On Wednesday 12th July I’ll be giving in a talk in Hereford, 7.30 at De Koffie Pot, on the subject “Can we feed 9 billion people, sustainably?” My answer to that is an emphatic “YES!” with a few big if’s and buts. We live in a world where the old problems of hunger and famine persist and where a global obesity epidemic is emerging. Providing an optimal diet for the 7.5 billion of us alive today, or the projected 9 billion of us who’ll be sharing the planet by 2050, seems to me theoretically achievable but will require change in many ways. Many of the changes required are not to do with farming systems but with social and economic systems. Bringing peace, stability, democracy, development and probably some kind of basic income schemes to the poorest countries will be necessary to conquer the old problems of hunger and famine. Changes to education, taxation and other social measures will be required to address obesity.
Change also needs to come to farming systems, many of which are leading to soil erosion and water pollution and which are in any case often economically dependent on grant support which is unlikely to continue. I’ll be showing slides and talking about at least half a dozen very different farming systems that seem to me to offer hope. They are an incredibly diverse bunch. Some very high tech, some very low tech. Some building soil fertility and in the process sequestering atmospheric carbon, others, like hydroponics, by-passing soil altogether.
I’ve blogged before about Sundrop farms pioneering farm at Port Augusta in South Australia. They use solar power to desalinate sea water, and to provide electricity, heating and cooling for the greenhouses in which they grow huge crops of tomatoes hydroponically. Turning hot dry deserts into centres of sustainable food production seems to me to be one of the greatest opportunities to increase global food production.
The best systems of pasture management can restore damaged and degraded soils and sequester carbon while producing excellent quality meat and dairy products while improving animal welfare. Such systems are promoted by the Pasture Fed Livestock Association and one of my favourites is White Oak Pastures in Bluffton, Georgia, USA. There is a great 14 min video with Will Harris talking about his farms transition. The resulting ecological and economic regeneration of the area has been hugely impressive.
A very different path is being pioneered by Iain Tolhurst in south Oxfordshire in England. Tolhurst Organics was the first farm to achieve the Soil Association’s Stockfree Organic symbol. They have pioneered building soil fertility with green manures and composting without any animal manure, so making the farm a beacon for those wanting a sustainable and vegan system of food production.
These are just a few of the examples I’ll be talking about at De Koffie Pot. If you’re in Hereford area then do come along and join in the discussion. You may know of farms that are doing great work, and if so I’d love to hear from you.
