    Development of a comprehensive resilient strategy towards climate smart coastal villages through wetland management and aquaculture at Edakochi village in Ernakulam district
    (Academy of Climate Change Education and Research, Vellanikkara, 2018) Haritha, J; Zacharia, P U
    Regional small wetlands are highly significant for ensuring village level nutritional security as it provides habitat aquaculture. The work mainly focuses on developing a framework for monitoring regional small wetlands through Android App and Portal. The online platform shall be an interface between users (farmers, testing agencies), experts (scientists) and admin (ICAR-CMFRI). The App and Portal focus on strengthening the national small wetland point source database through generation of additional data sets such as water quality profile, sediment quality profile and species profile. The work provides a basic structure for uniform wetland datasets. A wetland was selected at Edakochi village, Ernakulam, Kerala as representative to generate few among the data set. Wetland map of Kochi Taluk was created using QGIS which depicts extend of spread of water bodies. Restoration of the selected wetland was carried out viz side bund strengthening and sluice gate fortification. Water quality before and after restoration was assessed and water quality was found to be improved after restoration. The wetland has been restored and made suitable for aquaculture which could be further carried out by stake holders. Geospatial analysis of the selected wetland viz catchment area, elevation, slope, flow accumulation and drainage were done. The datasets generated could be fed to the online portal or app and the model could be replicated across all regional small wetlands so as to enhance the small wetland resilience.

    Documentation and validation of biotic and abiotic Indicators used by farmers for weather prediction in Wayand district, Kerala
    (Academy of Climate Change Education and Research, Vellanikkara, 2018) Anju, R; Binoo P Bonny
    Indigenous Technical Knowledge (ITK) is an integral part of the culture and history of a local community. It is evolved through many years of regular experimentation on the day to day life and resources available in the community. Biotic and abiotic indicators used by farmers for weather prediction are the parts of the ITK. Twenty abiotic indicators and thirty-five biotic indicators were documented in this study. The documented indicators were validated through farmer participatory process using Use Validity Score (UVS) and through published research findings. Based on UVS, four abiotic and eight biotic indicators could be grouped under high UVS category (>2.80 and > 2.56 respectively). The abiotic indicators with high UVS were mostly based on general observations of common natural features. As the difficulty of observation increased in terms of requirement of specific details, the popularity of indicators showed a decreasing trend towards medium to low levels. Abiotic indicators with high UVS in the order of ranks were clear blue sky related to no rainfall (3.33 UVS) followed by thunder and lightning with UVS 3.15 and dark rolling clouds along with cool breeze (2.94), both related to imminent rainfall. Among biotic indicators, all the three top ranked indicators were used for the prediction of rains and were associated with swarming of winged termites in the evening, frogs croaking near swampy areas in groups and grey wagtail flying down to the earth in groups with UVS 3.03, 3.00 and 2.92 respectively. Thematic content analysis based on published theories and related research validated eight abiotic and four biotic indicators scientifically. Most important inference from the study was that, people still relied on ITKs for weather prediction and were depended on simple observations related to common natural features. Moreover, the farmers’ access to formal meteorological forecasts was limited to mass media sources. Customized crop-based weather forecast that promotes integrated use of popular ITKs, can improve the efficiency and reliability of the weather forecast among farmers.

    Climate change and population connectivity of Lakshadweep atolls
    (Academy of Climate Change Education and Research, Vellanikkara, 2018) Athira Prasad; Sreenath, K R
    Lakshadweep is the only atoll type reefs in the territory of India. Since Indian Ocean is the warmest among tropical oceans, Indian corals reefs are vulnerable to the impact of climate change. Coral connectivity helps in maintaining the resilience capacity of sensitive coral reefs. However, shifts in global temperature will strongly influence the period of larval duration and hence the connectivity between the reefs. This study utilised the Mann Kendall trend analysis and Empirical Orthogonal Formula to study the trend of sea surface temperature and salinity over the region. Current study revealed a warming trend of sea surface temperature of Lakshadweep waters. Empirical orthogonal function indicates opposite temperature and salinity modes in the Indian Ocean region which encompasses the Lakshadweep waters. Spatio temporal dipoles identified are surmised to be due to the influence of global climatic phenomenon like El Niño and Indian Ocean Dipole. The study also tries to understand the relationship between larval connectivity and climate. Our findings implies that climate change has a significant influence on larvae and in turn affecting the journey to their corresponding settlement reef. Resilient reefs act as the source for seeding the bleached or destroyed reefs by larval dispersal. Knowledge on the changes of larval connectivity between the reefs can help in taking important decisions during the interpretation and implementation of resilience based management tools in a coral reef. Identifying the pattern of settlement and population connectivity supports in making new Marine Protected areas.
