[(E)]

More thoughts that will hopefully turn into a worked example soon

AtE gold rushes
- Power the remnants of a power network could be a big bonus.
- Fuel, possibly even bio-fuel from the algae?
- Genetics, healthy genetics for crops and livestock
- Information, knowledge is power, especially if pre-End everyone relied on Cloud data storage
- Glass bricks, specific to the end below

Assumptions
- big storms
- warm seas
- Cold dry continents
- ecosystem messed up
- increased erosion improves soil nutrients in some locations.
- if pessimistic then the range of crops available would only be tropical and sub tropical

What isn't present
- Crops that take a long time to grow. Possible exceptions include sugar cane.
- Citrus trees, bees are required.
- If there are no locations with stable temperatures potatoes will be less common or possibly absent. This is more likely in hotter conditions. The potato species that do exist are older hardier varieties. The taewa (maori) potato varieties have all been historically farmed on pacific islands so in theory can handle higher temperatures.
- fruit trees in general are going to be scarce, generally weaker than other trees the harsher weather will damage them or their fruit. The change in weather patterns will affect trees more than annual plants.

Systems
Underground
The risk of Megastorms will seem to suggest that every community will have a secondary food supply if at all possible. Increased rainfall makes hydroelectric a likely if unreliable power source for any crops grown under artificial lights.

Glass bricked greenhouses.
Protection from the harsh weather as well as the radioactive particles stirred up by the storms will be an issue. Greenhouses will have to become tougher to cope. Glass bricks may be a solution smelter from the abundant glass left from before the End (annealing will be required). These greenhouses are likely partially below ground with low curved roofs to minimize the wind profile.
The primary purpose of these greenhouses will be food security and protection of crop genetics.

Fast growing crops.
It is a reasonable assumption that the storm activity combined with glacial action would result in some flood plains having very fertile soil. These areas would be highly susceptible to storm damage so fast growing high energy crops will be desired.
- Fonio 45-60 days
- Some millets around 60 days
- Fast growing maize varieties 42-50 days, hot sunny conditions required though (which match hurricane season).
- some legumes 60 days
- summer squash 60 days
Taro which is somewhat flood resistant may also be planted or maintained as a feral crop.

Range of microclimates
One issue is going to be the huge range of microclimates that exist, a lower snow line away from the ocean and increased water temperatures will mean one valley's successful farm system may be the next valley's famine.

livestock
The range of climates and conditions make generalizations to do with livestock difficult. However faster growing and smaller animals have the highest chance of survival as farm animals. Having high stable temperatures at sea level will benefit parasites so yields will be down.
Pasture quality
This could go either way, less bees mean less non grass species (including many weeds) but more storms mean the nitrogen cycle will be supercharged.
Sheep
- dominant breeds might include "Gulf Coast" with high parasite resistance and "Romney" that can handle a wide range of conditions and have better than average parasite resistance.
- both these breeds produce "strong" wool which is better suited to blankets and carpets as opposed to clothes. Techniques exist for using wool in place of the plastic nylon. This is not limited to textile use either, one example is artificial hips.
Cattle
- Parasites could all but destroy cattle farming. Tropical parasites such as Theileria will find little resistance in non tropical breeds/genetics.
Goats
Browsing species such as goats may be viewed as a threat to the forest by some groups.

Bit of a waffle I'm afraid, I will write up a settlement soon.
