How could the economic impact of climate change on human health in India be modelled using epidemiological methods, such as those used to model the transmission of vector borne diseases?
Due to climate change ,atmospheric temperatures have increased which have effect on the productivity plants,drying up of water systems,increase in population some disease transmitting vectors and a general decrease in human productivity per hour/increase and general burden on both the private sector and governments.
I am examining an impact of climate change on allergic disease including asthma, allergies (eyes, nose and sinuses). with funding from the EPA over the next several years.
It all depends on the data available to you. A blunt approach would be to map mortality and atmospheric data against average life expetancy (both in time and in space) and calculate years of productive life lost. This is possibly the coarsest method, but these data are usually easily available, with better more granular and specific data you can do much better.
Well, I did an analysis of the impacts of public health (prevention and promotion) measures on preventable chronic diseases and presented a paper in the International Health Outcome COnference, held in Canberra, Australia.
From the methodological perspectives, some hints here:
1. List all diseases that would end up with increased/decreased mortality and morbidity due to climate change. You can use the published evidence as the basis.
2. Again using published papers, arrive at the percentage of population likely to be affected by increased or dcreased morbitdity or mortality.
3. Now estimate the impacts on qulaity of life and life yrs saved (QALY, DALY).
4. ALso estimate the increased health care costs due the likely changes in morbidity and economic impacts of mortality as well as morbidity.
In case you want to measure the CBA or CEA of increased investment to prevent the climate change (limited impact by national action vs global action), compare the cost with increased benefit in the form of savings in health care costs, productivity saved etc.
Good luck with your reasearch Saravanan
Dr Kannan
I agree with Arbeen, Please collect exhaustive information on economic al and climate related and follow them for particlar disease. or doseases. You can review lietarue regarding all these variables as mentioned with Kannan.
Good luck

Communicable, infectioue and vector borne disease are connected with environment.
It has been well documented tha tmalaria in the pujab in 19th and 20th century had a 7 year cycle in consonent eith teperature and rainfall. the weather is changing so is the ecology of the diseases.. Ecological epidemiology is required to elucidate the changinf relation of disease pattern.
It would be best to state that perception of vulnerability and its impact on health is highly subjective on how the general population views climate change. Since in many countries there is a trade off between spending on climate change adaption in relation to the health sector expenditure ver sus ensuring fiscal activity.
