Short description of the intervention
Delhi Development Authority (DDA) has established a network of Biodiversity Parks in Delhi with unique landscapes that harbour a diversity of plants, animals and microbes living in ecologically sustainable biotic communities and rendering multiple ecological services. Presently there are seven Biodiversity Parks developed by DDA located across the landforms of Delhi. These parks have a mosaic of habitats with rich floristic and faunistic diversity that function as a dynamic ecosystem. They have ecosystem processes such as organic matter decomposition, regeneration of plants, pollination, resting and nesting of birds and colonisation by other animals. The biodiversity parks in Delhi have proved to provide extreme essential services by creating ecological corridors and maintaining the genetic diversity in an urban setup. Furthermore, these parks have shown substantial potential in storing carbon and other pollutants and help in mitigating climate change. [2, 3]

Goals of the intervention
The overarching goal is the conservation and preservation of ecosystems of the two major life-supporting systems of Delhi, the river Yamuna and the Aravalli hills. The more detailed goals are:
1. To conserve biodiversity, especially the native biodiversity of Delhi and to protect the natural heritage of the ridge and river basin.
2. To establish field gene banks for threatened landraces and wild genetic resources.
3. To develop a mosaic of treatment and catchment wetlands that not only improve the water quality of untreated sewage but also sustain the rich aquatic flora and fauna of the Yamuna and monitor short term and long term changes in the ecology of the Delhi region.
4. To render multiple ecological services including carbon sequestration and recharge of groundwater aquifers.
5. To create educational and recreational benefits for the urban society. [2, 3]

Implementation activities
The Biodiversity Parks were developed on two types of landforms in Delhi, the floodplain of the river Yamuna and the rocky and sloppy terrain of the Aravalli mountain region. Biodiversity Parks at the floodplains have wetlands, marshes, swamps, islands, shoals, lakes, floodplain forests and different biotic communities native to the area. Additionally, constructed wetland systems were developed, which created a mosaic with patches of grasslands, forests and marsh communities. Visitors' zones with conservatory of herbal plants, butterflies, sericulture zones, and field gene banks have been developed. In the mountenous region and ridge, edaphic communities, shrublands, bulbous and succulent plants of rocky habitat, grasslands and savannahs were developed. Wetlands and lakes in the area were restored back. Also, visitors' zone were created with conservatories of medicinal plants, butterflies, fernery and many more. In addition to this, viewing points for animals were also created. [3]

Please specify the roles of the specific government and non-government actor groups involved in the initiative
The development of DDA Biodiversity Park was undertaken by joint collaboration with the Centre for Environmental Management and Degraded Ecosystem (CEMDE), the University of Delhi, with a provision for the recruitment of the requisite staff by the University of Delhi for Delhi Biodiversity Foundation, a committee to oversee the development of the Biodiversity Parks. The Chairman of the Foundation is the Lt. Governor of Delhi and it has an executive committee, which is chaired by the Vice-Chairman, DDA. The executive committee looks after the day to day activities in the Biodiversity Parks. The University is entrusted with the development of the parks with scientific staff. The landscape department prepares conceptual maps and the engineering department executes the works on ground. [3]

Please specify technological innovation
The government has donated vacant and barren lands to turn into biodiversity conserving areas. Trees were planted, and wetlands were constructed in some areas. [3]
Please specify social innovation
For the project to be implemented successfully and for maintenance, Delhi Biodiversity Foundation was established under the Delhi Development Act, 1956. Also, a close collaboration was developed between the Delhi Development Authority (DDA) and the University of Delhi. This needed creation of a governance body with staff from both organisations. [1, 2]
Please specify novelty level of the innovation
The Biodiversity Parks are the first of their kind in the world. Under the project, The Yamuna Bioversity Park was the first to be inaugurated in 2004.
Please specify Replicability/Transferability
The successful establishment of the Biodiversity Parks grabbed the global attention for replication as a model for urban environmental sustainability and resilience. These have a very high potential for fighting climate change and preserving urban biodiversity and could be replicated in other parts of the world without much adaptation. [2, 3]
Impacts, benefits
Description of environmental benefits
1. Biodiversity Parks act as heritage sites and repositories of the approximately 50 threatened communities of the Yamuna river basin and Aravalli hills. The parks have shown significant improvement in species variety in the area. A few rare and valuable species have been sighted in the parks over the years. The parks are home to thousands of plant and animal species including flowering plants, reptiles, birds and mammals. The Yamuna Biodiversity Park alone has 2000 species of plants and animals living in some 20-25 biotic communities having three trophic levels and a diverse food web including 60 species of butterflies, 50 species of dragon and damselflies, 200 species of birds and mammalian herbivores and carnivores.
2. The Biodiversity Parks provide ideal alternative habitats for migratory and resident bird species. The authority also provides special attention to the threatened and valuable species, including both animal and plant species. These species are protected and conserved in the parks. The wetlands attract more than 5000 migratory ducks from Siberia, Central Asia and Europe each year in winters.
3. The wetlands in the parks enhance groundwater recharge, impound floodwaters and augment freshwater availability. They also act as sinks for CO2 and other pollutants. This helps in lessening local weather conditions and buffering ambient temperatures. The wetlands have created a mosaic of Blue-Green-Infrastructures, which has established connectivity across regeneration sites.
4. In addition to the wetlands, the native trees have shown massive potential in capturing carbon and controlling the local climate. With various forest layers, the parks were enabled to create many micro-habitats allowing many animal species to find shelter, survive and breed. The grasslands provide a unique ecosystem that leads to the protection and conservation of soil.
5. Furthermore, the Biodiversity Parks serve as gene pools and represent unique ecological models possessing not only wildlife and natural values but also aesthetic, environmental and educational values. [2, 3]
Economic impacts
Description of economic benefits
The redeveloped areas with visitors' access bring many tourists to the parks and promote sustainable and educational tourism. [2. 3]
Description of social and cultural benefits
1. The Biodiversity Parks promote eco-tourism and social connectivity across the urban community, which has caught the attention of many residents and students from the local college and universities. The visitors' areas with viewing points for birds and other animals are also very popular among nature lovers.
2. The project has transformed and protected previous barren and neglected lands into a natural heritage, which provides very important ecosystem services to the community and beyond.
3. The parks also arrange educational events and spread awareness among the residents about native flora and fauna.
4. In addition to the University of Delhi, other local educational institutes arrange visits and guided tours in the parks for students to learn about NBS and the services they provide.
5. The University of Delhi in collaboration with the DDA conducting scientific research on biodiversity, gene pool protection and the role of wetlands in storing carbon. [2, 3]
