Every March 22, World Water Day reminds us of the vital importance of freshwater despite it being far smaller in volume than our planet’s huge reservoir of saltwater. Water is essential to the life of every organism, but the effects of climate change on this resource are already visible, so we need to adapt our use of it.
Large quantities of water are used to support crop growth around the world, with the aim of guaranteeing sufficient yields to feed an ever-growing global population.
Difficulties maintaining sufficient yields
Changes in rainfall patterns and declining reserves are restricting access to water resources, while rising global temperatures are affecting plant evapotranspiration. In other words, plants are forced to absorb more and more water to maintain their growth… at a time when this resource is becoming increasingly scarce.
This directly links to the crucial issue of securing global food supply. 50% of the world’s calorie production is based on four essential crops: cereals, rice, corn and soy, all of which require water.
