Principles for Ecologically Sustainable Management

Describe the roles of law, policy and stakeholders in environmental management, and explain how evidence-based decisions about contemporary issues are made.
2Q&A pairs
Describe environmental monitoring methods and fieldwork techniques, and explain how reliable, valid data is collected, analysed and used in environmental decision-making.
1Q&A pairs
