The article discusses a study on measures to adapt to flood risk in Mumbai, India. Among the recommendations by the fact-finding committee established after the 2005 floods were improving the drainage systems and installation of a Doppler radar system and automatic rain gauges as early warning systems. The authors found that these measures do not consider the effects of climate change. The study also explored the reductions in direct losses from flooding based on five scenarios.

The article examines the impact of flooding on the economy of Mumbai, India. Using the Adaptive Regional Input-Output (ARIO) model, the value added loss caused by the July 2005 flooding in 25 sectors was 395 million U.S. dollars. There was no correlation found between direct economic losses and total losses as larger disaster tend to cause larger production losses, among other reasons. The authors also predict higher indirect and direct costs from flooding in the 2080s.

The article discusses the results of a study on the impact of flooding on marginalized population and informal economy in Mumbai, India. About 90% of households were affected by the July 2005 floods while 39% of them said they had decreased food intake because of the disaster. House reconstruction costs and their comparisons with average income and savings are explored. The study also assessed the mean damage to household assets and man-day losses caused by the floods.

The article assesses the current and future flood risk in Mumbai, India. More than half of global climate models show that precipitation over Mumbai will increase. Under the A2 Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios (SRES), Providing Regional Climates for Impact Studies (PRECIS) estimates that mean temperatures will rise by 3.6°Celsius across India by the 2080s while the seasonal mean rainfall will increase by 6.5%.

The article assesses the risk of flooding and future sensitivities in Mumbai, India. First, it offers an overview of the geography of the city. The authors say that flooding every summer between 2004 and 2007 underscores the susceptibility of the city to floods, with annual rainfall of 2,400 millimeters (mm). It is said that the country experienced the worst floods in the last 100 years on July 26, 2005 when the rainfall reached 944 mm in 24 hours.

The article summarizes the findings of a study that assessed the flood risks and the benefits of adaptation options in Mumbai, India. The authors predict that an upper bound climate scenario could double the risk of flooding experienced in 2005 and losses could triple. It has found that adaptation options reduce losses associated with floods. It is stated that the impact of flooding can also be reduced by half if insurance is extended to 100% penetration.

The article presents the conclusions of a study on quantifying the flood risk and the benefits of adaptation measures in Mumbai, India. The study found that the city is at risk to heavy precipitation and has possible higher sensitivity to climate change which warrants climate change adaptation. Among the benefits of disaster risk management and adaptation measures such as drainage system upgrade are reduction in losses and indirect losses.

The article discusses a study on quantifying the flood risk and the benefits of adaptation in Mumbai, India. Among the uncertainties integrated into the analysis were hazard, exposure and vulnerability. The authors believe that the study can help in risk-reduction decision-making due to lack of information on the cost of risk-reducing efforts available. They add that more studies are needed to determine the effects of floods on food for various social groups.

An introduction to a study that assessed the flood risks and benefits of various adaptation measures in Mumbai, India is presented.
