Also, the environment highlights the fact that the wildebeest migration relies on both nations for its existence. That is to say, the use of wildebeest resources depends on both local planning at the scale of Masai Mara National Reserve and Serengeti National Park, as well as national planning at the level of the Kenya Wildlife Planning Corporate Plan and Tanzania National Park Corporate Plan. This chapter underlines the significance of participatory planning for sustainability at global, regional, national, destination, and attraction levels in the context of responsible tourism. In the framework of responsible wildlife tourism, it makes clear the mutually beneficial relationship that exists between sustainability and protected areas. It also underlines the necessity of laws, monitoring, and assessment of wildlife tourist operations in line with the philosophy of sustainable development. The consumption of resources without scientific and participatory planning causes damage to the economy and wildlife ecosystem. Successful and feasible plans usually depend on appropriate integration across various national, regional, international, and ethnical scales, which is important for managing national and transboundary wildlife resources. Without proper and devoted implementation techniques, sustainable wildlife tourism may develop in a haphazard way. As a result, it is mandatory for certain governments for each protected area to have a management plan that technically and legally guides resource utilization and conservation at the attraction and destination levels. Most of the management plans are developed in the participatory approaches by incorporating many key wildlife stakeholders. Such plans provide the basis for managerial decisions and future directions of the protected areas. Furthermore, the management plans may have management zones outlining and limiting the execution of specific operations based on resource sensitivity and availability. Planning is crucial for reducing negative consequences on sensitive resources and endangered species. The systematic planning process in wildlife tourism occurs as a lengthy and cyclic process, not as an event. It involves every essential wildlife tourism stakeholder and follows all the necessary but scientific participatory planning processes. A proper and participatory planned sustainable wildlife tourism provides accurate information to stakeholders and maximizes the quality, accessibility, safety, and security of tourism products and services at the destination. Consideration of the expectation, safety, motivation, interest, and satisfaction of wildlife tourists is one of the outcomes of a well-planned sustainable wildlife tourism.
