  • USDA’s Economic Research Service (ERS) projects that average per capita food consumption for 67 low-income countries will increase in the next decade. ERS also projects that the number of people failing to meet their nutritional requirements will decline from 774 million in 2000 to 694 million in 2010, providing an improved outlook for global food security. But the gains are not uniform across countries and in many food insecurity will probably intensify.

  • There are many causes of food insecurity, among them macro and micro issues, the roots of which are essentially internal or indirectly caused by relationships with other countries. Examples are political instability, poor economic governance, poverty and a lack of sustainable household income. The issue of HIV/AIDS has added another critical dimension to the search for food security.

  • Food availability, access, stability and utilization are all part of the multi-dimensional nature of food security. The “availability” aspect, discussed here, refers to the availability of sufficient quantities of food of appropriate quality, supplied through domestic production or inputs. Productivity is usually considered the ultimate benchmark when comparing the performance of agricultural systems. For example, those involved in agricultural research and development want to know how much yield would be reduced if conventional agriculture were converted to organic agriculture.

  • Contemporary interest in food is not confined to pleasure in its consumption, but extends in every direction: to its economic importance, the semiotics of food taste, the dangers of food additives and the politics of food security. We live in societies as dominated by food preferences as by sexual preferences, as obsessed about eating too little as by eating too much. In addition our interest in food is associated, for good and evil, with our interest in ‘nature’.

  • The United States is viewed by the world as a country with plenty of food, yet not all households in America are food secure, meaning access at all times to enough food for an active, healthy life. A proportion of the population experiences food insecurity at some time in a given year because of food deprivation and lack of access to food due to economic resource constraints. Still, food insecurity in the United States is not of the same intensity as in some developing countries.

  • Viet Nam’s success in achieving rapid agricultural growth since the implementation of policy reforms in the late 1980s is now well documented (World Bank 2004). Agri-cultural growth was fueled mainly by growth in rice productivity following the rapid adoption of modern varieties, increased fertilizer use, and increased cropping intensity.

  • This book has its conceptual origin from the lecture materials of the training courses taught by one of the authors in the early nineties. It was during this period that in several developing nations, particularly in Africa, even when the signs of widespread hunger and abject poverty were visible, policy makers did not act for want of ‘empirical evidence’. Some policy makers even dismissed the severity of the problem saying that the hunger reports prepared by government officials were not rigorous enough to take them seriously.

  • The new century has begun with some of the lowest grain prices in recent memory. From an economist’s vantage point, this is a sure sign of excess production capacity. However, there may be more here than meets the economist’s eye. Natural scientists, many of whom have contributed to this volume, see something very different. They see reason to be concerned about such issues as the overplowing of land and the overpumping of aquifers. They look at sustainable production and see a worrisome fraction of world food output being produced with the unsustainable use of land and water....

  • Unlike natural disasters, where any disruption to business service provision is likely to be hardware-related, disruption to business operation in the event of a pandemic is anticipated to be mainly human-resource oriented. Individual employers must consider their workforces and their particular circumstances. However, most should plan for up to 50% staff absences for periods of about two weeks at the height of a severe pandemic wave, and lower levels of staff absence for a few weeks either side of the peak. Overall, a pandemic wave may last about 8 weeks.
