1. RESEARCH POSTER PRESENTATION DESIGN © 2011 www.PosterPresentations.com Disaster management Strategies in River basin Management - A case study of Indo Gangetic Basin §Should there be rivers in the land which drain off from the ground the stagnant water and the rain water, then the people will be healthy and bright. But if there be no rivers and the water that people drink be marshy, stagnant and fenny, the physique of the people must show protruding bellies and enlarged spleen.- Hippocrates §In India, the Indo-Gangetic basin extends from Punjab to Assam and the total basin area is 225.2 million ha & the net cropped area is 114 million ha. § The most intensively farmed zone in the country, wheat being the major crop in the western part and rice is grown in the eastern section. §Rapid change in land use, cropping and water use patterns, partly as responses to changing demographics and consumption patterns, and partly as responses to changing investment scenarios and economic growth. §Some of the largest cities are expanding to low lying areas which are preserved as wet lands and drainage channels acting as buffering zone for floods. §The river banks and drainage areas have some of the biggest and most polluting factories and plants which result in degradation of water quality as a lot of waste is dumped into the water and it affects population living downstream. §The most effective disaster management mitigation can come about by a multi-pronged river basin management strategy. § Major Problems- Flood, Drainage congestion, Erosion, Water quality degradation, Uneven distribution of rainfall. Introduction Objectives § Micro-irrigation-As means to save water in irrigated agriculture. § Water-Shed Management (Micro and Macro level)-It is important for the improvement and maintenance of good water quality. In the recent years the water quality standards have come under stress due to increasing population, depleting water resources, bad management practices. § Embankments- Provide a reasonable amount of protection against small and medium sized floods. Shifting of river courses checked. § Afforestation- 1) Minimize soil erosion 2) Decrease Soil sediments §Flood Plain Regulation- Regulation of land use in flood plains thus decreasing the chances of disaster. § Flood Proofing- 1) Raising of villages 2) Quick drainage facilities § Disaster preparedness and management- Pre, Present and Post §GAP for effective Water quality management. § Flood Insurance- yet to be implemented Methods §The Government of India launched the Integrated water-shed Management plan in 1980-81 for the Indo Gangetic Basin. §Lack of coordination among federal and provincial governments, research institutes, and national and international organizations; conventional farming and irrigation methods used by farmers; limited attention to reclamation and saline agricultural approaches; and lack of resources are identi?ed as some of the reasons for the low success rate. §Results of studies funded under GAP- Ø75 per cent of the pollution load was from untreated municipal sewage Ø88 per cent of the municipal sewage was from the 25 Class I towns on the main river. ØOnly a few of these cities had sewage treatment facilities (these were very inadequate and were often not functional) ØAll the industries accounted for only 25 per cent of the total pollution (in some areas, such as Calcutta and Kanpur, the industrial waste was very toxic and hard to treat). §Multiple uses of water are gaining importance in the IGB. It has been undertaken at experimental farms, watersheds and farmers field. Integrated Rice-fish system §In Indo Gangetic plains (IGP) simple seed priming technique soaking chickpea seeds in water and micronutrient solution for six hours and drying in shade could establish good chickpea crop in rice fallow areas and increase crop production and incomes by using residual soil moisture. This technology can be applied in 12 m ha rice fallows in India spread in MP, Orissa, Jharkhand, West Bengal and Chhattisgarh. §Bank erosion by the Ganges& its tributaries has become a matter of serious concern and erosion control works are very expensive. § Several capital towns situated on riverbanks have been provided protection against 100-years’ floods and are fully protected by embankments. § Adverse effects of Embankments:-Induced drainage congestion and water-logging behind the embankments and Enhanced flood problems in unprotected area between the embankments. § Under GAP A total of 261 sub-projects were sought for implementation in 25 Class I (population above 100,000) river front towns. § Importance was given to generating awareness through intensive publicity campaigns using the press and electronic media, audio visual approaches, leaflets and hoardings, as well as organising public programmes for spreading the message(for GAP). § To regulate flood-plain use, the land has been divided into three categories: Prohibitive river channel and floodway of design flood (100-years’ flood); Restrictive extent to which inundation is caused by design flood (50-years’ flood); and Warning extent to which the largest flood spreads (25-years’ flood). § Villages mainly raised in Uttar Pradesh, West Bengal and Haryana in the Gangetic basin. § Flood forecasting was brought into operation in 1969 by the Central Water Commission (CWC). Results Conclusion § Focus is on river basin management through disaster management methods. §Construction of dams though mitigate flood problem and facilitates irrigation is time consuming, expensive, involves community relocation, approval from neighboring countries and hampers aquatic and terrestrial bio-diversity. § Community participation is essential for proper implementation of large scale micro-irrigation, water shed management and in emergency scenarios. § Better administrative procedures and monitoring of flood protection works before flood season. §Mass Media should be active and efficient wire less network should be available during emergency .
