[Display omitted] • A framework incorporating the elasticity-based Budyko approach is developed to identify the hydrologic sensitive and resilient catchment. • The catchment characteristics are portrayed in light of the hydrologic response variation and climate change. • The developed approach of sensitivity and resiliency analysis is further explored in updated CMIP6 future climate scenarios. To develop effective adaptation strategies for climate change, particularly in regions where water is scarce, it is crucial to comprehend and quantify how hydrological responses are influenced by anthropogenic activities and climate change. The primary concern nowadays is to identify the hydrologic sensitive and resilient catchment under these diverse conditions. Thus, a framework is developed in this study to analyse the hydrologic sensitivity and resiliency of a catchment incorporating the elasticity-based Budyko approach. The developed framework is applied to three neighbouring catchments (Brahmani, Baitarani, and Subarnarekha) in eastern India that have received less attention in light of resiliency and sensitivity perspectives. The Budyko approach is first applied using hydro-climatic records of historical phase (1979–2018) and then extended for future phase (2025–2064) under four different Shared Socioeconomic Pathways (SSPs) (1-2.6, 2-4.5, 3-7.0 and 5-8.5) of Coupled Model Intercomparison Project Phase 6 (CMIP6) projections which will provide new insights to the hydrological community. The results highlight that streamflow variations of the Subarnarekha is more sensitive to anthropogenic activities in all time phases. In contrast, the Brahmani and Baitarani are more sensitive to climate change in future phases. During historical phase, the Brahmani and Baitarani are identified to be resilient catchments with high water yield and dry climate, whereas the Subarnarekha is found to be sensitive catchment, exhibiting low water yield and dry climate. However, in future phase, all three catchments are predicted to be resilient, characterized by high water yield and wet climate. The major inference from this study is excess anthropogenic activities can disrupt the anticipated hydrological functioning of a catchment, particularly under critical climatic conditions, which can result in decreasing hydrological resiliency. The finding of this study mainly highlights the response of a hydrological system to climate change and anthropogenic activities to explore the approach of sensitivity and resiliency from a socio-hydrological perspective.

Abstract: The marine based algal biofuel may be the best possible options for future energy, particularly for India where freshwater and land resources are limited. We have characterized a novel marine microalga, isolated from an Indian Ocean using genotypic and biochemical studies, which contain high lipids (48%) on dry wt. basis, among marine-microalgae reported from the Indian subcontinent. The classification of new species based on DNA barcodes studies using 16S rRNA and 23S rRNA has indicated its genetic similarity to green algae Parachlorella kessleri. Subsequently, FAME analysis has showed that it contain about 43%, saturated fatty acids, which makes new algal species highly suitable for further exploration and commercial production of the biodiesel.
