  • The Potential of Tourist Attractions: a Case Study of 2 Rural Connecting Districts in the Western Part of Thailand
    The Asian Conference on Sustainability, Energy and the Environment 2013 Official Conference Proceedings Osaka, Japan The Potential of Tourist Attractions: A Case Study of 2 Rural Connecting Districts in the Western Part of Thailand Areerut Patnukao, Sirivilai Teerarojanarat Chulalongkorn University, Thailand 0533 The Asian Conference on Sustainability, Energy & the Environment 2013 Official Conference Proceedings 2013 Abstract The area along the Thai-Burmese border in the western part of Thailand is dominated by mountain ranges lying in a north-south direction. This area is enriched with national parks, wildlife sanctuaries, and diversity of ethnic minority groups. Some of these places are promoted to be tourist attractions. However, sustainable tourism is still in its infancy. The project entitled “Geographical Techniques for the Study of Cultural Diversity and Tourism Development” was launched in 2010. The study area covered the connecting area of two rural districts - Dan Chang district, Suphan Buri province and Ban Rai district, Uthai Thani province. This paper presents the first stage of this project aiming to explore and identify the potential of tourist attractions in the study area. Methodology involved field survey, classification and assessment of potential of tourist attractions, development of GIS tourism databases, and implementation of SWOT analysis. Results showed that tourist attractions are based almost entirely on their cultural and natural heritages. Based on the SWOT analysis, their strengths are in term of the cultural uniqueness and the richness of forestry and wildlife. Their major weaknesses are the incompleteness of physical transportation and facilities and the uncooperative attitudes between the relevant government agencies. The opportunity is that these areas can be promoted to become new tourist attractions at both domestic and international levels.

  • Positional Notation Or Trigonometry [2, 13]
    The Greatest Mathematical Discovery? David H. Bailey∗ Jonathan M. Borweiny April 24, 2011 1 Introduction Question: What mathematical discovery more than 1500 years ago: • Is one of the greatest, if not the greatest, single discovery in the field of mathematics? • Involved three subtle ideas that eluded the greatest minds of antiquity, even geniuses such as Archimedes? • Was fiercely resisted in Europe for hundreds of years after its discovery? • Even today, in historical treatments of mathematics, is often dismissed with scant mention, or else is ascribed to the wrong source? Answer: Our modern system of positional decimal notation with zero, to- gether with the basic arithmetic computational schemes, which were discov- ered in India prior to 500 CE. ∗Bailey: Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA.

Email: [email protected]. 1 2 Why? As the 19th century mathematician Pierre-Simon Laplace explained: It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit. But its very sim- plicity and the great ease which it has lent to all computations put our arithmetic in the first rank of useful inventions; and we shall appre- ciate the grandeur of this achievement the more when we remember that it escaped the genius of Archimedes and Apollonius, two of the greatest men produced by antiquity.

  • • Ceramics from Muang Phan, Chiang Rai Province
    CERAMICS FROM MUANG PHAN, CHIANG RAI PROVINCE by John N. Miksic* The ceramic tradition of northern Thailand bas been a subject of interest to art historians and archeologists, among others, for some time. The development of ceramic technology and products, including high-fired stonewares, is closely linked to the political development of the northern Thai states. The warfare and unstable economic conditions of the late fourteenth and early fifteenth centuries A.D., consequent on • the struggles among several Thai kingdoms, are clearly correlated with the end of ceramic manufacture at the Sawankhalok and Sukbothai kilns. A number of kilns in the provinces of Chiang Mai, Chiang Rai and Lampang seem to have been built at that time, perhaps by potters who were seeking refuge from Ayutthayan invaders (Kraisri 1960: 18)2• Eventually it may be possible to write a comprehensive analysis of the development of Thai ceramics before and after the decline of Sukhothai influence in the late fourteenth ceo tury. It may be assumed that the political events of the time played nearly as important a role in shaping ceramic development as did the hands of the potters themselves.

    Chiang Mai Lampang Lamphun Mae Hong Son Contents Chiang Mai 8 Lampang 26 Lamphun 34 Mae Hong Son 40 View Point in Mae Hong Son Located some 00 km. from Bangkok, Chiang Mai is the principal city of northern Thailand and capital of the province of the same name. Popularly known as “The Rose of the North” and with an en- chanting location on the banks of the Ping River, the city and its surroundings are blessed with stunning natural beauty and a uniquely indigenous cultural identity. Founded in 12 by King Mengrai as the capital of the Lanna Kingdom, Chiang Mai has had a long and mostly independent history, which has to a large extent preserved a most distinctive culture. This is witnessed both in the daily lives of the people, who maintain their own dialect, customs and cuisine, and in a host of ancient temples, fascinating for their northern Thai architectural Styles and rich decorative details. Chiang Mai also continues its renowned tradition as a handicraft centre, producing items in silk, wood, silver, ceramics and more, which make the city the country’s top shopping destination for arts and crafts. Beyond the city, Chiang Mai province spreads over an area of 20,000 sq. km. offering some of the most picturesque scenery in the whole Kingdom. The fertile Ping River Valley, a patchwork of paddy fields, is surrounded by rolling hills and the province as a whole is one of forested mountains (including Thailand’s highest peak, Doi Inthanon), jungles and rivers. Here is the ideal terrain for adventure travel by trekking on elephant back, river rafting or four-wheel drive safaris in a natural wonderland.

  • Smallholders and Forest Landscape Restoration in Upland Northern Thailand
    102 International Forestry Review Vol.19(S4), 2017 Smallholders and forest landscape restoration in upland northern Thailand A. VIRAPONGSEa,b aMiddle Path EcoSolutions, Boulder, CO 80301, USA bThe Ronin Institute, Montclair, NJ 07043, USA Email: [email protected] SUMMARY Forest landscape restoration (FLR) considers forests as integrated social, environmental and economic landscapes, and emphasizes the produc- tion of multiple benefits from forests and participatory engagement of stakeholders in FLR planning and implementation. To help inform application of the FLR approach in upland northern Thailand, this study reviews the political and historical context of forest and land manage- ment, and the role of smallholders in forest landscape management and restoration in upland northern Thailand. Data were collected through a literature review, interviews with 26 key stakeholders, and three case studies. Overall, Thai policies on socioeconomics, forests, land use, and agriculture are designed to minimize smallholders’ impact on natural resources, although more participatory processes for land and forest management (e.g. community forests) have been gaining some traction. To enhance the potential for FLR success, collaboration processes among upland forest stakeholders (government, NGOs, industry, ethnic minority smallholders, lowland smallholders) must be advanced, such as through innovative communication strategies, integration of knowledge systems, and most importantly, by recognizing smallholders as legitimate users of upland forests. Keywords: North Thailand, smallholders, forest management, upland, land use Politique forestière et utilisation de la terre par petits exploitants dans les terres hautes de la Thaïlande du nord A. VIRAPONGSE Cette étude cherche à comprendre le contexte politique de la gestion forestière dans les terres hautes de la Thaïlande du nord, et l’expérience qu’ont les petits exploitants de ces politiques.

  • Geographical Information System Based Model of Land Suitability for Good Yield of Rice in Prachuap Khiri Khan Province, Thailand
    Sci., Tech. and Dev., 31 (1): 1-9, 2012 GEOGRAPHICAL INFORMATION SYSTEM BASED MODEL OF LAND SUITABILITY FOR GOOD YIELD OF RICE IN PRACHUAP KHIRI KHAN PROVINCE, THAILAND WALAYAT HUSSAIN*1, OSAMA SOHAIB1, AFTAB AHMED2 AND MUHAMMAD QASIM KHAN2 1Department of Computer Science, Balochistan University of I.T, Engineering and Management Science, Quetta, Pakistan. 2Faculty of Information and Communication Technology, Balochistan University of I.T, Engineering and Management Science, Quetta, Pakistan. Abstract Correct assessment of land is a major issue in agricultural sector to use possible capability of any land, to raise cultivation and production of rice. Geographical Information System (GIS) provides broad techniques for suitable land classifications. This study is GIS based on land suitability analysis for rice farming in Prachuap Khiri Khan Province, Thailand, where the main livelihood of people is rice farming. This analysis was conducted considering the relationship of rice production with various data layers of elevation, slope, soil pH, rainfall, fertilizer use and land use. ArcView GIS 3.2 software is used to consider each layer according to related data. To weigh every coefficient, ranking techniques are used. It was based on determining correlation of rice production and these variables. This analysis showed a positive correlation with these variables in varying degrees depending on the magnitude and quality of these factors. By combining both data layers of GIS and weighted linear combination, various suitable lands have been developed for cultivation of rice. Integrated suitable assessment map and current land were compared to find suitable land in Prachuap Khiri Khan Province of Thailand. As a result of this comparison, we get a land which is suitable for optimum utilization for rice production in Prachuap Khiri Khan Province.
