Kingdom XP for building structures?

[Paul Zagieboylo]

I noticed a couple of stray sentences on p. 536 under Freeholds: "When a new settlement joins a kingdom... the kingdom gains no XP for any improvements already built there. Any future improvements built there grant normal XP awards."

Does building improvements normally grant XP awards at all? Should it? Does this apply only to Structures, or also things like Farms or Work Sites? I can't find it anywhere, but it seems like it really ought to. Honestly it seems like most Kingdom activities are supposed to grant a small amount of XP, similar to unused Creative Solutions and Supernatural Solutions. But basically nothing does except Claiming Hexes.

Unrelated: what does Irrigation accomplish, really? It doesn't seem to improve Farmlands at all. I guess it allows you to fish? In your... irrigation canals?

For me, one major purpose for Irrigation is the building of canals in hexes that don't (yet) have a "River." This allows a kingdom's merchants to ply their trade along the waterways. This, in turn, allows for greater distances to be travelled in a given day, as there are no beasts of burden being worn out (presuming you are travelling downstream).

I'm sure there are several other reasons, many of which will prove to be just as good as the one I cited above.

Hope this helps.
