is many desert regions water is diverted from streams and rivers to people in cities how does this affect the animals in the area​

When such a criterion takes place, the animals move closer to cities in search of food and water.

Explanation:

When food and water become scarce in any area, the animals tend to migrate from one place to a place where they can find food and water. The animal moves to the cities as there are climatic changes taking place. Some animals move due to unsuitable habitats, and some to survive.

So, in the given scenario, when water streams of a desert region are diverted to the cities, the animals of the desert region move to the cities in search of food and water.
