Análisis del espaciotemporal de la huella hídrica del arroz en el departamento del Meta

Abstract

Water is one of the most important resources in the world, it is the liquid that gives life to the earth, since the industrial revolution, agricultural processes and population growth, the demand for water has become a critical challenge, therefore, the objective of this project is to evaluate the consumption of the water footprint in rice production in the department of Meta, The water footprint is an indicator of consumption and contamination of fresh water associated to direct and indirect processes, likewise, this is a special temporary indicator, temporary referring to a period of time, the study is carried out in the harvest period B, which includes a start from April or May, spatial associated to the indicators that begin to change or vary according to each geographical area, in this case to the 22 municipalities of the department of Meta. Temperature and precipitation indicators modify the water footprint. The department of Meta is one of the main rice producers in Colombia, therefore, it has been selected as a study area, the analysis was distributed in a period of time between 2019 and 2021, with an analysis in the quantification of blue and green water footprint. It was determined by means of the amounts of water needed for the rice sector in the department of Meta, taking into account the type of soil in each municipality studied, yield, harvested area and rainfall.
