As a result of COVID-19 spread, Bangladesh implemented a range of measures including general holidays, lockdown, no lockdown, and strict lockdown which resulted in the dramatic ups and downs of the price level of the products. This study aimed to examine the influence of COVID-19 on poultry products (meat and eggs) in Bangladesh using Gazipur-an intensive poultry growing area - as a case study. Monthly market price data of poultry meat and eggs, and primary panel data from the same respondents using a random sampling technique through a structured questionnaire-based interview, Focus Group Discussion (FGD), and Key Informant Interview (KII) were collected. The results reveal that after the incidence of COVID-19, the price of poultry products at farmgate, wholesale and retail levels dropped drastically for the first three months (February to April 2020). Following that, the market price of farm (broiler) chicken and eggs increased by 40% and more than 30%, respectively. On the other hand, the price of local ( deshi ) chicken increased by 15%, which was already high on the market. However, in the early phase of COVID-19, many smallholder poultry farmers and hatchery owners were forced to shut down due to less demand/no demand of the product along with high feed cost and inadequate support from external sources. The government should provide financial support with low or no-interest rate to the smallholder growers in order to enhance their resilience against shocks like COVID-19 pandemic, natural disasters, etc., Competing Interests: The authors declare no competing interests., (© 2023 The Authors.)

As transition areas between aquatic ecosystems and the adjacent terrestrial ones, riparian regions are highly exposed to coastal climate hazards. This article describes how climate change and extreme weather impact vulnerable riparian communities and settlements. The analysis is done by reviewing past research and empirical case studies from riparian rural communities of the impact zone of the Sundarbans in Bangladesh, the world's most extensive mangrove forest. The article discusses the climate-related impacts on households through a Severity Index of Vulnerability and assesses the adaptation responses they may pursue. The principal climate-related vulnerabilities and impacts due to increases in temperature, storm surges, sea flooding, and sea-level rise are seawater intrusion and riverbank erosion. Many households have adopted several autonomous reactive adaptation strategies rather than planned ones, to cope with these impacts. However, government organisations and NGOs provide less than optimal technical and financial support to households for planned and anticipatory adaptive responses. The main barriers to adaptation were the high cost of improved crop varieties, inadequate agricultural extension services, and a lack of knowledge on effective climate adaptation. The restoration of the mangrove ecosystem may increase its resilience and, among other things, make local communities less exposed. The article also presents some adaptation measures proper to reduce the climate-related vulnerability of riparian settlements., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2022 Leal Filho et al.

•This study estimates economic returns to investments in rice varietal development in the Philippines and Bangladesh.•The net returns to IRRI and national partners' investments remain strongly positive.•However, the returns are decreasing at a faster rate in the Philippines (24%) than in Bangladesh (6%).•IRRI and national partners should continue investing in rice R&D, especially to develop superior rice varieties., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Authors.)

Bangladesh is one of the most climate-vulnerable countries globally, where the livelihood of agro-based dependent people became vulnerable due to different natural hazards, especially in the southern coastal part. This study investigates the influence of climate change on household vulnerability and income diversity, data collected from the climate-vulnerable coastal areas of Bangladesh. Both panel data regression and structural equation model were employed to examine the vulnerability status, whereas income diversity was measured through diversity index and "Type-66" livelihood strategy. Results reveal that sources of income have diversified over time. However, the study also reveals that climate change-especially the increase in salinity has affected crop production, resulting in increased income vulnerability of small and marginal farmers who are highly reliant on farm income. Moreover, findings reveal that climate change has influenced households to diversify into low-income sources that do not help to overcome their income vulnerability. Therefore, a cooperative land management system, establishment of embankment, training, and skill development programs are needed to generate feasible alternative income sources to improve the livelihood of coastal people., Competing Interests: The authors declare no conflict of interest., (© 2021 Published by Elsevier Ltd.)

Women's empowerment has a great influence on health, nutrition, education, and the overall well-being of societies as well as of the children and households. This study investigates the effect of women's empowerment on poverty reduction and focuses on household deprivation, in terms of education, health, and standard of living. Primary data was collected from 914 married women from rural areas of Bangladesh using a well-structured questionnaire and a random sampling technique. Descriptive statistics, logistic regression, and ordinary least squares models were used in this study. The results indicate that increased women's access to education, asset ownership, decision-making power on children's health and education, and access to medical facilities, have caused a significant decline in income poverty and multidimensional poverty. However, gender violence, taking resources against women's will, and preventing women from working outside, have caused a considerable decline in per capita income and an increase in income poverty and multidimensional poverty. Overall, it is found that women's empowerment has a great impact on the reduction of income poverty and multidimensional poverty in society. The findings of the study can assist and guide policymakers to initiate appropriate strategies for women's empowerment to reducing poverty in Bangladesh while making progress towards other social and developmental goals.

In Bangladesh, the COVID-19 pandemic is likely to have substantial effects on the livelihood of people, but smallholder vegetables growers will be even more affected because of the perishability nature of the product. The first case of COVID-19 was confirmed in Bangladesh on 8th March, 2020 and consequently the country went into lockdown on 26 March, 2020. This study has made a survey of vegetables farmers through a mobile phone to understand the impact of COVID-19 on vegetables supply chain, gross margin and the future production plan of the growers. In Bangladesh, the lockdown has disrupted the food supply chain and increases the likelihood of food insecurity. Lockdown has impeded vegetable farmers' access to markets, thus limiting their productive and sales capacities. The price of yield has dropped by more than half resulting in huge loss for vegetable growers. The loss incurred by the farmers for producing Brinjal, Cucumber, Pointed gourd, Yardlong beans and Bottle gourd are BDT 4900, BDT 10900, BDT 57400, BDT 52500 and BDT 18500 per acre respectively as a result of COVID-19. The decreased income increases farmers' likelihood of vulnerability and food insecurity and poses a challenge to continued produce. 'Cash support' is more important than 'food support' in order to keep vegetable farmers in farming, to ensure a ready supply of necessary low-cost resources, and to help fight against the upcoming food shortage., Competing Interests: The authors declare no conflicts of interest.

This work is intended to examine the effects of Bangladesh's subtropical climate on coronavirus diseases 2019 (COVID-19) transmission. Secondary data for daily meteorological variables and COVID-19 cases from March 8 to May 31, 2020, were collected from the Bangladesh Meteorological Department (BMD) and Institute of Epidemiology, Disease Control and Research (IEDCR). Distributed lag nonlinear models, Pearson's correlation coefficient and wavelet transform coherence were employed to appraise the relationship between meteorological factors and COVID-19 cases. Significant coherence between meteorological variables and COVID-19 at various time-frequency bands has been identified in this work. The results showed that the minimum (MinT) and mean temperature, wind speed (WS), relative humidity (RH) and absolute humidity (AH) had a significant positive correlation while contact transmission had no direct association with the number of COVID-19 confirmed cases. When the MinT was 18 °C, the relative risk (RR) was the highest as 1.04 (95%CI 1.01-1.06) at lag day 11. For the WS, the highest RR was 1.03 (95% CI 1.00-1.07) at lag day 0, when the WS was 21 km/h. When RH was 46%, the highest RR was 1.00 (95% CI 0.98-1.01) at lag day 14. When AH was 23 g/m 3 , the highest RR was 1.05 (95% CI 1.01-1.09) at lag day 14. We found a profound effect of meteorological factors on SARS-CoV-2 transmission. These results will assist policymakers to know the behavioral pattern of the SARS-CoV-2 virus against meteorological indicators and thus assist to devise an effective policy to fight against COVID-19 in Bangladesh., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© Springer Nature B.V. 2020.)
