Our well-being includes our quality of life, our prosperity, our physical and mental health and the communities around us. The main purpose of the planning system in Wales is to ensure sustainable development, making sure that current needs are met but not at the cost of future generations to meet their own needs. Public Health Wales has set out long term priorities for health including how we will improve people’s well-being and reduce inequalities in health. One way to help achieve this is through us working with partners such as land use planners and policy makers.
