In West Kalimantan on the island of Borneo that Indonesia shares with Malaysia and Brunei, the mayor of Pontianak ordered schools closed due to the smoke wafting over the city from fires elsewhere.Public records show Pontianak has tens of thousands of public school pupils.Children will learn from home for as long as air quality remains poor, mayor Edi Rusdi Kamtono said in a statement Monday, without stating how many schools were affected."We have started to feel it, especially at night and in the morning, as haze has already blanketed the city of Pontianak," he said.On the island of Java, firefighters battled flames for a ninth day at a national park that has lost 900 hectares to an inferno that broke out on Monday last week.The blaze at the Bromo Tengger Semeru National Park, a major tourist attraction closed to visitors since Saturday, is one of several wildfires that have drawn in nearly 50,000 firefighters countrywide.Indonesia is forecast to experience an unusually tough dry season this year with high risk for drought and wildfires due in part to the El Nino weather phenomenon, the BMKG weather agency has said. More than 107,000 hectares of land have burnt countrywide so far this year.Authorities insist that food stocks remain adequate. Hot JulyThe fire at the Bromo park in East Java has consumed nearly 900 hectares, or more than 2,200 acres, by Tuesday morning.This is equivalent to over 1,200 football fields and nearly two percent of the total park area."We’re making our best effort and mobilising everything... to extinguish and wet-down the area," local disaster official Satriyo Nurseno told AFP."We hope that today we can put out the fire in all areas, then carry out soaking so that the fire does not reignite." Three water-bombing helicopters and fire trucks were providing support to about 200 firefighters, forest rangers, police and soldiers helping to put out the blaze.
