I was looking a good definition about pro poor tourism and I found a good webpage: www.propoortourism.org.uk.  The page is not working at this moment but you can find a lot of interesating working paper about the subject.

Definition of Pro-Poor Tourism (PPT)

Is tourism that results in increased net benefits for poor people. PPT is not a specific product or niche sector but an approach to tourism development and management. It enhances the linkages between tourism businesses and poor people, so that tourism’s contribution to poverty reduction is increased and poor people are able to participate more effectively in product development. Links with many different types of ‘the poor’ need to be considered: staff, neighbouring communities, land-holders, producers of food, fuel and other suppliers, operators of micro tourism businesses, craft-makers, other users of tourism infrastructure (roads) and resources (water) etc. There are many types of pro poor tourism strategies, ranging from increasing local employment to building mechanisms for consultation. Any type of company can be involved in pro-poor tourism – a small lodge, an urban hotel, a tour operator, an infrastructure developer. The critical factor is not the type of company or the type of tourism, but that an increase in the net benefits that go to poor people can be demonstrated.
