The dilemmas inherent in cultivating the soil, producing crops, and raising livestock go beyond the current food crisis. They are about the livelihoods of farmers -- and consumers­ everywhere; about crops and soil, land rights and indigenous peoples, gender, and rural landscape and culture; about animals, biofuels, GMOs, pesticides and fertilisers; about environment and organic production; about trade barriers, corporate farms and subsidies. They are about sustainability. IPS explores this complex topic in our coverage on agriculture.
