Evaluating the Impact of the Food Support Program (Programa de Apoyo Alimentaria)

Evaluating the Impact of the Programa de Apoyo Alimentaria

The Programa de Apoyo Alimentaria (PAL) started in 2003 and is targeted to communities in Mexico that do not receive benefits from other federal food aid programs, have less than 2,500 inhabitants and a high level of marginalization. Marginalization is a term used in Mexico for the multidimensional assessment of poverty in a community.

When the program started in 2003 it provided beneficiary households either a cash transfer of 150 Mexican pesos (equivalent to approximately 14 USD at the time) per month or a monthly food basket with a cost to the program of 150 pesos. The size of the cash transfer and the amount of food was the same for all households, i.e. no adjustments for family size or composition were made. The basket contained a number of staple and basic food products and powdered whole milk (Liconsa), which is fortified with Zn, Fe, Vitamin C, and folate (Table 1). The composition of the food basket conformed to the Mexican norm for food aid programs (NOM-169-SSA1-1998), which states that food transfers need to provide at least 20% of the recommended daily energy and protein requirements. Beneficiary households were required to attend nutrition and health education sessions and had to participate in program related logistic activities in order to receive the benefits. These program conditionalities, however, were not strictly enforced.

A community randomized controlled intervention trial was used to evaluate the impact of the intervention. A random sample of 208 rural communities was drawn from the pool of eligible communities in 8 of the poorest states in the South/Eastern region of Mexico (Chiapas, Guerrero, Oaxaca, Quintana Roo, Tabasco, Campeche, Yucatan and Veracruz). Within each community a random sample of 33 households was selected. The baseline survey was conducted from October 2003 to April 2004. After baseline data collection, the 208 selected communities (6,687 households) randomly assigned to one of four study groups: food basket without education (52 communities, 1657 households), food basket with education (52 communities, 1680 households), cash transfer with education (53 communities, 1687 communities) or control (51 communities, 1663 households). Treatment allocation was carried out by the Ministry of Social Development.

Inclusion Criteria:

• Live in a community that does not receive benefits from other federal food aid programs, have less than 2,500 inhabitants and a high level of marginalization. Marginalization is a term used in Mexico for the multidimensional assessment of poverty in a community. It takes into account housing quality (including the percent of households without piped water, without sewage and without electricity), income (proportion of household below two times the minimum wage), education (including illiteracy) and urbanization.
• Households within these communities were eligible if they fell below the "needs" poverty line as defined by the Mexican Ministry of Social Development. This corresponds to an income level sufficient to cover basic needs in food consumption, health and education.
