To avoid the footpaths which may have been mined with improvised explosive devices (IEDs), Ryan Evans, a U.S. federal civilian, was walking across a wheat field in Babaji, Helmand Province, in the spring of 2011.

Begun 2 years earlier, the Helmand Food Zone Program was a form of development intervention which offered subsidies, seed, and fertilizers to farmers who replaced lucrative opium cultivation from poppies with growing and harvesting wheat and vegetable crops. Babaji had been in the control of insurgents until a few months earlier and had not received any assistance from the program during the previous year; consequently, there were tensions between the community and British forces. As Evans and the patrol emerged from the field, an Afghan man sitting nearby, clearly irate, shouted in Pashto that the British soldiers had wanted the farmer to grow wheat instead of poppy, and then the same British soldiers walked through their fields. At the immediate level, the encounter demonstrated the direct link between conflict, food security, and local trade, but conflict has many interrelated and mutual dependencies such that the anecdote is instructive on myriad broader milieus.
