Abstract	Precise Soil Moisture (SM) assessment is essential in agriculture. By understanding the level of SM, we can improve yield irrigation scheduling which significantly impacts food production and other needs of the global population. The advancements in smartphone technologies and computer vision have demonstrated a non-destructive nature of soil properties, including SM. The study aims to analyze the existing Machine Learning (ML) techniques for estimating SM from soil images and understand the moisture accuracy using different smartphones and various sunlight conditions. Therefore, 629 images of 38 soil samples were taken from seven areas in Sydney, Australia, and split into four datasets based on the image-capturing devices used (iPhone 6s and iPhone 11 Pro) and the lighting circumstances (direct and indirect sunlight). A comparison between Multiple Linear Regression (MLR), Support Vector Regression (SVR), and Convolutional Neural Network (CNN) was presented. MLR was performed with higher accuracy using holdout cross-validation, where the images were captured in indirect sunlight with the Mean Absolute Error (MAE) value of 0.35, Root Mean Square Error (RMSE) value of 0.15, and R² value of 0.60. Nevertheless, SVR was better with MAE, RMSE, and R² values of 0.05, 0.06, and 0.96 for 10-fold cross-validation and 0.22, 0.06, and 0.95 for leave-one-out cross-validation when images were captured in indirect sunlight. It demonstrates a smartphone camera’s potential for predicting SM by utilizing ML. In the future, software developers can develop mobile applications based on the research findings for accurate, easy, and rapid SM estimation.

Abstract	The COVID-19 pandemic has had an adverse impact on the Rohingya and the Bangladeshi host communities, which have been well documented in the literature. However, the specific groups of people rendered most vulnerable and marginalized during the pandemic have not been studied comprehensively. This paper draws on data to identify the most vulnerable groups of people within the Rohingya and the host communities of Cox's Bazar, Bangladesh, during the COVID-19 pandemic. This study employed a systematic sequential method to identify the most vulnerable groups in the context of Rohingya and Host communities of Cox's Bazar. We conducted a rapid literature review (n = 14 articles) to list down Most vulnerable groups (MVGs) in the studied contexts during the COVID-19 pandemic and conducted four (04) group sessions with humanitarian providers and relevant stakeholders in a research design workshop to refine the list. We also conducted field visits to both communities and interviewed community people using In-depth interviews (n = 16), Key-informant Interviews (n = 8), and several informal discussions to identify the most vulnerable groups within them and their social drivers of vulnerabilities. Based on the feedback received from the community, we finalized our MVGs criteria. The data collection commenced from November 2020 to March 2021. Informed consent was sought from all participants, and ethical clearance for this study was obtained from the IRB of BRAC JPGSPH. The most vulnerable groups identified in this study were: single female household heads, pregnant and lactating mothers, persons with disability, older adults, and adolescents. Our analysis also found some factors that may determine the different levels of vulnerabilities and risks faced by some groups more than others in the Rohingya and host communities during the pandemic. Some of these factors include economic constraints, gender norms, food security, social safety-security, psychosocial well-being, access to healthcare services, mobility, dependency, and a sudden halt in education. One of the most significant impacts of COVID-19 was the loss of earning sources, especially for the already economically vulnerable; this had far-reaching consequences on individuals' food security and food consumption. Across the communities, it was found that the economically most affected group was single female household heads. The elderly and pregnant and lactating mothers face challenges seeking health services due to their restricted mobility and dependency on other family members. Persons living with disabilities from both contexts reported feelings of inadequacy in their families, exacerbated during the pandemic. Additionally, the shutdown in the formal education, and informal learning centres in both communities had the most significant impact on the adolescents during the COVID-19 lockdown. This study identifies the most vulnerable groups and their vulnerabilities amid the COVID-19 pandemic in the Rohingya and Host communities of Cox's Bazar. The reasons behind their vulnerabilities are intersectional and represent deeply embedded patriarchal norms that exist in both communities. The findings are essential for the humanitarian aid agencies and policymakers for evidence-based decision-making and service provisions for addressing the vulnerabilities of the most vulnerable groups.

Abstract	The COVID-19 pandemic has raised new concerns about healthcare service availability, accessibility, and affordability in complex humanitarian settings where heterogeneous populations reside, such as Rohingya refugees in Bangladesh. This study was conducted in ten Rohingya camps and four wards of the adjacent host communities in Cox's Bazar to understand the factors influencing healthcare-seeking behavior of the most vulnerable groups (MVGs) during COVID-19 pandemic. Data were extracted from 48 in-depth interviews (24 in each community) conducted from November 2020 to March 2021 with pregnant and lactating mothers, adolescent boys and girls, persons with disabilities, elderly people, and single female-household heads. This study adopted Andersen's behavioral model of healthcare-seeking for data analysis. Findings suggest that the healthcare-seeking behavior of the participants amid COVID-19 pandemic in the humanitarian context of Cox's Bazar was influenced by several factors ranging from socioeconomic and demographic, existing gender, cultural and social norms, health beliefs, and various institutional factors. Lack of household-level support, reduced number of healthcare providers at health facilities, and movement restrictions at community level hampered the ability of many participants to seek healthcare services in both Rohingya and host communities. Most of the female participants from both communities required permission and money from their male family members to visit healthcare facilities resulting in less access to healthcare. In both communities, the fear of contracting COVID-19 from healthcare facilities disproportionately affected pregnant mothers, elderly people, and persons with disabilities accessing health services. Additionally, the economic uncertainty had a significant impact on the host communities' ability to pay for healthcare costs. These findings have the potential to influence policies and programs that can improve pandemic preparedness and health system resilience in humanitarian contexts.

Abstract	The Rohingya and Bangladeshi host communities live at a heightened risk of COVID-19 impact due to their pre-existing vulnerabilities, religious beliefs, and strict socio-cultural and gender norms that render primarily women and girls vulnerable. However, the extent of this vulnerability varies within and across population groups in the host and Rohingya communities. The intersectionality lens helps identify, recognize, and understand these factors that create inequities within populations. This study explored the factors that influenced the women and girls' access to information during the COVID-19 pandemic through an intersectional lens. This paper presents partial findings from the exploratory qualitative part of mixed-method research conducted in ten Rohingya camps and four wards of the adjacent host communities in Cox's Bazar, Bangladesh. Data were extracted from 24 in-depth interviews (12 in each community) conducted from November 2020 to March 2021 with diverse participants, including adolescent girls, younger women, adult women, pregnant and lactating mothers, persons with disabilities, older adults, and single female-household heads. All participants provided verbal informed consent before the interviews. In the case of the adolescents, assent was taken from the participants, and verbal informed consent was taken from their parents/guardians. The ethical clearance of this study was sought from the institutional review board of BRAC James P Grant School of Public Health, BRAC University. We find that the women and girls living in Rohingya communities exhibit a more profound structural interplay of factors within their socio-ecological ecosystem depending on their age, power, and position in the society, physical (dis)abilities, and pre-existing vulnerabilities stemming from their exodus, making them more vulnerable to COVID-19 impact by hindering their access to information. Unlike Rohingya, the host women and girls explain the impact of the COVID-19 pandemic on their access to information through the lens of intergenerational poverty and continuous strain on existing resources, thereby highlighting shrinking opportunities due to the influx, COVID-19 infodemic and misinformation, access to digital devices amongst the adolescents, and restricted mobility mainly due to transport, school closures, and distance-related issues. Moreover, the socio-cultural beliefs and the gender norms imposed on women and adolescent girls played an essential role in accessing information regarding the COVID-19 pandemic and consequently influenced their perception of and response to the disease and its safety protocols. Socio-cultural gender norms led to mobility restrictions, which compounded by lockdowns influenced their access to information resulting in dependency on secondary sources, usually from male members of their families, which can easily mislead/provide mis/partial information. The younger age groups had more access to primary sources of information and a broader support network. In comparison, the older age groups were more dependent on secondary sources, and their social networks were limited to their family members due to their movement difficulty because of age/aging-related physical conditions. This study explored and analyzed the intersectional factors that influenced the women and girls' access to information during the COVID-19 pandemic from two contexts with varying degrees of pre-existing vulnerability and its extent. These include gender, age, state of vulnerability, power and privilege, socio-economic status, and physical (dis)ability. It is imperative that services geared towards the most vulnerable are contextualized and consider the intersectional factors that determine the communities' access to information.

Abstract	Background: Following the mass influx of Rohingya refugees into Cox's Bazaar, Bangladesh in 2017, makeshift settlement camps in Ukhiya and Teknaf have been overburdened, leading to livelihood challenges for both Rohingya and host communities. The humanitarian crisis has had adverse effects on vulnerable populations, which include older people, persons with disabilities, adolescents, and single female household heads. Using a subset of a larger dataset on households with most vulnerable groups in both communities, we analysed the effect of the pandemic and lockdown on the livelihood of single female household (HH) heads. Methods: A cross-sectional household roster survey was designed to collect data from households with most vulnerable groups (MVGs) of host and Rohingya communities from December 2020 to March 2021; 11 host community villages and 10 Rohingya camps purposively selected as per the affiliated intervention of the project. The paper analysed quantitative and qualitative data from the sub-group of single female household heads without any income/low income. Participants were surveyed for their socio-demographic characteristics, COVID-19 experiences and knowledge, food security situation, social experiences and mental health using PHQ-2 test for depression. Results: We surveyed 432 single female HH heads. Support during the pandemic was reported to be low, with less than 50% of HHs reporting relief meeting their needs; only 36% and 15% of these HHs received rations in camps and host communities respectively. Loan facilities were mostly unavailable and there were reported insufficiencies in food consumption. Over 50% of respondents tested positive on the PHQ-2, a scale used to screen for depression. Further analyses indicates that having a chronic health issue (OR 2.2, 95% CI 1.33-3.66) was positively associated with the PHQ-2 score for Rohingya single females. For host single females, having an ill member in the HH (OR 1.46, 95% CI 1.02-2.08) and the inability to save before the pandemic (OR 1.57 95% CI 1.11-2.23) increased the odds of screening positive for depression. Conclusion: Our study findings revealed insufficiencies with economic opportunities and food security for single female-headed households, as well as a high rate of positive screening for depression amongst this population. These findings call for a more in-depth understanding of the needs of this group.
