1.1 Introduction
Biochemistry is the branch of science that deals with the chemical processes and substances that occur within living organisms, including plants, animals, and microorganisms (Nelson & Cox, 2017). It focuses on understanding the molecular mechanisms that drive biological functions, such as metabolism, enzyme activity, genetic expression, and nutrient utilization. In the context of agriculture and food production, biochemistry plays a pivotal role in optimizing crop growth, improving soil fertility, enhancing nutritional quality, and managing plant and animal health.
Food security, defined as the consistent availability, access, and utilization of sufficient and nutritious food to meet the dietary needs of individuals and communities, remains a critical challenge in Nigeria (FAO, 2020). This chapter will address the background information that motivated this study, the challenges that prompted it, its aim, and its objectives as a preface to subsequent sections of the study. Additional factors include the study's significance, scope, limitations, research questions and hypotheses, and the definition of technical terms.
1.2 Background of Study
Biochemistry is a vital scientific discipline that examines the chemical processes within and related to living organisms. According to Nelson and Cox (2017), biochemistry provides insights into the molecular mechanisms that govern metabolism, enzyme activities, and genetic expression, all of which have direct implications for agriculture and food production. In the Nigerian context, biochemistry is instrumental in improving crop yields, enhancing nutritional quality, and ensuring sustainable food production systems. The integration of biochemical techniques into agriculture allows for innovations such as biofortification, enzyme-based pest management, and nutrient optimization in crops (Oluwole et al., 2021).
Food security remains a pressing challenge in Nigeria, with millions of people facing inadequate access to safe and nutritious food. The Food and Agriculture Organization (FAO, 2020) reported that despite Nigeria's vast arable land and agricultural potential, low productivity, climate variability, and post-harvest losses continue to impede food availability. Adeyemi and Chukwu (2020) asserted that the application of biochemical knowledge in agriculture is essential to mitigate these challenges, as it enhances both the quantity and quality of food produced. By improving the understanding of plant physiology, nutrient uptake, and soil fertility, biochemistry provides strategies for increasing crop resilience against environmental stresses and pest infestations.
According to Eze, Okafor, and Nwosu (2019), nutritional deficiencies in Nigeria, including protein-energy malnutrition and micronutrient insufficiencies, are exacerbated by poor agricultural practices and limited use of biofortified crops. They contended that biochemistry is central to addressing these deficiencies, as it informs the development of crops enriched with essential vitamins and minerals. The deliberate application of biochemical interventions in crop production ensures that the food grown is not only abundant but also nutritionally adequate to meet the dietary needs of the population.
Adeyemi and Chukwu (2020) stated that insufficient funding, inadequate infrastructure, and lack of trained personnel hinder the effective use of biochemical techniques at the farm level. Similarly, Oluwole et al. (2021) affirmed that while research has developed advanced methods for enhancing crop nutrition and pest resistance, these innovations are often underutilized due to weak linkages between research institutions and farmers. Furthermore, the application of biochemistry in animal husbandry is equally important. According to Akinola and Yusuf (2018), biochemical studies on feed composition, digestion, and metabolism have been critical in improving livestock productivity. They asserted that by optimizing feed quality and nutrient absorption, biochemical approaches increase meat, milk, and egg production, which in turn enhances food availability and contributes to economic stability.
Eze et al. (2019) contended that biochemical innovations are also essential in post-harvest management. Enzyme-based preservation techniques, microbial interventions, and bio-based packaging materials have been reported to significantly reduce post-harvest losses in fruits, vegetables, and grains. They affirmed that without these biochemical interventions, a substantial proportion of harvested food is wasted, further straining the already fragile food supply chain in Nigeria. The strategic application of biochemistry thus ensures that both the quantity and quality of food from farm to table are maintained, improving overall food security outcomes.
According to Oluwole et al. (2021), genetically modified crops with enhanced nutrient profiles and resistance to pests and diseases are vital in addressing both food scarcity and malnutrition. They reported that such crops reduce the reliance on chemical fertilizers and pesticides, promoting environmentally sustainable agricultural practices. On the other hand, the adoption of genetically improved crops in Nigeria is limited by regulatory challenges, public skepticism, and inadequate dissemination of information, which restricts the potential benefits of these biochemical innovations. This study is set against the backdrop of these challenges and opportunities, aiming to investigate the role of biochemistry in enhancing food security in Nigeria, with a focus on practical applications, nutritional improvements, and sustainable agricultural practices.
1.3 Statement of Problems
Investigation revealed that food insecurity remains a persistent challenge in Nigeria, affecting millions of individuals and households across the country. Biochemistry is crucial in enhancing food security as it is directly involved in improving crop yields, increasing resistance to pests and diseases, and developing biofortified foods rich in essential nutrients (Oluwole et al., 2021). The application of biochemical techniques in agriculture, such as soil nutrient analysis, enzyme-based pest control, and genetic modification of crops, is essential in addressing both qualitative and quantitative food deficits in Nigeria. On the other hand, limited awareness, inadequate funding, and poor integration of biochemical research into practical agricultural practices hinder the full potential of biochemistry in improving food production (Adeyemi & Chukwu, 2020).
Furthermore, many farmers still rely on traditional methods that are less efficient and more vulnerable to climate variations and soil depletion. In addition, nutritional deficiencies such as protein-energy malnutrition and micronutrient insufficiencies persist due to insufficient biofortification and lack of biochemical monitoring in food production (Eze et al., 2019). It is against this backdrop that this study seeks to investigate the role of biochemistry in enhancing food security in Nigeria.
1.4 Aim and Objectives of Study
