As an agriculture-driven economy, Zambia relies heavily on affordable fertiliser to sustain production. But despite progress in developing a local fertiliser market particularly in blending the country remains highly exposed to global price shocks.
Escalating tensions between the United States and Iran are now threatening to push fertiliser costs even higher, raising concerns over input affordability and national food security, despite Zambia having no direct trade links with the Middle East.
Agricultural expert Samson Phiri says the impact is already being felt through global energy markets, where supply disruptions in key oil- and gas-producing regions are driving up fuel prices.
“The conflict has created uncertainty in global energy markets, disrupting supply chains and shipping routes. This has pushed up crude oil prices, and in turn, the cost of diesel, petrol, and natural gas,” Phiri said in an interview.
Higher energy prices are directly feeding into fertiliser production costs. Nitrogen-based fertilisers such as urea and ammonia are highly energy-intensive, with natural gas accounting for a significant share of production inputs. “When energy prices rise, fertiliser becomes more expensive to produce, and that cost is passed along the entire value chain,” he explained.
The impact is compounded by rising transport and logistics costs an even greater burden for landlocked Zambia.
“Fertiliser is a bulk commodity reliant on international shipping and inland distribution. Higher fuel prices increase costs at every stage, from importation to delivery to rural farmers,” Phiri noted.
Annually, Zambia imports between 800,000 and 1,000,000 metric tonnes of fertiliser, valued at between US$400 million and US$700 million, depending on global prices. Local production stands at an estimated 250,000 to 350,000 metric tonnes per year, largely made up of blended fertilisers.
However, key inputs such as urea remain predominantly imported, reinforcing the country’s exposure to international market fluctuations. Although Zambia sources much of its fertiliser from countries like Russia, China, Morocco, and South Africa, it remains fully exposed to global market dynamics. “Fertiliser markets are interconnected. Zambia doesn’t just import fertilizer it imports global price volatility,” Phiri said.
Global supply pressures are also intensifying. As of March 2026, China has restricted fertiliser exports, particularly nitrogen-potassium blends and certain phosphates, to protect domestic supply. At the same time, disruptions linked to U.S.-Iran tensions especially around the Strait of Hormuz are constraining global supply chains.
The Middle East remains a key supplier of ammonia and urea, meaning any conflict, sanctions, or logistical bottlenecks in the region quickly ripple across global markets.
“When supply tightens, buyers compete for alternative sources. That drives demand pressure and pushes prices higher worldwide,” Phiri explained.
Shipping disruptions, including along Red Sea routes, have further increased freight costs and insurance premiums, inflating the final landed price of fertiliser in Zambia. “For a landlocked country, these shocks are amplified. Goods travel longer distances through regional corridors, adding multiple layers of cost,” he added.
The implications for agriculture are significant. Rising fertiliser prices could force farmers to cut back on usage, reducing yields, increasing production costs, and limiting expansion.
“This goes beyond input costs it affects productivity, profitability, and ultimately food security,” Phiri warned.
Despite progress in local blending, Zambia still imports about 75% of its fertiliser, limiting its ability to cushion against global shocks especially for critical inputs like nitrogen.
Phiri who is also a 2025 Harvard APL fellow, called for strategic interventions, including increased investment in local manufacturing and the adoption of efficiency-enhancing solutions such as mono-fertilisers. “Zambia’s vulnerability is not about direct trade links it’s about being part of a global, price-sensitive system where shocks spread quickly,” he said.
As geopolitical tensions persist, fertiliser costs are emerging as a key pressure point for Zambia’s agricultural sector and a growing risk to the country’s food security outlook.
