Soil salinization in irrigated areas is a soil degradation process that affects both crop productivity and environment. It is predicted that climate change could affect the precipitation pattern and/or increase the average temperature at the Mediterranean region. This new scenario can be simulated with the SALTIRSOIL model to know the effect of climate change in soil salinization. This model was fully integrated within a Geographical Information System (GIS) framework to extend its applicability to the whole irrigation area of Segura and Vinalopo lowland (Spain). Three scenarios were simulated to evaluate the climate change effect in soil salinity: i) non-climate change ii) with climate change iii) same conditions as scenario ii but with an increase of 20% in irrigation rates. A total increase of 28% in soil salinity was simulated when comparing the current climatic conditions with the climate change scenario. An increase of 50 hm3 of irrigation water could practically offset the effect of climate change in soil salinity.
