Climate change is increasingly threatening the handful of regions that supply the world’s cut flowers, exposing vulnerabilities in an industry built on stable, predictable climates. From East Africa’s water-stressed rose farms to the Netherlands’ energy-intensive greenhouses, producers are grappling with shifting weather patterns, rising costs, and supply-chain disruptions that could reshape flower availability and prices worldwide.
East Africa: Water Scarcity Looms Over Rose Production
Kenya, the world’s fourth-largest cut-flower exporter and supplier of roughly one-third of all roses sold in the European Union, centers its industry around Lake Naivasha. The region’s high altitude, abundant sunshine, and reliable water made it ideal for year-round cultivation. But recurring droughts are now straining the lake and surrounding aquifers, intensifying competition among flower farms, fishing communities, and food growers. Water access has overtaken land or labor as the sector’s biggest long-term risk, according to industry analysts.
Ethiopia, a smaller but rapidly growing producer accounting for about 2% of global cut-flower sales, faces a similar dynamic. Its floriculture sector has created more than 100,000 jobs—most held by women—but depends on the same water-intensive, climate-vulnerable model. Both countries are investing in efficient irrigation and water recycling to protect a key source of foreign revenue.
South America: Andean Growers Face Weather Volatility
Colombia, the world’s largest cut-flower producer, exports hundreds of millions of stems annually—primarily to the United States. Farms cluster near Bogotá’s international airport to minimize transit time, as flowers can lose roughly 15% of their value for each extra day in shipping. Any weather-related disruption to harvests or logistics has an outsized impact on the supply chain.
Ecuador, known for its large, high-altitude roses grown in industrial greenhouses, is also feeling the strain. Shifting rainfall patterns exacerbate water stress in a system already criticized for heavy chemical use. Combined with labor and environmental concerns, climate-linked water shortages threaten the region’s dominance in the U.S. market, particularly during peak demand periods like Valentine’s Day and Mother’s Day.
The Netherlands: Energy Transition Pressures Greenhouse Industry
The Netherlands remains the global epicenter of flower trade—the top exporter and re-export hub for African blooms reaching Europe. Unlike equatorial producers, the Dutch challenge is not water but energy. Its cold, cloudy climate requires greenhouse heating and supplemental lighting powered largely by fossil fuels. Studies show that roses grown in Dutch greenhouses can generate several times the emissions of those grown outdoors in Kenya, even after accounting for air freight. Rising energy costs and climate policies are pushing growers toward geothermal heating, improved glazing, and renewables—changes driven by economics as much as by weather.
United Kingdom: Import Reliance Poses Climate Risk
Britain imports about 90% of its cut flowers, leaving it heavily exposed to climate disruptions abroad. A recent Nuffield Farming report found that UK growers focused mainly on cutting carbon emissions while neglecting domestic resilience against extreme heat, flooding, and drought. Growing interest in home-grown blooms—promoted by producer networks as a lower-carbon alternative—remains small, representing only about 10% of the £2.2 billion market.
United States: Drought Strains Domestic Farms, Import Dependence
California’s flower industry, once among the largest in the country, faces worsening drought and water restrictions that raise production costs. However, the United States imports the majority of its cut flowers from Colombia and Ecuador, making American consumers indirectly vulnerable to climate pressures in the Andes. A modest resurgence in domestic, often smaller-scale flower farming is partly framed as a way to reduce exposure to that long, climate-risky supply chain.
Southern Europe: Mediterranean Water Conflicts
In Spain, Portugal, and other Mediterranean regions, water-intensive flower and ornamental plant production competes directly with traditional agriculture as droughts become more frequent. The same stress reshaping berry cultivation under plastic greenhouses is now squeezing flower growers in some of Europe’s driest areas.
Common Challenges Ahead
Despite regional differences—water scarcity in East Africa and the Andes, energy in the Netherlands, drought in California and southern Europe—flower-growing regions worldwide face converging pressures: unpredictable seasons, rising pests and diseases, and the high cost of protecting a perishable, low-margin product against volatile weather. An industry that flourished by exploiting stable climates must now adapt to a future where that stability can no longer be assumed. For consumers, the likely outcome is higher prices and less predictable supply, especially during peak floral holidays, as producers scramble to invest in resilience or risk losing their place in the global market.
