| A. | Coimbatore |
| B. | Tiruchirapalli |
| C. | Nagapattinam |
| D. | Ramanathapuram |
| Answer» C. Nagapattinam | |
|
Explanation: The Nagapattinam district ofTamil Nadu was badly affected by tsunami in December 2004. It caused great damage to a large number of agricultural lands in the coastal areas, making them sodic. Large tracts of agricultural lands along with the standing crops were destroyed and became unfit for cultivation due to influx of sea water. The district is marked by highly saline condition in which no paddy crop can be cultivated unless the entire soil is flushed with fresh water and gypsum. Besides, aquaculture activity has also led to the dispersion of salt into land area inland making them saline and unfit for any other agricultural purpose. |
