Available in PDF, EPUB and Kindle. Book excerpt: LA MISE EN PLACE DE PROGRAMMES DE REDUCTION DE LA POLLUTION DIFFUSE D'ORIGINE AGRICOLE NECESSITE DES MOYENS DE SUIVI ET D'APPRECIATION DES ACTIONS ENTREPRISES. DANS LE CADRE DU CONTRAT DE BAIE "RADE DE BREST", UNE METHODE DE DIAGNOSTIC DE RISQUE DE POLLUTION DIFFUSE AZOTEE EST MISE EN PLACE SUR LE BASSIN VERSANT DE L'ELORN, CARACTERISE PAR UN ELEVAGE INTENSIF. LA COMBINAISON D'UN INDICE DE PRESSION DE POLLUTION AVEC UN INDICE DE SENSIBILITE DU MILIEU DANS UN INDICE DE RISQUE PERMET DE TENIR COMPTE DES DEUX ASPECTS DU PHENOMENE DE POLLUTION DIFFUSE : LA PRODUCTION ET LE TRANSFERT. L'INDICE EST CONSTRUIT PAR L'INTEGRATION ET LE CROISEMENT DE DONNEES RELATIVES AU MILIEU ET AUX PRATIQUES AGRICOLES DANS UN SIG. CES DONNEES SONT ISSUES DE L'ETUDE DETAILLEE D'UN BASSIN VERSANT EXPERIMENTAL, LE KEROUALLON, SITUE SUR UN AFFLUENT DE L'ELORN. L'INDICE DE RISQUE EST VALIDE A L'AIDE D'UN MODELE DE LESSIVAGE DE NITRATES (BURNS) QUI PERMET DE RETROUVER LE FLUX DE NITRATES A L'EXUTOIRE. L'INDICE DE RISQUE PERMET DONC DE FAIRE UN DIAGNOSTIC DE POLLUTION AZOTEE SUR LE BASSIN VERSANT EXPERIMENTAL. SON DOMAINE D'APPLICATION EST CEPENDANT LIMITE AUX REGIONS D'ELEVAGE INTENSIF, CARACTERISEES PAR UN CLIMAT OCEANIQUE. L'EXTRAPOLATION DE L'INDICE DE RISQUE SUR LE BASSIN VERSANT DE L'ELORN REPOSE SUR UNE AGREGATION ET UNE SIMPLICATION DE L'INFORMATION EN FONCTION DES DONNEES DISPONIBLES A L'ECHELLE DE L'ELORN. LA TELEDETECTION EST UTILISEE POUR RECUEILLIR L'UTILISATION DU SOL QUI EST INTEGREE DANS L'INDICE DE RISQUE. LE SIG PERMET DE VERIFIER LA PRECISION DES DONNEES UTILISEES. L'INDICE DE RISQUE EST CALCULE SUR DES SOUS BASSINS VERSANTS DE L'ELORN ET VALIDE PAR UNE COMPARAISON AUX CONCENTRATIONS EN NITRATES DE CHAQUE SOUS BASSIN VERSANT. L'INDICE DE RISQUE SIMPLIFIE PERMET DE CLASSER LES SOUS BASSINS VERSANTS DANS UN ORDRE DE PRIORITE DANS LE CADRE DE LA MISE EN PLACE D'ACTIONS DE REDUCTION DE LA POLLUTION DIFFUSE.
