Project – Climate Change Adaptation and Food Security in Benue State

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Climate change has emerged as one of the most significant environmental and developmental challenges confronting humanity in the twenty-first century. The phenomenon is characterized by long-term changes in temperature, precipitation patterns, humidity, wind circulation, and the frequency and intensity of extreme weather events resulting largely from anthropogenic greenhouse gas emissions (Intergovernmental Panel on Climate Change [IPCC], 2023). Climate change poses severe threats to economic growth, environmental sustainability, human health, and food production systems, particularly in developing countries where livelihoods depend heavily on climate-sensitive sectors such as agriculture.

Globally, agriculture remains one of the sectors most vulnerable to climate variability and change. Changes in rainfall patterns, rising temperatures, prolonged droughts, flooding, desertification, and increased pest and disease outbreaks have negatively affected agricultural productivity across different regions of the world. The Food and Agriculture Organization (FAO, 2023) reports that climate-related shocks continue to undermine food systems, reduce crop yields, threaten livestock production, and increase the vulnerability of rural households. Consequently, climate change has become a major threat to global food security and sustainable development.

Food security exists when all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life (FAO, IFAD, UNICEF, WFP, & WHO, 2024). The concept encompasses four major dimensions: food availability, food accessibility, food utilization, and food stability. Any disruption in these dimensions can lead to food insecurity, malnutrition, hunger, and poverty. Climate change directly affects all four dimensions by reducing agricultural productivity, increasing food prices, disrupting food supply chains, and limiting access to adequate nutrition.

Over the years, scientific evidence has demonstrated that climate change poses substantial risks to agricultural production. Increased temperatures can reduce crop yields by accelerating evapotranspiration and reducing soil moisture. Similarly, irregular rainfall patterns can affect planting seasons, crop growth cycles, and harvest periods. Extreme weather events such as floods and droughts often destroy farmlands, crops, livestock, and agricultural infrastructure, thereby reducing food availability and increasing food insecurity (Porter et al., 2014).

Sub-Saharan Africa is among the regions most vulnerable to climate change due to its dependence on rain-fed agriculture, widespread poverty, limited adaptive capacity, and weak agricultural infrastructure. The region’s agricultural systems are highly sensitive to climatic fluctuations, making millions of rural households vulnerable to food insecurity. According to the IPCC (2022), climate change is expected to significantly reduce agricultural productivity in many African countries if effective adaptation measures are not implemented.

Nigeria, as Africa’s most populous country, faces significant challenges arising from climate change. Agriculture contributes substantially to employment, food production, and rural livelihoods, with a large proportion of the population depending directly or indirectly on farming activities. However, changing climatic conditions have increasingly affected agricultural production across the country. Incidents of flooding, drought, irregular rainfall, heat stress, soil degradation, and pest infestations have become more frequent, negatively impacting food production and rural livelihoods (Federal Ministry of Environment, 2021).

The Nigerian agricultural sector is particularly vulnerable because the majority of farmers operate on a small scale and depend primarily on rainfall for crop production. Variations in climatic conditions therefore have direct consequences for agricultural productivity and food security. Studies have shown that climate change has contributed to declining crop yields, reduced farm income, increased food prices, and worsening food insecurity in several parts of Nigeria (Nwajiuba et al., 2021).

Among Nigeria’s states, Benue State occupies a strategic position in national food production. Popularly referred to as the “Food Basket of the Nation,” Benue State is endowed with fertile agricultural land, favorable climatic conditions, extensive river systems, and a large farming population. The state is a major producer of yam, cassava, rice, maize, millet, sorghum, soybean, groundnut, vegetables, and fruits. Agriculture remains the dominant economic activity and the primary source of livelihood for a significant proportion of the state’s population.

The importance of Benue State in Nigeria’s food system makes climate change impacts particularly significant. In recent years, farmers in the state have experienced increasing climatic variability characterized by delayed rainfall, shorter growing seasons, excessive rainfall, flooding, prolonged dry spells, and rising temperatures. These changes have adversely affected agricultural production, leading to crop losses, reduced yields, destruction of farmlands, and declining farm incomes.

Flooding has emerged as one of the most devastating climate-related challenges in Benue State. Due to its location along the River Benue and other tributaries, the state is highly susceptible to seasonal flooding. Major flood events recorded in recent years have destroyed thousands of hectares of farmland, displaced farming households, disrupted agricultural activities, and threatened food production. Reports from the National Emergency Management Agency (NEMA) indicate that recurrent floods continue to pose serious threats to agricultural productivity and food security in the state.

Climate change has also contributed to increasing uncertainty in agricultural planning and decision-making. Farmers often find it difficult to predict planting and harvesting periods due to irregular rainfall patterns. Such uncertainties increase production risks and reduce agricultural efficiency. Consequently, many farming households experience reduced productivity, declining incomes, and heightened vulnerability to food insecurity.

In response to these challenges, climate change adaptation has become an essential strategy for enhancing agricultural resilience and ensuring food security. Climate change adaptation refers to adjustments in ecological, social, and economic systems in response to actual or expected climatic stimuli and their effects. Adaptation measures seek to reduce vulnerability, minimize risks, and enhance the capacity of individuals and communities to cope with climate-related challenges (IPCC, 2022).

Agricultural adaptation strategies include the adoption of improved crop varieties, drought-resistant seeds, irrigation systems, agroforestry practices, crop diversification, conservation agriculture, climate-smart agriculture, improved water management techniques, weather information utilization, and sustainable land management practices. These strategies help farmers cope with climate variability and maintain agricultural productivity despite changing environmental conditions (Lipper et al., 2014).

Climate-smart agriculture has emerged as a particularly important adaptation approach because it simultaneously enhances productivity, strengthens resilience, and reduces greenhouse gas emissions. The FAO (2023) emphasizes that climate-smart agricultural practices can significantly improve food security outcomes while enabling farming communities to adapt to changing climatic conditions.

Despite growing awareness of climate change adaptation, the adoption of adaptation strategies among farmers in Benue State remains uneven. Factors such as limited access to finance, inadequate extension services, poor infrastructure, insufficient climate information, low educational attainment, land tenure constraints, and weak institutional support continue to limit adaptation efforts. Consequently, many farmers remain highly vulnerable to climate-induced agricultural risks.

Furthermore, while government agencies, development organizations, and research institutions have introduced various adaptation programmes and interventions, concerns persist regarding their effectiveness in enhancing food security among farming households. The extent to which adaptation strategies contribute to improved agricultural productivity, food availability, and household food security remains an important area of investigation.

Given the strategic importance of Benue State in Nigeria’s food production system and the increasing threats posed by climate change, there is a need to examine the relationship between climate change adaptation and food security. Understanding how adaptation measures influence food security outcomes is critical for designing effective policies and interventions aimed at enhancing agricultural resilience and sustainable food production.

It is against this backdrop that this study seeks to investigate climate change adaptation and food security in Benue State. The study examines adaptation strategies adopted by farmers and evaluates their contributions to food security within the state.

1.2 Statement of the Problem

Climate change has become a major threat to agricultural productivity and food security globally. Developing countries, particularly those dependent on rain-fed agriculture, are increasingly experiencing the adverse effects of changing climatic conditions. Rising temperatures, irregular rainfall patterns, prolonged droughts, flooding, and extreme weather events continue to undermine agricultural production and rural livelihoods.

In Nigeria, climate change poses serious challenges to the agricultural sector, which remains a critical source of employment, income, and food supply. Agricultural productivity has increasingly been affected by climate variability, resulting in declining crop yields, reduced farm incomes, and heightened food insecurity among farming households.

Benue State, widely recognized as the “Food Basket of the Nation,” has not been exempt from these challenges. Despite its enormous agricultural potential, the state has experienced recurrent climate-related disasters, particularly flooding, erratic rainfall, and rising temperatures. These climatic changes have disrupted farming activities, destroyed crops, reduced agricultural output, and threatened the livelihoods of farming communities.

The recurring floods witnessed in many parts of Benue State have resulted in substantial losses of farmland, agricultural investments, and food production. In addition, irregular rainfall patterns and prolonged dry spells have affected planting schedules and crop growth cycles, thereby increasing production uncertainties and reducing agricultural productivity. Consequently, food insecurity has become a growing concern among rural households in the state.

Although climate change adaptation strategies have been promoted by government agencies, development partners, and agricultural institutions, evidence suggests that the adoption of these strategies remains inadequate among many farmers. Factors such as poor access to credit, limited extension services, inadequate awareness, weak institutional support, and infrastructural deficiencies continue to constrain adaptation efforts.

Furthermore, there is limited empirical evidence regarding the effectiveness of climate change adaptation strategies in improving food security outcomes in Benue State. While several studies have examined climate change impacts on agriculture in Nigeria, fewer studies have specifically investigated how adaptation measures influence food availability, accessibility, utilization, and stability within farming households in Benue State.

The problem therefore is that despite the increasing adoption of climate change adaptation measures and various intervention programmes, food insecurity remains prevalent among many farming households in Benue State. This raises concerns regarding the effectiveness of existing adaptation strategies in enhancing agricultural resilience and ensuring food security. Consequently, this study seeks to examine the relationship between climate change adaptation and food security in Benue State.
