- Abstract:
- Food security is a complex and multi-dimensional phenomenon. As such, its measurement may entail and benefit from the combination of both 'qualitative-subjective' and 'quantitative-objective' indicators. Yet, the evidence on the external validity of subjective-type information is scarce, especially using representative household surveys. The aim of this paper is to compare information on self-perceived food consumption adequacy from the subjective modules of household surveys with standard quantitative indicators, namely calorie consumption, dietary diversity and anthropometry. Datasets from four countries are analysed: Albania, Indonesia, Madagascar and Nepal. Simple descriptive statistics, correlation coefficients, contingency tables and multivariate regression show that the 'subjective' indicator is at best poorly correlated with standard quantitative indicators. The paper concludes that while subjective food adequacy indicators may provide insight on the vulnerability dimension of food insecurity, they are too blunt an indicator for food insecurity targeting. An effort towards developing improved subjective food security modules that are contextually sensitive should go hand in hand with research into how to improve household survey data for food security measurement along other dimensions of the phenomenon, particularly calorie consumption.

- Abstract:
- India accounts for 16.7 per cent of the world's food consumers. With the exception of China, India's size in terms of food consumers is many times larger than the average size of the rest of the countries. At the time of independence in 1947, India was in the grip of a serious food crisis, which was accentuated by the partition of the country. The demand for food far exceeded supply, food prices were high and more than half of the population living below the poverty line with inadequate purchasing power. With high rates of population growth, the dependence on imported food increased further. However, the situation improved considerably after the mid-1960s, when new agricultural development strategy and food policies were adopted. The production of staple cereals increased substantially, mainly contributed by productivity improvements. The dependence on food imports decreased and the country became a marginal net exporter of cereals. There was also an improvement in physical and economic access of households to cereals and other nutritive food products. The proportion of households reporting hunger went down and the incidence of economic poverty reduced. This paper reviews the Indian approach to tackling the severe problem of food insecurity, which India faced immediately after independence. It reviews the evolution of food policy, the major policy instruments deployed, intervention in food marketing system, and the current status of food security/insecurity. The paper also identifies the lessons emerging from the experience of India. In developing countries characterized by large segments of the rural population dependent on food production for livelihood and by the high incidence of poverty, food insecurity and malnutrition, the strategy to improve food security must encompass programmes to increase food production that combine improved technology transfer, price support to food producers and supply of inputs at reasonable prices to farmers, improvements in food marketing system, employment generation, direct food assistance programmes, and improvement in the access to education and primary health care.

4. Food Security in Vietnam during the 1990s: The Empirical Evidence

- Abstract:
- Analysing the performance of ten developing countries, Hoddinot and Yohannes (2002) find a strong association between two measures of food security (calorie intake and mostly dietary diversity) and the increase in expenditures per capita. Using various indicators of food security, we describe the changes in food balances in Vietnam and find evidence of a substitution of poor micronutrients items (rice and cereals) with rich ones like fruit, vegetables fish and meat. Poor households, while increasing the amount of calories consumed, still lack vitamins, iron, calcium, etc. A preliminary assessment of the food security variation showed that improvements were, as expected, more concentrated among the richer Vietnamese households than the poor ones, although there was some improvement among poorer strata as well. We also focus on the calorie/expenditure elasticity and compare results for the years 1993 and 1998. Our findings confirm that this link is strong, and show that calorie income elasticity changed in the expected direction. We conclude that in general food security improved in Vietnam during 1990s although considerable differences still remain among expenditure deciles and among regions due to the accentuated spatial difference.

5. Longevity in Russia's Regions: Do Poverty and Low Public Health Spending Kill?

- Abstract:
- This paper examines the impact of changes in poverty and public health spending on inter-temporal variations in longevity using a unique regional-level dataset that covers 77 regions of Russia over the period 1994-2000. The dynamic panel data model is used as a tool for the empirical analysis. The model is estimated using the Arellano-Bond dynamic panel data estimator. The changes in regional levels of poverty and real per capita public health expenditure are identified to be significant determinants of the variations observed in longevity over time. The empirical results indicate that while male life expectancy responds more strongly than female life expectancy to economic circumstances, the latter appears to be more predisposed to the influence of public health spending. The results support the idea that the (positive) effect of public health spending on life expectancy is larger for those regions that experience higher incidences of poverty. The paper also finds that the financial crisis which hit Russia at the end of 1998 had a significant negative effect on longevity independently of the factors directly related to poverty and public health spending.

6. Illegal Immigration, Human Trafficking, and Organized Crime

- Abstract:
- It is important to make a careful distinction between illegal immigration, human smuggling, and human trafficking which are nested, but yet different concepts. This distinction is relevant because these different categories of the illegal movement of people across borders have quite different legal and political consequences. Human smuggling and trafficking have become a world-wide industry that 'employs' every year millions of people and leads to the annual turnover of billions of dollars. Many of the routes and enclaves used by the smugglers have become institutionalized; for instance, from Mexico and Central America to the United States, from West Asia through Greece and Turkey to Western Europe, and within East and Southeast Asia. More often than not flourishing smuggling routes are made possible by weak legislation, lax border controls, corrupted police officers, and the power of the organized crime. Naturally, poverty and warfare contribute to the rising tide of migration, both legal and illegal.
