Developmental activities can trigger natural disasters over longer periods of time. These include:

• Development of port towns on the shores of the country make the people susceptible to disasters like cyclones and hurricanes.

• Construction on slopes of the young mountains can trigger landslides by loosening the soil on the slopes.

• Agriculture and extensive ploughing on slopes can also cause landslides

• Massive construction of roads is associated with floods and water logging, due to lack of percolation of water into the earth.
