Answer:

When discussing drought, one must have an understanding of aridity and the difference between the two. Aridity is defined, in meteorology and climatology, as "the degree to which a climate lacks effective, life-promoting moisture" (Glossary of Meteorology, American Meteorological Society). Drought is "a period of abnormally dry weather sufficiently long enough to cause a serious hydrological imbalance". Aridity is measured by comparing long-term average water supply (precipitation) to long-term average water demand (evapotranspiration). If demand is greater than supply, on average, then the climate is arid. Drought refers to the moisture balance that happens on a month-to-month (or more frequent) basis. If the water supply is less than water demand for a given month, then that month is abnormally dry; if there is a serious hydrological impact, then a drought is occurring that month. Aridity is permanent, while drought is temporary.

a. Vulnerable groups such as migrants, fishers, small-scale farmers, children who are dependent on school meals, sick individuals with special food needs.

b. Developing countries and underdeveloped countries. Small island developing countries are also at risk because they depend on the importation  of food.

This is the horizontal movement of air caused by heating from the sun and rotation of the planet.
Illusion [34]

The answer is;  Wind

They drive atmospheric circulation. The sun does not heat the earth evenly. The parts that are heated up more form the low-pressure systems where air masses move in from high-pressure systems to form winds. These air masses are also deflected by Coriolis effect caused by earth’s rotation.
