Imports and Exports flows (Module 8) - Online course Sector-Wide Circularity Assessment
The slides for this presentation can be found here.
Note: In the video, there is a reference made to electricity and water, but this is NOT applicable to CityLoops.
And here is an explanation on the National Statistics of Transport (NST).
Outline of the video
- Key part in our work
- Relates to all materials and products that are brought from outside of the city to the city.
- Fundamental work, because a vast amount of materials are imported and exported
- What are they, where do they come from, how do they move
- How does it happen: something crosses the city boundaries. We can consider how it crosses that. For example, by land with trucks or rail, by water with ships, by air with planes.
- Freight by train is more likely to be bulk materials (grain, coal).
- More hidden: transport by pipeline. (Water, gas)
- M5:33 overview
- Highly relevant to all flows
- Urban boundaries highly porous --> difficult to get numbers
- Freight statistics are key
- Transport-mode (TM) based vs. commodity-based (CB) approach
- TM: quantify everything that goes by rail or by pipeline; tracks it by activity
- CB: track all petroleum and look at various modes.
- Practical to take one approach and then add things up.
- Choice of approach is dependent on the data that is out there.
- There is also imports and exports of energy
- M9:37, examples
- South African ports
- M11:17, sources
- Statistical agencies
- Freight data agencies
- Relevant governing bodies
- Keywords: freight statistics, imports and exports + city name
