Abstract

JIMENEZ-MORENO, María Josefa et al. Analysis of space-time environmental indicators of water, soil and vegetation. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.7, pp.1641-1652.  Epub Dec 04, 2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i7.1806.

Environmental indicators are of the utmost importance because they provide quantitative and qualitative information to assess the use, availability and alteration of natural resources. The objective of this essay was to review from 2006 to 2018 environmental indicators with a spatial and temporal approach, used to assess the environmental condition. Subsequently, the information consulted was classified into three main groups of water, soil and vegetation indicators. After the potentialities of the different methods of environmental indicators were determined, within these relevant findings it was observed that each methodology depends on the quality of the information and the objectives of each study. Among the methodologies analyzed, the most relevant due to the precision of their results, were the indices of vegetation and multicriteria analysis, since it allows to explicitly perceive the parameters of the area that have been modified by human activities. It is concluded that the environmental indicators methodologies depend on the spatio-temporal aspect and the quality of the data, as well as the natural resource to be evaluated.

Keywords : analysis scale; methodologies; multicriteria analysis; natural resources; vegetation index.
