The article, A methodology for creating greenways through multidisciplinary sustainable landscape planning, by Selma Beatriz Pena and other colleagues (2010), discusses a precise method in particular to greenways by sustaining tourism areas. "Greenways are networks of linear elements that are planned, designed and managed for multiple purposes, including ecological, recreational, cultural, aesthetic or other purposes compatible with the concept of sustainable land use" (p.971). By using landscapes in a cultural and natural process that does not have detrimental environmental effects, interpretation, knowledge and understanding is required for the sustainment of tourism areas. Landscape is a complex concept and system that is the result of the combination of natural and human force factors. The cultural and natural elements were incorporated through an ecological structure that is the product of natural and fundamental systems. "The comprehension of environmental sensitivity can give way to sustainable development by supporting decisions regarding interventions from ecological, economic and social perspectives." (p. 971) By the positive and helpful use of landscape alongside with steady use, the management of the environment will continue to become known and more effective.
