Key concepts and theoretical viewpoints related to green infrastructure, ageing and well-being from Group One disciplinary perspectives

Research specialism	Disciplinary concepts and principles relevant to the intersection of GI, ageing, health and well-being
Green Infrastructure	1. Multi-functionality (ecological, social and economic functions considered in parallel); 2. Physical and functional connectivity (linking people, habitats, function and species); 3. Social inclusion (societal needs are central to the planning process); 4. Trans-disciplinarity (drawing on knowledge from relevant disciplines and stakeholders) 5. A green infrastructure approach acknowledges the influence of scale in developing nature-based solutions to social-ecological challenges
Health	1. Rise of chronic conditions in the industrialized world (pathogenic model); 2. Integrated social-ecological models of health Individual health outcomes as the results of interacting biological, social and environmental factors;
Well-being	1. Subjective state theory/hedonism (feeling good): (after e.g. Epicurus; Jeremy Bentham), Well-being consists in having certain subjective psychological states 2. Preference satisfaction theory Well-being consists in the satisfaction of personal preferences, the stronger the preferences, the greater the well-being; 3. Objective list/state theory Well-being consists in the realisation or capacity to realise of certain objective goods or states such as particular forms of personal relation, physical health, autonomy, knowledge of the world, aesthetic experience, accomplishment and achievement, sensual pleasures, a well-constituted relation with the non-human world, and so on 4. Capabilities approach Well-being is defined in terms of in terms of capabilities to achieve central human functionings Functionings ‘the various things a person may value doing or being’—what people are able to be and do Capabilities ‘substantive freedoms to achieve alternative functioning combinations’ (Sen 1993 p.75)
Ageing	1. Acknowledgement of diversity within the ageing population; increase in demand for care with increasingly ageing populations; 2. There exists a need to address needs of black and minority ethnic group communities; 3. The central role of the neighbourhood in quality of life in older age; 4. Environmental volunteering may carry particular health benefits in later life 5. Co-research with older adult participants
Arts and Heritage	1. Cultural heritage Ways of living passed down through generations including Intangible Cultural Heritage such as oral traditions, performing arts, social practices, knowledge of the natural world, traditional craftsmanship 2. Safeguarding measures (e.g. as adopted by UNESCO) aim to promote and protect the viability of intangible cultural heritage, prioritizing opportunities for women’s empowerment 3. Creative practice as a method of participatory engagement
Value and valuation	1. Monetary valuation Assumes that monetary values can be assigned to features of the natural environment to facilitate their inclusion in market-based decisions, thereby highlighting their worth 2. Participatory methods of valuation (e.g. deliberative/democratic approaches): attempt to capture a range of values and perspectives hidden from monetary assessments
