AI : Funan Techo Canal

 

Flows of rivers throughout the world have been altered by population and economic growth and accompanying water resources development. River flow characteristics are changed by construction of dams and other facilities to control floods, generate hydroelectric energy, and provide reliable water supplies, diversions for agricultural, municipal, and industrial needs, and return flows from surface and groundwater supplies. Impacts on hydrology and water availability associated with climate change due to global warming are also of major concern in hydrologic science and water management.

Discussing F.T.Canal

In response to information about the Funan Techo canal project (also known as the Funan - Techo canal project) of Cambodia that will upset the Western ecosystem; could take away 50% of the water from the Mekong River;... Professor - Doctor, People's Teacher Vo Tong Xuan is a scientist in the field of agriculture - said that, initially, this is not too much of a concern. as reported by some press recently. However, we also need to wait for specific data to evaluate.

The Flow of the Mekong

The  Mekong river flows 4800 km from  Tibet through China, Myanmar, Lao PDR, Thailand,Cambodia, the Vietnam delta, and into the South China Sea, draining an area of 795,000 sq. km.   It is currenlty one of the least modified large rivers and the second most bio-diverse river in the world after the Amazon.

Dams's impacts on Mekong

 

China completed its first mainstream hydropower dam on the Mekong, the Manwan dam in Yunnan province, in 1995, and has since planned and built 10 more. Eleven hydropower dams are in various stages of planning and construction in Laos and Cambodia on the mainstream of the Mekong river, along with hundreds of dams on its tributaries.

Mekong River Hydropower

The estimated hydropower potential of Mekong River Basin about 58,930 Megawatts (MW). As of February 2024, there are an estimated 167 Hydropower Plants (HPPs) in the Mekong, with a combined installed capacity of some 36,376.3 MW. An additional 20 HPPs are currently under construction and at various stages of completion. These have a combined installed capacity of an additional 4,535.5 MW.

The Mekong Delta

 

The Mekong Delta, also known as the Western Region or South-western region, is the region in southwestern Vietnam where the Mekong River approaches and empties into the sea through a network of distributaries. The Mekong delta region encompasses a large portion of south-western Vietnam of over 40,500 km2. The size of the area covered by water depends on the season. Its wet coastal geography makes it an important source of agriculture and aquaculture for the country.

Mekong Research Network

 

The Sustainable Mekong Research Network (SUMERNET) is a network of organizations committed to the sustainable development of the Greater Mekong Region. Launched in 2005, SUMERNET supports policy-relevant research and outreach activities to inform and engage policy-makers, planners and stakeholders. Within this context, it pursues an evolving agenda in response to questions and policy issues that arise in the region. Current research themes are climate-compatible development, regional economic integration, and ecosystem services and local development. The network works on a range of issues including natural ecosystems governance, floods and natural disasters, climate change and adaptation, and transboundary resource flows.

Mekong River Commission

The Mekong River Commission (MRC) is an "...inter-governmental organisation that works directly with the governments of Cambodia, Laos, Thailand, and Vietnam to jointly manage the shared water resources and the sustainable development of the Mekong River". Its mission is "To promote and coordinate sustainable management and development of water and related resources for the countries' mutual benefit and the people's well-being".

Greater Mekong Subregion

 

The Greater Mekong Subregion, (GMS) or just Greater Mekong, is a trans-national region of the Mekong River basin in Southeast Asia. The region is home to more than 300 million people. It came into being with the launch of a development program in 1992 by the Asian Development Bank that brought together the six Asian countries of Cambodia, China (specifically Yunnan Province and the Guangxi Zhuang Autonomous Region), Laos, Myanmar (Burma), Thailand, and Vietnam.

The Mekong River


The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth-longest river and the third-longest in Asia with an estimated length of 4,909 km and a drainage area of 795,000 km2, discharging 475 km3 of water annually. From its headwaters in the Tibetan Plateau, the river runs through Southwest China (where it is officially called the Lancang River), Myanmar, Laos, Thailand, Cambodia, and southern Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between Tibet and Southeast Asia. The construction of hydroelectric dams along the Mekong in the 2000s through the 2020s has caused serious problems for the river's ecosystem, including the exacerbation of drought.

Carbon dioxide removal

 

Carbon dioxide removal (CDR), also known as carbon removal, greenhouse gas removal (GGR) or negative emissions, is a process in which carbon dioxide gas (CO2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products. 

Waste management

Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.
