As the risk of floodwaters rise each rainy season, the people of Kano, Nigeria, face a battle against nature that feels more urgent each year. But there is hope at last, a project at Bayero University, under the vision of Prof Aliyu Salisu Barau, is changing the game. Through the PASET Regional Scholarship and Innovation Fund (Rsif), this initiative by Prof Barau and his team is teaching communities to tackle flood risks head-on with Do-It-Yourself (DIY) adaptation strategies. Bayero University is one of the15 Rsif African Host Universities (AHU), focusing on climate change. This approach empowers the community to develop their own flood risk communication methods, equipping them to face the mounting impacts of climate change with resilience and resourcefulness.
Attending COP 29 this week with his team, Prof Barau is at the fore front sharing the successes and lessons of this initiative, showcasing Nigeria’s community-driven approach to resilience on the world stage. This is a significant step in climate change adaptation strategies.
We caught up with Prof Barua and had this conversation:
Q: What motivated you to initiate the “Do-It-Yourself Adaptation” project, and what specific challenges does it aim to address in Northern Nigeria?
A: People in every community have inherent and inherited strategies to cope with a wide range of issues based on their nature of environment. On this note, our project explored some of the local knowledge
systems and experiences that could help in promoting and integrating them in addressing flood risks. These knowledge systems are key motivations and also the inherent failures associated with government-driven flood mitigation interventions that have failed to support affected communities.
Q: Can you describe the main goals of the project and how they align with the needs of rural communities facing climate risks?
A: The main goals are to promote communication strategies that demystify the science of climate change and flood adaptation in such ways that such knowledge will be available to people in their local language and regardless of their level of literacy.
Q:Could you explain the key features of the flood risk hazards toolkit and how it will empower communities to adapt to climate change?
A: Loss of shelter and farm produce are critical forms of loss and damage for rural communities. However, development of knowledge streams of how to promote resilience through cartoons, stage dramas and songs, a flood messaging app, that specifically educates communities on pre-disaster, during, and post-disaster scenarios.
Q: What immediate benefits do you anticipate for communities involved in this project, and how will you measure its success?
A: The use of smart technologies is an important and easy way for communities to share flood risk information easily and immediately, which is very important. Similarly, the cartoons and songs are tool for easily reaching out to women and youths in
particular through these tools’ entertainment dimensions.
Q: How does this project fit into Nigeria’s broader climate adaptation strategies and its commitments under international agreements?
A: African countries and Nigeria inclusive at the moment need to give top priority to community-focused adaptation education, information sharing and engagement as best ways to achieve adaptation and climate resilience from the grassroots.
Q: What specific messages or outcomes do you hope to bring to COP 29 regarding community-led adaptation efforts?
A: African needs more creative ways to enhance, upgrade and improve climate resilience and adaptation strategies that include local knowledge systems and experiences.
Q: In what ways do you believe grassroots initiatives like yours can influence national and international climate policies moving forward?
A: This kind of effort must start from somewhere. We are glad to be among the set of researchers to push this forward.
Q: What final thoughts would you like to share about the importance of community engagement in addressing climate change at COP 29 and beyond?
A: Rounds of COP are for the privileged and messages of communities are expressed through intermediaries. However, community engagement is a vehicle that takes communities through COPs meetings through verifiable results of what communities can do on their own to achieve resilience and positive climate actions.
As world leaders and experts gather at COP29 to address climate resilience and adaptation, we shine a spotlight on Dr Fenet Belay, a Regional Scholarship and Innovation Fund (RSIF) scholar, from Ethiopia. Rsif is the flagship programme of the Partnership for Skills in Applied Sciences, Engineering, and Technology (PASET), managed by the International Centre of Insect Physiology and Ecology (icipe) as the Regional Coordination Unit. Dr Belay focuses on the critical struggles faced by smallholder farmers in Southwest and Central Ethiopia. Her work reveals how the extreme Coefficient of Variability (CV) in rainfall in Central Ethiopia severely hinders these farmers’ ability to adapt to climate shifts. Rainfall unpredictability in this region disrupts crop yields and food security, illustrating the urgency of climate solutions that support the world’s most vulnerable agricultural communities. Dr Belay’s findings underscore the pressing need for resilientstrategies tailored to smallholder farmers, a theme at the forefront of this year’s COP agenda.
We sat down for an interview with Dr Balay recently:
Q: In light of COP29’s focus on climate resilience, how do your findings from Southwestern and Central Ethiopia illustrate the specific adaptation challenges faced by smallholder farmers, and what practical, scalable solutions have emerged from your research that could be spotlighted at COP29 to support climate adaptation across similar regions?
A: My findings from Southwestern and Central Ethiopia reveal a nuanced picture of the adaptation challenges smallholder farmers face, and they identify practical, scalable solutions that align well with COP29’s focus on climate resilience. Here’s how my research can inform global discussions on supporting climate adaptation for smallholders in similar regions:
Climate Variability and Water Stress: The data show significant rainfall and temperature variability, with regions like Tututi experiencing pronounced rainfall instability. This variability creates severe water stress, making farming less predictable and threatening food security. Scalable solution: Community-managed water harvesting and small-scale irrigation systems are practical interventions that can be adapted to other water-scarce, rain-dependent regions. Highlighting these systems at COP29 could illustrate how low-cost, localized water management approaches help farmers buffer against climate unpredictability.
Vulnerability Disparities by Agroecology: The finding that lowland farmers have higher vulnerability indexes than those in midland or highland zones underscores the need for tailored adaptation strategies based on agroecological context. Scalable solution: Promoting agroecology-specific adaptation measures—such as drought-resistant crops for lowland zones and soil conservation techniques for highlands—can help optimize resilience efforts across diverse landscapes. This approach could serve as a model at COP29 for customizing adaptation policies based on specific climate and topographical conditions.
Socioeconomic Barriers to Adaptation: Factors such as limited access to agricultural credit, lack of market access, and gaps in climate information significantly affect adaptation choices. These socioeconomic constraints are common among smallholders globally. Scalable solution: Expanding rural credit systems and mobile-based climate information services can bridge these barriers, providing farmers with the resources and knowledge needed to make informed adaptation choices. These scalable solutions could be highlighted at COP29 to showcase how addressing socioeconomic barriers supports resilience at the grassroots level.
High-Impact Adaptation Strategies: My research identifies improved crop varieties, irrigation technology, and crop diversification as highly effective strategies, significantly enhancing food security. Farmers who adopt these practices demonstrate notable caloric improvements, underscoring their effectiveness. Scalable solution: Encouraging the comprehensive adoption of these high-impact practices—through subsidies, extension services, and knowledge-sharing networks—can make adaptation more accessible and impactful. Spotlighting these strategies at COP29 could advocate for policies that encourage diverse, integrated adaptation approaches rather than one-size-fits-all solutions.
Data-Driven Policy Support: The use of statistical models like the Multivariate Probit and Multinomial Endogenous Switching Regression models provides robust evidence for the impact of adaptation on food security. Scalable solution: Promoting data-driven decision-making and incorporating similar analyses into policy design could improve the effectiveness of climate adaptation programs globally. COP29 could benefit from these insights, advocating for policies grounded in rigorous, context-specific research.
My findings highlight practical, evidence-based solutions that address both immediate needs and long-term resilience, making a compelling case for policies that empower smallholder farmers with the tools and resources to adapt sustainably. Presenting these insights at COP29 would support the global agenda for building resilient food systems across vulnerable regions.
This evidence strongly supports advocating for policies that promote comprehensive adaptation strategies rather than isolated interventions, which could be a powerful message for COP29 discussions on food security. By showcasing these findings at COP29, my study not only underscores the adaptive capacity of smallholders in SSA but also provides practical, scalable strategies and policy recommendations that could influence global and regional climate resilience initiatives.
Q: In your view, how can innovations driven by African agribusiness leaders and researchers contribute to more resilient food systems, particularly in the context of Ethiopia’s rapidly changing climate?
A: Innovations driven by African agribusiness leaders and researchers can play a crucial role in creating more resilient food systems in Ethiopia, especially in the face of a rapidly changing climate. First, the development of climate-resilient crop varieties through research can significantly enhance productivity and food security. These varieties can withstand extreme weather conditions, pests, and diseases, ensuring stable yields even under stress. Secondly, agribusiness leaders and researchers can foster the adoption of sustainable farming practices, such as agro-ecology and regenerative agriculture. By promoting techniques that enhance soil health, water conservation, and biodiversity, these practices can improve resilience to climate impacts while also increasing farmers’ profitability.
Innovations such as precision agriculture, mobile apps for market access, and climate-smart farming tools can provide farmers with real-time data and insights. This empowers them to make informed decisions regarding planting times, resource allocation, and risk management. Collaboration between agribusiness, research institutions, and local communities is essential. By engaging farmers in the innovation process and incorporating indigenous knowledge, solutions can be tailored to local contexts, ensuring greater acceptance and effectiveness. Furthermore, enhancing access to financial services, such as microcredit and insurance products, can enable farmers to invest on innovative practices and technologies. Financial services motivate smallholder farmers to adopt new methods and mitigate risks associated with climate variability.
In summary, climate-resilient crops, improved agricultural technology adoption, improved extension services, improved access to financial services significantly contribute to building more resilient food systems in Ethiopia, addressing both current challenges and future climate uncertainties.
Q: What role does climate-smart agriculture play in enhancing the food security and resilience of smallholder farmers, and can you share any success stories from your work that illustrate this?
A: Climate-smart agriculture (CSA) plays a vital role in enhancing food security and resilience among smallholder farmers by promoting practices that improve productivity while adapting to and mitigating the impacts of climate change. CSA focuses on three key objectives: increasing agricultural productivity, enhancing resilience to climate variability, and reducing greenhouse gas emissions.
For smallholder farmers, implementing CSA practices such as crop diversification, soil health management, and efficient water use can lead to improved yields and stable food supply. For example, integrating drought-resistant crop varieties can help farmers maintain production levels during periods of low rainfall. Additionally, practices like agroforestry can enhance soil quality and biodiversity, further increasing resilience to climate shocks.
In my research, one success story emerged from a group of farmers in Central Ethiopia who adopted a combination of improved crop varieties, irrigation technologies and crop diversification. By implementing these climate-smart practices, they reported a substantial increase in their yields, even during periods of erratic rainfall. These groups of farmers not only improved their food security but also gained better market access, as they were able to sell surplus produce. Their experiences highlighted how targeted support and training in CSA practices can lead to significant improvements in resilience and economic stability.
Furthermore, community-based initiatives that promote collective action and knowledge sharing among farmers have proven effective resilience and adaptive capacity of smallholder farmers. In one case, a collective action of farmers implemented a crop rotation system using diverse crops, which not only enhanced their resilience to pests and diseases but also increased overall community food security.

Q: When it comes to building resilient food systems, what lessons can other African countries learn from the adaptive strategies of smallholder farmers in Ethiopia?
A: There are several valuable lessons that other African countries can learn from the adaptive strategies of smallholder farmers in Ethiopia. First, crop diversification has proven effective in enhancing food security and resilience by mitigating risks associated with climate variability and market fluctuations. The adoption of climate-smart agricultural practices, such as improved seed varieties and efficient irrigation, can significantly boost productivity while adapting to changing conditions. Community collaboration, exemplified by cooperative farming and knowledge-sharing initiatives, strengthens ties and facilitates access to resources. Moreover, utilizing mobile technology for disseminating weather forecasts and market information empowers farmers to make informed decisions. Strengthening agricultural extension services is also crucial for educating farmers about new practices, while access to microcredit and crop insurance can enable investments in resilience. Finally, supportive government policies that prioritize research, technology transfer, and farmer education can tailor interventions to local contexts. Therefore, other African countries can enhance their food security and resilience in the face of climate change and other disruptions embracing theses strategies.
Q: How has the support from Rsif contributed to your research, and in what ways can programmes like Rsif be scaled up to foster greater innovation in Africa’s agricultural sector?
A: The support from Rsif has been instrumental in my research on climate change adaptation strategies for smallholder farmers in Ethiopia. Rsif provided essential funding for data collection, access to research facilities, and networking opportunities with other researchers and agricultural experts, enabling comprehensive fieldwork and engagement with local communities. To foster greater innovation in Africa’s agricultural sector, programs like Rsif can be scaled up by increasing funding for research initiatives, establishing collaborative networks between universities, research institutions, and local agricultural organizations, and implementing capacity-building training programmes focused on emerging technologies in agriculture. By enhancing these aspects, Rsif can play a pivotal role in transforming Africa’s agriculture and ensuring smallholder farmers’ food security.

Q: What are the key barriers you’ve identified that hinder smallholder farmers from implementing climate-resilient practices, and how can they be overcome through research and policy?
A: There are various factors that significantly influence farmers’ decisions to choose and implement adaptation strategies in the face of changing climatic conditions. Key among these factors is the agricultural extension services, which provide farmers with critical information on best practices and new technologies; those receiving regular support are more likely to make informed decisions that enhance their resilience to climate change. Additionally, the educational level of farmers plays a significant role in their ability to understand and respond to climate-related challenges, with higher education often correlating to improved comprehension of scientific information and technology. The size of a farmer’s land holding also impacts their capacity to implement adaptation strategies, as larger holdings offer more opportunities for diversification and investment in sustainable practices. Timely access to relevant climate information is essential, enabling farmers to anticipate and respond to changing conditions, while access to agricultural credit allows them to invest in necessary resources for adaptation. Furthermore, proximity to markets influences farmers’ ability to sell their products and reinvest in their operations; those closer to markets can more easily access resources and information, facilitating the adoption of adaptation strategies. Overall, understanding these influences is essential for policymakers and agricultural support organizations aiming to enhance the resilience of farming communities against climate change. Addressing these factors such as improving access to agricultural extension services, implementing educational programmes (farmers training), facilitating access to credit, improving market accessibility, and ensuring timely dissemination of climate information can significantly enhance farmers’ resilience and food security.
To overcome these barriers, targeted research can play a vital role in identifying effective and context specific adaptation strategies that are feasible for smallholder farmers. Policy interventions should focus on enhancing access to climate information through the development of localized weather forecasting systems and the establishment of information sharing platforms. Strengthening agricultural extension services by training more extension workers and ensuring they are equipped with up-to-date knowledge on climate resilience can provide essential support to farmers.
Q: Looking ahead, what innovations do you believe hold the greatest potential for building resilient food systems in Africa, and how can African researchers and agribusiness leaders work together to make this a reality?
A: Looking ahead, several innovations hold significant potential for building resilient food systems in Africa. First, climate change adaptation strategies, such as improved crop varieties, irrigation technologies and crop diversification can enhance productivity while reducing environmental impact. Second, the development and dissemination of drought-resistant crop varieties can help mitigate the effects of climate variability. Additionally, the use of digital technology, including mobile applications for weather forecasting and market access, can empower farmers with timely information and resources. To make these innovations a reality, collaboration between African researchers and agribusiness leaders is crucial. Researchers can focus on generating evidence-based findings and developing new technologies tailored to local contexts. Agribusiness leaders, on the other hand, can leverage their market knowledge and networks to facilitate the adoption of these innovations. Joint initiatives, such as public-private partnerships, can provide platforms for knowledge exchange and resource mobilization.
Moreover, creating innovation hubs that bring together researchers, entrepreneurs, and farmers can foster collaboration and drive local solutions. By aligning research agendas with the needs of the agricultural sector and ensuring that innovations are accessible and scalable, we can build resilient food systems that enhance food security and support sustainable development across Africa.
As the world gathers for COP29, we want to highlight the work of Rehema Mrutu, a Regional Scholarship and Innovation Fund (Rsif) scholar, recognized at COP28 in Dubai last year for her research contributions to a sustainable future.
Rehema is a Tanzanian national pursuing a PhD in Natural Resource Management and Climate Change at the Centre of Dryland Agriculture at Bayero University Kano, Nigeria with research placement at Worcester Polytechnic Institute in USA. Rsif is the flagship programme of the Partnership for Skills in Applied Sciences, Engineering, and Technology (PASET), an Africa-led, World Bank-affiliated initiative, managed by the International Centre of Insect Physiology and Ecology (icipe) as the Regional Coordination Unit. With COP29 upon us, the world looks to build on environmental successes, such as the remarkable recovery of the ozone layer, showing that unified global action can bring real change.
We recently spoke with Rehema about her research and its connection to ozone layer protection—a topic that’s also high on the COP29 agenda:
Q: Can you share your journey and what inspired you to focus on climate change research, particularly in relation to the ozone layer? How has your background shaped your work on these crucial environmental issues?
A: I come from a cow farming family. And I have always been fascinated by any idea that boosted productivity because productive cows paid for my school fees. After my first degree at the University of Dar es Salaam, I pursued research on antimicrobial resistant bacteria in cows at the Nelson Mandela African Institution of Science and Technology (NM-AIST), as a master’s student in Biomedical Engineering. This led to publications that I later presented in a livestock conference. It was during this event that I first heard of the concept of lab meat as a strategy to curb methane– a potent greenhouse gas. This introduced me to the field of climate change and ignited my passion to find more sustainable ways to address the climate crisis while preserving the value of cows.
Because of my background in microbiology and molecular biology, the question then became how can we solve this at a molecular level? After reviewing the literature, I realized cows do not make methane, it’s the tiny little microorganisms called methanogens which are responsible for methane generation. With the help of genetic engineering tools like CRISPR technology I reasoned we could manipulate these organisms to stop producing methane and make other products that will enhance cows’ productivity. So, killing 2 birds with one stone. After three years of unsuccessful applications, I finally received a scholarship to pursue a PhD in a different area- maize fungus. One year into that project, my idea on mitigating cow methane emissions was recognized and funded by Rsif, and I could not think twice.
Q: How did your participation in COP28 impact you on both a personal and professional level? What significance did the recognition of your work hold for your ongoing efforts in climate change research?
A: Being recognized on a global stage like the COP28 in Dubai last year, confirmed that I am on the right path. Beyond the financial support, this recognition has expanded my network, provided access to world-class facilities, and connected me with leading experts in my field. I have had the opportunity to conduct research at prestigious methanogen facilities, such as the University of Connecticut (UConn), USA and Synthetic Biology Lab at Worcester Polytechnique Institute, USA. Additionally, I am now a member of Archaea Hour, a community that connects all archaea labs across America and Europe to facilitate the flow of knowledge, foster research collaborations and support outreach efforts. I’m also part of the American Institute of Chemical Engineers, where members contribute significantly to advancing engineering, science, and technology.

Q: How has receiving the Rsif scholarship influenced your academic and professional path in climate research? Are there any key opportunities or experiences facilitated by the program that have been particularly instrumental in advancing your work?
A: This project would not have materialized without financial support from Rsif. Having a great idea is one thing, but without funding, it remains just an idea. Rsif has profoundly impacted my life beyond just the academic and professional spheres. The program’s unique structure, which allowed me to study at an African institution (in Nigeria) before undertaking research placements globally (in the USA), has been truly transformative. This experience has profoundly reshaped my perspectives, challenging me to adopt a more balanced and inclusive view of the world.
I have come to understand that solving complex problems, such as climate change, requires diverse perspectives and expertise from various disciplines and backgrounds. Sustainable solutions are built through collaborative efforts that incorporate a wide range of viewpoints and experiences.
Q: In what ways has Rsif’s focus on empowering African scholars helped bring your work to global platforms like COP28? Can you provide examples of how this international exposure has shaped your research and collaborations?
A: For me Rsif set a competitive and inspirational grounds which motivated me to work even harder. When you are given the opportunity to hear the journey of those who have excelled in your research interests, you see possibilities. I am deeply grateful for the Rsif seminars, workshops and trainings where invited guests shared their stories. These experiences broadened my perspective and helped me to develop research ideas that meet global standards.
Q: What is your perspective on the importance of African-led climate research, especially regarding the protection of the ozone layer and other pressing environmental challenges? How does your research contribute to filling those gaps?
A: It is true that African data is missing from the global stage, and Rsif is working to change that by empowering Africans to conduct research within our own contexts. This not only helps fill the gaps in global knowledge but also allows us to make informed decisions on greenhouse gas mitigation strategies tailored to our region. One of my objectives has been to profile microorganisms that directly or indirectly contribute to methane emissions from cows in Tanzania. Due to the limited data from our region, identifying some of these organisms has been challenging, as existing databases are often dominated by information from outside Africa. My research aims to address these gaps. We are currently conducting a global analysis to compare and understand where we stand. Preliminary findings from this work have also provided a solid foundation for our genetic engineering work on methanogens.
Q: How do you see your work contributing to building Africa’s capacity for climate research, particularly in addressing environmental sustainability and the preservation of the ozone layer?
A: My research has generated new insights into the rumen microbiome, paving the way for novel interventions to reduce methane emissions from livestock. The detailed profiles of rumen microorganisms responsible for methane production developed in this study are valuable for microbial-based animal breeding strategies aimed at protecting the ozone layer—contributing to the idea of “green cows.” If the engineered strain we are developing proves successful, it has the potential to extend beyond Africa.
Q: Looking ahead, how do you envision Rsif and similar initiatives shaping the future of climate research in Africa? How has being part of this program empowered you as a young scholar in this space?
A: As an Rsif awardee, I envision Rsif and similar initiatives playing a transformative role in shaping the future of climate research in Africa by fostering a new generation of scientists who are equipped with the skills, resources, and networks needed to address our continent’s unique climate challenges. Rsif’s focus on advanced training, collaboration, and research within Africa, combined with international exposure, is creating a dynamic research environment that encourages innovative, locally relevant solutions. By supporting high-impact research in areas like climate change and environmental sustainability, Rsif is helping to build a solid foundation for evidence-based policy-making and sustainable development across Africa.
