Key findings of the rapid assessment conducted by Tarabang para sa Bicol, Inc. (TABI) during the first week of evacuation:
Evacuees complain of inadequate food supply. As of January 20, in 4 evacuation sites, an average of only 10 kilos of rice was rationed during the first 7 days of the evacuation period.
Inadequate hygiene supplies was also noted.
No income source for families to address non-food needs like transportation, educational needs of students, and household supplies.
Some evacuation centers lack sanitary kitchen facility, bathrooms and toilets.
Overcrowding is common. 20-30 families would usually share 1 regular-sized classroom.
Most evacuation centers have enough drinking water supply. However, domestic water supply is limited. Evacuees with small water containers/pails are not able to store enough water.
Some evacuation centers are not safe from ashfall.
