so, let’s go way back to the Code_of_Hammurabi, which dates from about 1700BCE, and had this to say about what to do in case of natural disasters:
If a man owe a debt and Adad inundate his field and carry away the produce, or, through lack of water, grain have not grown in the field, in that year he shall not make any return of grain to his creditor, he shall alter his contract-tablet and he shall not pay the interest for that year.
simple law for simple people perhaps, but effective in reducing the burden faced by those trying to produce corn on about 40 million acres affected by the drought.
no ‘off the shelf’ economic tools required. just a couple of lines of legislation.
don’t run away - campaign your representative for effective laws that help people in times of difficulty
