Assessment of Reliability of Fairly Accessible Data & Tools for Analyzing Impacts of Climate Change and Analysis of Risk of Sea Level Rise on Coastal Zone

Coast Conservation Department (CCD)

As an Island Nation in the Indian ocean, Sri Lanka coastal zone is vulnerable for the sever impacts due to climatic change but mainly due to sea level rise; Inundation, increased erosion, salinity intrusion, surges & wave over topping etc. Assessment of the hazards, vulnerabilities and risk are required for the identification of preparedness, adaptation and mitigation alternatives. But for the studies accessible and realistic data & tools should be available. Remote sensing and space based technology have become very important and timely tools for assessing coastal dynamics and related changes more easily and this project will target use of these technologies and application development within Coast Conservation Department (CCD), Sri Lanka. The objective of this prototype is the followings;

(1) Determine the availability, accessibility & reliability of data & tools for assessment of Climate Change impacts on coastal zone

(2) Execution & streamlining observations, measurements, data collection & monitoring programs at National & Regional Level for enhancing the assessment of impacts on climate change

(3) Assessment of risk on sea level rise spatially & temporally with available data
