IHE Delft flood resilience experts try to answer this question. The beauty of Kerala, its undulating terrain and number of rivers, seem to have shown its dark side, leading to the loss of more than people, displacing , people, not to mention the damage to private property and public infrastructure. The economic damage due to flooding is yet to be ascertained. In spite of disruptions to rail, road and air traffic movement, the people of Kerala, neighbouring states, the local government department and the central government agencies came together and coordinated relief measures, which have prevented the events snowballing into a major public health catastrophe.
Flood risk is a combination of the likelihood of the occurrence of flooding and the impact due to flooding.
The occurrence of swelling rivers and overflowing banks can be due to the combined effect of rains and haphazard reservoir management. However, the increase in impact in majority of cases seems due to human factors.
The flooding in rivers is attributed to the excessive monsoon rainfall, as well as the excessive flow from the majority of the 56 big dams that were open during the extreme rainfall. Each of these dams has a storage capacity of more than 60 million cubic metres. Although it is difficult to pinpoint the cause of flooding to excessive rainfall or the opening of these dams, what is baffling is i the level of water beyond these dams, almost at the crest level in the first week of August; ii the release of water during the time of extreme rainfall; iii lack of knowledge among the nodal agencies and public about those areas most likely to be flooded; iv encroachment of flood plains; v lack of awareness about evacuation routes and safe areas.
Also Kerala is one of the most urbanised states in India. However, urbanisation is uncontrolled: basic urban planning rules are often disregard due to the narrow focus on short term economic gain and real estate development. This is evident from the flooding of upmarket built up areas such as gated communities that have sprung up in the flood plains of Periyar.
Why these reservoirs were not emptied in anticipation of rains in the upcoming two weeks; were these forecast windows not sufficient to empty the reservoirs; were these forecasts not reliable; when rainfall events can be forecast, why were the impacts not forecast and anticipatory actions rolled out; why were standard operating procedures not in place to trigger anticipatory actions?
Disruption in availability of clean water, transportation, and communication can affect human health.
Even though flooding cannot be avoided, the impact of floods can be mitigated. These impacts are aggravated by loss of health workers and damage to health infrastructure.
In the medium term, complications of injuries, infections, psychiatric morbidities, communicable diseases, and starvation result. Long-term health effects of floods are chronic diseases, psychiatric comorbidities, poverty, and malnutrition.
Hepatitis A and E can spread by feco-oral route. Leptospirosis can be transmitted by direct contact with contaminated water.
Overcrowding can spread respiratory infections due to displacement. Tetanus is not transmitted person-to-person, but contaminated wounds can cause the illness in areas where vaccination coverage is low.
The effects of floods will be different in high-income countries as compared to low-income countries. Inadequate supply of drugs due to disruption of transportation resulted due to the floods.
This hampered the distribution of drugs for communicable and noncommunicable diseases. The emotional and psychological consequences were high due to loss of belongings, houses, and family members. In our study, we aimed to assess the morbidity profile of patients attending the medical camps conducted at Chennai during the postflood period.
Methodology Study area Medical camps were conducted in two revenue blocks in Thiruvallur district, namely, Minjur and Pulal. Thiruvallur district is one of the worst affected districts during the South Indian floods along with Kancheepuram and Chennai.
Minjur is a periurban area with an average elevation of 11 m above the sea level. It is situated around 25 km from Chennai city.
An extreme high-intensity rainfall occurred over these regions from November 27, , to December 4, , causing floods. Incessant rains, global warming, rapid urbanization, and poor drainage system in these areas observed to have contributed to flooding. Data were obtained on the age, sex, and presenting complaints from the camp attendees. SPSS Inc. Released Duration The camps were organized from December 13, , to December 17, Results Total number of patients seen in camps was Total number of health problems identified among people who came to the camp was A total of males and females attended the camp.
Of all the presenting health problems of those who attended the camps, Table 1: Age- and gender-wise distribution of morbidities Click here to view Most of the persons who attended the medical camp belonged to the female sex This could be attributed to the fact that the camp was conducted during the working hours of the male population and most females were homemakers.
Adults aged 19—59 years formed the most common age group attending the medical relief camps.
