On the geography of deserts

What is a desert? What is a desert to a geomorphologist, a geoclimatologist, a biogeographer, a geoanthropologist, a cartographer or a geopolitologist? Geography, as a discipline that is as much concerned with terrestrial morphology and climates as it is with ecosystems and human societies, shed light on the various meanings of the term 'desert' in different fields of language and knowledge, providing insights into the significance of deserts for our contemporary societies. The ambition of this reflection is to unravel the complexities of deserts and help to grasp what deserts are and what they 'do' by encouraging geographers to merge bioclimatic analyses and geo-historical understandings, establishing the geographical discipline as the quintessential science of deserts.
