Dadaab's residents. Although they are typically required to remain in the camp, residents often have to venture out in search of firewood and water. They are thus obliged to travel farther due to deforestation in nearby areas. This leaves women and girls vulnerable to violence as they journey to and from the complex. In 2006, flooding severely affected the region. More than 2,000 homes at the Ifo camp were destroyed, forcing the relocation of more than 10,000 refugees. The sole access road to the camp and to the town was also cut off by the floods, impeding the delivery of essential supplies. Humanitarian agencies present in the area worked together to bring vital goods to the area. In 2011, a drought in Eastern Africa caused a dramatic surge in the camps' population, placing greater strain on resources. By February 2012, aid agencies had shifted their emphasis to recovery efforts, including digging irrigation canals and distributing plant seeds. Long-term strategies by national governments in conjunction with development agencies are believed to offer the most sustainable results. Rainfall had also surpassed expectations and rivers were flowing again, improving the prospects of a good harvest in early 2012. Security Refugees at the UNHCR centre are not protected by the Government of Kenya (GOK). This has contributed to dangerous living conditions and outbreaks of violence. Because they are not protected under the law and are unable to possess a Kenyan national identification card, refugees are constantly at risk for arrest. Additionally, the Kenyan government screens ethnic Somalis and Ethiopians separately from other residents due to their different physical characteristics. A special category in local police documents is earmarked for "Kenyan-Somalis". While all refugees at the camp are at risk of violence, the UNHCR and CARE have identified women and children as being particularly vulnerable. They have created a department called 'Vulnerable Women and Children' (VWC) to tackle the issues surrounding violence against these populations. As of August 2015, 60% of Dadaab's total population is under the age of 18, and there are equal numbers of men and women, so women and children make up a significant portion of the camps' demographics. Specifically, the VWC department has identified orphans, widows, divorcees, rape victims and the disabled as the most vulnerable among all women and children. They offer counselling, additional food rations and supplies, and advice on how to earn an income and be financially self-sufficient.
