Most outdoor public spaces are underutilized during extremely hot weather. In the absence of adequate shading, these areas become high-risk zones, posing significant health risks, particularly for vulnerable populations such as the elderly and children. Some cities aim to retrofit public spaces as part of their heat action plans to make them more useable and thermally safe during extreme heat events. However, cities lack the relevant scientific data to inform such plans and often have no means of evaluating and quantifying the likely benefits from specific redesign strategies. To address this challenge, we evaluated the outdoor thermal regime in Mesa, Arizona, on a human scale. We generated high-resolution Mean Radiant Temperature (MRT) data using surface models developed using LiDAR point clouds and meteorological forcing data from a local weather station. We modified the surface models to reflect future scenarios and exposure settings following the plans for modifying vacant lots in the city. MRT in most vacant lots without shading reaches values as high as 80 °C during the day. We observed that the heat burden was reduced by about half at locations with shading from existing trees. Future work will investigate how the redesign strategies improve the useability of the spaces under different exposure settings.

Climate change, population growth, rapid urbanization, shifting dietary patterns, and economic development pose significant challenges to food security, particularly in the Global South. Addressing these challenges involves efforts aimed at sustainable agricultural intensification (SAI), especially for smallholder farmers in marginalized regions. However, knowledge gaps persist regarding smallholder farmers’ access to water for SAI, particularly in arid and semi-arid agroecological zones. This study investigates smallholder farmers’ access to water for SAI in the Guinea and Sudan Savannah Agroecological Zones (SSAZ) of Ghana. Data were collected from 698 smallholder farmers across 25 communities using a structured questionnaire and geospatial techniques. The analysis employed cost distance analysis, factor analysis, and multinomial-ordered logistic regression. Findings indicate that the average distance travelled to access water from a dam or a river was 11 km and 9 km, respectively. Most respondents reported low to moderate water access for SAI. Key factors influencing water access included soil type, vegetation, and the distances to dams and rivers. To improve water access, it is recommended that smallholder farmers be educated on effective soil and water conservation techniques. Additionally, both government and non-governmental organizations should focus on building community-level dams to increase water availability for sustainable agricultural intensification.

Background: Anaemia has become a major public health concern among women in Sub-Saharan Africa (SSA). However, little is known about the spatial disparities in anaemia prevalence and their associated factors among pregnant women in the region. This study analysed the spatial disparities in anaemia and their associated factors among pregnant women in rural and urban settings in SSA. Methods: This is a secondary analysis of the most recent demographic and health surveys of 26 countries in SSA. Spatial autocorrelation and hotspot assessment were conducted, while a multivariate logistic regression model was used to identify demographic factors associated with anaemia. Results: Anaemia was reported among ~50% of pregnant women in urban and rural areas of SSA. The hotspot analysis identified the West African sub-region as having a higher concentration of anaemia cases in rural settings. In urban areas, the odds of anaemia were significantly higher among pregnant women in their second trimester (Adjusted OR = 2.39, CI = 1.99, 2.76). On the other hand, pregnant women in their third trimester (Adjusted OR = 1.98, CI = 1.77, 2.22) and those who had taken intestinal parasite drugs (Adjusted OR = 1.12 CI = 1.02, 1.23) had a higher likelihood of having anaemia in rural areas. Pregnant women aged 35–39 years (Adjusted OR = 0.52, CI = 0.33, 0.81) and those aged 40–44 years (Adjusted OR = 0.69, CI = 0.50, 0.95) had a lesser likelihood of having anaemia compared to women aged 15–19 years in urban and rural areas respectively. Compared to Congo DR, Benin (OR = 2.22, CI = 1.51, 3.28) and Mali (OR = 3.71, CI = 2.73, 5.05) had higher odds of anaemia in urban and rural areas respectively. Conclusions: Spatial disparities in anaemia persist among pregnant women in rural and urban settings in SSA. Prevailing spatial variations in anaemia may be addressed by specialised interventions considering the contextual residential settings and socio-economic factors highlighted in this study.

Background: Evidence shows that intimate partner violence (IPV) occurs more frequently in sub-Saharan Africa (SSA) than in other regions of the world. However, limited empirical studies exist on the help-seeking behaviour of women who had experienced IPV in SSA. This study aimed to examine the help-seeking behaviour of women who had experienced IPV in SSA and the factors associated with their inability to seek help after experiencing IPV. Methods: This is a quantitative study based on data from the latest demographic and health surveys (DHS) of 24 SSA countries. A sample of 53,446 women aged 15–49 years was included in the study. Associations between women’s background characteristics and their help-seeking behaviour after experiencing IPV were examined using proportions and multivariate logistic regression models. Results: Overall, 60.7% of the sample did not seek help after experiencing IPV. Women's inability to seek help for IPV was highest in Mali (80.4%) and lowest in Tanzania (43.1%). Women’s level of education, wealth status, marital status, age, occupation, and country of residence had significant associations with ‘not seeking help’ for any type of IPV. Those who experienced generational violence (AOR = 1.26, CI = 1.19, 1.33) and those who justified wife-beating (AOR = 1.09, CI = 1.07, 1.15) had higher odds of not seeking help for any type of IPV compared to those who did not experience generational violence or did not justify wife beating. Women who experienced emotional violence (AOR = 0.53, CI = 0.51, 0.55) and physical violence (AOR = 0.74, CI = 0.70, 0.76) had lower odds of not seeking help for any type of IPV compared to their counterparts who did not experience these types of violence. Conclusion: Women’s inability to seek help for IPV is common in many SSA countries. This study shows that several socio-demographic factors, such as women's age, educational levels, wealth status, and marital status are associated with their inability to seek help for IPV. Additionally, women's justification of wife beating and experience of generational abuse are strongly associated with their inability to seek help for IPV. These factors need to be considered critically in IPV interventions in SSA.

Introduction: Evidence shows that most women in Ghana do not meet the minimum 8-contact model for antenatal care as recommended by WHO with only 31.2%-41.9% of them meeting the recommendation. To the best of our knowledge, no study in Ghana has examined women’s noncompliance with the WHO’s recommended 8-contact model for antenatal care using geospatial analysis, as this study sets out to do.Methods: We sourced data from the recent version of the Ghana Maternal Health Survey which was executed in 2017. A sample of 10,077 women with complete data participated in this study. The link between the explanatory variables and the outcome variable was investigated using binary and multivariate logistic regression models and Spatial analyses such as spatial autocorrelation (Moran's I), hotspot, cluster and outlier analysis, and geographically weighted regression were conducted using ArcMap version 10.7.Results: Districts found in the north-eastern and south-western parts of the country were more likely to experience noncompliance with ANC. Women staying within the middle belt without health insurance were more likely (17–29%) to be noncompliant with ANC. Women with low community socioeconomic status were found to be more likely (17–34%) to be noncompliant with ANC in the eastern parts of Ghana.Conclusion: The study has shown that in order to achieve targets one and three of Sustainable Development Goal 3, the government of Ghana, the Ministry of Health, together with the Ghana Health Service may have to intensify health education in the identified areas to highlight the importance of adherence to the WHO recommendations on ANC 8-contact model.

Background: Several studies have shown that unskilled birth attendance is associated with maternal and neonatal morbidity, disability, and death in sub-Saharan Africa (SSA). However, little evidence exists on prevailing geospatial variations and the factors underscoring the patterns of unskilled birth attendance in the region. This study analysed the geospatial disparities and factors associated with unskilled birth attendance in SSA.Methods: The study is based on data from thirty (30) SSA countries captured in the latest (2010–2019) demographic and health surveys (DHS). A total of 200,736 women aged between 15–49 years were included in the study. Geospatial methods including spatial autocorrelation and hot spot analysis as well as logistic regression models were used to analyse the data.Results: There were random spatial variations in unskilled birth attendance in SSA, with the main hotspot located in Chad, whereas South Africa and the Democratic Republic of Congo showed coldspots. Residence (urban or rural), wealth status, education, maternal age at the time of the survey and age at birth, desire for birth, occupation, media exposure, distance to a health facility, antenatal care visits, and deaths of under-five children showed significant associations with unskilled birth attendance.Conclusion: Random geospatial disparities in unskilled birth attendance exist in SSA, coupled with various associated socio-demographic determinants. Specific geospatial hotspots of unskilled birth attendance in SSA can be targeted for specialised interventions to alleviate the prevailing disparities.
