Final answer:
High costs constitute a significant barrier to tourism planning, encompassing infrastructure development, transportation, and regulatory expenses. Remote locations such as island nations face particular challenges due to the added costs of limited transportation options. Moreover, poorly managed tourism can lead to environmental damage and limited local economic benefits.
Step-by-step explanation:
One of the barriers to tourism planning is that the costs of conducting tourism processes can be high. These costs can include investment in infrastructure like airports and hotels, the transportation of goods, and various forms of nontariff barriers such as regulations and inspections that increase the expenses. Particularly in remote locations like the Melanesian islands, transportation can be exceptionally expensive due to long distances and limited modes of access, which can include only aircraft or ship. In many cases, the high cost can be prohibitive for countries with limited financial resources.
Moreover, tourism can potentially cause environmental damage and fail to significantly benefit local economies due to issues like multiplier leakage, where profits are not retained locally. The challenge is further exacerbated by the potential for conflict between the ideal of rigorous and sustainable monitoring of resources and the practical realities in many developing countries. As such, poorly managed tourism not only imposes high financial cost but also risks long-term environmental and cultural damage. Acceptance of tourism methods also plays a role, where public opinion and potential resistance due to environmental and health concerns must be taken into account.
