Cuba’s Urban Farming Shows Way to Avoid Hunger
By Paul Brown
When countries run short of food, they need to find solutions fast, and one answer can be urban farming.
That was the remedy Cuba seized with both hands 30 years ago when it was confronted with the dilemma of an end to its vital food imports. And what worked then for Cuba could have lessons today for the wider world, as it faces growing hunger in the face of the climate crisis.
When the Soviet Union collapsed in the 1990s, most of Cuba's food supplies went with it. To stave off severe malnutrition the people of the capital, Havana, found an imaginative answer: urban gardening. That's now seen as a possible blueprint for the survival of city populations in a warming world.
The Rapid Transition Alliance has published a longer account of Cuba's very fast move towards self-sufficiency as part of its series Stories of Change, which describes cases of large-scale, rapid transformation that can seem difficult to achieve but which have often worked before.
The problem of hunger for the Cubans arose because during the Cold War they had stopped producing food of their own and turned over most of their farmland to sugarcane plantations to supply the Soviet Union. In return for these mountains of sugar Moscow provided Cuba with food, chemical fertilizers and fuel oil for its cars and tractors.
The Soviet collapse brought the breakdown of this trade, and food rationing for city dwellers. And Cuba lost its main food supply while it was still coping with strict U.S. sanctions. Reverting to conventional farming would have taken time and was in any case difficult because the Soviet fertilizers, fuel and pesticides had also dried up.
So the highly-educated urban citizens, faced with rationing which reduced the average Cuban's daily calorie intake from 2,600 in 1986 to 1,000-1,500 in 1993, organized themselves to grow their own food in improvised urban allotments.
At first, struggling with little know-how and without fertilizers, their yields were low, but by producing compost and other organic growing mediums, plus introducing drip-fed irrigation, they began to see improvements.
Short of chemicals, the gardeners resorted to biological controls like marigolds (where opinions today are mixed) to deter harmful insects.
By 1995 Havana alone had 25,000 allotments tended by families and urban cooperatives. The government, realizing the potential benefits, encouraged the movement.
Soil quality was improved with a mixture of crop residues, household wastes and animal manure to create more compost and soil conditioners. The extra fresh vegetables and fruit this provided quickly improved urban dwellers' calorie intake and saved many from malnutrition.
In the Cuban climate, with irrigation changes and soils undergoing constant improvement from added organic matter, the allotments could produce vegetables all year round. Lettuce, chard, radish, beans, cucumber, tomatoes, spinach and peppers were grown and traded.
There is evidence as well that the extra exercise which these urban gardeners got from tending their allotments, plus the time they spent outdoors in the open air, benefited their health.
Eventually, realizing that self-sufficiency was the only way to feed the population, the government banned sugarcane growing altogether. Lacking fertilizer, many former plantations were turned over to organic agriculture. The shortage of oil for tractors meant oxen were used for ploughing.
Cuba's experience of urban agriculture inspired many environmentalists to believe that this is at least part of the solution to the food shortages threatened by climate change. By 2008 food gardens, despite their small scale, made up 8 percent of the land in Havana, and 3.4 percent of all urban land in Cuba, producing 90 percent of all the fruit and vegetables consumed.
As a result the calorie intake of the average Cuban quickly rose to match that of Europeans, relying on a diet composed mainly of rice, beans, potatoes and other vegetables — a low-fat diet making obesity rare.
Because of the climate, though, wheat does not grow well in Cuba, and the island still has to import large quantities of grain for bread. Meat is in short supply and also has to be mainly imported.
Despite this, Cuba's experience since the Cold War ended in the 1990s shows that large quantities of fresh food can be grown in cities and that urban agriculture is sustainable over decades.
For other countries vulnerable to sudden loss of food supplies, Cuba's experience suggests that urban farming can be one way of staving off potential famine when imports are restricted, expensive or simply unobtainable.

Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>
