I am once again eager to engage critical stakeholders in discussing the crucial issue of good governance in Edo State, especially concerning the pressing problem of flooding and erosion. The recent incident involving Governor Godwin Obaseki getting stuck in floodwaters at RCC area on Sapele Road, Benin City, serves as a powerful motivator for our conversation.
As an environmentalist well-versed in flooding and erosion, particularly in Edo State, I was not surprised by the occurrence. Edo State is blessed with abundant natural resources, but it faces significant environmental and ecological challenges, including waste management, pollution, sanitation, forest depletion, flooding, and soil erosion. These natural hazards not only disrupt the lives of residents but also cause significant damage to infrastructure and the environment.
According to the Edo State Strategic Health Development Plan (2010-2015), flooding and erosion are ranked as the first and second most pressing environmental problems in the state.
In the face of the pressing challenges of flooding and erosion in Edo State, it is imperative for us to set aside political bickering and unite behind a common purpose. Instead of being divided, we must collaborate and focus our efforts on devising holistic strategies and implementing effective measures to combat these environmental issues and safeguard the well-being of our communities.
To effectively address the erosion and flooding issues in the State, substantial resources are required. One of the key initiatives already in place is the NEWMAP (Nigeria Erosion and Watershed Management Project) intervention, which was established in 2012. However, to ensure the successful implementation of these control measures, it is crucial to involve and engage local communities at all stages of the NEWMAP intervention programmes.
The officials responsible for environmental management within the State must have a comprehensive understanding of the processes involved in gully evolution. Factors such as soil bulk density, soil texture, compressional strength, and moisture content play critical roles in the development of erosion. Therefore, civil engineering solutions like constructing retaining walls, erosion brakes, side drains, channels, and backfilling should be complemented with biological measures, such as planting trees and crops to stabilize the soil.
Collaboration among various agencies is essential to effectively combat the erosion and flooding challenges. The Department of Erosion, Flood Control, and Coastal Zone Management, the Federal Ministry of Environment, Nigeria Hydrological Services Agency (NIHSA), Federal Ministry of Water Resources, Nigeria Erosion and Watershed Management Project (NEWMAP), River Basin Development Authorities (RBDAs), and the State Ministry of Environment should work together and continuously monitor the effectiveness of control measures implemented in the area.

Addressing the socio-economic challenges resulting from gully erosion disasters is crucial. By providing alternative livelihood opportunities and support to communities affected by erosion, the undue pressure on the soil in these areas can be reduced. Additionally, relevant environmental laws and policies should be reviewed and adapted to suit the current and anticipated soil erosion problems.
Mechanical control measures, such as culverts, drainages, and speed breakers, should be implemented with a thorough understanding of hydraulic actions. Establishing Erosion Monitoring Posts (EMPs) in the three geopolitical zones of Edo State will enhance the capacity for monitoring soil resources and enable early responses to gully erosion issues.
The active involvement of local communities in the implementation of control measures will significantly enhance their effectiveness. Policymakers must collaborate with experts in environmental management to tackle the gully erosion problems in the area, recognizing that soil is a non-renewable resource that needs to be conserved for future generations.
The State government must immediately promote public awareness campaigns about the causes and consequences of flooding and erosion. Educate residents about sustainable land-use practices, waste disposal, and the importance of protecting natural resources. Empower communities to take an active role in preserving their environment. Develop and implement early warning systems for floods and erosion. This includes installing rain gauges, water level sensors, and weather monitoring stations to provide timely alerts to communities at risk. Effective early warning systems can save lives and reduce property damage. Invest in climate-resilient infrastructure to withstand extreme weather events. Roads, bridges, and buildings should be designed with flood and erosion risk in mind, using appropriate engineering techniques and materials. Encourage sustainable urban planning practices that prioritize green spaces, permeable surfaces, and natural drainage systems. Implementing green roofs and rain gardens can reduce surface runoff and mitigate the impact of floods. Enhance the capacity of relevant agencies and departments responsible for flood and erosion management. Training and resources should be provided to improve their ability to respond effectively to environmental challenges. Conduct research and collect data on flood and erosion patterns in Edo State.
This information will help in developing accurate flood maps, identifying vulnerable areas, and formulating evidence-based policies. Evaluate existing land use policies and regulations to ensure they align with sustainable environmental practices. Stricter enforcement of these policies will prevent indiscriminate land use that exacerbates flooding and erosion.
In conclusion, addressing the challenges of flooding and erosion in Edo State requires a multi-faceted and collaborative approach involving various stakeholders, including government agencies, local communities, environmental experts, and policymakers. By implementing these measures and incorporating environmental considerations into governance, Edo State can become a model of good governance and sustainable development in Nigeria.
By prioritizing these issues of good governance, environmental management, and disaster mitigation, we can work towards a more sustainable and resilient future for Edo State and its communities. Let us take this opportunity to drive positive change and protect our natural heritage for the benefit of all.
