Low water record in the Mekong River

Water levels in the northern Mekong River are at record-low levels, posing a thread to water supply, navigation and irrigation along the stretch of water that is home to about 60 million peoples.  Jeremy Bird, chief executive officer of the Mekong River Commission (MRC) Secretariat, told AFP that in this late February 2010, northen Thailand, northen Laos, and southern China have been affected by the low water, that are lower than the last 20 years records.
Bird said that it is difficult to say whether global warming is responsible but the wet season in Vientiane last year was one of the worst on record, and was followed by much lower than average rain late in 2009 and early this year.
There are eight existing or planned dams on the main stream Mekong in China, which are normally filled during the dry season, with whatever rain that fall during that season.
More information can be get from the Mekong River Commission website at http://www.mrcmekong.org/
Low water level record was continue ocurring, and it was reported by Tran Dinh Thanh Lam, as presented in the Borneo Post March 25,2010, that salinisation threathens crops in the Mekong Delta.  The Mekong Delta is Vietnam's rice bowl, producing half of its annual rice output.  In the last decade, the dry season seems to have been coming earlier each year, and then last longer.  The salt water from South China sea intruded to the Delta during this prolong dry spell, as far as 30 km inland.
Many suspect that dams that built by China, on the Mekong river upstream have contributed to the lower water level downstream.  However, a top official from China is quoted saying they were not to be blame for the water level low record in the waterway, where more water infrastructure are still need to be built.

4. Logical Framework for Integrated River Basin Management

4.1 Introduction The logical framework approach (LFA) was first adopted by U.S. AID in the early 1970s. The framework provides a set of designing tools that, when used creatively, can be used for planning, designing, implementing and evaluating projects (the entire project cycle). The purpose of LFA is to undertake participatory, objectives-oriented planning that spans the life of project or policy work to build stakeholder's team commitment and capacity, through a series of workshops. The technique requires stakeholders to come together in a series of workshops to set priorities and plan for implementation and monitoring. This achieved by structuring the main elements of project in a matrix (the logical framework) which summarizes the project, highlighting logical linkages between intended inputs, planned activities and expected results and records the underlying assumption. See Figure 4.1, for the content of framework matrix and how to read the LFA. 4.2 Steps in Logic

River Basins in Sabah

Figure 1 Rivers and Points Annual Rainfall at Sabah (After Sabah Water Resources Master Plan, 1995) The best source of information about river basins in Sabah is from the "Sabah Water Resources Master Plan", which can be seen at http://www.did.sabah.gov.my/ . The river basins are can be grouped as those that discharging the flow to the west coast, north coast, and to the east coast. Some rivers that go to west coast are: Sg. Mayog/Babogon Sg. Papar Sg. Padas Some rivers that go to the north coast are: Sg. Bandau Sg. Bangan/Kinorom Sg. Bengkoko/Pitas Some rivers that go to the east coast are: Sg. Liwagu Sg. Kinabatangan Sg. Tawau Sg. Merotai Besar The Figure 1 shows the points annual rainfalls and rivers in Sabah.
