what could be the best option to utilize the underutilized and abandoned land?
There are probably a lot of options for using this kind of land. Could you tell us where you’re writing from? That might help people give more appropriate answers!
In my point of view that would be impossible to me for giving you an acceptable answer without knowing.
1- What do you want to do with this land ?
2-Why it is underutilized and abandanded?
3- Describing the soil ( color,location,inclination,vegetation etc)
4- Even give photos if possible.
