This post examines how an emergent drought in Maine—driven by broader patterns of climate change—is affecting the state’s vital potato industry, alongside other crops like blueberries. I explain the immediate impacts, practical responses on farms, and longer-term strategies needed to protect staple crops, drawing on reporting from Aroostook County and input from scientists and growers.
Dry fields and shrinking tubers: what’s happening in Maine
Three-quarters of Maine are currently flagged as dry, with southern regions slipping into moderate to severe drought conditions by the U.S. Drought Monitor. In Aroostook County—the heart of the state’s potato production—rainfall this season has been well below normal and growers are watching plants fail in the most critical growth stage.
On-the-ground realities for potato growers
Seed potato grower Daniel Corey described fields as “bone dry”. Many plants are wilting by midday.
Farms with irrigation are running systems where possible, but most operations can only water portions of their acreage. The consequence is that tubers that do not receive adequate late-summer moisture remain undersized—directly reducing yields and ultimately raising consumer prices.
Key effects to watch:
Beyond potatoes: blueberries, ecosystems, and food chains
The stress is not limited to potatoes. Blueberry growers in both Maine and Canada have warned of substantial losses—Canadian producers estimate up to one-third losses in some areas—which will compound supply pressures.
Drought affects pollinators, soil health, and local gardens. This creates cascading impacts on rural communities that depend on diversified farm income.
Economic and ecological ripple effects
When staple crops decline, the shocks are felt far beyond the field. Retail prices for potatoes and berries can climb, food processors face raw-material shortages, and local labor markets are strained.
Drier soils and stressed vegetation can increase erosion and reduce habitat quality for native species.
Adaptation: what farmers and scientists are doing
Research teams at the University of Maine and other institutions are developing climate-resilient potato varieties and exploring best practices for soil moisture conservation. Farmers are experimenting with targeted irrigation, mulching, adjusted planting dates, and soil health practices that increase water retention.
However, these measures have limits when drought is extensive and prolonged.
Practical steps and long-term needs
On-farm responses can reduce exposure in the near term.
Meaningful resilience requires coordinated action across research, policy, and markets.
Policymakers, researchers, and supply-chain leaders must act together to fund resilient infrastructure and accelerate breeding programs.
Cutting emissions is essential to reduce the frequency and intensity of damaging events.
Otherwise, consumers should expect higher prices and communities will continue to shoulder the growing costs of climate-driven agricultural disruption.
