Healthier soil - organic farmers use natural methods like composting to create healthy soil. Healthy soil acts like a sponge, soaking up water during floods and holding it for longer during droughts.
No polluting pesticides - hazardous synthetic pesticides need to be diluted to bring them to 'safe' levels when they enter waterways - over one fifth of water used to grow non-organic cotton is used for this purpose. This is not the case for organic cotton because hazardous synthetic pesticides are banned.
The way cotton is watered - most organic cotton is grown in rain-fed areas, this mean farmers rely on rain to water their cotton, instead of having to extract water from the ground which can put pressure on water supplies in local communities. The World Economic Forum has identified water scarcity as one of the top ten global risks to society over the next ten years, and the majority of cotton is grown in countries facing water shortages. Organic cotton uses significantly less water to grow than non-organic - up to 91% less.
To put this in perspective, it takes 2,700 litres of water to grow the cotton for just one T-shirt. By simply choosing an organic cotton t-shirt, you could save up to 2,457 litres of water, that’s enough drinking water for one person for three and a half years.
