Very good points by all friends, some of my comments too :
1. Decentralization of major ministries and necessities ( airports, universities, hospitals, shopping malls etc ) so that people from all over Nepal don't have to come to Kathmandu for everything
2.Strict rules and regulations for making new buildings, roads, infrastructures etc
3.Giving enough loan to people to build their houses for 5 years with no interests, papers can be taken by loan providers unless loans are paid
4. Compulsory education on earthquake awareness and safety classes
There are more we can add, but will we be heard ???????
