From the question, I found that:
The natural disaster in Mukdahan province is drought that maybe occurs once a year or twice a year.
When Mukdahan province has drought that leads to wildfire and dry river. Moreover, drought leads to famine because the environment doesn't have food to sustain all life.
In Mukdahan province, the farming is about 30%.
In charge of blocking the natural disaster is a Department of Disaster Prevention and Mitigation Ministry of the Interior.
