There are serious challenges to global food supply everywhere we look. Intensive use of fertilisers in the US Midwest is causing nutrients to run off into rivers and streams, degrading the water quality and causing a Connecticut-size dead zone in the Gulf of Mexico. Chocolate production will soon be challenged in West Africa – home to over half of global production. A variety of nutritional impacts are predicted due to increased atmospheric carbon dioxide – including decreased protein content in food, which has a potential to exacerbate malnutrition. And this is just a very small sample of the risks to the food supply chain that are foreseen.

The future of food then, may sound rather bleak. But this does not have to be the case. The food system could become part of the solution for environmental challenges, if we make some changes to it. It could also be an instrument of human health, well-being, dignity, and livelihood – rather than the opposite. Read the rest of this entry »

Industrial agriculture – farming that involves the intensive production of livestock, poultry, fish and crops – is one of the most environmentally destructive forms of land use. It depends on mechanisation and on inputs like synthetic fertiliser and harmful pesticides and herbicides and has led to widespread contamination of soil and water. It also relies on just a few major crops like wheat, maize, soybean and rice, the seeds of which are owned by a mere handful of companies.

A different approach to agriculture is sorely needed. This should, ideally, deliver household food security, ensure sustainable livelihoods and produce quality nutrition in a rapidly changing climate.

Developing countries that are industrialising at a pace are uniquely placed to avoid developing a dependency on one type of technological innovation at the expense of others. This is what is known as technological lock-in, with industrial agriculture being one form of lock-in. Such countries are also well placed to establish alternative ways to grow food that maximise livelihoods and sustainable food production. Read the rest of this entry »
