URBAN FLOODING AND HUMAN SETTLEMENT


Urban flooding is the term used to describe the flooding of land or property within a constructed environment, especially in locations that are more densely inhabited (like cities), as a result of excessive rainfall that exceeds the capacity of drainage systems. Urban flooding, in contrast to country floods (heavy rain over flat or low-lying terrain), is a result of both increased precipitation and unplanned urbanisation (catchments).

Causes Of Urban Flooding: 

Encroachment on drainage channels; unplanned tourism; climate change; Unplanned release of water from dams; Illegal mining

Impact Of Urban Flooding: 

Loss of life and property; Negative impact on Ecosystem; Negative impact on Human and Animal Health; Negative Psychological impact.

Climate Change Impact On Costal India Cities: 

Cropland turning unfit for production; Rise in sea level; Species Extinction; Chronic water scarcity; Increase in incidences of extreme events; Loss of biodiversity; Urban Heat Island.

Climate Smart Cities Assessment And Its Impact: 

📌 To inculcate a Climate-Sensitive Approach to Urban Planning and Development, the Climate Smart Cities Assessment framework, for 100 smart cities, was launched by the Ministry of Housing and Urban Affairs. 

📌 The framework has 28 diverse indicators, across 5 categories namely (i) Energy and Green Buildings, (ii) Urban Planning, Green Cover & Biodiversity, (iii) Mobility and Air Quality, (iv) Water Management and (v) Waste Management.

Sustainable Cities India Program: 

📌 The National Institute of Urban Affairs (NIUA) and the World Economic Forum have signed a Memorandum of Understanding (MoU) to work together on a jointly developed "Sustainable Cities India programme." 

📌 It aims to create an enabling environment for cities to generate decarbonization solutions across the energy, transport and built environment sectors.
