Introduction 1. The Fourth Greater Mekong Subregion Corridor Towns Development Project (GMS- CTDP-4 or Project) will support the Governments of Cambodia and the Lao People’s Democratic Republic (PDR) in enhancing the competitiveness of selected towns located along the Central Mekong Economic Corridor in the Greater Mekong Subregion (GMS). It is aligned with the Government of Cambodia’s Rectangular Strategy for national development. The third phase (RS- III 2013–2018) identifies integrated urban development as a priority and recognizes the need to manage environment and climate change to ensure the sustainability of Cambodia's economic growth and social development. The Project is also underpinned by Cambodia’s National Green Growth Road Map (2010) which promotes access to clean water and sanitation. In Cambodia, the Project will improve urban services and enhance regional economic connectivity in the participating towns of Kampong Cham, Kratie, and Stung Treng. 2. The project environment classification is confirmed as Category B. This report constitutes the initial environmental examination (IEE) and environmental management plan (EMP) for the proposed subprojects in Cambodia.1 The IEE was carried out in accordance with the Safeguard Policy Statement (2009) of the Asian Development Bank (ADB), and Cambodia’s Law on Environmental Protection and Natural Resource Management (Preah Reach Kram/NS-PKM- 1296/36) 1996, and its sub-decrees and implementing guidelines. B. Project Scope 3. The Project outputs include: (i) centralized wastewater and stormwater drainage facilities to improve sanitation and control flood risks, (ii) controlled landfills for improved municipal waste disposal, solid waste collection vehicles to enhance collection activities, and the closure of existing dumpsites (Stung Treng and Kratie), (iii) town center landscaping and rehabilitation to create livable public spaces that foster tourism benefits, (iv) information and communication technology (ICT) based government systems to optimize operational transparency and resource efficiency in managing the new infrastructures, and (v) provincial five-year socioeconomic development plans to promote regional economic connectivity and coordinate their strategies (Table 1).

The Project is expected to improve the urban environment in the three towns, reduce their vulnerability to environmental and climate risks, and improve their climate resilience level and 1 The IEE and EMP (i) identify and assess potential impacts and risks from subproject implementation on the physical, biological, physical-cultural and socioeconomic environments, and (ii) recommend measures to avoid, mitigate and compensate adverse impacts, while enhancing positive impacts. ii quality of life. It will provide them with improved stormwater, wastewater and solid waste management services, and in all three, formulate a provincial development strategy and strengthen institutional capacities in resilience town planning. The Project also includes town center enhancements in Kratie and Stung Treng. The anticipated positive impacts and environmental benefits are presented in Table 5.1 of the IEE. 5. Kampong Cham Subproject. The proposed combined sewer system in Kampong Cham will be built in the main urban area to serve four communes, namely, (i) Krong Kampong Cham (100%), (ii) Veal Vong (100%), (iii) Sambor Meas (50%), and (iv) Boeng Kok (10%). The sewer lines will be laid along roads in the main urban area and will affect at least eleven schools, businesses, one hospital, an orphanage, two temples, two mosques, and one church along the roads in Boeng Snay and Boeng Bassac. The impacts of the combined sewer will primarily occur during the construction phase. The impacts will be temporary but will potentially affect community health

ARMSTRONG Research School of Earth Sciences, The Australian National University, Canberra, ACT, Australia D. O’REILLY School of Archaeology and Anthropology, The Australian National University, Canberra, ACT, Australia Strontium (Sr) isotope ratios (87Sr/86Sr) measured in human skeletal material can increase one’s understanding of the residential behaviour and resource-acquisition strategies of past populations. The paper maps bioavailable 87Sr/86Sr variation in 183 plant and soil samples across Cambodia. Bioavailable 87Sr/86Sr, as measured in plants, differs significantly between four major geological units. The data set will support future investigations of skeletal material from Cambodian archaeological sites. Baseline 87Sr/86Sr data should be applied judiciously to skeletal populations, and in concert with other lines of evidence, to identify potential geo- graphical outliers rather than to ascribe specific locations from which individuals may have moved. KEYWORDS: CAMBODIA, STRONTIUM ISOTOPES, BASELINE MAP, PALEOMOBILITY INTRODUCTION Cambodia has long held archaeological interest (Corre 1879; Mansuy 1902; Mourer 1994), where the primary focus has been on the rise and fall of the Khmer Empire centred on Angkor (Fletcher et al. 2006). Much of what is known about the Angkorian civilization is derived from the magnificent religious monuments, artworks and inscriptions, and, in recent years, from the exquisitely detailed record of landscape modification obtained from high-resolution airborne la- ser scanning technology (Evans and Fletcher 2015; Evans 2016; O’Reilly et al.

    Translating 2D Seismic to New Oil and Gas Resources Kathleen Dorey Petrel Robertson Consulting Ltd. Summary Considering the challenging times in the Canadian Oil and Gas industry for the geophysical profession, this talk will highlight the successful and value added application of geophysical processing and interpretation on behalf of a Canadian oil and gas company in Southeast Asia. The work processes will be outlined and the economic value they add will be highlighted throughout the presentation. In addition, the newly identified oil and gas resources will be quantified which, in the future, may trigger the beginning of hydrocarbon independence for that country. Introduction The relevant geology, stratigraphy and structural regimes will be presented as a backdrop to the geophysical reprocessing, mapping and analysis of recently generated prospects over a Laos oil and gas concession. The closest production is from the SinPhaHorn gas field to the west on the Thailand side of the basin. The field was discovered in 1983 and currently produces 90 Mmcf/day. A total of 2600 km of 2D legacy seismic lines have been acquired over the concession area covering 2.9 million acres and have been integrated into the interpretation and mapping. Method Following initial 2D seismic mapping with limited amounts of historical data, additional 1990’s seismic data was obtained from the local government. In 2015 modern processing techniques and innovative field survey reconstructions including crooked line geometry, advanced noise attenuation, manual first break picks, advanced tomography, pre-stack time migration and spectral balancing were then applied to the dataset to delineate earlier identified prospects.

    GW-6 Geological Survey of Japan, AIST Project Report of the CCOP-GSJ/AIST-NAWAPI Groundwater Phase III Meeting 16-18 March 2016, Hanoi, Vietnam COORDINATING COMMITTEE FOR GEOSCIENCE PROGRAMMES IN EAST AND SOUTHEAST ASIA (CCOP) In cooperation with GEOLOGICAL SURVEY OF JAPAN (GSJ), AIST Published by CCOP Technical Secretariat Bangkok, Thailand Youhei Uchida (Chief Editor) PREFACE The CCOP-GSJ/AIST-NAWAPI Groundwater Project Phase III Meeting was held on 16-18 March 2016, in Hanoi, Vietnam. It was attended by nineteen participants from Cambodia, China, Indonesia, Japan, Republic of Korea, Lao PDR, Malaysia, Myanmar, Papua New Guinea, Philippines, Thailand, Vietnam and the CCOP Technical Secretariat. In the meeting, participants confirmed progress of the project from February 2015 to March 2016, and discussed work plan for 2016 by three group discussions. Each CCOP Member Country made a country presentation on the topic, “Recent Groundwater Issues and Their Action Study”. Since the current groundwater problem varies from one CCOP member country to another because of various hydrogeological and geographical settings, each Member Country should share the information for efficient groundwater management in the CCOP regions. This is the publication which was compiled each country report presented in the CCOP-GSJ/AIST-NAWAPI Groundwater Phase III Meeting. These reports have made clear the resent groundwater issues in each Member Country and cooperation policy of Phase III project, and will conduct outcome of the GW Phase III Project. I believe we will be able to have some solutions about not only groundwater management but also energy problem in the CCOP member countries. I am very grateful to the authors for their invaluable contributions and to the Organizations to which the authors belong for their permission to publish those important reports.

The results of the screening and ranking procedure indicate that the Khmer Basin is the most suitable basin, followed by the Kampong Saom and Tonle Sap basins. A quantitative volumetric assessment-based evaluation of CO2 storage capacity is performed on these three suitable basins. The evaluation yields a range in the national CO2 storage capacity of 90 Mt (in structural traps) to 45 Gt (in hydrodynamic traps), representing low- and high-case estimates, respectively. The saline aquifers associated with this storage capacity should be considered prospective storage options as hydrodynamic traps because of containment and capacity issues associated with the structural traps. Eight major point sources of CO2 are identified that have a combined output (estimated for 2008–2024) of 43.1 Mt annually and 82 billion m3 in place, and the potentially-prospective matched storage capacity is assumed.

  • Towards a Quantitative Petrographic Database of Khmer Stone Materials—Koh Ker Style Sculpture*
    Archaeometry 00, 00 (2009) 000–000 doi: 10.1111/j.1475-4754.2009.00475.x TOWARDS A QUANTITATIVE PETROGRAPHIC DATABASE OF KHMER STONE MATERIALS—KOH KER STYLE SCULPTURE* F. CARÒ Department of Scientific Research, The Metropolitan Museum of Art, New York, NY 10028-0198, USA J. G. DOUGLAS Department of Conservation and Scientific Research, Freer Gallery of Art and Arthur M. Sackler Gallery, Smithsonian Institution, Washington, DC 20013-7012, USA and S. IM APSARA Authority, Siem Reap, Cambodia A comprehensive quantitative petrographic database of sandstones used by the Khmers for sculptural purposes would be a helpful tool for archaeologists, museum curators and others interested in pursuing research on early stone usage, geological source and provenance. Towards that end, this paper presents quantitative petrographic analysis of stone materials used in the production of some free-standing sculptures and architectural elements in the Koh Ker style of the 10th century from the collections of the National Museum of Cambodia and The Metropolitan Museum of Art. These materials are compared to samples from the quarry of Thmâ Anlong near the foothills of the Phnom Kulen, Sieam Reap province. Primary and secondary detrital modes and key grain-size parameters are used to identify three sandstone types. The free-standing sculptures are carved from feldspathic arenite and feldspato-lithic to litho-feldspathic arenite. Finely carved lintels are worked from a quartz arenite, which is significantly richer in quartz grains and of a finer grain size. The geo- logical source of the two other lithotypes will have to await detailed geological survey of the Koh Ker area accompanied by petrographic study of selected samples from documented quarries.
