NAIROBI, Kenya – Dust, construction noise, traffic congestion and potential damage to vegetation are among the environmental concerns facing the proposed Sh4.5 billion University of Nairobi Science and Engineering Complex, as the National Environment Management Authority (NEMA) invites Kenyans to scrutinise the project before making its decision.
In a notice dated October 27, 2026, the environmental regulator invited members of the public to submit comments on the proposed development at the university’s Chiromo Campus, placing environmental protection and compliance with planning requirements at the centre of the project’s approval process.
The public has 30 days from publication of the notice to submit oral or written representations to NEMA, giving residents, environmental stakeholders and other interested parties an opportunity to raise concerns before the authority determines the project’s environmental and social impact assessment.
The review comes as the Kenya-France-backed development advances through its preparatory stages, with the university having previously indicated that construction could begin in 2027, subject to the completion of key milestones.
Dust, noise and water pollution among concerns
NEMA has identified several potential environmental risks associated with construction, including dust emissions, noise pollution, soil erosion, water contamination, traffic disruption and interference with existing vegetation and biodiversity.
To limit damage to the surrounding environment, the authority has recommended phased land clearance, replanting trees—particularly indigenous species—and protecting vegetation in environmentally sensitive areas.
Construction teams are also expected to adopt measures to control dust, including installing dust screens and regularly spraying water on exposed surfaces and work areas.
Noise-generating activities should mainly be undertaken during daytime hours, while workers should be provided with appropriate protective equipment.
The recommendations are intended to reduce the effects of construction on the surrounding community while ensuring that work proceeds in accordance with applicable environmental requirements.
NEMA flags riparian reserve and planning approvals
Beyond construction-related pollution, the authority has emphasised the need for the university to secure the necessary approvals from relevant government agencies and comply with applicable planning requirements.
The notice also highlights the 30-metre riparian reserve requirement for waterways that could be affected by the proposed development.
Riparian reserves help protect watercourses and surrounding ecosystems from encroachment, erosion and pollution. The applicable boundary and restrictions must be established in accordance with the relevant legal and regulatory requirements for the site.
To prevent water contamination, NEMA has proposed controlled fuel storage, procedures for responding to spills and proper disposal of concrete wash water and laboratory effluent.
The last measure is particularly relevant to a complex intended to support science and engineering training, where laboratory operations will require appropriate systems for managing wastewater and other potentially hazardous materials.
Traffic management is another issue under review. Proposed safeguards include designated delivery routes, construction traffic plans, safety signage and measures to protect pedestrians while limiting congestion around the campus.
What the France-backed project will deliver
The Science and Engineering Complex was announced by President William Ruto during the Africa Forward Summit on May 11, 2026, attended by French President Emmanuel Macron.
The project is valued at approximately Sh4.5 billion, equivalent to €35 million, and is funded by the French Development Agency (AFD), with support from the Kenyan and French governments.
Planned for the university’s Chiromo Campus, the facility is intended to strengthen Kenya’s capacity for science and engineering education, research and innovation.
The complex is expected to support interdisciplinary research and training in areas including artificial intelligence and data, green energy, sustainable chemistry, agriculture and food, health, advanced manufacturing and urban development.
The university’s procurement documents describe a multipurpose academic hub with a maximum of five storeys and an approximate gross built-up area of 28,302 square metres.
The development is also intended to expand training capacity and strengthen collaboration between researchers, students and industry, positioning the institution to contribute to technological innovation and skills development.
Public has 30 days to raise objections or concerns
NEMA’s invitation gives members of the public an opportunity to submit views that may inform its assessment of the project.
The authority says submissions should be addressed to its Director-General and should quote the relevant project reference number.
Comments may be emailed to info@nema.go.ke. The notice gives the reference as NEMA/ENVIS/SR/00661, although another reference, NEMA/ESIA/SR/9066, also appears in the supplied material and should be confirmed against the original notice before submission.
The public consultation is a key step in assessing whether the proposed development has adequately addressed its potential environmental and social effects and identified appropriate mitigation measures.
The university has previously said the project is progressing through technical and implementation preparations, with groundbreaking expected in March 2027 if the required milestones are met.
NEMA’s review will therefore help determine the environmental safeguards required as the university and its French partners work towards delivering one of the institution’s major planned science and engineering facilities.
