In Africa, nearly three-quarters of the population’s livelihoods depend directly on agriculture. While this remains to be the case, the agricultural productivity within the continent remains extremely low. Difficulties in adopting newer farming techniques contributes to this in comparison to easily releasable land potential.
Agriculture Main Income Sustainment
Agriculture makes up about 18 percent of the economy in Sub Sahara Africa which is significantly higher than the global average of 5 percent. Sixty percent of the population in Africa is skilled. Even in times of recession, particularly in rural locations, agriculture is intertwined with real life sustenance and serves as an economic pillar.
In Africa this ailment is easy to diagnose, stagnant farming technology combined with low weather dependability, shallow rainfall, little machinery, neglected farm investing, little overall investment reliant on weather. Even with the population continuing to boom and the available land, food is still imported which puts a strain on self sufficiency and economic growth.
Rain Dependant Regions: Irrigation and Farming
In comparison to advanced agricultural systems, Africa is still very far behind with regards to irrigation and farming. Only four percent of Africa’s cultivated land in the Sub Sahara is irrigated. This serves as a great limitation to farming in Africa. Spending too greatly on agriculture puts severe strain on the overall economy.
Heavy reliance on this form of agriculture brings very high risks.
Low Yields, High Stakes
Africa’s cereal yields average 1.7 tonnes per hectare, compared to a global average of roughly 4.2 t/ha. That means output per hectare in Africa is less than half the global norm.
Some countries have seen incremental improvements. For instance, cereal yield in Uganda is around 2.29 t/ha compared to the 3.87 t/ha global average. Other regions show slight gain—from 1.1 t/ha to 1.4 t/ha between 1990 and 2015—but the pace of increase remains slow. Low yields keep food self-sufficiency elusive and limit opportunities for agribusiness in Africa to scale.
Importing What Can Be Grown Locally
Africa’s low productivity translates into high import dependence. Continentwide, food imports are estimated at US$50 billion annually, with projections suggesting this could grow to US$90–110 billion by 2025 if productivity doesn’t improve.
Rice is a good example: Africa imports around 40% of the rice it consumes, making countries vulnerable to international price shocks—like the 2023 export restrictions from India.
In Tanzania, wheat imports cost US$385 million by early 2024, making up roughly 90% of domestic consumption. In Nigeria, agriculture contributes ~18% of GDP, but the country still spent US$4.7 billion on food imports in 2024. These figures highlight the scale of domestic production shortfalls and their economic implications.
A Glimpse of What Works: Innovation in Action
Despite the challenges, there are encouraging success stories.
In Côte d’Ivoire, the Smart Valleys initiative—simple, community-scaled irrigation systems—has more than doubled rice yields from 2 tonnes to 4.5 tonnes per hectare. This transformation came without heavy machinery or high-tech tools, proving that smart, localized interventions can meaningfully boost productivity.
These examples offer tangible evidence that agriculture innovation in Africa can deliver results when paired with appropriate technology and training.
Country Snapshots: Nigeria & Tanzania
Nigeria’s agricultural sector illustrates both potential and urgency. While farming accounts for nearly a fifth of GDP, low yields and food import dependence persist. The government has started to address this with AfDB-backed agro-processing zones designed to support domestic value chains—yet progress remains gradual.
Tanzania, meanwhile, heavily depends on agriculture: about 28.7% of GDP, 85% of exports, and half of all employment come from farming. Yet much of that production is subsistence-based, vulnerable to weather variation and shortcomings in input and infrastructure support.
These dynamics point to a pattern across many countries: agriculture is critical to livelihoods and economic output, yet productivity limitations continue to weaken its full potential.
A Formula for Transformation
To close this productivity gap, we must tackle known constraints with proven strategies:
- Expand irrigation and water control systems—from solar-powered pumps to community-managed irrigation—that reduce vulnerability to rainfall variability.
- Improve access to high-yield seeds, fertilizers, and training, encouraging adoption of integrated soil health practices.
- Invest in rural infrastructure and market access, helping reduce post-harvest losses and strengthen supply chains.
- Support local agribusiness growth and agro-processing, creating demand for locally grown crops and keeping value within domestic economies.
- Measure impact accurately, not just land under cultivation, but yield increases, losses prevented, and income gains.
The Bottom Line
Agriculture remains the single largest employer and a major driver of Africa’s GDP. Yet, it lags behind on productivity due to low irrigation, limited inputs, and weak value chains. That said, initiatives like Smart Valleys demonstrate that sustainable farming in Africa can bridge the gap between what is and what could be.
Greater investment in agribusiness in Africa and continued adoption of scalable innovations can elevate productivity, reduce food imports, and empower livelihoods. With the right focus, agriculture can fulfill its promise as a cornerstone of economic growth.
