Dealing with sudden fateful events - upanipAta pratIkAraH

उपनिपात - upanipAta means "a sudden and unexpected attack" of fate. cANakya states there are 8 such calamities.

1. Fire accidents
2. Floods
3. Contagious Diseases (that spread quickly among animals and humans)
4. Drought
5. Rodents
6. Wild animal attacks
7. Venomous snakes etc.
8. rAkshasas (those who find pleasure in troubling others and seeing them in pain - in modern days I can translate it as "terrorists")

A king should equip the territory to deal with any sudden attacks from any of the above categories of natural or man made calamities. People living in the territory should be protected even from the acts of god (or nature!)

All precautions should be taken to avoid fire accidents especially in the Summer period. 
King should have sufficient supplies of seeds in the event of drought. 

People who have required knowledge to predict, prevent and protect from these things should be living in the kingdom and equip the territory to tackle when any unforeseen events occur. atharvaNa vEda has the required formulae (methods and materials to deal with calamities) to handle most of the diseases, poisons etc, The specialists on these subjects should be revered by King and kept in the territory.

This is the subject discussed in the third chapter of kaNTaka Sodhanam.
