Asiancorrespondent – THE millions of people who depend on the Mekong River for survival are at risk due to the twin threats of climate change and hydroelectric power plants. While the latter is often seen as part of the solution to the former, in this case hydroelectricity may, in fact, be a more urgent threat.

vietnamnews – CẦN THƠ (VNS) — Aside from natural forces like climate change, countries’ actions have worsened the drought and salinity in Việt Nam’s Mekong Delta. Tiếp tục đọc “Dams upriver exacerbate drought in Mekong Delta”
asia.nikkei.com – The green revolution has done wonders for Asia. Yields for most crops, particularly the region’s main staple of rice, have doubled over recent decades. In the Lower Mekong Delta, considered to be Asia’s rice bowl, the new technologies and crop strains that the green revolution brought were a big success.

Rice production in the Lower Mekong countries of Cambodia, Laos, Myanmar and Vietnam soared 68% between 1980 and 1995. During the same period, average yields more than doubled from their levels in the 1960s to about 3.5 tons per hectare. Total land area planted with rice also increased by around 25% to 16.3 million hectares between 1996 and 2005.
The slower trends in yield and production growth were not unique to the Lower Mekong. They also applied to the rest of Asia for various reasons. Chief among them is that green revolution technologies, particularly new rice seed varieties, had become exhausted. Poor land and water quality were also culprits in the drop-off, along with inadequate farm management practices and the rapid conversion of farmland to non-agricultural use. Eroding profit margins due to a decline in the price of rice on global markets exacted a heavy toll as well.
Low productivity
There is reason for alarm at the change. Agriculture still provides 10% of Asia’s value-added output and is an important source of employment as about 45% of jobs in Asia are in rural areas. With declining yields and production, this means that productivity, the value of output per worker, will decline further. Tiếp tục đọc “Reinvigorating agricultural productivity in the Lower Mekong”
