SOCIAL Sky Greens can bolster food security in urban areas like Singapore, where the vast majority of food is imported.

THE TRIPLE BOTTOM LINE

ENVIRONMENTAL According to the company, this closed-looped irrigation design results in zero agricultural run-off and eliminates risk of contamination to land and water sources.

Using a patented hydraulic and closed-loop irrigation system, rows of planting trays are rotated on towering frames up to three stories high. This approach enables intensive cultivation as significantly increases labor and land productivity, as it requires no arable land. The ability to grow food independent of the quality of land available also contributes to food security. Due to its irrigation system, Sky Greens reports that its precision farming is capable of functioning on less than 5% of the water and as little as 25% of the fertilizer and pesticides needed in traditional open field farms. Furthermore, its hydraulic technology also means that very little electricity is required, with one tower requiring around 40 watts per hour, or the equivalent of a small incandescent light bulb. WHY A SUSTAINIA100 SOLUTION? The World Health Organization estimates that 70% of the global population will be residing in urban areas by 2050.1 In the face of this growing pressure, the farmland on which global food production depends is degrading rapidly. Consequently, sustainable food production is a pressing
