I’ve shown parts of the Fairy Kingdom made barren by having too much magic thrown at them during the magical wars. I've also shown Eileen's attitude towards the realm's history here - this is one example where she does not go along with the official line. She is prepared to blame her own royal house and not just the Witch's family for what happened here. The fairy government tends to ignore the barren areas, they're considered an embarrassing blot, literally. I love characters who think for themselves, who query the official line and who land themselves right in it because of that uncompromising attitude. It makes for good stories.
How do your characters cope with adverse conditions, adversity in general?
If you needed to know the inner workings of your character's soul (or equivalent in your world), drop them right in it and see if they sink or swim. There can be fascinating stories in brave souls who crumple and quieter ones who show more backbone than expected. The contrast between bitter characters and those who make the most of what they have/are again can make for wonderfully tense scenes in fiction given the two types of character here are bound to clash. (If only because the bitter ones will think the others naive...).
Has the climate shaped your world in terms of geography, history, politics etc (in Britain’s case being an island has helped it in battle if only by getting us to be really good at seamanship)?
I haven't put all I know about my Fairy Kingdom in my work. I don't intend to either! But it is and continues to be helpful to me to be able to answer this question and others like it so I can get a feel for my world. I think I then write more convincingly about it. Knowing the answer helps clarify your thoughts and will help you work out what could be relevant to your story or what is likely to lead you off into a (non-helpful) tangent. In the Kingdom's case, the magical fighting of the past has damaged the environment. For Eileen it acts as a solemn warning.
What happens to those who damage, deliberately or otherwise, your world’s environment or does nobody care?
Fresdian (later Rose) is considered eccentric for caring so much about the realm's flora and fauna but her knowledge and dedication in finding out all she can about these things is respected. Fresdian herself would happily blast away anyone deliberately damaging the environment. It is the issue that winds her up.
Have you got a mental image of what your world is like?
I’ve based mine partly on Scotland (!), red rocky areas (Mars!) and part of it has rings around it (Saturn!!!). Magical attitudes to wildlife in my Fairy Kingdom are ambivalent - nobody’s that keen on dragons - but equally Eileen’s been keen to ensure harmless species aren’t wiped out because the sprites get hysterical.
