Security

Overview

This will be divided into regional and personal security. Both however, will be affected by this;

State security

There have been many concerns posted online regarding the militarization of police forces. I believe the reasons for this are two-fold, the first is practical, the second strategic.

On a practical level, the militarization of the police is the reflection of the deeper issue with guns. If I was tasked to raid a crack house, I honestly think I would want a well armed SWAT team.

The social impacts of climate change are going to get ugly for the police. It's a dichotomy. Arm them and worry about a military state, unArm them and worry about your neighbor.
Have a look at all the officers killed by gunfire on the following page

It's true there may not be a definite statistical trend, but I sure as hell wouldn't want to be a statistic.

The larger issue is the more important, with a less well defined moral boundary. With climate change is going to come migration, and poverty. The government is well aware of it. There will be migrations of people. I am going to make huge generalizations here but as specified elsewhere, they will be uneducated, poor, potentially sick and desperate. There will be a lack of food and affordable places to live. Added to that volatile mix, it will be hot. Heat and violence are linked, and again.
It would seem to the general public that governments are completely ignorant of climate change. I don't believe it. People are justified in saying that many governments are doing everything in their power to accelerate climate change, they may be right. But I think the governments are actually fully aware of what is coming. They are ignoring the climate because they see no other way to grow the economy. Just as the issue about WMDs in Iraq was really about oil, denial at higher echelons is about growth. Their thoughts may well be if we can continue economic growth we have a better chance to survive what is around the corner. They know exactly what we know, why wouldn't they? They're the ones silencing the scientists. Why would you silence them if you were not afraid of what they had to say?

A bankrupt country facing a baby boomer tidal wave, will not make the adjustments that will be required. 

Imagine a world with 9 billion, that can sustain 3 billion. A country with high unemployment and with high immigration, is a recipe for social conflict and extremism. Let's take an example. During the recent extreme heat in India, due to corruption some local power stations in India diverted power to more affluent neighborhoods. The result, the mobs burnt some of the power stations down. Understandable, and it seems like shooting yourself in the foot. It is however, the natural reaction of the oppressed. 

It may well be that certain levels of collateral damage have already been accepted. That is what I believe the police are being prepared for. Societal cohesion at any cost. What price are we willing to pay for the security of our communities?

Is all this speculation? Seems not.

I would conclude that this is beyond our control and that there is no point in fighting it. If the correct preparations are made, no extreme acts will be required.

Powerful men are well advised not to use violence,
For violence has a habit of returning;
...
For even the strongest force will weaken with time,
And then its violence will return, and kill it.

Violence, even well intentioned,
always rebounds upon oneself.
When things get hard, fighting them will only cause greater distress to a failing society, it would create a situation where evil finds more opportunity.
Thorns and weeds grow wherever an army goes,
And lean years follow a great war.

What to do? Again, be prepared, so that you don't have to be part of the mob.

For the rest, I am going to focus on personal security. 

Personal security

It doesn't matter what sort of oasis you setup, you are going to have to protect it. The easiest way to do that is by having the right location to begin with.

Once these considerations have been taken into account, then the choice is to stay or go. It comes down to this. If you stay in an area that is unsustainable for much of the population, then your considerations are going to be about initial defense and then implementing adaptions that will sustain you. If you choose to go to an area that environmentally can sustain many people then you would have to go and fortify because the threats will be constant.

Personally, I will choose adaptation because mankind has a propensity for warfare. Mentally weak people will not stay in an area with a hostile environmental conditions. They will be unprepared, and so, forced to migrate away. That means initially, strong defense will be required. However, there will be many targets, so any strong defense will not be met with a protracted offense. Psychologically, they will have accepted climate change and realized that they cannot stay where they are. In that sense, fighting against an entrenched foe has a limited payoff.

It is inevitable that gangs will increase. Gangs offer security. Research has shown the groups lack the morals of the individual. It is not a good mix. 
You have to wonder sometimes how much humanity really has progressed beyond base drives.


Do not stay in a densely populated area, it is unsustainable.
Know your neighbors.
Have an alarm.
Get a dog
Get a gravel driveway.
Avoid going out on your own.
Research non-lethal defensive weapons.
Get your kids into martial arts
Grow brambles as a hedge.
If you don't have a high front fence then don't grow anything that blocks a view of your windows from the road. 
That, or grow a high thorny hedge around your entire block. The problem then is the driveway gate which will have to be tall and difficult to climb.

Keep a low profile, drive a bomb of a car, wear daggy clothes.

Underground facilities

The benefits are many. It was, and still is the best form of defence against attack, the elements and vermin.
The ultimate security is provided in underground facilities. With Derinkuyu being the prime example of how effective it can be even at the level of a community. This does not equate to being a caveman. This is from Coober Pedy




Tunneling has and is an effective measure against a much superior force as was demonstrated by the Viet Cong in the Cu Chi Tunnels.
