The survival of the mudbrick monuments of Merv against all the odds is little short of a miracle. Mudbrick and rammed earth are not building materials famed for their longevity, rather for their economy. However, some buildings of the Merv oasis in the Karakum desert in Turkmenistan have survived for more than seven centuries and some, unbelievably, for a millennium. Mud was the building material of choice, wonderfully flexible and a superb insulator, ideal for the extremes of the Central Asian climate, and one used by the architects of Merv with ingenuity and virtuosity to construct a wide variety of vaults and domes. The survivng monuments include palatial residences, small houses, summer pavilions and watch towers, as well as the earliest examples of tall conical icehouses. Perhaps the most remarkable are the extraordinary corrugated buildings, which, like the icehouses, dominate the flat landscape of the oasis. These are a distinctly Central Asian type of building with a surprising dearth of parallels elsewhere. Merv's key position during the eighth and ninth centuries may suggest that these remarkable buildings originated in the oasis, and they continued to be built through the Seljuk period. They present a unique record of an otherwise lost architechtural heritage and are of such importance that they form a major part of Merv's application to UNESCO for World Heritage Status. Merv was, of course, one of the great cosmopolitan capitals of the day, a centre of learning, industry and of long-distance trade: it was strategically located on the Great Silk Road'.

This book contains articles on historic cities of the Islamic world, ranging from West Africa to Malaysia, which over the centuries have been centres of culture and learning and of economic and commercial life, and which have contributed much to the consolidation of Islam as a faith and as a social and political institution. The articles have been taken from the second edition of the Encyclopaedia of Islam, completed in 2004, but in many cases expanded and rewritten. All have been updated to include fresh historical information, with note of contemporary social developments and population statistics. The book thus delineates the urban background of Islam has it has evolved up to the present day, highlighting the role of such great cities as Cairo, Istanbul, Baghdad and Delhi in Islamic history, and also brings them together in a rich panorama illustrating one of mankind's greatest achievements, the living organism of the city.

Many dryland regions contain archaeological remains which suggest that there must have been intensive phases of settlement in what now seem to be dry and degraded environments. This book discusses successes and failures of past land use and settlement in drylands, and contributes to wider debates about desertification and the sustainability of dryland settlement.
