Sociocultural factors and perceptions associated with voluntary and permanent relocation of flood victims: A case study of Sekondi-Takoradi Metropolis in Ghana

Flooding is a major problem in many developing urban centres in Ghana, including the Sekondi-Takoradi Metropolis (STM). Residents who are living close to the Anankwari, Kansawura and Whin rivers in the metropolis often experience flooding when the rivers overflow their banks, resulting in lives being lost, people being displaced and properties being destroyed. One durable solution to the flooding problem is voluntary and permanent relocation of ‘vulnerable’ residents; but this form of solution cannot be achieved without a clear understanding of the sociocultural factors that influence the decision-making process. This study uniquely investigated the sociocultural and economic factors affecting voluntary and permanent relocation of flood victims, using Eshiem, Kansawurodo and Whindo communities as a case study. Employing a mixed cross-sectional design method, 207 heads of households were selected to fill in questionnaires; interviews were conducted with nine representatives of the traditional councils, and areas affected by flooding were photographed. The findings show that voluntary and permanent relocation was overlooked by most flood victims due to perceived inability to rent new places owing to low incomes, fear of losing income-generating ventures that serve as sources of livelihoods, hope of gaining income from the oil production within the region and the need for restitution from government before evacuation. From a sociocultural viewpoint, they felt uncomfortable with losing ancestral lands and landed properties as well as breaking long-standing ties with their community folks and other networks. Flood victims’ willingness to stay in the flood-prone communities was also influenced by duration of stay in the communities and ownership of landed assets. When considering voluntary and permanent relocation of flood victims as a durable solution in the future, these sociocultural and economic factors need to be carefully considered.http://dx.doi.org/10.4102/jamba.v9i1.30

Investigation of yeast genes possibly involved in mtDNA stability using the nematode Caenorhabditis elegans

Screening of Caenorhabditis elegans genes possibly involved in the mitochondrial genome maintenance was performed using our previous validated method of RNAi combined with ethidium bromide. This was to knock down C. elegans genes homologous to yeast genes known to be involved in mtDNA stability but of unknown molecular function or to identify transient components that could play important role on the stability of mtDNA in a temporal and/or spatial manner. C. elegans homologs for 11 genes among 27 yeast genes for which deletion leads to a rho0 state were found, however, only 5 genes were present in the RNAi library. Out of these 5 genes, 1 gene (homolog of GEM1) gave a clear L3 arrest on RNAi and ethidium bromide indicating its involvement on mtDNA stability. Four other genes homologs of MTG2, YER087W, AVL9 and RRG3 did not lead to L3 arrest even though their deletion in Saccharomyces cerevisiae leads to rho0 state. Although MTG2 has been reported to be important in the function and structure on mtDNA stability in yeast, our results did not support those findings in C. elegans. The human homolog of this gene (MIRO1) can be considered as a candidate gene involved in mtDNA stability and sequenced in patients with mtDNA depletion diseases.Keywords: mtDNA, Caenorhabditis elegans, nucleoid, RNAi, candidate genes, homolog, MIRO

Restoration of degraded forest reserves in Ghana

Deforestation in Ghana has led to a forest loss of almost 20% from 9,924,000 ha in 1990 to 7,986,000 ha today. To restore degraded lands, Forest Landscape Restoration has become a critical approach globally. This study was conducted in Ghana focusing on the examples of two forest landscape restoration projects in the Pamu Berekum Forest Reserve: 10-year-old mixed-stands of two to four native tree species and an exotic species stands, including Triplochiton scleroxylon, Terminalia ivorensis, Ceiba pentandra, Nauclea diderrichii and Cedrela odorata at Pamu Berekum 1 and 4-year-old Tectona grandis and 2-year-old Gmelina arborea monoculture stands at Pamu Berekum 2. Estimates of productivity in the restored forests are described, as well as the effects of the restoration on provision of ecosystem service and benefits obtained by local communities. Stand productivity was assessed as mean annual increment of diameter and height, biomass production, and standing volume. For ecosystem services, carbon stocks were calculated for the restored forests; other ecological benefits, as well as financial benefits, were obtained through interviews with fringe communities. The results indicate that FLR can be implemented successfully using different models provided that local communities are involved during the planning and implementation of interventions. When all stands were projected to 10 years, results show higher productivity in T. grandis (331.77 m3 ha-1) and G. arborea stands (1,785.99 m3ha-1) compared to mixed stand (160.41 m3 ha-1). The Gmelina arborea stand was more productive and had higher carbon stocks (1,350.10 Mg ha-1) relative to the T. grandis stand (159.89 Mg ha-1). Both restoration projects were found to deliver important benefits and ecosystem services at the local and national levels, including direct and indirect benefits. The results provide an example for forest/environmental managers on how FLR might be implemented to create multiple benefits at different levels from local communities to the national level. Thus, these results may be useful for guiding successful restoration activities within the context of the ongoing global Forest Landscape Restoration efforts

Moderating Effects of Socio-Demographic Factors in Associations Between Acculturation and Dietary and Physical Activity Behaviours: a Study of Australian Residents Born in Sub-Saharan Africa

Several studies have demonstrated that acculturation shapes post-migration dietary and physical activity behaviours, but the additional effect of socio-demographic factors in this relationship is under-researched. This study examined the moderating effects of socio-demographic factors in the relationship between acculturation and dietary and physical activity behaviours. Using quota sampling and self-selection methods, 253 Australian residents born in Sub-Saharan Africa (SSA) were recruited for a survey. Dietary behaviour was measured by fat intake and fruits/vegetables/fibre intake. Physical activity was assessed by activities at work, travel, and recreation. Socio-demographic factors in this study comprised gender, age, duration of residence in Australia, place of residence before immigration, Australian state of residence, employment status, and income levels. Acculturation was measured by maintenance of heritage culture (cultural maintenance) and participation in host country culture (cultural participation). The findings indicate that none of the socio-demographic variables had significant effects on the relationship between acculturation and fat intake. In contrast, fruits/vegetables/fibre intake was significantly associated with cultural maintenance, but the association differed significantly by age groups. A significant relationship was also found between fruits/vegetables/fibre intake and cultural participation among those with shorter duration of residence (< 10 years) in Australia as well as those who resided in urban areas before immigration. Physical activity was significantly associated with cultural maintenance among younger participants (aged < 37 years). Overall, the findings demonstrate that associations between post-migration dietary and physical activity behaviours and acculturation are partly moderated by age, duration of residence, place of residence before immigration, and employment status. While recognising that these associations need to be explored further using a bigger sample size, the findings provide important first evidence on the interplay between acculturation and socio-demographic factors in understanding health behaviours in this population

Demographic and socio-economic factors affecting bed net ownership, usage, and malaria transmission among adult patients seeking healthcare in two Ghanaian urban cities

BACKGROUND: The most cost-effective malaria prevention and control strategy is the use of a bed net. However, several factors affect the ownership and usage of bed nets among the adult population. Hence, this study aimed to examine socio-demographic factors affecting bed net ownership, usage and malaria transmission among adult patients seeking healthcare in two Ghanaian urban cities.METHODS: This hospital-based cross-sectional study was conducted, between January and September 2021, at Bremang Seventh-Day Adventist Hospital, Suame Municipal, Ashanti Region and Sunyani Municipal Hospital, Sunyani, Bono Region, Ghana. Structured questionnaires were administered to a total of 550 participants to ascertain their ownership and usage of the bed nets. Afterwards, finger prick blood samples were collected for malaria microscopy. Crude and adjusted prevalence ratios (PR) and their respective 95% CIs were calculated, using Poisson regression with robust standard errors, to show associated variables in bivariate and multivariate analyses respectively. R software (version 4.1.1) was used to perform all statistical analyses.RESULTS: About 53.3% (n = 293) of participants owned at least one-bed net but only 21.5% (n = 118) slept under it the previous night. Those married were 2.0 (95% CI: 1.6 - 2.5) and 2.4 (95% CI: 1.6 - 3.5) times more likely to own and use a bed net respectively than those who never married. Also, pregnant women were 1.3 (95% CI: 1.1 - 1.6) and 1.8 (95% CI: 1.3 - 2.5) times more likely to own and use a bed net respectively than non-pregnant. Even though income levels were not associated with bed net ownership and usage, students were 0.4 (95% CI: 0.2 - 0.6) and 0.2 (95% CI: 0.1 - 0.5) times less likely to own and use bed net respectively compared to formally employed persons. The overall malaria prevalence rate was 7.8%. Malaria-negative patients were 1.6 (95% CI: 1.2 - 2.0) and 2.4 (95% CI: 1.4 - 4.1) times more likely to own and use bed nets respectively than malaria positive. Patients with tertiary education recorded the lowest malaria prevalence (3.5%, n = 4). None of those with a monthly income &gt; $300 recorded a case of malaria. On the contrary, majority 83$150.CONCLUSION: The National Malaria Control Program should conduct comprehensive mapping of all urban population segments before launching mass bed net distribution campaigns, taking into account demographic and socioeconomic factors to enhance bed net utilization and reduce malaria prevalence.</p

Job Satisfaction and Its Associated Factors Among Optometrists in Ghana: a cross-sectional study

Job satisfaction describes an employee’s motivation and/or feeling of satisfaction towards his/her work. Globally, healthcare professionals’ turnover and retention play a critical role in the delivery of essential health services. In Ghana, however, little has been done to ascertain job satisfaction levels among human resources for eyehealth. The objective of this study therefore was to assess job satisfaction and its associated factors among optom‑ etrists in Ghana

A Review of the Suitability of Using Eco-Efficiency Principles in Managing Environmental Impacts of the Packaged Water Industry in Ghana

The production and use of sachet water in Ghana has been consistently increasing, filling the gap of inadequate access to safe drinking water. Despite the obvious significant socio-economic impact of the packaged water industry in Ghana, the associated environmental impacts of the production and use cannot be overlooked. The aim of this paper is to analyze the prospects of eco-efficiency approach as a more sustainable means of production in the industry, leading towards the sustainable development agenda of the country. The methodology employed in this paper is desktop research with qualitative data collection and analysis, utilizing existing literature or secondary data. It was concluded that there are many good reasons for adopting an eco-efficiency in the packaged water industry, including reducing operating costs and improve profitability by reducing energy, water supply, and solid waste costs, reducing water wastage and contribute in developing solid waste minimization plans. The significance of this paper is to increase the awareness of the effect of improper disposal of sachet waste on the Ghanaian environment and also seeks to inform the management of the many companies in the packaged water industry, stakeholders and consumers to be environmentally responsible, as their actions can help protect and improve the natural environment while improving the overall economy.O

Tropical root responses to global changes:A synthesis

Tropical ecosystems face escalating global change. These shifts can disrupt tropical forests' carbon (C) balance and impact root dynamics. Since roots perform essential functions such as resource acquisition and tissue protection, root responses can inform about the strategies and vulnerabilities of ecosystems facing present and future global changes. However, root trait dynamics are poorly understood, especially in tropical ecosystems. We analyzed existing research on tropical root responses to key global change drivers: warming, drought, flooding, cyclones, nitrogen (N) deposition, elevated (e) CO2, and fires. Based on tree species‐ and community‐level literature, we obtained 266 root trait observations from 93 studies across 24 tropical countries. We found differences in the proportion of root responsiveness to global change among different global change drivers but not among root categories. In particular, we observed that tropical root systems responded to warming and eCO2 by increasing root biomass in species‐scale studies. Drought increased the root: shoot ratio with no change in root biomass, indicating a decline in aboveground biomass. Despite N deposition being the most studied global change driver, it had some of the most variable effects on root characteristics, with few predictable responses. Episodic disturbances such as cyclones, fires, and flooding consistently resulted in a change in root trait expressions, with cyclones and fires increasing root production, potentially due to shifts in plant community and nutrient inputs, while flooding changed plant regulatory metabolisms due to low oxygen conditions. The data available to date clearly show that tropical forest root characteristics and dynamics are responding to global change, although in ways that are not always predictable. This synthesis indicates the need for replicated studies across root characteristics at species and community scales under different global change factors

Toward a Coordinated Understanding of Hydro-Biogeochemical Root Functions in Tropical Forests for Application in Vegetation Models

Tropical forest root characteristics and resource acquisition strategies are underrepresented in vegetation and global models, hampering the prediction of forest–climate feedbacks for these carbon-rich ecosystems. Lowland tropical forests often have globally unique combinations of high taxonomic and functional biodiversity, rainfall seasonality, and strongly weathered infertile soils, giving rise to distinct patterns in root traits and functions compared with higher latitude ecosystems. We provide a roadmap for integrating recent advances in our understanding of tropical forest belowground function into vegetation models, focusing on water and nutrient acquisition. We offer comparisons of recent advances in empirical and model understanding of root characteristics that represent important functional processes in tropical forests. We focus on: (1) fine-root strategies for soil resource exploration, (2) coupling and trade-offs in fine-root water vs nutrient acquisition, and (3) aboveground–belowground linkages in plant resource acquisition and use. We suggest avenues for representing these extremely diverse plant communities in computationally manageable and ecologically meaningful groups in models for linked aboveground–belowground hydro-nutrient functions. Tropical forests are undergoing warming, shifting rainfall regimes, and exacerbation of soil nutrient scarcity caused by elevated atmospheric CO2. The accurate model representation of tropical forest functions is crucial for understanding the interactions of this biome with the climate

Climate-smart cropping systems for resilient food production in Sub-Saharan Africa in the face of changing climate: a review

As the global population is projected to reach 9.6 billion by 2050, the urgency for effective water management strategies that can support both ecosystems and food production is paramount. This article utilizes a systematic review to underscore the importance of water-efficient cropping systems in aiding small-scale farmers in navigating the intricate challenges of climate change. Sub-Saharan Africa is especially susceptible to climate change, with forecasts predicting a significant rise in average daily temperatures (1.5−2.5 °C) and increasingly unpredictable rainfall patterns by the end of the century. These factors threaten food security and the livelihoods of millions of farmers who are heavily dependent on rain-fed agriculture. Water-efficient cropping systems present a viable solution to these issues. Key strategies identified include crop diversification, the use of appropriate crop varieties, conservation (minimum/zero) tillage, traditional water harvesting techniques (Zai and Half-moon pits), and agroforestry. Crop diversification and the utilization of adapted crop varieties empower farmers to overcome the constraints of regions with brief rainy seasons and growing periods. These tactics bolster resilience to drought and boost overall crop performance. Conservation tillage practices aid in preserving soil health while retaining crucial soil moisture. Indigenous water harvesting techniques keep soil water and nutrients near crop roots, markedly enhancing crop production in difficult environments. Agroforestry, the practice of integrating trees into farming landscapes, provides numerous advantages, including shading, erosion prevention, and improved moisture conservation. These approaches contribute to both sustainable crop production and environmental sustainability, addressing Sustainable Development Goals (SDGs) of 1 (no poverty), 2 (zero hunger), and 13 (climate action)
