  • An analysis of the complex relationship between demographic changes and impacts on the natural-resource base confirms that resource exploitation is occurring not only to meet growing domestic needs but also for other vested interests. Population, together with other major drivers, such as institutions, markets, and technology, will have a very strong bearing on the way in which the rich resources of the Mekong River Basin are developed and distributed in the present and future.

  • Mekong River, the 11th largest river in the world, is the main water source for irrigation, fishery, and domestic use… In short, the living of the whole population in the Mekong Delta (MD) is depending and will be depended on this resource. The MD of Vietnam is located at the most downstream part of the Mekong river basin. With a population of 17 million inhabitants living in 4 million hectares of land, the MD has great potentials for agricultural production. The MD is the most important agricultural production region for the whole country.

  • The fishery of the Mekong River is one of the largest and most significant in the world, and most of the production is based on migratory river fishes. An earlier report provided an overview of the general patterns of fish migrations and their significance for management. This complementary report provides more detailed information on 40 key species which are significant in the Mekong River fishery. For each species we provide notes on distribution, feeding, size, population structure, critical habitats, life cycle and its importance in fisheries.

  • The Mekong River Delta (MD), the most downstream part of the Mekong river, is known as the biggest "rice bowl" of Vietnam. Currently, 2.4 million ha are used for agriculture. During the rainy season part of the Delta is flooded. Along the 600 kmcoast, the sea tide strongly influences the water quality by sea water intrusion. In addition, an area of 2-million ha is covered by acid sulfate soils. Also, the MD is very densely populated with intense associated water pollution.

  • The Mekong River Delta (MD) in Vietnam has an area of 4 million hectares. The economical production in this region is highly dependent on water from the river and canal system. More than two-third of 17 million inhabitants of the MD live in rural areas and depend totally on the water resources for rice, upland crop irrigation, aquaculture of fish and shrimp, domestic drinking and industrial water supply and for transportation on rivers and canals

  • The Mekong River is one of the few great, largely unregulated rivers of the world. Its Delta is both agriculturally and aquatically highly productive and a major contributor to the region’s food production and export earnings. Water and land issues of the Delta must be considered as integral with those of the Mekong Basin as a whole. A majority of the Mekong Basin’s 60 million, ethnically diverse peoples rely on the River’s aquatic resources and rice production for their subsistence. For many, 40 to 60% of their protein intake is from fish from the Mekong.

  • The Mekong delta (MD), the most downstream part of the Mekong river (See figure 1), is known as the biggest "rice bowl" of Vietnam. The Delta has a population of 17 million inhabitants living in 4 million hectares of land. All the people living in the Delta have to depend totally on the water resources, mainly the surface water, for domestic drinking, crop irrigating, fish-shrimp raising, goods transporating and industrial producing.

  • Abstract. In this study, we assessed the impact of sea level rise, one of the most ascertained consequences of global climate change, for water levels in the Vietnamese Mekong Delta (VMD). We used a hydraulic model to compute water levels from August to November – when flooding is presently critical – under sea level rise scenarios of 20 cm (= 20) and 45

  • Water quality is one of the key factors affecting the environmental health of the Mekong river system. As the livelihoods of most of the 60 million people who live in the Lower Mekong Basin (LMB) wholly or partly depend on aquatic resources, the environmental health of the river is a major concern to the governments of the countries in the basin. In 1985, the Mekong River Commission (MRC) established the Water Quality Monitoring Network (WQMN) to provide an ongoing record of the water quality of the river, its major tributaries, and the Mekong Delta.

  • The Mekong River Delta in Vietnam can be considered as a large tropical wetland, in which two typical eco-forest wetlands can be distinguished: the inland Melaleuca forest wetlands and the coastal mangrove forest wetlands. Their main functions are the provision of forest commodities, the regulation of the water balance and biodiversity conservation. However as elsewhere under human pressure their existence is under the threat of forest fires and deforestation. Their protection requires the implementation of a multi-level national or sub-national planning policy.

  • The Mekong river is ranked as the tenth one in the list of the largest rivers in the world and is longest river in southeastern Asia. From its source in Tibet, the river flows to the South China Sea through Yunnan, China, forms the border partly between Burma and Laos and most of the border between Laos and Thailand, then the main stream goes into Cambodia and finally it flows across southern Vietnam to the sea (figure 1).

  • An outstanding feature of the lower Mekong region is the dynamic energy of its natural systems and how intimately tied most of the population is to that seasonal force. Productivity in agriculture and fisheries, for example, depends on annual floodplain inundation and nutrient dispersal. The immense scale and impact of this natural cycle is well illustrated in the annual flooding of Tonle Sap Lake in Cambodia and the Mekong River Delta which it shares with Vietnam.

  • Each rainy season, the Mekong River Delta receives flood flow from the upstream of the Mekong River. Floods in the Mekong Region are beneficial for agriculture and fisheries productivity, but high floods also result in the losses of life and property. Records of flood losses show that children were at high risk. The “Living together with floods” strategy of the government and the people should also help prevent children from drowning.

  • The Songkhram River is a large tributary of the Mekong River which runs through the northern part of northeast Thailand. The river system supports a large but previously undescribed capture fi shery. This survey covered villages within the lower one-third of the Songkhram River Basin (SRB), where extensive wetlands are associated with the most productive fi sheries.

  • Reduced whole rice grain yield due to cracking is one of the major issues that directly reduce income and availability of staple food to the farmers in the Mekong River Delta. The cracking or partial fissuring of rice kernels may occur right in the paddy field due to incorrect harvesting time/practice, improper post-harvest drying conditions and inappropriate milling operations. This project aims to improve the quality and value of the rice, through an integrated approach which encompasses farmers, millers, service providers and extension workers and education institution....

  • This study grew out of a request from the Technical Advisory Body for Fisheries Management (TAB) conveyed to us by Wolf Hartman of MRC. We are grateful for the opportunity the body has given us to think about fisheries in the Mekong basin in the context of local and broader ideas about the role for livelihoods approaches in fisheries management and for Wolf’s encouragement and support. Carrying out the research on which this document is based was supported by many people it also links closely with related work on livelihoods....

  • Vietnam is embarking on a path towards a knowledge-based economy in which the emergence of knowledge clusters in Ho Chi Minh City and the Mekong Delta are playing a decisive role. As our paper suggests, clustering appears to have a positive effect not only on the increase of knowledge output, but also on the economic growth of these regions. Using a GIS-based mapping method, we can identify two major knowledge clusters – Ho Chi Minh City and Can Tho City.
