A WMO - World Meteorogical Organization publica o Relatório provisório State of the Global Climate 2020, dando conta do contínuo aumento das concentrações dos principais gases com efeito de estufa, CO2, CH4, e N2O, da subida do nível do mar, do aumento temperatura média global em 2020, e de muitos outros fenómenos climáticos extremamente preocupantes.

A UNAC - União da Floresta Mediterrânica publicou o "Catálogo de Projetos RIAAC–AGRI", resultante de um levantamento exaustivo da informação científica existente no âmbito da RIAAC-AGRI - Rede de impacto e adaptação às alterações climáticas nos setores agrícola, agroalimentar e florestal, que tem o objetivo de transferir boas práticas e novos conhecimentos para qualificar as empresas e a intervenção dos agentes de desenvolvimento rural no que respeita à adaptação às alterações climáticas.

The impacts of climate and associated socio-economic changes on water availability, including supply and demand, quality, and storage volume, were evaluated for the Vale do Gaio reservoir in southern Portugal, located in a dry Mediterranean climate and already under drought stress.

The SWAT model was applied with 6 scenarios for 2071–2100, involving two storylines (A1B and B1) with individual changes in climate (−9% rainfall, increasing in winter by+28 to +30%), socio-economic conditions (an increase in irrigation demand by 11%, and a replacement of cereals and pastures by sunflower), and a combination of both. Most future scenarios resulted in lower water availability, due to lower supply (−19 to −27%) combined with higher irrigation demand (+3 to +21%).

This resulted in more years with limited irrigation supplies (presently: 28%; scenarios: 37 to 43%), although limitations were mitigated by lower losses to excess discharge. Land-use changes also decreased quality by increasing P concentrations (+29 to +93%). Impacts were more severe in scenario A1B than in B1, and in combined changes than in climate or socio-economic changes only.

Water availability was resilient to climate change, as impacts led only to a moderate aggravation of present-day conditions. Lower future water availability could be addressed by supply and demand management strategies and, in the most extreme scenario, by water transfers fromregionalwater reserves;water quality issues could be addressed through land-use policies. Results also highlighted the importance of taking the characteristics of water supply systems into account when designing
adaptation measures for future changes.
