Erosion, Flood and Coastal Zone Management
The problems of soil erosion (both coastal and inland) and flood are the most devastating land degradation processes in all parts of the country. Erosion has adversely affected social and economic growth of many local communities in Nigeria. This menace poses serious socio-economic problems ranging from rural/urban migration and displacement of populations because of declining agricultural productivity, to loss of beaches and tourism potentials as well as to private properties.
Soil Erosion (Sheet, Rill and Gulley) is affecting the whole country and is certainly the worst from of land degradation facing us. It is estimated that there are over 2000 active gulley Erosion sites across the country with 505 of them being located in south Eastern part of the country especially in Abia and Anamabra States.
Also in a recent stakeholders meeting organized by the Ministry about 137 very active sites that need over N38 billon for immediate remediation have been identified all over the country.
Soil Erosion Achievements
In this sector, various Erosion sites have been identified, studied, designed control measures put in place based on the following integrated approach.
- Funding of control works of identified Gully Erosion sites
- Project formulation and implementation
- Education and Awareness Campaign
- Community participatory on preventive measures.
Presently the ministry is undertaking various Erosion Projects in Adamawa, Bauchi, Anambra, Imo, Jigawa, Ogun and Kwara States.
Floods of unprecedented magnitude have taken place in all the States of the Federation of recent. This huge increase in frequency arises from both natural and man made causes. For each of these floods, billions of Naira damages to infrastructure are recorded and subsequently such amounts are needed for rehabilitation.
Flood Control Achievements
In order to manage flood, the Ministry has therefore adopted the following strategies for flood management.
- Regulation on the use of flood plains
- Flood plain Management through good practices that will reduce flood run-offs
- Flood plain mapping/flood risk study
- Engineering design/solutions
- Introduction of water harvesting and management through impoundment of excess water by small scale dams and other storage structures. Various flood control projects are being executed in Lagos, Kwara, Adamawa, Benue and Jigawa States.
Coastal Erosion, the whole of the coastline of the country spanning a length of 850km is being eroded progressively with the Bar beach problem in Lagos being the most prominent.
Coastal Erosion Achievements
The Ministry through the years has been undertaking projects along the coastline to control coastal erosion especially along the Lagos Shoreline with the Bar Beach Project as being the most prominent.
The Ministry has shifted its emphasis from the remedial measures (Bar Beach) to a permanent one based on a well articulated method of planning, investigation, design of a sustainable and lasting solution, construction, monitoring and maintenance. This involves the participation by other stakeholders through public/private partnership arrangement. The ministry is presently undertaking projects in coastal protection in Lagos States.
Strategies for Addressing Erosion & Flood
In order to arrest or at least ameliorate the escalating problems, the Ministry has undertaken the following strategies:
- Monitoring, assessment, mapping, inventorization and generation of baseline environment data for the prevention, mitigation and control of hydro- meteorological related disasters in Nigeria
- Land reclamation
- Development of Soil Conservation policy and master plan towards efficient land use practices in Nigeria
- Processing and management of satellite data for management of hydro-metrological related disasters in Nigeria-flood, erosion, water harvest & Coastal Erosion
- Monitoring the impact of global change and associated impacts on flood, inland and coastal Erosion
- Inter-basin water transfer from regions of surpluses to region of deficits for water harvesting for flesh flood prevention
- Formulation of resettlement strategies, emergency preparedness plans, and sociological aspects of coping with flood in affected areas in the country in cooperation with other related agencies
- Development and operation of flood, early warning systems
- Studies and designs for control of Soil Erosion, Flood Coastal Zones Management water harvesting and management
- Public enlightenment on prevention, mitigation and control of Flood Erosion and Coastal Zone Degradation
- Operation and Maintenance of installed physical structures for control of flood and erosion, to ensure optimum efficiency and achievement of designed life spans of such structures
- Protection and management of coastal shoreline against coastal erosion and coastal degradation
- Establishing linkages with agencies with similar mandates
