The demand for fishing is not included in the graph

[redekok]

In our area analysis on ETDataset, we query the EB demand for fishing in the agriculture analysis for some further analysis. However, this demand isn't queried in the agriculture (final demand) nodes in the graph. These only query the different agriculture/forestry EB demands. As discussed with @AlexanderWirtz and @michieldenhaan, we should include the demand for fishing in the transport sector (inland shipping). We should also make sure this is consistent with the analyses on ETDataset.

@mabijkerk and I had a look at the fishing flow on the European energy balance, and found that moving fishing from agriculture to inland shipping provides some challenges.

The main issue arises because of additional products used in fishing, for example electricity and geothermal energy. These products do not correspond to the energy carriers used in the current inland shipping sector in the energy graph. @mabijkerk pointed out that inland shipping is based on technologies, and that additional energy carriers can therefore not just be added to the ETM sector.

One solution could be to allocate the energy corresponding to the existing inland shipping energy carriers to inland shipping, and leave the other energy balance products in the agricultural sector. Another solution is to leave the total fishing flow in the agricultural sector.

@mabijkerk also identified another discrepancy. Because inland shipping is based on tkm, many of the fishing activities would not fit the inland shipping category.

@AlexanderWirtz @michieldenhaan; @mabijkerk and I would like to hear your thoughts on this.

[mabijkerk]

Thanks for the explanation @lottevanvlimmeren! About the tkm, I mainly wonder whether it's valid to say that energy use for fishing contributes to the transport of goods. I would think that activity of fishing, and therefore the energy use associated with it, should not be considered as transport of goods.

@marliekeverweij is this something we might be able to address in the expected EU dataset improvements?

[mabijkerk]

Problem Currently, the ETDataset datasets (nl2019) does not include fishing demand in the energy graph at all. See for example the transport_final_demand_electricity node:

~ demand =
    EB("transport", electricity) -
    EB("non-specified (transport)", electricity) -
    EB("pipeline transport", electricity)

The ETLocal EU country datasets however do include fishing demand under transport - domestic navigation (inland shipping). This is an inconsistency that should be addressed at some point. See for example the interface elements that maps ETLocal inland shipping demand:

- key: input_transport_ship_electricity_demand
          unit: 'TJ'
          entso: |
            EB("Final consumption - transport sector - domestic navigation - energy use", "Electricity") +
            EB("Final consumption - other sectors - fishing - energy use", "Electricity")

Potential solution According to Eurostat, fishing has the NACE (economic activity sector) code Rev. 2 Division 03: A3 - Fishing and aquaculture. This means that it is part of A - Agriculture, forestry and fishing. Simply put, according to Eurostat fishing is part of agriculture.

A potential solution would therefore be to add fishing as a sub sector to the agriculture sector. We might also check what approach other statistical agencies such as CBS or Klimaatmonitor use.

@AlexanderWirtz, shortly summarized:

• Final demand for fishing (Final consumption - other sectors - fishing - energy use) does not see to be included for ETDataset country datasets, but is included for ETLocal EU country datasets. For regional datasets I'm not sure
• My proposal is to allocate fishing to the agriculture sector, since agriculture represent NACE sector A, which consists of "Agriculture, forestry and fishing"

Do you agree?

[AlexanderWirtz]

@mabijkerk yes, that is correct. To be precise, when you say:

My proposal is to allocate fishing to the agriculture sector

you mean doing so in the ETDataset data flow, right? Either way, that is where it belongs.
