Sürdürülebilir turizm, turizm olayının var olmasını sağlayan kaynakların korunarak gelecek nesillere aktarılması olarak ifade edilebilir. Bir başka deyişle sürdürülebilir turizm, turistik arzın ve talebin sürekliliğinin sağlanmasına çalışılması olarak ifade edilebilir. Sürdürülebilir kalkınma kavramının beraberinde getirdiği bu anlayış, turistik üretimin ve tüketimin ekonomik sürdürülebilirlik, çevresel sürdürülebilirlik ve kültürel sürdürülebilirlik faktörlerini dikkate alarak yapılmasını amaçlamaktadır. Sürdürülebilir turizmi oluşturan bu faktörler birbirini etkilemekte ve birbirinden etkilenmektedir. Turizm olayını kültürel ögelerden ve çevresel güzelliklerden ayrı bir ekonomik sektör olarak düşünmek doğru olmayacaktır. Turizm işletmeleri açısından sürdürülebilirliğin sağlanmasına bağlı olduğu söylenebilir. Bunun yanında turizm işletmelerinde ekonomik sürdürülebilirliği etkileyen bir diğer etmen ise dünyada ya da destinasyonun bulunduğu ülkede yaşanan doğal, ekonomik, siyasi ve politik olaylar yani krizlerdir. İçerisinde fırsatlar ve tehditler bulunan krizler işletme yönetimleri için oldukça önemli bir konu haline gelmektedir. Bu bağlamda kriz yönetimi, kriz ortamında yöneticilerin davranışları ve stratejileri üzerinde durulması gereken önemli bir konudur. Turizm sektörü açısından krizler sektörde yer alan işletmeler açısından son derece önemlidir. Bu amaçla bu çalışmada ekonomik sürdürülebilirliğin önünde ki en önemli engellerden birisi olan ve özellikle son yıllarda yaşanan krizler ile turizm işletmelerinde krizlere karşı alınabilecek önlemler incelenmiş ve değerlendirilmiştir. Çalışmada turizm işletmelerinde kriz ortamında ekonomik sürdürülebilirliğin sağlanması için alınan veya alınabilecek önlemler; stratejik önlemler, üretim ve pazarlama stratejileri, yönetim ve organizasyon stratejileri ve finansal önlemler olarak ele alınmıştır

Sustainable tourism can be expressed as preserving the resources that enable the existence of the tourism event to be transmitted to future generations. In other words, sustainable tourism can be expressed as an attempt to provide touristic supply and demand continuity. This understanding brought about by the concept of sustainable development, aims at making tourism production and consumption taking into consideration the factors of economic sustainability, environmental sustainability and cultural sustainability. These factors, which form sustainable tourism, affect each other and are affected by each other. It would not be right to think of tourism as an economic sector separate from cultural objects and environmental beauty. In terms of tourism businesses, economic sustainability depends on ensuring environmental and cultural sustainability. In addition to this, another factor affecting economic sustainability in tourism enterprises is the natural, economic, political and political events in the world or the country in which the destination is located, namely crises.

In terms of tourism businesses, economic sustainability depends on ensuring environmental and cultural sustainability. In addition to this, another factor affecting economic sustainability in tourism enterprises is the natural, economic and political events in the world or the country in which the destination is located, namely crises. The crisis can be defined as the moment of decision, the unexpected and unpredictable, which weakens the operator’s solvency, affects its performance, the tension that threatens the existing values and aims of the organizations that need to be answered suddenly. Crises containing opportunities and threats are a very important issue for business management. Rapid transformations in environmental factors in the global competitive environment cause enterprises to face situations that can be described as a crisis. Crises emerge due to a variety of factors and affect businesses in the negative direction. Crises may arise from national or international reasons, as well as from the business itself or the sector to which the operator is affiliated. Regardless of the scale, all businesses that have a large economic importance are affected by crises in different dimensions. Although the effects and violence are different, the business world is always confronted with crises. One of the world's fastest growing sectors, the tourism sector, is one of the major problems today is crises. The crisis in the tourism sector can be expressed as any event that occurs suddenly, has the potential to affect the tourism industry directly or indirectly, occurs naturally or is carried out by people. The crises that have taken place around the world have negative effects on the tourism sector. Economic crises in any country in the world have a negative impact on other countries that have economic relations with countries affected by the crisis. The local and global crisis in recent years has directly and indirectly affected the tourism industry and businesses operating in the tourism sector. In addition, thanks to developing technology and communication, an event happening elsewhere in the world can be spread all over the world in a short time. Even the hearing of such incidents causes the cancellation of reservations and events, which causes the tourism sector to be negatively affected. Tourism businesses are economic, social, cultural, political, international environment etc have a sensitive structure against the factors that may cause crises. The unique features of the tourism sector make the crisis issue more important in terms of tourism operations. Tourism, however, is in contact with many different industries, and it is likely that businesses operating in the sector are likely to face a crisis once it is considered that crises can occur in other sectors at any moment. In addition, a labor-intensive industry and that the excessive number of industry as it relates to tourism brings to a more open position on the crisis compared to other sectors. It can also be assumed that the impact of the crises on the tourism sector depends on the demand for tourism. Tourism demand, threatening consumer's safety of goods and life (war, terror, armed attacks, epidemics, natural disasters, etc.), suddenly emerging events, economic crises that reduce economic income and it is extremely sensitive to political changes and developments that hurt the image of tourists. The part of the income allocated for tourist expenses, as long as it is the part that remains after meeting the personal needs of people, the decrease in income due to economic crises has reduced the possibility of participation in tourism activities. The fact that touristic consumption is not a necessary consumption is one of the most important problems that the tourism sector has experienced during times of crisis. Nevertheless, it seems that the demand for destinations losing sight of a safe place or politically it can be prevented by the demands of a destination has fallen. For these reasons, enterprises in the tourism sector are more likely to face the crisis. The ability of tourism enterprises to maintain their existence depends on the economic sustainability of their business activities. For this reason, ensuring economic sustainability in tourism enterprises is an important issue. One of the biggest obstacles to tourism in this regard is the crises experienced in the sector or other sectors. In this context, it can be said that the sustainability of tourism enterprises depends on their ability to cope with the crises they face. The unique fragile nature of the tourism sector makes it more vulnerable to crises that directly or indirectly affect the sector and businesses. For this reason, crisis and crisis management are crucial in terms of tourism operations. At this point, the economical survival of businesses, that is, the measures that need to be taken or can be taken against the crises, has a great prospect for the future of businesses. For this reason, in this study the measures that can be taken and the strategies that can be applied in order to ensure economic sustainability of the tourism enterprises faced with the crisis and to sustain their existence have been conceptually investigated. These are covered under four headings as strategic measures, production and marketing strategies, management and organizational strategies and financial measures.
