Indonesia's National Disaster Mitigation Agency (BNPB) said on December 18 that the La Nina weather pattern will strengthen from mid-2016, citing data from the country's weather agency.
"Rain volume during 2016 will increase, causing floods and landslides," said Sutopo Nugroho, spokesman of BNPB.
La Nina is a cooling of the tropical waters of the Pacific that is a counterpart to the El Nino weather event that is characterised by warmer waters. El Nino typically has knock-on effects that can cause billions of dollars of damage to food and water supplies around the globe.
