Estimating the uninsured losses due to extreme weather events and implications for informal sector vulnerability: a case study of Mumbai, India

Abstract

Extreme weather events lead to significant physical, economic and social impacts with short- and long-term consequences for affected regions. The methodologies used to assess the impacts often focus on the insured losses associated with private capital and public infrastructure. However, these estimates do not reflect the losses, monetary and non-monetary, associated with damage to uninsured assets. In addition, in the absence of systematic methods for measuring and recording impacts experienced by the informal sector—both households and small businesses—losses experienced by these segments are not reported, particularly in the developing world. This paper uses primary data collected from a survey of households and small businesses to estimate the uninsured losses due to a major flood event in the city of Mumbai, India. A detailed characterization of the losses is attempted, by disaggregating losses into monetary damage to property, physical capital, assets, equipment and inventory as well as loss of income, investment and disruption of essential services. Aggregate estimates of losses at the city level are computed and compared with the insured private and public losses traditionally reported in the literature. Our results indicate that the uninsured private losses suffered by individuals and small businesses significantly exceed the damage to public infrastructure. In the absence of insurance or government assistance, these costs represent a significant out-of-pocket expenses for the households and businesses. These findings have significant policy implications in terms of highlighting the vulnerability of the informal sector to extreme weather events in cities of the developing world.

Notes

  1. 1.

    Insurance density and penetration are the two indicators of the extent of insurance coverage in any country. Insurance density is the total premium income per person in a country’s population (UNCTAD 2007), and insurance penetration is the ratio of premium underwritten a given year to the Gross Domestic Product (GDP) (IRDA 2013).

    Kutcha structure has walls and roof made of materials such as unburnt bricks, bamboo, mud and grass. A pucca structure has walls and roof made of concrete, cement, bricks, stone blocks, metal sheets, corrugated iron, poly vinyl chloride (PVC) material and so on. Semi-pucca structures are a combination of the two structures, kutcha and pucca (NSS 2010).

  3. 3.

    Chawls are long (and mostly single-storey) buildings divided into many separate and often single-room rental tenements offering cheap and basic accommodation. Such buildings were constructed in Mumbai decades ago to provide housing to textile mill workers and other labourers who migrated into the city. Many of these buildings are in poor and dilapidated conditions now.
