Patrol the Leuser Ecosystem with Forest Defenders at HAkA

Ask a Question

  • This article and video are about the efforts of an Indonesian organization, HAkA, to protect the Leuser ecosystem, what this ecosystem provides, and the challenges this organization faces while defending the Leuser ecosystem. 
  • Students will see the technology HAkA uses in their efforts, such as satellite imagery and alerts from Global Forest Watch to monitor deforestation in this ecosystem.
Teaching Tips


  • The article is concise and easy to understand.
  • The demonstration of the technology in the video is engaging and interesting.

Additional Prerequisites

  • Students need to know what a carbon sink is and how it affects climate change.
  • Students need to understand the importance of biodiversity.


  • This video can enhance a lesson on the economic incentives that lead to worldwide deforestation.
  • This video can support a lesson on how human population size and the management of natural resources are linked.
  • Students can research other forests that are carbon sinks and how to maintain them.
  • After watching the video, the teacher can lead a classroom discussion on the importance of conserving ecosystems worldwide.
  • This video has closed captioning, but the captions are often inaccurate. Students who struggle to understand the video may benefit from slowing the playback speed.
Scientist Notes
This video introduces the Leuser region in Indonesia and discusses the challenges it currently faces with deforestation. The video also discusses how scientists and forest workers use satellite data to monitor deforestation and why it is valuable data in addition to data from the field. The video includes many graphics of maps and satellite technology. The narrator briefly mentions the idea of sharing data and open data access. Overall, this resource is a concise introduction to remote sensing research, its uses, and the importance of ecosystems. The information is accurate, and this video is recommended for teaching.
