3 Main Causes of Floods in Indonesia and How to Prevent

Jul 31, 2019 Extreme Weather. High intensity of rainfall (generally more than 100 mm per day) for long stretches of time often contributes to flooding in Indonesia. Daily rainfalls of 248.5 mm, 110-197 mm and 182-289 mm were recorded in Jayapura Regency in Papua, South Sulawesi and Bengkulu, respectively, when floods and landslides hit those regions

Mining industry and sustainable development: time for

Jun 09, 2017 Mining industries provide many of the raw materials for equipment we use daily, from aluminum cans up to electronic chips of cell phones and computers. To arrive here, metal mining steadily increased over the centuries, with occasional “rushes” for several minerals (silver, gold, radium, etc.) which occurred in connection with booms in demand
