The association between the mental health disorders, substance abuse, and tobacco use with head & neck cancer stage at diagnosis.

Mental health disorders, substance abuse, and tobacco use are prevalent in the US population. However, the association between these conditions and head and neck cancer (HNC) stage is poorly understood. This research aims to uncover the relationship between pre-existing mental health disorders, substance abuse, and tobacco use and HNC stage at diagnosis in patients receiving care in an integrated, public safety-net healthcare system. This study was a secondary data analysis of linked hospital tumor registries and electronic health record (EHR) data. The study's primary independent variables were the comorbidities of mental health disorders, substance abuse, and tobacco use. The dependent variable was HNC stage at diagnosis, operationalized as early stage (i.e., stages I, II, and III) and advanced stage (stage IV, IVA, IVB, or IVC). The analysis included multivariable logistic regression adjusted for covariates of demographic variables, tumor anato RESULTS: The study population consisted of 357 patients with median age of 59years, and was primarily male (77%), diverse (Black or African American 41%; Hispanic 22%), and from neighborhoods with low income (median average annual household income $39,785). Patients with a history of mental health disorders with or without tobacco use had significantly lower odds of advanced stage HNC at diagnosis (adjusted OR = 0.35, 95% Confidence Interval [CI]: 0.17-0.72.) while patients with a history of substance abuse with or without tobacco use had significantly higher odds of advanced stage HNC at diagnosis (adjusted OR 1.41, 95% CI: 1.01-1.98) than patients with no history of mental health disorders, substance abuse, or tobacco use. The relationship between HNC stage at diagnosis and the comorbidities of mental health disorders, substance abuse, or tobacco differs depending on the type and co-occurrence of these comorbidities. These findings demonstrate the need for innovative care delivery models and education initiatives tailored to meet the needs of patients with mental health disorders, substance abuse, and tobacco use that facilitate early detection of HNC.

Relationship between socioeconomic status and stroke: An observational and network Mendelian randomization study

BackgroundThe relationship between socioeconomic status (SES) and stroke remains controversial, and the underlying mediator is unclear. This study aimed to assess the causal relationship of SES with stroke and its subtypes and to identify potential modifiable risk factors responsible for this relationship. MethodsThe study included 372,437 participants from the UK Biobank. Over an average period of 12.13 years, 6,457 individuals (2.7 %) were recorded as having experienced a stroke. Cox proportional hazards model was used to determine the relationship between SES (average annual household income before tax and age at the end of full-time education) and stroke, ischemic stroke, and hemorrhagic stroke. Two-sample Mendelian randomization (MR) was employed to assess the causal relationship between SES and stroke and its subtypes. Furthermore, network MR was utilized to evaluate the potential mediating role of modifiable risk factors for stroke in this causal relationship. ResultsAfter adjusting for factors such as sociodemographic characteristics, health behaviors, health status, and past medical history, participants in the second highest income group showed the lowest risk of stroke, with a hazard ratio (HR) of 0.780 (95 % confidence interval [CI]: 0.702–0.866), and for ischemic stroke, the HR was 0.701 (95 % CI: 0.618–0.795). Those who completed full-time education at the latest age group(>18 years) had the lowest risk of stroke (HR: 0.906, 95 % CI: 0.830–0.988) and ischemic stroke (HR: 0.897, 95% CI: 0.811–0.992). MR analysis showed that higher income and education were both associated with a lower risk of stroke (income: inverse-variance-weighted odds ratio [ORIVW] =0.796, 95 % CI: 0.675–0.940, education: ORIVW = 0.631, 95 % CI: 0.557–0.716) and ischemic stroke (income: ORIVW = 0.813, 95 % CI: 0.684–0.966, education: ORIVW = 0.641, 95 % CI: 0.559–0.735). Additionally, hypertension had the highest mediating effect on this relationship. It accounted for 57.12 % of the effect of income on stroke, 51.24 % on ischemic stroke, and 27 % and 24 % for education. ConclusionHigher SES was associated with a lower risk of stroke and ischemic stroke, and hypertension had the highest mediating effect on this causal relationship. The results have significant public health implications, emphasizing the importance of early intervention to reduce the risk of stroke in low SES populations.

The health and economic dimensions of honey production in Imo state, Nigeria

A study was conducted on honey production in Imo state of Nigeria, with a focus on the health and economic dimensions of the industry. The research was carried out using a multi-stage sampling procedure, and a sample size of 80 honey-producer respondents was selected. Data was collected through a well-structured questionnaire and analyzed using descriptive and inferential statistics. The study found that honey producers in the area had a mean age of 51 years, 11 years of education, 21 years of farming/bee-keeping experience, and a household size of 6 persons. The average annual household income was €709.10, with a farm size/number of hives kept of 72 hives per farmer and a quantity of honey produced per annum of 145 litres. The cost and returns analysis showed that the cost of production of honey per litre and profit per litre were €0.40 and €2.40, respectively. The study also determined the nutritional uses and health benefits of honey (e.g. healing wounds, treating ulcers, controlling sore throats and colds, boosting immunity, and as an antibacterial agent). Several factors, including uncontrolled bush burning, bee forage shortage, deforestation, theft of beehives, colony absconding, and poor agricultural practices which strongly constrain honey production has been observed. It is concluded that honey production is a very profitable venture with numerous uses and health benefits and venturing youths into honey production as a source of livelihood should be encouraged, and extension education should be tailored to technologies in beekeeping and the identification of genuine honey to minimize the success of adulteration, among others.

Effects Of Rural Agriprenuership Investment On Income Generation And Poverty Reduction In Southeast, Nigeria

The study assessed the effects of rural agriprenuership investment as nexus for poverty reduction and income generation in southeast Nigeria using 200 respondents selected through random sampling technique. Data were collected using questionnaire administered in the form of interview schedule. Data collected were analyse using descriptive statistics such as frequencies percentages, and multiple regression. Results indicated that agriprenuership investors were mainly male (63%) investors with average age of 41years and were married with average household size of 6 persons. Furthermore, the agriprenuers investors’ had 10 years average experience in agriprenuership investment that earned average annual household income of N676,176.00, and were members of co-operative societies. Result also showed that the income distribution of female agriprenuerial households was at high inequality as seen in the convex nature of the Lorenz curve to the line of equality. Results also showed that the income distribution of male agriprenuers where evenly distributed as it was almost parallel to the line of equality. Result further showed agricultural enterprises accounted for 72% changes in income generation of agriprenuers as evident from the R2 of 0.72 that income from livestock production (3.390), crop production (2.710) and processing sector (1.301) were positive and significantly related to the income generation. Similarly, agricultural enterprises accounted for 84% changes in poverty reduction as production (1.674) and processing sector (3.688) were positive and significantly related to poverty reduction. From the finding, it was concluded that rural agripreneurship investment had positively and significantly influenced agriprenuers income generation and poverty reduction in Southeast, Nigeria. The study recommended for the creation of environment that favours investment in the rural areas especially in linking rural areas with microfinance

Understanding and Explaining Recent Changes in Income, Consumption and Poverty Among Agricultural Households Across Major States of India

The study, using unit level data from two nationally representative surveys, examines changes in levels and sources of household income, consumption expenditure, incidence of poverty and determinants of household income and poverty among agricultural households. The study shows that across most of the states, there has been a significant decrease in the per cent share of income from cultivation coupled with an equally significant increase in the share of income from wages and salary; average annual household income of such households is higher than their average annual consumption expenditure and there has been a significant decrease in the incidence of poverty among them. The results of regression analysis show that household size, head of the household being male, literacy, farm size, income from cultivation, awareness of minimum support price (MSP), access to technical training, engagement in non-farm business and engagement in wages and salary have significant positive effect on households income and lower the probability of a household being poor across major states.

"Black Women Should Not Die Giving Life": The lived experiences of Black women diagnosed with severe maternal morbidity in the United States.

We sought to understand the lived experiences of Black women diagnosed with severe maternal morbidity (SMM) in communities with high maternal mortality to inform practices that reduce obstetric racism and improve patient outcomes. From August 2022 through December 2022, we conducted a phenomenological, qualitative study among Black women who experienced SMM. Participants were recruited via social media and met inclusion criteria if they self-identified as Black cisgender women, were 18-40 years old, had SMM diagnosed, and lived within zip codes in the United States that have the top-five highest maternal mortality rates. Family members participated on behalf of women who were deceased but otherwise met all other criteria. We conducted in-depth interviews (IDIs), and transcripts were analyzed using inductive and deductive methods to explore birth story experiences. Overall, 12 participants completed IDIs; 10 were women who experienced SMM and 2 were mothers of women who died due to SMM. The mean age for women who experienced SMM was 31 years (range 26-36 years) at the time of the IDI or death. Most participants had graduate-level education, and the average annual household income was 123,750 USD. Women were especially interested in study participation because of their high-income status as they did not fit the stereotypical profile of Black women who experience racial discrimination. The average time since SMM diagnosis was 2 years. Participants highlighted concrete examples of communication failures, stereotyping by providers, differential treatment, and medical errors which patients experienced as manifestations of racism. Medical personnel dismissing and ignoring concerns during emergent situations, even when raised through strong self-advocacy, was a key factor in racism experienced during childbirth. Future interventions to reduce racism and improve maternal health outcomes should center on the experiences of Black women and focus on improving patient-provider communication, as well as the quality and effectiveness of responses during emergent situations. Précis statement: This study underscores the need to center Black women's experiences, enhance patient-provider communication, and address emergent concerns to mitigate obstetric racism and enhance maternal health outcomes.

Mediating Effect of Tobacco Dependence on the Association Between Maternal Smoking During Pregnancy and Chronic Obstructive Pulmonary Disease: Case-Control Study.

Maternal smoking during pregnancy (MSDP) is a known risk factor for offspring developing chronic obstructive pulmonary disease (COPD), but the underlying mechanism remains unclear. This study aimed to explore whether the increased COPD risk associated with MSDP could be attributed to tobacco dependence (TD). This case-control study used data from the nationwide cross-sectional China Pulmonary Health study, with controls matched for age, sex, and smoking status. TD was defined as smoking within 30 minutes of waking, and the severity of TD was assessed using the Fagerstrom Test for Nicotine Dependence. COPD was diagnosed when the ratio of forced expiratory volume in 1 second to forced vital capacity was <0.7 in a postbronchodilator pulmonary function test according to the 2017 Global Initiative for Chronic Obstructive Lung Disease criteria. Logistic regression was used to examine the correlation between MSDP and COPD, adjusting for age, sex, BMI, educational attainment, place of residence, ethnic background, occupation, childhood passive smoking, residential fine particulate matter, history of childhood pneumonia or bronchitis, average annual household income, and medical history (coronary heart disease, hypertension, and diabetes). Mediation analysis examined TD as a potential mediator in the link between MSDP and COPD risk. The significance of the indirect effect was assessed through 1000 iterations of the "bootstrap" method. The study included 5943 participants (2991 with COPD and 2952 controls). Mothers of the COPD group had higher pregnancy smoking rates (COPD: n=305, 10.20%; controls: n=211, 7.10%; P<.001). TD was more prevalent in the COPD group (COPD: n=582, 40.40%; controls: n=478, 33.90%; P<.001). After adjusting for covariates, MSDP had a significant effect on COPD (β=.097; P<.001). There was an association between MSDP and TD (β=.074; P<.001) as well as between TD and COPD (β=.048; P=.007). Mediation analysis of TD in the MSDP-COPD association showed significant direct and indirect effects (direct: β=.094; P<.001 and indirect: β=.004; P=.03). The indirect effect remains present in the smoking population (direct: β=.120; P<.001 and indirect: β=.002; P=.03). This study highlighted the potential association between MSDP and the risk of COPD in offspring, revealing the mediating role of TD in this association. These findings contribute to a deeper understanding of the impact of prenatal tobacco exposure on lung health, laying the groundwork for the development of relevant prevention and treatment strategies.

Empirical analysis of health-related behaviors among older Hakka adults: a latent class analysis.

Little is known about health-related behaviors of the older Hakka population in China. We aimed to explore the characteristics and correlates of health-related behaviors among older Hakka adults. We used data from the China's Health-Related Quality of Life Survey for Older Adults 2018. Latent class analysis (LCA) defined latent classes of health-related behaviors for 1,262 older Hakka adults aged 60 and above. Generalized linear regression and multinomial logistic regression analysis were used to identify factors influencing the number and the latent classes of health-related behaviors, respectively. The LCA showed that the latent classes could be stratified as the risk group (14.82%), healthy group (55.71%), and inactive group (29.48%). Sex, age, years of education, current residence, living arrangement, average annual household income, and currently employed were associated with the number of healthy behaviors. Compared with the participants in the healthy group, widowed/others (OR = 5.85, 95% CI = 3.27, 10.48), had 15,001-30,000 (OR = 2.05, 95% CI = 1.21, 3.47) and 60,001 or higher (OR = 3.78, 95% CI = 1.26, 11.36) average annual household income, and currently employed (OR = 3.40, 95% CI = 1.99, 5.81) were highly associated with risk group. Additionally, the participants who are widowed/others (OR = 4.30, 95% CI = 2.70, 6.85) and currently employed (OR = 1.95, 95% CI = 1.27, 2.98) were highly associated with the inactive group. This study identified factors specifically associated with older Hakka adults' health-related behaviors from an LCA perspective. The findings indicate that policymakers should give more attention to older adults living alone and implement practical interventions to promote health-related behaviors among them.

Treatment access and satisfaction on disease-modifying therapies of neuromyelitis optica spectrum disorder patients in China: a cross-sectional survey.

Neuromyelitis optica spectrum disorder (NMOSD) is a rare and debilitating disease that has become more widely recognized in China. Legislative measures have been implemented by the government to improve treatment access for rare diseases. To investigate the diagnostic journey, treatment status, treatment accessibility, and treatment satisfaction of the NMOSD patients on disease-modifying therapies (DMTs) in China. A patient online survey. This cross-sectional online survey was conducted between November 2022 and January 2023. Patients over 18 years old and diagnosed with NMOSD were included. The questionnaire consisted of five sections covering demographics, diagnostic and treatment experiences, DMTs availability, cost and affordability, and treatment satisfaction using the Treatment Satisfaction Questionnaire for Medication (version II). Patient opinions and demands were also collected at the end of the survey. A total of 375 patients diagnosed with NMOSD were recruited, of which 321 patients used DMTs. It required 1.22 ± 3.22 years and 3.58 ± 4.24 hospital visits for a definitive diagnosis. One-third of the patients still needed to travel for over 2 h to access DMTs. The total treatment expenditure was estimated to be CNY 59,827.00 (USD 8315.95) a year. Drug expenses alone accounted for 52.22% of the average annual household income. The most common challenges perceived were the inability to afford treatment and a lack of effective options. No significant difference was found in treatment satisfaction among DMTs, except that rituximab scored lowest in convenience compared to other DMTs. Patients' age and travel time required to obtain medications were negatively associated with global treatment satisfaction. In China, patients with NMOSD face challenges in obtaining proper treatment due to diagnostic difficulties, distant medication access, and high costs. Policies should prioritize improving disease education and alleviating financial burdens for the patients.

Income inequalities in exposure to endocrine disrupting chemicals among pregnant women in Taiwan

BackgroundExposure to endocrine disrupting chemicals (EDCs) is being rigorously studied in associations with various health outcomes, however less attention has been paid to its socio-economic determinants. This study investigated how EDCs exposure levels in pregnant women could differ on individual- and area- level income in Taiwan. MethodsUrinary measurements of phthalates, nonylphenol, bisphenol A, parabens and individual socio-economic variables (income, education, etc.) of pregnant women from Taiwan Maternal and Infant Cohort Study (TMICS) were linked via residence to area-level average annual household income. EDCs concentrations were compared between the four main Taiwan regions (North, Central, South and East) and between individual income groups. Lorenz curves were plotted to describe inequalities in EDCs exposure, and EDCs exposure related to income. Concentration indexes (CIx) were calculated and compared between the four regions. ResultsNo significant differences between EDCs concentrations adjusted for molar mass and creatinine across individual-level income groups were detected. Exposure inequalities were highest for parabens (CIx = 73.6 %), BPA (CIx = 73.6) and low molecular weight (LMW) phthalates (CIx = 63.3 %). Lorenz curve for LMW phthalates distribution across area-level income was significantly above the equality line (CIx = -21.9 %, p-value < 0.05). Stratification showed significant differences in inequality (p = 0.046) in LMW phthalates exposure across area-level income between South (CIx = -23.1 %), East (CIx = -35.3 %), North (CIx = -3.3 %) and Central (CIx = -6.5 %) regions. ConclusionInequalities in LMW phthalates exposure related to area-level income in East and South regions suggest target areas for public health interventions in terms of environmental regulations and health promotion. Using Lorenz curves and CIx to describe inequalities can be useful in case of inadequate sample sizes in costly human biomonitoring studies, however this method needs to be further developed and validated using human biomonitoring datasets in more diverse populations with larger socio-economic inequalities.

Forest products monetary contribution to households’ income: A means to improve the livelihood of a low-income rural community in South Ethiopia

Forest products and forest-based activities in Ethiopia play a substantial economic contribution to the livelihoods of rural households. Despite its pivotal role, empirical data are inadequate on forests' monetary contribution across a range of ecological locations and social situation, particularly for rural agrarian communities of the developing nations, like Ethiopia. We estimated the economic contributions of forest products and forest-based activities to forest-dependent rural households’ income and highlighted key socioeconomic characteristics in Wolaita, Ethiopia. We collected demographic, socioeconomic, and forest use data using a semi-structured questionnaire survey of 384 households, and surveyed markets to determine the prices of forest products for the valuation of forest use in three districts. We used descriptive statistics, the Chi-square test, the two-sample t-test, and one-way ANOVA to analyze the data. Findings showed that all respondents were engaged in one way or another in forest-based activities, while 84.6 % were involved in farming. The annual average income from forest products was 252.7US per household, contributing to 28.1 % of the total yearly average income (989.4US$), and 38.3 % relative forest income (RFI). Annual mean household income from crops was 648.1US$. Average annual household income from grazing, charcoal, firewood, woodcutting, cut-and-carry, NTFP, seed selling, medicinal plants, and seedling selling was 77.3 %, 58.4 %, 50.2 %, 24.1 %, 18.5 %, 12.7 %, 7.1 %, 6.8 % and 5.4 % of the total annual mean income, respectively revealing a significant difference (p < 0.05). Family size, farmland size, distance to the forest, and occupation were the determinants of the contribution of forest products to household income. In general, poor households derive the highest relative forest income implying high dependence of the poorer on forest resources in the study area. The findings provide useful information for developing sustainable forest management policies and strategies to enhance the economic and ecological benefits of forests, and highlight the need for funding projects to pay attention to the specific household variables that affect forest use. Mainstreaming conservation activities in development sectors and integrating development and conservation projects may improve the livelihood of the low-income family in the region.

Is the internet penetration pro-poor? Evidence from a panel data analysis

The impacts of internet use on income and poverty status are contentious despite extensive research efforts. This paper re-examines these influences using five-wave panel data extracted from the Vietnam Access to Resources Household Survey (VARHS). A two-step system called Generalized Methods of Moments (GMM) and Propensity Score Matching (PSM) is the primary metric for estimating internet-income and internet-poverty correlations. The analysis revealed that internet use assisted rural households, including the poor ones, in fostering their livelihoods in the 2008–2016 period: (1) internet access increased the average annual household income per capita by 4.5 million Vietnamese dongs, accounting for at least 17% of the overall income; (2) it decreased the probability of being poor by around 4%. This study suggests that the universalisation of the internet, along with improvements in digital literacy and digital applications provided for rural dwellers, particularly the needy, should be essential for poverty reduction programmes in the context of developing countries.

Gum and Resin Production and Marketing: Implications for Pastoral Livelihood in Adadle District, Somali Region, Ethiopia

Both locally and nationally, Ethiopia’s gum resin sector has a substantial economic impact. Even though collecting and selling gum and resin is one of the main livelihood activities in Ethiopia’s remote pastoral areas, there are few case studies that adequately reflect national realities. Therefore, the goal of this study is to pinpoint and evaluate gum and resin production and sale, as well as any implications for pastoral livelihood, in the Adadle district of the Somali Region. Both purposive and random sampling techniques were employed. The primary data gathering technique used were household surveys, key informant interviews, focus groups, market surveys, direct observation, and surveys of community-based organizations. Multiple response tests, one-way ANOVA, and descriptive statistics were used in SPSS Version 26 to statistically analyze the collected data. The study discovered many Acacia, Boswellia, and Commiphora tree species that are employed in the production of gum and resin. It was also found that natural oozing and artificial tapping were the methods used for collecting and harvesting gum and resin. The average amount of gum and resin/frankincense harvested annually by each family was 219.82 kg and 58.27 kg, respectively, with gum harvesting being substantially higher ( p 0.05 ) than resin harvesting. The recurrent drought, season, and awareness level of harvesters on taping were the factors affecting the quantity and quality of production. The average annual household income from gum and resin/frankincense was 18,684 Ethiopian Birr and 43,704 Ethiopian Birr, respectively. The mean annual income from resin was substantially larger ( p 0.05 ) than that of gum. The gum and resin market chain in the area comprises eight actors with five market channels. The research also demonstrates that the income made by selling gum and resin was used to pay for basic necessities for the family, save money for health care and medications, and pay for social concerns and educational expenses. Recurrent drought, lack of market access and market expertise, lack of institutional cooperatives, and lack of infrastructure and facilities were all determined to be obstacles to the production and sale of gum and resin. Generally, resources should be conserved and interventions should be done to ensure the sustainability of the resource base and improve production potential. Proper tapping techniques should be introduced to enhance production potential, and access to market information should be ensured to maximize primary producers’ income share insured for maximizing the income share of primary producers.

Impact of participation in community-based sheep breeding practice on the income of household: A case of Adiyo Woreda, Kaffa Zone, SNNPRS, Ethiopia

Community-based sheep breeding practice emerged in 2009 G.C as a possible option to understand the selection practices of the traditional breeders and to create genetic gains that improve sheep productivity and provides an important source of income for the household. This study was conducted in Adiyo woreda, to assess the impact of participation in community-based sheep breeding practice on the income of a household in southern Ethiopia. Adiyo was selected purposively, and simple random sampling techniques were employed to obtain the desired sample. Data were collected through a cross-sectional survey from a sample of 368 respondents, 165 of whom had participants and 203 non-participants. Primary data were collected through focused group discussion, key informant interviews, and questionnaires. Secondary data were collected from a review of related literature. Descriptive statistics and econometric models are used for analyzing quantitative data. A propensity score matching procedure was employed to decide the causal relationship between participant and non-participant households. The result of propensity score matching method analysis shows that participation in community-based breeding practice has increased average annual household income by 4,301.31birr for the participant than non-participants households and the value is significant at 1% level. The sensitivity analysis result showed that impact results estimated by this study were confident to unobserved selection bias. Hence, the community-based breeding practice has a positive and significant impact on the annual income of households. Hence improving the productivity of local sheep by organizing farmers in CBBP can significantly increase the income of smallholder farmers. Therefore, governmental and non-governmental should work on improving the productivity Bonga sheep breed performance.

An Empirical Study on Physical Subhealth Risk Perception: A Physical Examination Data of Tertiary Grade-A Hospitals in Anhui Province, China.

Physical subhealth directly correlates to people's work effectiveness and quality of life, so subhealth prevention has become an urgent medical problem. A random sampling method was used to conduct a questionnaire survey of physical examinees from June to September, 2019. In total, 770 people participated in our study. The Pearson correlation and multiple stepwise regression analysis were used to explore the relationship among demographic variables, physical subhealth, and risk perception. Also, this study used a two-way interaction moderated multiple regression approach to examine the moderating effects of demographic variables on physical subhealth and risk perception. The risk perception level was negatively associated with physical health. Age, education level, and subhealth proportion in the work unit all significantly and positively influence physical health, whereas living place, subhealth duration, and marital status negatively influence physical health. Living place, average annual household income, number of employees in the work unit, and subhealth proportion in the work unit significantly and positively influence the risk perception, and only age negatively influences the risk perception. The number of children had a moderating effect on physical subhealth and risk perception (Interaction coefficient α = -0.3, P < 0.05). To achieve the overall improvement of public health, relevant management departments can provide targeted interventions for the public with different levels of risk perception. Also, the physical subhealth of the public can be addressed by encouraging the public to attach importance to education, improving the public living environment to build a livable city, strengthening psychological guidance and intervention for couples heading toward divorce to reduce the divorce rate, focusing on the health of work unit employees and regularly organizing employees to attend medical checkups, and actively responding to the national policy of family planning.

What is the relationship between ecosystem services and farmers’ livelihoods? Based on measuring the contribution of ecosystem services to farmers’ livelihoods

The relationships between ecosystem services and farmers’ livelihoods are important for ecological and livelihood sustainability. In this paper, Chongqing was picked up as a case to elucidate the contribution of ecosystem services to farmers’ livelihoods. First, we constructed a DPSIR (driver, pressure, state, impact and response) framework of ecosystem services and farmers’ livelihoods through participatory farmers’ livelihoods surveys and empirical data from the literature. Then, a 48-node Bayesian network model were used to explore the explicit and implicit impacts of both ecosystem services and farmers’ livelihoods, and to determine the key factors. Finally, we analyzed the contribution of ecosystem services to different types of farmers’ livelihoods. The results showed that ecosystem services have a significant impact on the farmers’ livelihoods. The probabilities of high state for ecosystem services and livelihood outcomes were 17.6% and 30.7%, respectively. While the probabilities of medium state were 51.2% and 45.4%, respectively. Particularly for low-income farmers, the impact on them increased with the increasing of ecosystem services (such as esthetic landscapes and food production). For different types of farming households, the most important contributor of ecosystem services-related income were pure farming households, part-time farming households and nonfarming households, accounting for 77.3%, 36.3%, and 14.8% of the total average annual household income, respectively. Our findings suggested that in promoting sustainable management of ecosystems, the contribution of ecosystem services to farmers’ livelihoods and their impact on farm income and the ecosystem services value should be considered.

Community Climate Vulnerability Assessment (CCVA) to Climate Change of a Hilly Area of Rangamati District in Bangladesh

The global challenge of Climate change poses a significant threat to humanity, with its impacts already being felt in various parts of the world through unpredictable and severe weather events leading to property damage and loss of life (IPCC, 2014). Community resilience is vital in reducing the losses caused by climate change, and it depends on an understanding of perceived risks, vulnerabilities, and local efforts to mitigate them. The Chittagong Hill Tracts of Bangladesh is one of the regions that is particularly vulnerable to climate change, due to its geography, degradation of forests, sensitivity of livelihoods, and low capacity in comparison to other parts of the country (World bank 2018).Although vulnerability assessments to climate change have been conducted previously, there remains a gap in involving indigenous communities residing in hilly areas of Bangladesh. The recognition of climate change risks as perceived by local communities could serve as a foundation for developing locally-led adaptation plans aimed at building local resilience.The Basonto Mon watershed is located in Rangamati district of Bangladesh, with GPS coordinates of 22˚ 40.218"N 92˚ 16.620" E (GPS coordinates derived from Google Earth) and an elevation of 390 feet above sea level. The area comprises of five villages from varying elevations and is primarily inhabited by the Chakma community. There are 269 households in the region, primarily relying on Jhum cultivation, agriculture on fringe lands, and seasonal labor for their livelihoods, with an average annual household income of BDT 96000 (approximately US$ 1132). About 76% of the community consider themselves under serious threat from the effects of climate change, while 24% have limited understanding of the issue. Approximately 20% of the respondents believe that their livelihoods will be mostly affected by climate change, while 78% identified multiple impacts including health, disaster intensity, family workload, and more. The region is also facing severe soil erosion caused by deforestation, incorrect agricultural practices, and the monoculture of forest species such as teak. The community is at risk from agricultural drought, flash floods, landslides, cyclones, among other things, with the most impacted months being March to August.Climate drivers in the area include erratic rainfall, sudden heavy downpours, increased number of rainless days, and rising temperatures. Acute water scarcity caused by the drying of streams is another major concern for the community and has a widespread impact on women and their families. The most vulnerable sectors identified are the forest and ecosystem, livelihoods, and water security.Approximately 75% of the population is literate and has access to educational institutions and health clinics. However, the environment is fragile. To address this, there are three main priorities: 1) preserving the forests through cooperative efforts, reforestation, and public education, 2) promoting sustainable and climate-resistant agriculture, as well as alternative livelihoods and market access, and 3) improving access to clean water and preserving water sources through community-led management. Key stakeholders, such as the CHT institutions and local government bodies, are crucial in supporting the community in becoming more resilient to the effects of climate change.

Evaluation of the nonmarket value of livestock and poultry feces returning to farmland utilization using CVM in Heilongjiang, China

Aiming at a series of hot issues and topics, such as resource waste, environmental pollution, and Mollisol protection, related to the arbitrary discharge of livestock and poultry feces, livestock and poultry feces are taken as the research object, a questionnaire survey was conducted to investigate residents' cognition and willingness to pay (WTP) for the nonmarket value of livestock and poultry feces returning to farmland in Heilongjiang Province, China. The contingent valuation method (CVM) was used for the correlation analysis of WTP and socioeconomic characteristics, and correlation analysis of payment mode and socioeconomic characteristics. Meanwhile, the factors influencing WTP and payment mode were analyzed. The results show that the majority of the respondents are aware of the harmfulness of the arbitrary discharge of livestock and poultry feces and the importance of its nonmarket regeneration value. Approximately 90.09% of respondents were willing to pay for the return of livestock and poultry feces to fields. In 2020, the total value of WTP of livestock and poultry feces returning to farmland in Heilongjiang Province was 4.65 billion CNY, equivalent to 1.32% of the total agricultural production of Heilongjiang Province in the same year. And the nonmarket value of livestock and poultry feces is estimated to be 1456.69 CNY/t. The annual average WTP of rural and urban households is 286.42 CNY and 422.90 CNY per household, accounting for 0.46% and 0.52% of the average annual income of households, respectively. Therefore, the return of livestock and poultry feces to farmland utilization has a high nonmarket value. The analysis shows that the average annual household income is a significant factor in WTP, and the registered permanent residence type and the average annual household income are significant factors in payment mode. The research results should provide a scientific and theoretical basis for the government's policy and decision-making on the return of livestock and poultry feces to farmland.

TIME-SERIES ANALYSIS OF FEMALE EMPLOYMENT IN JAPAN

In Japan, the declining birthrate and an aging population have made the labor supply by women very important. Numerous studies have analyzed the choice of women in having children or continuing to work. These studies provide very important insights into the employment choices of Japanese females. However, they mainly use micro data and focus only on specific time points. In this study, we investigate the effects of the average income, tax rate, and rate of advancement to university on employment behavior among Japanese women using time-series data. The results of multiple regression analyses suggest that male regular employment rate, average annual household income, female university advancement rate, and consumption tax rate have different effects on regular and non-regular employment rates of Japanese women. The male regular employment rate has positive effects on female regular employment rate, but it has no effect on female non-regular employment rate. The high household income seems to reduce the probability of women working as non-regular workers but does not seem to reduce the probability of them working as regular workers. The consumption tax rate has effects only on female non-regular employment rate. A high consumption tax rate promotes the female labor supply as non-regular workers.
