Featured Ensuring Justice in Climate Legacy of Bangladesh - an Evaluation View Digital Media
Paper Presentation in a Themed Session Md Abdul Awal Khan
The adverse effects of climate change on the human rights of the marginalized population create worsen situations of climate injustice. Climate justice integrates protection of the climate vulnerable people, environmental sustainability, and effective environmental governance. The concept of climate justice or injustice due to climate change has not been popularized or largely addressed both nationally and internationally. Despites significant normative development of Bangladesh addressing climate change, establishing climate justice in the law and policy measures remains inadequate. Therefore, to address the normative gap of climate justice, a systematic human rights-based approach is essential. The paper primarily focuses on climate literature to understand the systematic development of climate justice and human rights for the protection of present and future generations in Bangladesh. This study also investigates application of international principles of environmental law to climate justice in the context of Bangladesh. Moreover, shortcomings and gaps in the existing normative framework of climate justice are also identified. Further, viable options to address climate justice and human rights debates are also highlighted.
Projected Evapotranspiration Using WEAP Model Under Shared Socioeconomic Pathways Climate Change Scenarios: A Case study in Karkhe Basin, Iran View Digital Media
Paper Presentation in a Themed Session Nozar Ghahreman
Evapotranspiration is important in agricultural water management especially in water scarce regions. The current research assesses the performance of the water management model WEAP for projection of potential evapotranspiration in Karkhe Basin, southwest of Iran. The model was run using projections of two climate model under SSP2-4.5 and SSP5-8.5 climate change scenarios. The required observed meteorological data of selected synoptic stations located in the study basin were collected from Iran Meteorological Stations and used to estimate evapotranspiration using FAO-Penman Monteith equation. These obtained values were used as an evaluation measure of WEAP model performance in estimation of ET. Projected values of potential evapotranspiration using KIOST-ESM and MPI-ESM1-2-LR from CMIP6 project under SSP2-4.5 and SSP5-8.5 scenarios for future period of 2020 to 2100 were retrieved from ESGF climate database and the bias was corrected using delta method. Then these projected values of ET were compared with FAO-PM equation estimations using future period climate data under both climate change scenarios. The corresponding values of RMSE for two models of KIOST-ESM and MPI-ESM1-2-LR under SSP2-4.5 و SSP5-8.5 scenarios were 0.5,0.63.1.09,1.05 respectively which shows higher accuracy of KIOST-ESM model. Among the study stations best performance in ET projection under both scenarios using KIOST-ESM was observed in Khoramabad with RMSE 0.44. for the MPI-ESM1-2-LR model under both scenarios, the highest agreement between projections and estimated values using PM equation was observed in Asadabad station with RMSE values of 0.52 and 0.45 for two scenarios, respectively.
