Rice Production in Tonle Sap Floodplains in Response to Anthropogenic Changes in Hydrology, Climate, and Agronomic Practices
Rice Production in Tonle Sap Floodplains in Response to Anthropogenic Changes in Hydrology, Climate, and Agronomic Practices Manuel P. Marcaida III A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science University of Washington 2020 Committee: Soo-Hyung Kim Faisal Hossain Rebecca Neumann Program Authorized to Offer Degree: Environmental and Forest Sciences © Copyright 2020 Manuel P. Marcaida III University of Washington Abstract Rice Production in Tonle Sap Floodplains in Response to Anthropogenic Changes in Hydrology, Climate, and Agronomic Practices Manuel P. Marcaida III Chair of the Supervisory Committee: Soo-Hyung Kim Environmental and Forest Sciences Rice is the most important agricultural commodity in Cambodia as food and source of livelihood. Majority of rice production happens around the Tonle Sap floodplains sustained by the sediment- rich flood from the Mekong River. With the increased construction of hydropower dams upstream, the natural flow of water, organic materials, and fish species delivered to the Tonle Sap Lake is altered. While these changes open up more areas for rice cultivation especially during the dry season, the quality of the sediments is expected to decline. Moreover, drought is becoming a frequent occurrence and temperature is increasing. This study examined how the rice cultivation in the Tonle Sap floodplains is impacted by the hydrological changes, climate, and agronomic practices. Specifically, we 1) assessed the impacts of the increasing presence of dams on the timing and location of rice cropping, and 2) tested and applied an ecophysiological crop model to simulate the effect of changes in hydrology, agronomic practices, and increasing temperature on rice production in Tonle Sap floodplains. -
3. the Power Sector 3.1 Laws and Regulations
Final Report Chapter 3 The Power Sector 3. THE POWER SECTOR 3.1 LAWS AND REGULATIONS The legal and regulatory framework of the power sector of Cambodia is governed by the following laws: Electricity Law Other applicable laws, polices and regulations 3.1.1 Electricity Law The power sector of Cambodia is administered and managed under the Electricity Law which was enacted in February 2001. The Law provides a policy framework for the development of a largely unbundled sector, with substantial private sector participation in generation and distribution on a competitive basis. The Law aims at establishing: 1) the principles for operations in the electric power industry; 2) favourable conditions for investment and commercial operation; 3) the basis for the regulation of service provision; 4) the principles for protection of consumers interests to receive reliable services at reasonable cost; promotion of private ownership of the facilities; and establishment of competition. 5) the principles for granting rights and enforcing obligations; and 6) the Electricity Authority of Cambodia (EAC) for regulating the electricity services. The Law has two key objectives: 1) establishing an independent regulatory body, EAC; and 2) liberalizing generation and distribution functions to private sectors. Two functions of policy making and regulation are clearly separated as shown in Figure 3.1.1. The Ministry of Industry, Mines and Energy (MIME) is responsible for policy making, including drafting laws, declaring policies, formulating plans, deciding on investments, etc. EAC is responsible for regulatory functions, including licensing service providers, approving tariffs, setting and enforcing performance standards, settling disputes, etc. The liberalization and deregulation of the sector has stimulated the private sector with resulting proliferation of independent power producers (IPP) and rural electricity enterprises (REE) in addition to the traditional public utility, the Electricite du Cambodge (EDC). -

Tonle Sap Ecosystem Water Quality Index Development and Fish Production
Sustainable Development and Planning III 901 Tonle Sap ecosystem water quality index development and fish production N. T. H. Yen1, K. Sunda1, S. Oishi1 & K. Ikejima2 1Department of Civil Engineering, University of Yamanashi, Japan 2Asian Institute of Technology, Bangkok, Thailand Abstract The Tonle Sap ecosystem of Cambodia is situated in the lower part of the Mekong River basin (MRB), the TS ecosystem water environment is influenced by 181,035 km2 of its catchments and water inflow from 4000 km in length of the upper Mekong River. The water quality index (WQI) was developed based on seven environmental chemical factors of DO, NO3+NH4, TOTP, TSS, temperature, pH and conductivity at Kampong Luong monitoring station during the period 1995 - 2002. On PCA, among 15 candidate parameters, the six most variation parameters of ‘concentration of TSS mg l-1’, ‘temperature C degree’, ‘conductivity mS m-1’, ‘ratio between N and P’, ‘average monthly variation of NO3+NH4N’, ‘average monthly variation of pH’, were identified and selected to constitute the WQI. Each parameter was scored as 1, 3 and 5 and narrated, in order, as poor, fair and good conditions. The yearly WQI score was calculated from these six parameter scores in the relative year. The WQI showed that the highest score of 4.3 was in 1996, while the lowest scores were of 1.3 and 1.0 in 2002 and 1998. Importantly, the WQI was significantly (P<0.05) correlated with the ‘dai’ fish catch (r2 = 0.858) and the fish biological group 4 (r-species) (r2 = 0.75) during the period 1995-2002 indicating that the index was sensitive to reflect the relation between water quality condition and fish production. -

Journal of Soil and Water Conservation The Tonle Sap River flows 147 km (91 mi) southeast from Tonle Sap Lake to meet during the dry season with the Mekong River near Phnom Penh, the capital of Cambodia. In the monsoon season (May to October), the Mekong River floods and causes the water to back up into the Tonle Sap River, reversing its flow (Carling 2009). This wet season flow reversal brings Mekong River sediments, nutrients, and an abundance of fish into the lake and 73(3):60A-66A enlarges the lake into its floodplain 20 to ers produce more than 80% of Southeast the Mekong River and Cambodia’s Great 40 km (12 to 25 mi). -

The Critical Role of the Mekong and Tonle Sap Corridor for Tonle Sap Lake Ecology and the Important Role of the Waterway Wetland in Cambodia
Page 1 of 10 The Critical Role of the Mekong and Tonle Sap Corridor for Tonle Sap Lake ecology and the important Role of the Waterway Wetland in Cambodia by Touch Seang Tana 1. Introduction For almost 20 years involving in the fisheries sector, especially the inland fisheries, a thousand doubts rise up in my mind at every step of approach on how the nature cerates this critical inland water system and its tremendous resources. Why the Tonle Sap Lake reputed as a larges fisheries productive freshwater systems for many millennia (Chu Ta Kwan, 1329, Mohout, 1857-9, Vincent, 1860-1, Petiole, 1911). What this lake was before the above period as Rainboth, 1996 quoted in his Zoogeography book that the freshwater Tonle Sap Lake aged about five thousand years and the present Mekong and Tonle Sap River were only two thousand years age. A French researcher, August Pavie,1898 was well explained in his Researcher sur L'Histoire du Camboge, du Laos et du Siam, indicated that the whole central plain of Cambodia was a marine bay and the Mekong River reached this bay at somewhere near the entrance of the present Tonle Sap Lake (see Figure1). This latter information was well explored by geological and archeological works on textile soils and fossiles located 12 meters beneath in Samrong Sen (northeastern Kampong Chhnang town), which represented the prehistoric human settlement of this region. Before the lake connected to the Mekong and Tonle Sap Rivers, neither data nor information proving the biological richness of the Tonle Sap Lake were available. -
