The hindu

Why this question

The Lancet countdown on health and climate report was released recently. Coming on the eve of the UN climate conference in Katowice, Poland, the report of the Lancet panel for 2018 brings clarity, placing connected issues in perspective for governmental action. At a time, when climate change is having multifaceted impacts, understanding the health impact of climate change as explained in the report is important.

Key demand of the question

The question expects us to first highlight that heat waves have become quite frequent as a result of climate change. Thereafter, we need to examine the adverse socio economic and health impact of heat waves and analyze how India should deal with the problem.

Directive word

Examine – When you are asked to examine, you have to probe deeper into the topic,  get into details, and find out the causes or implications if any .

Structure of the answer

Introduction – Explain that one of the major fallouts of climate change is persistent heat waves.


  • Explain the adverse health impact of heat waves
    • There has been increase in frequency, duration and intensity of heat waves in India which has resulted in increased deaths due to heat stroke, heart failure, acute kidney failure and frequent cases of dehydration.
    • Because of heat waves, there has been loss of work hours and labour capacity. The maximum impact of heat wave has been in the agricultural sector – a large section of the population that depends on farming.
    • This has resulted in decline in household income. As per World Bank estimate, in India there will be high socio-economic cost which may lead to erosion of 2.8% of GDP by 2050.
    • The increase in heat wave may also result in pre-mature deaths, increase in vector borne disease, decrease in labour capacity and it will also adversely affect food production leading to food insecurity.
  • Highlight what should be India’s response
    • Identification of heat spots
    • Review occupational health standard
    • regulate safety of work force amid rising temperature. Etc

Conclusion – emphasize on the seriousness of the problem and discuss way forward.
