Water‐saving irrigation is essential for crops in saline regions where freshwater resources are scarce. We tested furrow irrigation methods and planting techniques in terms of yield, water savings, water productivity (WP), soil salinity (EC e ) and soil water content (SWC) for sunflower in saline soils. Planting on the top of the ridge (T) or side slope on the ridge (S) were tested in factorial combination with (i) skip fixed...

Quantitative data on coastal land use changes are essential for effective resource management and sustainable development. In this study, we examined land use and land cover (LULC) changes, along with erosion and accretion, in the climate-sensitive Sundarbans of India using satellite imagery from 1973 to 2022. Over this period, approximately 478 km 2 of land was lost to erosion, while 408 km 2 were gained through accretion. Al...

The Sundarbans mangrove ecosystem, the world’s largest contiguous mangrove forest, is under pressure from changing salinity due to climate change, reduced freshwater input from upstream rivers, and tidal dynamics in the Bay of Bengal. Despite its ecological and socio-economic significance, previous studies have not provided a comprehensive, location-specific assessment of salinity that explicitly links spatial heterogeneity wi...

Global climate models (GCMs) are essential for projecting future climate changes, yet their ability to accurately simulate extreme precipitation, particularly in South Asia, remains a major challenge. This study assessed the performance of GCMs from CMIP5 and CMIP6 in replicating 11 extreme precipitation indices, using ERA5 data from 1975 to 2005. The results revealed substantial variability across individual models, with CMIP...

Access to irrigation water is pivotal for dry season crops in the coastal saline regions of Bangladesh. This research investigates strategic measures aimed at ensuring water availability for polder agricultural purposes in the dry season. This study was performed from 2017 to 2022 to assess the water availability inside polders # 30 and # 31 in Khulna region of the south‐western coastal zone of Bangladesh. Our methodology enco...

Pumping groundwater for irrigation in Bangladesh is a major energy-consuming process and mostly depends on diesel fuel, which is related to greenhouse gas (GHG) emissions. But that issue has not yet been addressed in Bangladesh. `In this study, we have estimated GHG emissions for dry season (DS) irrigated rice considering all irrigation devices with their lifting heads, area coverage, and water sources (surface and groundwater...
