Try this question:      

Q.Urban water resources management is an uphill task for Indian cities. Discuss.

What is Green-Blue infrastructure?

  • ‘Blue’ infrastructure refers to water bodies like rivers, canals, ponds, wetlands, floodplains, and water treatment facilities; while ‘Green’ stands for trees, lawns, hedgerows, parks, fields, and forests.
  • The concept refers to urban planning where water bodies and land are interdependent, and grow with the help of each other while offering environmental and social benefits.

How does DDA plan to go ahead with it?

  • In the first stage, the DDA plans to deal with the multiplicity of agencies, which because of the special nature of the state, has plagued it for several years.
  • DDA wants the first map out the issues of jurisdiction, work being done by different agencies on drains and the areas around them.
  • Thereafter, a comprehensive policy will be drawn up, which would then act as the common direction for all agencies.

Why such a policy?

  • Delhi has around 50 big drains (blue areas) managed by different agencies, and due to their poor condition and encroachment, the land around (green areas) has also been affected.
  • DDA, along with other agencies, will integrate them and remove all sources of pollution by checking the outfall of untreated wastewater as well as the removal of existing pollutants.
  • A mix of mechanized and natural systems may be adopted, and dumping of solid wastes in any of these sites will be strictly prohibited by local bodies, through the imposition of penalties.

Major features

  • The land around these drains, carrying stormwater, will be declared as special buffer projects.
  • The network of connected green spaces would be developed in the form of green mobility circuits of pedestrian and cycling paths.
  • It will be developed along the drains to serve functional as well as leisure trips.

Challenges ahead

  • The biggest challenge is the multiplicity of agencies.
  • Secondly, cleaning of water bodies and drains has been a challenge for agencies in Delhi for years now.
