Drought

Some ways of explaining how to help drought conditions are:

We are trying to "relieve drought".
We want to "aid drought victims".
We need to "assist countries who need help".
We should try to "alleviate the problems caused by water shortages".

The words relieve, aid and assist are all words that mean "to help". They can be used in other contexts of helping out in emergency situations too.

- Our school collected money to assist the fire victims.

- I gave a donation to aid the victims of flooding in Central America.

The word "alleviate" means to lessen the effects of something like pain, drought, suffering, etc.

- You take aspirin to alleviate the pain of a headache.
