Rethinking Horticulture to Meet Sustainable Development Goals—The Case Study of Novi Sad, Serbia

Abstract

With the aim of being a part of global change and providing an example to other researchers throughout the world, this paper details how breeding goals of horticultural plants and their application have shifted in Novi Sad (Serbia) in the last 10–15 years. Contemporary cities/citizens strive to incorporate nature into all of their important life segments and activities, thus requiring an interdisciplinary approach to solving challenges that the 21st century brings. Early research in Novi Sad (Serbia) was focused on the basic genetic, physiological, biochemical and botanical aspects of plant functioning and development in a challenging and changing urban environment abundant in abiotic stressors, as well as biotic and abiotic stressors, that affect the production of horticultural plant in this field. Recently, research interest has shifted towards the sustainable usage of plant genetic resources (roses, autochthonous terrestrial orchids, sweet and sour cherry eco-types, and allochthonous oil-rich species), as well as sustainable practices and nature-based solutions (urban-derived biodiesel, rain gardens, green roofs, green walls, constructed wetlands, water ponds, bioswales and permeable surfaces on a different scale of urban planning). This case study aimed to illustrate how plant selection and breeding strategies can satisfy urban growth demands, whereas urban planning must include sustainable genetic resources suitable for urban ecosystems. Available ornamental plant genetic resources (with pronounced tolerance/resistance to abiotic and/or biotic stressors) associated with the novel approach of their application in green city infrastructure provide the opportunity to implement multiple nature-based solutions leading to numerous ecosystem services. Combined, these contribute to the globally defined goals for sustainable development.
