Climate-smart agriculture and the economics of food security in Nigeria’s dryland farming systems

Across Nigeria’s northern agricultural belt, a quiet but consequential shift is underway. Climate variability, once considered a long-term environmental concern, is now exerting immediate pressure on agricultural productivity, rural incomes, and the broader stability of food markets. In dryland regions where farming systems already operate within narrow ecological margins, the stakes are particularly high.

For millions of smallholder farmers, the growing unpredictability of rainfall patterns and the steady decline in soil fertility are not abstract scientific concepts, but lived economic realities. A delayed rainy season can mean missed planting cycles, while an early cessation of rains can wipe out months of labour. Over time, these disruptions compound into reduced yields, lower incomes, and increased vulnerability across entire communities.

At a national level, these micro-level shocks translate into supply fluctuations, price volatility, and mounting pressure on food systems. As Nigeria continues to grapple with food security challenges, it is becoming increasingly clear that traditional approaches to agriculture are no longer sufficient. What is required is a transition toward systems that are not only productive, but sustainable and resilient.

In this conversation,  Olurotimi Ogundijo, an Agricultural Economist and Sustainable Food Systems Specialist with extensive field experience in Northeast Nigeria, offers a grounded and forward-looking perspective on how climate-smart agriculture can reshape the economics of dryland farming. Drawing from years of hands-on program implementation and policy engagement, he outlines not only the technical pathways to resilience, but also the structural shifts required to secure Nigeria’s agricultural future.

 Climate change is often discussed in environmental terms. From your perspective, how should Nigeria understand it as an economic issue?

One of the most important shifts we need to make is to stop treating climate change as something external to the economy. In an agrarian system like Nigeria’s, climate variability is already embedded in economic outcomes. It influences productivity, income stability, and even national price dynamics.
When rainfall becomes unpredictable, it disrupts the entire planning cycle of farming. Farmers cannot rely on historical patterns, which introduces uncertainty into decision-making. That uncertainty reduces investment at the farm level and lowers productivity over time.

At a broader level, reduced output in key agricultural regions creates supply shocks. These shocks translate into higher food prices, increased inflationary pressure, and reduced purchasing power, particularly for low-income households. So what begins as a climatic disruption evolves into a macroeconomic issue.
In that sense, climate change should be understood as a structural economic risk. Addressing it is not only about environmental sustainability, but about protecting productivity, stabilising markets, and preserving livelihoods.

What distinguishes dryland farming systems in Northern Nigeria from other agricultural zones?

Dryland systems are defined by constraint. They operate within limited rainfall, fragile soils, and a narrow margin for error. Unlike more humid zones where farmers may have multiple cropping opportunities, dryland farmers often have a single production window.
This creates a high-risk environment. If rainfall is delayed or poorly distributed, the consequences are immediate and severe. There is very little opportunity to recover within the same season.
Additionally, soil degradation compounds the challenge. Years of continuous cultivation without adequate nutrient replenishment have reduced soil productivity. So even when rainfall conditions are favourable, output may still be suboptimal.
What this means is that interventions must be highly contextual. Generic agricultural solutions tend to fail in these systems. Any effective approach must address water management, soil health, and risk mitigation simultaneously.

 Climate-smart agriculture is gaining attention. What does it actually mean in practical terms for farmers?

At the farmer level, climate-smart agriculture is about making informed adjustments that improve both resilience and efficiency. It is not about introducing entirely new systems, but about refining existing practices in a more sustainable way.
For instance, adjusting planting dates based on evolving rainfall patterns can significantly improve outcomes. Incorporating organic matter into the soil enhances its structure and water retention capacity, which becomes critical during dry periods.

Diversification is another key element. When farmers cultivate a mix of crops, they spread risk. If one crop fails due to climatic conditions, others may still perform.
What is important is that these practices are integrated. When farmers apply them as part of a system, they begin to see cumulative benefits—more stable yields, reduced input costs, and improved resilience. That is when climate-smart agriculture transitions from theory to practical value.

 How does sustainability differ from climate-smart agriculture, or are they the same?
They are closely related, but not identical. Climate-smart agriculture focuses on adapting to and mitigating climate risks, while sustainability is broader. It considers the long-term viability of the entire farming system, including environmental, economic, and social dimensions.

In practice, climate-smart approaches are often pathways to sustainability. For example, improving soil health or conserving water addresses both climate resilience and long-term productivity.

However, sustainability goes further. It asks whether a farming system can continue to function effectively over time without degrading its resource base or becoming economically unviable. In the context of Nigeria, particularly in fragile regions, sustainability should be the ultimate goal, with climate-smart practices serving as key tools to achieve it.

How economically viable are these climate-smart and sustainable practices for smallholder farmers?

Economic viability is the determining factor for adoption. Farmers will not sustain practices that do not improve their livelihoods.
The advantage of many sustainable approaches is that they optimise local resources. Composting, for instance, reduces dependence on external fertilisers. Water conservation techniques improve efficiency without requiring large investments.Over time, these practices stabilise yields and reduce costs. That combination improves income resilience, which is particularly important in volatile environments.
However, adoption does require initial support. Training, demonstration, and community engagement are essential to help farmers understand both the short-term adjustments and long-term benefits.

Soil fertility is a recurring issue. Why is it so central to both sustainability and economic outcomes?
Soil fertility is the foundation of agricultural productivity. When soils are degraded, every other input becomes less effective, and the cost of production increases.
From an economic perspective, poor soil health traps farmers in a cycle of low output and low income. They produce less, earn less, and are unable to invest in improving their land. This cycle reinforces poverty over time.

Improving soil fertility, particularly through sustainable methods, breaks that cycle. When soil health improves, yields increase, and income follows. More importantly, the system becomes more stable and less dependent on continuous external inputs.
At a broader scale, healthier soils contribute to more consistent regional production, which supports market stability and food availability.

Irrigation is often seen as a solution. What role does it realistically play in dryland agriculture?
Irrigation is critical, but it must be approached in a way that aligns with local realities. Large-scale irrigation systems are important, but they are capital-intensive and take time to develop.
In the meantime, small-scale, accessible solutions can have immediate impact. Simple technologies such as water harvesting systems or low-cost irrigation tools enable farmers to extend their growing season.
This is particularly important for income diversification. Dry-season farming creates additional revenue streams and reduces reliance on a single harvest.
Sustainability here lies in accessibility. Solutions must be affordable, manageable, and adaptable to local conditions if they are to be widely adopted.

 How can farmers balance productivity with sustainability in these fragile ecosystems?
The key is to recognise that sustainability supports productivity over the long term. Practices that degrade the environment may increase output temporarily, but they undermine future production.
Sustainable approaches focus on maintaining the integrity of the system—soil, water, and biodiversity. When these are preserved, productivity becomes more stable and predictable.
What we encourage is a shift in mindset. Farmers begin to see their land not just as a resource to be used, but as a system to be managed. That perspective naturally leads to more sustainable decisions.

 What role does knowledge and extension play in scaling these practices?
Knowledge is perhaps the most critical factor. Many sustainable practices are not input-heavy, but they require understanding.
Extension systems are designed to provide this knowledge, but they are often under-resourced. As a result, alternative models become important.
Community-based learning, where farmers share experiences and observe results within their own environment, has proven effective. When knowledge is localised and practical, adoption increases significantly.

Are there examples where these approaches have delivered measurable results?
Yes, and those examples are essential for building confidence. In several interventions, combining soil management with improved agronomic practices led to noticeable increases in yield within a single season.
However, the more important outcome was stability. Even in less favourable conditions, farmers experienced less severe declines in output compared to traditional methods.
This consistency allows farmers to plan more effectively, invest with greater confidence, and engage more actively in markets.

 How does climate variability affect food prices and market stability?
Climate variability introduces uncertainty into supply, and markets respond accordingly. When production declines, supply tightens, and prices rise.
This creates challenges for consumers and risks for farmers. Higher prices are only beneficial if farmers have sufficient produce to sell.
By stabilising production through sustainable practices, we can reduce these fluctuations. More consistent supply leads to more stable markets, which benefits both producers and consumers.

 What role should government play in promoting sustainable agriculture?
Government plays a central role in creating an enabling environment. This includes investing in research, strengthening extension systems, and providing policy support for sustainable practices.
It is also important to integrate sustainability into mainstream agricultural policy. It should not be treated as a separate agenda, but as a core component of long-term strategy.

How can private sector investment support this transition?
The private sector can drive efficiency and scale. Investments in storage, processing, and logistics reduce losses and improve market access.
There is also opportunity in developing and distributing affordable technologies that support sustainable practices. When these innovations are accessible, adoption becomes easier.

What are the biggest barriers to scaling sustainable agriculture in Nigeria?
The barriers include limited knowledge, infrastructure constraints, and financial limitations. These factors are interconnected and must be addressed collectively.
No single intervention will be sufficient. A coordinated approach is required to create meaningful and lasting change.

 How does sustainability influence long-term national food security?
Sustainability is central to long-term food security. Without it, production systems degrade, and gains cannot be maintained.
A sustainable system ensures that food can be produced consistently over time, even under changing conditions. That consistency is what underpins food security at the national level.

What misconceptions exist about climate-smart agriculture in Nigeria?
One common misconception is that it is expensive or overly technical. In reality, many practices are simple and based on improving existing systems.
Another misconception is that it is optional. Given current climate trends, adopting sustainable practices is becoming a necessity rather than a choice.

 Looking ahead, what are the most critical priorities for dryland regions?
Improving soil health, expanding water access, and strengthening knowledge systems are key priorities. These elements form the foundation of sustainable production.

Finally, what is your outlook on the future of agriculture in Nigeria?
The outlook is cautiously optimistic. The challenges are significant, but there is growing awareness of the need for sustainable approaches.
If policy, investment, and knowledge systems are aligned, Nigeria has the potential to build a more resilient and productive agricultural sector. The key is consistency in action and commitment to long-term thinking.

Closing note
As climate pressures intensify, the future of Nigeria’s food systems will increasingly depend on how well sustainability is embedded into agricultural practice. What is emerging is not just a shift in technique, but a shift in thinking, one that recognises that resilience, productivity, and sustainability must work together to secure long-term economic and food system stability.
