MAJOR IMPACTS

                                                  MAJOR IMPACTS

Impacts Flood is a natural disaster and as we know natural disasters have many bad impacts on lives rather than good impacts. But due to our educational purposes, we will try to deeply cover both in Assam’s perspective.
Bad Impacts: –

1.  Flood creates huge destructions in life and property. No matter is it a human, animal or just any other non-living object; it destroys everything. A report shown in 2012, Assam alone loses more than 500 crore rupees each year due to this problem. In 2016 nearly 2 million people affected and 28 people died from it.

2.  Flood’s 2 bad impact is landslide or soil erosion. Heavy flooding creates high soil erosion in districts like Majuli, Sivasagar, Jorhat, Dhemaji, and Lakhimpur. As we have learned on the above that once Majuli was the largest river island in the world but due to high soil erosion it lost its old prestigious identity. 

3.  Assam is a backward state, though it is still trying hard to grow itself; but these natural disasters not letting it grow itself more. Each year this north-eastern state needs to do more hard-work to recover its economy again and again, which it loses due to flood. It affected badly on the economic condition of this state. 

4.  Flood has two different scenes; one is during the flood and another is after the flood. When flood affects an area the people living there faces a lot of problems, 

Good Impact: –

It makes the land of Brahmaputra valley more fertile, which helps the cultivators to gain more agricultural crops. Therefore this state is highly productive in rice, sugarcane, mustard, and many more crops.

Floods contribute to the health of ecologically important wetland areas. Healthy wetlands promote healthy water supplies and even affect air quality. Floods inundate wetlands with fresh waste. They also carry and deposit nutrient-rich sediments that support both plant and animal life in wetlands. In addition, flooding adds nutrients to lakes and streams that help support healthy fisheries.

Returning Nutrients to Soil

Floods distribute and deposit river sediments over large areas of land. These river sediments replenish nutrients in topsoil and make agricultural lands more fertile. The populations of many ancient civilizations concentrated along the floodplains of rivers such as the Nile, the Tigris and the Yellow because periodic flooding resulted in fertile, productive farmland. The construction of the Aswan High Dam in Egypt prevented the Nile from flooding major population centers downriver, but it also depleted once fertile agricultural lands along the banks of the river.

Recharge and Replenish Ground Water

Many population centers depend upon ground water and underground aquifers for fresh water. Flood waters absorb into the ground and percolate down through the rock to recharge these underground aquifers, which supply natural springs, wells, rivers and lakes with fresh water.
