T he government officially announced the launch of military operation against the militants in Swat, in addition to Buner and Dir districts in the last week of April. The launch of the military operation resulted in mass migration of the affected population to other districts in search of safety and security. 80% of the population of Buner district left the area. The total number of the Internally Displaced Persons (IDPs) exceeded 3 million according to UNHCR/ national media reports. The government initially established three camps in Swabi and two camps in Mardan district. The government provided tents for shelter, cooked food and some daily use items to the families residing in the camps. The residents of the camps were having difficulty in access to clean drinking water, sanitation and facing the hot weather in the tents. The scorching heat has been the biggest problem the residents were facing in camps, especially women and children. Most of the displaced families (more than 70%) have opted to reside with the host communities instead of residing in the camps established by the government. The influx of the displaced families has been noted to be the highest in Swabi district followed by Mardan district. This catastrophe faced was unprecedented in the history of North West Frontier Province (NWFP). The hot weather in the district Mardan, Charsada, Peshawar and Swabi where the displaced families were taking refuge added up additional stress on women and children who would be forced to stay in small places or tents during the hot summer days. The hospitality spirit shown by the host community needs to be saluted as it played a vital role in reducing the impact of the disaster because the government was least prepared for the outcomes of the military operation. The scale of the disaster would have been much higher if the host communities were not supportive to the displaced families.
