Green infrastructure leads to adaptation and even transformation of future and faces challenges such as climate change, food insecurity and limited resources . Cairo ecosystem faces a lot of challenges that may affect the urban, cultural, heritage, economic and environmental aspects of one of the oldest capitals of the world. Biodiversity in Cairo is a key element could help in implementation of Multifunction green infrastructure strategy despite of all culture and awareness challenges . The research methodology is divided into a theoretical review that discusses main concepts related to Green infrastructure such as: Landscape Sustainability, Ecosystem Services, Landscape Services, Multifunctional Landscape, Urban Green space, Green infrastructure and a field study conducted by the author upon which the action plan was based.enMultifunctionalGreen infrastructureUrbanEcosystemArticle
