On the 2021 Global Mayors Challenge
The 2021 Global Mayors Challenge welcomed our first ever global cohort of 15 cities and asked cities to bring forth innovations that emerged during the Covid-19 pandemic or were inspired by it. Click through the gallery below to see some of these ideas come to life.
Pictured here, Shanti Mahato, a farmer from a village in the Sundargarh district of Odisha, India, owns three acres of land where she grows seasonal vegetables, such as pumpkins, tomatoes, and okra. Once harvested, Shanti brings them to the nearby market to sell to residents; however, lacking a cold storage unit, Shanti is often forced to discard her produce or sell them for a fraction of the price. As one of the first users of the cold storage room, Shanti has been able to preserve leftover items in the storage unit and sell them during the next market day. She is also able to grow more vegetables to sell to multiple markets, and other small vendors.
Rourkela
Idea at a Glance:
Winner of the 2021 Bloomberg Philanthropies Global Mayors Challenge for the city's solar-powered cold storage rooms. The cold storage facilities provide local farmers with a place to store their market produce safe from the heat, which in turn increases produce market viability and farmer income. The cold storage rooms are run by groups of women entrepreneurs and provide women's economic development opportunities at the nexus of agriculture, economy, and renewable energy.
Pictured is caregiver Librada Rincón Ortiz, 51, with her mother, Maria Del Carmen Ortiz de Rincón, 81. When Maria was diagnosed with Parkinson’s disease, Librada left her job at a local clothing company and began to sew clothes from home to provide for her mother and seven children of her own. Guided by care experts, Librada works through therapeutic exercises with her mother, building caregiving skills and earning certifications through the care block program that can later be used as proof of working experience for future job searches.
Bogotá, Colombia
Idea at a Glance:
Winner of the 2021 Bloomberg Philanthropies Global Mayors Challenge, Bogotá developed a Care Block program designed to reduce women’s unpaid care work, spark cultural shifts that redistribute care more equitably across family units, and formally recognize the skills of family caregivers. In Bogotá, the unpaid care burden falls disproportionately on women, with 30% of the city’s female population providing full-time caregiving, 14% of whom cannot leave their homes due to the conditions of those for whom they care. The Care Block program provides in-home support to people in need of care in Bogotá, which in turn alleviates the often consuming burden of care that disproportionately falls on women.

Idea at a Glance:

Freetown, Sierra Leone
Idea at a Glance:
Winner of the 2021 Global Mayors Challenge, the city of Freetown, Sierra Leone, is providing monetary incentives for communities to plant, track and care for living trees to establish a tree-trading market that funds reforestation and supports local livelihoods. Over the past 50 years, Freetown has experienced rapid population growth which has resulted in the loss of millions of trees due to urban development. To counteract these tree losses, Freetown the Treetown harnesses the power of digital tools and community stewardship to replenish ecosystems and protect residents now and for generations to come.
Pictured here are volunteers and staff of Istanbul Metropolitan Municipality assembling and delivering earthquake relief packages to those affected by two devastating earthquakes with magnitudes 7.7 and 7.6 that occurred in southern Turkey on February 6, 2023. According to official data, the earthquake killed over 50,000 people across 11 provinces and left roughly 1.5 million people homeless. Along with the human suffering, the earthquake also resulted in a major economic toll on the region. With Pay It Forward already in place, the City of Istanbul together with the innovation team and assistance from the Bloomberg Philanthropies Global Mayors Challenge, quickly pivoted Pay it Forward – which had already expanded since COVID-19 to help other specific needs: students needing educational support, the ones in the need of transit help, families seeking diapers and other necessities – with the added capability of allowing direct, peer-to-peer donations of supplies to get from anywhere in Turkey to families displaced by the disaster.
