“…For example, more than 30% of the 700 million low-income families in Asia, including Bangladesh, are in rain-fed lowlands that are impacted by environmental triggers [19]. Changes in meteorological variables such as rainfall, temperature, and humidity, as well as natural disasters such as cyclones, floods, drought, etc., cause differences in rice production across the country [20,21]. Therefore, there is an urgent need to depict the regional rice cultivation scenario to ensure the future sustainability of the rice sector.…”

Technological advancements have long played crucial roles in rice productivity and food security in Bangladesh. Seasonal variation over time and regional differences in rice production, however, pose a threat to agricultural sustainability but remain unexplored. We performed a spatial-temporal mapping of rice cultivation area, production, and yield from 2006–2007 to 2019–2020 using secondary data for disaggregating 64 districts in Bangladesh. Growth and multivariate approaches were employed to analyze time-series data. Results showed that Mymensingh had the highest rice cultivated area and production, while Bandarban had the lowest. The 14 years highest average rice yield was found in Gopalganj and Dhaka (3.63 tons/ha), while Patuakhali (1.73 tons/ha) had the lowest. For the Aus, Aman, and Boro, the rice cultivation area in 19 districts, 11 districts, and 13 districts declined significantly. The overall rice production increased significantly in most districts. For the Aus, Aman, and Boro seasons, the rice yield in 54, 50, and 37 districts demonstrated a significant upward trend, respectively. The adoption rate of modern varieties has risen dramatically. However, there are notable variances between regions and seasons. A significant increasing trend in Aus (0.007% to 0.521%), Aman (0.004% to 0.039%), and Boro (0.013% to 0.584%) were observed in 28, 34, and 36 districts, respectively, with an increase of 1% adaptation of HYV. Predictions revealed that rice cultivation area and production of Aus, Aman, and Boro seasons will be increased in most of the regions of Bangladesh by 2030. Based on spatiotemporal cluster analysis, the five identified cluster groupings illustrated that clusters lack spatial cohesion and vary greatly seasonally. This suggests increasing rice production by expanding cultivable land, adopting high-yielding varieties, and integrating faster technological advancement in research and extension. The findings will assist scientists in developing region-specific production technologies and policymakers in designing decentral region-specific policies to ensure the future sustainability of rice production.

Market traders have recently deceived consumers about the quality and fair price of rice in Bangladesh, causing serious health concerns and unintended financial losses for consumers. Therefore, this study explores the availability, market share and concentration, and traces the varietal origin of popular rice brands on the market. Primary data were collected through an intensive survey with rice farmers, paddy and rice traders, and millers. Herfindahl-Hirschman Index (HHI) was used to estimate the market share and concentration of available rice brands. We employed a snowball sampling technique and completed 30 different supply chains as case studies to get the varietal sources of different rice brands. Results show that "BR28" was the most popular rice brand contributing about 40% of available rice in the Upazila level market, followed by "Miniket" (17.7%), "Swarna" (14.5%), "BR29" (12.1%), and "Pajam" (6.1%). Whereas, in the city markets, the contribution of "Miniket" was the highest (33.5%), followed by "BR28" (19.4%), Zira (19.2%), "Nazir" (8.5%), and "Katari" (5.2%). The traders and consumers did not confirm any specific variety against the available popular rice brands in the markets. We have explored the varietal origin by tracking the supply flow and found that the brand name "Miniket" was given by millers to each and every kind of rice that falls under the medium-slender type grain category. The market traders concentrated on producing the top 4-5 rice brands without exercising competition. Producing rice brands by over-polishing and receiving returns from by-products is indeed a double-edged benefit for the millers. Whereas, the consumers are paying more for the finer polished rice without considering the nutritional value. Therefore, strong market regulations, notably on rice milling and branding, should be enforced to protect against adverse health concerns and financial losses, and also for ensuring food and nutrition security in Bangladesh.
