Abstract

Problems of watersheds especially, water quantity-related problems are the lack of water in dry season, flood in wet season, low water quality standard and inconsistent stream-flow throughout the year.


Land use in Petchaburi watershed which does not comply with the cabinet resolution on watershed classifications in the West, the Central region and Pasak watershed in 1995 (B.E. 2538) resulted in changes of the use of land during the past 20 years (1987 – 2017 (B.E. 2530-2560). It was found that 9 percent of the forest land in Petchaburi watershed has been decreased while 2 percent of agricultural land, urban and built-up land, water body and other use of land and 3 percent of miscellaneous land have been increased. In order to discover causes of changes in land use, this study has been conducted. The results of the study show that government projects which do not comply with the cabinet resolutions are one of the causes triggering the change of land use in that area. Basically, government projects have to be approved by the cabinet resolution. However, 7 out of 20 projects do not comply with land use measures according to the cabinet resolution on watershed classification namely, reservoir construction projects, the project to use land outside reserved forest as agricultural land, highway construction project, land transfer to temple and mining project. Such projects trigger change of land use in the surrounding areas and affects watershed functions.
