Rising food prices can prompt political and urban unrest. The potential for that is elevated in Kinshasa, the continent's third largest city.
It turns out the internet is a fascinating place for people looking for information on food prices. The Food and Agricultural Organization (FAO) has some great price tracking tools here that allow you to make your own charts out of different commodities.
I have pasted several different charts below to give you an idea of food price developments in the Congo and their possible political importance. In the first chart, I compare cassava flour – probably the most important, cheapest staple in much of the country – in Kinshasa, Kisangani, Bunia and Lubumbashi. Two observations: Kinshasa is much more susceptible to fluctuations in the food markets, even the local one (all cassava flour is sourced locally), due to its reliance on the hinterlands for food. So an increase in fuel prices and bottlenecks in supply will affect this behemoth of a city much more than places like Bunia, where there is plentiful local production. (See corresponding chart here.)
My second observation on this chart is that, while cassava prices have risen gradually, increasing by 15 percent to 35 percent, they are still below their crazy peak in 2008- 2009 during the financial crisis. (We also need to be a bit careful about this price index, as it is expressed in Congolese francs, which have seen 10 percent to 20 percent inflation over the past two years – some of the economy is still dollarized, which provides a bit of a buffer to inflation in local francs).
