We know technology is expanding each day. Another interesting story from Australia starts off with a discussion about bringing broadband to the farm (and by extension other rural areas). It is pretty well known through marketing about precision agriculture, but there are growing technologies for other aspects of farming, from gate status (open/closed) to ear tags on livestock to show their current and past locations.
In the disaster recovery realm this technology can help assess damage after the fact (building and fence damage, livestock inventory) but can also work into disaster preparatory to get a pre-disaster baseline.
Some of these systems can be kept inside local networks, others need external internet access (e.g. depending on of solutions are local or on the cloud on remote servers).
This is a way to use GIS to keep track of assets at all times, and of course current weather data can be factored in (see my past post on showing the limitations of the weather radar network in Australia).
In Australia, some farmers may be able to use point to point WiFi networks, others are limited to slow and limited satellite options, the same holds true in the United States, some farms are close together in some states and further apart in other parts of the country, mostly in the western United States in the plains and mountains.
