the need to grow more using less
The world's population is growing - to support this, we need to grow more, using less, whilst mitigating and adapting to climate change
Agriculture uses 69% of abstracted water globally today - and the UN forecast this to increase to 89% by 2050.
20% of agricultural land is irrigated - and produces 40% of global food. Not every crop and not every soil is suitable for irrigation, but 35% of land would benefit. This would produce 120% of todays food production, but use 89% of abstracted water.
Some forms of irrigation are less efficient than others, and this technology encourages better irrigation practices. Even if we bought all irrigation to modern standards, we'd only be at 125% of today's food production and 79% water use.
We'll need direct re-use from wastewater treatment works to plug the gap.
That's where we come in: by recovering low carbon nutrients in liquid form, produced all year round, we encourage more smart irrigation and greenhouse growing - so we promote the more efficient use of both water and nutrients in agriculture.
By converting potash to sulphate of potash, we improve the crop's resilience to climate change. How important is that going to be?
When we look into the need for more drinking water, direct re-use from a wastewater treatment plant using this process, with concentration of the products to fit with tractor boom sprayers, opens up the market to all types of agriculture
Let's also look at this where you have a subsistence agricultural community with a single well - this can help increase the community's resilience
