The study evaluated socio-demographics, climate change awareness, impact/vulnerability and adaptation for adult residents of Port Harcourt. a purposive random sampling was employed selecting adult participants who had dwelt up to a year in Port Harcourt. 412 questionnaires were distributed. Descriptive statistics, including frequencies and percentages, were generated. Additionally, regression analysis was employed investigating the relationships between independent variables and climate change awareness, adaptation and impact/vulnerability and ANOVA for evaluating the overall fit and significance of regression models. prevalent age groups were 28-37 and 38-47 at (31% and 28% respectively), gender distribution was male (51%) and female (49%), (65%) fall within the educational brackets. largest category of Households size ranged from 6 to 10 members (53.4 %); awareness levels was prevalent at 85% with 60% of awareness attributable to television. 87.9% attributed observable changes in their communities to climate change with most frequencies as shifts in the community rainfall patterns (72.6%) and temperature (63%), whilst a significant 74% did not take any action for adaptation only 35% depended on climate sensitive resources with 65% not believing they or their family members had health conditions impactable by climate change. A significant 74% took no adaptation measures and 57% were uncertain of any community adaptation measures available while 88% had no idea of any government or non- governmental programmes focused on adaptation. overall, a good number had concerns about the future impacts of climate change though many respondents did not feel their communities were prepared enough for future impacts. The study recommends the need for promoting awareness, encouraging responsible behaviours, and establishing resilient infrastructure as critical components of government non-governmental, community and individual response to climate-related challenges as collaborative efforts involving residents, authorities, and relevant organizations are key to fostering resilience and implementing sustainable strategies to tackle the consequences of climate change.

1. INTRODUCTION
Climate change is a pressing global issue that has significant implications for various aspects of society, including the environment, economy, and human health (He, 2017). The impacts of climate change are wide-ranging and can be observed in various regions around the world (Pawełczyk, 2018). To address and mitigate the effects of climate change, it is important to understand the factors that influence individuals’ and communities’ responses and adaptation measures (Devi et al., 2020).
Climate change is a complex issue that requires a multidisciplinary approach to understand and address its impacts (Farida et al., 2017). Factors such as cognitive bias, social discourse, time, money, knowledge, power, entitlements, and social and institutional support all play a role in shaping individuals’ and communities’ responses to climate change (Devi et al., 2020). Effective communication, education, and support systems are crucial in facilitating adaptation to climate change (Terefe, 2022). Furthermore, understanding the economic impacts of climate change and learning from the scientific literature can inform evidence-based policymaking and help mitigate the effects of climate change (Callaghan et al., 2022).
The changing climate in Nigeria is characterized by increasing temperatures, variable rainfall patterns, rising sea levels, and more frequent extreme weather events (Ladan, 2014; Ikumbur & Iornumbe, 2019). These changes have led to adverse effects such as drought, desertification, flooding, and land degradation (Ojomo et al., 2015; Ladan, 2014; Ikumbur & Iornumbe, 2019; Akeh & Mshelia, 2016).
One of the major contributors to climate change in Nigeria is gas flaring, which accounts for approximately 30% of O2 emissions in the country (Afinotan, 2022). Nigeria has the second highest gas flaring level in the world, and this has significant implications for climate change (Afinotan, 2022).
Climate change has significant impacts on the Niger Delta region of Nigeria, which is known for its oil and gas production. The region is considered a climate change vulnerability hotspot (Atedhor & Odjugo, 2022). The adverse effects of global warming, including rising temperatures and sea levels, have had severe consequences for the Niger Delta ecosystem and its inhabitants (Ogele, 2022).
Studies have revealed that the Niger Delta region of Nigeria is only three meter above mean sea level and their coastline is dynamic in nature which renders hundreds of coastal communities exposed and vulnerable to climate change risk and hazards. The region is faced with seasonal flooding, increase in temperature, high precipitation, erosion, river salinization, ocean surges and siltation (Benson, 2020).
The city of Port Harcourt in the South-south region of Nigeria is not immune to these impacts and has been experiencing the effects of climate change, such as increased temperatures, changing rainfall patterns, rising sea levels, frequent flooding, increased incidence of diseases and agricultural disruptions, extreme climate variations have been observed in recent times and many scholarly works have been carried in this area but the challenges still persist, in order to address these challenges, it is crucial to understand the climate change awareness levels, the impact/ vulnerability and adaptation in Port Harcourt, as well as develop effective adaptation and mitigation strategies.
2. LITERATURE REVIEW
Important theories for climate change encompass a wide range of disciplines and perspectives, reflecting the complex and multifaceted nature of the phenomenon. The understanding of climate change involves not only scientific theories but also social, political, economic, and ethical theories. Frankcombe et al. (2010) emphasize the significance of understanding the dominant time scales and processes in climate variability, which is crucial for developing a comprehensive theory of climate change. This highlights the interdisciplinary nature of climate change theories, as they draw from climatology, geology, and oceanography.
the theories of climate change are multifaceted, encompassing scientific, social, political, economic, and ethical dimensions. They reflect the interdisciplinary nature of climate change and the need for comprehensive, integrated theories to address this complex global challenge.
Climate change awareness is a critical aspect of addressing the challenges posed by climate change. It encompasses the public’s understanding of climate change issues, its impacts, and the necessary behavioural and attitudinal changes to mitigate its effects. Research has shown that climate change awareness is influenced by various factors such as education, gender, and accessibility to information (Kousar et al., 2022; Demaidi & Al-Sahili, 2021; Sesay & Kallon, 2022).
The public’s perception of climate change is also an important aspect of climate change awareness. It has been observed that more vulnerable groups, such as those with lower income and education levels, tend to perceive climate change as more consequential and closer, and as a more natural phenomenon than those from less vulnerable groups (Brügger et al., 2021).
The impact of climate change on Port Harcourt can be seen in various sectors, including the environment, public health, and the economy. A study conducted in the Trans Amadi Industrial area of Port Harcourt assessed climate change adaptation, mitigation, and resilience strategies (Wobo & Benjamin, 2018; Nyashilu et al., 2023). The study utilized satellite imagery and field surveys to gather information and identified the inventory of tree species used in urban greening activities. This highlights the importance of implementing strategies to enhance the resilience of urban areas to climate change.
Climate change has significant impacts on various aspects of the environment, society, and economy, leading to increased vulnerability in many regions. Vulnerability to climate change is defined as the degree to which a system is susceptible to and unable to cope with the adverse effects of climate change (Tanny & Rahman, 2017). Research has shown that climate change vulnerability varies across different sectors and regions, with poorer and hotter countries being more susceptible to its negative impacts (Tol, 2020). Vulnerability is influenced by a range of factors, including economic development, social dynamics, and environmental conditions (Grecequet et al., 2017; Lovett, 2015). For instance, studies have indicated that climate change has profound adverse effects on human health, particularly affecting children’s health (Odunola et al., 2018; Sulistyawati & Nisa, 2016). Nigeria is particularly vulnerable to the devastating effects of climate change due to its low coping capability. However, there is a scarcity of studies on the impacts of climate change on health risks in Nigeria. Monday (2019) investigated the effects of climate change on health risks in Nigeria. The study found that climate change-related causes such as increased temperature, rainfall, sea level rise, extreme weather events, and especially increased health risks have led to several direct consequences of climate change.
Okunola et al., (2022) investigated the factors influencing individual and household adaptation strategies to climate risks in Port Harcourt, the key findings underscore a predominant reactive nature in the adopted climate change adaptation strategies, emphasizing the critical necessity for the incorporation of proactive measures such as early warning systems and preparedness initiatives. Additionally, the study revealed that the effectiveness and intensity of adaptation strategies vary based on residential densities within the city, indicating the importance of tailored approaches that account for specific local contexts. Also, low adaptive capacity of rural households in the region has been said to be influenced by factors such as poverty, lack of education, and limited access to alternative livelihood options (Tonbra, 2021).
Efforts to mitigate and adapt to climate change in the Niger Delta have been limited. The adoption of sustainable land management practices and the promotion of renewable energy sources are potential strategies for addressing climate change in the region (Lokonon & Mbaye, 2018). However, there is a need for increased awareness, capacity building, and policy support to facilitate the adoption of these strategies (Ikehi et al., 2022).
The political and regulatory response to climate change and environmental degradation in the Niger Delta has been inadequate (Benson, 2020; “undefined”, 2019). There is a lack of political will and interest among politicians at all levels of government to address the crisis posed by climate change and environmental degradation (Benson, 2020). The failure to enforce strict antipollution laws and the skewed revenue distribution framework have contributed to the perpetuation of environmental degradation in the region (“undefined”, 2019).
3. METHODOLOGY
The research design employs a detailed desktop review of available research publications, materials and other quantitative and qualitative data, building a qualitative case study backed up with primary survey data acquisition. The primary survey entailed the use of survey tools distributed to a sample size drawn from the sample population of the study area and field observation.
The study area covers Port Harcourt, cutting across several communities. Port Harcourt, affectionately nicknamed “Garden City” or “PH City,” is the capital and largest city of Rivers State in southern Nigeria. Located at 4°45′N 7°00′E, (Figure1.) it rests along the Bonny River, placing it at the heart of one of Africa’s richest oil regions.
Port Harcourt boasts a bustling population of over 3 million people, making it the fifth most populous city in Nigeria. Its diverse inhabitants hail from various ethnic groups, including the Ijaw, Ikwerre, Igbo, and Ogoni, contributing to a rich cultural tapestry. Port Harcourt is bordered by other Rivers State Local Government Areas, including Obio/Akpor, Ikwerre, Etche, and Port Harcourt Local Government Area itself.
Fig. 1 Map showing the location of the study area; Port Harcourt.
Rivers State is one of the 36 States of Nigeria, The State falls within the Niger Delta area known as the South-South geo-political zone, with 40 different ethnic groups, and a population of 5,198,716, according to the 2006 Census by the National Population Commission making it the sixth-most populous state in the country.
Data Collection
A total of 412 questionnaires were administered to same sample size (412) the questionnaire contained 28 questions distributed into various sections including Sociodemographic, Climate change awareness, Climate change impact and vulnerability, Climate change adaptation.
Data Sampling
The study employed a purposive random sampling procedure in the selection of respondents for the study a method chosen to eliminate bias and ensure that each member of the population had an equal chance of being selected. The choice of purposive sampling technique was to select participants who were residents of Port Harcourt, had dwelt up to a year and more in Port Harcourt and were adults above the age of 18 the aim of the purposive sampling was to capture only the perspective of adults who had experienced a longer period of climatic conditions. This approach guarantees a fair representation of the various demographic, socio-economic, and geographic perspective of adult residents who had dwelt a year and more in Port Harcourt. By distributing 412 questionnaires using this method, the study seeks to capture the heterogeneity of the population’s experiences and perspectives regarding climate change.
The Taro Yamane’s formula (Yamane, 1967) was used to come up with an appropriate sample size for the study with five percent (5%) significance level.
n=N/ (1+N (e^2)) where:
n = sample size N = population e = significance level (0.05)
Thus
n = 963,373/ (1+963,373 (0.05^2))
n = 963,373/ (1+963,373 (0.0025))
n = 963,373/ (1+2,408.4325)
n = 963,373/2,409.4325
n = 400
This resulted to a sample size of 400, though 412 respondents were sampled for the primary survey this is because it is not out of place since a sample that is larger than the exact sample size will be a better representative of the population and will hence provide more accurate results.
To collect primary data, a structured questionnaire was designed, encompassing a range of variables to facilitate a comprehensive analysis. The questionnaire included sections addressing climate change awareness, adaptation strategies, resilience measures, and demographic information (such as age, gender, education level, household size, and occupation). The inclusion of these variables allows for a nuanced exploration of how socio-demographic factors may influence individual responses to climate change.
Data Analysis
ANOVA (Analysis of Variance) was performed to evaluate the overall fit and significance of the regression models. This statistical approach adds robustness to the analysis, allowing for a more comprehensive understanding of the selected factors (variables) influencing climate change awareness, impact/vulnerability and adaptation in the study area.

Statistical Regression Analysis of the Primary Survey.
i. Climate Change Awareness: Tables 5-7 showthe regression statistics, Anova and model results for climate change awareness (the dependent Variable) and Age, Gender, Education Level, Household Size and Occupation (the Independent Variables).
The Multiple R value is 0.2188, suggesting a weak positive correlation between the independent variables and climate change, the R-squared value from the regression statistics of climate change awareness (0.0479) indicates that approximately 4.79% of the variance in climate change can be explained by the combined influence and suggests that the model explains a relatively small proportion of the variance in climate change awareness, indicating that other factors not included in the model may also be influencing the outcomes. The ANOVA table 4.54 suggests that there is a statistically significant relationship between the independent variables (age, gender, education level, household size, and occupation) collectively and the dependent variable (climate change awareness). The low p-value (0.001259394) associated with the F-statistic indicates that at least one of the independent variables in the model is contributing significantly to explaining the variability in climate change awareness.
Looking at the individual predictor coefficients to understand which specific variables are driving this relationship, overall education level and household size have statistically significant relationships with climate change awareness with p-values of 0.005 and 0.008 respectively in this model, while age, gender, and occupation do not.
ii. Climate Change Impact and Vulnerability: Tables 8-10 showthe regression statistics, Anova and model results for climate change impact and mitigation (dependent variable) and changes in temperature, changes in rainfall pattern, changes in relative humidity, Respondents dependence on Climate-Sensitive Resources or Industries? (e.g., Agriculture, Fishing, Forestry), Respondent or family members of respondents having any health conditions that could be exacerbated by Climate Change? (e.g., Respiratory Issues, Cardiovascular Problems) (Independent variables).
The regression statistics suggest that there is a moderate to strong relationship between the predictor variables and the climate change vulnerability assessed. The R squared value indicates that around 51.38% of the variability in vulnerability can be explained by the independent variables in the model. The adjusted R-squared considers the model’s complexity and suggests that approximately 50.78% of the variability is explained.
The Anova result presents a large F-statistic value, with an extremely small associated p-value is, suggesting that the model is a good fit and that the independent variables collectively have a significant impact on explaining the climate change vulnerability being assessed.
the statistical significance of the specific variables in the model using p-values showed changes in temperature, changes in rainfall pattern and changes in relative humidity with p-values of 3.01E-12, 1.5E-33 and 0.010103 respectively to have high significant impact on climate change vulnerability as their p-values were close to 0 (zero).
iii Climate Change Adaptation: Tables 11-13 showthe regression statistics, Anova and model results for climate change adaptation (Dependent Variable) and Climate resilient house, Renewable energy adoption, Water management, whether there are any existing Community-Based Adaptation Measures in place, whether respondents are aware of any Government or Non-Government programs focused on Climate Change Adaptation, how concerned respondents are about the future impacts of Climate Change in their community (the independent variables).
The multiple R value for the regression statistics for climate change adaptation, (0.5218) suggests that there is a moderate positive correlation between the predicted and observed values. R² value of 0.2723 indicates that approximately 27.23% of the variability in the dependent variable is explained by the independent variables included in the model. This means that the model is accounting for a significant portion of the variability, but there are other factors not included in the model that also influence the dependent variable.
The F-statistic is quite high (25.25904), and the associated p-value (1.7544E-25) is extremely low. This suggests that the variability explained by the regression model is significantly greater than what would be expect by chance alone.
Overall, for statistical significance of specific variables, climate resilient house, renewable energy adoption, water management, Community-Based Adaptation Measures and concern about future impacts of Climate Change have statistically significant effects on the dependent variable with p-values of (1.21E-06), (4.24E-05), (2.13E-07) and (0.003261) and (0.000389) respectively. However, Government/Non-Government Programs is not statistically significant in this model with high p-value of (0.9178).

DISCUSSION OF FINDINGS
The most prevalent age groups were 28-37 and 38-47, comprising a significant portion of the respondents (31% and 28% respectively), studies have shown that younger generations are more likely to be concerned about climate change and express a higher level of awareness and interest in climate-friendly behaviours (Petrescu-Mag et al., 2023; Korkala et al., 2014). The gender distribution in the survey demonstrated a balanced representation of male (51%) and female (49%) respondents though with males slightly higher, gender has been said to play a crucial role in climate change adaptation and awareness, gender dimensions in the context of climate change adaptation in coastal communities have shown that gender influences factors such as asset risk and livelihood risk perceptions (Graziano et al., 2018). Three categories of education levels (SSCE/O-Level, Degree or HND & A-Level/Higher/BTEC) had made up most of the responses, accounting for about 65% of the total participants, this is indicative of the fact that a significant portion of the respondents fall within these educational brackets, education has been identified as a key factor in understanding and employing adaptation strategies for climate change and unpredictability (Megabia et al., 2022). Households with a size ranging from 6 to 10 members were the largest category (53.4 %), this observation indicated that a significant portion of families within the community had relatively larger household sizes. Larger households have been noted to have implications for resource consumption, energy usage, and communal dynamics, potentially influencing the strategies and challenges related to climate change resilience. Ahmed & Alam (2015) in Bangladesh found that larger households faced greater challenges in dealing with climate change due to higher resource needs and lower per capita income. Household size has also been found to impact awareness of climate change effects, with larger household sizes being more vulnerable to adverse effects such as reduced agricultural production and food shortages (Ibrahim et al., 2015). Individuals who had lived in Port Harcourt for more than 10 years (66%) constituted the largest group. This significant percentage indicated a substantial portion of long-term residents who likely had deep ties to the community. A study in Chile by Fernandez et al., (2015) have shown that long-term residents tend to perceive more significant climate change over time compared to newcomers.
It is noteworthy that majority of respondents (85%) had heard about climate change, which indicated a relatively high level of awareness on climate change, however, a notable proportion (15%) of respondents had still not heard about climate change. This majority proportion indicates that a substantial segment of the population is indeed conscious of the potential consequences that climate change could bring to their community. The prevalence of climate-related content in television programs, played a significant role in spreading awareness on climate change followed by other media this agrees with (Ju & Jo 2021) who also identified the sources of information through which rural farmers received information on climate change, including personal observation, friends, radio, and television.
The references to changes in weather patterns, increased rainfall, and partial flooding suggested broader alterations in climatic conditions, potentially affecting the community’s susceptibility to extreme weather events and the capacity to manage water-related challenges. A significant majority (84.7%) had indicated noticing changes in their community attributable to climate change, with the most reported frequency as shifts in the community rainfall patterns (72.6%) and temperature, (63%) this substantial percentage underscores the fact that a significant portion of the community perceives climate change as a tangible factor influencing their local environment. This result is in line with the reports of (Stanley et al., 2021) that had high percentage (85-93%) of respondents who had perceived climate change impacts in their community and Ojo et al., (2019) in their study among fishing communities in the Niger Delta, who found that 98% of respondents perceived changes in climate variables like rainfall patterns, temperature, and sea level rise. The most reported impacts as direct results of these changes were extreme cold, heatwaves and flooding.
On the dependence on climate sensitive resources respondents’ perception had suggested that some individuals had recognized a certain level of reliance on sectors such as agriculture, fishing, or forestry, but this dependence hadn’t been absolute as 37% went for “Partially” and 35% “Yes”. Though a study by Onwumodu and Chukwu (2020) found that 85% of respondents relied on climate-sensitive sectors like agriculture and fishing.
Majority of respondents had expressed (“No” 65%) that they didn’t believe that they or their family members had health conditions that might have been worsened by climate change Impact, this perspective suggests that most individuals perceived their health conditions or those of their family members to have been relatively unaffected by changing climatic conditions. Nwaogu and Agunwoke (2020) in neighbouring Imo and Rivers States mentioned limited understanding of health impacts, potentially aligning with the “No” category while the study of Ajaegbu et al. (2015) reflects the (“Not Sure” 19%) category as it mentions limited awareness about specific health impacts. The study of Ebi et al. (2017) which focused on the Niger Delta, highlighted the potential for climate change to worsen existing health conditions aligning with the (“Yes”16%) category of this study.
On climate change adaptation, majority of respondents (74%), had indicated that they or their household hadn’t taken any specific measures to adapt to the impacts of climate change while only 26% did take measures that include the use of renewable energy, climate resilient houses and water management related measures. Low adaptive capacity of rural households in the region has been said to be influenced by factors such as poverty, lack of education, and limited access to alternative livelihood options (Tonbra, 2021).
A good number of respondents (59%) were not sure of any existing community-based adaptation measures in place while some others (28%) believed there were none, this uncertainty could be said to indicate a lack of awareness about such initiatives, potentially pointing towards a need for increased communication and education about community-based adaptation efforts, only 13% were aware of some community initiatives. While for government and non-governmental initiatives a significant 88% were not aware of programmes focused on climate change adaptation, This significant percentage suggests a widespread lack of awareness about initiatives that are specifically aimed at addressing the impacts of climate change and building resilience within the community this corroborates with (Oramah & Olsen, 2021) whom though stated that vulnerability of Nigeria to climate change has led to efforts by the government to develop adaptation and mitigation strategies also noted that institutional capacity for climate change adaptation at the federal, state, and local government levels were still weak. Though with varying levels of concern, overall, a good number of respondents have concerns about the future impacts of climate change in their region. Likewise varying levels of the perceived community preparedness to tackle future climate change impacts; many respondents did not feel their community was prepared for future impacts of climate change.
The individual predictor coefficients to understand which specific variables were driving the relationship between Climate change awareness and the independent variables, overall education level and household size have statistically significant relationships with climate change awareness with p-values of 0.005 and 0.008 respectively in the regression model, while age, gender, and occupation were not statistically significant.
For climate change impact and vulnerability, the statistical significance of the specific variables in the model using p-values showed changes in temperature, changes in rainfall pattern and changes in relative humidity with p-values of 3.01E-12, 1.5E-33 and 0.010103 respectively to have high significant impact on climate change vulnerability as their p-values were close to 0 (zero).
For climate change adaptation Overall, for statistical significance of specific variables, climate resilient house, renewable energy adoption, water management, Community-based adaptation measures and concern about future impacts of climate change had statistically significant effects on climate change adaptation with p-values of (1.21E-06), (4.24E-05), (2.13E-07) (0.003261) and (0.000389) respectively. However, Government/Non-Government Programs was not statistically significant with p-value of (0.9178).
CONCLUSION AND RECOMMENDATIONS.
This study reflects individuals and community’s challenges and opportunities in the face of climate change impacts. These underscores the necessity of promoting awareness, encouraging responsible behaviours, and establishing resilient infrastructure as critical components of government, community and individual response to climate-related challenges.
Although the survey recorded high awareness level of Climate change, many respondents still do not know what the impacts of climate change are though a good number of respondents are aware it is worthy of note that a good number of persons within the sample population relative to the sample size may not be aware of climate change as well as its impact.
likewise, a very low awareness level was recorded for government and non-government initiatives geared towards adaptation and resilience to climate change impact. If this initiatives exist in communities better awareness needs to be created as high percentage of respondent agreed to have heard about climate change via predominantly television and other media platforms same avenues could be utilised by the appropriate authorities to propagate and spread climate change adaption and resilience initiatives, many communities are also not prepared for future outturn of events that may exacerbate the impact of climate change, it is important for the government, local authorities, communities as well as individuals to play an active role in the fight for survival against climate change impact.
Collaborative efforts that involved local residents, authorities, and relevant organizations are key to fostering resilience and implementing sustainable strategies to tackle the consequences of climate change. Integrating climate change into policy processes and improving climate science education can enhance the effectiveness of adaptation and mitigation efforts to reduce the effect of climate change.
