South Asia is more vulnerable to Geo disasters and impacts of climate changes in recent years. On 26 December 2004 massive waves triggered by an earthquake surged into coastal communities in Asia and East Africa with devastating force. Hitting Indonesia, Sri Lanka, Thailand and India hardest, the deadly waves swept more than 200 000 people to their deaths. Also in an another extreme climate change phenomenon during last week of July 2005 , causing heavy rains and flooding situation in the Mumbai ,and state of Maharashtra.
More than 20 million population in the Mumbai metro region alone and 50 million all over the state are witnessing the social- economical and ecological risks and impacts due to climate changes . The economic losses to coastal ecosystem, agriculture, irrigation, aquaculture, drinking water resources, coastal industries and infrastructure are very high due to extreme geo-disasters that are linked with environmental and climate changes .The ecosystem, economic system, agriculture and aquaculture system in this region are severely affected and need systematic rehabilitation. Also mitigating the geo-disasters, marine hazards and rehabilitation during post tsunami period , scientific knowledge is needed, requiring experienced research communities who can train the local population during tsunami rehabilitation.
ISDR,AVCCE, India and CGSI jointly started the initiatives on the problem identifications in management of risks in geo-disasters, tsunami rehabilitation etc., to investigate problems related to social-economic and ecological risks and management issues resulting from the December tsunami and Geo- disaster, to aid mitigation planning in affected areas and to educate scientists and local populations to form a basis for sustainable solutions. This presentation reviews the status and issues of Geo-risks, marine risks along Indian coast focusing on technical issues, problems and damage arising from the extreme floods, tsunami in agriculture, aquaculture, irrigation, drinking water, coastal infrastructure, coastal ecosystems and coastal economic systems.
This study signifies that climate changes and risk management ,Geo disasters and Tsunami education is needed for mitigating potential Geo-marine risks in this region for capacity building for climate changes and rehabilitation issues based on local resources. The paper will also explore the issues concerned with achieving environmental, social and economic sustainability through corporate strategies and innovative geosciences information delivery and Tsunami education for the affected communities. The paper also discusses role of information technology and its application for marine hazards; risk management and sustainability aspects that deal with coastal resources development, management and Tsunami disaster management planning.
