 the communities developed a sense of pride of their own culture, but the tourists as well.
Negative impacts from CBT
The idea of CBT involves that the income is equally shared within the community, however, this is not always the case therefore, and an unequal income distribution takes place. Especially in larger communities it is a well-known phenomenon as not the whole community is equally attractive for tourists. Community members which live in the less attractive areas are often not involved in CBT. To generate a benefit for the whole community the income is often put in community projects to improve for example the infrastructure. If those community projects are only carried out in the tourism areas the members which live in the other parts of the community do not benefit from it.
Another negative impact can occur when the community members develop different ideas of how CBT should be carried out and how the operational processes have to be, as well, as how the different roles should be divided.
With an increase in tourism there is an increase in infrastructure development which is one the one hand a positive aspect, but on the other hand it causes negative influences on the nature, especially in the construction phase. Another problem of an increasing amount of tourists is the amount of waste generated. Some communities face a waste problem since they welcome tourists, as not all tourists are sensitive towards the issue of waste management and drop their waste everywhere. Another problem is that more waste gets generated and the community needs to be capable to take care of larger amounts of waste. 
Furthermore, in case tourist activities are not controlled, tourists might cause damage to the nature and the wild animals living in the community due to inappropriate behaviour.
If a community introduces CBT, the tourists arrive via they own vehicle or public transport. Thus, there is more traffic taken place in the community and more CO2 emissions are released.
In my point of view the greatest negative impact is that the host community might change towards the tourists and give up or lose over the time they own values, norms and daily activities, as they start living for the tourism and try to make it convenient for the tourists and to generate as much income as possible. Some research found out, that some community members start focusing a lot on their material status and value their own benefits over the benefits of the whole community.
While the exchange of culture is a positive aspect as described before, it can lead to a loss of cultural identity as well. As soon as people become aware of others values, norms and cultural activities, they might prefer those over they own ones. Therefore, it would be then a rather negative aspect. But not only the possible event of preferring another culture over the own culture can cause a loss of cultural identity. Another danger lays in the hospitality of the community. As already roughly mentioned before, the community might give up their own activities to fulfil all wished and demands from the tourists. If the community only lives to make the stay as convenient as possible for the tourists they will not be able any more to live their own life and culture and they might forget it over the time. One example for that is for instance the way of dressing. Normally, it is not respectful to dress in shorts which do not reach the knees and shirts which do not cover the shoulders. If tourists do not know about that or do not care and the locals are too afraid to say something and are faced over a long period with this issue, the younger generation might want to wear the same clothes or it simply does not matter anymore for the community and they lose this part of their culture.
How to shrink the possibility of negative impacts?
One way of ensuring that the rather negative impacts are not likely to happen is to set clear agreements and regulations. The focus should lie on long-term planning and the possible negative impacts should be taken into account to become aware of them and bein
