Determinación de los impactos en el protocolo IGAC para la evaluación del efecto en el cambio de uso sobre las propiedades del suelo y los servicios ecosistémicos en el complejo de páramos altiplano cundiboyacense.

Abstract

Paramo’s ecosystem has a significant role as a hydro regulator and due to its soil characteristics, it can be affected if the land use presents changes or variations.

The present work will focus on evaluating the effect on how the different types of grounds or lands change, taking into account a few soil properties that can be evaluated in one of the most complex CAR jurisdiction paramos such as the Altiplano Cundiboyacense, located at the north of the Cundinamarca Department, part of the Chocontá, Villapinzon, Lenguazaque, Suesca, and Cucunubá township sectors. How the soil is impacted because of the ground use was determined by the use or validation of the protocol that the Agustin Codazzi geographic institute elaborated for the CAR (Corporación Autónoma de Cundinamarca), being one of the main results of the “ Multi-temporal study of ground/land uses, mantles and soil liftings taking a 1:10.000 scale as a reference in the CAR jurisdiction paramos zones” A general overview of the importance of paramos in Colombia was included in the present evaluation, verifying the different background records, conceptual, normative, and methodological frameworks, developing the correct methodology applied to the soil use changes impact evaluation upon the paramos soils properties, more specifically in the locations or places in which changes have been occurred. Soil use changes will be identified by carrying out a comprehensive multi-temporal study of mantles and soil uses between 2011 and 2019, aiming to present the soil use change's evidence impacts. The soil quality, relative soil degradation, and absolute degradation indexes (SQI, RSDI, ASDI) were generated, along with the ecosystem services lost in order to evaluate the paramos conservation and depletion/degradation through the soil properties such as: Bulk density, usable moisture or humidity, porosity, soil organic coal, total databases, voluble aluminum, and phosphorus saturation. The election of the properties mentioned above was taken as they represent properties highly sensitive to degradation by continuous land use.
