As we consider a world of 7 billion and counting, the same two questions are coming up over and over again – how will we ever have enough water? And how on earth can we feed that many people?
The issue of food is a controversial one – everyone has an opinion. They’re widely divergent opinions too – from those who believe that Big Ag and genetic modification is the solution to billions of hungry mouths, to those who promote an aggressively local and small-scale farming system as the only way to stave off global hunger.
Unsurprisingly, I’m not in that group of folk who think that GM and monoculture cropping are going to save the world. In fact, a future like that seems very bleak and dystopian to me – the idea of a handful of companies essentially owning our food and thus our bodies is abhorrent to me. Local and small-scale is wonderful, but not always realistic on its own – every city would have its challenges in producing clean and healthy food, other regions lack the fertility of soil and availability of good weather conditions to be able to fully sustain their populations. It’s a good start though, especially when it incorporates the principles of agroecology.
But what is agroecology? The word hasn’t yet acquired that buzz-word status, like ‘local’ or ‘organic’ (and, thankfully, hasn’t been diluted into a fuzzy meaninglessness like those words). And while agroecology can be seen as a relatively recent reaction to the shortfalls of industrial agriculture, it is based on farming techniques that are often hundreds of years old. Essentially, agroecology is a movement towards more sustainable farming methods, based on ‘time proven farming methods, new ecological science, and local farmer knowledge’ (McAfee in Cohn et al 2006). UC Santa Cruz’s Center for Agroecology & Sustainable Food Systems describes it as the development of ‘sustainable food and agricultural systems that are environmentally sound, economically viable, socially responsible, nonexploitative, and that serve as a foundation for future generations.’
Agroecology is therefore the antithesis of Big Ag. That sounds pretty appealing, for sure. But does it work?
Yes. Plus, it kind of has to. The 2013 Trade and Environment Review from the UN Commission on Trade and Development concluded that major changes in agriculture are necessary, recommending a ‘rapid and significant shift from conventional, monoculture-based and high-external-input-dependent industrial production toward mosaics of sustainable, regenerative production systems that also considerably improve the productivity of small-scale farmers.’ Our current systems are not resilient (monoculture cropping is by its nature more vulnerable than polycultures), nor are they sustainable – the extensive requirements for chemical fertilisers, herbicides and pesticides contributes to degradation of soil, of water supplies and climate change. Business as usual will end up business-as-it-used-to-be.
Agroecology has the potential to stop this damage to our agricultural systems and ensure a lesser environmental impact in three ways:
1) A variety of crops are usually planted on each farm, rather than monocultures. This also reduces the need for chemical pesticides and herbicides.
2) Crop biodiversity is preserved. As discussed earlier, in situ conservation is vital to the preservation of the wide variety of maize landraces
3) Less land is required to produce a similar amount of food, thus posing less of a threat to the local environment
We need to make a change and agroecology has a small but positive track record – at the very least, running more trials, replicating these on a large scale and thus collecting more evidence of its efficacy is worth a shot, as it may well provide us with a solution to an eventual crisis.
