Political will is needed for food and climate policy to be better integrated to address future challenges.
There are encouraging signs that this is already happening with more countries committing to public investment in agriculture and new initiatives, including the World Bank’s proposal to link agriculture-related investments with the transition to climate-smart growth.
While I welcome such endeavours, I do think more can be done now in terms of making the food chain more efficient. The Foresight report makes clear that waste in all areas of the food system must be minimised as much as 30% of all food grown worldwide may be lost or wasted before and after it reaches the consumer.
The report calculates that an amount of food equivalent to about a quarter of today’s annual production could potentially be saved by 2050 if the current level of global food waste is halved.
In middle to low-income countries, where infrastructure for storage and supply is often inadequate, there needs to be a better deployment of existing knowledge and technology in storage and transport infrastructure and investment in new, appropriate technology to reduce post-harvest waste.
There are not many straightforward answers, reducing waste is one of them, but it will not be easy.
