About400,000 ha of land under agricultural production in the provinces havebeen affected by the prolonged drought and salt water infiltration,according to figures from the Sai Gon Giai Phong (Liberated Sai Gon)newspaper.
The salinity in the early dry season at estuariesin the Mekong Delta was one to 10g per litre (0.1 to 1 percent) higherthan the same period last year.
In Ben Tre province, water with0.4 percent salinity has infiltrated 50 km deep inland, raising salinitylevels to 0.2 percent in canals in fields along estuaries and thecoast.
The acute drought has damaged thousands of hectares of rice fields and other crops in the province.
Ifthe saltwater enters Ba Lai River, which serves as a reservoir forfreshwater for thousands of families, it could seriously affectresidents of Ben Tre City and Chau Thanh district in the province.
As a precautionary measure, authorities in the province have closed 64 culverts and reinforced embankments along rivers.
They are also monitoring the salinity of water in the river and irrigated rice fields.
