Songkhla Lake Basin has a long history of at least 6,000 years and has a wide variety of tourism resources including nature, history, beliefs, culture and various traditions of the local people. It covers 3 provinces, the whole area of Phatthalung, 12 districts of Songkhla and 2 districts of Nakhon Si Thammarat Province. It has an area of approximately 8,727 square kilometers. There are many tourist attractions because the basin has a long history through different eras, natural, historic, ancient sites, and the culture of the local people. In 2018, both Thai and foreign tourists visited Songkhla and Phatthalung, which is the main area of Songkhla Lake Basin. The total number of tourists that came was 7,628,813 and 1,641,841 and an income of 68,252.64 and 3,470.96 million baht was generated from each province, respectively (Ministry of Tourism and Sports, 2020). Although Songkhla Lake Basin has various tourist attractions, the promotion of tourism with the involvement of government agencies in the past mainly focused on promoting tourism along with the tourist attractions rather than encouraging tourists to experience and learn the culture of the people living in the area; the culture that reflects the uniqueness of the people in the south. This study, therefore, aims to find creative tourism activities in SLB in order to increase the value of tourism resources, create tourism activities that are aligned with the resources available in the community and increase the number of tourists in the area. Data for this study were collected using a secondary source of data collection method. It was done through a literature review of related documents, texts, magazines, and research which focus on Songkhla Lake Basin as a guideline for designing tourism activities. The field survey was done through twelve community-based tourism sites in SLB to find creative tourism activities. Data on each activity were collected in detail by interviewing the tourism community leaders and the local people. Content analysis was used to describe the individual open-ended questions by focusing on the important issues and the information obtained was presented as a narrative. Keywords: Songkhla Lake Basin, Creative Tourism, Local Wisdom

The Songkhla Lake Basin (SLB) located in Southern Thailand, has been increasingly polluted by urban and industrial wastewater, while the lake water has been intensively used. Here, we aimed to investigate cyanobacteria and cyanotoxins in the SLB. Ten cyanobacteria isolates were identified as Microcystis genus based on16S rDNA analysis. All isolates harbored microcystin genes, while five of them carried saxitoxin genes. On day 15 of culturing, the specific growth rate and Chl-a content were 0.2–0.3 per day and 4 µg/mL. The total extracellular polymeric substances (EPS) content was 0.37–0.49 µg/mL. The concentration of soluble EPS (sEPS) was 2 times higher than that of bound EPS (bEPS). The protein proportion in both sEPS and bEPS was higher than the carbohydrate proportion. The average of intracellular microcystins (IMCs) was 0.47 pg/cell on day 15 of culturing, while extracellular microcystins (EMCs) were undetectable. The IMCs were dramatically produced at the exponential phase, followed by EMCs release at the late exponential phase. On day 30, the total microcystins (MCs) production reached 2.67 pg/cell. Based on liquid chromatograph-quadrupole time-of-flight mass spectrometry, three new MCs variants were proposed. This study is the first report of both decarbamoylsaxitoxin (dcSTX) and new MCs congeners synthesized by Microcystis.

This article aims to determine a pattern of rural tourism that harmonizes with the Songkhla Lake Basin (SLB) resources in southern Thailand. Data were collected through a field survey, focus group discussions involving tourism stakeholders, a snowball sampling technique with SLB experts, and questionnaires with 400 tourists. The study found that the SLB tourism resources are located in a mountain range, in the foothills, in the lowlands, on the coast, and on a lake. The tourism field consists of a natural way of life; belief in Buddhist doctrines and the presence of monks, natural beauty, and sacred objects; folklore plays; local traditional events; and archaeological and historical sites. Ecotourism, cultural tourism, archaeological tourism and historical tourism are the aspects of rural tourism that harmonize with components of the SLB resources.

The objectives of this study were to explore the impacts of Thailands eleven National Economic and Social Development Plans (NESDP or NP) on the development, natural resources, and environment of the Songkhla Lake Basin (SLB), Thailand, and to propose policy recommendations for this development. Data on development in the SLB were collected through literature reviews and through four focus group discussions for related stakeholders in the four sub-basins. Our results showed that the focus of development changed from economic development in NP1 through NP7 to a new model of holistic people-centered development with an emphasis on sustainability in NP8 through NP11. During this time (1961-2013), economic development has progressed in the SLB. For instance, 443 irrigation projects were developed to support expanded rice paddy fields, the area of shrimp farms increased to a current total of 60,174 rais, rubber plantations encroached into 30% of the total watershed area, and the number of factories increased to 2,748. This increased development has led to water pollution, sedimentation in Songkhla Lake, degradation of the watershed, and the depletion of fishery resources, requiring urgent remedial action. We recommend that mechanisms are provided for the public to fully participate in formulating basin development plans by, for example, establishing a Songkhla Lake Basin Development Institute and conducting a basin-level strategic environmental assessment.
