Strategy Formulation and Adaptation Pathways Generation for Sustainable Development of Western Floodplain of Ganges

Abstract

The coastal zone of Bangladesh is very heterogeneous in nature and has marvelous potential to create opportunities of national importance and contribute to GDP. Among the potentials-intensification of agriculture, aqua-culture and marine fishery, ship building industry, eco-tourism, deep sea port etc. are most significant. Unfortunately, the coastal zone of the country is disaster prone area. Poor communication, lack of education and health care facilities, prolonged absence of safe drinking water and inadequate cyclone shelters contribute and multiply the dimension of vulnerability. Furthermore, increasing population pressure increases the competition for limited resources. As a consequence, in order to unlock these potentials, existing and new interventions are required to serve in an integrated and inclusive way; calling for a distinct and integrated coastal development strategy. This study aims to investigate the issues of the western floodplain of the Ganges and propose some identical strategies and subsequent adaptation pathways to delineate the development roadmaps to decision makers and researches. Analyses have been conducted through GIS and RS technology, Dynamic Pathway Generator, Excel analysis and field investigation.

Generic adaptation pathways for coastal archetypes under uncertain sea-level rise

“…At the same time decisions on adaptation are also driven by other incentives, such as economic development. In rural south west of Bangladesh, this triggers the implementation and development of pathways with dykes, drainage and pumps [54]. For the Mekong Delta, accommodate/retreat pathways have been explored, consisting of adapting agriculture to enhance yield, diversifying livelihoods to ensure other sources of income, and migrating to less hazardous areas [55].…”

Enabling assessment of distributive justice through models for climate change planning: A review of recent advances and a research agenda

“…This approach is often found in simulation‐based IAMs. For instance, Ahmed et al (2017) assess the performance of alternative adaptation pathways for the western Ganges floodplain based on both their effectiveness in reducing flood risk, their impacts on economic development, and their sociopolitical feasibility. The advancement in many‐objective optimization has contributed to the uptake of the disaggregated metrics approach in simulation‐optimization IAMs.…”

Accounting for Multisectoral Dynamics in Supporting Equitable Adaptation Planning: A Case Study on the Rice Agriculture in the Vietnam Mekong Delta

“…Climate change adaptation planning, however, often uses aggregated indicators, disregarding equity considerations (Kolstad et al, 2014;Stanton et al, 2009). For example, adaptation planning studies by Ahmed et al (2017); Campos et al (2016); Radhakrishnan et al (2017); Ranger et al (2013); Smajgl et al (2015) all report on aggregated indicators such as flooded area, total area having a certain salt concentration, number of people exposed to flooding, total paddy yield, and total economic value in a flood prone area. If little to no attention is given to assessing which robustness of alternative policies not only across scenarios and across dynamics over time (Hadjimichael et al, 2020;Steinmann et al, 2020), but also across people and across space.…”
