Chapter 9: Analysis of Shrimp Farms’ Use of Land
Ruangrai Tokrisna SELECTED STUDY SITES The development of shrimp farming in Thailand is considered to be the main factor in decreasing mangrove areas along the shoreline in Thailand. In this study the emphasis has been placed on the analysis of shrimp farms’ land use in the selected study sites; a comparison between shrimp farms on the east coast (Gulf of Thailand), in Nakhon Si Thammarat Province, and the west coast (Andaman Sea), in Phang-nga Province. Development on the east coast took place before that on the west coast. Shrimp farms in Nakhon Si Thammarat Province were developed because of the failure of shrimp farms in the eastern region (mainly in Chanthaburi Province). After the disease outbreak and crop failure in the eastern region, shrimp farmers moved down to the south, starting new farms in areas of Songkhla Province and Nakhon Si Thammarat Province along the coastline of the Gulf of Thailand. Shrimp farms along the west coast were established just recently after the failure of the farms on the east coast, probably due to less appropriate topography, land slope and the cost of water intake. In Nakhon Si Thammarat, two areas were selected for the study of shrimp farms’ land use: one in Muang District and another in Pak Panang District. Muang District was an area where shrimp farms were developed first in Nakhon Si Thammarat during the early 1990s. The area was soon overexploited. The over-crowded shrimp farms, beyond the natural carrying capacity, soon led to shrimp disease outbreak...
