\u2206 To combat urban floods, it is necessary to use new water management systems and convert Chennai into a sponge city.<\/p>\n\n\n\n
\u2206 The idea behind sponge cities is to make cities more permeable, with more open spaces to collect rainfall and enable it to sink into aquifers.<\/p>\n\n\n\n
\u2206 The city’s Water Resources Department is considering the potential of drilling recharge holes in smaller water bodies.<\/p>\n\n\n\n
\u2206 Sponge city is a novel urban construction model that aims to improve flood control while also strengthening ecological infrastructure and drainage systems.<\/p>\n\n\n\n
\u2206 In the year 2000, Chinese researchers suggested this hypothesis.<\/p>\n\n\n\n
\u2206 In the last few decades of growing urbanisation, sponge city strategies have been used more frequently in new construction than in rehabilitated complexes.<\/p>\n\n\n\n
\u2206 The Yanfang residential neighbourhood in Xiamen and Langang Park in Shanghai are two recent constructions that demonstrate this tendency.<\/p>\n\n\n\n
\u2206 Flooding has been a common occurrence in Indian cities.<\/p>\n\n\n\n
\u2206 In managing or reducing the recurrence of big floods in urban areas, India’s land policy has proved ineffective.<\/p>\n\n\n\n
\u2206 Cities lack an adequate drainage system.<\/p>\n\n\n\n
\u2206 Water is wasted due to concrete constructions in metropolitan areas.<\/p>\n\n\n\n
\u2206 Protection: Focuses on the city’s original environmentally vulnerable regions, like rivers, lakes, and ditches. The water environment is progressively treated and the damaged urban ecology is restored using natural plants, soil, and microorganisms.<\/p>\n\n\n\n
\u2206 Restoration: It includes identifying ecological patches, establishing ecological corridors, strengthening the linkages between the patches, forming a network, and outlining the blue and green lines to restore the aquatic biological environment.<\/p>\n\n\n\n
\u2206 Mandatory Measures: To conserve ecological patches, maintain their storage capacity, increase source management, and develop ecological sponges of various scales, mandatory measures apply to urban roadways, urban green spaces, urban water systems, residential areas, and special structures.<\/p>\n\n\n\n
\u2206 This technology aids in the reduction of urban floods, the urban heat island effect, and the scarcity of water supplies.<\/p>\n\n\n\n
\u2206 By absorbing and retaining rainwater and utilising it to decrease floods, it also benefits the ecology and wildlife.<\/p>\n\n\n\n
\u2206 Sponge city policies are nature-based solutions that capture, store, and filter water using natural landscapes.<\/p>\n\n\n\n
\u2206 This approach was inspired by an old understanding of climate adaptability, particularly in the monsoon area.<\/p>\n\n\n\n
