Chair of IPB University Disaster Study Center Reveals Illegal Activities Behind Sumatra Disasters

Chair of the IPB University Disaster Study Center (PSB), Prof Bambang Hero Saharjo, revealed that there were illegal human activities behind various hydrometeorological disasters that occurred in Sumatra. 

“From media monitoring, it is clear that the forest area is open, without natural barriers. Tree cover is gone, the land is exposed, so rainwater flows directly downhill,” he said while speaking at the LRI TALK #3 event themed “Together Protecting Sumatra” (12/24).

Based on this data and facts, Prof Bambang confirmed that floods and landslides—often referred to as hydrometeorological disasters—are not solely caused by natural factors. 

“There are human activities behind them, both intentional and negligent. When these conditions are triggered by above-normal rainfall, disasters occur that claim lives, damage the environment and infrastructure, and cause suffering for many families,” he said.

He emphasized that those behind these illegal activities cannot escape legal responsibility. “They must still be held accountable and cannot be allowed to go free,” said Prof Bambang.

Furthermore, he explained that the loss of millions of hectares of forest due to illegal logging has caused land degradation and damaged the hydrological function of watersheds (DAS). This condition triggers irregular rainfall patterns, inconsistent rainy and dry seasons, and an increased risk of flooding and landslides.

He also highlighted the massive clearing of land for settlements, agriculture, and economic interests, which releases carbon reserves into the atmosphere and exacerbates global warming.

Prof Bambang explained the scope of the definition of forest destruction. In addition to illegal logging, forest destruction also includes the use of forest areas without permission, or the use of permits that are contrary to the purpose for which they were granted.

According to Law No 18 of 2013, illegal logging is defined as the unauthorized and organized exploitation of timber resources in forest areas designated by the government. (dh) (IAAS/RMH)
