    Access to safe and reliable water supplies is a key goal for households and governments across most of Africa. Groundwater reserves can play a critical role in achieving this, yet risks of contamination and over-abstraction threaten to undermine the resilience of this supply. A rapidly rising trend for privately-developed wells and boreholes raises additional concerns about the vulnerability of water supplies to natural or man-made environmental shocks. The potential scale of the situation is particularly marked in Nigeria where the use of boreholes has increased exponentially since 1999 (from 10% of the population to 38% in 2015), with most other forms of water supply, notably piped tap water, falling. Developing effective groundwater management approaches that build the resilience of communities is challenging, not least given the range of different actors involved, their competing interests and demands, and variations in the hydrogeological environment. Insights from resilience studies in social science emphasise how the resilience of ecological resources to shocks and change is critically linked to the adaptive capacity of social systems and their agents. Choices made now have long-lasting effects, yet these choices are little understood. Understanding the choices made by consumers, drillers and policy actors requires a strong interdisciplinary dimension and argues for new perspectives as to how the resilience of communities and societies might be built. The project brings together a unique interdisciplinary collaboration between academics from the UK and Nigeria working in the fields of economic geography, psychology, hydrogeology and journalism studies

    Domestic groundwater abstraction in Lagos, Nigeria: a disjuncture in the Science-Policy-Practice Interface?

    Get PDF
    The rapid development of groundwater systems as part of urban water supplies around the globe is raising critical questions regarding the sustainable management of this essential resource. Yet, in many major cities, the absence of an effective policy regime means that the practice of groundwater exploitation is driven by the actions of domestic households and drilling contractors. Understanding what shapes the decisions and practices of these actors, their understandings of the groundwater resource and the extent to which scientific knowledge shapes this understanding, is an area of critical importance that is currently under-researched. Using a mixed-methods methodology, the paper explores domestic practices of groundwater abstraction in Lagos, Nigeria. It finds that there is a disjuncture between the households who are actively shaping exploitation of the groundwater resource on a day-to-day basis and science and state actors. This disjuncture results in household decisions that are influenced by commonly held, but potentially outdated, perceptions of the groundwater resource rather than scientific evidence or policy instruments. The unseen nature of groundwater resources effectively renders the scale of changing groundwater conditions invisible to households and the state, adding to the challenge of influencing practice. Addressing this disjuncture requires not just more scientific knowledge, but also the active construction of interfaces with, and between, non-state actors through which knowledge can be confronted, discussed and shared

    Individual water sourcing: understanding risks and resilience to groundwater resource abstraction in Nigeria

    Get PDF
    Across much of Africa, domestic water supplies are increasingly dependent on groundwater reserves. As the cost of accessing these reserves fall, expertise becomes more widely available and incomes rise there is a rising trend towards the private commissioning of boreholes and wells. This nascent shift towards a distributed and increasingly individualised water supply may have many implications for the resilience of communities to future environmental shocks, which are, as yet, under-explored. Drawing on the case of Nigeria and new interdisciplinary research, this paper addresses this gap, through a specific focus on understanding the behaviour and choices of individuals and other key stakeholders which underpin this trend. It also seeks to understand the possible implications of this for the resilience of associated social and ecological systems

    Placing people at the heart of climate action

    This is the final version. Available on open access from Public Library of Science via the DOI in this record. Profound societal change along with continued technical improvements will be required to meet our climate goals, as well as to improve people’s quality of life and ensure thriving economies and ecosystems. Achieving the urgent and necessary transformations laid out in the recently published IPCC report will require placing people at the heart of climate action. Tackling climate change cannot be achieved solely through technological breakthroughs or new climate models. We must build on the strong social science knowledge base and develop a more visible, responsive and interdisciplinary-oriented social science that engages with people and is valued in its diversity by decision-makers from government, industry, civil society and law. Further, we need to design interventions that are both effective at reducing emissions and achieve wider societal goals such as wellbeing, equity, and fairness. Given that all climate solutions will involve people in one way or another, the social sciences have a vital role to play.Economic and Social Research Council (ESRC

    Risks and resilience of private boreholes in Lagos, Nigeria

    Get PDF
    Water security is one of the most pressing risks facing the world. In urban areas, rapidly growing population coupled with rising incomes, falling costs, and often an absent or unreliable public water supply, mean that increasing numbers of households are choosing to install private boreholes to meet their domestic water needs. This trend is particularly prevalent in emerging global mega-cities such as Lagos, Nigeria. This multidisciplinary study begins to address the question: Does the proliferation of private boreholes strengthen or weaken the resilience of Lagos and its residents to future environmental shocks

    Visual Climate Change Communication: From Iconography To Locally Framed 3D Visualization

    Get PDF
    Climate change is an urgent problem with implications registered not only globally, but also on national and local scales. It is a particularly challenging case of environmental communication because its main cause, greenhouse gas emissions, is invisible. The predominant approach of making climate change visible is the use of iconic, often affective, imagery. Literature on the iconography of climate change shows that global iconic motifs, such as polar bears, have contributed to a public perception of the problem as spatially and temporally remote. This paper proposes an alternative approach to global climate change icons by focusing on recognizable representations of local impacts within an interactive game environment. This approach was implemented and tested in a research project based on the municipality of Delta, British Columbia. A major outcome of the research is Future Delta, an interactive educational game featuring 3D visualizations and simulation tools for climate change adaptation and mitigation future scenarios. The empirical evaluation is based on quantitative pre/post-game play questionnaires with 18 students and 10 qualitative expert interviews. The findings support the assumption that interactive 3D imagery is effective in communicating climate change. The quantitative post-questionnaires particularly highlight a shift in support of more local responsibility

    Mitogen-activated protein kinase (MAPK) pathways form the backbone of signal transduction in the mammalian cell. Here we applied a systematic experimental and computational approach to map 2,269 interactions between human MAPK-related proteins and other cellular machinery and to assemble these data into functional modules. Multiple lines of evidence including conservation with yeast supported a core network of 641 interactions. Using small interfering RNA knockdowns, we observed that approximately one-third of MAPK-interacting proteins modulated MAPK-mediated signaling. We uncovered the Na-H exchanger NHE1 as a potential MAPK scaffold, found links between HSP90 chaperones and MAPK pathways and identified MUC12 as the human analog to the yeast signaling mucin Msb2. This study makes available a large resource of MAPK interactions and clone libraries, and it illustrates a methodology for probing signaling networks based on functional refinement of experimentally derived protein-interaction maps

    Understanding risks and resilience of private boreholes in Lagos, Nigeria

    Water security is one of the most pressing risks facing the world. In urban areas, rapidly growing population coupled with rising incomes, falling costs, and often an absent or unreliable public water supply, mean that increasing numbers of households are choosing to install private boreholes to meet their domestic water needs. This trend is particularly prevalent in emerging global mega-cities such as Lagos, Nigeria. Through a series of internet, household, and water point surveys, this multidisciplinary study begins to address the question: does the proliferation of private boreholes strengthen or weaken the resilience of Lagos and its residents to future environmental shocks? A broad internet survey shows that 68% of 500 respondents make use of private boreholes on a daily basis, either as their primary water source or used conjunctively with other sources. Attitudes to groundwater are overwhelmingly positive, with a majority considering this a reliable source in terms of quality and quantity, and agreeing that access to a private borehole increases households’ water security, helping families to cope with possible water shortages in future. The majority of borehole owners perceive no risks associated with long-term groundwater availability, with 89% agreeing that water is abundant and 86% holding the view that borehole owners should be able to abstract as much water as they like. The results of a focused water-point and household survey, carried out at 40 private groundwater sources across Lagos, agree with these findings. Of those surveyed, the majority derive their domestic water from privately owned hand-dug wells and boreholes, and sachet water. Water point users have positive perceptions of the water quality from these sources, with 90% of boreholes and 80% of hand-dug wells thought to provide good quality water. However, water quality analyses show that individual’s perceptions do not always reflect reality. One third of boreholes and over 80% of shallow wells surveyed display unsafe levels of E. Coli. Of those sources perceived as good quality, almost 40% are classed as unsafe for drinking, according to measured levels of E. Coli. The collective enthusiasm for unlimited and expanding groundwater extraction in the city of Lagos coupled with a demonstrated lack of groundwater governance and regulation, while increasing individuals’ resilience to issues of water shortage in the present, may decrease the resilience of the wider community in the long-term. Understanding the role of agency and communicating the potential risks associated with uncontrolled groundwater development, across a range of actors and agencies, may be critical to avoid future conflict between individual and societal resilience to environmental shocks

    Modulation of Interleukin-1 Transcriptional Response by the Interaction between VRK2 and the JIP1 Scaffold Protein

    Get PDF
    Background. Cellular biological responses to specific stimulation are determined by a balance among signaling pathways. Protein interactions are likely to modulate these pathways. Vaccinia-related kinase-2 (VRK2) is a novel human kinase that can modulate different signaling pathways. Principal findings. We report that in vivo, the activity of JIP1-JNK complexes is downregulated by VRK2 in response to interleukin-1β. Also the reduction of endogenous VRK2 with shRNA increases the transcriptional response to IL-1β. The JIP1 scaffold protein assembles three consecutive members of a given MAPK pathway forming signaling complexes and their signal can be modulated by interactions with regulatory proteins that remain to be identified. Knocking-down JIP1 with siRNA resulted in elimination of the AP1 transcriptional response to IL-1β. VRK2, a member of novel Ser-Thr kinase family, is able to stably interact with JIP1, TAK1 and MKK7, but not JNK, and can be isolated forming oligomeric complexes with different proportions of TAK1, MKK7β1 and JNK. JIP1 assembles all these proteins in an oligomeric signalosome. VRK2 binding to the JIP1 signalosome prevents the association of JNK and results in a reduction in its phosphorylation and downregulation of AP1-dependent transcription. Conclusions/Significance. This work suggests that the intracellular level of VRK2 protein can modulate the flow through a signaling pathway and alter the response from a receptor that can be distributed by more than one pathway, and thus contribute to the cellular specificity of the response by forming alternative signaling complexes. Furthermore, the effect might be more general and affect other signaling routes assembled on the JIP1 scaffold protein for which a model is proposed.S.B., M.
