Cumulative global transformations, occurring daily, affect important aspects of our life. Characteristic cultural and natural heritage, including sites of priceless value, is under constant threat. There are growing pressures, of both natural and human origin, such as wars, con icts, natural or technological disasters and the effects of global climate change. These provoke the continuous degradation of many sites included in the World Heritage List. In consequence, immediate strategic measures must be taken. Natural heritage is our legacy from the past, that we inherited from our ancestors and pass on to future generations. It is vital to realize its value and protect it by all possible means, enforcing innovative and sustainable action plans that promote global international co-operation. This book aims to address speci c natural heritage sites in Europe, from West to East. The six countries of study interest are Portugal, Malta, Greece, Italy, Romania and Turkey. For each case, the corresponding current status is presented. This is accompanied by recommended action plans for protection and conservation, tra- ing initiatives that improve the public awareness of natural heritage issues and efforts to estimate the natural/environmental value of the sites. The book is the overall result of an interregional initiative aiming to promote convergence, provoke public interest and recommend action for radical changes in our attitude towards heritage conservation.
