French farmers and their sheep took over the Paris commodities exchange to protest against too much speculation. Activists also took to the streets to protest against biofuels and the volatility of food prices. The French police detained at least four sheep. Noone was injured in the protest.

This week in Paris, the G20 Agriculture Ministers met for the first time ever, to address the global food price volatility crisis. At the meeting, the G20 Agriculture Ministers agreed on a plan to collect more data on the food crisis.

UN has warned that the world is on the verge of another hunger crisis. Activists are calling for global leadership to stop subsidies of biofuels as too much food is being used to fuel cars and not to feed people. Smallholder farmers - who produce most of the food consumed in the world - need to get credit and fair prices. Food is also too expensive because of market speculation on commodities.

In the past year food prices have doubled and an additional 80 million people at now risk from hunger - this is in addition to the 900 million who are already poor and going hungry.

For activists this is just the beginning of a long campaign pushing for action. The question remains - what will be done to prevent another food crisis?

The follow up G20 Agriculture Ministers meeting will take place in Cannes, November 2011.
