Climate Change Impacts on Agriculture Production in Enugu State; A Case Study of Uzo Wani LGA
Abstract
The study examined climate change impacts on agriculture production in Enugu state a case study of Uzo Wani LGA. A quantitative survey research design was adopted for this study and Data were collected from 68 farmers in the region using a structured questionnaire. SPSS23 employed to analyze the data. The results showed that farmers in Uzo-Uwani LGA perceived climate change as a significant threat to agricultural production in the region. The major climate change variables identified by the farmers were increasing temperature, decreasing rainfall, and changing rainfall patterns. These variables had significant impacts on crop yield and production in the region. The study found that changing rainfall patterns had a significant negative impact on crop yield, while increasing temperature had a significant positive impact on crop yield. The significant value of the F-statistic was estimated at 0.031 (3.1%), which was less than 5%, leading to the conclusion that there is a significant relationship between climate change variables and agricultural production in Uzo-Uwani LGA, and appropriate adaptation measures can mitigate the impacts of climate change on agricultural production. The study’s findings have important implications for the development of appropriate adaptation strategies and policies in the agricultural sector in Uzo-Uwani LGA and other regions facing similar challenges.
CHAPTER ONE
INTRODUCTION
Background of the Study
Climate change is a global phenomenon that is affecting multiple facets of human life, particularly agriculture. The agricultural sector is becoming increasingly vulnerable to the impacts of climate change as the world’s climate continues to change. Changes in temperature, rainfall patterns, and extreme weather events like droughts and floods are having a significant impact on crop yields and agricultural productivity. According to the Food and Agriculture Organization (FAO) (2021), climate change is one of the main drivers of a decline in global food security, leading to reduced crop yields and increased food prices.
In Nigeria, agriculture is a significant economic activity, accounting for about 22% of the country’s Gross Domestic Product (GDP) and employing about 70% of the population (NBS, 2021). The sector is the main source of food for the population and a significant contributor to rural livelihoods. However, climate change is posing a significant threat to the country’s agricultural sector.
Studies have shown that climate change is already affecting agricultural productivity in Nigeria, with adverse impacts on crop yields, livestock, and fisheries (Majid et al., 2021; Umar et al., 2020). Changes in temperature and rainfall patterns are affecting the timing of planting and harvesting, leading to reduced yields and crop failure in some cases. Extreme weather events such as floods and droughts are also having severe impacts on crop production and livestock.
The impact of climate change on agriculture in Nigeria is a significant concern, given the country’s dependence on agriculture for food and economic growth. It is, therefore, essential to understand the specific impacts of climate change on agriculture in different regions of the country. A case study of Uzo-Uwani LGA in Enugu State can provide insights into the impacts of climate change on agricultural productivity in the region.
Enugu State is one of the states in Nigeria that is highly dependent on agriculture for its economic development. The state is located in the southeastern region of Nigeria and has a population of approximately 3.2 million people. Uzo-Uwani Local Government Area (LGA) is one of the seventeen LGAs in Enugu State. It is a rural area with a population of about 222,278 people, and agriculture is the primary source of livelihood for the people.
Climate change is already having adverse impacts on agriculture in Uzo-Uwani LGA, Enugu State. According to a recent study by Okeke et al. (2021), changes in rainfall patterns, temperature, and extreme weather events such as droughts and floods are affecting agricultural productivity in the region. The study found that the area has experienced a decline in rainfall amount and an increase in temperature over the past few decades. This has led to a decrease in crop yields, with some crops failing to mature due to prolonged dry spells.
Another study by Agwu and Akpan (2020) found that drought is a significant problem for agriculture in Uzo-Uwani LGA. The study reported that drought has led to crop failure and low yields in the area, affecting farmers’ income and livelihoods. The study recommended the adoption of appropriate drought-resistant crops and irrigation methods to mitigate the impacts of drought on agriculture in the region.
In addition to drought, flooding is also a severe problem for agriculture in Uzo-Uwani LGA. According to a recent report by the Nigeria Hydrological Services Agency (NHSA), the area is prone to flooding, with the risk increasing due to climate change (NHSA, 2022). Flooding can lead to soil erosion, loss of crops, and damage to infrastructure such as roads and bridges, affecting agriculture and the overall economy of the area.
Therefore, there is a need to investigate the impacts of climate change on agriculture in Uzo-Uwani LGA and propose appropriate adaptation measures. One possible adaptation measure is the adoption of climate-smart agricultural practices, such as the use of drought-resistant crops, improved water management, and soil conservation techniques (FAO, 2021). Another adaptation measure is the development of early warning systems for extreme weather events such as floods, which can help farmers prepare and mitigate the impacts of these events on their crops and livelihoods.
Statement of Problem
Climate change has been identified as a significant threat to global food security. In Nigeria, climate change is already having adverse impacts on agricultural productivity and food security, with negative consequences for the economy and human well-being. The impact of climate change on agriculture in Enugu State is a significant concern, especially in Uzo-Uwani LGA, where agriculture is the primary source of livelihood for the people.
There is evidence that climate change is already having adverse impacts on agriculture in Uzo-Uwani LGA, as manifested in changes in rainfall patterns, increased temperature, and frequent droughts. These have led to low crop yields, reduced agricultural productivity, and food insecurity in the area. However, there is a lack of adequate information on the specific impacts of climate change on agriculture in Uzo-Uwani LGA and appropriate adaptation measures to mitigate the effects.
Therefore, this study aims to investigate the impacts of climate change on agriculture production in Uzo-Uwani LGA and propose appropriate adaptation measures to enhance the resilience of the agricultural sector to climate change.
