1. Summary of the impact

The impact of Geography research at the University of Lincoln is on malaria control strategy across sub-Saharan Africa, focusing on Zambia, achieved by linking the physical drivers of transmission (water for breeding by vector mosquitoes) with epidemiology, through new data and process understanding. This research has shown the Zambian Ministry of Health why malaria has not responded to their public health interventions in large areas of the country, leading to new understanding that additional, environmentally tailored, mosquito-control strategies will be required in some areas to achieve their national target for elimination of this disease. The research produced modelling and maps to identify these areas for National and Provincial Medical Services. Capacity for this geographical approach to malaria control, also relevant to other diseases and health risks, has been increased in the region though co-working with partners.

2. Underpinning research

This case study relates to research conducted at Lincoln since July 2017 working with an international, interdisciplinary team of researchers from the UK, Zambia and Canada, and partner organisations (Zambian Ministry of Health [MoH]; Zambezi Water Resources Management Authority [WARMA], University of Barotseland [UBL] and the Zambezi EcoHealth Partnership [ZEP]). The research to which this case study refers is published in Cross et al (2020) [3.1] and Smith et al (2020) [3.2], with an accompanying popular article in Smith and Thomas (2020) [3.3].

Research context

Controlling the mosquitoes that transmit malaria (vectors) is one of the main ways to prevent and reduce the disease. Concerted national malaria control efforts in Zambia (such as bednets and indoor residual spraying of houses with insecticides), have led to a nationwide decline in parasite prevalence among children under 5 from 22% to 9% between 2006 and 2018. However, in some areas, such as Western Province (population 1.1m people) these interventions have not led to reductions and prevalence amongst under-5s in 2019 was 10%, twice as high as 2010 levels. Ecologically, the region is dominated by the Barotse floodplain, comprising a vast network of wetlands flooded seasonally by the Zambezi River and its tributaries: we investigated the relationship between this environment and transmission in order to understand the increase in malaria in the Province.

Malaria vectors are mosquito species of the genus Anopheles, with a few considered ‘primary vectors’ (human specialists, highly efficient vectors of human malaria parasites, main role in transmission) whereas others are ‘secondary vectors’ (take blood from a range of vertebrates, inefficient vectors, minor role in transmission). This is an important distinction in public health as primary vector species in sub-Saharan Africa tend to bite humans at night and indoors, so are susceptible to bednets and indoor residual spraying of insecticides, whereas secondary vectors predominantly bite humans outdoors during the day and at dusk, and so may evade these interventions. Traditionally, malaria control in sub-Saharan Africa has not been concerned with riverine environments as they rarely provide suitable breeding habitat for primary vectors, which breed in small ephemeral water bodies (e.g. puddles) associated with seasonal rain. Water in riverine habitats tend to be too deep, cold and fast flowing for primary vector species.

UoL research

To address these issues, Lincoln research combined field data collection in Sep-Nov 2017 to Apr-June 2019 in wet and dry seasons (Zambezi bathymetry, mosquito surveys stratified spatially by hydrogeomorphology, remote sensing ground control); time series radar and optical remote sensing of habitats, LISFLOOD modelling of the Zambezi seasonal inundation; large sample, high-throughput genetic sequencing of mosquitoes and climate-transmission modelling. This facilitated detailed comparison of taxon-specific abundance patterns in vectors between ecological zones differentiated by hydrological controls.

We discovered [3.1] both an unexpectedly high species diversity of vectors in Western Province and that almost all were secondary vector species, previously thought incapable of maintaining high levels of transmission. We also showed these species were breeding in habitats unsuitable for primary species, being widespread and abundant in floodplains along river margins and associated hydromorphological features. We concluded that these extensive habitats therefore support residual transmission, over much longer seasons, and that in many areas significant levels of transmission is by secondary vectors. This provided an explanation for the continued high prevalence of malaria in the Province and has important consequences for future vector control by the MoH.

It was therefore important to map these hydroclimatic zones across Zambia. To address this problem, we used downscaled daily climate predictions from seven GCMs to run a continental-scale hydrological model for a process-based representation of mosquito breeding habitat availability. A complex pattern of malaria suitability emerges as water is routed through drainage networks and river corridors serve as year-round transmission foci [3.2, 3.3]. Using this model, we produced (report to MoH) national maps of malaria transmission by season length and estimates for each province of the areas and populations at risk in these zones, including under projected climate change [3.2, 3.4].

4. Details of the impact

The research was designed to achieve impact by co-working with the Zambia Ministry of Health (MoH) and partners throughout. Co-working included: on project aims and study design (workshops in Lusaka and Western Province); planning, adapting and participating in field data collection (MoH officers and UBL BSc Environment and Health students), analysis, interpretation, and preparation of published papers (MoH officers are co-authors, see [3.1]). Throughout the study regular progress meetings were held in Western Province, chaired by the Provincial Medical Office, until Covid19 restricted travel, thereafter via internet. Macklin visited Western Province in May 2019 and Thomas in November 2019.

The primary and most direct impact of this research [3.2] is the increased knowledge within the policy making community that seasonal flooding along major rivers and floodplains extends malaria transmission seasons [5.1, 5.2]. More specifically, our research was the first to determine that such flooding extends transmission through secondary vector species; a key aspect that had never previously been considered, leaving a significant gap in malaria prevention strategies.

Other key contributions to strategy making arise from the national/provincial maps of transmission season zones from hydroclimate modelling produced by this research [3.2] which show the areas that need to be considered, and the fine resolution mapping of vector species distribution and abundance in relation to hydrological controls [3.1] is at the operational scale of interventions (village) for use in forward planning [5.2]. The MoH report that our research provided:

“new information on transmission in large areas of the country that will help us to understand trends in malaria cases and our thinking about future control strategies…..Our goal of malaria elimination remains a top priority for health in Zambia and the results from this research make a significant contribution to this effort” [5.1]

As a result, the MoH are now alert to a fundamental issue in vector control, which they are now able to take steps towards addressing in pursuit of the national malaria elimination goal [5.1].

Further impact from this research arises through capacity building for environment and health in Western Province, through field training and use of technology. The collaboration was facilitated by the Zambezi EcoHealth Partnership (ZEP), a partnership led by the MoH, WARMA and the Canadian Coalition for Global Health Research (CCGHR), a knowledge network for global health equity active in 49 countries and involving over 20 Canadian Universities. In this research, a project GIS of source data, field results and analyses generated by UoL research was freely shared to ZEP partners as a ‘knowledge platform’. This high quality, high resolution environmental information has formed the basis for new, spatial, approaches to health priorities in the Province other than malaria [5.1, 5.2, 5.3, 5.4]. This collaboration has also contributed to successful applications for external funding for PhD training of Zambian physicians and health workers from Western Province in Canada, through the award of QE2 scholarships to the University of Waterloo bringing a range of capacity and capability impacts:

“The research you have led … has had a significant impact on the Province’s health services approach to the environmental and ecological challenges it faces, particularly from malaria. The geographic, technical ‘knowledge platform’ your research has delivered to ZEP partners has formed the basis for new approaches to other health challenges such as strategies around access to health facilities in flooding landscapes. I am currently working with physicians and researchers from Zambia who are conducting PhD research in my department using this platform to address climate-related challenges to HIV treatment, maternal and child health care and food security. …Your research has therefore contributed impact through an increased capability and capacity of the health system in Western Province to work with technical developments in environmental mapping relevant to public health” [5.3]

Our research also included training and experience in fieldwork (GPS, study design, sampling, data recording, field logistics) for local UBL students (104 student-days for 6 students) [5.4].

1. Summary of the impact

Governments around the world are struggling to tackle climate change, with predominantly top-down approaches that have limited opportunities for citizens to engage in and influence policy change. To address this challenge – grounded in established expertise in the science of climate change – researchers from Lincoln are exploring ‘Citizen Social Science’ as a way to bring citizens and experts together to co-produce both climate research and policies that build on citizens’ values, knowledge and experiences. Whilst limited by Covid-19, this combination of research has already influenced local climate policy, enhanced knowledge and awareness of the role citizen social science can play in tackling climate change, and informed climate conversations around the globe, through the communities of the Anglican Church.

2. Underpinning research

The Fifth Assessment Report prepared by the Intergovernmental Panel on Climate Change states that the warming of the climate is unequivocal and that human influence on the climate is clear. However, despite this report being published in 2014, existing government policy approaches around the world are struggling to limit global temperatures below the 1.5 to 2°C Paris target. The predominantly top-down policy approaches are being called into question, not least by the recent school climate strikes, widespread public protests and declarations by public bodies at all levels of climate emergencies. Research at the University of Lincoln aims to address this policy challenge, by combining expertise in climate science with new research on the benefits of ‘citizen social science’.

Professor Edward Hanna is globally recognised for his research on ice-sheet mass balance and consequences for global sea-level rise (Section 3:1,2,3). By examining the meltdown rates of the Greenland and Antarctic Ice Sheets, the work of Hanna’s team has demonstrated the necessity to limit global warming to 1.5°C above pre-industrial levels in order to avoid potentially catastrophic tipping points. Professor Mark Macklin has conducted pioneering research into flood risk under changing climate based on new long reconstructions from sedimentological archives (Section 3:4). As well as being directly relevant for millions of people in low-lying coastal communities including Lincolnshire and Polynesia, who are directly affected by rising sea levels and floods and connected (through the Moana: Water of Life conference) in the impact work below, these findings have informed the work of other members of the research team, who are exploring why existing climate mitigation and adaptation policy approaches are not working and are therefore working on identifying potential alternatives.

Dr Kythreotis’ and Dr Mercer’s research into climate policy responses has found that traditional top-down climate change policies have limited citizen agency and disregard citizen’s concerns, values and goals for their communities. This has led these researchers to propose the alternative approach of ‘citizen social science’, as a way to more directly engage members of the general public, and especially young people, in mitigating and adapting to future climate change. The model brings citizens and experts together to work collaboratively to co-produce climate research and policies that build on citizens’ values, knowledge and experience and highlights the vital role of engaging ordinary members of the public in finding solutions to problems posed by human-induced climate change. The findings also identify ways to overcome existing barriers to effective citizen action by promoting local climate-change issues with scientists and policymakers. [Section 3:5,6]

Taken together, this body of research creates a powerful platform for impact, grounding citizen social science strongly in recognised climate science expertise and presenting alternative approaches for effective climate action.

4. Details of the impact

The team’s research into Citizen Social Science demonstrates that bridging the gap between citizens and young people with scientists, policymakers and other experts, enables better-informed decision-making that can positively influence policy and its implementation at local to global levels. Grounded in globally recognised climate science expertise, the team has used its research to influence local policy decisions, enhance knowledge and awareness of the role that citizen social science can play in tackling climate change, and inform climate conversations around the world.

Influencing local policy decisions

A collaboration between the City of Lincoln Council, Siemens, Transition Lincoln and the team of researchers at University of Lincoln has led to establishment of the new Lincoln Climate Commission (LCC, https://www.lincolnclimate.org.uk/), co-founded by Kythreotis and advised by Hanna and colleagues. Since being launched in 2019, the Commission has drawn directly on research presented by the University of Lincoln research team – both on climate change and flood risk and on citizen social science – to lobby the City Council to adopt a net zero carbon target by 2030, as well as thinking of new ways to make a more climate-resilient Lincoln, both of which have been successfully incorporated into council policy. As Lincoln City Council Leader, Councillor Metcalfe, has said, “As LCC Chair, I feel that the scientific evidence and expert judgement presented by University of Lincoln researchers, including recent research results on climate change and flood risk by Profs. Hanna and Macklin and "citizen social science" led by [Dr. Kythreotis], has influenced the City Council in adopting a net zero carbon target by 2030, as well as thinking of new ways to make a more climate resilient Lincoln.” [5.1] Kythreotis has also liaised with the Place-Based Climate Action Network ( https://pcancities.org.uk/), resulting in the LCC becoming one of just eleven full members of the UK network of PCAN climate commissions.

The team’s research also influenced the development of the Diocese of Lincoln Environmental Policy, launched by the Diocese of Lincoln on 1 September 2019 as part of our co-run Moana Conference. The Rt. Revd. Dr. David Court, Acting Bishop of Lincoln, wrote that “The University of Lincoln was consulted and excellent sense checking provided through the expertise of Professor Edward Hanna and Rebecca Forster who supported the writing of the policy Introduction and refining of the twelve goals…Learning from [the] Moana [Conference] has resulted in carbon footprint questions being integrated into planning of further diocesan events

and hospitality.” [ 5.2].

Enhancing knowledge and awareness of the role citizen social science can play in tackling climate change

Drawing on our collective research, and working in collaboration with Bishop Grosseteste University and local representatives of the Church of England – for whom limiting the impacts of anthropogenic climate change is essential to their faith – the research team was approached in 2018 by the then Bishop of Lincoln (via the UoL DVC Prof. Toby Wilkinson) to co-organise and host an international conference on addressing human-induced climate change, called “Moana Water of Life? Navigating Climate Change for Planetary Health”. BGU were co-organisers of the conference and resulting book [5.3]. The conference, held in August/September 2019, brought together around 150 diverse stakeholders from the UK, USA, Polynesia and New Zealand, including physical and social scientists, religious leaders, ‘green’ businesses, students and members of the general public. As well as exploring the new model of citizen social science with this diverse group of participants, the conference also focused on engaging with the delegates and their views on the issues. The team used questionnaires, a ‘conversation wall’ and a photographic art exhibition by Project Pressure ( www.project-pressure.org) to prompt delegates to question their preconceptions on how they deal with climate risks to planetary health and individuals’ lifestyles. This is evidenced by quotes from participants including: “What all the presenters have shared has challenged the churches that it is time to work together to combat climate change…we are here to try to save the world”; “A lot of ideas and influences for the ongoing work with a climate strategy for the church of Sweden”; “I am a primary teacher and have been inspired to do more work with the children around making connections with, and having respect for, our planet.”; and “I have remembered why I embarked on this journey in the first place” (Conference feedback sheets, **[5.4]**). These quotes bolster the concept of Citizen Social Science as a tool to engage disparate and diverse communities, including major religious organisations, in addressing the climate emergency. Further conference feedback includes: "The Moana: Water of Life conference was distinctive in many ways…One singular trait that stands out, with the perspective of time and geographical distance, was the way the conference conversation revealed the multi-faceted nature of climate change/emergency, that scientists, faith-motivated individuals and members of the local community can interpret climate change in vastly different ways, yet reach the same conclusions concerning the urgency for addressing our planet’s needs, for humankind and the planet. This melding of very different voices and perspectives was rich and multi-layered, and the cross-over of these worlds, and the conversations that we had, were truly unique in space and time." [5.5]. Dr. Emily Colgan (Trinity Theological College) wrote “The Moana: Water of Life conference (and the subsequent publication)…was groundbreaking…it was a huge privilege to participate in this project and the ripples of this work continue to spread and impact communities around the world” [5.6].

Informing climate conversations around the globe, through the communities of the Anglican Church

The connection with the Anglican Community came through the “Moana Water of Life…” Conference, creating an opportunity for the team’s research to reach into one of the biggest global communities of more than 85 million people worldwide. The conference was cited as an ‘example of good practice’ in the General Synod GS 2159 “Climate Emergency and Carbon Reduction Target” background paper to the February 2020 Church of England policy to adopt a Net Zero Carbon emissions target of 2030, relative to a much more conservative and arguably inadequate original target date of 2050. The Rt. Rvrd. Dr. David Court, Acting Bishop of Lincoln, wrote: “The reasoning for the policy update referenced our learning from Moana conference…It is likely that the shared knowledge for Moana contributed to the receptiveness of ambition within this vote.” The Metanoia Festival Organising Committee wrote that *“without Moana, Metanoia [Festival, to be held in Grantham in October 2021,* https://trinitygrantham.weebly.com/updates/metanoia-climate-festival-dates ] would not have happened, the influence of the Moana Conference has already been significant” [5.7]. Following the conference, Hanna co-edited a resulting first-of-its-kind book, “Science, Faith and the Climate Crisis” (Emerald; June 2020) which uniquely explores the climate science-faith interface. This book brings together conference contributions with reflections by leading academics (including a chapter by Mercer and Kythreotis on Citizen Social Science), religious leaders and other conference delegates and with a foreword from the Archbishop of Canterbury (Justin Welby), who also opened the Conference. In his Foreword, Archbishop Welby wrote: “This book illustrates how when different voices are listened to carefully, new perspectives, opportunities and solutions can begin to be found” [5.3] . The team has been able to use this book and a resulting online brochure available at https://www.lincoln.ac.uk/home/media/responsive2017/collegeofscience/schoolofgeography/research/Science,,Faith,and,the,Climate,Crisis.pdf to encourage and provide materials for churches to lobby their congregations and governments for meaningful action on climate mitigation and adaptation, with a focus on using the scale of the Anglican community to effect change. For example, Bishop Marc Andrus, Bishop of the Episcopal Diocese of California, has added the book to a list of climate action resources shared with a group of about sixty climate-conscious bishops of the Episcopal Church in the USA. Bishop Andrus has said “Given the monumental, indeed unprecedented scale of threat posed by human-caused climate change, the Lincoln University led conference ranks high on my list of responses…Science, Faith and the Climate Crisis provides insights and information that can help this global body of religious leaders [attendees of the next Lambeth Conference – decadal meeting of global archbishops] engage the climate crisis more effectively.” [5.8]

While progress has been slowed by Covid-19, which has pushed back the timing of the Lambeth Conference by two years to summer 2022, the impact outlined above has made our team determined to continue its work on the role that citizen social science can play in dealing with climate risks.
