Water management decisions not only implicate technological, scientific, administrative, economic, and political
aspects, but also implicate social aspects (i.e. human attitude towards water use). Because water is our most
important natural resource, every person has the right of access to water. For instance, usually water is accessible
and fees are not expensive. However, since people have the right of access to water, human attitude towards water
use is associated with a short-term value [10]. Therefore, water wastageis common, such as citizens who waste tap
water, farmers who over-watercrops, and other people who pollute water without any penalty (i.e., pollution from
up-stream to down-stream by mines and factories sewages). Even though problems caused by mining or agriculture
run-off can originate far away from the coast, the pollution also affects the ocean. The natural environment of sea
species has been changed and people have to stop fishing and doing recreational activities. As a result of many
actions combined, eutrophication emerges, especially close to the estuaries. Therefore, a holistic and shared attitude
of importance towards the use of water is needed. People need to understand that their actions have a large impact
on water resources and an irresponsible use of water can have terrible consequences, such as health problems and
affecting natural habitats, because ofa change in the hydrological balance.
