IMPACTS OF THE HAZARD ON THE ENVIRONMENT, ECONOMY, AND PEOPLE.
Droughts have an impact on the environment, the economy, and people.
Impact on the environment;
Droughts can often cause wildfires, dust storms, pests such as locusts. Many animals die from lack of water, or become dehydrated.
Impact on the economy;
Bad effect on food production. When there isn't enough water for crops on a farm, there isn't enough food for the country, let alone enough for the countries the food was going to be exported to. A heavy loss is made. In addition to the crops, there wont be enough for livestock, and this would lead to even heavier losses.
Impact on the people;
People often have less water to use, have a limit of how much water they can consume, set by the government. People often get dehydrated if they live in a place where there is a drought.

GEOGRAPHICAL PROCESSES RESPONSIBLE FOR DROUGHTS.
There are many geographical processes associated with droughts.
Some of these processes are:
Southern Oscillation;
A Southern Oscillation is a major pressure shift which occurs between the Asian and East Pacific regions. An extreme form of Southern Oscillation is El Nino. El Nino is a current which results in extremely dry conditions and lack of rainfall.
Global Warming;
Many people argue that human-induced global warming effects have contributed to the severity of droughts.
Rainfall;
A drought is a long period without rain, and when there is a lack of rainfall, droughts occur.
Evaporation;
The sun's heat evaporates all the moisture in the atmosphere, thus making it drier, and less chance of rainfall occurring, which leads to droughts.
Latitude;
A change in mid-latitude (60 degrees) depression tracks. These are related to weather changes, such as extreme dry weather.
