Abstract: diet and caloric sufficiency in the migrant indigenous population of the altos region of chiapas, méxico. the population that has migrated from rural zones to urban areas is subject to changes in their dietary patterns and is considered a vulnerable population group in terms of food security. this article describes the diet of the immigrant indigenous population in the city of san cristóbal de las casas, analyzing the factors that contribute to adequate calorie consumption in 143 families. this is a cross-sectional study based on a structured interview in which information was obtained related to socio-economic variables, the variety and types of foods in the home, and adequate calorie consumption per capita based on requirements according to age and sex. using nonparametric statistical tests, the relationship between the population?s income level and the number of calories available was determined. results show a significant association between the income level of the population and the number of calories available in homes; however, there is not a significant association between the amount of time a family has lived in the city and the type and variety of foods available to and consumed by these families. results show that 91.3% of these families ingest the suggested calorie consumption; the population with the lowest income levels represents a lower percentage of this indicator, and also showed significant deficiencies in proteins and nutrients such as calcium and vitamin a. the implications of rural-urban migration by indigenous populations in relation to diet quality are discussed
Kp Pan Evaporation and ETo Monthly Maps Using Information of 60 Weather Observatories Included in the Climate Normals (1941-1970) from Mexico  [PDF]

Abstract: The most precise equation in order to estimate the evapotranspiration (ET) of crops is the Penman-Monteith (PM). However, the PM equation needs specific data that, in the majority of Mexico’s irrigation districts, it is not available because there are few automated weather stations. For this reason, it is convenient to develop simple methods that allow to precise estimation of ET. A reliable way to estimate ET is by using the pan evaporation that, according to the revised literature, continues to be used nowadays. Investigators like to include its use in irrigation water management projects in various parts of the world. However, this method uses Kp from the FAO that is not calibrated in Mexico. The use of FAO Kp affects the precision of the results, since some variables like radiation, wind, temperature and relative humidity vary from place to place; therefore ET is under estimated or overestimated. This paper presents an original contribution across method to estimate “Kp pan evaporation and ETo monthly maps”, using information from 60 weather observatories included in The Climate Normals (1941-1970) from Mexico, based on the PM method and the class A pan evaporation. Once the Kp values were obtained from each weather observatory, the Kringing method was used. This way, by interpolating data of the triad “latitude, longitude and Kp” and “latitude, longitude and ET”, monthly normalized maps of Kp and ET were established for Mexico, except the upland areas (Sierra Madre Occidental and Sierra Madre Oriental), as well as other highland zones above 2700 meters over sea level, for the highest observatory is located in Toluca, State of Mexico (key 14-0039), at 2680 m over sea level.
