The outcomes of this deliverable serve as a foundation for the various tasks in other WPs of OPERANDUM. For instance, the evidence summarised from Section 3 to Section 7, feeds into WP2 to WP7 for design/co-design and implementation of NBS for flooding, droughts, salt intrusion, landslides, coastal erosion and storm surge, nutrients and sediment loading across OPERANDUM OALs. Overall, the reviewed documents showed that hydro- meteorological risks occur more regularly with a strong increase in intensity to cause significant loss of life and economic damage in OPERANDUM OAL countries and these hazards are projected to increase in severity and duration under future climate change scenarios. In response to this, in OPERANDUM OALs, different types of NBS such as green, blue and hybrid approaches were used and are under implementation. This deliverable is divided into 8Sections. This report contains 123 pages, 42 figures and 20 tables.
