“Desert Survival” by Charles A. Lehman was one of the first books I thought of including when I began the “Survival Library” series of blog posts.
Not surprisingly, this book concentrates on survival in a desert environment!
There is, however, plenty of sound advice relevant to other environments, so you can only be commended if you are flicking through a copy sitting in a hut near one of the poles.

Two Priorities
Lehman gives the survivor two priorities:
The first is “looking after your body”.
Secondary to this is “getting rescued”.
The primary threats to your body in the desert are identified as hyperthermia, dehydration and hypothermia. Some of these are, of course, concerns in other environments.
Chapters on shelter, clothing, fire-lighting and medical emergencies, among others, all relate to looking after your body.
Advice on getting rescued includes a useful account of how a search and rescue (SAR) operation will conduct a search, and steps a survivor may take to help (or unintentionally hinder) an effort.
This is information not included in most survival manuals, so the book is worth reading for this section alone.
Survival Kits
Another very good section is the advice given on putting together your own survival kit.
His advice is similar to what I have been repeating on this blog for decades: Avoid gimmicks and gizmos, don’t put all your eggs in the same basket, and have some vital items on your person, not in a pack or jacket you might put down “just for a moment”.
The survival kit/outfit suggestions are more practical than many I have encountered. I would recommend the addition of some space blankets and a compass to the personal items. To the suggested vehicle kit I would also include some duct tape, since it is more effective for certain tasks than electrical tape.
To my mind, the section on shelter was a little brief, and I feel some mention of double canopy shelters would have been appropriate for a book about surviving deserts.
Like many authors, he recommends the use of woollen clothing, with little consideration given to just how high a price tag often comes with such an outfit these days. Some discussion of alternatives might have been given.
While I no longer have enough hair to really justify carrying a comb, apparently I can use one to remove cholla cactus!
Pilot Outfitting
Advice given for pilots includes:

“Diversity of environmental problems complicates the "What to Wear" problem for pilots and passengers in light aircraft. Fortunately, there are some ways to cope with it. One of the easiest answers is to wear a flying suit like military pilots do. The utter utility of multi-pocketed coveralls is hard to beat.
With a good quality flight suit as an outer layer, even a business suit becomes an acceptable survival garment for moderate temperatures. If you fly over really cold areas, carry a set of the quilted type of insulated underwear. They weigh very little and offer super protection.
In really hot weather the suit will protect you from the sun and scorching rocks or sand. Try to find one that has side zippers, as well as the one in front. They allow you to ventilate the suit better.
With a flying suit, insulated underwear, and a good hat, you are nearly prepared for a survival situation, but you will need boots. This is the only clothing item that's really a weight problem. If pounds are critical in your aircraft, I would recommend wearing boots instead of shoes when you fly. That way the additional weight is insignificant. There are sturdy boots available that are dressy enough to wear with a business suit.”
To echo another desert survival manual (Air Ministry Pamphlet 225): “always fly in the boots in which you intend walking home.”
The medical section is clear and simple, grouping likely problems under eleven headings, distinguished by means of treatment. This would be a good section to photocopy and carry with a first aid kit.
A minor criticism is that the illustration of pressure points (aka “digital pressure”) seems to omit many of the points on the limbs. Add a copy of a better diagram, such as in “SAS Survival Handbook” or FM 4-25.11/FM 21-11.
The chapter on playing “What If?” nicely rounds off the book.
This book would not be my sole read for survival, even if my particular priority was desert survival. It is never wise to trust a single source on any subject.
The book is very much orientated towards North America, so some additional background reading would be advised if heading to sandy places elsewhere in the world.
I would recommend adding this book to your survival library, since it nicely supplements the titles suggested in Chapter One.
Many survival manuals can be “much of a muchness”, which makes them rather a chore to review, if nothing else.
Desert Survival is highly readable, and the different approach of this manual is refreshing, which probably helps you retain more of the information.
A very nice feature of this book is that it crams in a lot of useful information into just 81 pages. That is very welcome, given so many manuals run to hundreds of pages and can be heavy going.
