Assessing the Long-Term Impact of Traditional Agriculture and the Mid-Term Impact of Intensification in Face of Local Climatic Changes

In the Mediterranean basin, edaphic salinization, sodification and alkalinization related to anthropic pressures climatic changes may hinder ecosystem sustainability. It is pertinent study mid long-term variability of these soil characteristics in face off macro agricultural system use (i.e., irrigation or rain-fed). Four irrigated soils from Caia Irrigation Perimeter (Portugal), Fluvisols, Luvisols, Calcisols Cambisols were analysed mid-term, 2002 2012, for its available Ca2+, Mg2+, K+ Na+ content. Overall, significantly increased during period this by 25%, 8% 7%, respectively. Soil organic matter (SOM) pH area already assessed previous studies with overall SOM remaining constant (p ≥ 0.05) increasing < 0.01) 5%. We provide predictive maps CROSS & HotSpot evolution map 2012. Rain-fed long-term, 1965 their SOM, non-acid cations (Ca2+, Na+) While exchangeable Mg2+ 23%, 8%, 60%, 21% 193%, respectively, decreased 50%. These results be local climate as, according Thornthwaite classification, it went sub-humid great water excess (C1B2s2b4) normal 1951/1980 moderate (C1B2sb4) 1981/2010 semi-arid little none (DB2db4) 1991/2020. The areas region are slowly departing sustainable goals conservation better management practices, that address registered area, could adopted.
