Answer 2

Answer:

Irrigation is the man made resource.

Explanation:

The agricultural practise of applying measured amounts ofwater to land to help in crop production, as well as to develop landscape plants and lawns, where it may be referred as watering, is known as irrigation. 

• Rain-fed agriculture is defined as agriculture that does not use irrigation and relies solely on direct rainfall. 
• Irrigation is the artificial application of water to the soil through various systems of tubes, pumps, and sprays. 
• Irrigation is usually used in areas where rainfall is irregular or dry times or drought is expected. 
• There are many different kinds of irrigation systems, where water is distributed evenly across the entire field. 

Without irrigation, agriculture could not be sustained in areas with infrequent or irregular rainfall.
