GHG EMISSIONS AND WATER QUALITY:EXPERT DISCUSSION
UNESCO/IHA research project on the GHG status of freshwater reservoirs
UNESCO/IHA research project on the GHG status of freshwater reservoirs
Need for a GHG Reservoir Screening Tool
Address concerns around GHG emissions and mitigating climate change
Consistent and reliable approaches
Better communication of the potential climate impact of reservoirs
Identify and consider multiple services provided by reservoirs and allow more informed decision making
UNESCO/IHA research project on the GHG status of freshwater reservoirs
Objective of the GHG Reservoir Screening Tool
Net emissions methodology (IPCC SRREN 2011)
Build on latest research and data available to identify relevant variables and develop;
Highlight and identify GHG risk factors
Simple screening tool with wide application
Provide a fair and balanced way of allocating net emissions from a reservoir
UNESCO/IHA research project on the GHG status of freshwater reservoirs
Key Challenges
Implementable Acceptable
Gaining consensus - assumptions and dealing with uncertainty
Defining risk factors where there are gaps in current state of knowledge
Practical application and flexibility to adapt
