| The management of river ecosystems is a major issue which is subject to controversy due to the large number of factors, environmental and human, involved in its development. Stakeholders¿ participation is a fundamental aspect for modeling effective management. The application of Fuzzy Cognitive Maps (FCM) for developing a fluvial management model is presented in this research work. Based on the knowledge of seven experts in fluvial ecology a cognitive map about Esla river basin in Spain was developed. This map was composed of of 13 variables with 114 connections reflecting a causal relationship network. The most central variable in the collective map was Cross barriers, dams and weirs. The main objective is to develop a methodology based on FCM as useful tool for decision making in river management, taking account the expert knowledge. We determined the steady state conditions of our system based on the centrality of each variable to generate a model of the behavior of Esla river basin. Using our FCM expert model we perform a number of simulations from different possible scenarios: reducing the number of cross barriers, increasing natural flow regime, improvement of riparian vegetation and bank conditions and finally a scenario without impact management. As a result, the expected responses of river concepts were obtained according to the feature and intensity of planned scenarios. Thus, FCM methodology enabled us not only to understand the perception of current fluvial ecosystems but also to generate realistic management scenarios based on knowledge of experts in this field. | |
