10. Pollution of environment from agro chemicals, solid waste disposal and<br />

sewage<br />

241. Coastal water bodies are currently polluted through excessive use of agro chemicals<br />

by farmers, siltation due to agricultural and non agricultural soil erosion and leaching of<br />

polluting chemicals from solid waste dumping. Once solid waste management is streamlined,<br />

as explained above, the significant remaining contributors to pollution are the agriculture<br />

sector and urban sewage.<br />

242. The Department of Agriculture is implementing an intensive home garden<br />

development program in the SAM planning area based on organic farming. This program<br />

should reduce the soil erosion from poor agricultural practices and also minimise the<br />

excessive use of agro chemicals. Discussions with Assistant Director-Kantalai revealed that<br />

Department of Agriculture is implementing an awareness program to apply fertilizer in the<br />

right quantity at the right time. Application of Triple Super Phosphate (TSP) fertilizer as top<br />

dressing for paddy instead of basal application is an issue and department is taking proper<br />

action on this.<br />

11. Salt water intrusion to paddy fields<br />

243. This is an issue in paddy cultivation around the north western section of<br />

Thampalagamam bay but only to a limited extent. NECCDEP has constructed salt water<br />

intrusion prevention bunds in this area. However, salt water intrusion is not recorded as an<br />

issue from other parts of the buffer zone. There may be few inundations in the Ralkuli estuary<br />

but this is a temporary issue.<br />

12. Coastal or Sea erosion<br />

244. Coastal erosion is be<strong>com</strong>ing an important issue for management of shorelines and<br />

lagoon ecosystems. Coastal erosion is severe in Kadatkaraichchenai, Salli and Kinniya<br />

areas. Field visits revealed that sea erosion is a severe issue along A-15 road from Kinniya<br />

to Mahaweli River estuary. A-15 road has realigned at least 5 times during the past due to<br />

sea erosion. Figure V.2 shows the severe sea erosion between Kinniya and Upparu estuary.<br />

As a precaution, sections of the A-15 road have been shifted to inland areas under the A-15<br />

road rehabilitation program. It is essential to look into this issue. Discussions with RDA<br />

revealed that they are aware of the issue and take precautionary actions in the road<br />

construction process. The tsunami damaged the natural and man-made barriers and there<br />

are no interventions to control the erosion at present.<br />
