Rice intensification in Bangladesh improves economic and environmental welfare

Identifying Dry-Season Rice-Planting Patterns in Bangladesh Using the Landsat Archive

“…We found that, the HTS-VIs model has the potential to map rice production across fragmented landscapes and heterogeneous production practices with comparable results to other model and governmental estimates but without local management or in situ information as inputs. The HTS-VIs model identified 4.285, 4.425, 4.645, 4.117, and 4.407 million rice-producing hectares for 2014, 2015, 2016, 2017, and 2018, respectively, which correlates well with national estimates by BBS. Moreover, the results relate strongly with the BBS district estimates of rice area with an average R-squared of 0.88.…”

“…Following model fitting, we first limit the analysis to the dry season (boro) by using only the fitted HTS-VIs results between 1 November and 31 May, which accounts for potential early planting in some areas and late harvest in others for a maximum length of the boro season across the entire country [4,25,47,59]. Then, we impose a rule-based algorithm on the resulting time series in order to identify rice from 2013-2018.…”

“…In recent decades, Bangladesh has made substantial progress in reducing lean season impacts on food security through the introduction and widespread adoption of a second season of irrigated paddy rice production, which primarily consists of high-yielding variety (HYV) rice [3]. Additional production in the dry season has made major contributions toward self-sufficiency in rice supplies for the country as a whole and has reduced the occurrence of a lean season in some regions [4]. However, volatility in rice markets, increasing pressures on arable land from population growth and climate change, and changing management practices and technologies continue to create barriers for sustaining rice self-sufficiency in Bangladesh [2].…”

Scientific support of the rice growing industry of the agroindustrial complex of the Russian Federation in solving the problems of food security

“…In many countries of the world, in particular, in China, Bangladesh, breeding work has recently been carried out to create rice hybrids that have some form of resistance to biotic or abiotic stresses and are more responsive to fertilization and use of water resources [6].…”

Challenges and opportunities in productivity and sustainability of rice cultivation system: a critical review in Indian perspective

“…From 1998 onwards, Bangladesh witnessed a noble growth in rice yield, surpassing India and Pakistan, and continues to uphold the growing trend. It was due to intensive use of modern technologies such as cultivation of high-yielding varieties, adoption of improved irrigation technologies and balanced fertilizer application (Ahmed 2004;Shew et al 2019). In past few years, rice productivity in India looks stagnant, even it may decline in future due to over-exploitation of natural resources (Ladha et al 2009), low seed replacement rate (UPSDR 2019), poor management of irrigation water, fertilizer and crop residue (Ladha et al 2009), same cropping pattern over the years (Nambiar and Abrol 1989) and lack of awareness about consequences of faulty cultivation practices among farmers (Dis et al 2015;UPSDR 2019).…”
