Abstract
OBJECTIVE: The objective of this scoping review is to review the body of knowledge on net gain and no net loss (net-outcome) objectives and approaches applicable to health in spatial planning and development policies and practice. INTRODUCTION: There is an established body of academic and gray literature addressing environmental net-outcome objectives, such as biodiversity net gain, in spatial planning policies and practice. A "health net gain" objective has recently been proposed as a driver for health protection and the realization of health. Such an objective and approach are yet to be scoped and defined. INCLUSION CRITERIA: This review will consider sources in the scientific and gray literature that describe health net-outcome objectives that can be implemented in spatial planning and development policies and practice. Source contexts will not be limited to specific countries, geographical areas, or settings. All types of evidence will be considered. METHODS: This review will follow the JBI methodology for scoping reviews. Databases to be searched include PsycINFO, Embase, HMIC Health Management Information Consortium, MEDLINE (Ovid), Scopus, and selected databases from the ProQuest Social Science Premium Collection. Sources of gray literature to be searched include ProQuest Dissertations and Theses, TRIP Pro, and BASE. No language or date restrictions will be applied. Two independent reviewers will retrieve and review full-text studies and extract data. The results will be presented in tabular or diagrammatic format with a narrative summary.
