Welcome Nichole and family!
In perhaps a shameless plug, Columbia Basin
Permaculture has been working on just such an environment for the past six years.
For a basic synopsis of what we in dry/hot summer/cold winter/windy environs are up against, check out www.growritzville.com.
The initial condition is evapo-transpiration exceeds precipitation. This means that anything and everything we do to capture and preserve moisture (whether in storage ponds/tanks or in the soil) is essential. The goal is to "effectively" reverse the inequality such that we end up with an abundance of
water with which to live and grow our forests/gardens.
Mulch,
compost, obtaining just about any organic debris, windbreaks, shade techinques, hoop houses, earth sheltered greenhouses,
hugelkultur ... all contribute to rebalancing the initial inequality in our favor.
