The best policy position on ICM, is the one that follow the concept of "given water a space". That is reduce/prevent development that tend to squeeze on catchment areas. In addition, it is important to accept the connect between river catchment and the coast of the lake they emptied to. Thus the ICM and integrated coastal/lake management should have a linkage, because some development eg. dam construction on a river could have a significant impact on the coast. Particularly the morphdynamic of the estuary  and the coastline downdrift.
