FAQ: Why Did Farmers Need To Develop A System To Control Water Supply?

Why did farmers need to develop a system to control their water?

Farmers needed to control their water supply because they can either have too much water or too little. Another reason is because they needed to provide dams to control flooding when rivers overflowed when things thawed in the spring, or during heavy rain fall, and to be able to have water during a drought.

What happens if farmers run out of water?

Water scarcity is a top risk to global food production. Estimates call for a need to double the production of food by 2050, but water scarcity might spur a future food crisis because smallholder farmers, who are especially at risk, produce a significant share of the world’s food.

Why do farmers need water?

Water is essential for all life on the farm. Farmers obtain most of the water for their crops from rain. Rain water that is not absorbed by the soil and plant roots runs into streams and rivers. Farmers in areas where there is not enough rain for their crops to grow must irrigate their fields.

How can farmers use less water?

Various techniques farmers may consider include conservation tillage, using compost and utilizing cover for crops. Again, what works the best to conserve water will depend on what kind of soil is being managed. Avoiding or mitigating runoff can save millions of gallons of water over the course of a growing season.

How much water will there be in 2050?

This number will increase from 33 to 58% to 4.8 to 5.7 billion by 2050.

Will we run out of freshwater?
