100% organic is pie in the sky, especially considering the strict approach of registered organic systems. However, a significant proportion of UK' farmland will need to be farmed using organic-based systems and by this I mean:
- significantly less pesticides of the type used now (new ones may have been produced using GM techniques)
- significantly less artificial P or N
- integrated arable/livestock with composted waste used to maintain fertility (compost being the key point, not slurry of non-composted sludge etc) - the compost will be vital for maintenance of fertility through the work of soil mycorhhizae*
*healthy soil biodiversity is fundamental to effective nutrient cycling; mycorrhizae can mobilise P from mineral soil as well as other elements; this area seems to be missing off the radar of the farming industry at present. Note that mycorrhizae are destroyed through applications of artificial fertilisers and some non composted waste as well as pesticides used against fungi and probably other pests).
Farm machinery will also have to be operated using electricity/batteries as diesel will become prohibitively expensive.
The potential for reversing the exodus of working rural population should also be seen as an opportunity. There are now 2.5 million unemployed. Could we consider questioning the current orthodoxy (bigger farms, bigger machinery, fewer farmers, more farmer suicides/loneliness, few/monoculture crops, specialisation, lack of rural housing) and putting more people back living and working in the countryside. What is the point of fossil-fuel-energy intensive farming if it can't produce as much food as may, for example, some agroforestry models? (And moreover by continuing as we are we make people effectively homeless, contribute to unemployment, ill health and thus increase the cost in supporting them on benefits). We could also grow a lot of different food crops that we don't grow now. (e.g. why don't we grow more pulses for human consumption - fodder beans grown for cows are actually quite tasty!)
A debate on land reform is needed and should be considered part of a package for increasing the resilience of people and farming against future pressures from climate change and all the rest. For instance, when farms are sold, to offer them for community buyouts, as happens in Scotland? And look at enabling good quality rural cohousing and community landshare schemes to happen (this would in many ways reinvent farming 'families' - and make the people side of farming more sustainable in the long term). Community supported agriculture is I believe something which should grow in the UK - it has barely started as yet, but there are a few examples (e.g. River Bourne Community Farm www.riverbournecommunityfarm.org.uk and the Hosking farm in Shropshire)
Personally, I think that the farming industry and policy makers are continuing to follow an orthodoxy on farming which may not be valid in the long term for many reasons whether it be an ageing and declining farming population, unsustainable fossil-fuel based practices, environmental damage (e.g. metaldeyde in water) and continuing biodiversity loss.
Finally, we have to stop the speculation on land, and consider whether support should be permitted for horse-keeping where the horses are not working or being used to maintain land of biodiversity value. These is at their worse around the urban fringe. 1.3 million horses in England use a lot of land which some would say should be (a) better managed and (b) used to grow food.
Colin Tudge and others have I believe some useful contributions to this debate, which needs to be mainstreamed.( See www.peoplelandfood.com and go to the Oxford Real Farming Conference next year. )
I say we all need to WAKE UP to the huge problems that affect society and for which sustainable farming in the future could help to resolve. This means opening our minds to new models of farming that may be very difference, in some places, to what happens now.
