The Sekong flows through southern Laos and into northeastern Cambodia and the Sesan and Srepok flow through northeastern Cambodia. The three rivers converge just before flowing into the Mekong at Stung Treng in Cambodia. More than 4,300 km of rivers make up the 3S system. The Sekong mainstream and tributaries total 1,917 km, the Sesan’s 706 km, and the Srepok’s 1,687 km. The 3S have seen extensive hydropower construction since the 1980s, primarily in the highlands within Viet Nam. Hydropower dams have altered flow patterns, sediment load, and connectivity. A number of hydropower dams planned for the basin would further negatively impact the ecosystem, with implications for food security and sea level rise adaptation downstream. The Sekong Basin, which has remained without a dam on the mainstem, provides the best opportunity to maintain these values while providing adequate energy through an energy mix appropriate to the region. The land and water of the 3S basin play a critical role in providing environmental flows and ecosystem services to the Tonle Sap in Cambodia and the Mekong Delta in Viet Nam. More than 20% of the Mekong’s water comes from the 3S. Most of the basin receives over 2,700 mm/year of rainfall, most of which falls during the summer monsoon in June to September. Before construction of the Lower Sesan 2 (LS2) dam, the 3S contributed 15-20 million tons of sediment/year to the Mekong’s sediment budget or 9.3-12.5% of the total. Sediment and nutrient flows are critical for agricultural production

A study was conducted in four villages in Attapeu Province, Lao PDR in 2002 to determine malaria endemicity. The study villages were Mixay, Beng Phoukham, Phou Vong and Pier Geo. Mass blood surveys were conducted in May, August, and October. Finger prick blood was collected for thick and thin blood film as well as for dipstick. The slide positivity rate was highest in Phou Hom in October (41.7%). Plasmodium falciparum was the dominant species comprising more than 80% of the cases. As a whole, the distribution of malaria was similar among males and females. Children below 15 years accounted for a large percentage of the cases. The sensitivity of the optimal dipstick was 62.36 and the specificity was 61.7. Microscopy was taken as the gold standard. Anopheles dirus was found to be the main vector and the vectorial capacity correlated well with the cases. INTRODUCTION entomological and blood examination 3 times during the year.

  • The Sesan, Srepok, and Sekong (3S) Rivers Dam Developments
    <Nature and Our Future: The Mekong Basin and Japan> 2-4. Cross-Border Environmental Issues: The Sesan, Srepok, and Sekong (3S) Rivers Dam Developments Overview of the Sesan, Srepok, and Sekong Rivers The Sesan, Srepok, and Sekong Rivers (collectively known as the 3S Rivers) comprise the largest water system made of Mekong River tributaries. The 3S are all international rivers that flow into northeastern Cambodia from their sources in the plateaus of central Vietnam and the Phu Luang mountain range in Laos. The downstream region is made up of Cambodia’s northeastern provinces of Ratanakiri, Steung Treng, and Mondulkiri, where many indigenous and ethnic peoples live with differing livelihoods, languages and cultures. There are approximately 70,000 people living along the three rivers in some 127 villages, and their livelihoods depend on natural river resources. This region is also known for its rich natural resources and biodiversity, and about 40% of Cambodia’s natural forests are in Ratanakiri and Mondulkiri Map: 3S River basin Provinces. The natural resources of the 3S river basin are very important, not just from the perspective of environmental conservation, but for ensuring food security and livelihood for people living in the region who depend on natural resources. Transboundary Hydropower Dam Impacts Because the three rivers are international waterways, upstream development is having a large impact on nature and people in Cambodia. In 1993, construction of the Yali Falls Dam in Vietnam began as the first hydropower dam project in the Sesan River Basin, at a point just 80 km within the Cambodia-Vietnam border. In October 1996, there was flooding of Cambodian villages, the cause of which is attributed to a broken water diversion dam when the Yali Falls Dam was under construction.

A study was carried out in four malaria-endemic villages in Attapeu Province, in the southern region of Lao PDR. All-night human landing collections were carried out in May, August, and October 2002, to determine malaria vectors. At the same time, mass blood surveys were also carried out in the same villages. Anopheles dirus was the predominant species in three of the study villages. Sporozoites were found only in An. drius from Phou Hom. However, in Beng Phoukham, An. dirus was positive for oocysts. The distribution of malaria cases was highest in Phou Hom and this correlated well with the vectorial capacity of An. dirus. The risk for infection from An. dirus was also high, at 0.99.

  • Listening to Women Fishers on the Sekong River: Fostering Resilience in Village Fishery Co-Management
    Listening to Women Fishers on the Sekong River: Fostering Resilience in Village Fishery Co-Management Charlotte Moser Abstract The accelerated economic development of landlocked Laos, combined with extreme climate variables, points to dramatic transformations in subsistence fisheries on its rivers. In the country’s first Fisheries Law, adopted in 2009, co-management of village fisheries is required as a way to promote sustainable development at a local level. The co-management model, however, does not stipulate participation by women fishers, important stakeholders who make up almost one-half of all Lao fishers and whose work contributes directly to family nutrition and well-being. Based on fieldwork conducted in fishing villages on the Sekong River in southern Laos in 2013, this paper takes an ecosystems approach to discuss how the country can build resilience and social cohesion into fisheries by incorporating women and their knowledge into village fishery management. In the process, the health of river ecosystems and food security will improve, while women fishers will acquire new skills to help them avoid ‘poverty traps.’ Introduction The concept of resilience is central to effective adaptive management of ecosystems. Developed by ecologist C.S. “Buzz” Holling in the 1970s as a theory for managing complex ecosystems, resilience theory suggests that an ecosystem is resilient if it has the ability to remain cohesive during periods of extreme perturbations or what are called ‘shocks’ (Holling 1973). Rather than “bouncing back” to a former equilibrium, an ecosystem is resilient if it can absorb changes in internal and external variables and still persist, albeit in a somewhat different yet robust form.

These fishes attain a maximum body weight of 30 kg. Global population declines highlight the need for more information ≥ about megafishes’ conservation status to inform management and conservation. The northern Cambodian Mekong River and its major tributaries are considered one of the last refugia for Mekong megafishes. We collected data on population abundance and body size trends for eight megafishes in this region to better understand their conservation statuses. Data were collected in June 2018 using a local ecological knowledge survey of 96 fishers in 12 villages. Fishers reported that, over 20 years, most megafishes changed from common to uncommon, rare, or locally extirpated. The most common and rarest species had mean last capture dates of 4.5 and 95 months before the survey, respectively. All species had declined greatly in body size.

Regardless of the last cholera epidemic in Attapeu province, Lao PDR in the year ῍῕῕῕, the local peoples’ awareness of cholera was remarkably low, as demonstrated by the knowledge survey on diarrheal diseases performed in the province in ῎ῌῌῒ. In the case study material, derived from continuous field observations on malaria among permanent residents in relocated villages in Sanxay district from ῎ῌῌῐ to ῎ῌῌ῔, the infection rate among febrile cases was as high as ῐῑ῏ in the early resettlement period, while it was proved that the rate fell later to ῍ ῕ῌ῍ῐ῏. Judging from the environmental condition of this settlement area, this paper makes clear the persistent threat of malaria. Furthermore, among the villagers, hookworm infection was highly prevalent. However, liver fluke infections were scarce and no ascariasis was found from parasitic stool examination in ῎ῌῌΐ. Water quality analysis of the water sources resulted in remarkably safe water from tube wells from ῎ῌῌ῏ to ῎ῌῌ῔.
