Ecotourism has the eradication of poverty and environmental protection at its core. Both of these goals were established by the United Nations in 2012 though their development began in the 1980s. The purpose of this chapter is to analyse, using a comparative methodology, global and local eco-cultural tourism (natural, rural and urban areas) in tourist destinations of countries with emerging economies (Asia: China, Malaysia, Thailand), developed countries (Europe: Spain), and developing nations (South America: Peru, Argentina, Bolivia). The working hypothesis states that local, sustainable planning, endorsed by all the tourist agents is required, and should be led by the load capacity and the economic and environmental balance (green economies and ideologies), in order to answer to poverty and climate change problems by means of Tourist Projects directed by governmental policies and administrations. The outcomes suggest a need for a logistical change of policies, to prevent economies from generating pollution and carrying out abrasive activities associated with tourism. This change will create sustainable tourist destinations, the inclusion of populations, and the protection and conservation of natural and cultural heritage.
