Guest Lecture: Irrigation

On October 2nd, James Adkins came to our class to discuss irrigation and its importance. Only 20% of the world’s farmland is irrigated and 40% of that provides our food. Asia has the largest percentage of irrigated land at 68%. India uses 90% of its freshwater  withdrawals for agriculture while China uses 65% of its freshwater withdrawals for agriculture. 

From state to state irrigation and water rights change. For example, the cost of California’s water is likely to be more expensive than the water we have in the east coast. California has more drought than us and so they are more likely to have higher prices for water. 

With new technologies, we changed our irrigation systems. We developed aluminum pipes after World War II because we have a lot of aluminum left over from the war. The extra materials were put to good use. Then came the center pivot. The center pivot is easy to use and it provides an even distribution of water across all the crops. 

Irrigation is an important part of our agriculture system, so it is best to have the highest quality equipment that provides the most payoff.
