Climate

When is the dry season, these areas remain waterlogged soils. And sometimes the moisture evaporates from reservoirs so that the river becomes shallow. It gives more inconveniences. The biggest problem of this region is tropical malaria. In a single year from this disease worldwide kills about 2 million people.
