Significant environmental impacts[edit]
Originally proposed at Wikidata:Property proposal/Natural science
| Description | The types of environmental issues determined to have a significant impact on the object. |

| Data type | Item |
| Template parameter | försurning/övergödning/... in w:sv:Template:Insjöfakta Sverige |
| Domain | any geological feature or only body of water (Q15324) (see discussion) |
| Example | Orlången (Q3424558) → eutrophication (Q156698) (with qualifier point in time (P585) →2010) |
| Source | pp.43-44 of WFD Reporting Guidance 2016 (pdf) and e.g. xml for all lakes in Finland (warning 13.1 MB |
| Planned use | This is part of the WFD to Wikidata project aimed at making use of the WFD reporting data in Wikidata. See also motivation. |
- Motivation
As part of EU Water quality reporting requirements any significant environmental impact types effecting a water body must be reported. Note that there are no absolute values (g/m³ or similar) to go with the official EU data. Each national (and possibly sub-national) environmental agency has guidelines to decide what levels are to be considered significant for each type of impact. Examples of impact types are eutrophication (Q156698), acidification (Q10501532), chemical pollution, litter (Q1780867), saline pollution, elevated temperatures etc. (~12 used in EU data)
This information (data from 2010) is already in use for lakes on sv.wp (see e.g. infobox in w:sv:Orlången) but new official data from 2016 is now available (for all EU countries). It is therefore an excellent opportunity to ensure Wikidata gets used now that this data has to be updated anyway.
Since I can imagine similar data being used for non-water bodies I have (initially) not limited this proposal to just environmental impact on water bodies. André Costa (WMSE) (talk) 17:04, 19 January 2017 (UTC)
- Discussion
@Innocent bystander, ChristianKl, Izno, TomT0m: Note that I previously touched on this in Wikidata:Project_chat/Archive/2016/10#How to model properties with yes/no values (it was however archived before I had time to reply). For that reason I've also pinging the users who participated in that discussion. Also per instruction 
WikiProject Taxonomy has more than 50 participants and couldn't be pinged. Please post on the WikiProject's talk page instead..
I'm happy to bikeshed the name to clarify it further or to either make the property limited to only body of water (Q15324) and/or to make it EU specific so that only a finite set of values are acceptable (if so that would be Annex 1b (p.307) mapped to Wikidata).
I would suggest that we require that all usage of the property comes with a point in time (P585) (or start time (P580)/end time (P582)) qualifier. It might also be an idea to require all of the values to be an instance of e.g. environmental issue (Q2144359). /André Costa (WMSE) (talk) 17:04, 19 January 2017 (UTC)
Question: How do you model that Orlången (Q3424558) does not have problems with eutrophication (Q156698) any longer? -- Innocent bystander (talk) 19:47, 19 January 2017 (UTC)
- My suggestion would be to add end time (P582) as a qualifier with the year when this was removed as an significant impact.
- To illustrate a more complex example (using P369 instead of the proposed property): Acidified lake which was cleaned up only to later suffer from eutrophication.
- ⟨ Orlången (Q3424558)
⟩ Sandbox-Item (P369) ⟨ acidification (Q10501532) ⟩
point in time (P585) ⟨ 2014 ⟩
end time (P582) ⟨ 2015 ⟩
- The middle case is I useful to illustrate years when the waterbody was reported as not suffering from any issues (as opposed to there not being any data for that year)./André Costa (WMSE) (talk) 11:51, 20 January 2017 (UTC)
- Sounds good! The presence of P582 as a qualifier is a good indicator! -- Innocent bystander (talk) 18:30, 27 January 2017 (UTC)
