Review of Blue-Green Infrastructure in Some Selected Countries

Blue-Green Infrastructures (BGI) integrate solutions implemented to enhance water management and landscape values for more climate-resilient livable cities. It has created an opportunity renew the natural structure of balance in cities rural through increase rainwater retention enlargement permeable areas. The objective this review is assess blue-green infrastructures selected countries (Ethiopia, Japan, USA). BGI a driver biodiversity provides groundwater storage, stability systems, improvement quality, purification, water-related network service. also several benefits enhancing inland connections protecting marine ecological systems on global scale. They minimize effects climate change, techniques, provide important design tools sustainable regions, resilience flexibility infrastructure area social recreational activities. Currently, have been given due attention using different methods. To ensure efficient use subsurface water, Japan USA are increasing from current level thorough protection expanding availability green space, roofs, paving, other structural measures. Moreover, Ethiopia restored massive scale planting trees wise forests. Japan's eco-building Fukuoka Nagoya Strategy Biodiversity, Seattle working urban development plans, Ethiopian’s East Haarge Tigray some well-known BGI. In all countries, implementation transformation occurred under systematic conditions. best practices Ethiopia, will benefit people world if it good manner.
