Diseño hidrológico de un sistema VAC para la finca el Caimo ubicada en el municipio de Villa de Leyva, Boyacá

Abstract

His article proposes to improve the productivity of the agro-ecosystem of the El Caimo farm located in the municipality of Villa de Leyva, Boyacá, by rehabilitating its agricultural production system; implementing an integrated agricultural system of cultivation that is part of the Basic Manual of Integrated Agro-Aquaculture of the United Nations Food and Agriculture Organization (FAO), being the VAC system of North Vietnam, which integrates the elements that are part of its structure looking for its operation and synergy taking into account the combination of the elements and their distribution in space, added to changes in the current coverage (land use) of the El Caimo farm. This is based on the elaboration of a hydrological design, with the aim of interpreting and quantifying through mathematical models the natural processes immersed in the hydrological dynamics that intervene in the productive development of the El Caimo estate, and in parallel the elaboration of a digital elevation model (DEM) through Geographical Information Systems (GIS) for the consultation of data and hydrometeorological information and the representation of georeferenced data for its analysis through a software to find behaviour patterns of different variables, for the delimitation of the hydrographic basin near the farm, with the purpose of identifying strategic points for the natural capture of precipitation water and its discharge by runoff directed to the natural supply of the components of the VAC system, as these are interactions between the climate and land systems. This is applicable to the agricultural production system of the El Caimo farm, which is developed in the management of an agro-ecosystem that requires the availability of resources for its operation, including water availability and its use, since it is a complex socioeconomic system, limited and determined by the social and political system in which it is located; by the value that the economy assigns to the farm’s resources and products; by the lack of road infrastructure, labor, capital, technology, and information that allows or limits the integration of the components that the farm offers, and that together contribute to the development of the production process. This situation explains its low productivity, which is a consequence of the lack of implementation of good agricultural practices. In this way, a 4% decrease in the run-off potential of the El Caimo farm is obtained
