Featured Effects of Climate Change Adaption on Farmers’ Livelihood: A Case Study of Saltwater Intrusion Adaption in Central Coastal Region of Vietnam
Paper Presentation in a Themed Session Thi Dieu Linh Nguyen
This paper examines the salted water intrusion (SWI) adoption in Central Coastal region of Vietnam. We evaluate the impact of SWI adaption options on farmer’s livelihoods, using cross-sectional survey data of 414 farmers in Thua Thien Hue and Quang Nam province. Propensity-score-matching (PSM) techniques is applied to solve problem related to “self-selection into treatment”. The findings reveal a robust and significant impact of SWI adaption methods on economic indicators (crop productivity, net farm income) and social indicators (rate of kid going to school and food security). The results confirm that there is considerable heterogeneity in implementing SWI adaptation options of farmers in study area. We find that out of five adaption methods, four (vegetable, papyrus, shrimp and lotus-fish) are noted to have a quite significant income –enhancing, mainly thank to higher profits. Moreover, the household who apply these four methods have significantly higher rate of kid going to school (by 15%, 8%, 22% and 57% respectively) and ensure more food secure. Method of applying new varieties rice is recognized to have income- decreasing due to lower yield and insignificantly positive effect on social issues. The significant of results are tested by bootstrap to ensure robustness in our study.

Paper Presentation in a Themed Session Virendra Goswami
To develop Physicochemical and spectroscopic methods to characterize the in-situ chemical speciation of the inorganic contaminants and develop technologies for remediation of water & environmental pollution by catalytic oxidants. Discuss strategies to control Water & Environmental pollution resulting due to the toxin, toxic gases, GHG, by Catalytic oxides. Next, control Global Warming and save marine life by inhibiting the and remediation of the Water treatment process by making use of catalytic oxidants. The oxidation process would be employed to treat Groundwater contaminants by making use of the chemical oxidant. Also, to correlate Physico-chemical properties of these catalytic oxidants involving chemical oxidation be applied in subsurface systems and in above ground water treatment systems involving chemical oxidation regeneration of granular activated carbon (GAC). Water gets polluted due to the toxin and toxic gases. There are four types of toxic entities; chemical, biological, physical and radiation In order to control marine environmental pollution, subsurface systems and in above groundwater treatment systems, the present investigations are focused to develop innovative methods to entrap toxins , Chemical toxicants include inorganic substances e.g. lead, mercury, hydrofluoric acid, and chlorine gas, byHigh Affinity Toxin Receptors (HART) & convert GHG (Methane, CO2, ) to ethanol by catalytic processes. Next evaluate the correlation of chemical oxidants with chemical species associated with soil and aquifer materials, and with target and non-target contaminants during water treatment processes. Finally, efforts have been made to develop Correlational Predictive Model of Chemical Reaction Kinetics in order to investigate process fundamentals & assess contaminant transformation.
Assessing the Impact of Cyclone Amphan on the Microclimate of Botanical Garden in Shibpur View Digital Media
Paper Presentation in a Themed Session Sudeshna Haldar, Saikat Kumar Paul
Global warming causing rapid rise in temperature is a major cause of concern. Several studies have highlighted the impact of vegetation on microclimatic regulation. The microclimate of a region regulates the thermal comfort level of dwellers. This study develops a framework to investigate whether the settlement near the age old ‘Acharya Jagadish Chandra Bose Indian Botanic Garden’ in Howrah district of West Bengal, India, covering an area of 270 acres, enjoys a microclimate which is affected by the wide range of vegetation of this garden and the river Ganga, by inferring radius of influence of cooling effect of the garden. This study is set out to also explore the changes that took place in local microclimate of the region near the garden after the super cyclone ‘Amphan’ struck the city between 16th to 21st May 2020. Amphan has caused a large scale destruction of trees in the botanical garden. The results of this analysis illustrates the effect on microclimate change, by establishing a correlation between LST (Land Surface Temperature) and NDVI (Normalised Difference Vegetation Index) of the garden, from satellite remote sensing observation, using pre and post event data. The significant observation of this study is that a large vegetation reserve in an urban setup, has an impact on the local microclimate and lowers the temperature in immediate neighbourhood. Thus maintenance of the existing garden is highly recommended to establish bioclimatic comfort in the urban settlement within the radius of influence of PCI of the garden.
The Impact of Climate Change on Crop Yield: Irrigated versus Non-irrigated View Digital Media
Paper Presentation in a Themed Session Sadia Shammi
Climate change is a global issue and many studies are currently focusing on the global scale to draw the impacts of climate change on the environments and its components. Rather than the global scale, in this study, we are focusing on the regional scale to show the climate change impacts on food production, specifically crop yield. We are proposing a linear and multilinear regression spatiotemporal model which shows the climatic impacts on crop yields. As a representative of a regional scale, we studied Mississippi state’s soybean production which contributed about 2.49 % in 2018 and 2.2 % in 2019 of the total US soybean production. To draw the climate impacts we categorized the crop zone into the irrigated and non-irrigated zone and different climatic parameters i.e. maximum temperature, mean temperature, minimum temperature, and precipitations are used to model the climatic impacts on crop yield. Our proposed different spatiotemporal models showed a 24% impact on the irrigated zones' crop production and a 14% impact on the non-irrigated zones' crop production based on the agricultural districts. We found a significant negative impact on the crop yield due to the seasonal maximum temperature increase. However, the change in precipitation pattern has no consistent impact on crop yield reduction. The consecutive increase in seasonal average and minimum temperature will also have a future negative impact on crop production. This study is helpful to show a future scenario and negative impact of climate change on food production.
Sea Level Rise and Its Impacts on Indian Coastal Cultural Heritage: Irreplaceable Historical and Cultural Heritage of Mumbai View Digital Media
Paper Presentation in a Themed Session Kamlesh Gade
Anthropomorphic sea level rise is a major cause of concern resulting in loss of land area, erosion of existing built systems and a danger to ecological resources. In addition to this it will also pose a great threat to loss of cultural heritage that are linked with the coastal history of many countries, like indigenous and colonial forts, fishing communities, and religious buildings. GMSL is expected to rise by an estimate of 1.2-3 meters over the next 50-80 years and the estimations are rising with new advancements in climate change research. With these rising levels, tidal activities etc there is an impending threat of erosion and submergence of these local, irreplaceable coastal heritage. Without the correct measures in city infrastructure planning, coastal reforms and urban design, the future of these important markers is at risk. There is an immediate need to identify the various vulnerable built and un-built cultural spaces and activities, the intensity of impact to these resources and probable measures of mitigation.
Analysis Of Carbon Credit Trading Practices In Manufacturing Organizations In British Columbia Canada View Digital Media
Paper Presentation in a Themed Session Ajay Garg
Climate change is a growing fear of the public. Carbon credits (carbon offsets) that reflect the omission of a carbon dioxide equivalent from the atmosphere, such as investing in new renewable energy, can meet this challenge. In essence, “carbon credit” is a phrase used to represent a regulation by the government used to decrease the amount of carbon dioxide and greenhouse gas emissions (GHGs) (any natural or man-made gas that absorbs atmospheric infrared radiation) by industry and other organizations. Organizations that regulate emissions of GHGs may receive carbon credits that permit them to emit to a specified level of GHGs. Companies get a set number of credits, which decline over time. They can sell or trade any excess to another company. Thus, "cap-and-trade" is an incentive to reduce emissions. Government, industry, and private people in Canada can buy carbon credits to regulate emissions of GHGs. Methods that organizations implement to explore trading carbon credits are examined in this article. Factors related to carbon credits related to the profile of Canadian organizations (such as avoiding carbon taxes, international expansion, venture capital, competitive advantage, clean technology) are then discussed. The survey findings (questionnaires) and statistical analysis of 14 Canadian companies in British Columbia (150 participants) indicate that the second variable (international expansion) has maximum influence on the number of carbon credits traded by these organizations.
