Problem Statement

The widespread presence of pharmaceutical products in Africa, such as antibiotics and other trace contaminants, has raised concerns about their adverse effects on public health and ecosystems. The ENZYREP project aims to develop large-scale use of enzymes as a nature-based solution to reduce micropollutants such as antibiotics in wastewater (e.g., hospitals, and pharmaceutical industries) as a means to limit the widespread presence of these harmful contaminants in the environment for the protection of public health and ecosystems.

Progress Highlights

Progress made includes, but not limited to, screening, extracting, purifying and characterizing two enzymes (laccase and tyrosinase) from African endogenous mushroom. Meanwhile, important capacity is being built in terms of training skilled research students and start-up a brand-new laboratory.

Key Findings

Both extracted enzymes can effectively remove drugs from wastewater. The treatment system can also be upscaled and optimized.

Potential Impact

ENZYREP project will shed light on the feasibility to effectively remove harmful contaminants from wastewater discharged from hospitals and pharmaceutical factories. Ultimately, a change in policy and regulations are expected to mandate polluters to implement treatment systems to deal with micropollutants before their discharge into nature.

Problem Statement

Since the 2000s, Aedes (Stegomyia) albopictus has become the dominant Stegomyia species in anthropogenic environments of Central-Africa, linked to dengue, chikungunya, and Zika outbreaks. Despite replacing native species, its bioecological drivers and genomic factors influencing its success and vector competence remain poorly understood. This project aims to elucidate these drivers.

Progress Highlights

We investigated Ae. albopictus ecological limits at two study sites, resulting in three published papers and the completion of four MSc programs. Key achievements include 3 lead author papers, 4 co-authored papers, and significant in progress in lab restoration and average in equipment acquisition.

Key Findings

We revealed that Ae. albopictus thrives in anthropogenic and forested areas, aided by human-altered microhabitats and natural ones like tree and rock holes. Its presence correlates with physicochemical features such as size, pH, redox potential, dissolved oxygen, and conductivity, showing a preference for larger, pH-neutral microhabitats.

Potential Impact

This project will allow characterization of Aedes albopictus relationship with native mosquito species sharing the same habitats and assess the arboviruses emergence risk. This will ultimately contribute effectively to the development of the arboviruses' control strategies in Gabon and inform preventive policies against zoonotic risks.

Madagascar

Problem Statement

Millions of farmers near high-biodiversity areas still depend on rainfed and low input farming practices such as shifting cultivation. These practices drive forest clearing and biodiversity loss and increase food insecurity and vulnerability to climate change. Climate-smart agriculture (CSA) aims to address these challenges, but its adoption remains low.

Progress Highlights

We implemented a randomised controlled trial (RCT) with members of village saving groups in south-eastern Madagascar to evaluate the impacts of cash and knowledge transfer (training in climate resilient farming practices and farm business school) on CSA adoption and local welfare. We recently conducted a baseline survey with 1300 households.

Key Findings

Communities are characterised by high levels of poverty and food insecurity. Livelihoods are mostly based on subsistence agriculture, with very limited adoption of climate-smart practices, and 37% of loans from village saving groups are used for food and emergencies. This leaves communities highly vulnerable to shocks.

Potential Impact

This project will provide evidence on what would best encourage the widespread adoption of CSA in Madagascar and ultimately pave the way for more resilient communities through increased knowledge and adoption of CSA, improved food security and welfare through increased and diversified income, while mitigating greenhouse gas emission.

As populations grow and natural environments become degraded in Africa, there is an increasing need for the recovery of nutrients from wastewater and other aqueous waste streams for agricultural use. This project tries to solve the issues related to surface water pollution by utilizing green fertilizer, which leads to water reclamation and recovery.

Progress Highlights

A qualitative and quantitative value of AWS in terms of nitrogen (N), phosphorous (P), and dissolved organic carbon (DOC) content is now known. The 100% of total suspended solids (TSS) were removed from AWS. The concentration of N, P, and DOC samples without suspended solids and turbidity was obtained.

Key Findings

Ultrafiltration separated DOC from nutrients at a rate of 95% at 5 bar. The permeate was fed to electrodialysis to separate/recover phosphorus and nitrogen. In the base and acid compartments, nitrogen and phosphorus were recovered at the rate of 90 % and 85% ammonium and phosphate at 30 V, respectively.

Potential Impact

Combining membrane filtration and bipolar electrodialysis is a good strategy for protecting the environment and producing green fertilizers. The process can be used to amend the soil or can be used in a balanced ratio of effluents by considering the needs of the plants and for a high yield.

Problem Statement

Few studies about genetic of neurodevelopmental disorders have been conducted in Sub-Saharan Africa and the genomic information underlying their mechanisms, especially in Rwanda, is still not adequately available. This study will focus on identification of genetic and environmental factors to better understand and mitigate the prevalence and impact of NDDs in the region.

Progress Highlights

The key activities accomplished under these project goals include Collecting blood and serum samples from 233 participants, extracting DNA from the blood samples of all participants, capacity building for PhD and master’s students and laboratory technicians (basic genomic skills, karyotype analysis), submitting one article for peer review, and holding collaborative monthly meetings among team members.

Key Findings

Whole exome sequencing (WES) of 18 patients with dysmorphic features and neurodevelopmental disorders (NDDs) was conducted. Thirteen pathogenic or likely pathogenic variants were identified in 13 patients, and variants of uncertain significance (VUS) were identified in 5 patients. For each case in the cohort, we compiled frontal photos, clinical features, and the disease-causing variants. The diagnostic yield of WES for dysmorphic features and NDDs was 72.2%.

Potential Impact

We conclude that the association of dysmorphic features and developmental delay in patients with neurodevelopmental disorders can predict the likelihood that whole exome sequencing (WES) will identify a causal variant of a phenotype. Therefore, systematic use of WES in NDDs will improve the diagnostic yield of rare diseases and enable better management.

Problem Statement

Schistosomiasis, the second most socio-economically devastating parasitic disease, affects 290 million people and causes 280,000 deaths annually in sub-Saharan Africa. Praziquantel, the only available treatment, doesn’t prevent re-infection or control egg-induced inflammation. Therefore, the development of effective therapeutic intervention strategies is urgently needed.

Progress Highlights

We examined the differential role of the regulatory T cell subset (Tregs) during acute and chronic murine schistosomiasis. Our data indicated gender-specific differences in susceptibility and Tregs gene expression, with females exhibiting higher susceptibility to the disease. Furthermore, we elucidated differential Treg subsets at different disease stages of the disease.

Key Findings

Our results indicated a gender-specific differential susceptibility to schistosomiasis infection that is likely driven by their differential Treg ability to control liver granuloma inflammation. Using state-of-the-art techniques (single-cell RNA and ATAC sequencing), we unprecedentedly elucidated the differential expansion of specific Treg cell subsets at each disease stage, revealing gender-specific regulatory mechanisms.

Potential Impact

This project has significant implications for the design of gender-specific prevention programs, treatment protocols, and vaccines. By unravelling the immunological mechanisms underpinning the observed gender disparity in susceptibility, the study will pave the way for devising effective therapeutic interventions that contribute to the well-being of populations beleaguered by schistosomiasis.

Problem Statement

Mental health knowledge in Africa is still low, whilst stigma and mistreatment towards people with mental health problems remain high, with no specific support for the youth. The MHLeC project aims to increase mental health literacy among young people in Malawi using university and community settings to improve overall knowledge and understanding of mental health among the masses.

Progress Highlights

Codesigned a mental health literacy e-curriculum that is deliverable online and in classroom settings. We have organized Malawi's first youth mental health festival, which will be running annually in October (Global Mental Health Month). We have engaged 5 tertiary institutions to deliver MHLeC within a feasibility trial.

Key Findings

University students who have completed the course so far have described their mental health learning experience as educative and interactive. They especially enjoyed videos in the course. They prefer the classroom-based delivery method. Average course satisfaction was 70% with all participants saying they would recommend MHLeC to their peers. A key challenge is not all tertiary institutions have equipment and resources to facilitate digital delivery.

Potential Impact

Preliminary conclusions so far are that the MHLeC is culturally relevant for university students and has potential to increase mental health literacy among youth en masse. The potential short term impact is real time mental health awareness raising. More long term impacts are a mental health education resource for national implementation with government support. This project will also inform evidence-based development of youth focused mental health policies for Malawi.

Problem Statement

The United Nations Environment Programme (UNEP, 2024) reported that 2.3 billion people are living in countries categorized as “water-stressed”. This water stress emanates from water scarcity or water being contaminated by toxic ions, drug metabolites, salinity, etc. The project seeks to develop water filtration materials (membranes) derived from biomass cellulose for use at household and community levels. The identified biomass are invasive plant species that are a menace to the environment, and elephant dung is waste from the high population of elephants found in Botswana, making cellulose a sustainable resource.

Progress Highlights

Cellulose was successfully extracted from elephant dung, honey mesquite, and sisal plants (invasive species) and characterized. It is currently being appropriately functionalized to impart metal ions, anions, quaternary ammonium compounds, and salinity removal abilities in preparation for membrane fabrication and testing.

Key Findings

Cellulose was chemically extracted from elephant dung, honey mesquite, and sisal leaf fibers. The amounts of cellulose extracted from honey mesquite and sisal leaf fibers were 37% and ≈50%, respectively. Elephant dung also furnished ≈50% cellulose. The results show that the 3 biomasses are good cellulose sources.

Potential Impact

Elephant dung, honey mesquite, and sisal leaf fibers are good sources of cellulose, which can be appropriately modified for various applications, replacing non-biodegradable synthetic polymer fibers. These biomasses are abundant and renewable, making them attractive as sustainable cellulose feedstocks. In our case, cellulose is used to develop materials for water filtration.

Problem Statement

East Coast fever (ECF) is a devastating tick-borne disease that affects cattle productivity in sub–Saharan Africa. Currently, there is only one ECF vaccine, yet the vaccinated cattle revert to ECF pathogen reservoirs, hence promoting re-transmission. The project research is aimed at developing alternative vaccines to interfere with ECF pathogen development and transmission in ticks and/or cattle.

Progress Highlights

We are pursuing the development of live attenuated vaccines and subunit/ recombinant protein-based vaccines. We have aligned the lab for vaccine research. We are now performing cell culture studies assessing the potential of 3 DNA alkylating to induce ECF pathogen mutation. We have embarked on examining the diversity of ECF pathogens.

Key Findings

So far, Drug A has shown the potential to affect ECF-pathogen growth under culture. The drug-treated ECF pathogen has shown slow replication, suggesting that the drug could have altered the pathogen's genetic makeup, weakening it. Comparisons with the other two drugs are still to be made.

Potential Impact

This research aims to develop recombinant protein-based vaccines with the potential to block ECF-pathogen development and/or transmission in ticks.

Problem Statement

To date, there is no vaccine effective enough to counter the deadly burden of malaria. This project provides early in-depth assessment of the functional impact of the parasites’ genetic diversity and seeks to decipher its functional contribution in the effectiveness of potential malaria vaccine candidates.

Progress Highlights

Our preliminary reveal a high level of efficacy of vaccine-induced monoclonal antibodies to blood-stage malaria vaccines candidates on the highly genetically diverse parasite populations circulation in malaria endemic settings in Senegal. These data further warrant the importance of such parasite antigens as lead malaria vaccines.

Key Findings

So far, our data on the blood-stage antigens of the PfRH5 complex are high promising. These data complement earlier reports on the strain transcendent potential of monoclonal antibodies to the PfRH5 complex, in the more diverse and complex parasites populations in malaria-endemic settings; therefore, sparking current vaccine development strategies targeting this complex.

Potential Impact

Findings from this study will be highly relevant in developing the next generation of blood-stage malaria vaccines, as it aims to provide compelling evidence of the functional relationship between genetic diversity and the susceptibility of P. falciparum clinical isolates to vaccine-induced monoclonal antibodies targeting members of the PfRH5-complex.

Problem Statement

A large population of African countries suffers from digital exclusion. The main reason for the digital gap is the low telecommunications investments in areas with very low population income. Therefore, it is important to study novel and practical telecommunication solutions adapted to underprivileged regions at low costs. In this context, our research project will answer the question: how to provide Internet access to unconnected and under-connected regions quickly and with reduced costs.

Progress Highlights

So far, we have studied the use of drones and low-orbit satellites to provide connectivity to users in remote areas. We proposed efficient approaches to optimizing drones' trajectory, improving their energy efficiency, and prolonging their battery life. We also proposed mechanisms to quickly connect users in remote areas to spatial networks.

Key Findings

Within the framework of this project, we proposed algorithms with low complexity that can be implemented on drones with low computational power. We also proposed efficient mechanisms to implement our algorithms in a distributed and asynchronous way, which is important to ensure distributed coordination between the network agents

Potential Impact

This project has raised awareness among industrials about the importance of using non-terrestrial networks to provide rapid connectivity to the populations in unconnected areas. It has also resulted in many useful ideas where drones can be used in post-disaster scenarios to replace the damaged infrastructure and to support the terrestrial network during temporary events (such as festivals and sportive events).

Problem Statement

While Central Africa contains the second-largest continuous block of tropical forests after the Amazonian basin, it is expected to lose 41% of its forest cover by 2050. Human disturbances are increasingly being in tropical forests, threatening their biodiversity and the goods and services that benefit human well-being. Dr. Loubota Panzou’s research evaluates whether changes in biodiversity, ecosystem functions, and services will vary by type of disturbance and whether these changes alter trajectories of degradation and/or recovery and resilience to disturbance in Central Africa.

Progress Highlights

Six ongoing fieldworks in two forest allocations (undisturbed forest and selectively logged forests), Installation of 1-ha permanent plots, Tree measurements (diameter, height, and crown dimensions), diverse interviews and field surveys, and Installation of camera traps in the permanent plots.

Key Findings

About 30 permanent plots of 1ha were set up in undisturbed and selectively logged forests. Trees with diameters ≥10cm were identified and measured with reference standards. To date, 7078 trees have been inventoried with their diameter measurement, and 3246 of 7078 trees were selected for height and crown measurements.

Potential Impact

The project has major scientific and societal implications because it will enhance national culture for future African generations. It will strengthen knowledge and skills in multiple disciplines and approaches to forest ecology. The knowledge acquired will be made available to universities and research institutions to build science capacities.

Problem Statement

Malaria continues to be a public health problem in Africa, contributing to the high rates of morbidity and deaths. Prof. Dr. Sacomboio's research assesses whether certain blood groups are associated with malaria infection susceptibility and severity.

Progress Highlights

The first phase of the project has been completed. This included monitoring patients with malaria, where more than a thousand patients were monitored, and 2 scientific articles have been published.

Key Findings

It is imperative to differentiate patients with malaria based on blood groups and sickle cell trait, taking into account mainly the blood count parameters that demonstrate that there are patients who, depending on blood group or sickle cell trait, may react weakly to malaria infection regardless of the degree of parasitemia and medical prognosis.

Potential Impact

This research will identify phenomena that may be associated with resistance to treatment, create public policies and improve human health.

We are building human capacity by training two undergraduate students, two masters’ students, and two doctorate students.

Key Findings

Porous carbons with high adsorption capability for the removal of organic contaminants in waste water were produced from polyethylene terephthalate plastic waste. Multiwalled carbon nanotubes have been effectively produced from polypropylene terephthalate waste and polypropylene waste collected from the Dandora dumping site in Kenya.

Potential Impact

The effective synthesis of porous carbons and multiwalled carbon nanotubes from plastic waste offers a less expensive and more ecological alternative for repurposing of plastic waste. The adsorption characteristics of porous carbons for the elimination of organic contaminants in water may help achieve clean water and sanitation.

Problem Statement

Bananas and plantains, key staples in tropical Africa, are perennial plants generating significant waste, typically used as fertilizers or animal feed. This project aims to repurpose banana plant waste through green nanoengineering to create products for microbial infection control, including surface sanitizers, water treatment, and antimicrobial drugs, enhancing wound healing.

Progress Highlights

The progress so far includes testing of biogenic nanoparticles from bananas, Isolation of antimicrobial secondary metabolites from banana wastes, Identification of plant metabolites, and standardization of the quality attributes of biogenic nanoparticles. We have also used raw banana saponins for nanoencapsulation of antimicrobial agents.

Key Findings

Green nanotechnology from bananas isolated bioactive metabolites has shown superior antimicrobial/wound healing properties compared to plant extracts/AgNPs. Banana crude saponins formed nano-micelles with better encapsulation efficiency (55%) for hydrophobic phthalocyanine than pure saponin (33%). Nanoengineered bananas produced magnetic and porous nanoparticles with great potential for water purification.

Potential Impact

Green nanotechnology is revolutionizing medicine and environmental management by converting banana waste into potent solutions for infection control and wound healing. This innovative approach not only promotes the sustainable use of natural resources but also pioneers the development of advanced materials for crucial tasks like surface cleaning and water purification.

Problem Statement

Despite the continuous health burden of Tuberculosis in Africa, there is almost no literature on the Tuberculosis experiences of Adolescents and Young People [AYP] or how best to offer tuberculosis services to this group, which is at the highest risk. The OASIS-PN project fills this critical gap by working with AYP to understand their experiences and co-develop mechanisms and strategies to optimize TB services using a person-centred approach.

Progress Highlights

Established inter-institutional collaboration agreements, taken leading roles in 4 key consortia, published 57 manuscripts, enrolled 11 PhD (4 directly supported) and 5 MSc students (1 completed), and created 5 jobs.

Key Findings

For the first time in Africa, socio-behavioural science is being embedded in the building of a research site for TB clinical, epidemiological, and intervention research. We now understand the kinship structures and co-habitation patterns of families affected by drug resistant tuberculosis in Namibia, as well as the TB care preferences of children / adolescents and young adults.

Potential Impact

Tuberculosis services for adolescents and young adults have multiple challenges and improving them an urgent priority. The OASIS-PN project will provide much-needed practical evidence of what solutions are preferred and how these may be optimally implemented, in collaboration with affected communities.

Problem Statement

Digital health interventions can potentially address some of Africa's healthcare delivery challenges. However, lack of evidence of their efficacy, cost-effectiveness and improved health outcomes has hampered their integration into health systems. The project aims to implement a 5G digital health testbed for generating such evidence for novel digital health interventions.

Progress Highlights

A working 5G testbed prototype based on open-source software, off-the-shelf mobile network devices, and a working virtual clinic system prototype have been developed. Three master's students have graduated, and additional funding of about $ 100,000 USD has been received due to the impact of this project. Several local and international conference papers were presented, 1 journal paper was published, and one book chapter was in print. An industry partner has indicated interest in adopting the virtual clinic system and will provide additional funding for implementing a real-world 5G test infrastructure based on the developed prototype.

Key Findings

Evidence for teleaudiology has been established. Plans for implementing a real-world 5G test network are underway. An industry partner has expressed interest in purchasing the virtual clinic system (VCS). There is significant interest in using the VCS for telesurgery, mental health, and other specialist medical services.

Potential Impact

This project will apply novel concepts to develop a secured real-world 5G digital health testbed to provide a platform for testing and evaluating commercially available mHealth applications and medical devices originally designed for in-person care. The expected impact of the project is the accelerated translation of research results into practical interventions that can help strengthen Africa healthcare system.

Problem Statement

Recent large-scale climate shocks in Africa and other continents have highlighted how biodiversity loss, climate change, urbanization, and structural inequality are converging to threaten planetary health. The escalation of urbanization contributes significantly to the urban heat island effect, air pollution, water contamination, flood risk, coastal erosion, and flood risk. Concurrently, disparities in access to quality green space are exacerbated between affluent and impoverished neighborhoods. However, we lack impact assessments of urban green infrastructure and climate adaptation that consider multiple hazards and employ transdisciplinary approaches. Working in Namibia, Madagascar, and Sierra Leone, this research aims to evaluate the effectiveness of green infrastructure innovations in informal and peri-urban areas for disaster risk reduction in peri-urban areas, now and in the future.

Progress Highlights

We have published ten peer-reviewed articles, one special issue, two book chapters, and one conference poster. In addition, we have presented our work at 19 invited talks, including five keynote presentations. Our project consists of six PhD students. We have completed two field seasons in Madagascar, one in Sierra Leone, and one in Namibia. Included are the organization of eight workshops, conference sessions, and two training sessions. We have also published two animations and one podcast.

Key Findings

There are significant disparities in green space inequities in Africa. There is a need to improve transportation networks, allowing residents easy access to nature. The height of buildings influences urban outdoor thermal comfort and retrofitting urban structures with green infrastructure. Local authorities should link diverse demographic groups (by age, race, education, and occupation) to heat management in areas of thermal stress and enhance transparency, accountability, and participation in decision-making. Future visions of informal settlements include greater access to green space and more integrated land use planning.

Potential Impact

We have already seen an impact through input into policy processes. For instance, we have given inputs in five policy reports, including the IPCC WG II mountains and human settlements chapter, the AU Climate Change Strategy, and the UN Food and Agricultural Organisation Urban Forestry report. Our research aims to advance theoretical understandings in transdisciplinary practice and co-production. In addition, we aim to enhance knowledge and methodological approaches so that researchers and urban planners can further optimize green infrastructure strategies towards creating cooler and greener urban environments using the smallest space to enhance the best cooling effect.

Niger

Problem Statement

In Niger, despite tremendous efforts made to prevent/alleviate the prevalence of infant and child malnutrition, the statistics still show alarming thresholds. Recurrent episodes of food insecurity affect infants in a critical period of food transition that eventually puts them at risk of adulthood onset of chronic diseases. This underscores the need for more operational studies to explore the implementation of local solutions for producing therapeutic flours for managing malnutrition.

Progress Highlights

Some of the achievements of the project so far include the creation of a multinational (Africa and Europe), multisector, and multidisciplinary team, recruitment of 1 researcher, full funding of 2 PhD students and 4 Master students, creation of new research axes in almost all the institutions and acquisition of new technologies to the benefit of institutions.

Key Findings

A community-specific qualitative design was conducted through in-depth, semi-structured interviews of focus group discussions and with key informants and participants from three regions of Niger. The study concluded with typical core food and supplementary ingredients across the investigated localities. However, the difference in the culinary/ transformation habits creates disparities in the nutritional value of the cooked foods, making some more beneficial than others.

Potential Impact

The project promotes a dynamic multidisciplinary team that participates in the development of new research axes in the partner institutions, allows for the acquisition of/access to new technologies, and forms young, growing scientists fully funded in the project’s implementation, targeting local solutions for a significant and quasi-permanent public health issue.

Problem Statement

Artisanal Gold Mining (AGM) is practiced by 5-6M people in Africa. In full expansion, AGM suffers from practices based on the absence of planning, the use of rudimentary tools and the uncontrolled use of toxic chemicals. There is no quantitative data on the impact on the environment due to AGM. This research will provide artisanal miners with essential practical basis for better management of mining techniques, identify and prevent the risks involved in artisanal gold mining while ensuring environmentally sustainable development.

Progress Highlights

In Guinea and Mali, the team carried out: Identification of gold panning techniques and technologies in place on sites, understanding the perception of local communities and gold miners on the impacts of gold panning on the environment, and the main causes of landslides; and collection of samples (sediments, soil and water)

Key Findings

This research shows that gold is mined in an artisanal manner using chemicals products that are dangerous for human and environmental health. Also, it shows that landslides are mainly due to the human factor (behavior of actors and lack of regulation of the sector taking into account safety).

Potential Impact

The knowledge gained from this research will be transferred to public authorities, communities, and gold miners to minimize the risk of accidents, particularly landslides on gold panning sites; to improve the management of AGM and should ultimately provide solutions to promote smoother gold mining, with less impact on the environment.

Problem Statement

Earthquakes are among the most dangerous natural disasters, resulting in significant economic and human losses, primarily due to destroyed buildings, bridges, and other infrastructure. While Madagascar mostly experiences small to moderate earthquakes, recent events such as those in Famoizankova (1991) and Betafo (2017) have caused damage near the epicenters. Therefore, the EARTHMOVING initiative aims to enhance earthquake research in Madagascar, specifically through improving earthquake preparedness and automating earthquake detection to minimize the impact of potential future earthquakes

Progress Highlights

We have developed a machine-learning-based earthquake monitoring system, which allows us to classify the nature of seismic events. This system also includes a mobile phone application that provides timely information to the community and relevant risk agencies. In addition, we have worked to understand the site effects in Madagascar. Additionally, to gain insights into the current deformation in Madagascar, we use a technique called INSAR and develop a database of the country's velocity field.

Key Findings

We have recently developed an earthquake monitoring system that can distinguish between anthropogenic and natural earthquakes. In addition, we have created a mobile application that can alert and inform citizens in case of an earthquake, and collect their experiences through comments, pictures, and videos in the aftermath. Furthermore, using the spectral decomposition approach, we have evaluated the source stress drop, site effects, and attenuation, which are vital for developing the ground motion model for Madagascar. Our research has also revealed that the surface displacement in Madagascar is influenced not only by tectonic factors but also by sedimentary dynamics such as erosion and sedimentary deposits.

Potential Impact

The new earthquake monitoring system has important implications for mining control and improving seismic hazard management. This system includes a mobile application that provides timely earthquake information to the community and risk management agency. The database of surface displacement is a crucial source of data for various multidisciplinary topics. It provides information about tectonics and highlights sediment dynamics in different regions of Madagascar.

African countries continue to face shortages of vegetables and fruits, leading to high importation. To reduce this importation, intensified domestic production is essential to cushion fruit and vegetable prices during the post-COVID-19 pandemic. This project addresses the high costs of high-value vegetable crops incurred by small-scale agripreneurs. It also focuses on contributing to the availability of orange-fleshed sweet potatoes in the Kingdom of Eswatini. Plant tissue culture is used as a tool to address the problems mentioned above.

Progress Highlights

The project has trained 2 master’s and 2 PhD students on plant tissue culture. The plant biotechnology research laboratory has been renovated, upgraded, and equipped. Technological Tunnel has been constructed for research and 2 new master students have been recruited for training on plant tissue culture.

Key Findings

Micropropagation of pepper and orange-fleshed sweet potatoes has been responsive to a formulated plant-growing medium developed using agro-waste from Rhodes Food Group in Eswatini.

Potential Impact

This project will produce competent postgraduates in Horticulture hired by biotechnology companies outside the Kingdom of Eswatini. It also aims to promote the commercialization of agro waste from Rhodes Food Group as a plant-growing medium. Through the project, the Eswatini population will adopt orange-fleshed sweet potatoes.

Problem Statement

Globally, oyster populations have declined due to changing climate and other human-induced pressures such as pollution, habitat degradation, and over-harvesting. Along the coast of West Africa, oysters play various functions, from serving as ecosystem engineers to improving water quality to supporting the livelihood of coastal populations. Unfortunately, the once vibrant oyster fishery along the West African coast has been declining in line with global shifts, with local pressures exacerbating the problem. Our project seeks to understand how oyster environments along West Africa have changed historically, how these changes impact their ability to grow and reproduce and provide answers for rebuilding lost populations in a resilient and sustainable way.

Progress Highlights

The project has so far collected data on O-18 and C-13 on fossilized shells along the West African Coast, collected Mg/Ca data on live shells, and acquired an Isotope Ratio Mass Spectrometer, which is being used for stable isotopic measurements of water and live shells.

Key Findings

Temperature and salinity reconstructions from fossilized shells show remarkable changes in oyster environmental conditions. Temperatures in estuaries where oysters live have increased significantly through time while salinity regime have decreased significantly through time. Present day water and shell measurements depict mostly freshwater conditions in the Anyanui Creek with Mg/Ca ratios in the oyster shells depicting compromised shell building capabilities of the oysters..

Potential Impact

With the data gathered so far, it apparent that the West African Mangrove Oyster has become very vulnerable to climate change. This vulnerability is also exacerbated by local pressures especially pollution and habitat destruction. The findings of the project will shape our understanding of the how climate change threatens this important fishery and provide insight into charting a sustainable future for oysters along the Coast of West Africa.
