The recent food crisis and slow progress towards the achievement of the Millennium Development Goal of eradicating hunger have highlighted the wide disparities in technologies used and productivity achieved in different agricultural systems. While input and resource-intensive agriculture is the norm in many developed and middle-income developing countries, many developing countries continue to rely on low-input, low-productivity agriculture. Even as the former group of countries need to shift towards less intensive and more environmentally sound methods, farmers in many developing countries would benefit from greater input use.
