The Ethiopian Banana: Can Enset Help Solve Climate and Hunger Crises?
Exploring how Ethiopia's enset, known as the 'tree against hunger,' could bolster global food security in a changing climate.
The Enset: Ethiopia’s ‘Tree Against Hunger’
Amidst mounting global concerns about food security and climate resilience, a little-known Ethiopian crop called enset, or the ‘false banana,’ is gaining international attention. Indigenous to the Ethiopian highlands, enset has fed people for millennia, earning its reputation as the ‘tree against hunger.’ Unlike conventional bananas, enset is not commonly known outside Ethiopia, yet it holds extraordinary promise for a warming world facing unprecedented agricultural challenges.
What Is Enset?
Enset (Ensete ventricosum) is a perennial crop from the banana family, distinguished more by its underground corm and pseudostem than by its small, inedible fruit. Despite being referred to as a ‘banana,’ enset is not cultivated for its fruit but for its starchy trunk and roots. In regions of Ethiopia where enset is a staple, it is processed into foods like kocho (a fermented flatbread) and bulla (a porridge), which nourish more than 20 million people during both regular cycles and times of crisis.
- Deep Cultural Integration: Enset’s cultivation and processing are woven deeply into Ethiopian culture, tradition, and diet.
- Climate Resilience: The plant tolerates erratic rainfall, drought, and poor soils, thriving where other crops fail.
- Famine Food: Unlike many crops, enset is not subject to strict harvest timings. It can be left in the ground and harvested as needed, functioning as a living food bank.
Food Security Challenges: Bananas and the Global Diet
Bananas are among the most consumed fruits worldwide and form a dietary staple for hundreds of millions. However, the world’s reliance on a narrow range of banana cultivars—primarily the Cavendish—is exposing global food security to severe threats:
- Climate Change: Rising temperatures, extreme weather, and shifting rainfall patterns are undermining banana yields and suitability in current growing regions.
- Disease Vulnerability: Monocultures of Cavendish bananas are especially susceptible to devastating diseases such as Panama disease (Tropical Race 4).
- Sustainability Concerns: The extensive pesticide use and water demand in commercial banana plantations raise serious environmental and social issues.
These challenges have profound implications for tropical agriculture and the hundreds of millions of people who rely on bananas for daily sustenance and income.
Rising Pressures: Climate Change and Crop Risk
Shifts in climate patterns are pushing traditional crops beyond their thermal, hydrological, and disease tolerance limits.
- Bananas thrive between 15–35°C and need high humidity; extreme temperatures above 38°C or below 12°C, droughts, and storms halt growth, cause injury, or destroy crops entirely.
- The United Nations Food and Agriculture Organization warns that by 2050, key exporters such as Colombia, Costa Rica, India, and Brazil will see diminishing banana yields and losses in suitable land for banana cultivation.
- Extreme weather—like cyclones—can devastate entire plantations, while fungal outbreaks are spreading faster in the hotter, wetter climates fostered by climate change.
Direct VS Indirect Impacts
| Type of Impact | Examples | Relevant Crops |
|---|---|---|
| Direct | Droughts, floods, temperature extremes damaging plants or halting growth | Banana, Maize, Wheat |
| Indirect | Spread/evolution of diseases and pests, soil degradation | Banana, Coffee, Cocoa |
As a result, the search for resilient, diverse crops that can secure future food supplies is intensifying.

Enset’s Unique Climate Advantages
Enset offers critical advantages over conventional bananas and many staple crops:
- Wide Climatic Tolerance: Grows across a range of altitudes and survives in both drought and heavy rainy seasons.
- Flexible Harvest: Can remain unharvested for years until needed, providing a continuous safety net in times of shortage.
- High Productivity: A single enset plant can produce enough edible material to support a family for months.
- Minimal Pest and Disease Issues: Historically, enset is cultivated with lower pesticide use and has shown greater resilience to plant diseases than bananas.
- Soil Conservation: Enset’s extensive root network protects against erosion, helps preserve water, and stabilizes hillsides, further enhancing community resilience.
How Enset Is Cultivated and Used
Enset cultivation, primarily in Ethiopia, is a multi-step process rooted in indigenous innovation:
- Propagation: The plant is usually propagated vegetatively through corms rather than seed, supporting genetic consistency.
- Harvest & Processing: After three to seven years, enset is harvested by stripping the pseudostem and corm for its starchy fibers, which are then fermented underground to produce staple foods.
- Byproducts: In addition to food, enset leaves and stalks are used for animal feed, packaging, construction material, and more, generating zero waste.
- Cultural Value: Enset patches are traditionally tended by households, and processing know-how is predominantly maintained and passed down by women.
Why Hasn’t Enset Spread Beyond Ethiopia?
Despite its remarkable advantages, enset remains a predominantly Ethiopian crop. Several factors have limited its dissemination:
- Knowledge Barrier: Processing enset is labor-intensive and requires know-how not widely shared outside Ethiopia.
- Slow Breeding & Propagation: Unlike Cavendish bananas, global breeding programs are only beginning to develop improved enset varieties.
- Policy and Support: Historically, little research and investment has been channeled into ‘orphan crops’—crops neglected by global agricultural R&D despite their local importance.
Enset as a Model for Climate-Adapted Crops
Recent international research is beginning to change this picture. Scientists are studying enset’s genetic diversity and identifying regions across Africa with suitable conditions for the crop. Modeling indicates that enset could be cultivated across wide swathes of Eastern and Southern Africa, potentially providing a new food security buffer to tens of millions more people.
Potential benefits of scaling up enset include:
- Reducing dependence on single-crop systems and the risks associated with monoculture.
- Offering smallholder farmers a climate-resilient alternative that fits diverse landscapes.
- Contributing to sustainable rural livelihoods and landscape restoration.
Challenges and Limitations
Although the promise is real, the expansion of enset is not without challenges:
- Processing Skills: The unique and labor-intensive methods of harvesting and fermentation are not easily transferable to new regions without significant training and adaptation.
- Disease Risks: Introducing a crop to new environments requires careful phytosanitary control to avoid unintended pathogen spread or new disease challenges.
- Market Development: As with any emerging crop, building demand, supply chains, and farmer incentives will take time and investment.
Policy and Research Recommendations
- Increase funding for research on orphan crops like enset, including breeding for disease resistance and improved yield.
- Build local and regional knowledge-sharing networks, particularly female-led farmer extension services.
- Support pilot projects in other African nations with similar climates to test local suitability and cultural acceptability.
- Integrate enset into broader climate and food security strategies at national and international levels.
Other Underutilized Crops with Promise
Enset is just one example of the hundreds of so-called ‘orphan’ or ‘forgotten’ crops that may hold keys to resilient food systems as conditions shift. Other candidates include:
- Millets and Sorghum: Drought-resistant grains with high nutritional value, grown across parts of Africa and India.
- Taro and Cassava: Robust root crops capable of thriving under stress.
- Bambara groundnut and Teff: Staple legumes and grains adapted to poor soils and erratic rainfall.
By broadening the global agricultural toolkit beyond a few major staples, scientists and policymakers believe food systems can become more resilient, adaptable, and ultimately, more nutritious and equitable.
