Mak Student’s Push-Pull App to Help Farmers Control Maize & Sorghum Pests
Published
4 years agoon

By Jane Anyango
Makerere University student Paul Mugisha in collaboration with a team of scientists from the International Centre of Insect Physiology and Ecology (ICIPE), Keele University and Leeds University has developed a mobile app to help maize and sorghum farmers to control pests without using pesticides.
Paul Mugisha is undertaking a Master of Science in Plant breeding and Seed systems at Makerere University’s Department of Agricultural Production, School of Agricultural Sciences under the College of Agricultural and Environmental Sciences (CAES). Mugisha is also the Chief Executive Officer (CEO) Agape Innovations Ltd.
The purpose of this app is to enable a farmer to do push-pull on his garden without interacting with an extension agent but purely using his mobile phone which does not only solve the problem of scarcity of extension workers, but also, prevents the spread of COVID-19.
The new app code-named, “the Push-Pull App”, was launched and made available for use on Google play store on 9th August, 2021 by an international team of scientists to support farmers across Africa to use innovative, environmentally-friendly techniques for evading crop pests.
In a press release issued during the launch, scientists noted that African smallholder farmers face major challenges from insect pests such as fall armyworm, and weeds such as striga that can destroy their crops. Fall armyworm is a serious threat to food security and livelihoods and already affects at least 400,000 hectares, causing crop losses worth an estimated $3 billion a year.
In the release, the “Push-Pull technology” was described as a novel method of crop management and a solution which can massively reduce farmers’ losses from pests and increase their harvest sizes, whilst avoiding the need to use harmful and expensive chemical pesticides.
The media release in part states that the “Push-Pull technology” is a scientific method of planting crops like maize and sorghum, alongside particular species of forage grasses and legumes that repel pests and supress weeds.
“It was developed by scientists at ICIPE in Kenya and partners and is designed to protect the plants against devastating pests like the fall armyworm and the striga weed, with the companion plants also improving soil fertility. But a major challenge is how to communicate advice and information about this to millions of smallholder farmers in sub-Saharan Africa, to get as many of them using the technique as possible.

To help address this challenge, a new mobile phone app has been launched by Agape Innovations Ltd, in collaboration a team of scientists from the University of Leeds, University of Keele and ICIPE.
The app is part of a larger project called, “Scaling up Bio control Innovations in Africa”, funded by the Global Challenges Research Fund, which seeks to understand how biocontrol methods have been used across Africa and to encourage their uptake”, part of the media release states.
The Principal Investigator (PI) Dr Steve Sait, from the University of Leeds’ School of Biology, said the Push-Pull method of pest control is decades old and is used successfully by thousands of smallholder farmers across Africa.
“We hope that this collaboration, and this new app, can help us extend knowledge of this technique to potentially millions of other farmers who could be benefitting from it. Compared to chemical pesticides, Push-Pull costs less money to the farmer, results in less damage to their crops, and it avoids harming other insect species that play valuable roles in the ecosystem.”
The PI said, research by the scientists behind the Push-Pull technique, including Keele’s Professor Toby Bruce, has proven that odours released by the companion plants can effectively repel fall armyworm and protect crops against the pest.
Early adopter farmers according to the scientists have had great success with this technique, reporting five times less fall armyworm damage and a doubling or even tripling of crop yield, showing the huge potential this has for farmers and crop-producing smallholders.In addition he said, It also reduces the environmental impact of farming by protecting against pests without using pesticides, as well as improving soil quality without inorganic fertilisers.
Dr. Steve Sait explained that the Push-Pull App has been developed by Agape innovations and is available on Android phones, designed to work on the basic smartphones that are being increasingly used by smallholder farmers in Africa.
The App he adds, gives farmers information they need to get started with Push-Pull farming, and is not only free but 100% available offline, meaning a lack of internet connection in rural regions will not affect its function.
“The ultimate goal is to provide a resource for farmers that is informed by science, protects their crops and improves their harvest, which they can access any time of day from anywhere in the world”.
Professor Toby Bruce from Keele University’s School of Life Sciences said the team was excited to see if this App can serve as a vehicle for taking practical information to the farmer.
“It is designed to share key details about how to get started with Push-Pull. We hope this will increase the number of farmers taking up this innovative approach that provides real benefits by improving crop protection and food security.”Prof. Toby Bruce said.
Makerere University student- the App designer Mr.Paul Mugisha, who is also CEO of Agape Innovations Ltd underscored the significance of ICT in addressing farmers’ challenges in critical challenging times involving natural calamities.
“With the world going digital and uncertainties like Covid-19 amplifying the challenges of physical interactions, ICT is so vital in today and tomorrow’s agriculture. At Agape, we built the Push-Pull app as a global tool to equip a farmer with all that is needed for a successful push-pull garden.
Embedded with audio, visual and graphical expressions we are certain that the Push-Pull app will be relevant to maize and sorghum farmers worldwide for both today and tomorrow in controlling FAW, Striga and Maize stalk borer”, Mr. Mugisha explained.
Mugisha said, in this Push and Pull technology, maize is intercropped with legumes, and forage grasses are planted around this intercrop as a border around the garden. The legume intercrop produces chemicals that repels the pests from the garden (push) while the forage grass in the boundary produces chemicals that attracting insect pests (pull). In addition, the chemicals released by the intercrop roots also cause abortive germination of the parasitic striga weed, providing effective control of this stubborn weed. The legume also fixes nitrogen into the soil thus boosting soil productivity..
More about the PUSH-PULL App

What is Push-Pull App?
PUSH-PULL app is a mobile application that serves as a guide to a farmer whose interest is to control pests in maize and sorghum (like fall army worm and maize stem borer) without using chemicals and also improve the soil conditions without using artificial fertilizers.
The PUSH-PULL app acts as an extension agent on a farmer’s mobile phone providing information about a farming method called push-pull that was developed by scientists at ICIPE, a method that uses natural means for pest control and soil improvement.
What problem is PUSH-PULL app trying to solve?
With PUSH-PULL app, a farmer can access information at anytime of the day be at 6 am on a Sunday morning or at Thursday mid-night, something that is not possible with an extension agent. With this app, a farmer can access information anywhere, whether in his car, in his garden or on his way to the shop. Information is conveniently available for the farmer. With this app, farmers all over the world can access the information on their phones. Whether in Cambodia, Ecuador or in Burkina faso, push-pull information is available

Mak Hosts TORCH Project Training Workshop on Clean Energy & Green Growth
Published
1 week agoon
October 2, 2025
Written by Matila Tom Micah
Makerere University on 1st September 2025 held a training and retooling workshop for stakeholders under the TORCH Project. TORCH is a collaborative initiative between Makerere University, the University of Natural Resources and Life Sciences-BOKU, Kyambogo University, Kabale University, University of Juba, and Busitema University. Funded by the OeAD-GmbH under the Austrian Partnership Programme in Higher Education Research for Development (APPEAR), the project seeks to strengthen cooperation between academia and local communities to promote green growth and environmental sustainability. The project aims to promote academic-community partnerships through living labs, training, research, and outreach.
The workshop, held under the theme “Towards a Clean Energy and Zero-Emission Society in East Africa: Strengthening Academic and Community Collaborations in Outreach, Training, and Research in Green Growth and a Healthy Environment”, brought together academics, students, policymakers, and community leaders. Together, they explored strategies for green growth, climate resilience, and sustainable development.
Dr. Patrick Musinguzi, TORCH’s Principal Investigator, opened the event with an overview of the project, explaining key concepts such as green growth and the innovative Living Labs approach. He underscored the urgent need for African universities to lead the charge in green growth, a development model balancing economic progress with natural resource conservation and reduced greenhouse gas emissions.
While the country has adopted the Uganda Green Growth Development Strategy, Dr. Musinguzi pointed out that universities have yet to fully integrate green growth principles into curricula, research, and community engagement. TORCH aims to bridge this gap by establishing three Living Labs in the Central, South-western, and Eastern regions of Uganda, focusing on enhancing teaching, community-driven research, and policy development.
Green Growth
In his presentation, Dr. Musinguzi emphasized the importance of adopting green growth as Uganda’s path to development. He described green growth as “environmentally sustainable economic progress that encourages low-carbon, socially inclusive development.” “Green growth is not merely about environmental protection – it is about creating a future where economic prosperity, social equity, and environmental sustainability coexist,” he explained.

Why Green Growth matters for Uganda
With Uganda’s rapidly growing population placing immense pressure on land, food, and energy resources, Dr. Musinguzi pointed out that per capita land ownership had significantly decreased, while climate change impacts such as floods, prolonged droughts, and erratic rainfall continue to threaten food security.
He stressed that pursuing green growth offers Uganda multiple benefits:
- For farmers, it ensures resilience to climate shocks, better yields, and access to innovations like solar irrigation and biogas.
- For the youth, it opens up new job opportunities in renewable energy, waste management, and eco-friendly enterprises.
- For policymakers, it aligns development plans with environmental sustainability while attracting green investments.
- For households, it reduces energy costs, improves health, and enhances overall well-being.
Uganda’s policy commitments
The workshop highlighted national frameworks already in place to support green growth, including the National Environment Act (2019), the Climate Change Act (2021), and the Uganda Green Growth Development Strategy (2017–2030). These policies, coupled with Uganda’s Vision 2040, set a clear direction for a low-carbon and climate-resilient economy.
Green technologies being piloted under the TORCH Project
During the workshop, Dr. Musinguzi showcased several practical innovations being piloted under the TORCH Project. These include:
- Solar home systems that cut fuel demand by up to 25%.
- Rainwater harvesting tanks that save 20,000–50,000 litres of water per household annually.
- Improved cook-stoves that reduce indoor air pollution and fuel consumption.
- Drip irrigation systems that minimize water loss by up to 60%.
- Biogas systems that convert organic waste into clean energy for households.
Despite these advances, uptake remains low. A 2024 UBOS report revealed that only 3% of Ugandan households currently use clean cooking fuels and technologies, way below international clean energy adoption targets.
The importance of Academia-community engagement in promoting green growth
The training emphasized the need for universities to serve as “living laboratories” for green innovations. Makerere University, through the TORCH Project, is integrating green growth concepts into its curricula, running pilot projects in communities, and training the next generation of sustainability leaders. “We are committed to bridging the gap between academic research and community transformation,” Dr. Musinguzi said. “Green growth must not remain in lecture halls, it has to be felt in farms, households, and cities across Uganda.”
Participants agreed that scaling up green growth is not just a policy ambition, but a national necessity. “With the right investments, awareness, and community involvement, Uganda can transition towards a zero-emission, climate-smart, and inclusive economy by 2040.”

Insights from Participants
- Dr James Wasike Mangeni from the Department of Sociology and Anthropology at Makerere University highlighted the need to rebuild social structures and foster responsible use of resources within the university, calling on leadership to reinforce environmental management and nurture respectful behaviours among students.
- Dr. Isaac Newton Alou from the Department of Soil Science and Land Use Management at Makerere University praised the green growth and Living Labs concepts, urging incorporation of sustainability into infrastructure projects like green and solar rooftops, and enhancing student-led data collection for impact assessment.
- Dr. Anthony Mwije from the Department of Crop Science and Horticulture, Makerere University stressed that green growth starts with personal discipline and should be embedded in university operations, including procurement and transport. He advocated for infrastructure supporting sustainable lifestyles, such as bicycle-friendly roads and reliable public transit.
- Dr. Olupot Giregon, Head, Department of Soil Science and Land Use Management at Makerere University raised concerns about the equitable distribution of green growth costs, especially for smallholder farmers, emphasizing stewardship and the importance of making green growth meaningful from curricula to end-users.

Living Labs: Innovation at community level
In rural Uganda, smoky cooking fires pose serious health risks for many families. The TORCH Project is tackling this issue by transforming households from passive energy users into active innovators, building a cleaner, healthier future.
At the heart of this initiative are Living Labs – community hubs where academia, industry, policymakers, and local residents collaborate to develop and test practical green technologies. These include biogas digesters that turn animal waste into clean fuel, solar power systems replacing hazardous kerosene lamps, energy-efficient stoves, and rainwater harvesting solutions.

“Living Labs empower communities, especially women, who face the greatest energy challenges, to lead sustainable transitions,” said Dr. Musinguzi. “Students also work directly with villages, gaining hands-on experience in addressing Africa’s energy needs. A significant advantage is linking these efforts to carbon credits, enabling families to generate income by reducing emissions and turning climate action into economic opportunity.”
The TORCH Project plans to expand Living Labs throughout East Africa, supported by digital tools to accelerate clean energy adoption, climate action, and poverty alleviation. More than just projects, these Labs foster community pride and position local residents as innovators in the fight against climate change.

Uganda Urged to Strengthen Extension Services to Realize Climate Smart Agriculture Goals

Fort Portal, Uganda
Uganda’s progress toward Climate Smart Agriculture (CSA) will remain limited unless deliberate efforts are made to strengthen agricultural extension services and turn policy intentions into real impact for farmers.
This was the key message delivered at a high-level policy dialogue held in Fort Portal, which brought together over 30 district officials, researchers, and policymakers from 11 districts across the Bunyoro and Rwenzori sub-regions.
The dialogue, held at Night Rose Hotel, was organized by the Environment for Development (EfD)–Mak Centre, under Makerere University, coordinated by the EfD Global Hub at the University of Gothenburg Sweden, funded by the Swedish International Development Cooperation Agency (Sida). The event aimed to deepen local understanding of CSA and strengthen connections between policy frameworks and implementation at the grassroots.
In his welcome remarks, Baguma Brian James, Senior Fisheries Officer for Kabarole District, thanked the EfD team for bringing such a relevant discussion to the region. He described the event as a moment of professional and academic reflection, noting that many participants had been reawakened to concepts they once encountered in school.
“I’d like to thank you all for being part of these valuable engagements,” Baguma said. “As Kabarole District, we are actively participating in this project. Our farmers are progressing toward co-funding stages for input support.” He expressed hope that the dialogue would not only offer technical knowledge but also actionable strategies participants could take home and apply.

Representing the Director of EfD-Mak Centre, Dr. Nicholas Kilimani underscored the importance of science in guiding agricultural decisions. He reminded participants that the EfD Centre’s functions include research, outreach, and policy engagement – all of which converge in dialogues like this one.
“The theme of this dialogue Smart Agriculture resonates with Uganda’s urgent need to sustain its agricultural backbone amid mounting pressures from climate change and human activity,” Dr. Kilimani said. He emphasized that decision-making must be grounded in scientific evidence rather than conjecture, pointing out that agriculture, while essential to Uganda’s economy, continues to suffer under environmental degradation, poor planning, and the effects of climate variability.
“We are no longer in an era of trial and error. Decision-making must come from science, not hearsay,” he added. Kilimani also highlighted the power of global collaboration, noting that the EfD network spans six continents, creating a powerful exchange of knowledge to support sustainability around the world. “We are using these global synergies to contribute to a sustainable planet—of which we only have one.”

Fort Portal Deputy Resident City Commissioner, Busingye Emmanuel, officially opened the dialogue and welcomed participants to the city. He applauded the event’s focus on climate-smart agriculture but lamented the widespread failure to enforce environmental laws and coordinate government action effectively.
“Uganda is not short of laws or institutions to protect the environment. The problem is either poor coordination or outright inaction,” Busingye said. He cited the continued degradation of wetlands in Fort Portal as a key example of where environmental protection efforts fall short. While several government agencies exist to enforce these policies, their actions are often fragmented or undermined by personal and political interests.
“If we did what we are supposed to do, we wouldn’t have this level of environmental destruction,” he added. Busingye further urged participants not to treat the event as a box-ticking exercise but as a launching point for real implementation on the ground. “Let’s not attend workshops and stop there. Let us act on the ground.”
Presenting an overview of CSA, Dr. Peter Babyenda revealed sobering statistics about land use and degradation. He noted that agriculture accounts for 72% of Uganda’s land use and that 41% of this land is already degraded. If the current trend continues, by 2040, nearly 90% of Uganda’s land could be under agricultural use, intensifying environmental stress.

“Our natural forest cover once fell to 9%, though efforts to promote CSA have raised it to around 30%,” Dr. Babyenda explained. He warned, however, that only 30% of farmers in Uganda are currently practicing climate-smart techniques — a dangerously low figure given the urgency of climate change.
“CSA offers a triple win increased productivity, improved resilience, and mitigation of greenhouse gas emissions,” he said. “But adoption remains low due to costs, lack of awareness, and poor access to technologies.” Dr. Babyenda also highlighted the European Union’s upcoming regulatory requirements on deforestation-free coffee exports, warning that Uganda could lose access to lucrative markets if it fails to embrace CSA practices. “Without climate-smart agriculture, our exports will suffer,” he stated.
Dr. Florence Lwiza Nsereko delivered an evidence-based presentation on CSA case studies and emphasized the critical role of extension services in scaling CSA. She reiterated that agriculture, deforestation, and other land-use forms like livestock production remain Uganda’s largest contributors to greenhouse gas emissions. Yet despite an abundance of policy documents, actual implementation remains weak.

“Climate Smart Agriculture integrates productivity, adaptation, and mitigation. But its adoption remains low because our extension services lack capacity,” Dr. Lwiza said. She pointed to key barriers in extension delivery, including lack of access to training, weak institutional support, and poor perceptions about CSA among field officers. Notably, she revealed that female extension workers often outperform their male counterparts in CSA delivery.
She further noted that Western Uganda is both highly vulnerable to climate shocks and densely populated, making it a prime candidate for CSA interventions. “Western Uganda is both a climate risk hotspot and an opportunity zone. Now is the time to act,” she concluded.
Adding another layer to the discussion, Dr. Aisha Nanyiti presented research on the role of renewable energy micro, small, and medium enterprises (MSMEs) in transforming agriculture across Sub-Saharan Africa and Southeast Asia. She argued that clean energy and climate-smart practices must be pursued together to achieve inclusive, low-carbon growth.

“Agricultural modernization and climate goals can go hand in hand — if we remove barriers to clean energy,” she said. She stressed the importance of financial access, supportive regulations, and targeted capacity building to ensure that MSMEs can support CSA.
Closing the dialogue, Deputy Speaker of Fort Portal City, Tusiime Florence, expressed gratitude to the organizers but raised concerns over the sustainability of such engagements. She urged EfD-Mak and its partners to avoid the common trend of one-off workshops that do not translate into long-term support for local governments.

“Workshops come and go, but no one returns to follow up with our communities,” she said. Tusiime called attention to the overwhelming workload and underfunding of agricultural extension officers, many of whom use their own money and have no transport to reach rural areas. “Our extension workers are overworked and underfunded. They have no motorcycles, no transport,” she said. “Yet they are expected to implement national climate and agricultural goals.”
She called for continued support and follow-through from Makerere University and the EfD-Mak Centre. “When farmers dry maize on bare soil, it’s not ignorance – it’s lack of training and support,” she noted. “If you come back and work with us, we will make CSA work.”
The Fort Portal dialogue highlighted the growing urgency to transition from policy declarations to farmer-level action, as climate shocks continue to impact agricultural livelihoods. While Uganda has made strides in crafting climate and agriculture policies — including Nationally Determined Contributions (NDCs) and CSA frameworks — weak operationalization, limited financing, and poor coordination remain major obstacles. Stakeholders agreed that building capacity, particularly among extension workers, remains the single most effective route to scaling climate-smart agriculture and delivering tangible impact where it matters most — at the farm.
