I live in a warm climate (Australia) where summers are hot (humid in early summer and dry in late summer), autumn and spring are warmish and wet, and winter is rainy and mild with no snow and rarely a frost. It doesn't get below freezing.
I'm just wondering if it would be possible/worthwhile to build a root cellar here? I would mainly use it to store autumn harvests like potato, pumpkin and late fruits (like apples and pears that don't store well in refrigeration) through the winter. I know apples and potatoes don't store well together, but before I worry about things like that, I really want to find out if the cellar idea can be done successfully here, or if I would be better served just forgetting about this idea and spending my time trying to sort out a solar dehydrator instead.
I have made little root cellars in the desert just in deep sand and shade. Not perfect but helps a ton to keep stuff cool.
lots of cellars have a vent to the outside and that helps with the temp. The vent is normally opened cooler parts of the year. Its harder to do when its warm all day but opening it at night when its cool can work. Burring in dirt for helping with its cool temps and for its insulation values. That and venting at the right times can make it work great. Otherwise If you use citywater. You can make a heat exchanger in your cellar to cool it when you run the water. Other wise solar dehydrator are great.
Hope that helps a bit let me know if you need more help.

Switching from electric heat to a rocket mass heater reduces your carbon footprint as much as parking 7 cars
