Analysing Environmental Problems Flashcards
To effectively address global environmental challenges, what do we need to do?
- Systematically identify and analyse the sources that lead to environmental pressures as well as the nature of flow-on effects in nature, and back upon humans.
What two systems are used to identify any problems and their solutions?
- The DPSIR framework
- The IPAT equation
Why do we use the DPSIR and IPAT models?
- To analyse and help guide sustainable production and consumption
What is the DPSIR framework?
- Systems analysis of environmental problems
- A cause-effect framework that describes the interactions between society and nature
- Great for systematic analysis and planning to help fix environmental problems
What does DPSIR stand for?
- D = Driving forces
- P = Pressure
- S = Changes in the environment
- I = Impact of changes in environment on humans
- R = The responses of humans to there impacts
What are the Driving forces in the DPSIR model?
- Are the human activities, processes and patterns that are the sources of environmental resource and waste flows and their impacts
What are the Pressures in the DPSIR model?
- The material and energy flows (releases and intakes) between human (economic) activity and the natural environment
What are the State trends in the DPSIR model?
- Trends or changes in biophysical conditions on Earth; the quality and quantity of natural resources
What are the Impacts in the DPSIR model?
- The ultimate effects (cost and benefits) of environmental state (S) change on people
What are the Responses in the DPSIR model?
- Intentional human action and strategies to deal with impacts or changes in pressures and states
Why is R the most important part of the DPSIR model?
- Policy is focused on the “R”
- Human actions to deal with the environmental challenges are “Response”
- R is about how can our “Response” change the “Driving forces” (preventive)
What is the relationship between the DPSIR model and the IPANT model?
- PANT (from IPANT) fits into the DRIVING FORCES of the DPSIR framework
- The I from IPANT is the same as P in the DPSIR
What does IPANT stand for?
- I = Pressures
- P = Population
- A = Affluence (overall consumption or output per person)
- N = Nature of output or consumption - composition
- T = Technology - based environment - intensity of each form of output or comsumption

Why is IPAT important?
- The IPAT equation is one of the best approaches to deeply understand the real driving forces behind any environmental issue
- Its extensions, like IPANT break down the I = PAT
- It separates P out, and then splits A.T into different types of economic activity (output and consumption), that is, different “layers”
