Helena Cotler
Im a a Agronomist Sciences PhD from Gembloux School (Belgium). My interests are soil conservation, watershed integrity and public policy.
I have a special interest in conducting research and directing theses that can contribute to changes, working with social and governmental organizations.
I am researcher at the Centro de Investigación en Geografía y Geomática "Jorge L. Tamayo" A.C. and professor at the National Autonomous University of Mexico.

to address this issue through a study of Chapultepec Park in Mexico City. We provide two methodological proposals for the analysis of soil ecosystem services characterized by the interaction of natural and anthropic processes: the morpho-pedological landscapes (MpL),
in which we quantify soil carbon sequestration (SOC Mg ha−1) and the comparison of two methods for the analysis of hydraulic conductivity: Pedotransfer functions (PTF) and direct measurement with a double ring infiltrometer. Among the 12 MpL, we found the highest SOC content in slopes with mixed tree vegetation and Phaeozem soils. However, SOC
retention decreased by 40%–50%due to sealing surfaces. For infiltration measures, despite the diversity of soils and vegetation, direct measurements values are highly homogeneous, while values calculated using PTFs better reflect the morphopedological landscape
heterogeneity. In all the MpLs, the hydraulic conductivity was higher than the maximum rainfall intensity report, indicating that the soils in Chapultepec Park, despite the differences in soils and intensity of use, provide the ecosystem service of infiltration. These results would
allowthe establishment of a baseline formonitoring these services and provide information to decision makers and urban planners seeking to reduce the construction of gray infrastructure that seals soils and reduces their capacity to provide these ecosystem services.
