Q. Need of planning to manage flooding: Discuss how efficient planning will helps to manage flooding in India.
Aug 03, 2016 Related to : GS paper-3

Ans :

Introduction-

Recently due to heavy rain in short span of time resulted into paralysing floods that have taken a heavy toll of life, wiped out crops and destroyed infrastructures in both rural and urban India. About five lakh people are displaced and floods have also caused massive damage to infrastructure, including roads and bridges.

Issues-

  • Paralysing floods have exposed the near total absence of planning that has marked India’s urbanisation process, and efforts to adapt to flooding of monsoon-fed rivers in rural areas.
  • Increased incidence of urban flooding that exposes the absence of planning resulting in mal-development. Excess rains are a problem in part because cities and towns are paved, hindering the natural flow of water. This problem is exacerbated by building towns without taking natural hydrology of the area into account.
  • Hence to join the ranks of developed nations, India needs to learn to manage, and not just cope with, floods. It is possible only through efficient planning system.

How planning will helps to manage floods?

  • Excessive waters due to heavy rain can be managed by proper assessment, planning and appropriate engineering.
  • Monsoon-fed rivers are prone to flooding during the rainy season, therefore planning will helps to utilise the excessive water in an efficient manner and allow the surplus to drain away without causing damage.
  • Irrigation canals can be built to capture the overflow of these excessive waters. Similarly the constructions across the drainage system hinder the flow of surplus waters, hence constructions can be allowed across the drainage system.
  • Improved river management systems can help regulate water flows, create early warning systems, to prevent damage to life and property.
  • Developments have been allowed without any regard for the carrying capacity, and without the requisite infrastructure of sewage, drainage and roads. Town planners have to be taken seriously.

Conclusion-

Every year India witnesses floods in some or the other parts of country. It has resulted into huge loss of both life and economically. The incidence of extreme rainfall events is expected to increase with climate change. As the pace of urbanisation picks up, the country needs to build cities and towns that are resilient. Rural India’s capacity to handle the extreme weather events too needs to be augmented.
