Value type “environmental issue (Q2144359), environmental process (Q112622562)”: This property should use items as value that contain property “subclass of (P279)”. On these, the value for subclass of (P279) should be an item that uses subclass of (P279) with value environmental issue (Q2144359), environmental process (Q112622562) (or a subclass thereof).

Constraints

I'm unsure whether {{Constraint:Type|class=Q2144359|relation=instance}} or {{Constraint:Value type|class=Q2144359|relation=instance}} is the right constraint to indicate that the values of this property should be instances of a subclass of environmental issue (Q2144359).

I'm also unsure how to encode the constraint. This property should be used with one of point in time (P585) or start time (P580) (which can be combined with end time (P582). /André Costa (WMSE) (talk) 10:31, 17 February 2017 (UTC)

Example qualifer use (from proposal)

To illustrate a more complex example: Acidified lake which was cleaned up in 2016 only to be found to suffer from eutrophication in 2017.

• ⟨ Orlången (Q3424558)    ⟩ significant environmental impact (P3643) ⟨ acidification (Q10501532)    ⟩
  point in time (P585) ⟨ 2014 ⟩
  end time (P582) ⟨ 2015 ⟩
• ⟨ Orlången (Q3424558)    ⟩ significant environmental impact (P3643) ⟨ no value Help ⟩
  point in time (P585) ⟨ 2016 ⟩
• ⟨ Orlången (Q3424558)    ⟩ significant environmental impact (P3643) ⟨ eutrophication (Q156698)    ⟩
  point in time (P585) ⟨ 2017 ⟩

The middle case is I useful to illustrate years when the water body was reported as not suffering from any issues (as opposed to there not being any data for that year)./André Costa (WMSE) (talk) 07:32, 19 June 2017 (UTC)

Question regarding restoration

I'm working on adding knowledge from restoration ecology to Wikidata. It would be very useful to have a property that describes the type of degradation that a practitioner is trying to restore from. For instance, we have many studies on restoring oil sands impacts (particularly well drilling and seismic lines). It would be great to be able to tag these studies.

It looks like this property is most suited for a particular place impacted by a stressor. Is there a modification or change that could make this a bit more general and useful for studies of stressors, like we see in restoration? Or should I propose a new property?
