1.1 Introduction
Operational Research (OR) is a discipline that applies advanced analytical methods to help make better decisions and solve complex problems in various fields, including agriculture. According to Ghosh et al. (2018), Operational Research involves the use of mathematical models, statistical analyses, and optimization techniques to improve efficiency, resource utilization, and decision-making in systems where multiple factors interact. In agriculture, Operational Research is utilized to optimize resource allocation, plan crop production, manage labor and machinery, and enhance overall farm productivity (Ghosh et al., 2018).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitation of the study and Definition of terms.
1.2 Background of the Study
Over the years, scholars have contended that the integration of Operational Research with modern technologies supports precision agriculture, improves yield optimization, and promotes sustainable resource management. According to IJARIIT (2019), farms that implement OR techniques alongside technological tools report increased efficiency, reduced input wastage, and more effective crop planning. The historical development of OR demonstrates its evolution from military strategy to a critical tool for optimizing agricultural productivity, particularly in countries like Nigeria where resource efficiency and sustainable farming are of high importance.
Operational Research (OR) originated during the Second World War when military planners sought systematic and scientific methods to solve complex operational problems. According to Coyle (2004), OR was initially developed to improve logistics, strategy, and resource allocation in military operations. Its success in optimizing critical decision-making processes led to its adoption in civilian sectors, including manufacturing, transportation, healthcare, and agriculture.
The application of OR in agriculture began in the mid-20th century as researchers sought to address inefficiencies in farm management and crop production. Ghosh et al. (2018) reported that early applications of OR in agriculture involved linear programming, simulation models, and queuing theory to optimize resource allocation, labor management, and crop planning.
In Nigeria, the use of OR in agriculture has gradually expanded, although its adoption remains limited. Babar and Akan (2024) asserted that Nigerian agricultural systems face challenges such as insufficient technical expertise, limited access to reliable data, and underdeveloped computational infrastructure, which have slowed the widespread implementation of OR techniques. On the other hand, modern advances in technology, including Geographic Information Systems (GIS), Artificial Intelligence (AI), and the Internet of Things (IoT), have enhanced the potential for OR to transform agricultural practices by enabling predictive modeling, real-time monitoring, and improved decision-making (Carravilla & Oliveira, 2013).
Operational Research (OR) is a scientific approach to decision-making and problem-solving that involves the application of mathematical, statistical, and analytical techniques to optimize outcomes in complex systems. According to Ghosh et al. (2018), Operational Research provides a structured framework for managing resources efficiently, improving operational performance, and making informed decisions in diverse sectors including agriculture. It is widely recognized as a critical tool for enhancing productivity, planning, and resource management in farming systems.
In Nigeria, agriculture remains the backbone of the economy, contributing significantly to employment, food production, and national GDP. However, agricultural productivity is often hindered by inefficient resource allocation, poor planning, unpredictable weather patterns, pest and disease infestations, and lack of access to modern technologies. Babar and Akan (2024) reported that the adoption of OR techniques is still limited in Nigerian agriculture, and many farmers rely on traditional methods that do not maximize output or efficiency.
Carravilla and Oliveira (2013) asserted that integrating OR into agricultural practices improves crop planning, labor management, and input utilization, thereby enhancing overall productivity. Similarly, Ghosh et al. (2018) stated that OR techniques such as linear programming, simulation, and optimization models enable farmers to make data-driven decisions that reduce waste and increase profitability. On the other hand, the challenges of inadequate technical knowledge, insufficient computational tools, and limited access to accurate agricultural data restrict the practical application of OR in many farming communities.
According to IJARIIT (2019), scholars contend that modern technologies such as Geographic Information Systems (GIS), Artificial Intelligence (AI), and the Internet of Things (IoT) complement OR by providing real-time data, predictive analysis, and enhanced decision-making capabilities (IJARIIT, 2019). Affirmed by The Guardian (2024), the integration of these technologies with OR methods has led to significant improvements in resource optimization, crop yield prediction, and sustainable farm management in various regions. This study is set against the backdrop of understanding the role of Operational Research in improving agricultural productivity in Nigeria.
1.3 Statement of Problems
Agriculture remains the backbone of Nigeria’s economy, providing employment, food security, and raw materials for various industries. However, agricultural productivity is often limited by inefficient resource utilization, poor planning, and suboptimal decision-making. Operational Research (OR) is an analytical tool that is designed to improve decision-making and optimize the use of resources in complex systems, including agriculture (Ghosh et al., 2018).
On the other hand, farmers and agricultural managers often face challenges such as insufficient access to reliable data, lack of technical expertise, inadequate computational tools, and resistance to adopting new technologies. Limited awareness and training on the benefits and practical application of Operational Research techniques further hinder its integration into day-to-day agricultural practices (Babar & Akan, 2024).
Additionally, the absence of coordinated policies and insufficient support from government and institutional frameworks restrict the scalability and sustainability of Operational Research applications in agriculture. The inefficiency in current planning methods and the underutilization of modern technologies such as AI, GIS, and IoT result in suboptimal resource allocation and reduced crop yields, affecting overall agricultural productivity and economic growth (Carravilla & Oliveira, 2013). It is against this backdrop that this study seeks to investigate the role of Operational Research in enhancing agricultural productivity optimization in Nigeria.
