Food security in Bangladesh, with particular reference to rice and wheat was investigated by examining trends in yields, area of cropping and overall production in recent decades. Prospects for continued increases in yield and area of the different rice crops and of wheat, considering the impact of climate change, suggest that continued large increases in(More)
Sustaining irrigation is vital for ensuring future food security in the face of population growth and a changing climate in Bangladesh. In this study, a daily soil water balance simulation model was used to estimate the net irrigation requirements of nine crops including Boro rice for the historical period of 1985–2010 and for future climate scenarios of(More)
Globally, irrigation accounts for more than two thirds of freshwater demand. Recent regional and global assessments indicate that groundwater extraction (GWE) for irrigation has increased more rapidly than surface water extraction (SWE), potentially resulting in groundwater depletion. Irrigated agriculture in semi-arid and arid regions is usually from a(More)
