Answer: Preserving wetland and coastal mangrove habitats
Step-by-step explanation:
The wetland must be preserved using physical barriers and planting trees around wetland this will protect the outflow of water which is expected during rain into the land. Also the maintained of mangrove habitats is necessary in flood prone coastal areas. The mangrove trees hold on the soil and sediments on the coastal areas further prevent the erosion. The root, canopy of the trees and the tree trunks can prevent the high speed waves generated during storm and thus help in flooding the urban areas.
