Extraction / harvesting

Goal: find as much material flow data as you can on the extraction / harvesting of the 11 construction and/or 12 biomass materials and add those to the sublayers of 3.1. Extraction/Harvesting with the usual upload and tagging procedure.

Outline of the video

  • Extraction from nature
  • Includes agriculture, fisheries, forestry and mining
  • You did previous work to find out if there are mines or farms, now you can match the data on details on how much and what exactly is extracted.
  • M2:06, what to look for
    • Mining data
    • Agricultural production (by crop)
      • Yields x area; area farmed could be stable, but yields could be different from year to year
    • Fish landings (by species);
      • Also include fish farm, kelp, seaweed output
    • Wood production
  • M5:36, examples
    • Mines in Cape Town
    • Farmed land in Cape Town (CapeFarmMapper)
    • Fish landings in Cape Town; data from ministry; Paul put in a request for the data;
  • M9:40, sources
    • Relevant authorities (local or national)
    • Industry/government reports
    • Industry associations
    • Experts
Soil

Outline of the video

  • Soil is quite varied. It is the top layer that supports life.
  • Hard rock is not part of soil anymore.
  • Composition could be of clay and sand.
  • Why is soil relevant? Nature, construction, water runoff
  • What to look for: general understanding, soil profile, maps, descriptions and reports on soil.
  • Examples from M7:07.
  • Sources that can be used

Construction

Goal: Try to find data, namely numbers representing weight, on the 11 construction materials (and waste) flows from extraction. Yes, waste can also occur at these early stages, as you know!

Approach:

  1. Go to your worksheet and check for each of the 11 materials, if the extraction related economic activity takes place in your city. For some of the materials, “extraction” does not make sense directly, for example, you cannot extract glass. Therefore, we are providing an overview of the materials that should be checked instead. In the case of glass, it would be sand and limestone, for example. To do this check, consider if the economic activity plays a role in your city.

    • For example, for bricks, “extraction of clay” may or may not exist in your city. (This could be an easy check, if you have found that there are employees active or GDP/GVA is created per 4-digit NACE code.)
    • If there is no such economic activity, then there is also no flow data for this activity. Be sure to mark in your worksheet at the correct material when an economic activity does NOT exist. → Continue to check for the next material.
    • If there is this economic activity in your city, then move on to point 2.

  2. Try to determine the quantities of materials extracted (= data in numbers (weight)) by finding a document/dataset that contains this information. Be sure to note over which time frame it is extracted (per month, annually etc.)

  3. Upload this information and be sure to tag it correctly with the 3 fields for tagging: (1) physical location, (2) materials, (3) tags. (The sector field can be left out.)

    • For example, when you add a dataset on the extraction of clay in your city in Layer 3.1. Extraction/Harvesting, use the following tags: (1) your city, which is added automatically, (2) “EMP8.4 Bricks” (the material tag) and “EMP8 - Buildings and construction materials” (the sector tag), and (3) 3.1. Extraction/Harvesting, which is added automatically. In the uploader notes, you can add that this is about the respective NACE code, so in this case “08.12 - Operation of gravel and sand pits; mining of clays and kaolin”.

Biomass

Goal: Try to find data, namely numbers representing weight, on the 12 biomass materials (and waste) flows from extraction. Yes, waste can also occur at these early stages, as you know!

Approach:

  1. Go to your worksheet and check for each of the 12 materials, if the extraction related economic activity takes place in your city. For some of the materials, it is difficult to know what is included in them, therefore your colleagues have added an overview in the flow diagram description. You can also find an overview of the materials that should be checked. To do this check, consider if the economic activity plays a role in your city.

    • For example, for fish, “fishing of fish” may or may not exist in your city. (This could be an easy check, if you have found that there are employees active or GDP/GVA is created per 4-digit NACE code.)
    • If there is no such economic activity, then there is also no flow data for this activity. Be sure to mark in your worksheet at the correct material when an economic activity does NOT exist. → Continue to check for the next material.
    • If there is this economic activity in your city, then move on to point 2.

  2. Try to determine the quantities of materials extracted (= data in numbers (weight)) by finding a document/dataset that contains this information. Be sure to note over which time frame it is extracted (per month, annually etc.)

  3. Upload this information and be sure to tag it correctly with the 3 fields for tagging: (1) physical location, (2) materials, (3) tags. (The sector field can be left out.)

    • For example, when you add a dataset on the fishing of fish in your city in Layer 3.1. Extraction/Harvesting, use the following tags: (1) your city, which is added automatically, (2) “EMP1.4.1 Wild fish catch” (the material tag) and “EMP1 - Biomass” (the sector tag), and (3) 3.1. Extraction/Harvesting, which is added automatically. In the uploader notes, you can add that this is about the respective NACE code, so in this case e.g. “03.11 - Marine fishing”.
