El Jable is one of the most fascinating natural landscapes of Lanzarote, the easternmost island of the Canary archipelago. Often described as a “sea of sand” flowing between volcanic mountains, it stretches from the northwest to the southeast of the island, creating an otherworldly terrain that combines desert-like dunes, fertile agricultural zones, and unique ecosystems. While at first glance El Jable appears barren, it has long been a source of sustenance, mystery, and resilience for the people of Lanzarote. The word jable itself refers to a light, mobile volcanic sand that plays a vital role in the island’s soil fertility and microclimate. Unlike typical desert sands, jable originates from the erosion of volcanic rocks and marine sediments, giving it a composition rich in minerals that nurture plant life in an otherwise arid environment.
Understanding El Jable means understanding the identity of Lanzarote itself. The region tells a story of adaptation—how people have learned to work with the land, rather than against it. It represents a delicate balance between natural processes and human effort, where sustainable farming, biodiversity conservation, and cultural heritage intertwine.
Geographical Location and Extent
El Ja-ble occupies a large portion of central Lanzarote, roughly between the towns of Famara on the northwestern coast and Soo, Tiagua, San Bartolomé, and Guatiza toward the eastern and southern regions. This area covers nearly one-fifth of the island’s surface, making it one of its defining geographical features. It forms a vast corridor of pale golden sand stretching across volcanic plains and between ridges of basaltic rock.
Below is a simplified representation of its geographical reach:
| Area | Approximate Coverage (km²) | Main Towns or Landmarks |
|---|---|---|
| Northwestern Zone | ~20 | Famara, La Caleta, Soo |
| Central Plains | ~35 | Tiagua, Tao, Muñique |
| Southeastern Edge | ~15 | San Bartolomé, Mozaga, Guatiza |
| Total | ~70 km² | — |
The winds that blow from the Atlantic Ocean carry fine sand particles from Famara Beach inland, creating slow but continuous dune migration. These winds are crucial to El Ja-ble’s formation, as they constantly reshape the surface while replenishing the sand that nourishes the soils beneath. The interaction between the Atlantic breezes, volcanic topography, and human use makes El Jable a living geological system.
Origin and Geological Composition
El Ja-ble was formed through a combination of volcanic activity, marine sedimentation, and aeolian (wind-driven) processes. Over thousands of years, eruptions on Lanzarote produced immense quantities of volcanic ash and lapilli—tiny fragments of solidified lava. Ocean currents and wave action broke down coastal rocks and shells into calcareous sand. Trade winds then carried this material inland, depositing it across the island’s lowlands and valleys.
The result is a unique geological mix of bioclastic and volcanic sand, different from the silicate sands of continental deserts. The composition typically includes:
| Component | Percentage Range | Origin |
|---|---|---|
| Volcanic ash (lapilli) | 40–60% | Volcanic eruptions |
| Calcareous sand | 20–30% | Marine shells and coral fragments |
| Basalt dust | 10–20% | Erosion of volcanic rock |
| Organic material | 1–5% | Decomposed vegetation |
Because of this composition, El Jable’s sand has exceptional moisture-retaining properties. Despite Lanzarote’s low annual rainfall (less than 150 mm per year), the jable acts like a sponge—trapping dew and condensation, which slowly percolate to the soil below. This natural mechanism creates micro-reservoirs that make agriculture possible in what would otherwise be desert land.
Climate and Environmental Conditions
The climate of El Jable is governed by the trade winds, the Canary Current, and the subtropical position of the island. Temperatures remain mild throughout the year, averaging 20–25°C, with very little seasonal variation. The main challenge to vegetation is not temperature but the lack of rainfall and the constant evaporation caused by wind.
Humidity levels fluctuate but are generally moderate due to marine influence. Morning mists, known locally as calima, bring fine dust and moisture from the Atlantic and North Africa. These mists often deposit water droplets on the jable surface, helping to sustain vegetation and prevent the sand from drying completely.
In ecological terms, El Jable represents a semi-arid environment, yet its delicate balance of sand, wind, and humidity supports a surprisingly rich ecosystem.
Flora of El Jable
At first glance, El Jable may appear devoid of plant life, but closer inspection reveals an extraordinary diversity of species adapted to survive under extreme conditions. The vegetation here consists mostly of xerophytic (drought-resistant) plants that can store water or absorb it quickly after dew formation. Many species are endemic—found only in the Canary Islands or even just in Lanzarote.
Some of the characteristic plants include:
| Common Name | Scientific Name | Notable Adaptation |
|---|---|---|
| Sea Lettuce | Astydamia latifolia | Thick leaves store water and resist salt spray |
| Canary Spurge | Euphorbia balsamifera | Produces latex sap and reduces transpiration |
| Jable Clover | Trifolium webbianum | Grows in sandy soils and fixes nitrogen |
| Sand Daisy | Asteriscus intermedius | Forms low mats to resist wind erosion |
| Tabaiba | Euphorbia regis-jubae | Typical of semi-desert volcanic soils |
In agricultural zones of El Jable, humans have further diversified the flora by cultivating crops such as sweet potatoes, melons, pumpkins, onions, and cereals, using traditional methods that rely on the sand’s moisture-preserving capacity.
Fauna and Biodiversity
El Jable is also home to several rare and endangered species, particularly birds that depend on its open, undisturbed spaces for nesting. The Canary Houbara Bustard (Chlamydotis undulata fuertaventurae), a large ground-dwelling bird, is the most iconic inhabitant of this region. This bird is endemic to the eastern Canary Islands and is considered a symbol of Lanzarote’s wildlife.
Other bird species that thrive in the jable include Stone Curlew (Burhinus oedicnemus distinctus), Cream-colored Courser (Cursorius cursor bannermani), and various larks and shrikes. Reptiles, particularly the Atlantic Lizard (Gallotia atlantica), are also common and play a key role in maintaining ecological balance.
Insects adapted to arid climates, such as sand beetles, ants, and butterflies, contribute to pollination and decomposition cycles. Though mammals are few, introduced species like rabbits and goats sometimes influence vegetation patterns. Conservationists monitor these populations to maintain the equilibrium between agriculture, tourism, and biodiversity.
Cultural and Historical Significance
El Jable’s importance extends far beyond geology and ecology—it has shaped the culture and traditions of Lanzarote for centuries. Historical records suggest that the indigenous Majos, the island’s original inhabitants, used the fertile jable valleys for grazing and limited cultivation. After the Spanish conquest in the 15th century, settlers began to exploit the sand’s agricultural potential more systematically.
During the 17th and 18th centuries, as volcanic eruptions devastated large portions of Lanzarote, the jable became a lifeline for food production. Farmers discovered that by planting crops directly into the sand, they could harness its moisture-trapping ability. This gave rise to the “agricultura en jable” or jable farming system—a remarkable example of human ingenuity in adapting to harsh conditions.
Traditional jable farmers used hand tools to create small depressions in the sand, where seeds were sown and covered lightly. The plants grew using only the humidity captured overnight. This low-input, sustainable technique ensured food security for generations and remains an essential part of Lanzarote’s agricultural heritage today.
Agriculture in the Jable: A Sustainable Legacy
The jable farming system is not only an agricultural practice but also a cultural treasure recognized for its sustainability and efficiency. Modern agronomists often study it as a model for dryland farming in arid regions worldwide.
| Crop | Local Variety | Growing Season | Main Uses |
|---|---|---|---|
| Sweet Potato (batata) | White and red varieties | Spring–Summer | Food, traditional dishes |
| Pumpkin (calabaza) | Local orange type | Summer–Autumn | Cooking, livestock feed |
| Melon (melón de jable) | Small and aromatic | Summer | Fresh consumption |
| Onion (cebolla de Lanzarote) | Sweet variety | Winter–Spring | Culinary export |
| Barley (cebada) | Traditional cereal | Winter | Animal feed, local beer |
Farmers working in the jable often rely on ancestral knowledge passed down orally, emphasizing observation of wind direction, humidity levels, and lunar cycles. Their fields require no irrigation, no chemical fertilizers, and minimal soil disturbance—qualities that make jable agriculture exceptionally sustainable and environmentally friendly.
