The rice was grown in a field near the Yellow Sea coastal city of Qingdao in China’s eastern Shandong province. 200 different types of the grain were planted to investigate which would grow best in salty conditions.  Sea water was pumped into the fields, diluted and then channelled into the rice paddies.

That leaves less than 1% of the planet’s water easily accessible in rivers, lakes or aquifers. In short, the salinity of the oceans means useful water is scarce, while the less useful kind is abundant. So why is the sea...
