Integration of MultiCriteria Decision Analysis in GIS to develop land suitability for agriculture: Application to durum wheat cultivation in the region of Mleta in Algeria

摘要: Due to constant decrease in farmlands, it is important identify the best lands useful for sustainable agriculture (productive and profitable that protects environment socially equitable). This requirement has resulted development of land suitability maps by combining several factors various natures differing importance. The integration MultiCriteria Decision Analysis approaches (MCDA) a Geographical Information System (GIS) provides powerful spatial decision support system which offers opportunity efficiently produce these maps. Indeed, GIS tool analyzing data establishing process support. Because their aggregation functions, MCDA methods can facilitate making situations where solutions are available, criteria have be taken into account decision-makers conflict (Dias et al., 2002). parameters classification used this work inspired from FAO (Food Agriculture Organization) approach dedicated agriculture. A been developed map It incorporates multicriteria analysis method ELECTRE Tri (ELimitation Et Choix Traduisant la REalite) (ArcGIS) within program package environment. tested on area Mleta Algeria. durum wheat produced. Through obtained results, appears method, integrated ArcGIS 9.2 ESRI, better suited problem time saving during was considerable. coherence confirms effectiveness.
