In 2015, the United Nations predicted that the world population will grow to 9.6bn by 2050 and 70% of the population will live in cities.
However, such a population increase comes hand in hand with the need to produce more food to feed them. Some estimates suggest 70% more food will be needed. But with 80% of cultivated land already in use and the rapid urbanisation of countries set to continue, the challenge of producing more food in a sustainable way will become ever more pressing.
One solution is hydroponic technology, a niche method of food production that allows producers to grow plants without soil. A subset of hydroculture, this method uses mineral nutrient solutions to feed plants in water without the need for soil.
Climate change has made the growing of food risky. This is because you cannot predict the timing or severity of its occurrence. Hydroponics is the answer to this. When there is too much water because of a sudden storm or too little water because of drought, hydroponics conducted in the safety of a greenhouse can produce the highest quality product.
