Course Name : Environmental Science and Disaster Management

Code(Credit) : ASES3101(2-1-0)

Course Objectives

Disciplinary knowledge: Enable students to develop a comprehensive understanding of various facets of life forms, ecological processes and how humans have impacted them during the Anthropocene era.
Critical thinking: Capability to identify relevant environmental issues, analyse the various underlying causes, evaluate the practices and policies, and develop framework to make informed decisions.
Moral and ethical awareness/reasoning: Develop empathy for various life forms and appreciate the various ecological linkages within the web of life.

Learning Outcomes

Upon completion of this course, students will acquire knowledge about
• Understand the natural environment and its relationships with human activities.
• Characterize and analyze human impacts on the environment.
• Integrate facts, concepts, and methods from multiple disciplines and apply to environmental problems.
• Capacity to integrate knowledge and to analyse, evaluate and manage the different public health aspects of disaster events at a local and global levels.
• Capacity to obtain, analyse, and communicate information on risks, relief needs and lessons learned from earlier disasters in order to formulate strategies for mitigation in future scenarios.
