Abstract

Concepts, approaches and frameworks for assessing the impacts of climate change are evolving quickly. Due to their particular geographic location, proximity to oceans, concentration of populated regions, and infrastructure, coastal communities are particularly sensitive to the effects of climate change. The present study aims to develop a thematic map based on the CID (climatic impact-drivers) framework proposed in the assessment report-6 of the Intergovernmental Panel on Climate Change (IPCC) to evaluate the climate change’s physical hazards in the coastal districts of India. The study points out that West Bengal and Odisha are the two states with the highest cyclone hazard index values making them most vulnerable to cyclones. At the same time, Kerala, Andhra Pradesh and West Bengal respectively fall in the extremely severe category of flood, heatwave and shoreline change hazards. The maritime state of Gujarat along with Diu and Daman experiences maximum severity for the sea level rise hazard. The multi-hazards index developed in the study by considering 14 threshold-based CID indices showed that the coastal state of Andhra Pradesh has the highest proneness to the physical hazards due to climate change [ABSTRACT FROM AUTHOR]

17. Potential Spatio-temporal Distribution of Invasive Charru Mussel, Mytella strigata(Hanley, 1843) Under Different Climate Scenarios

Author

Rawat, Shobha and Padua, Shelton

Abstract

Invasive alien species are a global menace to biodiversity and pose potential loss ecologically, socially, and economically. In this study, the species distribution model, Maximum Entropy or MaxEnt model was used to estimate the potential global distribution of the invasive mussel Mytella strigataunder present and future climatic conditions. Though the species is native to Latin America, its presence has been reported in several other parts of the globe, mainly due to extensive sea trade networks and the unregulated discharge of ballast water. It is posing a serious threat to indigenous species, and critical ecosystems, and the consequences can be detrimental for small-scale fisheries across the globe. The study aims to understand the habitat suitability of this species in the current situation and in the future under different climate scenarios. The study used 71 occurrence records from Global Biodiversity Information Facility (GBIF),database and 7 environmental parameters to predict its habitat suitability. According to the model predictions, the present distribution of M. strigatais expected to extend profusely to several non-native regions around the globe. While the future projections show that the area of suitability may shrink in future climate scenario Representative Concentration Pathway (RCP) 8.5 and the species will shift its distribution towards higher latitudes. This may primarily be due to human intervention, resulting in an increasing global average annual temperature. This study can help to investigate the high-risk areas under invasion by M. strigatawhich will act as an early warning system to control, prevent and regulate the further expansion of this species through public awareness and administrative action.

Abstract

Climate change and associated weather aberrations are wreaking havoc on the performance of production systems worldwide. Because of their proximity to the sea and risk of exposure, coastal wetlands are regarded as one of the most climatically vulnerable production systems. As a result, interventions to improve their adaptation and resilience to climate change are critical. We attempted to investigate the multifunctional ecosystem roles and services provided by the Pokkali and Kaipad paddy-based rotational farming systems on the southwest coast of India, which are being revived through a pilot programme implemented by the Kerala Agency for Development of Aquaculture. The physical and economic dimensions of the ecosystem services/disservices are assessed, and policy options for further land revival and area expansion of such wetlands are proposed.

Abstract

India's New Education Policy 2020, which is in tune with SDG 4 (quality education) and SDG 8 (decent work and economic growth), has stressed the redesigning of vocational education (VE) to equip the youth for the world of work, considering the window of opportunities available till 2040. Though the competence gap is being pronounced as the foremost hurdle in the 'education-world of work' transition in every sector, its precise measurement and quantification remain elusive. In this context, we have develop an innovative methodological framework and a composite index (η) to measure the competence gap of the vocational higher secondary education system (VHSES), taking marine fisheries and seafood processing courses offered under the VHSES in Kerala, India as a case study. This study demonstrates that the educational gap, delivery gap, propensity to normalize with general education and inadequate learning ecosystem are responsible for the 'education-world of work mismatch' in VE. The findings of the present study point to specific areas of VE that need pedagogic and pragmatic reconstruction. It also shows strategic policy considerations to place the learners' aspirations, gender and vocational opportunities in a balanced manner for a better vocational teaching-learning ecosystem.
