Importance of the Cachi Mayu and Cajamarca basins in Sucre: a review based on ecoregions, policies and environmental services

Abstract

With the appearance of man, the growing population, scientific and technological advance, social and economic expansion, a new sphere of the planetary ecosystem was formed. Although, the processes that develop within it and its interaction with the atmosphere, hydrosphere, lithosphere and biosphere play an important role in the dynamics of the current global ecosystem. In this context, the objective is to seek information about the components of the natural environment such as soil, water, lithology, geomorphology and fauna that function as a system permanently providing environmental services for society and local populations established in a certain territory; from a transdisciplinary perspective. In this case, with respect to the Cachi Mayu River basin and the Punilla River sub-basin of Cajamarca identified with the free-use QGIS 3.28.3 software. The scarce information was evident regarding updated multi-temporal studies of flora and fauna, land use, actions on the integrated management of basins at the level of the Ravelo, Potolo, Maragua-Cachi Mayu and Cajamarca sub-basins in the upper part due to their importance in the provision of water for the city of Sucre and in the lower part of Maragua-Cachi Mayu for its diverse uses in the area. There are weaknesses in effective policies, plans and programs in the integrated management of basins and in the comprehensive management of water resources.
