The availability of food in Mexico: an approach to measuring food security

Abstract

Abstract Background information Mexico faces a great challenge in producing, storing, and distributing food to guarantee the food security of its population. Natural disasters, climate change and changes in land cover are dynamic drivers affecting food production. In this study, we propose a method for assessing food security by evaluating the amount of food in Mexico that is available to meet the demand of its population. An indicator of food availability based on environmental, social, production and food supply variables is proposed. Methods Food availability in Mexico's 2471 municipalities was assessed using five sub-indicators covering environmental and social conditions of production, food supply, caloric and protein sufficiency, and food supply. A database of 19 variables was integrated to calculate an index of food availability by municipality. Spatial analysis techniques were used to identify areas with specific needs and to formulate public policy recommendations. Results The availability of food is not a problem at all in 90% of the municipalities in the country. We found that the environmental and social conditions are suitable for producing food from agriculture and livestock and there are sufficient food outlets. The caloric demand and protein requirements of the population can be met in at least 87% of the municipalities. Thus, the environmental and social conditions are good in more than 85% of the municipalities. If food production and availability are sufficient; then, the problem of food insecurity may be due to other causes. Conclusions and recommendations The conclusion is that food insecurity in Mexico is influenced by additional factors. An urgent intervention is needed, including public policies to provide economic support to the most affected segments of the population.
