National Initiative on Climate Resilient Agriculture - CIBA

Salient findings


1.      A robust methodology was developed for the collection of data on perceived climate change events, impacts, risk assessment, vulnerability estimation, adaptations and mitigations with three stages viz., focus group discussions, stakeholder workshop and in-depth farm survey with aqua farmers.  Twenty one indicators were identified based on extensive literature survey and relevancy judgment of the experts for the calculation of adaptive capacity score in the estimation of shrimp farming vulnerability.


2.      A prototype floating chamber was fabricated to collect green house gases (GHGs) from aquaculture ponds and their quantification and Life Cycle Analysis (LCA) in aquaculture supply chain for the first time. LCA of shrimp production system indicated that global warming potential for every ton of shrimp production was mainly due to feed preparation in feed mill and energy use by water pumps and aerators during shrimp production.


3.      Actual aeration requirements in shrimp culture ponds were calculated based on sediment and water respiration rates to decrease the energy use. Farmers were using more aeration than the actual and there is a need to educate them to use aerators as per the actual requirement. This will help in not only to decreasing the carbon foot print but also in decreasing the cost of production.
