Guest Lecture by James Adkins

In oct 2nd, Mr. James Adkins lectured our class about the importance of irrigation in today’s agriculture. Agriculture is all about water, crops cannot survive without water. Therefore, water efficiency is a big concern, especially in the places where are lack of water. There are only 20% of the world’s farmland is irrigated, in the meantime it produces 40% of food supply. Asia has the biggest percentage of irrigation about 68%. In India, 90% of its freshwater is used for agriculture and it cause approximately one‐fifth of the nation’s total electricity consumption. Crops need water, the amount of water used by 100 acres of corn in one day during pollination is 1 million gallons and it equal to the total water use of 10 households in a year. And it is unsustainable. It is pretty a shocking news for me. I have been heard so many appeals like, saving water, remember to close water tap. But compared to agriculture, citizens daily water consumption is not the significant problem of world’s fresh water shortage. It is really a critical issue for agriculture to solve. The improvement in irrigation technology do have advantage for this problem.
