Role of Blue-Green Infrastructure in Achieving Sustainable Development Goals in Urban Centres of Developing countries

The central idea for establishing the 2030 agenda for sustainable development is achieving well-being for all while protecting the environment and welfare for future generations with 17 interlinked Sustainable development goals (SDGs). These goals are no poverty, zero hunger, good health and well-being, quality education, gender equality, clean water and sanitation, affordable and clean energy, decent work and economic growth, industry, innovation and infrastructure, reduced inequalities, sustainable cities and communities, responsible consumption and production, climate action, life below water, life on land, peace, justice, and strong institutions, and partnerships for the goals. To achieve these goals blue-green infrastructure (BGI) can play a vital role as it promotes sustainable and resource-efficient living. Utilizing urban planning, ecological restoration, and infrastructure to foster a sense of community with the natural world, the BGI network offers the “ingredients” for resolving urban and climatic concerns. Under BGI the water bodies like rivers and tanks are indicated by the color “blue.” and for trees, parks, and gardens, use “green.”. BGI has numerous advantages and produces effects that cut across the economic, social, and environmental sectors. It contributes to the control of regional ecosystems as well as the reduction of pollutants and urban temperature. These in turn have a significant economic impact, for instance, terrace gardens encourage lower building surface temperatures, which reduces the need for cooling and, consequently, the demand for energy and power. Reduced consumption of vital raw materials and resources, the prevention of pollution, and a decrease in carbon emissions are further financial and economic advantages. This chapter reviews the applicability of BGIs in achieving SDGs at the ground level and further highlights the implications, benefits, and challenges of their implementation. It is known that an effective and efficient infrastructure like BGI allows multipurpose uses and several advantages that directly or indirectly help to meet the targets in order to achieve the SDGs.
