Explain why many would have an increased difficulty in collecting water during a water shortage.
It was difficult because people have to queue up to to collect water during the water rationing exercise.
Crop yield decreases with decreased water supply. It became difficult to produce enough food to feed the people.
It became difficult because water became very scarce and people had to travel long distances in search of water to obtain them.
Prices of water will increase with water becoming scarce. Production costs will increase and costs of goods will increase too.
