Context:

  • As per data from the Disaster Management Division, Ministry of Home Affairs, in the recent few months heavy rainfall has caused devastating floods in several States, resulting in more than 1400 lives being lost, and more than 3.5 lakh houses being damaged, and crop damage in over 300 districts.

Background:

  • In India, out of the total geographical area of 329 million hectares (mha), more than 40 mha is flood prone.
  • Increased frequency of floods in traditionally less flood-prone areas is a cause of concern and poses challenges before the policy makers.
  • According to the Global Climate Risk Index 2021, India was the seventh worst hit country in 2019 due to extreme weather-related events.
  • States across the nation have reported casualties due to floods and Himachal Pradesh ,Assam and MP being the top 3 states with maximum casualties.

What is Flood?

  • Usually a flood is an overflow of water that submerges land that is normally dry. It is one of the most common severe weather events. There are broadly three common type of floods:
    • Coastal Floods: inundation of dry land areas along the coast with seawater .It is caused by storm surges associated with tropical cyclones and tsunami.
    • Flash Floods: led by sudden ,rapid and extensive rainfalls.
    • River Floods: Caused when continuous rain or snow melting over the period forces a river to exceed its capacity.

Causes of Floods in India:

  • One major cause is India’s rapidly altering geo-climatic and socio-economic conditions .
  • Growing developmental and economic activities in flood plains
  • Vast network of rivers in which the rivers bring heavy sediment load from catchments. These, coupled with inadequate carrying capacity of rivers are responsible for causing floods, drainage congestion and erosion of river-banks.
  • Cyclones, cyclonic circulations and cloud bursts cause flash floods and their frequency has increased due to varying climatic conditions.
  • Rapid urbanization has significantly altered the geographical landscapes, especially in coastal areas making them vulnerable to floods.
  • Deforestation has led to reduced resilience of land against natural catastrophes such as floods and tsunamis.
  • Higher population growth is causing an unprecedented burden on natural resources and they are being rapidly exploited which has disturbed the natural cycles and harmony.
  • Irregular rainfall coupled with global warming and climatic phenomena such as El-Nino.

Floods in India : Data and Statistics

  • Floods are the most recurrent phenomena in India after cyclones and are amongst India’s most lethal and costly disasters.
  • In 1980, Rashtriya Barh Ayog (RBA) estimated 40 million hectares (mha) of land as flood-prone, which has increased by around 14 per cent to 45.64 mha in 2011.
  • A 2022 report from the Central Water Commission states that death from floods increased from 37 in 1953 to 1,815 in 2020.
  • The loss due to floods increased sharply, from about ₹50 crore in 1950s to about ₹21000 crore in 2020.
  • Overall, over 1 lakh people have been killed, and over 2000 million people have been affected due to floods since independence.
  • The floods have caused economic losses of about ₹4.4 lakh crore, while losses on account of damage to crops and public infrastructure stood at about ₹1.3 lakh crore and ₹2.3 lakh crore, respectively.
  • On average, the Indian economy’s annual loss due to floods was about ₹6500 crore.
  • According to a paper Parida et al (2020) India lost around 0.46 percent of GDP yearly due to floods. Damage to crops has been estimated to account for around 0.18 percent of GDP.

Flood Management In India : The major flood management and control agencies in India include:

  • National Disaster Management Authority (NDMA): The job of relief and rescue is carried out by the National Disaster Response Force (NDRF) with state counterparts.NDMA works under Prime Minister’s Office (PMO) – and National Institute of Disaster Management (NIDM) – works under the Union Ministry of Home Affairs (MHA).
  • India Meteorological Department (IMD) – provides rainfall or cyclonic event forecasts which are used by all the agencies for preparedness to deal with floods.
  • Central Water Commission (CWC) – The main job of CWC is to procure the data of hydrology at the national level – like river discharge measurement and water level in dams etc. to alert the states about any imminent or potential flood.

National Disaster Response Force(NDRF):

  • Origin
    • The Disaster Management Act 2005 which established NDMA has a statutory provisions for constitution of National Disaster Response Force (NDRF) for the purpose of specialized response to natural and man-made disasters.
    • Accordingly, in 2006 NDRF was constituted with 8 Battalions
  • Present Organization:
    • At Present, NDRF consists of 15 battalions from the BSF, CISF, CRPF, ITBP, SSB and Assam Rifles.
    • Each battalion has 18 self-contained specialist search and rescue teams of 45 personnel each including engineers, technicians, electricians, dog squads and medical/paramedics.
    • The total strength of each battalion is 1,149.
    • Battalions are trained and equipped for response during natural and man made disaster including chemical, biological, radiological and nuclear (CBRN) emergencies
  • Functions:
    • To minimize damage, caused due to natural and man made calamities in the country.
    • “Proactive availability” to the States and that of “pre-positioning”, in threatening disaster situations..

Impact of floods

  • The increase in flood-prone area has caused infrastructure damage and claimed numerous lives which have been aggravated by rapid climate change.
  • Another adverse impact of floods is the disproportional rise in the fiscal burden of the Central and State governments, through spending on disaster management activities.
  • Floods destroy standing crops posing a challenge to Food security and Inflation in the country.
  • Urban flooding has become a common threat to city dwellers due to poor town planning and a dearth of investments in infrastructure.
  • Adverse impact on the employment opportunities in rural areas, thus hastening inequalities, poverty and loss of livelihoods.

Way Forward : measures to mitigate floods

  • Creating A National Disaster Database which will help policymakers and academics devise long-term flood management policies.
  • As the problem of urban flooding is becoming more severe, and losses are increasing each year, the issue merits concerted attention from policymakers with appropriate implementation of the NDMA guidelines on Urban Flooding 2010.
  • Strict implementation of the Coastal Regulation Zone (CRZ) notification issued in 1991 (revised in 2011 and 2019 )with the primary intention to address coastal zone management issues
  • Use of Intelligent flood warning systems like IFLOWS (integrated flood warning system)
  • National Flood Commission recommendations have failed to achieve much success in mitigating floods which need to be remodeled.
  • To mitigate the impact of floods, better disaster management policies are needed such as:
    • Greater spending on building flood-resilient infrastructure
    • Improving and enhancing capacity of flood warning systems
    • Construction of flood shelters in coastal districts
    • Improving river connectivity and construction of river embankments,
    • Creating and implementing community awareness programmes.
    • Providing pucca houses to poor households in low-lying areas.
