ABSTRACT
This chapter shines a light on Nature-based Solutions, which enable nature’s reinstation into the built environment by increasing natural habitat areas via green walls, roofs, blue infrastructure and wildlife corridors, among other features. It acknowledges the importance of trifurcated coexistence of nature, people and the built environment – especially in growingly densified urban areas, where the survival of local habitats are increasingly jeopardised. The chapter concludes with Sustainable Food Production and Urban Food Systems where health, environmental and socioeconomic benefits, as well as challenges of these systems on resource and energy efficiencies are discussed. Land use involves modification of the natural environment for human uses, and with its international and intergenerational implications, it shapes the prospects of food, water and health security all around the world. In cities today, less than 2% of the valuable nutrients gets circulated back to a productive use.
