Economic impacts of climate change on Mumbai, India
Key points include:
- frequent floods and salt-water intrusion will affect the structural stability of high-rise buildings
- sea-level rise will result in a loss of coastal area and ingress of sea water, which will lead to monetary loss due to buildings being affected in the region close to the shore
- human health is another major area where the impact of climate change could be very severe, resulting in the increase of three major illnesses: diarrhoea, malaria, and leptospirosis. Iincrease in the incidence of malaria, diarrhoea and leptospirosis will result in loss of income due to non-working days and deaths
- estimated costs due to climate change in Mumbai include: dislocation due to extreme events of flooding; material damage to low-lying areas; mortality costs due to extreme events of flooding; building-foundation damages; and loss of tourism.
- micro-level planning for development of effective drainage system is needed
- greater investment in health sector will be needed for treating people affected by climate change
- anti-erosion measures will need to be put in place at beaches and seafronts
- the protection plan for mangroves and other wetland areas needs to be implemented
- energy conservation measures at all levels (appliances, building design, energy use pattern and alternative sources of energy, etc.) need to be instituted
- an urban ecosystem enhancement (creation of more open spaces, greenery, parks and tree-lined roads, etc.) needs to be undertaken.
