Book excerpt: Inhaltsangabe:Abstract: Tropical land use changes, predominantly the clearing of tropical rain and monsoon forests, have long been recognized as a trend with dramatic consequences. FAO estimated the global loss of rain forest area at 0.6 to 0.9 % per annum in 1993. Most of it can be attributed to the conversion of forest lands to agricultural areas. In Southeast Asia, two countries have suffered from this phenomenon more than any other nations: the Philippines and Thailand. Between 1961 and 1975, the forest reserves of Thailand have been reduced from 57 % to 37 % of the total area, while at the same time the area put to agricultural use has almost doubled. Only a small part of that process was due to organized resettlement programmes; to an overwhelming extent the deforestation has been performed 'illegally' by spontaneous activities of the rural population. The share of forests further declined to 28.9 % in 1998, at a current rate of -0.7 % per year, meaning that Thailand's forest cover has roughly halved since 1960. The author of this thesis stayed as a visiting researcher at the Asian Institute of Technology (AIT), immediately north of Bangkok, for 6 months from November 2000 until April 2001. The AIT is a small international university for graduate studies with students and teachers from more than 40 countries. The core institution for this scientific cooperation was the Asian Center for Research on Remote Sensing (ACRoRS) of the AIT's School of Advanced Technologies (SAT). Field work in Northeast Thailand was carried out in two legs in February and April 2001. As an underlying principle of this study, it was attempted to incorporate problems from the realms of social as well as physical geography, i.e. to maintain a balance between questions of applied geography (regional studies) and remote sensing. This also means that no special focus was put on advanced RS methodology such as the development of new image processing techniques; the study is rather based on a somewhat holistic approach, joining aspects from many different fields of science as diverse as geology, geomorphology, climatology, agriculture and agricultural economics, sociology, ethnology, politics, and spatial planning. Accordingly, the basic objectives were: - to give a geographical description/characterization of the Northeastern Region of Thailand in terms of its physical properties as well as its social and economical peculiarities. - to try a quantification of forest [...]

Download or read book Using Remote Sensing and GIS Techniques to Assess Land Use land Cover Changes in the Nan Watershed Thailand written by Chamaporn Paiboonvorachat and published by . This book was released on 2008 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, Landsat 5 TM images obtained in 1995, 2000, and 2005 were used to categorize land use and land cover (LULC) and assess LULC changes and dynamics in the Nan watershed, Thailand using hybrid classification and post-classification change detection methods, respectively. Aerial photographs, digital LULC maps, and topographic maps were utilized to assess classification accuracy. Classified images together with ancillary data using Multi-Criteria Geographic Information System (GIS) Modeling were used to identify potential risk areas of soil erosion. The overall classification accuracy derived from the stratified random sampling pattern was 80.9% for 1995, 77.4% for 2000, and 86.0% for 2005. The results are satisfactory for LULC classification. Uncertainty of classification was mainly observed in green vegetation cover categories, which are forests, agricultural lands, and natural plants in wetlands. The study period revealed a significant increase in paddy fields and croplands at the expense of closed canopy forests. Paddy fields and croplands increased by 2.56% and 3.37%, respectively. Closed canopy forests, on the other hand, decreased by 3.64%. This change was caused by an increase in population within the watershed during the study period. Closed canopy forest, open canopy forest, and cropland categories were major drivers of LULCC in the Nan watershed. In 2010, the probability of change from forests to paddy fields and croplands are approximately 0.13 and 0.16, respectively. Expansions of high risk areas of erosion in northwestern and southeastern regions of the watershed in the two later years related to an increase of agricultural lands. Deforestation and environmental degradation in the Nan watershed are mainly influenced by population growth and increase demand for land uses to support human activities.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landsat 7 Enhanced Thematic Mapper (ETM), Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images obtained in 1991, 2005 and 2014 with maps, and field survey data were used to classify land use and land cover (LULC) changes over 23 years and predict soil erosion risk locations in the Khlong Kui watershed (73,700 ha), Prachuap Khiri Khan province, Thailand. Classified images together with soil features, slope and rainfall data were used to identify potential risk areas of soil erosion. Based on field check data, the overall classification accuracy was accessed from random samples that resulted as 80% for 1991, 83% for 2005 and 86% for 2014. The study discovered that rice field and rangeland increased by 1.12 and 2.81%, respectively, deciduous forest, and on the other hand, it decreased by 8.28%. GIS analysis identified the potential risk areas of soil erosion as 46,431 ha (0.63%) at very high risk.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: This dissertation investigates the relationships between road network development and land cover in Lop Buri Province Thailand between 1989-2006. The dissertation is divided into three major chapters (2-4), each of which is a stand-alone journal paper. Chapter 2 examines the relationship between distance to roads and land-cover trajectories. First land-cover classes were determined; then the distance from roads was mapped against the land-cover. The results show that most of land-cover change occurs within 6 km of roads, whether existing or newly built. Chapter 3 examines other drivers of land-cover change by using logistic regression analysis. The focus was on two major particular trajectories: changes to upland crops and loss of forest. The results showed the most influenced for these two types of land-cover trajectories are slopes, distance to forest edge, and distance to towns. Lastly, in Chapter 4, network analyst was use in determining how connectivity can relate to land cover and land-cover change. Fifty-six intensive study areas (ISAs) were selected in this analysis. Then I compared the differences between each type of land cover in the areas that have gone through road network development and the areas that have not gone through road network development. The results revealed that areas that have road network development have significant changes in the amount of forests, upland crops, and plantation landscape. This dissertation concludes that roads are the main contributor of land-cover change in Lop Buri province. Thus, human activities of road building can drive the environmental changes of land-cover change. This study has enhanced the knowledge of human-environmental interaction and transportation geography through incorporating an array of theories, methods, and tools such as GIS, remote sensing, and spatial statistics.
Download or read book The Geology of Thailand written by Michael Frederick Ridd and published by Geological Society of London. This book was released on 2011 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first volume in the English language to cover the entire range of the geology of Thailand since the joint Thai-US account by Brown et al. exactly 60 years ago. Over this period there has been a phenomenal growth in interest in this core area of SE Asia. This has been led by geologists in Thailand, but with important and highly significant input from geologists based elsewhere in Asia and in Europe, Australasia and North America. Some of that research was prompted by commercial considerations, since Thailand has important energy and mineral resources, while other research has sought to understand better the stratigraphic and structural history, including the plate-tectonic story which Thailand's rocks reveal. This new volume seeks to bring together all of this knowledge into a single accessible book; it is the work of an international team drawn from Thailand, Japan, Australia, USA, Canada, Germany and the UK.

Available in PDF, EPUB and Kindle. Book excerpt: This book about the Mekong Delta presents a unique collection of state-of-the-art contributions by international experts from different scientific disciplines about the characteristics and pressing water-related challenges of the Mekong Delta in Vietnam. The Mekong Delta belongs to one of the areas, which are to expect the largest challenges concerning environmental change and climate change induced sea level rise . The Delta acts as the “rice bowl” of Southeast Asia and is home to over 17 Million people, who need to cope with ecologic as well as socio-economic changes linked to the rapid economic development of the country. Annual floods, severe droughts, salt water intrusion, degrading water quality, tropical cyclones, hydrologic changes due to hydropower projects in the upstream of the Mekong, coastal erosion, and the loss of biodiversity are some of the problems in the region. Heterogeneous resource management responsibilities, and the fact that the Mekong – and thus also the Delta – is influenced by six countries aggravate the situation. Integrated water resources management and fostered cooperation and information exchange are pressing needs for the sustainable development of the Delta.
