Pollination is one of the most important ecosystem services. Of about 200,000 species of animals that provide pollination as a service, >90 % are insects. They pollinate 75% of the world’s food crops. However, there has been a steady decrease in the health of the pollinator community worldwide (15-40%). Major drivers responsible for this are urbanization, habitat loss, pollution and climate change. With nearly half of the world’s population now living in cities, the overall landscape is fast-changing. Habitats in natural areas have decreased, but terraces and backyard gardens have increased. The present case study from Pune City, India, which is situated along one of the most urbanized belts in Asia, highlights how urban terraces and backyards can become potential habitats for pollinators. Systematic planning of key plant species (> 50), including wild and cultivated plants (herbs, creepers, climbers, vegetables) centered around a carefully designed yearly floral calendar, resulted in visits from and colonization by more than 30 species of butterflies and 20 species of bees, flies, wasps, ants and birds. Broad-leaved species were used as nesting habitats by birds like tailorbird (Orthotomus sutorius) and ashy prinia (Prinia socialis). Bamboo sticks used for supporting climbers acted as nesting sites for solitary bees. To date, urban terraces have been overlooked as potential habitats to protect and promote biodiversity. However, with an increasing interest in terrace gardening among common citizens, we feel that this can become a replicable and scalable model for maintaining a healthy pollinator community in urban areas.
