Butterfly corridor
This project aims to create a Butterfly corridor through the city of New Delhi by connecting local parks, residential gardens, biodiversity parks, and major forest areas (Ref 1, 2). For this, various locations, mainly maintained by citizens, are developed as habitats for the butterflies by planting various kinds of host plants which can be used to lay eggs. Overall, about 100 butterfly corridors are planned to be developed over time (Ref 3). The project is initiated by the Conservation Education Centre (CEC), a Delhi-based faction of the Bombay Natural History Society. With the help of CEC, community custodians of the gardens are trained to develop butterfly parks. A number of public and private land areas have now been designed as butterfly corridors throughout the city (Ref 1).
An underlying aim of the project is to allow butterflies to travel across locations, thus allowing genetic diversity among populations (Ref 1). The project has also helped educate the community about the importance of maintaining a healthy butterfly population. Through the organization of Butterfly month in September every year, citizens and, especially young kids, are encouraged to learn about butterflies through butterfly walks, counting, and photography contests, among other activities (Ref 1, 5).

Mangrove Ecosystem: Community environmental awareness
The Mesurado mangrove forests, which is the focus point of the intervention, covers an area of approximately 6,760 hectares. It is situated within Montserrado County, around Monrovia, the capital city of Liberia, West Africa. It is surrounded by 38 human settlements some of which are regarded as slums. The area is currently one of those five Ramsar (Iranian city wherein 1971 was signed and ratified the Convention on Wetlands) designated sites in Liberia and a home of three species of mangrove that stands at the point of extinction due to human encroachment. (3) Adding to this, the area is used as a colossal waste dump, and, in cases, for cutting of mangrove trees for fish drying. In addition to the huge species richness of the area, it also serves as a habitat and breeding ground for marine species and provides a number of important ecosystem services. This intervention seeks to address the issue of ignorance on the part of the communities about the importance and benefits of mangroves in communities within and around the Mesurado wetland. As it is a soft measure project, the main implementation strategy includes a series of educational episodes through a system of religious conservation awareness and education and alternative livelihood options for the communities engaged.

"Let's return the rivers to the city" campaign
In 2019, the public initiative "Let's return the rivers to the city" campaign united public forces around the Podborenka river, which flows through the territory of Izhevsk along its entire length [1, 4, 5]. In an urbanised environment, the river was abandoned due to water pollution, poor treatment of stormwater, road and industrial runoff, soil erosion, and due to presence of landfills in the valleys [1, 4, 7]. Therefore, the project's primary goal is to increase the efficiency of urban resources and the creation of new scenarios for resource use on the example of the space of the riverbed of a small river [3]. The project implementation contributes to improving the ecological situation of the Podborenka River, its embankment zone and biodiversity [1, 9]. Also, the project implementers paid particular attention to the education of young people, the development of volunteer movements, and raising the level of the ecological culture of the population [1, 2, 6, 7].
Urban and Peri-urban lake restoration
Taru Leading Edge initiated a lake conservation project in Indore with support from the Rockefeller Foundation and Indore Municipal Corporation as part of the Asian Cities Climate Change Resilience Network (ACCCRN).
Urbanisation and the increase of impermeable surfaces reduced the capacity for groundwater recharge. The climate change risks indicate increasing rainfall variability and more intense and/or more frequent storms as well as an increase in dry periods. With less permeable soils the city needs to optimally use existing lakes to capture runoff, creating buffer supplies and helping to increase groundwater recharge. The main objective of this project was “ensuring availability of local water resources during emergencies”, through developing a replicable model for peri-urban lake rejuvenation and conservation. The expected outcomes of the project include a stakeholder-managed process for stabilising/improving the water quality of the restored lakes and generating interest among multiple stakeholders to conserve urban lakes. TARU has restored and worked on 2 water bodies, demonstrating methods and processes required to revive lakes that have co-benefits of groundwater recharge, aesthetic enhancement of the area, cool microclimate and possible livelihood restoration. The names of the lakes restored are Khajrana talab and Lasudiya Mori talab. [2, 4]

Water Fund Mexico
Mexico City's (CDMX) Water Fund was established in 2015 by The Nature Conservancy Mexico on behalf of the Latin American Water Funds Partnership aiming to reduce the imbalance of the aquifers providing significant water supply for the territory of the CDMX and promoting positive long-term water balance (1). "The Water Fund emphasises good science in relation to the selection of sites and interventions, and in comprehensive monitoring. It seeks to make the business case demonstrating that these activities show returns with respect to water security" (1 p22). The first pilot project of the CDMX Water Fund engages small-scale producers in sustainable agriculture practices, works to restore and conserve water-absorbing land and reconvert land to water-friendly agriculture practices (1)
Atlantis Water Fund Pilot Project
The Nature Conservancy established the Cape Town Water Fund in 2016 using the worldwide applied water fund to enable downstream water users to invest in land conservation and restoration upstream. (4,5) In 2018, the Water Fund started its pilot project on the catchment area of the Atlantis Aquifer, outside of Cape Town's boundaries on state land. The pilot project "seeks to increase water supply to Cape Town by removing invasive plant species in water catchment areas. Invasive species have been found to use significantly more water than indigenous species and uptake millions of litres of water from the catchment area annually that would otherwise be added to the city’s water supply" ( 1 p7). The intervention also supports the empowerment of marginalized communities by providing training and employment for them. As one of the main characteristics of the water fund model, various local stakeholders from all sectors are invited to develop and implement water connected challenges (1).
Parc Marianne ecodistrict
Parc Marianne is an ecodistrict that aims to address multiple challenges such as climate action for adaptation, environmental quality, flooding, and in response to the high population growth in Montpellier. Parc Marianne is connected to public transportation, has bicycle lanes and car parks, and the sidewalk is shared between pedestrians and bicyclists and structured with trees and other greenery. The park was certified with the ecodistrict label in 2015 following requirements like environmental sustainability, thermal performance, quality of life, nature and biodiversity, and mobility (Ref. 1). Parc Marianne is a mixed neighbourhood with an ability to combine city and nature, quality of life and centrality (Ref. 2).
Park Museum Vrana
Initially the park was created in 1903 as a summer residence for the royal family and had a no-visitor’s policy. For over 40 years the park collected 821 trees, shrub and, grass species from all over the world on less than 100 ha. After the estate was given back to the successors of Tsar Boris III, they partially donated the park to Sofia municipality and in 2013 the park-museum ‘Vrana’ was opened for visitors. Due to its rare species, well-preserved wilderness and historical significance, the park enjoys great interest from tourists as well as scientists as a biodiversity hotspot. (Ref 1)
"I Have A Bee" Organisation
‘I have a bee’ (IHAB) is an organisation for hobby beekeepers. It contributes to a sustainable and long-term solution to the bee colony collapse phenomenon by popularizing bee keeping as a hobby. It was founded by 3 hobbyist beekeepers back in 2014. The idea originated from their passion for beekeeping and the desire to breed and keep bees as pets. The group has engaged in research about the roots of traditional beekeeping and designed a new top bar hive which has the advantage of being usable in backyards or on city terraces. (Ref 1) Their 1,000,000 beehive initiative aims to ignite 1,000,000 people around the world to watch at least one beehive. (Ref 3) No information found on status of project as of September 2020.
New traditional meadow orchards in Wuppertal
Meadow orchards with fruit trees were an integral part of subsistence farming and form part of the cultural heritage of Wuppertal. To preserve and further develop these meadows as an important habitat for flora and fauna and promote their potential for sustainable consumption, 4 such meadows were sponsored, maintained and promoted by the city of Wuppertal in close collaboration with the working group for fruit meadows via events, communal harvesting activities and hands-on courses since 1999. Since 2015, these meadows have increasingly drawn the attention of "foodsharing" movements and during the nationwide research year "future town". (Ref. 1, 2, 6, 8). Enclosed between areas of intensive conventional agriculture and the federal motorway, the orchards as islands of biological diversity are important places of retreat and relaxation. (Ref. 5) Communal activities are also offered, such as the co-creation of “edible experience spaces”, joint harvesting and providing a base for additional social projects (Ref. 6).
