Innovative climate-smart agricultural practices and knowledge scaling-up in vulnerable regions of Benin (INNOCSAB).
Innovative climate-smart agricultural practices and knowledge scaling-up in vulnerable regions of Benin (INNOCSAB).
The project team will investigate to what extend climate-smart agricultural practices and knowledge scaling-up can contribute to building resilience of agro-ecosystems and human systems in West Africa. Studies have shown that most smallholders who rely heavily on agriculture do not always have the knowledge, information and training needed to adopt agroecological measures and sustainable farming systems that support land management. The project will use an innovative approach of scaling the use of climate information through the Participatory and Integrated Climate Services for Agriculture (PICSA), combining existing CSA technologies to adapt and mitigate climate change effects by training extension services, farmers, NGO, and researchers using Climate Smart Villages and Valleys (CSV) and Rural Resource Centers (RRC). We will then assess improvement of the profitability, productivity and sustainability of smallholder farming, household nutritional security and dietary diversity and income generation through integrated crop, tree, and livestock production systems.
Bonomo’s expertise is in the cellular immunology of tolerance and T cells. She has demonstrated the role of thymic epithelium in central tolerance, the escape of unselected T cells in autoimmunity models, and the supportive function of T cells in bone metastases of breast tumors. Her group currently studies the influence of T cells in metastasis; oral tolerance using a probiotic as an adjuvant therapy to prevent Graft vs. Host disease, and, more recently, neuroimmunology of the developing brain and strategies to regulate neuroinflammation. Bonomo’s team studied select monoclonal antibodies in three human cohorts at the emergence of the COVID-19 pandemic: infected patients with household transmission evaluation in health workers and Chagas Disease in COVID-19 patients, looking at humoral, cellular and innate immunity.
At the start of the COVID-19 pandemic, the Sigal lab pivoted to SARS-CoV-2 research and was the first to describe the escape of the Omicron variant from previous immunity.
Sigal received his Ph.D. in Systems Biology from the Weizmann Institute of Science in Israel and was a Postdoctoral Fellow with the Nobel Laureate David Baltimore at the California Institute of Technology, where he worked on HIV cell-to-cell spread and its effects on antiretroviral therapy.
Ugwu’s research seeks to understand how the immune system modulates the outcome of viral infection. It examines the correlates of protective immune response to viral infections such as Lassa Fever virus, SARS-CoV-2, and other endemic viral diseases in West Africa. Findings will be vital for vaccine and therapeutic design, production of diagnostics, and to inform public health policies. Ugwu has vast experience in setting up, training and supervising standardised immune assays such as binding antibody ELISA, virus pseudo type neutralization assay, ELISpot, Luminex multiplex ELISA, cell culture, flow cytometry, western blot, polymerase chain reaction and single-cell RNA sequencing, and can perform all of these assays in both BSL2 and 3 containment facility. He has published and reviewed scientific journals on the immunology of infectious diseases and published the first Lassa immune correlate data generated in-country, demonstrating that both symptomatic survivors and their asymptomatic contacts produce binding and neutralizing antibody responses and T-cell responses that are cross-reactive across different LASV lineages.

Scaling-up Uptake and Effective Use of Climate Resilient Innovations to Address Challenges Affecting Youth-led Agribusinesses in the Chicken Value Chain in Uganda and Burundi
Barbara Mugwanya Zawedde of the National Agricultural Research Organization (NARO) in Uganda and partners will facilitate increased uptake and effective use of climate resilient innovations to address challenges affecting youth-led agribusinesses in the chicken value chain in Uganda and Burundi. Youth have invested along the chicken value chain as a feasible source of income and employment, however, many are discouraged due to limited output resulting from use of technologies that are not adapted to the ever-changing climate. They will strengthen existing multi-stakeholder innovation platforms use them to identify, co-learn and reprioritize climate resilient innovations for the chicken value chain. They will use a Resilient Innovation Plan Model (RIPM) to optimize and recommend resilient options for different scenarios for the targeted agro-ecological zones. They will produce translated audio-visuals about the prioritized climate resilient innovations, and use digital solutions at Farmers Service Centers to disseminate the information to rural communities
This study investigates the link between climate variations and the dynamics of antibiotic resistant bacteria (ARB) in maternity wards in Burkina Faso and Cameroon. By focusing on antibiotic-resistant pathogens such as ESBL-producing Escherichia coli, Klebsiella pneumoniae, and methicillin-resistant Staphylococcus aureus (MRSA), the research aims to mitigate their adverse effects on maternal and neonatal health.
Through comprehensive sampling, whole-genome sequencing, and analysis of environmental factors like temperature, humidity and airflow, the study will develop advanced models to predict future ARB dynamics under various climate scenarios. These predictions will inform targeted interventions, including enhanced hygiene practices, antibiotic stewardship, and environmental adjustments, in collaboration with healthcare professionals and local communities.
The project seeks to provide a comprehensive understanding of the relationship between climate change, drug-resistant bacterial dynamics, maternal and neonates health, leading to effective interventions and evidence-based recommendations for wider implementation.

South Africa
The World Health Organization is urging better tracking of fungal pathogens, which pose serious health risks to people with weakened immune systems, particularly in South Africa. Currently, there is a lack of understanding about how these infections occur and spread in at-risk communities, especially as climate change alters environmental conditions. Our project, supported by the Grand Challenges Africa initiative, aims to address this gap by developing a comprehensive system to monitor and study fungal pathogens in relation to environmental conditions. We plan to engage with local communities to learn how people are exposed to these fungi, especially through water.
We are designing a new tool to monitor river water for harmful fungi and will use the collected data to help public health officials better assess risks and protect communities. By collaborating with community groups, our research will directly support efforts to reduce the spread of harmful fungi, protect vulnerable populations, and adapt to the impacts of climate change on public health.

Moreover, the project team will facilitate networking, engagement and collaboration between stakeholders.
Vector-borne diseases (VBDs) like malaria and dengue pose significant public health challenges in Tanzania, exacerbated by climate change. Rising temperatures and unpredictable rainfall enable disease-carrying mosquitoes to thrive in new areas, putting vulnerable communities at greater risk. To tackle this growing threat, Dr. Devotha Nyambo of the Nelson Mandela African Institution of Science and Technology (NM-AIST) is leading a groundbreaking study that leverages artificial intelligence (AI) to enhance disease surveillance and prediction. However, for AI models to be truly effective, they must incorporate real-world data from the communities affected. Dr. Nyambo’s team will work with local populations in Morogoro, Manyara, and Dar es Salaam, engaging particularly with women, to gather on-the-ground data on mosquito breeding sites and disease cases. This community-driven approach will improve the accuracy of AI predictions and foster a robust early warning system for timely public health interventions.
Ultimately, this AI-powered initiative aims to enhance disease prediction, empower communities, and build resilience against climate-driven health threats. Dr Nyambo's vision of combining AI with community engagement could revolutionize the fight against VBDs in Tanzania and beyond.

An intelligent decision support for breeding future climate change resistant millet varieties in Senegal
An intelligent decision support for breeding future climate change resistant millet varieties in Senegal
Diariétou Sambakhe of the Regional Center of Excellence for dry cereals research (CERAAS) in Senegal will co-design an open-acces platform for knowledge sharing of annual ideotype maps of climate change resilient millet varieties in Senegal. The adaptation of crop varieties to their growing environment is the key factor supporting their performance. Regardless of genetic progress, the performance of major varieties still varies according to climatic conditions, crop management and pest pressure in the local environment. Knowledge of the interactions between variety traits, the environment and 'farmers' is needed to improve the performance of these varieties. They will redefine more precisely the millet growing areas in Senegal by considering the environmental conditions, crop management and pest pressure to predict their response to future climate conditions. They will identify better combinations of agro-morphological and genetic traits adapted to climate change. They will design an open access platform for knowledge sharing with stakeholders.

Research and Development of a Non-Hormonal Natural Product Based Female Contraceptive
Elizabeth V. M. Kigondu of the Center for Traditional Medicine & Drug Research (CTMDR), Kenya Medical Research Institute (KEMRI) is going to be exploring extracts and compounds from plants used traditionally in Kenya and reported to have a contraceptive effect, for further development of a non-hormonal natural product based female contraceptive. In some parts of Kenya, some communities use seeds or other plant parts as antifertility agents and some of these plants have been proven scientifically to have an antifertility effect in various animal models. In a small study carried out by Elizabeth’s team at KEMRI, they were able to demonstrate that one of our indigenous plants has an antifertility effect in mice. This study has formed the basis of the current project recently funded by the Gates Foundation, through the Science for Africa Foundation, where they plan to investigate the plant further, in addition to other selected plants, to establish the safety, the mechanism of action and identify the active components in the active extracts.

The project will mobilise communities to raise awareness of the need for environmental sanitation and mass trapping, a technique that has already proved promise and is suitable for insecticide-resistant outdoor Aedes in Kinshasa. The intervention will be evaluated based on a randomized controlled before and after study in two health zones of Kinshasa. A baseline serosurvey will be performed to document the prevalence of arbovirus risk in the community. Entomological and process-based indicators will be collected to assess the impact of the intervention.
The community-based approach aims to enable community groups to act as agents of change to minimize the effects of climate change on the health risk posed by Aedes mosquitoes. The approach aim to: (i) reduce larval habitats while breaking the cycle in which humans create a favourable environment for Aedes mosquitoes, (ii) increase community knowledge and skills in Aedes vector control, and (iii) to foster community ownership of Aedes vector control strategies.
The immediate expected result will be a diminished nuisance of Aedes and other mosquitoes in the selected communities, which will be the incentive for the target groups to continue the efforts and involve new participants.

Margaret Ilomuanya of the University of Lagos in Nigeria will develop a non-hormonal approach to contraception in women focussing on the interaction of mucoadhesive electrospun scaffold with cervical mucus. Studies have shown that unintended pregnancies occur due to perceived dissatisfaction, or unpalatable side effect profiles, arising frommodern hormonal contraceptive use. This has necessitated a need for more effective optionsin non-hormonal contraception to be made available to women. They will develop a novel blend of biodegradable electrospun scaffolds whose properties will be optimized using artificial neural networks aided surface response aided design to facilitate non-hormonal contraception via interaction with cervical mucus. They will evaluate the surface characteristics, mucoadhesive nature and safety of the developed scaffolds to demonstrate the potential of the developed electrospun scaffolds as a delivery platform for contraception.

The aim of Dr Sy’s project is to develop and improve mathematical and artificial intelligence (AI) models to estimate the impact of current and future climate change on the abundance, seasonal activity, vector capacity and population dynamics of Anopheles gambiae s.l.. These mosquitoes are mainly responsible for residual malaria transmission in northern and central Senegal. Climate change is thought to contribute to the persistence of residual malaria transmission in Senegal by supporting vector populations. To assess the risks associated with transmission, morbidity and mortality, it is necessary to combine biological models and climate scenarios using new technological approaches such as artificial intelligence and mathematical modelling.
By analysing data over two decades (2000 to 2023), it will be possible to adapt strategies and make predictions. The risks of a malaria epidemic can be identified at an early stage. This will ensure that the gains of the NMCP are not lost. It will also allow us to continue on the path towards the elimination of this disease, which is still possible in Senegal.

Enhancing Local Level Climate Adaptation Systems in Musanze District, Rwanda
GanzAfrica takes a systems level intervention to strengthen local adaptation capacities through a bottom-up, locally driven, multi-sectoral and youth centered approach. Climate adaptation initiatives in many countries are largely top-down, where decisions are made at central level due to limited local capacity of local actors. We deploy young adaptation champions in local departments of agriculture, land, and environment, to facilitate and coordinate adaptation initiatives. They will consult stakeholders and gather local perspectives, create inventories of data and evidence including documenting local knowledge and practices, setting up a demo plot to showcase adaptation practices, develop stakeholder collaboration and coordination frameworks, train local champions, set up community climate information, and community peer-learning systems. In the process, we create a platform for communities, sectors, and partners to collaborate, co-learn, co-create, test and co-implement evidence informed, context specific adaptation measures. Lessons drawn are harnessed to scale adaptation approaches and inform national policy.

Diversifying Gambian diets for health and Environmental Sustainability (DiGES)
Zakari Ali of the Medical Research Council Unit The Gambia at LSHTM in The Gambia will identify and promote the consumption and production of underutilized crops that are more resilient to climate change, reduce environmental impacts, and have positive health attributes. Studies have investigated different ways to produce enough food under climate change – with diverse evidence of success. This project will examine how populations can demand and consume foods that are more climate resilient. The project uses population diet as the entry point to agricultural adaption to climate change by identifying the barriers and opportunities for populations to demand and consume locally available and climate resilient foods. They will model different food system scenarios under climate change – engage food system stakeholders, policymakers and local farmers, and use social behaviour change communication (SBCC) strategies to promote the demand, consumption, and production of climate resilient crops.
