Sand Mining

For thousands of years, sand has been used in construction. Today, demand for sand continues to increase. But excessive exploitation can have disastrous results. This calls for responsible policies from authorities and discipline fromMining operators.

Excessive sand mining causes degradation of rivers, lowers the stream bottom, which will lead to bank erosion. saline-water intrusion from the nearby sea. The effect of mining is compounded by the effect of sea level rising.

It is also a threat to bridges, river banks and nearby structures. Sand mining also affects the adjoining groundwater system and the uses that local people make of the river. It also results in disastrous consequences to eco systems like flora, fauna and water creatures.

Sand mining generates extra vehicle traffic, which negatively impairs the environment. Where access roads cross riparian areas, the local environment may be affected.

Andhra Pradesh is said to be in grip of illegal sand mining. This is over and above the permits issued by authorities at degradation levels. Such illegal mining spawn crimes like corruption, use of muscle power, amassing ill gotten wealth.

Nature has a way of taking revenge, only it is patient. When it strikes, it will be a mortal blow.
