Hans Rudolf Herren (born November 30, 1947)[1] is a Swiss American entomologist, farmer and development specialist.

He was involved in the preparations of the United Nations' Rio+20 Conference on Sustainable Development with Biovision Foundation and Millennium Institute.

[1] Herren then developed a number of other biological control programmes against field and tree crops as well as aquatic weeds across sub-Saharan Africa.

Since 2005 he heads the Washington-based Millennium Institute, dedicated to system dynamics modeling for scenario-based sustainable development policy support.

According to Herren: "Today's GMOs don't produce more food, they help cut production costs - in the first few years until insects and weeds catch up again - as we have seen earlier with the use of insecticides.

The report suggests that business as usual is not an option and recommends a number of action in research and implementation that address the food and nutrition security now and for the decades ahead.
