ReportInterventions on green space in urban settings can help address public health issues related to obesity, cardiovascular effects, mental health and well-being. However, knowledge on their effectiveness in relation to health, well-being and equity is incomplete. To explore the effectiveness of urban green space interventions to enhance healthy urban environments, the WHO Regional Office for Europe reviewed research findings, local case studies and Environmental Impact Assessment/Health Impact Assessment experiences, and assessed their impacts on environment, health, well-being and equity. This report provides the three working papers prepared for a meeting, and presents the discussion and conclusions on what intervention components have been found to be effective in maximizing the environmental, health and equity benefits derived from urban green spaces.
