Africa Is Rich in Farmland but Poor in Sustainability: It’s Time to Change That

- The Paradox of Plenty
Africa possesses almost half of the world’s remaining arable land, yet the continent continues to struggle with hunger and poverty. The irony is striking: a land so fertile and vast that it could feed the world still cannot fully feed its own people. From the plains of Sudan to the valleys of Ghana, and from the highlands of Kenya to the savannahs of Nigeria, millions of farmers cultivate the soil with hope, but their yields remain stubbornly low.
This is not due to laziness or lack of potential but a crisis born of exhaustion, neglect, and poor stewardship of natural resources. Over the decades, African agriculture has largely been driven by expansion rather than regeneration. When soils lose fertility, the instinct has been to move on to new land rather than restore the old. Forests are cleared, wetlands drained, and fragile ecosystems stripped of nutrients in a desperate effort to sustain livelihoods. This relentless pattern of expand and abandon has degraded more than 65 percent of agricultural land in sub-Saharan Africa.
The problem runs deeper than soil alone. Fertilizer use in Africa averages between 13 and 20 kilograms per hectare of arable land, far below the global average of about 135 kilograms per hectare. Less than 6 percent of the continent’s cropland is irrigated, leaving millions of farmers entirely dependent on erratic rainfall. As a result, cereal productivity remains less than half the global average. What should be an engine of growth has become a treadmill of toil.
The paradox of plenty is therefore not a question of how much land Africa has, but how poorly that land is managed. The continent’s future depends not on expansion into new lands but on transforming the productivity and sustainability of the soil it already possesses.
- The Shrinking Farm and the Rising Burden
The heartbeat of African agriculture lies in its smallholder farms. These family-run plots, often less than one hectare, supply up to 70 percent of the continent’s food. Yet they are increasingly squeezed by the twin forces of population growth and environmental decline. As families grow, land is subdivided generation after generation until the plots become too small to sustain a household.
In places such as Ethiopia, Malawi, and Uganda, the average smallholder farm is now so tiny that even doubling its yield would still leave many families below the poverty line. A farmer cultivating half a hectare of maize can only produce enough food to feed the household for a few months before hunger returns. The rest of the year is spent struggling to buy food at high market prices or seeking casual labor in nearby towns.
The pressures do not stop there. Climate change has made rainfall unpredictable and droughts more frequent. Pest infestations such as the fall armyworm have devastated staple crops. Depleted soils have lost their structure and their ability to retain water. The economic cost of this environmental decline is staggering, draining nearly seven percent of sub-Saharan Africa’s GDP each year. For farmers, that translates into lower incomes, higher risks, and fewer opportunities for the next generation.
Rural youth are increasingly turning away from agriculture, viewing it as a symbol of hardship rather than hope. Without new incentives and technologies to make farming profitable and sustainable, Africa risks losing its next generation of food producers. The small farm, once a cornerstone of resilience and community, is fast becoming a burden that few young people are willing to carry.
- Sustainable Farming Is the Future
Despite Africa’s agricultural challenges, a quiet revolution is unfolding across the continent. From the terraced hills of Rwanda to the dry plains of Niger, farmers are rediscovering the power of sustainable agriculture, an approach that values regeneration over exploitation and productivity over depletion.
chiprestoring fertility and improving crop yields while protecting against desertification. In Kenya, smallholders are using compost, crop rotation, and intercropping systems that combine legumes with cereals to naturally replenish nitrogen in the soil. In Ghana, farmers are experimenting with integrated pest management to reduce chemical use and protect pollinators. These practices demonstrate that sustainability is not an obstacle to productivity; it is its foundation.
Sustainable farming is about balance. It seeks to increase yields without destroying the ecosystem. It recognizes that soil is not an infinite resource but a living system that needs care. It encourages the use of organic matter, efficient water harvesting, and mixed cropping that mimics natural ecosystems. When combined with technology such as mobile based weather alerts, soil testing kits, and precision irrigation, sustainable farming becomes both profitable and resilient.
As the Alliance for a Green Revolution in Africa emphasizes, sustainable farming must be context specific and locally led. What works in the Ethiopian highlands may not suit the dry plains of Namibia or the coastal belts of West Africa. Yet the principles remain universal: build soil health, use water efficiently, protect biodiversity, and empower farmers with knowledge.
The benefits of such approaches are already visible across Africa. Regenerative farming techniques such as conservation tillage, composting, and improved water management have helped farmers achieve higher yields, restore degraded soils, and reduce dependence on costly external inputs. In many countries, these practices have improved soil moisture retention, increased organic matter, and enhanced the resilience of crops to drought and erratic rainfall. Farmers who adopt such methods often report greater stability in harvests and lower risks during climate extremes. Sustainable farming is not merely an environmental strategy but an economic lifeline.
- A Call for Visionary Leadership
Transforming Africa’s farmland into a foundation for prosperity requires leadership that matches the scale of the challenge. Governments, private investors, and development partners must recognize that sustainability is not an environmental afterthought but a core driver of agricultural growth.
Governments should begin by securing land rights for smallholder farmers, particularly women, who make up nearly half of the agricultural workforce but own only a fraction of the land they cultivate. Investment in rural infrastructure such as irrigation networks, storage facilities, and feeder roads is essential to connect farmers with markets and reduce postharvest losses. Equally important is revitalizing agricultural extension systems so that innovations and research findings reach the farmers who need them most.
The private sector also has a pivotal role to play. Instead of extractive agribusiness models that deplete soil and water resources, companies should embrace regenerative value chains that reward farmers for adopting sustainable practices. Green financing, climate smart technologies, and fair market access can create new opportunities for rural communities while safeguarding the environment.
International partners and donors must shift from short term project funding to long term collaboration that strengthens local capacity. Development assistance should catalyze innovation, not dependency. Partnerships among universities, research institutions, and farmer cooperatives can accelerate the spread of climate resilient crops and locally appropriate farming systems.
The economic case is clear when one considers that restoring degraded land, improving soil health, and promoting sustainable agriculture can generate substantial returns through higher productivity, reduced disaster losses, and stronger rural economies. Every hectare restored represents both environmental recovery and economic renewal.
Africa’s agricultural future will not be defined by how much land it has but by how wisely that land is managed. The soil beneath our feet is both inheritance and insurance. Protecting it is not only an act of stewardship but a strategic investment in the continent’s prosperity.
