Last date for submission of paper: unknown; Contact person: unknown; Tourism is important not only for economic development, but also for fostering peaceful cooperation among different societies, cultures and nations through cross cultural and social harmony. However, peace is also a pre-condition for the development and growth in the tourism sector. A GDP focused economic development model has often caused tremendous pressure on finite natural resources, leading to an alarming rate of environmental deterioration and resulting resource conflicts in the world. Thus, peace and the environment have an intricate relationship, and tourism is both an instrument and casualty when peace is diminished. In addition to these relationships, peace, tourism and the environment are components of national and international initiatives including Nepal 2020 and the 2030 Sustainable Development Goals.
