LITERATURE REVIEW
Conceptual Review
The Concept of Climate Change
Climate change is a complex phenomenon that has been the subject of intense research and debate over the years. The Intergovernmental Panel on Climate Change (IPCC) defines climate change as “a change in the state of the climate that can be identified (e.g., by using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer” (IPCC, 2021). Climate change can result from natural causes, such as volcanic activity, solar radiation, and changes in the Earth’s orbit, as well as human activities, such as deforestation, burning of fossil fuels, and industrial processes (IPCC, 2021).
The impacts of climate change are widespread and affect various aspects of human life, including health, food security, water resources, and economic development (World Bank, 2021). According to the IPCC (2021), the Earth’s average surface temperature has increased by about 1.1°C since the pre-industrial era, and this warming trend is expected to continue. The increasing concentration of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, in the atmosphere is the primary cause of global warming (IPCC, 2021).
The impacts of climate change are already being felt in many parts of the world, with more severe effects expected in the future (UNEP, 2021). The changing climate has resulted in changes in temperature, rainfall patterns, and extreme weather events, such as droughts, floods, and hurricanes (IPCC, 2021). These changes have had significant impacts on natural ecosystems, human health, and economic systems (IPCC, 2021).
The agricultural sector is highly vulnerable to the impacts of climate change, as it is dependent on climatic factors such as temperature, rainfall, and soil moisture for crop production (FAO, 2021). Changes in these factors can result in reduced crop yields, crop failure, and food insecurity (FAO, 2021). Climate change has also resulted in the spread of pests and diseases, which have affected crop productivity in many parts of the world (FAO, 2021).
The impacts of climate change are not limited to the agricultural sector alone. The changing climate has resulted in changes in sea levels, ocean acidity, and ocean currents, which have had significant impacts on marine ecosystems (IPCC, 2021). The melting of glaciers and ice caps has resulted in rising sea levels, which pose a significant threat to low-lying coastal areas and small island nations (IPCC, 2021). The changing climate has also resulted in changes in weather patterns, such as the frequency and intensity of heatwaves, droughts, and hurricanes, which have affected human health and wellbeing (WHO, 2021).

RESEARCH METHODOLOGY
Research Design
The research design refers to the overall plan or structure of a research study that outlines the methods and procedures for collecting and analyzing data. The research design is a critical component of any study as it determines the reliability and validity of the findings. In this study, the research design adopted is a quantitative survey research design.
A quantitative survey research design is a type of research design that involves the collection of numerical data that can be analyzed using statistical methods. This type of research design is commonly used in social science research as it allows for the collection of a large amount of data that can be analyzed to generate statistical inferences about the population. According to Creswell (2022), a quantitative research design is used to investigate relationships among variables and to test hypotheses.
The justification for using a quantitative survey research design in this study is that it is suitable for studying the impacts of climate change on agriculture production in Enugu State. The design allows for the collection of data from a large population that can be analyzed to generate reliable and valid results. Additionally, a survey research design is appropriate for collecting data on people’s attitudes, beliefs, and behaviors regarding climate change impacts on agriculture production.
The survey research design can be administered using various methods such as online surveys, paper surveys, and telephone surveys. In this study, a paper survey will be administered to the respondents. This method was chosen because it allows for the collection of data from a diverse group of respondents, including those who may not have access to the internet. Additionally, paper surveys have a higher response rate compared to online surveys (Babbie, 2023).
Population of the Study
Population of the study refers to the entire group of individuals, objects, or events that share similar characteristics and are of interest to the researcher (Creswell, 2022). It is the group of individuals from which the sample is selected, and the findings of the study are generalized (Polit & Beck, 2022). The population of the study should be clearly defined in the research methodology to ensure that the study’s findings are applicable to the target population (Houser, 2023). In this study, the population of interest is the farmers in Uzo-Uwani Local Government Area (LGA) of Enugu State, Nigeria, who are engaged in agriculture production. The target population is estimated to be 800 farmers who are registered with the Uzo-Uwani Local Government Agricultural Development Program (ADP).

SUMMARY OF FINDINGS, CONCLUSION AND RECOMMENDATIONS
Summary of Findings
Climate change is a global phenomenon that has been widely recognized as a significant threat to agricultural production worldwide. This study focused on the impacts of climate change on agricultural production in Uzo-Uwani Local Government Area (LGA), Enugu State, Nigeria. The study aimed to identify the major climate change variables affecting agricultural production in Uzo-Uwani LGA, examine the impacts of climate change on crop yield and production, and propose appropriate adaptation measures to mitigate the impacts of climate change on agricultural production.
To achieve these objectives, a questionnaire survey was conducted among 68 farmers in Uzo-Uwani LGA. The survey was designed to collect data on farmers’ perceptions of climate change, its impacts on crop yield and production, and the adaptation measures being used to cope with its effects. The data collected were analyzed using descriptive statistics, correlation analysis, and regression analysis.
The impact of climate change on agricultural production has become a major concern for farmers in Uzo-Uwani LGA, as revealed in a recent study. The study aimed to identify the key climate change variables that are affecting agricultural production in the region, and to assess their impact on crop yield.
The findings of the study indicate that farmers in Uzo-Uwani LGA perceive climate change as a significant threat to their agricultural production. The major climate change variables that were identified by the farmers were increasing temperature, decreasing rainfall, and changing rainfall patterns. These variables have significant impacts on crop yield and production in the region.
One of the most significant climate change variables identified by the farmers was the increasing temperature. The study found that the increasing temperature has a significant positive impact on crop yield in the region. This is because the increased temperature promotes the growth and development of crops, resulting in higher yields. However, it is important to note that the positive impact of increasing temperature is limited by other factors such as water availability and soil fertility.
On the other hand, the changing rainfall patterns were identified as having a significant negative impact on crop yield in the region. The study found that the changing rainfall patterns have a significant impact on the timing and amount of rainfall, which in turn affects crop yield. This is because crops require a certain amount of water at specific stages of their growth, and any deviation from this requirement can have a negative impact on crop yield.
The decreasing rainfall was also identified as a key climate change variable that is affecting agricultural production in the region. This is because rainfall is essential for crop growth and development, and a decrease in rainfall can lead to reduced crop yields. In addition, the decreased rainfall can also result in reduced soil moisture, which can lead to increased soil erosion and reduced soil fertility.
The study highlights the need for farmers in Uzo-Uwani LGA to adopt appropriate adaptation strategies to mitigate the negative impact of climate change on their agricultural production. One of the key adaptation strategies is the adoption of climate-resilient crops that are able to tolerate the changing climate conditions. Another important adaptation strategy is the adoption of sustainable land management practices that can help to conserve soil moisture and fertility, and reduce soil erosion.
The study also found that the impacts of climate change on agricultural production in Uzo-Uwani LGA are significant and widespread. The impacts include reduced crop yield, increased pest and disease incidence, soil erosion, and loss of soil fertility. These impacts have resulted in reduced income and food insecurity for farmers in the region.
To mitigate the impacts of climate change on agricultural production in Uzo-Uwani LGA, the study proposes appropriate adaptation measures. These measures include the promotion of climate-smart agriculture practices such as the use of drought-resistant crop varieties, conservation agriculture, and agroforestry. The study also recommends the development of water harvesting and storage facilities, the provision of early warning systems for extreme weather events, and the establishment of community-based climate change adaptation plans.
Consequently, this study highlights the significant impacts of climate change on agricultural production in Uzo-Uwani LGA, Enugu State, Nigeria. The study identified the major climate change variables affecting agricultural production in the region and proposed appropriate adaptation measures to mitigate its impacts. The study recommends that policymakers and other stakeholders should take urgent action to implement these adaptation measures to ensure the sustainability of agricultural production in the region.
