Nitrogen use efficiency thresholds for rice in Bangladesh: Evidence from large-scale farmer-managed field data

Background Nitrogen (N) over-application in smallholder rice systems reduces fertiliser-use efficiency and may increase reactive N losses and greenhouse gas emissions. However, field-scale nitrogen-use efficiency benchmarks derived from farmer-managed systems in South Asia remain...

Diurnal asymmetry in heat stress intensification across Bangladesh, 1985–2024: Accelerated nighttime warming and emerging urban risk

Bangladesh’s rapidly growing cities are becoming hotter, but how heat stress is changing over the day–night cycle has remained unclear. Using 40 years (1985–2024) of hourly Universal Thermal Climate Index (UTCI) data from ERA5-HEAT, we examined long-term changes in physiologicall...
