Agriculture accounts for the vast majority of the water use worldwide, a significant portion of which occurs in the form of irrigation. While this water use plays a vital role in producing food and other goods, there is also great potential to use less water while improving yields. Such efficiency measures can help ensure that enough food can be grown for all and that sufficient water is also available for other community, industrial, and ecosystem uses. Agricultural device technologies, such as drip irrigation, can significantly improve agricultural water use efficiency at the farm level, improve yields, and reduce chemical runoff. Modern technologies can also assist farmers in monitoring weather forecasts; gathering crop data; and measuring soil moisture, temperature, and water pH levels. In fact, growers can achieve great improvements in efficiency simply by changing the timing of their irrigation to coincide with low evaporation rates. By approaching this issue collectively, growers can help their peers understand the business case for efficiency, get access to the needed resources and technology that drive results on-the-ground, and unlock their knowledge of additional beneficial approaches.
