The grand political narratives around the COP21 conference in Paris will barely touch on one crucial aspect – food. The Paris talks are of vital importance, not just for climate change itself but for framing what kind of food economy follows. And why does food matter for climate change? Well, it’s a major factor driving it yet barely gets a mention.
From growing food to processing and packaging it, from transporting to selling it, cooking it, eating it and throwing it away – the whole chain contributes significantly to greenhouse gas emissions. Livestock alone makes up 14.5% of all anthropogenic greenhouse gas emissions. And agriculture emissions have increased rapidly in the last decade, as global diets and tastes change. Deforestation and forest degradation (often because of agricultural expansion) cause an estimated 17% of global greenhouse gas emissions.
People used to argue that this was a regrettable cost of progress. But most analysts now think differently, reminding us that the current food system is failing many. Almost 800m people in the world are hungry, at least two billion are not getting enough nutrients, and 1.9 billon adults are overweight or obese (39% of all adults over 18 years of age). Meanwhile, a third of all food produced globally is lost or wasted.
