Different Disasters and their Impact:

Animal Attacks


The number of events of animal attacks has increased towards the latter period of the 34 year timeline under consideration. This is due to better data collection methods in the recent years. Spatially, animal attacks are clustered around the centre of the island. People affected by animal attack have increased in the latter years, but has gradually declined. However, unlike people affected, deaths appear to be fluctuating within the last ten years. Damage to houses also takes a similar pattern as people affected.

Spatially, all three factors follow a similar trend with most losses seen towards the centre of the island, while districts like Colombo, Batticaloa, Mannar, and Mullativu are least affected. Agricultural loss takes a different time trend with most losses seen in the middle of the time line. Further, districts like Anuradhapura, Moneragala and Badulla have the highest agricultural loss and districts clustered around the Northern and South Western parts of the island have experienced low levels of agricultural loss.

Flooding (including Riverine Floods, Flash floods, Urban flood and Heavy rain)

The incidence of flooding seems to be most frequent in the latter years, with the most flooding occurring in the year 2006. Further, the floods in Sri Lanka are most likely to occur in the months of May in the first cycle and in December in the second cycle. With respect to spatial distribution floods are most frequent in the districts of Jaffna, Kalutara, Rathnapura, Gampaha and Ampara.

People have become increasingly affected by floods with the highest number recorded in 2008. Further, people located in the districts of Gampaha, Kalutara, Batticaloa, Rathnapura and Ampara have been most affected by floods. However, the occurrence of deaths due to floods is quite low except for the year 2003 where it reached nearly 180 persons. Destruction and damage to houses and buildings also appear to follow a similar pattern with most damage occurring in the districts of Rathnapura, Ampara, Batticaloa, Polonnaruwa, and Jaffna. Damage to paddy has taken place mostly in the earlier years with the highest impact recorded in 1984, while spatially the highest damage has incurred in the districts of Kurunegala, Polonnaruwa, Ampara and Batticaloa.In some instances with respect to DS divisions, some impacts have been reflected as low, which can be attributed to the limited availability of disaggregated data at this level.
