TPA ke under kya hai 'Change of Land Use'?

Main sochta hoon ki TPA ke under 'Change of User' ke baare mein padha hai, lekin 'Change of Land Use' ka kya arth hai? Kya yeh TPA ke under ek alag cheez hai? Maine abhi tak koi textbook ya case niye par nahi diya jo iske baare mein batayega. Koi bhi help karega? Maine socha hai ki yeh 'change of user' se alag cheez hai, lekin abhi tak main samajh nahi paya ki kya hai isse faayda. Kya yeh Property Law ya TPA se related hai? Kafi confusion hua hai mujhe.
