The efficient management of conflicts between uses and activities in the marine-coastal environment is fundamental for the success of Marine Spatial Planning (MSP). Our aim was to conduct a geo-analysis of uses and activities present in the jurisdiction of the harbor master of Tumaco and Guapi in Colombia to identify potential conflicts. We used geographic information on uses and activities of the marine-coastal environment available in national geo-portals, 23 interinstitutional experts were consulted to carry out the weighting of the conflict matrices, an analysis of the interactions between the uses and activities supported by spatial analysis was carried out, the main conflicts were identified according to specific criteria and the cartography for the location of the conflicts was carried out. A database with 39 geographic layers was generated, the highest density of uses and activities was found in inland waters, marine fauna obtained 11.81 % of the total interactions, 73 potential conflicts were identified, where 23.29 % corresponded to a high Conflict Index and 57.53 % of the conflicts occurred between user-environment. With these results, we contribute to the management of Colombian marine-coastal within the context of the MSP.
