Abstract
This research paper presents a methodology for the analysis of vulnerabiÂlity of water supply sources with regional results (Popayan and Cajibío), considering the following points: 1) incorporation of relevant indicators of municipal water supply sources, 2) Local knowledge on perception, and identification of climate related problems, 3) mathematical procedures and adjust the algorithm for calculating the vulnerability and 4) coordination with territorial planning instruments. As a result, the vulnerability in the current scenario of the Rio Las Piedras subbasin (Popayán) is medium low (0.42) product generated by adaptive capacity developed synergistic processes between local actors; in contrast, the basin of the river Michicao (Cajibio) has a high average vulnerability (0.54) due to social dislocation, low institutional presence and zero environmental investment.
