The Nigerian Institution of Environmental Engineers (NIEE) has warned that Nigeria is at a critical crossroads as cities and communities continue to face recurring flooding and climate-related disasters that demand science-driven, engineering-led solutions.

The NIEE, a division of the Nigerian Society of Engineers, expressed particular concern over recent coastal road flooding in Lagos, noting that failure to address the situation decisively could amount to an indictment of the engineering profession if professional solutions are not urgently applied.

Speaking at his inauguration as the 15th National Chairman of the institution in Abuja on Thursday, Caius Ikem Umekesiobi identified urban waste challenges, inadequate recycling systems, declining water quality and water scarcity, as well as air, water and land pollution, as major environmental flashpoints confronting Nigerian cities and communities.

He said these challenges have direct consequences for public health, ecosystem degradation and biodiversity loss.
The new chairman urged environmental engineers to embrace innovation and leadership in redefining Nigeria’s sustainability trajectory to achieve long-term, sustainable development.

Umekesiobi added that his administration would focus on strengthening institutional governance, expanding membership and chapter growth, enhancing professional development, boosting environmental monitoring and advocacy, and deepening collaboration and community engagement. He called on members to uphold togetherness and professionalism in pursuit of a sustainable environment.

Earlier, the outgoing National Chairman, Nursing Adegboyega Ogunyemi, said he was fulfilled by the progress recorded during his tenure, particularly in advancing national advocacy on pollution control, climate resilience, waste management and environmental governance.

He noted that the institution had built technical capacity among members and established strategic partnerships with government, academia and development institutions to promote innovation, sustainable practices and the revitalisation of student chapters.

Ogunyemi aligned with his successor’s views, stressing that waste-to-resource technologies, clean water and sanitation systems, renewable and low-carbon energy solutions, data-driven environmental monitoring and climate-smart infrastructure remain critical challenges that must be urgently addressed.

The inauguration ceremony also featured the conferment of fellowship on several engineers in recognition of their contributions to renewable energy systems, waste-to-wealth technologies, pollution control, climate mitigation and sustainable environmental policy.

Past national chairmen of the institution attended the event, which also witnessed the inauguration of members of the 2026 executive committee, with Yusuf Mojolagbe sworn in as National Secretary.
