Here we value only water and we do not take in account cost. In addition, water value is limited to Use and non use value (no option value) Not sure we add the Human impact bubble, the one with coping strategies.
Not sure about “grazing land” and “spawning ground”, probably more for Ecosystem value We do not here use “Option values” I add values assessed to other aquatic resources in Cambodia and Lao because I think it is really important and they are often not valued
