Globalisation is causing dramatic changes that are transforming agriculture in developing countries away from supply driven production towards market-driven 'agrifood' business. The impact of these changes on people, economies and the natural environment is, and will continue to be, profound. An immediate impact has been that world commodity prices have fallen to their lowest levels for 35 years. Understanding and being able to respond to such change is vital for the livelihoods of millions of smallholder farmers in developing countries.
