How should 3rd world local communities and villages be ready to react after a disaster happens when there is no local or international aid to support?

DISASTER RECOVERY PLANS ARE IMPORTANT IN ALL WORKS OF LIFE . THIS DOES NOT EXCLUDE THIRD WORLD COUNTRIES . IT IS IMPORTANT FOR THIRD WORLD COUNTRIES TO INVEST IN DISASTER RECOVERY PLANS .

In case of lacking local and international aid, you to to adopt the strategy adopted by the china duringth century when their whole city was destructed by the earth quake and they simple recovery the affect community by promoting the local community of china to support one affect person by each of volunteer family, and each person of the county has to bring one break,1 kg of cement and1 kg sand, they collect that from whole country, the cleanness of derbies of affect city did by their own people. With in few months they build the whole city better than the older one , even by not spending a single pinny even not lacking to international aid .

Just the big thing is when you have authority and you have skills to use it in right direction then nothing is impossible 

First of all they should have unity and good governance. A leader who knows how to delegate its staff and anticipates the needs of the community in every possible situation. 

The only way to be sure a community will respons/ react safely in the event of a disaster is by preparing them for disasters expected at their communities through public education and then by practice, practice & more practice.

I am a Filipino and I experienced living thriving in a disaster prone area of the Philippines: Cagayan Valley. It is the Northeastern part of Luzon that is adjacent to Pacific Ocean and Philippine sea, the areas where most typhoons are rooting from. When we were struck by super typhoon  "Lawin" or "Haima"last October 21, 2016, all we did was just to maximize all that we have in our own locality. We were informed earlier about the disaster that comes. Actually, three days prior to arrival of the typhoon, all classes, and offices were mandated to close except for the Disaster Response team, Rescue team, Bureau of Fire Protection, Philippine National Police, Philippine Red Cross, and Hospitals.  Immediately after the typhoon the community people just helped each other build the community but they started restructuring their own houses. Basic commodities like water, food, emergency light, and medications were prepared ahead of time. While fixing our own shelter, since  almost 3 weeks that there were no offices we just waited for an emergency response form the national government and adjacent local government units. I have been living for 28 years in a typhoon-adapted community and I can say that typhoon Haima so far is the strongest but we survived it.
