In an era of global climate change and rapid urbanization, innovations on governance of urban systems are critically required as 50% people are now living in less than 3% of the earth’s urbanized terrestrial surface. Without careful production of knowledge, and large investments to link that knowledge to action, cities will be overwhelmed with environmental challenges. Both policy and science now emphasize the critical necessity of green areas within urban social-ecological systems. Here, we review the present status of urban forestry across the world, and draw lessons that can be applied for the governance of urban green spaces during the development of Jaipur as a world-class city in Rajasthan. We find wide variation both in coverage as well as per capita availability of green spaces. There are, however, some discernible trends emerging from cities renowned for their urban green spaces: approximately 20 to 30% coverage of the total geographical area, and 15 to 25 m2 urban green spaces per capita. World Health Organization suggests ensuring at least a minimum availability of 9 m2 green open space per city dweller. Finally, we provide strategies and lessons for connecting science to decision making aimed at creating multifunctional landscapes to enhance urban resilience and human well-being.
