Aims: The aim of the study is to find out the effect of climate induced changes in the ecosystem services of Chilika Lake of Odisha. Study Design: The study has been conducted in Chilika Lake, including the peripheral districts Khurda, Puri and Ganjam. Secondary data have been used for rice yield, fish production and for various weather parameters. Methodology: The statistical analysis like Mann-kendall’s test is used for trend analysis, Fixed panel data regression to find out the influence of climatic parameters on yield of paddy and multivariate multiple regression to study the effect of climate change on fish production has been used. Results: The fixed effect model was found relevant during panel data regression. The weather parameters annual mean rainfall and soil profile moisture were found positively significant at one per cent level of significance in influencing the yield of paddy. Whereas annual mean temperature, squared rainfall and root zone wetness were found negatively significant. Both the temperature and root zone wetness were significant at one and five percent level of significance respectively. Squared rainfall term is found negatively significant at the five percent level of significance which shows a quadratic relationship between rainfall and yield. The estimates of fish production, shrimp and crab production in the Chilika lake revealed that the water salinity and water temperature were found significant at five and ten percent level of significance respectively in the case of fish production. The water salinity founded negatively influences fish production. There were no parameters were found significant in the shrimp production in the lake for the period of 2000 to 2015. The variables water pH and dissolved oxygen were found positively significant at ten and five percent in influencing the Crab production of the lake. The parameter water transparency was found insignificant for all three independent variables viz. fish, shrimp and crab production. Conclusion: It is found that annual mean rainfall and soil profile moisture have a significant positive influence of paddy whereas temperature and root zone wetness have a significant negative influence on paddy yield. Only water salinity was found negatively significant for fish production. The parameters, water pH and dissolved oxygen were found to have a positive influence on Crab production in Chilika lake.

The aim of the study is to identify various adaptation strategies of farming communities under climate-induced changes in the wetland and to estimate the parameters involved in determining the strategies. The study was carried out in Chilika lake including the peripherals districts Khurda, Puri and Ganjam of Odisha. Primary data of 120 farmers across different sectors and secondary data pertaining to natural calamities occurred in the area has been used for the analysis. Probit analysis was used to estimate the parameters and its marginal effects on different adaptation strategies being identified. Among the farming community water conservation methods entailed, Integrated farming system, institutional aids, agronomic measures and cultivation of climate resilient varieties, identified as major adaptation strategies. It was discovered that 62.5 per cent of the farmers were going for climate resilient varieties, especially salt, drought and pest tolerant varieties. About half of the farmers were adopting agronomic measures to cope with climate change. Almost 60 per cent were depending upon institutional aids for various adaptation practices as well as gathering information for preparedness against any natural calamity. Less than half of the farmers responded that they were practicing integrated farming system and using water saving techniques against uncertainties in the weather. The model revealed that age, education, landholding, income from wetlands, Income from other sources and level of awareness were found to have a significant role in going for various adaptation strategies. This study provides understanding of adaptation decisions adopted by farmers of Chilika.
