Since the mid-2000s agricultural and food prices moved to a higher level and in parallel with prices of other commodities – and at times have also been very volatile. These events led to concerns which, in different ways, brought to the forefront a debate about food security. Both developed and developing countries saw their consumers facing the impact of higher food prices, and their producers feeling the pressure from higher input costs. In a series of Briefs (on Demand, Regional influences, Supply and Stocks) we analyse evolutions in different drivers responsible for these price developments separately and bring them together in a concluding Brief.
