The first is deliberately and directly‚ through floodplain restoration‚ construction of dams and channel rehabilitation and all of these have fairly obvious positive effects on reducing flood risk. However it is when humans indirectly affect the flood risk‚ through deforestation‚ land use change and climate change (which all have a negative

It starts from learning the causes of the disaster and stop or avoid to do those activities. For example use of woods and not replenishing of lost woods. Uprooting of Plants is also linked with mining activities and building of Dams. We know we cannot stop building dams or mining. So what should we do? Organizations which are building such huge projects must select some other locations (if not the same) to compensate devastations done at one location. In this consumerist world we can evaluate
