The Impact of the Global Food Crisis on Self-Assessed Food Security
Has the rise in international food prices since the mid 2000s hurt the poor, or helped them? Until recently, everything we knew about this topic came from simulation analyses rather than survey data. Simulation approaches invariably predict that poverty and food insecurity increases as the result of higher food prices, but there are many reasons why these predictions might not eventuate. On the other hand, standard household surveys yield information only after long lag periods. In light of these constraints, in some of my work I use an indicator of self-assessed food security from the Gallup World Poll (GWP). Since 2005, Gallup has survey men and women in a large number of developing countries and asked them (among other things) whether they have had “any trouble affording sufficient food in the last 12 months?” I take the percentage of respondents who answer yes to this question as a measure of national food insecurity.

Today the world seems to hold its breath again amidst the sudden hike in food prices caused by a historical drought in the US and lack of rain in Eastern Europe.
While the world’s population doubled in the last fifty years, global food production trebled – especially in the staple grains that form the mainstay of the poor man’s diet. Yet, over a billion people in the world still go hungry - why?
Three years from the deadline for reaching the Millennium Development Goals, two-thirds of countries will not reach MDGs 4 and 5 (child and maternal mortality, respectively). And now the second food price rise in three years is a wake-up call for the development community.
Food prices are finally coming down after a year of spikes and high volatility. But we must remain vigilant. Prices of certain foods remain very high, and millions of people around the world are still at risk of suffering from malnutrition and hunger.
including for biofuel production in Europe and the United States. They are also due to supply-side factors, such as higher energy prices which impact transportation and fertilizer costs, and weak harvests in large exporting countries.
Global food prices remain high and volatile, affecting the poorest countries the most. Global prices might not be at their 2008 record high, but they are still well above their levels a year ago. For millions who are already vulnerable, events like the droughts in the Horn of Africa add to their hardships while continued market turmoil increases uncertainty in the global economy.
How are communities around the world coping with the higher and more volatile food prices? What is the impact on poverty, or on nutritional outcomes? And, how should policymakers respond to such price spikes that can eat away at already-tight budgetary resources?
Turmoil is not solely circumscribed to Wall Street and stock markets around the world. Volatility is also affecting global food prices, and with them, millions of people in developing countries. So, just as the world marks the birth of the 7 billionth baby this week, his or her family might be struggling to put food on the table.
