To explain why ending hunger has been so hard, Peter Timmer highlights four main themes: the complex role of markets, the importance of government policies, the historical process of structural transformation, and the need to identify the appropriate time horizon for analysis and interventions. These themes are not new, but integrating them into a coherent approach to ending hunger seems to be original
Even as Congress was mandating large increases in the consumption of biofuels a decade ago, the world was changing. In the early 2000s, replacing fossil fuels with biofuels made from corn, sugar, or oilseeds seemed like a good idea. Increased crop demand would prop up prices for farmers, and replacing petroleum with renewable energy would reduce greenhouse gas (GHG) emissions and promote energy independence.
Trade is a key tool to bring food security to an estimated 800 million people around the world that remain chronically undernourished. Many countries need reliable access to international markets to supplement their inadequate domestic food supplies. Better policies to make agriculture in developing countries more productive and profitable, including via exports, would also help alleviate food insecurity and reduce poverty. Stronger international trade rules would help by constraining the beggar-thy-neighbor policies that distort trade, contribute to price volatility, and discourage investments in developing-country agriculture.
The discovery of antibiotics in the early 20th Century was a major breakthrough for human health, markedly reducing the infection threat from minor cuts, surgery, and cancer treatment.
Food security has arisen again on the development agenda. High and volatile food prices took a toll in 2007–08, and in many low-income countries agricultural yields have risen little, if at all, in the last decade. Moreover, food production in these poor countries is especially vulnerable to climate change. Meeting this demand is a global challenge. The Food and Agriculture Organization of the United Nations (FAO) is expected to lead the way in meeting this challenge and, with the arrival in 2012 of the first new director-general in 18 years, it has an opening to restructure itself to do so.
