Walipini

Wikipedia stub defining walipini as an earth-sheltered cold frame named from Aymaran languages, linking Benson 2002 PDF, pineapple pits, Soviet citrus trenches, and permaculture interest in passive heating. Defines walipini as an earth-sheltered cold frame deriving its name from Aymaran languages. States it is similar in concept to Victorian British pineapple pits and pre-revolution Russian / Soviet citrus growing techniques; cites Low-tech Magazine fruit trenches claim of 30,000 ha Soviet citrus by 1950 producing 200,000 tonnes/year. Notes attractiveness to permaculture/sustainability because crops can be grown greenhouse-like with little to no heating.
