for agriculture. Harvesting rain checks a great chance of soil erosion before it can originate.
 
        
             
        
        
        
The production of these crops is centered in the eastern third of the state but there are notable concentrations elsewhere, particularly in the river valleys of the Arkansas River (central Arkansas) and the Red River (southwest Arkansas).
 
        
             
        
        
        
Answer:
The correct answer is B. Myopia is also known as nearsightedness.
Explanation:
Myopia is a refractive defect of the eye in which parallel light rays converge at a focal point located in front of the retina, instead of converging on the same retina; it is the inverse defect to farsightedness, in which the light rays reach the retina before converging.
A person with myopia has difficulty focusing well on distant objects, which causes visual acuity deficits and can also lead to headaches, strabismus, visual discomfort and eye irritation.
