Determination of Empirical Environmental Indices for the Location of Cemeteries—An Innovative Proposal for Worldwide Use

Abstract

Cemeteries are a source of environmental contamination, as they hold hundreds of human corpses in different stages of decomposition. Therefore, the current research developed a new tool, which is easily applied, to determine the potential environmental contamination generated by current cemeteries within their ecosystems. The linear equations developed, with a number of variables between 10 and 3, allow for obtaining empirical indices to evaluate the suitability of a site, regardless of the geographical area in which it is located, through a variety of sources. In order to obtain the equations and, therefore, the indices, a hierarchy was performed using the Saaty matrix. With such a matrix, different ranges of affectation were established for each variable and relative values were assigned that cover all probabilities quantitatively, from the least probable to the most likely. With the linear equations, three verification runs were conducted, obtaining satisfactory results compared with the location map of cemeteries obtained in previous studies. These equations will constitute a tool of fundamental use for local governments, which will allow for the evaluation of existing cemeteries and use of the methodology described in preliminary analysis, to save resources and have a starting point for an efficient land use plan.
