Recent Flooding In India: What We Can Learn and How Can We Do Better?
The southern Indian State of Kerala has been blanketed by floods over the past few weeks and has experienced their heaviest rainfall in almost 100 years 1. While India receives monsoon rains every summer, rainfall totals in Kerala this year, have been almost 37 percent higher than last year 2.
“Having colleagues here in Maryland who have been affected by major flood events, and having worked on Hurricane Katrina, and now with friends back in India facing many of the same challenges, this hits home” says VPC President, and Disaster Planner, Deepa Srinivasan.
The Indian State of Kerala
The number of people affected from the flood events range from 220,000 3 to over 1 million people in evacuation camps since the flooding began in the beginning of August 4. Additionally, power outages, overwhelmed emergency and medical services, and the closing of the international airport have brought the region to a standstill. If all of this sounds reminiscent of a major flood event in the U.S., it is, because there are many parallels that can be drawn.
First, Kerala is an already low-lying, coastal, fishing and tourism-based region. A network of rivers and canals cut through the area, which is supported by over 80 dams. Kerala’s history of European trade and colonization draws some similarities to parts of Louisiana - low-lying U.S. coastal fishing communities with rich European history, that have experienced major flooding events. The harbor in the coastal City of Kochi, which allowed the trade industry to flourish, was carved out by a documented flood event over 600 years ago. In the State of Kerala, and in many U.S. coastal cities, the natural marshes and wetlands that once protected these coastal cities from flood events, have been drained or filled as a result of rapid development and urbanization 5. The most common concerns heard with respect to the handling of the Kerala floods include: lack of early warning; mismanagement of the dam system protecting the area; and availability of evacuation assistance; all of which were major concerns during Hurricane Katrina.

Indian Government Officials had already identified Kerala as one of the top-ten most at-risk states to flooding in the sub-continent. Despite this finding, there is limited, if any early warning programs in place across the state. The Indian Central Water Commission (CWC) is the only government agency authorized to issue a flood warning 6. Although there are flood monitoring sites in Kerala, there are no flood forecasting sites at the various dam locations or along strategic points or river junctions around the State 7.
A compounding issue is that of the dam management and release policies. It has been argued that there was adequate notice to release some of the waters behind the dams during dry periods ahead of the catastrophic flooding. Instead, officials released water from over 80 dams during the peak flood levels, which only exacerbated an already calamitous event 8. As a result, the delay in releasing the dams added to the heavy flooding from the rains already experienced in surrounding areas, causing one of the most devastating flood events India has recently experienced. It is estimated that if water from approximately 30 of those dams been gradually released prior to the peak event, that the flooding would not have been as devastating 9.
Once the dams had reached critical levels and evacuation warnings had been issued, there was still much hesitation by locals to heed the evacuation orders and leave behind their homes and property. The fear of theft, and a general mistrust of the government only further compounded the issue. These are all issues that commonly occur in many U.S. cities following severe flooding and other disaster events. An additional challenge during the Kerala floods was determining how to evacuate persons with limited mobility or how to reach residents with developmental or cognitive challenges and bring them to safety, similar to the challenges faced during Hurricane Katrina’s evacuation efforts. For those in Kerala who did not evacuate, rescue officials quickly became overwhelmed and a large-scale volunteer effort mobilized. It is estimated that over 2,800 fishermen 10 volunteered to assist with the evacuation and rescue operations.
Regardless of their location, vulnerable and affected communities face many of the same challenges when it comes to flooding and other disasters.
Flood events can be caused by weather patterns that are expected annually (cyclone season/hurricane season);
Flood events result in the most devastation in areas that do not have effective warning systems;
Flood events can be exacerbated by mismanagement of the flood control system (dam/irrigation system/levees/canals)
There is limited response to evacuation orders due to fear or mistrust; and
There is a need to bolster response and evacuation efforts by self-organized volunteer response teams.
Where do we go from here? How do we function effectively in a post-disaster situation and make the most of the available resources?
The key to the efficient and effective delivery of national resources in a post-disaster environment is preparedness. Post disaster preparedness planning is: critical to evaluate the capacity, capability, readiness of various national and state agency partners during steady-state.; and crucial to develop a Strategic Operational Plan prior to an event occurring, so it is in place when a disaster strikes.
These efforts during steady-state will result in more efficient and effective delivery of resources by helping to:
Identify staff capacity issues;
Identify and resolve potential gaps in post-disaster operations prior to an event;
Provide training for those disaster-stricken areas;
Provide easy-to-use manuals for those working on post-disaster issues; and
Identify opportunities for coordination and effective communication between national, state, local, governments and stakeholders.
Evaluate pre-disaster plans in the context of a post disaster environment
