Project – Economic Analysis of Climate Change Adaptation Strategies and Their Effects on the Productivity and Profitability of Broiler Production Enterprises in Southwestern Nigeria

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Agriculture remains one of the most important sectors of the Nigerian economy, contributing significantly to food production, employment generation, poverty reduction, and rural development. The livestock subsector, particularly poultry production, plays a critical role in enhancing food security through the provision of affordable animal protein and income for millions of households. Among poultry enterprises, broiler production has gained increasing importance because of its short production cycle, rapid turnover rate, and growing demand for poultry meat among consumers. Broiler production contributes substantially to national food supply and serves as a major source of livelihood for farmers across Nigeria.

The poultry industry is one of the fastest-growing segments of the livestock sector globally. In Nigeria, broiler production has expanded considerably due to population growth, urbanization, changing dietary preferences, and increasing awareness of the nutritional importance of animal protein. Poultry meat is widely consumed because it is relatively affordable, culturally acceptable, and free from many religious restrictions associated with other livestock products. Consequently, broiler production has become an attractive agricultural enterprise for both small-scale and commercial farmers.

Despite its economic importance, broiler production is highly sensitive to environmental conditions. Poultry birds require optimal temperature, humidity, ventilation, and water availability for efficient growth and productivity. Any deviation from these environmental requirements can adversely affect feed intake, growth performance, feed conversion efficiency, health status, and profitability. As a result, climate variability and climate change have emerged as major concerns for sustainable broiler production globally and particularly in tropical countries such as Nigeria.

Climate change refers to long-term alterations in weather patterns characterized by rising temperatures, changing rainfall patterns, increased frequency of extreme weather events, prolonged droughts, floods, and other environmental disturbances. Scientific evidence indicates that climate change is one of the greatest challenges facing agricultural production in the twenty-first century. The agricultural sector is particularly vulnerable because farming activities depend heavily on climatic conditions. Changes in temperature and rainfall patterns directly affect crop and livestock production systems, thereby threatening food security and rural livelihoods.

In Nigeria, the effects of climate change have become increasingly evident through rising temperatures, irregular rainfall distribution, increased incidence of droughts, flooding, and prolonged heat waves. These climatic events have significant implications for livestock production, particularly poultry enterprises. High environmental temperatures expose broiler birds to heat stress, which reduces feed consumption, slows growth rates, suppresses immunity, increases susceptibility to diseases, and elevates mortality rates. Such adverse effects ultimately reduce productivity and profitability among poultry producers.

Heat stress has been identified as one of the most severe consequences of climate change affecting broiler production in tropical environments. Broiler chickens are highly sensitive to heat because they possess limited mechanisms for dissipating excess body heat. When exposed to elevated temperatures, birds experience physiological stress, reduced appetite, impaired metabolism, poor feed conversion, and lower weight gain. In severe situations, excessive heat can lead to mass mortality and substantial economic losses for poultry farmers.

Climate change also affects broiler production indirectly through its impact on feed availability and feed costs. Poultry feed ingredients such as maize and soybean are highly dependent on climatic conditions for their production. Changes in rainfall patterns, droughts, and flooding often reduce crop yields, leading to shortages and increased prices of feed ingredients. Since feed accounts for the largest proportion of broiler production costs, increases in feed prices significantly affect farm profitability and sustainability.

Another major concern is the increased prevalence of diseases associated with changing climatic conditions. Variations in temperature and humidity create favorable environments for the proliferation of pathogens, parasites, and disease vectors. Climate-induced disease outbreaks increase veterinary costs, reduce flock performance, and contribute to higher mortality rates among broiler birds. Consequently, farmers face additional production risks and financial burdens resulting from climate variability.

The growing impacts of climate change have compelled poultry farmers to adopt various adaptation strategies aimed at reducing vulnerability and sustaining production. Climate change adaptation refers to adjustments in management practices, technologies, and production systems designed to minimize the adverse effects of changing climatic conditions. Adaptation enables farmers to enhance resilience, maintain productivity, and improve profitability despite environmental challenges.

Common climate change adaptation strategies among poultry farmers include the use of improved housing systems, installation of ventilation and cooling facilities, provision of adequate drinking water, adjustment of feeding schedules, adoption of heat-tolerant breeds, modification of stocking densities, tree planting around poultry houses, and improved disease control measures. These strategies help reduce heat stress and improve the overall welfare and productivity of broiler birds.

Studies have shown that adaptation strategies can significantly improve poultry farm performance when properly implemented. Farmers who invest in modern adaptation technologies often record lower mortality rates, higher growth performance, improved feed conversion efficiency, and greater profitability than those who fail to adapt. However, the adoption of adaptation measures varies considerably among farmers due to differences in education, access to information, farm size, financial resources, and institutional support.

Economic analysis of climate change adaptation strategies is important because adaptation often involves additional costs and investments. Farmers must allocate resources to housing modification, cooling technologies, improved management practices, and disease control measures. Understanding whether these investments generate positive returns in terms of productivity and profitability is essential for guiding policy decisions and encouraging wider adoption of effective adaptation practices.

Southwestern Nigeria represents one of the major poultry-producing zones in the country. States such as Lagos, Ogun, Oyo, Osun, Ondo, and Ekiti host a large concentration of commercial and semi-commercial poultry enterprises. The region contributes substantially to poultry meat supply in Nigeria and plays a vital role in employment generation and income creation. However, the region has experienced increasing climatic variability, including high temperatures, erratic rainfall patterns, and occasional flooding events, which pose significant challenges to poultry production.

Despite the growing concern over climate change and its implications for poultry production, there remains limited empirical evidence regarding the economic effects of adaptation strategies on broiler productivity and profitability in Southwestern Nigeria. Most existing studies have focused on climate change perceptions, adaptation practices, or technical efficiency without adequately examining the economic returns associated with adaptation investments. This study therefore seeks to fill this gap by conducting an economic analysis of climate change adaptation strategies and their effects on the productivity and profitability of broiler production enterprises in Southwestern Nigeria.

1.2 Statement of the Problem

Climate change has become one of the most significant threats to agricultural production worldwide. In Nigeria, rising temperatures, irregular rainfall patterns, prolonged heat waves, flooding, and other climate-related events have increasingly affected the performance of agricultural enterprises. The poultry industry, particularly broiler production, is highly vulnerable to these climatic changes because birds require specific environmental conditions for optimal growth and productivity. Deviations from these conditions often result in reduced feed intake, poor growth performance, disease outbreaks, and increased mortality rates.

Broiler producers in Southwestern Nigeria are increasingly confronted with climate-related challenges that threaten the sustainability of their enterprises. High temperatures and heat stress have become common occurrences, leading to reduced productivity and increased production costs. Additionally, climate change contributes to fluctuations in feed availability and prices, thereby increasing the financial burden on poultry farmers. These challenges negatively affect farm profitability and reduce the capacity of producers to expand their operations.

To minimize these adverse effects, many broiler producers have adopted various climate change adaptation strategies such as improved housing systems, enhanced ventilation, cooling technologies, tree planting, increased water provision, and improved disease management practices. While these strategies are intended to improve resilience and reduce vulnerability, they often require substantial financial investments. Consequently, questions remain regarding their effectiveness and economic viability among broiler producers.

Although several studies have examined climate change adaptation in agriculture, limited attention has been given to the economic implications of adaptation strategies in broiler production enterprises, particularly within Southwestern Nigeria. Existing studies have largely focused on adaptation practices and technical efficiency, with little emphasis on how adaptation influences productivity and profitability outcomes. This gap in knowledge limits the ability of policymakers, extension agents, and poultry farmers to make informed decisions regarding climate adaptation investments.

Therefore, this study seeks to analyze the climate change adaptation strategies adopted by broiler producers in Southwestern Nigeria and determine their effects on productivity and profitability. The findings will provide empirical evidence for designing policies and interventions aimed at enhancing climate resilience and sustainable broiler production.
