A review of Sebeya Catchment restoration, highlighting lateral dykes, erosion control, and sustainable water engineering in Rwanda.                                 The Sebeya Catchment is one of Rwanda’s most environmentally sensitive and highly monitored river basins due to its long-standing vulnerability to flooding and severe soil erosion. Located within the Congo Basin and covering an estimated area of over 363 km² , the catchment spans 21 sectors across Rubavu, Rutsiro, Ngororero, and Nyabihu districts . Its steep mountainous terrain combined with high annual rainfall creates ideal conditions for accelerated runoff, sediment transport, and destructive floods. Over the past decades, Sebeya has experienced multiple flood-related disasters that caused loss of life, destruction of property, and environmental degradation. These recurring events positioned the catchment as a national priority for research, ...

Rwanda has undergone a remarkable engineering transformation over the last three decades, shifting from a period of severe environmental strain and post-conflict rehabilitation to a modern era defined by hydro-engineering , environmental restoration , and ambitious national infrastructure.  This article analyses Rwanda’s engineering progress from 1994 to 2025 , spotlighting the mega-projects that have shaped national development across energy access, water security , climate resilience , and economic growth. This article intends to review the evolution of Rwanda’s engineering landscape, the rise of high-value mega-projects, and the measurable outcomes across key sectors. With large-scale investments and increasingly sophisticated engineering capacity, Rwanda is now entering its strongest phase of infrastructure delivery. Inline references are included for contextual grounding, and the discussion highlights how engineering excellence is central to Rwanda’s sustainable development tr...

  Kigali is investing millions to restore five wetlands. Learn how engineering is tackling runoff, climate resilience, and boosting eco-tourism. Kigali is reshaping its future with one of the most ambitious environmental projects in the region. The city is rehabilitating five wetlands covering a total of 491 hectares. These wetlands include Gikondo , Rwampara, Rugenge-Rwintare, Kibumba and Nyabugogo . Their restoration is designed to improve flood control , protect biodiversity, and create new opportunities for citizens. The project also builds on Rwanda’s commitment to climate resilience and sustainable urban development. The total investment is estimated at 82 million US dollars, which is about 108 billion Rwandan francs . Funding comes from both government resources and development partners. Already, about 30 million US dollars, or 40 billion francs, has been invested in the first phase of conservation works and infrastructure. The project is currently at 67.3 percent comple...
