Hey, I applied for Land Economy last year and received an offer.
With the Personal Statement the University gave the impression that because Land Economy is such a rare subject and offered at few other universities, they would understand if your statement isn't fully focused on LE.
But, in my PS I wrote about my interest in land and resource management issues and the economic development of China. I guess in the case of the latter they may be getting a little sick of it being mentioned in personal statements as I imagine many people will have done so recently. Perhaps, showing interest in something less obvious would be better.
Hopefully, that will help you. Most importantly though I would say to just be honest about why you find the course appealing and demonstrate it by mentioning your wider reading and experiences.
