Abstract
Climate variability and change affect many coastal settlements, islands and lowland countries as result of sea level rise (SLR). Mombasa, an island is a coastal settlement in Kenya coastal region with inhabitants of about 1.2 million. It hosts East Africa’s largest seaport. It is a major tourist destination along the Indian Ocean. As a coastal settlement, Mombasa had experienced several flooding in past decades due to climate variability and change. Its increasing population and fast urbanization have exposed the area to flood related hazards. Consequently, three mostly flooded towns: Kisauni, Nyali and Changamwe in Mombasa were surveyed to access the role of indigenous knowledge in mitigating climate change induced flooding impacts on human settlements and livelihoods and to enhance adaptation. The study used binary logistic regression (BLR). Primary data were obtained using open ended questionnaire randomly amongst residents using Likert IQ scale. Secondary metrological data were obtained from the Kenya Metrological Department. It was found that low environmental education and climate change awareness on sea level rise are the main reasons for low community preparedness and less adaptation plans. Also, tourism and commercial activities contribute to the lower local community’s efforts to climate change adaptation action plan. It can be concluded that in order to achieve national efforts to mitigate impacts and enhance boost climate change adaptation and resilience in Mombasa, local and national governments and their including partners ought to excite more supports to Kenya’s National Adaptation Action Plans by increasing science based environmental education, public awareness and integrating county specific climate change adaptation polices into national education system and construction framework that provides sustainable alternatives to overreliance of sea wall to protect Fort Jesus and other historic and tourist attraction sites naturally based resources and enhance conservation.

Introduction
Climate change, a phenomenon attributed critically to human activities resulting to emission of greenhouse gas that alters global mean temperature and its momentous impacts on local and global climate systems that drive lives [1]. Despites the many national and international climate sensitive policies, resolutions, and aggressive industrial switch-green revolution, the targeted 20 C in reduction mean global temperature towards minimizing impacts of climate change seem unlikely [2]. Although mitigation of greenhouse gas (GHG) is highly required to reduce increasing global warming impacts, but the present sea level rise trend will continue to the next century as result of previous emissions [3]. It’s predicted that by 2100, the probable impacts of climate change projects will occur concurrently if global emission trend is cut by thrice its present level [4].
There are several studies and reports on Sea Level Rise and its impacts on coastal communities as result of climate change and climate variability. It is predicted that the impacts of sea level rise due to climate variability in coastal Kenya using simulation and digital elevation model (DEM) will be high. It’s estimated that by 2050, about 577,000 people within low lying coastal areas including assets worth of $5.8 billion will be exposed [5].
Though coastal zone provides enormous ecosystem services and attracts high inflow of people; though, they may be exposed to climate change induced flooding-sea level rise (SLR) [6]. Global efforts are required to mitigate impacts of flooding, particularly in lowland coastal settlements [7]. Impacts of coastal flooding and adaptation costs as result of SL in this 21th century are evaluated universally in view of varying continental data, demography, adaptation approaches and socioeconomic development [8]. The impacts vary according to local climate, geology and anthropogenic activities. In many parts of Africa, owing to low advances in technology and under-capacity institutions, there is little data on climate variability, climate change and SLR [9,10] Increasing mitigation measures and adapting to climate change will increasingly reduce impacts of climate-induced flooding and restore climate stability [11].
In coastal areas, climate change related flood impacts could be pronounced as result of SLR. This increases probability of property damage due to inundation, erosion, high waves, loss of beaches and recreation centers including ecologically important wetlands [12]. Further impacts include damage of public infrastructures such as wastewater treatment facilities, low-lying roads, piers/ports, and facilities located on coastal bluffs. Combined efforts are needed to mitigate these climate related impacts. This includes but not limited to: risks management, access to adequate climate data and information, sizable human resource, advanced technology, and finances [13]. In Kenya, increased mean air and sea temperature, sea level rise and extreme weathers are amongst the projected impacts of climate change and variability; these projections have begun impacting socioeconomic strata and the national environment [14]. Increase in sea surface temperature and marine biological invasion such as invasive species and harmful algal blooms affect coral reef ecosystem. Consequently, this would negatively impact the livelihoods of millions of people in the coastal region who are dependent on that ecosystem for food, income, and shoreline defense.
Notwithstanding, understanding (sound environmental education) of localized anthropogenic activities and climate change is key to formulating climate change resilience, adaption and mitigation measures for local communities in coastal areas [15]. Review has made known that climate change education is paramount to the developments of effective intervention measures [16]. Outbreak of infectious diseases, flashing flood and increase in cost of basic commodities would more be pronounced due migration of people in informal coastal settlements in sub-Saharan in Africa [17]. In Kenya, study showed that Integrated Coastal Management (ICM) policy tailored from the National Adaptation Plan (NAP) is gapped in some counties including human capacity gap, financial stress and limited access to climate change information [18]. As supported by this study, other studies [19-22]. The sound environmental knowledge, governance and management (environmental education) are principal tools to climate change adaptation and mitigation.
Methodology
The study was conducted in five wards: Junda, Bamburi, Magongo, Kisimani and Port Reitz within three constituencies of Kisauni, Nyali and Changamwe all in Mombasa County, Kenya. Structured and semi-structured questionnaire were administered to assess level of awareness and environmental education amongst permanent residents of Mombasa on climate variability and change .Three hundred seventy-one (371) respondents were interviewed, i.e., 99, 59, 66, 69, and 74 in Junda, Bamburi, Magongo, Kisimani, and Port Reitz, respectively. The sample was determined using Yamane equation [23].
Where n =the sample size, N=the population size and e=the acceptable sampling error and *95% confidence level, P=0.05 assumed. Secondary climate data were obtained from Kenya Metrological Department Mombasa substation, Moi International Airport. The data was used to correlate with primary field data using SPSS, version 23.0 [24]. One hundred ninety-nine females, 54% and one hundred seventytwo males, 46%, including heads of family and household participated views were evaluated (Table 1).

Binary Logistic Regression (BLR) was used to test the hypothesis to ascertain statistical significance of variables [25]. For example, BLR model for role environmental education to indigenous knowledge of flood prediction/forecast
Where, P is the probability of the chance/event (Environmental Education), (1-P) is the probability of either of the chances, B2 is the constant for role of environmental education and X2 is the role of environmental education variable. In this model, the H1 (alternative hypothesis) that low environmental education significantly influences indigenous’ means to mitigate and adapt to flooding and climate variability and change was statistically significant, P-value < 0.05 (Table 2.). Correspondingly, at least one independent variable was statistically significant, hence, H1 was accepted. From Equation 1, the constant for the above case was -0.312. Statistical significance of Wald’s test of likelihood was used [26].

Results
As shown in (Figure. 1) below, there were 371 respondents, 54% females and 46% males; 50% adults and 44% youth. It was found that 21% and 74% of participants completed primary education and beyond respectively. Of these, 69% has household size of 1 to 5 persons; 54% are formerly employed in public and private sectors; while 44% are involved in agriculture, low capital-intensive business and tourism.
In spite of the level of former education amongst respondents, it was found that there is low environmental education and awareness on climate change-induced flooding (Figure. 2) This could be as result of dependence on unscientific climate forecasting by local/indigenous means that is profoundly infiltrated by urbanization and influx of people interfering with local climate indicators. In addition, there is also interference with intense socioeconomic activities, tourism and port commerce. Similarly, there is low community awareness on climate change and related impacts and consequently lower community adaptation plan except through government (Figure. 3) Hence, disturbing socioeconomic impacts of climate changeinduced flooding and sea level rise is very likely on residents’ income and livelihoods.
Discussion
Mitigating and adapting to climate change induced flooding impacts depends on crucial environmental education and awareness through timely scientific weather forecasts [27]. It has been reported that many disaster prevention and mitigation policies rarely address gender, [28] while women are more likely to have higher consequences [29]. Thus, formal levels of education of respondents were accessed (Figure. 4) more females, 54% participated than men, 46%.
Despite the level of formal education of respondents (Figure. 5) 38% of participants still depend on local indigenous knowledge and observation, while 34%, depend on weather forecasts on televisions and radios (Table 3). Others depend on Baraza (palaver hut discussion); hence, many depend on local indigenous knowledge and personal experience to forecast weather as agreed by Adebayo K et al. that is basic observation and experience of rural settlers increase their knowledge about flooding [30]. However, the growing portability of media devices and their accessibility is increasing information dissemination digitally.

Table 3: Reliability of respondents' prediction on the occurrence of flooding in their communities
As stated above, low environmental education and climate change awareness as well as loss of local settlements (indigenous communities) to urbanization, knowledge on climate variability and change has expressively reduced amongst locals resulting to inconsistent predictions of flood and its related environmental hazards (Table 4). This shows that individual’s experience and observation are not dependable. This is consistent with that notable past flood events are mostly factors individuals use to predict future flood occurrence but such prediction may not specify the extent and magnitudes of floods they had experienced [31]. Accordingly, irregular rainfall patterns shown in KMD data (Figure. 6) support our finding that locals’ prediction may be unreliable as the changing climate brings newer flood experiences. This validates finding of World -Wide Fund for Nature that long wet season contributes more annual precipitation than short wet season in East Africa attributable to agriculture, deforestation, beach sand mining, overfishing, and grazing. These anthropogenic activities interfere with indigenous knowledge system of environmental changes as reported by that precision of flood prediction by local communities has reduced due to vulnerability to climate change [32].

It was found also that females have lower indigenous knowledge on flood prevention and mitigation compared to their male counterparts, 47% and 53%, respectively; this has been reported in other studies, that women’s ability to respond to flood is lower compared to men and their capacity to participate in flood management is low [33-36].
Likewise, many adults, 44% lack evidence of indigenous knowledge to predict and mitigate flood compared to youth, 37%; and yet 7% of youth have indigenous knowledge on flood prediction and mitigation measures than adults, 6% and vice versa. Notwithstanding, more adults (50 years and above) were targeted by this study, considering that long life comes with more experience and understanding of indigeneity. But this study found the contrary, however, it agrees with that indigenous knowledge lacks accountability within communities; and disagrees with that the lack of accountability is prevalent among the youth [37]. Also, 54% of participants believed lack of fitting drainage system, weak enforcement of zoning laws and poor waste management are the principal causes of flooding contrary to sea level rise and its associated factors. This finding confirms studies by Brody et al. and Douglas et al that high precipitation causes flooding; nonetheless, fast urbanization and poor environmental planning adversely facilitate occurrence and severity of flooding.
Conclusion
In effect, climate variability and change occur in Mombasa as evidenced by KMD rainfall data. High precipitation and sea level rise are significantly contributing to flooding in the study communities. Low environmental education, climate change awareness and unempirical weather forecast increase socioeconomic impacts of climate-induced flooding and as well lower climate change mitigation and adaptation efforts.change and variability occur in Mombasa. It has been, to some extend manifested by rising sea levels contributing to flooding. Anthropogenic activities and low climate knowledge are the fulcrum to the observable impacts. Hence, more attentions are needed to locally achievable policy drive and framework that supports the NAP and other global efforts. The framework must address sustainable alternatives to coastal socioeconomic reliance such as tourism, fishing and urbanization. Immediate interventions may include county specific climate-framework; nationalization of climate-based science education and improve local communities’ resilience through conservation of non-renewable coastal resources.
