TOKYO, Japan, 27 November 2025 (Guardian) - Jakarta has overtaken Tokyo as the world’s most populous city, according to a UN study that uses new criteria to give a more accurate picture of the rapid urbanisation driving the growth of megacities. The Indonesian capital is home to 42 million people, according to an estimate by the population division of the UN Department of Economic and Social Affairs in its World Urbanisation Prospects 2025 report published this month.

COLOMBO, Sri Lanka, 26 November 2025 (Mongabay) - In Sri Lanka’s southern district of Hambantota, authorities have launched a large-scale elephant drive, mobilizing wildlife officers, armed forces and villagers to push herds from villages into what is known as the Managed Elephant Reserve (MER). Conservationists warn the Hambantota operation could mirror past failed drives, such as the 2006 drive in the south and the 2024 operation in north-central Sri Lanka that left elephant herds stranded.
