“…Moreover, in the southwest region of Bangladesh, more than 70% of the population is dependent on unprotected sources, such as rainwater, rivers, canals, and ponds as their source of drinking water ( Islam et al., 2013 ; Hoque et al., 2016 ). Also, salinity intrusion in the drinking water of coastal areas is one of the consequences of climate change, which is accelerated by sea-level rise, cyclone, and excessive withdrawal of freshwater (M. H. Hasan et al., 2020 ; Vinei et al., 2011 ; Chowdhury and Hossen, 2017 ). In Batiaghata and Koyra, the majority of the respondents collect their drinking water from the shallow tube-wells, and they are facing scarcity of freshwater due to salinity intrusion, which agrees with the study conducted by Khan et al.…”

Every year thousands of people are being displaced in coastal areas of Bangladesh due to natural calamities associated with climate change, known as Internally Displaced Peoples (IDPs). Climate change adaptation measures play a significant role in coping with the alteration of climatic components, while various forms of barriers hinder the sustainability of adaptation. This research was conducted to understand the perception of IDPs on climate change impact on health in the coastal areas of Bangladesh, including the adaptation practices and barriers to the coping strategies. To fulfill the objective, 420 individual surveys were conducted randomly in two Sub-districts of Khulna district in Bangladesh. The findings reveal that the riverbank erosion and cyclones were the primary reasons for displacement, and the social relationships were hampered in the new places of living. Also, the temperature in summer and winter, and the rainfall intensity increased, whereas rainfall slightly decreased over the last ten years. Differences of opinion were identified about the effects of the changing climatic variables on the respondents' health between the previous and present locations. Despite practicing different adaptive strategies, the weak financial condition and a lack of access to health care information are mostly hindering the sustainability of adaptation. This research may help policymakers in taking proper initiatives to ensure sustainable adaptation practices in the coastal areas.

“…This delta has a unique ecosystem characteristic comprising the three mighty river systems (Ganges-Brahmaputra-Meghna) enclosed by the terrestrial, aquatic and marine ecosystems [44]. The city Khulna is located in the lower part of the Bengal Delta frequently stressed by tidal surge related inundation, salinity intrusion, tropical cyclone and hydro-climatic variabilities [44][45][46][47][48]. The city is highly dependent on peri-urban agriculture for its food supply.…”

Role of Information in Farmers’ Response to Weather and Water Related Stresses in the Lower Bengal Delta, Bangladesh

et al. 2020

Farmers in the lower Bengal Delta around the city of Khulna, Bangladesh, are particularly vulnerable to hydro-climatic variability. Phenomena such as heavy rain, drought and salt intrusion increasingly affect their crop production, with far-reaching socio-economic and environmental impacts. Reliable hydro-climatic information service received in a timely manner could help farmers improve their responses to hydro-climatic variability, thus improving their agricultural decision-making. However, significant challenges persist regarding information uptake and the role of information from the available sources. We designed an explorative research framework combining different participatory methods and analysis of climate data. Our aim was to examine three key research questions: (i) what information is currently available to farmers for agricultural practices and decision-making? (ii) what is the perceived quality of the available hydro-climatic information in response to water and weather related stresses? (iii) how does the available information influence farmers’ decision-making? We found that farmers had access to information from five main sources: informal contacts, formal contacts, education and training programs, traditional media (like television) and modern ICT tools/social media. However, informal contacts, particularly with peer farmers and private input suppliers, were the farmers’ main source, in addition to their own previous experiences. Farmers perceived hydro-climatic variability as high and the quality of available hydro-climatic information as poor. They indicated a need for more accurate, time-specific, trusted and actionable information for improving agricultural decision-making. We conclude that there is high potential and need for hydro-climatic information services tailored for farmers in the study area.

“…However, these deltas have been recognized as the main places for significant land use and land cover (LULC) changes due to population growth, urbanization, anthropogenic activities, and socioeconomic development [2]. Over the last decade, these changes have affected various global issues, both positive and negative, including terrestrial ecosystems [3], land surface temperatures [4], regional climates [5], soil quality [6], hydrological regimes [7], flooding [8,9], other natural hazards [10,11], and especially food security [12,13]; therefore, studying LULC changes and assessing driving factors to balance the correlation between the human needs and negative consequences are vital factors for sustainable development [14]. For the world's third-largest delta, the Mekong River Delta, the LULC has changed tremendously over the last four decades due to socioeconomic developments [15].…”

The main purpose of this paper is to assess the land use and land cover (LULC) changes for thirty years, from 1990–2020, in the Dong Thap Muoi, a flooded land area of the Mekong River Delta of Vietnam using Google Earth Engine and random forest algorithm. The specific purposes are: (1) determine the main LULC classes and (2) compute and analyze the magnitude and rate of changes for these LULC classes. For the above purposes, 128 Landsat images, topographic maps, land use status maps, cadastral maps, and ancillary data were collected and utilized to derive the LULC maps using the random forest classification algorithm. The overall accuracy of the LULC maps for 1990, 2000, 2010, and 2020 are 88.9, 83.5, 87.1, and 85.6%, respectively. The result showed that the unused land was dominant in 1990 with 28.9 % of the total area, but it was primarily converted to the paddy, a new dominant LULC class in 2020 (45.1%). The forest was reduced significantly from 14.4% in 1990 to only 5.5% of the total area in 2020. Whereas at the same time, the built-up increased from 0.3% to 6.2% of the total area. This research may help the authorities design exploitation policies for the Dong Thap Muoi’s socio-economic development and develop a new, stable, and sustainable ecosystem, promoting the advantages of the region, early forming a diversified agricultural structure.
