Here on BI most of the folks I know have a decent stash of supplies, water, etc. There is a routine when the tsunami warning hits, too: it varies but its pretty much top off your household supplies (are you sure you have enough TP?) and then fill all the cars. Costco and all the gas stations get pretty busy.
Not too many looking for handouts here. Those who aren't prepared to some degree are generally newcomers. For most it is only an emergency if they aren't prepared.
And, seriously, be careful knocking the FEMA folks. They really are here to help and the people who handle emergencies here in Region 9 are NOT AT ALL the same clowns who screwed up Katrina. Hawaii has the best Civil Defense crew in the world. Fact. And those are local - State and County - agencies. Comes from having plenty of practice. They WILL do their best to get things back up and running if they can. The government here may be screwy in the day to day but when the going gets tough they KNOW how to respond well.
We do need more farms. We didn't just trade farms for housing, we traded them for grocery stores. Hawaii used to EXPORT food - and I'm not talking about sugar and pineapple. Hawaii fed the San Francisco gold rush. Redwood lumber came over on the ships and cattle went back. Shippers raked it in both ways. But as the population grew here and the West Coast developed its own food production, the shippers needed something else to make money on so they became the grocers. They systematically destroyed the fish ponds, taro lo'i and potato fields and replaced them with sugar and pineapple. Voila: the very model of western imperialism. Destroy the local food source, use the hungry populace as cheap labor and soak all that money back by selling them everything they need.
This is still the case. You can't simply have more farms without seriously upsetting someone's apple cart. From an emergency standpoint more local, diversified food production is a no brainer. From the county and State standpoint we don't need food, we need commercial scale agriculture, usually monocropping. That's taxable at a significant enough level to make a difference.
The Big Island alone could feed the rest of the state IF we don't assume meat as the primary source of protein. If we do, then the BI, Maui and Kaui could probably handle the protein needs (and I do mean needs) and we'd have plenty of additional foods to export.
But none of that holds a candle, tax-wise, to development and high real estate values. From the State viewpoint more farms is a revenue loss. Unless you're talking GMO farms. That's commercial scale and provides a fair income for the State. Monsanto is also the biggest funder for UH and has been for decades. Money talks. That's the only language the budget folks understand.
But that is also why our Civil Defense is so good. It is a huge priority to get things back to normal FAST so that the tourists can comfortably spend their money here so Civil Defense is fairly well funded and equipped.
