Turning satellite data into solutions for farmers, cities and mines

When Samuel Ishimwe talks about satellites, he is quick to move the conversation away from space. Instead, he talks about maize fields in Nyagatare, droughts that can be detected before crops begin to wither, and landslides that could be predicted before they claim lives. For Ishimwe, who recently completed a master’s degree in Space Technology Applications at Beihang University in Hangzhou, China, the true value of space technology lies not in orbit but in the everyday challenges it can help address on the ground.

One project focused on crop monitoring in Nyagatare District, where satellite imagery and artificial intelligence were used to identify crops such as maize and beans and monitor their performance over time. “The purpose of these analyses is to support decision-makers such as the Ministry of Agriculture and institutions like Rwanda Agriculture and Animal Resources Development Board (RAB),” Ishimwe said. “Satellite data can help identify drought because the images use different spectral bands that reveal changes in vegetation before they become visible to the naked eye.” The team also used AI-powered platforms that allow users to monitor farmland remotely. “Instead of manually analysing satellite images, users can ask questions through an AI chatbot and receive dashboards, charts and graphs showing the condition of specific farms,” he said.

He believes the technology has practical applications that extend beyond research. “In a country like Rwanda, which has many hills, it is difficult to collect data everywhere on the ground,” he said. “High-resolution satellite imagery makes it easier to monitor farms and other areas that are not easily accessible.” The technology can also support urban planning, infrastructure development, disaster management and environmental protection. Historical satellite data can help identify areas vulnerable to floods and landslides, while frequent imagery can reveal unauthorised construction and other changes on the landscape. Ishimwe says one of the biggest lessons he gained from his experience is that countries do not necessarily need to own satellites to benefit from space technology.

What matters, he argues, is having skilled people who can transform that data into useful information. “Once we build enough expertise, we will be able to process our own data and generate information that helps institutions and policymakers make better decisions,” he said. His classmate, Eric Ibyishaka, shares the same vision. After studying Electronics and Telecommunication Engineering at the University of Rwanda and later pursuing a master’s degree in Electrical and Computer Engineering at Carnegie Mellon University Africa, Ibyishaka specialised in remote sensing and Geographic Information Systems before joining the same master’s programme in China. One challenge stood out during his studies. “I kept reading reports of people dying in illegal mining sites,” he said. Those reports inspired his research on using satellite imagery to detect newly established open-pit mines, giving authorities an opportunity to identify illegal or unsafe mining operations earlier. “The technology can help the government know where new mines have appeared and determine whether they are operating legally,” Ibyishaka said. “It can also reduce deaths caused by unsafe mining.” During their internship, the two engineers also worked on tea suitability analysis, examining how climate change could gradually push tea cultivation towards higher elevations as temperatures rise and rainfall patterns change. Ibyishaka said one of the most remarkable innovations he encountered was seeing satellites process data while still in space.

Their experience comes as Rwanda continues to invest in developing capacity in the space sector. Through partnerships with universities and international institutions, the Rwanda Space Agency has supported Rwandan students to pursue advanced studies in space-related fields while working to establish a space engineering programme at the University of Rwanda to train future specialists. Despite the progress, the sector still faces shortages of expertise in specialised fields such as artificial intelligence, satellite engineering and space regulation.
