Variabilidad climática estacional e interanual de la disposición final de residuos sólidos urbanos en Bogotá D.C., y su relación con la precipitación

Abstract

Monthly historical data on the final disposal of Urban Solid Waste (MSW) from the Doña Juana Landfill, in the city of Bogotá, D.C., for 19 years (1998 to 2016), and its relationship with precipitation were analyzed. Descriptive statistics were used. Within the seasonal climate variability, the MSW responded to the natural migration of the Intertropical Convergence Zone (ITCZ), thus, the maximum values ​​of MSW were deposited in the months of April (less rainy) and October (greater rainy). While, the minimum values ​​of MSW were in the months of January (dry major) and August (dry minor). In terms of interannual climatic variability, their behavior was given by the occurrence of one of the phases of the El Niño Southern Oscillation events. During the El Niño events (decrease in precipitation) an increase in the amount of MSW deposited was evidenced, while during La Niña events (increases in precipitation) the opposite occurred. It can be said that, in the management of MSW produced in the city of Bogotá, the dynamics associated with climatic periods must be taken into account in order to improve decision-making in this context.
