Researchers from the Israel Antiquities Authority and Tel Aviv University have uncovered fortifications that help reassess the limits of the ancient city of Jerusalem. Archaeologists, with the help of drones and Google Earth imagery, have discovered 4,000-year-old canals in Belize that were once used by the predecessors of the ancient Mayans to catch freshwater fish. "The aerial imagery was crucial to identify this really distinctive pattern of zigzag linear canals" study co-author Eleanor Harrison-Buck of the University of New Hampshire said of the pre-Christopher Columbus discovery. The fish-trapping canals, built around 2000 BCE, continued to be used by their Mayan descendants until around 200 CE. Altar Q that depicts 16 kings in the dynastic succession of the city is seen inside the archeological site of Copan, in Copan Ruinas, Honduras.

Belize has long struggled to control illegal fishing both in its waters and by vessels flagged to its country. But efforts to turn the tide are starting to pay off, says Julio Maaz, who serves as a fisheries coordinator in the country with the nonprofit group Wildlife Conservation Society. In March 2014, the European Union suspended all seafood imports from Belize, saying the country had not acted forcefully enough to prevent illegal fishing, also known as pirate fishing. But the country responded by upping its enforcement activities (including by deploying the coast guard), and the European Union restored its trade relationship by the end of that year. Further progress has been made since then, but the country still has a ways to go, says Maaz. Belize's multimillion coastal fishing industry is made up of 2,700 registered fishermen, with 650 vessels.
