An investigation of the basement complex aquifer system in Lofa county, Liberia, for the purpose of siting boreholes

Liberia is recovering from a 14 year civil war and only 51% of the rural population has access to safe drinking water. Little hydrogeological knowledge survives in Liberia, increasing the difficulty in successfully siting new boreholes. An understanding of the local hydrogeological environment is therefore needed to improve borehole site selection and increase success rates. This research provides a semi-quantitative characterization of the hydrogeological environment of the basement aquifer in Lofa county, Liberia. Based on literature review and analysis of borehole logs, the study has developed a conceptual hydrogeological model for the local conditions, which is further characterized using 2D geoelectrical sections. Groundwater is predominantly obtained from the saprolite and underlying fractured bedrock, but specific capacities (median 281 l h-1 m-1; 25th and 75th percentile of 179 and 490 l h-1 m-1, respectively) are constrained by the limited thickness of the saturated saprolite. This study has shown that the groundwater resources in the crystalline basement in this part of Liberia conform to the general conceptual model, allowing standard techniques used elsewhere for siting and developing groundwater to be used

Media exposure to mass violence events can fuel a cycle of distress.

The established link between trauma-related media exposure and distress may be cyclical: Distress can increase subsequent trauma-related media consumption that promotes increased distress to later events. We tested this hypothesis in a 3-year longitudinal study following the 2013 Boston Marathon bombings and the 2016 Orlando Pulse nightclub massacre using a national U.S. sample (N = 4165). Data were collected shortly after the bombings, 6 and 24 months post-bombings, and beginning 5 days after the Pulse nightclub massacre (approximately 1 year later; 36 months post-bombings). Bombing-related media exposure predicted posttraumatic stress symptoms (PTS) 6 months later; PTS predicted worry about future negative events 2 years after the bombings, which predicted increased media consumption and acute stress following the Pulse nightclub massacre 1 year later. Trauma-related media exposure perpetuates a cycle of high distress and media use

To Bridge the Gap? Voluntary Action in Primary Schools

Voluntary action has long played a role in state education, with Parent Teacher Associations being one of the most common forms of charitable organisation in England. However, education policy, driven by a growing free-market discourse and policy initiatives such as localism, is increasingly pushing for greater voluntary action. This article explores the distribution of voluntary action for primary schools in one local authority area in England. Drawing upon primary data from 114 questionnaires completed by head teachers and secondary data from the financial records (2013/14) of 380 primary schools, we find evidence of considerable uneven dispersal of voluntary action between schools. These disparities are related to factors including school size, location, leadership ideology and the socio-economic profile of the school. The consequence of this uneven distribution is that schools catering for more affluent communities are more likely to have additional resources than those with poorer profiles

To Bridge The Gap? Voluntary Action in Primary education

Voluntary action has had a long history in the education of our children, bringing a wide range of positive benefits to schools, children, staff, the local community and volunteers alike. Voluntary action enables schools to draw upon a wide range of additional skills and resources, can strengthen a school community and engage children in philanthropic activity from an early age. Schools continuously highlight how much they value the commitment, passion, skills and expertise brought into their community by volunteers, and recognise the advantages of fundraising in terms of community engagement, fostering philanthropic activity in children and providing additional income for the school. Unsurprisingly voluntary action in education tends to be viewed as a positive and good thing, and is increasingly encouraged within policy and practice. This research suggests that voluntary action in primary schools is indeed becoming progressively central to school activities, with many primary schools keenly seeking to strategically engage and grow this area of activity. Schools report purposefully fostering engagement of volunteers to help increase teacher capacity, support children through one-to-one activities and provide additional resources for both core and extra-curricular activities. Furthermore, schools highlight increasing focus on their fundraising activities to help support depleting budgets and growing demands. There is however very little research in the UK which explores voluntary action in education. The limited research that is available suggests significant disparities in how additional resources from voluntary action are dispersed within the UK context. This is supported by research from across Europe and the United States. Therefore this project sets out to be an exploratory study of this area to ascertain how actively schools engage with this voluntary action and what barriers they may face. The local authority of Kent was chosen as a focus for this study. Through analysis of financial data of over 600 primary schools, questionnaires completed by 114 of these and interviews with 4 case study schools this research presents initial findings and trends in activity under the separate headings of volunteering and philanthropic activity (fundraising)

Sand dam contributions to year-round water security monitored through telemetered handpump data

Sand dams are a form of rainwater harvesting, prolific in arid and semi-arid lands. Water is provided partly via handpumps, which, as the only improved method of abstraction from sand dams, are important for drinking water security. Accelerometers and cellular transmitters were fitted to 30 handpumps by the Africa Sand Dam Foundation (ASDF) in 2019 to monitor the use and reliability of the handpumps by recording hourly water volume abstracted. Data from April 2019 to October 2021 for 26 of these sites, alongside qualitative data, were analysed and each handpump’s contribution to year-round water security was explored, focusing on the long dry season when water supply from other sources is compromised. Abstraction was over 20 times higher in the long dry season than in any other season, and at sites with higher salinity, higher livestock use, and larger dam wall area. At 21 wells, abstraction was still being recorded at the end of at least one long dry season; however, high spatial and temporal heterogeneity between pumps and seasons means that not all sand dams deliver reliable water supply year-round. Quantifying the contribution that sand dams make to water security is crucial for understanding their resilience against a changing climate and can aid decision makers when choosing the most appropriate water management technique. Knowledge of temporal and site heterogeneity in abstraction can inform when other water sources need increasing and can help with sand dam design optimisation. Overall, our results indicate the positive contribution that sand dams make to year-round water security through the water that is abstracted through handpumps.Engineering and Physical Sciences Research Council (EPSRC): EP/S022066/1 Sand Dams Worldwid

Advancing the use of scenarios to understand society’s capacity to achieve the 1.5 degree target

With a range of potential pathways to a sustainable future compatible with the Paris Agreement 1.5 °C target, scenario analysis has emerged as a key tool in studies of climate change mitigation and adaptation. A wide range of alternative scenarios have been created, and core amongst these are five socio-economic scenarios (Shared Socio-economic Pathways or SSPs) and four emission scenarios (Representative Concentration Pathways or RCPs). Whilst mitigation scenarios (the Shared Policy Assumptions, or SPAs) have been developed for each SSP-RCP combination, describing the actions necessary to match the climate pathway of the RCP, there has not yet been a systematic approach to address whether and how these actions can be enabled in practice. We present a novel and transferable framework to understand society’s capacity to achieve the 1.5 °C target, based on four participatory case studies using the SSP-RCP scenarios. The methodology builds on a framework for categorising different types of societal capitals and capacities and assessing their impact on the potential to implement different types of mitigation actions. All four case studies show that SSP1 has the highest potential to reach the target. Although environmental awareness is high in both SSP1 and SSP4, continued social inequalities in SSP4 restrict society’s capacity to transform, despite economic growth. In the two least environmentally-aware SSPs, SSP3 and SSP5, the transformation potential is low, but the view on capitals and capacities nonetheless helps identify opportunities for actors to develop and implement mitigation actions. The study highlights that techno-economic assessments of climate strategies need to be complemented by consideration of the critical role played by social and human capital, and by societal capacity to mobilise and create these capitals despite different socio-economic trends. These capitals and capacities are essential to enable the rapid innovation, behavioural change and international co-ordination needed to achieve the 1.5 °C target
