MARTINEZ-JIMENEZ, Alejandro; GARCIA-SALAZAR, José A.  e  MORA-FLORES, José S.. Warehouse capacity and maize (Zea mays L.) storage demand in the state of Chiapas, Mexico. Agrociencia [online]. 2015, vol.49, n.6, pp.669-702. ISSN 2521-9766.

The seasonality of maize production (Zea mays L.) in the state of Chiapas, Mexico, and the uniformity of consumption during the year determine temporary excess supply that cause a decrease in prices for producers. A storage policy could avoid the problem of excess supply, but its implementation is not possible if the installed capacity of warehouses is insufficient. With the objective of determining whether the infrastructure of warehouses allows satisfying the storage demand required for an inventory program, the solution to a spatial and inter-temporal equilibrium model was found for the maize market in Chiapas in the year 2012. Only in the regions of La Frailesca and Isthmus-Coast the capacity installed is greater than the storage demand. The demand excesses for maximum storage in the Center and Border regions are 143 and 94 thousand Mg in February, and the Highlands, North and Soconusco regions present 10 months with maximum amounts in February and July. Storage is necessary for an adequate management of production in time and investing in warehouses in regions where excess supply causes a fall in prices would be necessary.
