The Effects of Climate Change on Agricultural Productivity in Makurdi, Benue State

CHAPTER ONE

1.0 Introduction

Climate change has become one of the most significant global environmental challenges of the twenty-first century. It affects ecosystems, water resources, and food production systems across the world. In recent decades, changing rainfall patterns, rising temperatures, and increasing frequency of extreme weather events have disrupted agricultural productivity in many developing countries, including Nigeria (Adebayo, 2021). Consequently, climate change poses a major threat to food security and rural livelihoods.

Makurdi, the capital of Benue State, is known as one of Nigeria’s major agricultural hubs, often referred to as the “Food Basket of the Nation.” The region produces crops such as yam, maize, rice, and cassava. However, in recent years, farmers have observed unpredictable rainfall patterns, delayed planting seasons, and declining crop yields. These changes suggest that climate variability is already influencing agricultural output. Therefore, this study investigates the effects of climate change on agricultural productivity in Makurdi to provide practical recommendations for sustainable farming and food security.

1.1 Background to the Study

Agriculture in Nigeria depends heavily on climatic factors such as rainfall, temperature, and humidity. Even slight variations in these conditions can significantly affect crop growth, harvest periods, and soil fertility. Consequently, farmers who rely on rain-fed agriculture are among the most vulnerable to climate change (Eze & Okorie, 2019).

In Makurdi, evidence of climate change is becoming more visible. Rainfall patterns have shifted, resulting in prolonged dry spells or intense rainfall that often causes flooding. Similarly, rising temperatures increase evaporation, reduce soil moisture, and stress crops. These climatic shifts lead to reduced productivity and threaten the livelihoods of small-scale farmers who form the backbone of the local economy.

Furthermore, changes in climate have also contributed to pest outbreaks and soil degradation. Many farmers now struggle to adapt their traditional farming systems to these new realities. Although some efforts have been made to promote climate-smart agriculture, there is still limited data on how exactly climate change affects crop yields in Makurdi. This study therefore aims to fill that gap by analyzing climatic trends and their relationship with agricultural productivity.

1.2 Statement of the Problem

Agricultural productivity in Makurdi has been declining despite the availability of fertile land and abundant water resources. Farmers increasingly report crop failures and lower yields due to irregular rainfall and excessive heat. Although climate change is widely recognized as a contributing factor, there is insufficient empirical research linking climate variability to agricultural output in this area.

Moreover, most local farmers lack access to modern adaptation technologies such as irrigation systems, drought-resistant crops, or weather forecasting tools. Consequently, they continue to depend on outdated farming methods that are highly sensitive to climate fluctuations. This situation threatens food security and income generation in Benue State. Therefore, this study seeks to examine the effects of climate change on agricultural productivity in Makurdi and identify possible adaptation strategies.

1.3 Aim and Objectives of the Study

The main aim of this study is to examine the effects of climate change on agricultural productivity in Makurdi, Benue State.

The specific objectives are to:

1. Analyze climatic trends (rainfall and temperature) in Makurdi between 2010 and 2024.

2. Examine the relationship between climatic variables and crop yield in the study area.

3. Identify the major effects of climate change on agricultural production.

4. Suggest adaptation strategies to improve agricultural resilience in Makurdi.

1.4 Research Questions

1. What are the patterns and trends of rainfall and temperature in Makurdi?

2. How does climate change affect agricultural productivity in the area?

3. Which climatic factors have the most significant impact on crop yields?

4. What adaptation measures can enhance agricultural sustainability in Makurdi?

1.5 Significance of the Study

This study is important because it provides scientific evidence on how climate change affects agricultural production in Makurdi. The results will guide policymakers, agricultural extension officers, and farmers in developing effective adaptation strategies. Furthermore, the findings will assist government agencies in designing climate-resilient agricultural policies and programs for Benue State.

In addition, the research contributes to the broader academic discourse on climate change and food security in sub-Saharan Africa. It highlights the need for integrating weather information, modern irrigation, and soil management practices into rural farming systems. Therefore, this study supports the global goal of achieving sustainable agriculture and environmental resilience.

1.6 Scope of the Study

The study focuses on Makurdi Local Government Area of Benue State. It examines climate variables such as rainfall and temperature and their effects on agricultural productivity between 2010 and 2024. The research covers major farming communities, including Wadata, Agan, and Fiidi. Although it discusses both crop and environmental factors, it does not include laboratory-based soil analysis or livestock productivity.

1.7 Definition of Key Terms

• Climate Change: Long-term alteration of temperature, precipitation, and other atmospheric conditions caused by natural and human activities.

• Agricultural Productivity: The output of agricultural products such as crops and livestock per unit of land area over time.

• Adaptation: Actions taken to adjust practices and systems to minimize the negative effects of climate change.

• Rain-Fed Agriculture: Farming that depends primarily on rainfall rather than irrigation for water supply.

• Sustainable Agriculture: Farming methods that meet current food needs without harming the environment or reducing future productivity.
