In Honduras, 137 of the 298 municipalities are considered vulnerable to drought under the National Action Plan to Combat Desertification and Drought (PANLCD), which is the technical and strategic instrument developed in 2005. Rainwater harvesting, also known as "water harvesting", may be one of the solutions to meet the challenge posed by the low availability of liquid in various regions of the country. In this research, two models were compared and combined to select the optimal sites for the establishment of water harvests in the municipalities of Caridad, Aramecina, Goascorán, Langue and Alianza. The method of Weighted Linear Combination (WLC) and Binary Method were applied on six spatial criteria, and a model was subsequently constructed combining both results, obtaining 3% of the total area of study (3,529.28 Ha) with a high potential for construction of water crops.
