The Impact of Climate Change on Cassava Production in Nigeria

Chapter One

1.1 Background of the Study

Cassava (Manihot esculenta) is one of the most important staple crops in Nigeria. It provides carbohydrates, serves as a source of income for smallholder farmers, and is used in industrial products such as flour, starch, and bioethanol. Nigeria is the largest cassava producer in the world; however, its productivity faces serious threats from environmental challenges. Specifically, climate change has affected rainfall patterns, temperatures, and the frequency of extreme weather events (FAO, 2021).

Moreover, climate change leads to unpredictable rainfall, prolonged dry seasons, and occasional flooding. These factors disrupt cassava growth and reduce tuber size, quality, and overall yield. Although cassava is relatively resilient, extreme weather conditions can significantly affect its development. Research has shown that rising temperatures and irregular precipitation negatively influence root formation and starch accumulation (Akinbile & Akinyemi, 2020).

Furthermore, farmers in Nigeria rely heavily on rain-fed agriculture. Therefore, they are highly vulnerable to climatic variability. In addition, climate change can increase pest and disease prevalence, which further reduces productivity. Consequently, understanding the effects of climate change on cassava production is essential. This knowledge can help farmers adopt strategies that improve resilience and ensure sustainable yields.

1.2 Statement of the Problem

Despite the importance of cassava to food security, farmers face increasing challenges due to climate change. Erratic rainfall, rising temperatures, and extreme weather events have led to reduced yields. In addition, many farmers lack access to climate-resilient cassava varieties, irrigation facilities, and information on adaptation practices. As a result, production losses continue to threaten both livelihoods and food security. Therefore, it is necessary to examine how climate change impacts cassava production and identify measures to enhance productivity under changing conditions.

1.3 Objectives of the Study

The main objective of this study is to assess the impact of climate change on cassava production in Nigeria.
Specifically, the study aims to:

1. Examine how temperature and rainfall variability influence cassava growth and yield.

2. Identify the challenges faced by farmers due to climate change.

3. Evaluate the adaptation strategies employed by farmers to mitigate climate impacts.

4. Recommend practical measures to improve cassava productivity under changing climatic conditions.

1.4 Research Questions

1. How do temperature and rainfall variability affect cassava growth and yield in Nigeria?

2. What challenges do cassava farmers face as a result of climate change?

3. What adaptation strategies are currently used by farmers to cope with climate change?

4. How can cassava production be improved despite changing climatic conditions?

1.5 Significance of the Study

This study is significant because it provides insights into the effects of climate change on cassava production. Therefore, farmers can adopt better practices to prepare for climatic challenges. Moreover, policymakers can use the findings to design climate-smart agricultural policies that promote sustainable production. In addition, researchers and students will benefit, as the study adds to the body of knowledge on cassava resilience and adaptation strategies. Ultimately, improving cassava production in the face of climate change will enhance food security and farmer income in Nigeria.

1.6 Scope of the Study

The study focuses on cassava farms in selected Nigerian states where climate variability is most pronounced, including Benue, Ogun, and Cross River States. It will assess the relationship between rainfall, temperature, and cassava yield. In addition, the research will examine adaptation strategies such as irrigation, crop diversification, and the use of climate-resilient cassava varieties.

1.7 Definition of Key Terms

Climate Change: Long-term alterations in temperature, precipitation, and weather patterns caused by natural and human activities.
Cassava Production: The cultivation, harvesting, and processing of cassava tubers for food and industrial use.
Yield: The total quantity of cassava harvested per hectare of farmland.
Adaptation Strategies: Techniques or methods used by farmers to reduce the negative effects of climate change.

1.8 Organization of the Study

The study is structured into five chapters. Chapter One introduces the research, presenting the background, problem, objectives, and research questions. Chapter Two reviews relevant literature on climate change and cassava production. Chapter Three explains the methodology. Chapter Four presents data analysis and discussion, while Chapter Five concludes the study and provides recommendations.
