Lesson Plan: Civilizations and Climate Vulnerability: The Khmer Empire

by TROP ICSU

As a High School or Undergraduate teacher of History or Social Sciences, you can use this set of computer-based tools to teach about civilizations, decline of civilizations or empires, and societal vulnerability to climate-related extreme events.

This lesson plan will help students to learn about Angkor and the Khmer empire—its history, the geographical boundaries, various rulers, the architecture and structures built during the period, culture (including religion and festivities), and possible reasons for the decline and demise of the empire, including climate-related extreme events. The activities will also help students to use 360 degree visualizations while learning about the significance of water and water systems in the life of the Khmer people.

Thus, the use of this lesson plan allows you to integrate the teaching of a climate science topic with a core topic in History or Social Sciences.

 A classroom/laboratory activity that uses 360 degree visualizations, readings, and a map to explore Angkor virtually and to learn about the important role of water and water systems (canals, reservoirs, and tanks) in the Khmer empire. The three-part activity concludes with a discussion on the climate vulnerability of Angkor and climate variation as one of the causes of the downfall of the Khmer empire.

Step 3 : Further exploration using a hands-on activity (Go to the Activity)

Use the teaching module “Water & Climate” from Virtual Angkor to help your students explore the history of Angkor and the Khmer Empire in a hands-on, interactive manner and to learn about how climate-related factors may have played a crucial role in the decline of this empire.

First, navigate to Theme One (Living with Water) of this module: https://www.virtualangkor.com/water.

  1. Read the introductory paragraph.
  2. Ask students to play the video and to explore the 360 degree views to learn about the role of water in the Khmer people’s lives.
  3. Facilitate a discussion on Questions 1., 2., and 3. of this module.

Next, navigate to Theme Two (The Hydraulic City) of this module: https://www.virtualangkor.com/water-t2.

  1. Read the introductory paragraph.
  2. Ask students to play the video and to explore the 360 degree views to visualize the rice fields and irrigation system in Angkor.
  3. Ask students to study the map.
  4. Facilitate a discussion on Questions 1. and 4. to learn about the water and water features in Angkor, and the significance of water in the Khmer empire.

Then, navigate to Theme Three (Climate Vulnerability) of this module: https://www.virtualangkor.com/water-t3.

  1. Read the introductory paragraph.
  2. Navigate to the article “Climate as a contributing factor in the demise of Angkor, Cambodia” listed in this module (https://www.pnas.org/content/107/15/6748). Encourage students to read the section, “Climate and Societal Vulnerability at Angkor”.
  3. Facilitate a discussion on the water management system in Angkor, the barays, and the modifications to the water management infrastructure. Discuss the role of climate-related extreme events (droughts and floods) in the downfall of the Khmer empire.
