Abstract

The right to adequate housing is one of the key sustainable development goals of the United Nations, and a fundamental human right. Community-based adaptation is also a central theme in building resilience to flooding. The Niger Delta Region of Nigeria is the 9th largest wetland in the world, through which the River Niger discharges into the Atlantic Ocean. As such, the geotechnical and hydrological characteristics of most parts of the Niger Delta area dictate the necessity for effective practical measures to satisfy the engineering demands of the highly compressible silty clay soils for housing construction in coastal communities. Field work data gathered from local builders in Bonny Island reveal the implied technicalities of managing and coping with terrain related factors, which translate into additional cost for projects in riverine areas, and whose prohibitive cost has been termed ‘unfeasible’. Considering the numerous cases of building failure and collapse in the Niger Delta region, it is thus worrisome that private speculative developers may resort to taking shortcuts, which may undermine the safety of building inhabitants. Due to the scarcity of suitable lands, the recognition that coastal communities in the Niger Delta can only cope with issues of flooding by devoting funds to adequate structural adaptation mechanisms in buildings has thus become pivotal. Against the backdrop of the astronomical cost of housing in the Niger Delta, this study analyses the geo-environmental factors contributing to the high cost of construction, as a basis of creating heightened awareness of the need to institute relevant policy driven technical checks and capital incentives to small scale developers, who provide the bulk of housing in coastal communities.
