Rise in soil salinity may cause fall in rice yield: WB

Increase in soil salinity may lead to decline in yield by 15.6 per cent of high-yielding-variety rice and significant changes in the aquatic ecosystems in the Southwest coastal areas of Bangladesh during dry season by 2050, according to recent studies of the World Bank (WB), reports BSS. 
The studies said climate change is likely to increase river salinity leading to shortages of drinking water and irrigation. The changes in river salinity and the availability of freshwater will affect the productivity of many capture fisheries.
It will adversely affect the wild habitats of fresh water fish and giant prawn and in addition, salinity increase may induce a shift in the Sunderbans mangrove forest from Sundari (the single most dominant and important species, with the highest market value) to Gewa and Guran, the WB said. 
"Estimates from the research indicate that Bagerhat, Barguna, Barisal, Bhola, Khulna, Jhalokati, Pirojpur and Satkhira districts will be most adversely affected," it said.
"The region is already facing problems from salinisation and the situation will worsen as climate change continues."
