IN THE HIGHLANDS of Ethiopia’s Oromia region, the boundary between a flower farm and a food farm is marked by a fence and, on one side of it, a silence. The greenhouse is sealed, climate-controlled, buzzing with fans and irrigation pumps. On the other side, a smallholder farmer tends a diminishing patch of teff and barley with a hand plough. The two operations could not appear more different. They are, however, connected — by the land one has taken from the other, and by the soil that neither can afford to waste.
The cut-flower industry’s relationship with fresh water has attracted scrutiny from environmentalists, development economists, and conscience-stricken European consumers for the better part of two decades. Less examined, but in many ways more consequential for the long-term productive capacity of developing economies, is what floriculture does to land. It occupies it, competes for it, degrades it, and sometimes renders it unfit for food production long after the greenhouses have moved on. In a world where an estimated 65% of arable land in Sub-Saharan Africa is already degraded, with annual soil nutrient losses worth approximately $4 billion, the addition of an industry that devours some of the best-positioned agricultural land for inedible luxury goods is not a marginal problem.
The Prize Acreage Problem
The first thing to understand about floriculture is where it goes. Flower farms do not seek marginal land. They seek the opposite: flat, fertile, well-watered highland terrain with access to roads, airports, and electricity. In Ethiopia, this means the land ringing Addis Ababa — the Sululta plateau, the Ziway basin, the areas around Holeta and Debre Zeit. In Kenya, it means the fertile volcanic soils of the Rift Valley. In Colombia, it means the Sabana de Bogotá, one of the most productive agricultural plateaux in the Andes. In Ecuador, it means the Pichincha highlands around Quito.
This is, without exception, land that could grow food. Not marginal scrubland or degraded hillside. The same elevation, climate stability, and soil quality that make these regions so attractive for flower production are the qualities that define prime arable land. A central reason for Africa’s continuing food insecurity is the channelling of good land toward cash crops for export, displacing food production onto marginal areas — a pattern established during the colonial era and continued into the present by commercial floriculture and other export industries. The flower industry did not invent this dynamic. It has, however, refined it to a remarkable degree of efficiency.
The scale of direct land conversion, while smaller than that of commodity crops such as soy or palm oil, is locally significant. In Ethiopia, approximately 145 hectares of land were documented as converted directly from food to flower production in a single catchment study, with further changes recorded in the Ziway and Abyata lake catchments. These figures almost certainly undercount the total, since land conversion often proceeds informally and monitoring is inconsistent. What is more reliably documented is the displacement effect: when prime land is enclosed by a commercial flower operation, the farmers who previously worked it do not stop farming. They move onto less suitable land nearby, increasing pressure on soils that were already fragile, clearing whatever vegetation remained, and beginning the cycle of degradation that follows when farmers have too little land for too many mouths.
From Landowner to Day Labourer
The most direct human consequence of floriculture’s land appetite is what researchers have come to call the “smallholder to wage labourer” transition. It sounds, on paper, like development — subsistence farmers joining the formal economy, earning wages rather than growing food that feeds only their own households. In practice, it is frequently the reverse of progress.
Research in Ethiopia’s Sululta District found that floriculture expansion has had detrimental consequences for smallholder farmers, including loss of access to agricultural land, disruption of grazing spaces, social and economic displacement, and erosion of cultural and social cohesion, threatening food security and traditional agricultural systems. The transition from landowner to wage labourer represents a fundamental shift in economic security: where a family once controlled a productive asset that could feed them in bad years, they now depend on an employer who can reduce shifts, impose seasonal contracts, or close entirely if export prices fall.
The study in Sululta highlights the socioeconomic non-sustainability of smallholder farmers due to social insecurity, agricultural product damage, arable land and water resource access restrictions, and a resulting shift to daily labour. The word “non-sustainability” is academic understatement. Families that once cultivated a diversity of food crops now eat what they can buy on wages that, according to researchers, left previous landowners raising complaints against investors while state employees became private sector workers with reduced protections.
The colonial parallel is not accidental. Historical literature documents how the colonial introduction of export cash crops — coffee, tea, cotton, tobacco — undermined food crop production by competing for seasonally scarce labour, and that attempts to direct African smallholders into growing such crops consistently compromised domestic food production. The floriculture industry, arriving in Ethiopia a century later with greenhouses rather than administrative coercion, has reproduced the same dynamic through market mechanisms instead. The outcome for the farmer looking at a fence where her barley field used to be is structurally identical.
Soil: What Flowers Leave Behind
The land question is not simply about who farms which plot. It is about what kind of farming takes place, and what condition the soil is in afterwards. Here the floriculture industry’s record is considerably worse than its proponents typically acknowledge.
Commercial flower production is among the most chemically intensive forms of agriculture on earth. Ecuador applies between six and eight fungicide treatments per crop cycle, alongside multiple insecticide and nematicide applications. Colombian farms historically used approximately 200 kilograms of pesticides per hectare annually — a figure that alarmed public health researchers for decades before regulatory pressure began to reduce it. In Ethiopia, researchers documented how chemicals released from flower farms negatively affect soil quality and non-target soil organisms, with studies identifying the depletion of macro-invertebrates and the disappearance of sensitive taxa downstream and in soils adjacent to flower-producing areas.
The consequences for long-term soil fertility are severe. Intensive pesticide use disrupts the microbial communities on which soil health depends. Repeated applications of synthetic fertilisers, often at rates calibrated for maximum bloom production rather than soil maintenance, produce short-term yields while depleting organic matter over time. Research on intensive cultivation has found that within the first 50 years of tilling, 40 to 70 percent of the original store of soil organic matter and nitrogen is lost — and for porous soils that begin with relatively low organic matter, the loss of fertility can be so severe that the land cannot be sustainably farmed at all. Flower farms tend to operate on exactly these highland soils: shallow, volcanic, high-yielding in their natural state, and vulnerable to rapid degradation under chemical-intensive monoculture.
In Kenya, croplands lose an average of 26 tonnes of soil per hectare annually to water-induced erosion, with some areas experiencing losses exceeding 90 tonnes — and over 85 percent of soils across East Africa are nutrient-deficient, with 75 percent of Kenyan soils falling below sustainable thresholds. Flower farming does not cause all of this damage, but it concentrates its operations in precisely the highland zones where soil degradation is most consequential and hardest to reverse, and its chemical inputs accelerate processes that were already underway.
The industry also generates solid and liquid waste streams that have no analogue in traditional agriculture. Flower farms in Ethiopia were found to use ineffective soak-away pits to dispose of liquid wastes, meaning that pesticide-laden effluent percolates into the soil rather than being contained or treated. The cumulative loading of persistent organic chemicals in soils adjacent to long-established farms is a problem that has received almost no systematic attention from regulators — in part because the monitoring infrastructure required does not exist, and in part because the governments most affected have had other priorities.
The Monoculture Trap
There is a second, subtler form of soil damage that the industry inflicts, one that operates not through chemical contamination but through structural simplification. Floriculture is, almost by definition, a form of extreme monoculture. A single farm growing only roses, year-round, under glass, with inputs calibrated to optimise one output variable — the bloom — is the agricultural equivalent of a factory floor. It has nothing in common with the mixed farming systems it displaces.
Those mixed systems — teff with legumes in Ethiopia, maize with beans and cassava across East Africa, polycultures of vegetable crops on the Colombian savanna — were not merely traditional in the sentimental sense. They were ecologically functional. Legume intercropping replenishes nitrogen. Root crop diversity breaks disease cycles. The rotation of crops with different nutrient demands prevents the progressive depletion of any single element. Over the last two decades, small farmers across Central and South America, Africa, and Asia have been pressured — through a combination of land enclosure, credit conditionality, and the collapse of local food prices caused by subsidised imports — to switch from diverse traditional polycultures to monocultures for overseas markets, a process researchers have characterised as systematic impoverishment.
When a flower farm displaces a polyculture smallholding, it does not merely replace one set of plants with another. It replaces a self-regulating ecological system with a chemically dependent one — and when the chemically dependent system eventually moves on or fails, it leaves soil that no longer contains the microbial diversity, organic matter, or structural integrity to support the polyculture that preceded it. The land has been simplified in a way that may take decades to reverse, if it can be reversed at all.
The Food Security Arithmetic
The land-food nexus plays out in two connected ways: direct displacement of food production from occupied plots, and the broader regional food security effects when prime agricultural areas are dominated by export horticulture.
Floriculture industries produce non-edible agricultural products for the global market, while smallholder farmers produce edible agricultural products for domestic consumption and contribute directly to national food security. This is not a rhetorical contrast. It is an empirical one. When land that could grow maize, teff, or beans instead grows roses, the food that would have been produced does not appear elsewhere in the local economy. It may, theoretically, be imported — funded by the foreign exchange the flowers have earned. In practice, in countries with food import infrastructure as fragile as Ethiopia’s or Kenya’s, the substitution is rarely clean. The foreign exchange may be captured by the government or by export firms, rather than flowing to the rural communities whose food production has been displaced.
Africa’s 33 million smallholder farms contribute up to 70 percent of the food supply in many countries, and the overwhelming majority of those farms operate on land that is classified as arable and well-suited to food production — the same classification that attracts floriculture. When that land shifts from food to flowers, the impact on national nutrition is not simply a matter of aggregate calorie production. It is felt immediately and locally: in the village market where less food is for sale, in the household that can no longer supplement its diet with its own production, in the child whose family has become dependent on wages that fluctuate with the European flower calendar.
A scoping study on Dutch flower farms in Eastern Africa found that employment opportunities created by floriculture often benefit migrant workers rather than locals, leading to increased competition for housing and food resources and further pressuring local communities. This adds a further dimension to the food security calculus: the industry does not merely displace local food production, but in some cases imports labour from elsewhere, concentrating the disruption without distributing the gains.
The Counter-Argument and Its Limits
The industry’s defenders make several points worth taking seriously. The most compelling concerns the counterfactual. In many of the regions where flower farms have expanded, the alternative to floriculture was not thriving smallholder agriculture. It was degraded land, poorly capitalised farms producing subsistence yields, and chronic rural underemployment. The greenhouses arrived not in a pastoral Eden but in places already suffering from soil exhaustion, population pressure, and lack of investment.
Research in Uganda found that 76 percent of flower farm workers reported a positive change in their economic conditions, with women workers in particular expressing that their economic status had improved as a result of employment on flower farms. This is a real finding, and it complicates the narrative of pure harm. It is possible to simultaneously acknowledge that flower farming has improved individual household incomes and that it has degraded the collective agricultural resource base on which those same households depend in the medium term.
The same scoping study that documented displacement also identified a potential model through outgrower schemes in Kenya, where smallholder farmers engaged directly with flower companies demonstrated that floriculture could enhance rather than undermine local food production. These schemes, in which commercial farms contract with smallholders to grow certain flower varieties on their own land, represent a genuine alternative to the enclosure model — one that keeps land in the hands of communities, maintains mixed farming systems, and shares the export premium more broadly. They exist. They work. They remain a small fraction of the industry.
The deeper limit of the economic defence is temporal. The returns to flower farming are real and present. The costs of soil degradation, nutrient depletion, and the loss of agricultural biodiversity are real but deferred — they accumulate in the soil over years and decades before becoming visible in declining yields. A government measuring export earnings this quarter has every incentive to approve another greenhouse development. The farmer whose grandchildren will try to grow food in that soil has no say in the matter.
What the Soil Remembers
There is an asymmetry at the heart of the problem that no amount of corporate social responsibility can fully address. The soil takes centuries to form and years to destroy. Microbial communities, once disrupted by persistent pesticides, do not reconstitute themselves in a single growing season. Organic matter, stripped by intensive monoculture, requires sustained investment of time, compost, and restraint to rebuild. The highlands of Kenya and Ethiopia and Colombia are, in geological terms, exceptional — young volcanic soils with a fertility that has supported human agriculture for millennia and that other countries, with older and more degraded soils, would not be able to replicate.
Soil erosion, nutrient imbalances, acidification, and compaction are the dominant forms of land degradation across Africa, with cascading consequences for food security, carbon storage, ecosystem services, and human health. The floriculture industry did not create these problems. But it concentrates its operations in the places where healthy soil still exists, applies the practices most likely to degrade it, and leaves behind a legacy of chemical loading and structural simplification that outlasts any individual firm.
Forests are cleared, swamps drained, rivers diverted, and whole villages moved to make way for commercial agricultural projects, with investors noting that the land is “very good” and “quite cheap” — a combination that has historically been the precondition for extraction, not stewardship. That observation applies as directly to floriculture as to any other form of large-scale export agriculture in developing countries. The goodness of the land and its cheapness are inversely related to the care with which it is used.
The flowers will keep arriving in European cities, wrapped in cellophane, bearing certification labels of varying credibility. The land they came from will keep absorbing the consequences. At some point, the balance sheet that only counts export earnings will have to be reopened — and the soil’s account will need to be settled.
