Today’s Solutions: July 16, 2025

The world of agriculture is shifting from its traditional methods of growing food to much more sustainable, efficient systems. London has a subterranean urban farm, Kyoto will soon have a hi-tech indoor “vegetable factory” and now two Italian architects have created a floating greenhouse called the Jellyfish Barge made of wood and recycled plastic that desalinates seawater to irrigate and grow plants. One module is 70 square meters (735 square feet), and can be combined together with others to make a floating farm, with each Jellyfish Barge producing up to 1,200 plants per month. Sustainable floating greenhouses could be a perfect solution for coastal areas affected by scarcity of food and fresh water, and other cities looking to get produce from a more local, sustainable source.
