This book is about food security as a global perspective. The drastic rise in food prices over the past couple of years has raised serious concerns about food and nutrition security across the world. While a coordinated response is urgently needed at international and regional levels, the effectiveness of country level response is critical for responding to the crisis. Coherent action is needed to help vulnerable populations cope with the hikes in their food bills, to assist developing-country farmers to swiftly respond to the opportunity posed by the rising demand for their products, and to provide information for evidence based related macro-economic policies. Since the implications of high and volatile food prices have been radically different across countries and population groups, the appropriate policy responses, as well as their scale, prioritization, and sequencing, must be developed and adapted to country-specific needs and conditions.
