Food security concepts and issues

Lessons from the IPCC SREX Report, the effects will include changing productivity and livelihood patterns, economic losses, and effects on infrastructure, markets and food security.

Local Food Systems: Concepts, Impacts, and Issues

That is, there is now ample theoretical, conceptual, ethnographic, and quantitative work done to justify the measurement of the experience of food insecurity using a questionnaire.

Even a decade ago, there were about definitions in published writings [22]. Governments in most countries give priority to urban areas, since that is where the most influential and powerful families and enterprises are usually located.

The current measure of prevalence of household food insecurity obtained through the HFSSM focuses on the uncertainty and insufficiency of food availability and access that are limited by resource constraints, and the worry or anxiety and hunger that may result from it.

Pillars of food security[ edit ] Growth in food production has been greater than population growth. Furthermore, there is no evidence to suggest that the original decision made when the measure was developed to focus on food insecurity that arises in the context of economic constraints—deemed to be the food insecurity that is policy-relevent—should be altered.

Linking hunger and sub-nutrition with inadequate food intake allows the measurement of food insecurity in terms of the availability and apparent consumption of staple foods or energy intake [33].

Where the focus of investigation is on sub-nutrition, then the linkages between sub-nutrition and inadequate food intake need to be carefully explored.

These problems were recognized as the result of lack of effective demand. Although the phrase "Food Security" is being used widely, the definition and concept of food security is elusive and being evolved and expanded over time. Linking hunger and sub-nutrition with inadequate food intake allows the measurement of food insecurity in terms of the availability and apparent consumption of staple foods or energy intake [33].

The panel therefore concludes that hunger is a concept distinct from food insecurity, which is an indicator and possible consequence of food insecurity, that can be useful in characterizing severity of food insecurity.

Food access is another dimension of food security which encompasses income, expenditure and buying capacity of households or individuals.

Food and Human Security. This concept is closely related to the human rights perspective on development that has, in turn, influenced discussions about food security. Households often make trade-offs among needs to ensure their long-term viability as units.

Before accepting that comfortable conclusion, it is appropriate to re-examine the issue of transitory food insecurity and the possible links with liberalization. The Plan of Action set a number of targets for government and non-governmental organizations for achieving food security, at the individual, household, national, regional and global levels.

As temperatures rise due to climate change there is a risk of a diminished food supply due to heat damage. This chapter discusses the conceptual issues associated with the concepts and definitions of food insecurity and hunger and their applications for measurement in the monitoring of food insecurity in the United States.

The chapter also discusses the labeling of the severity levels of food insecurity.
