“…Building a regulator at the river mouth about three kilometres from Pak Phanang District is considered to be a means of solving all the problems. This means, it is the important key of the project with the ability to solve the problems ranging from drought, flooding, to intrusion of salty water. It can also provide the people with water supply for consumption and agricultural purposes. If there is no problem concerning land, the regulator can be built fast because the irrigation people already had enough experiences at Bang Nara. In this case, there will be no differences. The construction period is estimated to be three years. Although this one single regulator will not solve all the problems, which requires further construction or extension projects, it however serves as the start of the solutions to all the problems. From this, everything can be done, and separate projects can be established…”The Royal-initiated Pak Phanang River Basin Development Project was launched not only to prevent the intrusion of salty water but also to supply fresh water for the people by functioning as a fresh-water storage reservoir to support agricultural uses and daily consumption as well as to prevent the flooding. Moreover, the Project offers solutions for solving the conflicts between shrimp farmers and rice farmers, and in turn, promotes the harmonious co-existence among the people and nature so as to bring about sustainability.
