Analysis of Food Self-Sufficiency in Corn in the Papaloapan Region, Oaxaca, Mexico

The Papaloapan region of the state of Oaxaca, Mexico is an important producer of grains, mainly corn, production is carried out in two spring-summer and autumnwinter sowing cycles, allocating an annual surface of 62,000 hectares with a production of 176,857 tons and an average yield of 2.8 t ha-1.Given the need to move towards selfsufficiency in food production, mainly corn, a study was carried out with the purpose of analyzing the current production and consumption situation and determining the deficits or surpluses in production and how far the food self-sufficiency in the region.For this, official statistical sources were consulted and consumption estimates were made for both the population and livestock, taking into account the main species in the region and the Food Self-Sufficiency Index (IDA) was calculated.The results indicated that the region is self-sufficient in the production of corn for human consumption, although there are very deficient municipalities such as Tuxtepec and Loma Bonita, local production manages to supply the demand of the urban and rural centers of the region; However, when animal consumption was considered, the region became deficient, so to cover the total need for grain it is necessary to increase yields to more than 5.0 t ha-1, almost double what is currently obtained, so The importance of increasing the productivity of this grain is highlighted, which is part of the goals of the Technical Support Strategy of the Production for Well-being Program.
