Tourism is one of the most dynamic industries and is a set of relationships and phenomena that occur when tourists come into contact with a tourist destination. Tourism is a strong factor in economic development. At the same time, tourism is the strongest branch of the Croatian economy. Sustainable development is a type of development that meets the current needs of society, considering the needs of future generations. Sustainable development guarantees a balance between society, economy and ecology. Sustainable tourism strikes a balance between making a profit and preserving the environment. Sustainable tourism benefits the local community, establishes social justice, preserves natural, historical and cultural heritage, protects the environment and uses resources in the right way. Integrated Coastal Zone Management (ICZM) is an ongoing process that implements sustainable development, preserves coastal areas and their biodiversity. The purpose of ICZM is to remove all threats arising from unsustainable development trends. The city of Zadar is an excellent example of sustainable development. The main goal of sustainable tourism development in the city of Zadar is the protection of rich cultural and historical heritage and stable tourist growth.
