International
International mostly means something (a company, language, or organization) involving more than a single country. The term international as a word means involvement of, interaction between or encompassing more than one nation, or generally beyond national boundaries. For example, international law, which is applied by more than one country and usually everywhere on Earth, and international language which is a language spoken by residents of more than one country.
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
Tourism
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. Tourism may be international, or within the traveller's country. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purposes".
Travel
Travel is the movement of people between distant geographical locations. Travel can be done by foot, bicycle, automobile, train, boat, bus, airplane, or other means, with or without luggage, and can be one way or round trip. Travel can also include relatively short stays between successive movements.

Slow travel now rivals the fly-to-Barcelona-for-lunch culture. Advocates savour the journey, travelling by train or boat or bicycle, or even on foot, rather than crammed into an airplane. They take time to plug into the local culture instead of racing through a list of tourist traps.

David Attenborough has said that Bali is the most beautiful place in the world, but he must have been there longer than we were, and seen different bits, because most of what we saw in the couple of days we were there sorting out our travel arrangements was awful. It was just the tourist area, i.e., that part of Bali which has been made almost exactly the same as everywhere else in the world for the sake of people who have come all this way to see Bali.

I've taught the better class of tourist both to see and not to see; to lift their eyes above and beyond the inessentials, and thrill to our western Nature in her majesty.
