Bridging biodiversity and gardening: Unravelling the interplay of socio-demographic factors, garden practices, and garden characteristics

Abstract

The expansion of urban areas threatens biodiversity and disrupts ecological relationships, thereby impeding key ecosystem services. To avert irreversible consequences, there is a focus on improving the biodiversity value of domestic gardens. We employ machine learning and network analysis and examine gardening practices and garden owners’ environmental consciousness in Hungary through a questionnaire-based study to untangle the interplay among socio-demographic factors, garden management and -characteristics. We found that the activities determined as biodiversity-positive were widespread among respondents, but ubiquitous pesticide use (62.14%), lack of undisturbed areas (49.52%), and frequent mowing (32.06%) were also present. Middle-aged respondents demonstrated more biodiversity-supporting activities than those over 55, who had long-term gardening experience and were predominantly conventional gardeners. Respondents of towns showed the least biodiversity-positive activities, whereas those living in cities and the countryside fared better. Additionally, multiple interconnected garden characteristics revealed various types of gardens distinguished by care practices and use, such as gardens for food self-provisioning, ornamental gardens, or those prioritizing biodiversity support. Our results show that garden owners use pesticides independently of socio-demographic parameters, gardening practices, or garden characteristics, suggesting widespread pesticide use in Hungary. Our findings suggest that strategies to promote biodiversity-friendly gardening may not be equally suitable for all gardener owners with different cultural backgrounds, environmental consciousness and gardening habits. Factors like differences between societal groups underscore the preference for in-person programs over online information transfer in several cases, for instance, among the elderly and those living in the countryside. We offer fresh perspectives on the intricate connections between garden diversity, characteristics, and practices, and it lays the groundwork for future research into the sociological drivers of gardening practices in Eastern Europe. Our work emphasises that optimizing gardens for multiple ecosystem services, including biodiversity conservation and enhancing human well-being, requires a nuanced understanding of both ecological and socio-demographic factors.
