Gabions and Reno Mattresses halt erosion at Ikot Anwatim gullies, Calabar

anwatim

The project is part of the Nigeria Erosion and Watershed Management Project (NEWMAP)

The NEWMAP program intervened to stop erosion of the Ikot Anwatim gullies. Our Reno Mattresses and geotextiles were installed to address erosion and gabion check-dams were constructed at intervals to reduce peak velocity flow.

Ikot Anwatim is a community in Calabar, Cross River State. Due to poor environmental management and uncontrolled land clearing, the area was suffering from landslides and increased storm water run-off, which accelerated the erosion of the gullies spreading through the area.

The Ikot Anwatim area is intersected by a complex gully with five tributaries which cuts across settlements and farmland including the major communities of the Calabar municipality such as Ikot Ansa, Ekorinim, Esuk Utan, Ikot Akpanam and Kasuk. The gully also gradually extends towards the Murtala Mohammed highway, a major road in Calabar.

The Nigeria Erosion and Watershed Management Program (NEWMAP) was created by The Federal Ministry of Environment and The World Bank and its partner agencies to address the challenges of gully erosion, land degradation and environmental insecurity. It has appraised the situation of Ikot Anwatim with the help of the local consultant Rabiona Engineering.

The consultant, Rabiona Engineering suggested the use of our gabions to construct a series of check-dams at intervals and at the foot of the steep slopes to reduce the peak velocity flow. Our Reno Mattresses and geotextiles were also installed to stop further erosion of the slopes.

This solution has proved to be effective as vegetation is gradually re-established and gully erosion has been stopped.
