Abstract: Flooding is a serious environmental challenge in most part of Lagos State due to extension of residential buildings to flood prone wetlands as population explosion takes the deepest toll on the Nigeria’s foremost industrial centre. The situation is more pathetic for coastal fishing folks who sometimes have their houses built directly on slow flowing waters. This study analyzed utilization of early warning and access to post flood assistance by fishing folks in Lagos. Data were collected with structured questionnaires using simple random sampling. Descriptive Methods and Seemingly Unrelated Bivariate Probit (SUBP) regression were used for data analysis. Results showed that 86.2% of the respondents were males while 69.2% were <40 years old. Also, 72.3% had fishing as primary occupation and 47.9% had <5 years fishing experience. Furthermore, 88.3% had experienced flooding with 13.8% relying on savings as post flood coping method. Only 21.2% had access to warning signals 61.7% never got assistance after flooding. Also, 12.8 and 11.7% of the respondents got assistance from government and associations, respectively. Religious organizations assisted 8.5% while 4.3% got assistance from family members. The SUBP regression results indicated that that being helped during flooding increased the probability of seeking for early warning while being assisted during flooding is only significantly influenced by income (p<0.10). It was concluded that more sensitization on the need to follow media reports about pending environmental hazards like flooding is needed among the fishing folks.
