Ban Samkha is located in a valley where nearby mountains are the village's main source of water. Landslides occur naturally in these mountains but deforestation has worsen the situation in recent years. Whenever there is heavy rainfall, the village is considered at risk.

Now that children have constant access to the internet via the XOs, they have created a strategy that encourages the children to act as weather guardians. Children will help monitor the rainfall level and alert the village head when it reaches dangerous levels (currently rainfall greater than 80mm/day is considered dangerous.) The village head will then alert the villagers.
