ln a naturally vegetated area, the force of rain drops is dampened and its flow velocity slowed down tom aid percolation into the soil resulting in minimal run-off. With rapid urban development and adoption of wrong construction practices, natural vegetation has given way to non-permeable surfaces like roof tops, road surface and other surface treatments, causing significant increase in surface run-off.
Household and Community Rainwater Harvesting reduces the amount of surface run-off and velocity of flow, thereby removing the scouring power of the rainwater that causes erosion in our towns and communities. The practice involves collection of rainwater from roofs and storing them in specially designed tanks for domestic, agricultural, recreational and other applications.
ln each of the affected gully areas, a mapping of the various threats identified by the communities as their main worries as well as the vehicles for them to upgrade themselves was carried out. The Project engaged the service of non-governmental organizations who are more in tune with the aspirations of communities to guide them how to take advantage of the opportunity that NEWMAP has provided for training, capacity building and provision of seed money that will help kick-start investments in the trades they have chosen so as to improve their livelihood and welfare.
This is done in such a way that the activities chosen are site-specific and to an extent community-specific to address the peculiar nature of the problems that these communities encounter. Community members are formed into Community Interest Groups and they engage in their choice livelihood activities that include; iron bending, snail rearing, tailoring, poultry, welding, waste management, etc. These are activities that are directly tied to helping stabilize the civil works that have been done.
is supporting the State Government with a study to mitigate the perennial flooding in the Onitsha metropolis & its immediate environs. Known as the Onitsha Urban Stormwater Management Masterplan, the project which is under NEWMAP component ZB, involves understanding the flood and drainage discharge patterns with intent on developing a lasting solution for Onitsha and its environs. This is made possible through the State Government‘s partnership with the Special Climate Change Fund (SCCF) under the Nigeria Erosion and Watershed Management Project (NEWMAP).
