The department said heavy rain, high tides and upstream flooding since mid-September had caused localised flooding, affecting residents, farmland and infrastructure.
A total of 61.9 hectares of rice have been damaged, including 56.3 hectares suffering losses of 30-70 per cent and 5.6 hectares with damage exceeding 70 per cent.
In Phu Huu Commune, recent rain and high tides caused water to overflow embankments and inundate 18 hectares of fruit trees, including jackfruit, durian, guava and lime.
Local authorities have so far recorded no damage to the flooded orchards and are continuing to monitor water levels and crop conditions.
The commune has mobilised residents to repair sections affected by overflowing water and erosion. It has also established disaster response teams comprising more than 100 commune-level members and 200 members in local villages.
Authorities plan to prioritise repairs and upgrades to vulnerable dykes, embankments, sluices, erosion-control structures and drainage and irrigation systems.
Meanwhile, erosion has been reported along the Tien River in several areas of Cao Lanh Ward, where cracks and subsidence have appeared near homes and infrastructure.
Local authorities have received 27 requests from households seeking resettlement support. Some homes are now just five to 50 metres from the riverbank.
The provincial Department of Agriculture and Environment said 135 erosion sites covering about 17 km had been recorded across Dong Thap, with repairs estimated to cost about VND 330 billion.
One site has received VND 14 billion for repairs, while 75 others need VND 221 billion in works. Another 59 smaller sites will be addressed with local and other funding.
Nguyen Duc Thinh, deputy director of the department, said authorities had been asked to closely monitor rainfall, floods, high tides, water levels and erosion, particularly during peak tides from October to December.
Localities have also been instructed to inspect and reinforce dykes, embankments, sluices and drainage systems, operate flood-control facilities as conditions require and prepare for the evacuation of residents from high-risk areas.
