ABSTRACT
The world’s food system is directly responsible for about a quarter of the world’s greenhouse gases (GHGs), and contributes to much more as the major driver of deforestation. However, in many countries it is also likely to be negatively affected by climate change, and many countries thus affected already suffer from food insecurity which could be made worse. An astonishing proportion of food that is grown is not eaten. It is either lost because of inadequate infrastructure in developing countries to get it to market, or, in richer countries, it is bought and then thrown away. The world’s food system needs to be transformed by introducing more sustainable agricultural methods, eating less meat in countries where the level of its consumption is bad for health, and reducing food loss and waste. None of the measures needed to achieve these outcomes are likely to be easy to introduce.
