Getting by without petroleum or petroleum-based products (fertilisers and pesticides, for example) forced the largest and most compressed experiment in organic and urban gardening in history. The early 1990s saw the creation of 26,000 public gardens in Havana alone, turning the city into a big urban farm that supplied enough produce for about half of its nutritional needs. Although the notion will surely horrify work-shy futurists, the substitution of labour intensity for power intensity is in itself not a bad thing. If half-earthing were ever implemented, agriculture could usefully soak up unemployed workers from defunct industries that were dependent on high fossil-fuel consumption. During the Período Especial, Cuba bought over a million bicycles from China to replace the idle buses and cars. Eating less meat and more vegetables, combined with cycling or walking to work generally led to improved health in the general population. Plantation monocultures could not be managed without massive fossil-fuel inputs, so Cubans cultivated less land more intensively, returning about a third of farmland to wilderness. This has helped Cuba maintain its incredible biodiversity (indeed, it is listed amongst Wilson’s global hotspots) and led the World Wildlife Fund to recognize it as the world’s only ‘sustainable’ country. With its effective and low-cost social policy and post-fossil fuel economy, the experience of Cuba in the 1990s offers the outline of a feasible, eco-egalitarian half-earth society.
