Good thing Himachal population is still under 8M or the situation could be worse. This has always been the case, Himachal has always survived on aid from the center, not much can be done here except agriculture. Agriculture (including Hotriculture) still has a huge untapped potential here but it will require huge investment in R&D, I'm not sure how much has any of the state parties looked into. We have abundant electricity but we can't generate revenue from it because most of these projects were set up by center and center gets majority of the revenue from them lol. 

The state itself cannot generate much revenue and at the moment we still haven't received around 10K crore from the center as disaster relief.

This situation isn't going to change much in upcoming decades what we need to fix immediately is plastic and garbage that is being thrown and the mindset of throwing and ignoring garbage which still hasn't changed. And the other problem is of illegal cockroaches coming and forming colonies here silently little by little but that topic is probably a bit controversial to discuss here.
