Agriculture

Globally, the agricultural sector consumes about 70% of the planet’s accessible freshwater. Because water is vital for the success of agriculture, proper water management techniques are necessary to meet food and fiber material demands around the world. Resources available here pay special attention to efficient irrigation and sustainable agriculture techniques.
