Jaroslav Pavlíček's handbook contains knowledge many times proven in practice, collected in more than fifty years. It should serve groups that prepare expeditions to the problematic places of the country and choose the harsh conditions voluntarily, as well as the castaways who get into the harsh nature inadvertently, against their will.

A person in harsh nature brings essential information whose knowledge can decide on survival. The book has been translated into English, German and Chinese and recorded over 100,000 copies sold.
