Abstract
El objetivo de este trabajo es el desarrollo, con la participacion de los grupos de un colectivo. Esta experienca se apoya en una investigacion llevada a cabo con agricultores y responsables profesionales (Proyecto Aquae (4) en la cuenca hidrografica para evaluar el consumo de agua, las perdidas de nitratos de la zona, y de 2) simular escenarios para analizer posiblres mejoras en la gestion. Se han probado dos tipos de escenarios con el objectivo de ajustar el uso del agua a los columenes disponibles y de disminuir las perdidas de nitratos: en primer lugar una optimizacion del riego y de la fertilizacion, y despues una gestion de las rotaciones a escala de zona (cinco zones en las que se ha dividido la cuenca hidrografica), asi como a escala de la cuenca. El modelo permite evaluar, para distintos escenarios de gestion, el coste que supone para los productores agricolas el respecto de las normas establecidas sobre uso aqua y fertilizacion en funcion de la variabilidad climatica interanual...The aim of this study is to develop simplified tools and methods in collaboration with the participation of local stakeholders for facilitating collective decision-making. The project is based on a series of experiments carried out with farmers, environmental officers and researchers (Aquae proyect) on the Aveyron-Lere catchment area. Within this framework: 1) a model of the catchment was constructed in order to examine water consumption and nitrate losses in the area, and 2) scenarios were simulated so as to assess possible management improvement. Two types of scenarios were tested with the objective of limiting water use to available volumes and reducing nitrate losses: first, irrigation and fertilization optimization; after that crop rotation management at local scale (in the five zones defined in the catchment), as well as the scale of the whole basin. The model allows the evaluation, for the different management scenarios, the cost for the farmers of respecting current water and fertilization regulations, as a function of the inter-annual climatic variability.
