Human perceptions of personal and community level risks vary greatly, and strongly influence aggregate vulnerability. Houses should be constructed such that they can withstand the heavy rainfall and forceful winds. Cyclone and storm surge data for the 19th and 20th centuries for the Bay of Bengalcoast of the state of Orissa in India are available … In the case of tropical cyclones, potential landfalling regions now have more infrastructure at risk than in previous decades. Studies indicate that natural disaster losses equate to up to 2% of India’s Gross Domestic Product (GDP) … There are many steps that people can take that will leave them prepared for when a cyclone hits. cyclone shelter, warning system) used to reduce the impacts of tropical cyclone hazards (Coppola, 2006; Khan, 2008). His interest in tropical cyclones began with his involvement in the investigation of damage to Townsville by Cyclone Althea in December 1971. homeowner insurance rate reductions), and homeowners willing to invest in reducing their likelihood of property damage. Cyclonic Hazards in Odisha And its Mitigation Saptaparna Mishra Dipika Kar like cyclone. The Eastern India Super Cyclone occurred on Oct. 29, 1999 and caused deaths of about 9000 persons. These normally occur during different months of a year like April-May or September – November. Cyclones enforce people to evacuate their habitats. High population density, better employment opportunities and economic compulsions encourage people to occupy areas which are susceptible to cyclones, saline ingress and flooding. Keywords: Cyclone mitigation encompasses the actions and planning taken before a tropical cyclonestrikes to mitigate damage and injury from the storm. The continuing population growth in natural hazard prone regions is accompanied by an increase in actual and potential hazard related economic losses. Create an early warning system that can quickly disseminate … Steps in Being Prepared. 59% of the landmass is prone to Earthquakes • Approx.12% (About 40 million hectares of land)is prone to flood and river erosion. The tidal surges cumulatively give birth to a cyclone. Introduction: India is highly vulnerable to natural hazards especially earthquakes, floods, drought, cyclones and landslides. Traditional homes should be improved by building in. Government is carrying out a National Cyclone Risk Mitigation Project (NCRMP) with the help of the World Bank for upgrade cyclone forecasting, tracking and warning systems in India Government is also implementing Integrated Coastal Zone Management Project (ICZMP) to improve national capacity for the implementation of comprehensive coastal management in India. These mainly affect the coastal areas located along the Bay of Bengal and Arabian Sea. In fact, these are atmospheric disasters that occur mainly in coastal areas like coastal regions of Bangla Desh and India. Recognizing this, the Government of India has considered the hazard risk mitigation approach through short term and long term measures, which lay greater emphasis on prevention, preparedness and mitigation. Cyclones damage coral reefs and mangroves that are habitats of large varieties of animals. Cyclones occur in a certain atmospheric area from where they spread in different directions. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review. Storm surges generated by the strong tangential wind stressesand normal atmospheric pressure gradients at the sea surface due to tropical cyclones (TC'S)have been studied with the goal of detecting any significant and systematic changes due to climatechange. Attribution of tropical cyclones to climate change is difficult. Thanks to the careful efforts of the meteorological department and the attention of the media that people get time to save themselves and their property up to the possible extent. Mitigation capacity involves structural and non-structural initiatives (e.g. Plantation of green belts along with coastal line in a scientific interweaving pattern can reduce the hazard due to a cyclone. Cyclones are extremely disastrous hazards that originate in seawater. risk modeling, hazard loss, tropical cyclone. iv. Mitigation of the effects of tropical cyclones on human settlements - An Australian perspective George R. Walker The author is Associate Professor in Civil Engineering at James Cook University of North Queensland, Townsville, Australia. What actually makes these hazards turn into disasters is the vulnerability of the people, their means of livelihood and the fragility of infrastructure. Awareness, education, preparedness, and prediction and warning systems can reduce the disruptive impacts of a natural disaster on communities. • High water levels in the rivers as a result of the heavy rainfall associated with the cyclone. It maps the pattern of old cyclones using … Mitigating factors: Though the weather system crossed the coast as a very severe cyclonic storm and brought heavy to extremely heavy showers, the … Learn how your comment data is processed. on Cyclones and – Ways Of Their Mitigation. It is anticipated that the findings of this work will be used to inform a broader effort to create a more cyclone resilience NQ. Some important measures for mitigation of cyclones are mentioned below-. The broad rotation of a landfalling trop… The Eco-Trends Copyright 2020. These are usually followed by rains and wind of very high speed. 1. Orissa, Andhra Pradesh, West Bengal, Gujarat, Kerala, Karnataka and Maharashtra are states of India worst affected by Tropical Cyclones. With their unique mixes of varied contributions from Original Research to Review Articles, Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Required fields are marked *. Thus, a depression or the area of low air pressure is created which is called as the centre or the eye of the storm. Cyclone Katrina occurred from Aug. 23–30, 2005, in New Orleans, Louisiana, Southern USA, and caused deaths up to 1000. Add your answer and earn points. Existing residential buildings (commonly the largest contributor to insured losses) may be hardened against wind loads and wind driven rain ingress by improving building envelope components and systems wind resistance and improved top-down load paths. These usually extend vertically up to 12 to 14 km and horizontally up to 150 to 1000 km. Policies should be made to regulate land use and enforcement of building codes. While vulnerability, exposure, and hazard act simultaneously to contribute the risk of natural hazard, but mitigation capacity reduces the risk. The recent advances in mitigation methods and multi-disciplinary risk modeling may be further enhanced by the study of human behaviors in preparation for and response to tropical cyclone events. | Designed By, Contribution of BAU- Ranchi in Oilseed Production, Home Stay – A Project to be launched in Bihar, Forest Rights Act and the Depletion of Forests, Dahlia – One of The Amazing Flowers of winter, Eat Kathal to Boost Up Your Body Immunity, Selling Mahaviree Flags in Corona offschool, Sarhul- The Festival that Links Life to Nature. Mitigation of damage. Your email address will not be published. Damage mitigation research and implementation plays an important role reducing the vulnerability of infrastructure. Cyclones have various types of serious impacts on life, property and environment. This trend of continued hazard prone development is unlikely to abate, and has driven multiple related fields of hazard research to mitigate damage and better quantify economic risk. Plantation of green belts along with coastal line in a scientific interweaving pattern can reduce the hazard due to a cyclone. National Cyclone Risk Mitigation Project (NCRMP): Context: Launched by the Centre to address cyclone risks in the country. Meteorological records of wind speed and directions should be kept properly so as to predict for future cyclones and to make advanced preparations. It is an intenselow-pressure centre associated with theconvergence of wind rotating inwards to the low-pressure point forming a closed cyclonic vortex. The objective of the Project is to undertake suitable structural and non-structural measures to mitigate the effects of cyclones in the coastal states and UTs of India. These models are commonly used by the insurance industry (and insurance regulating government entities) to determine risk-consistent rates and to conduct cost-benefit analyses of mitigation measures. Tropical Cyclones: From Science to Mitigation. Local storms are called tornados. Examples of some devastating Super Cyclones are –. particularly extra-tropical cyclones, to inform short-term mitigation strategies against the impacts of hazardous weather such as high winds and heavy rain. cyclone mitigation status relative to others in the community may promote mitigation action. The storm surge, or the increase in sea level due to the cyclone, is typically the worst effect from landfalling tropical cyclones, historically resulting in 90% of tropical cyclone deaths. Inadequacy of infrastructure adds to the vulnerability of public and properties. The National Cyclone Risk Mitigation Project (NCRMP), to be implemented with financial assistance from the World Bank, is envisaged to have four major components: Component A: Improvement of early warning dissemination system by strengthening the Last Mile Connectivity (LMC) of cyclone warnings and advisories. A lot of oil is spilled on the surface of sea-water which damages ocean-ecosystems. National Cyclone Risk Mitigation Project Indian coasts are highly vulnerable to tropical cyclones and consequent recurrent loss of life and property. This site uses Akismet to reduce spam. When this condition of very low atmospheric pressure is combined with forces of strong speedy wind (with a speed ranging from150 to 400 km per hour) on sea surface, it causes unusual rise of sea-waves called as Tidal Surges. Management and Mitigation of Cyclones and Hurricanes: ADVERTISEMENTS: i. Coastal areas should be well prepared to meet eventualities that arise from cyclones. Your email address will not be published. Engineering advances are a necessary but insufficient aspect of hazard risk quantification and vulnerability reduction. They also help in checking the soil erosion and inward sand drift, thereby protecting cultivated fields, houses and homesteads near the coast shows coastal shelter belt. They are large revolving vertices in the atmosphere extending horizontally from 150-1000kms and vertically from the surface from 12-14kms. The mitigation measures as proposed by the UN-HABITAT are given below: Hazard Mapping – It suggests that using hazard mapping, one can predict the vulnerable areas affected by the storms. Cyclone Mitigation. Buildings in coastal areas should have high engineering inputs. It is expected that this will be used for the school teachers, students, parents, NGOs, ... people during Cyclone Bhola in 1970. Cyclones and mitigation measures Tropical cyclones are the worst natural hazards in the tropics. In the case of tropical cyclones, potential landfalling regions now have more infrastructure at risk than in previous decades. However, a robust increase of the most devastating storms with climate change is evident. Component B: Cyclone risk mitigation investments. Damage to the coastal Odisha due to cyclonic disaster hits state economy very hard. Cyclone and Coastal Environment The coastal land of Bangladesh (710 km long) is of recent origin formed out of the process of sedimentation. iii. article downloads Cyclones are natural events that can neither be caused nor prevented. Most parts of the area are, therefore, low lying which can be subject to inundation even under ordinary circumstances of tides. reroofing permits requiring modern building code compliance), incentives (e.g. During the 19th century,there were 72 flooding events associated with cyclones, whereas in the 20th century therewere only 56 events. Accurate weather forecast and satellite imaging to see developing cyclones in advance. • An increase in water level (or storm surge) in the Bay of Bengal produced by low pressure and the strong wind field of the cyclone. M itigation — actions taken to prevent or reduce the risk to life, property, social and economic activities, and natural resources from natural hazards — is central to the Decade initiative. Mitigation Measures. Disasters due to cyclones can be prevented by adopting safety measures and by constructing barriers. Coastal districts of Orissa. National Cyclone Risk Mitigation Project. Cyclone disaster mitigation is a major concern in Bangladesh. Traditional mechanisms of disaster management have been the mainstay for these people to counter hazards by remaining united. Cyclone disaster mitigation arrangements were organised in the maritime states of India only during the last 25 years. Everyone should develop a family plan, create a disaster kit, have a place to go, and secure your home. Translating physical damage and recovery efforts to local and aggregate economic loss is highly nonlinear and requires economic (finance, actuarial) modeling expertise. • High tides in the Bay of Bengal. Wide buffer zones of forests should be managed properly along the coastal line so that cyclone may not run freely to penetrate inland. Shelter beds should be created to check soil erosion and speed of winds. So proper planning, mitigation strategy andpreparedness is badly needed to reduce the disastrous consequences of cyclone. 1. Mitigation means actions taken to prevent or eliminate the natural disasters or hazards like flooding, earthquake, landslides, wildfires or dam failure to happen. MITIGATION OF FLOODING AND CYCLONE HAZARD IN ORISSA, INDIA 457 Figure 2.
