Salinization is a major cause of soil degradation that affects several million hectares of agricultural land, threatening food security and the sustainability of agricultural systems worldwide. Nevertheless, despite the negative impact of salinity, salt-affected land also provides several important ecosystem services, from providing habitats and nurseries for numerous species to sustainable food production. This opinion paper, written in the framework of the EU COST Action CA22144 SUSTAIN on the sustainable use of salt-affected land, therefore, focuses on the potential of halophytes and saline agriculture to transform and restore key functions of these salt-affected and marginal lands. As the current knowledge on sustainable saline agriculture upscaling is fragmented, we highlight (i) the research gaps in halophyte and salinity research and (ii) the main barriers and potentials of saline agriculture for addressing food security and environmental sustainability in terms of population growth and climate change.

This study explores the relationship between climate change awareness (CCA) and consumers’ willingness to pay (WTP) for urban short food chains (USFC), focusing on the mediating role of biospheric, egoistic, and altruistic environmental concerns. A structured questionnaire was conducted with 230 respondents in Tirana, Albania, and the results were analysed using the PROCESS macro in SPSS 25.0. The findings reveal that CCA increases all three environmental concerns; however, only the altruistic concern significantly mediates USFC participation, particularly by limiting food waste (effect size = 0.502, p = 0.002). In contrast, egoistic concern negatively affects WTP, highlighting a value–action gap in sustainable behaviour. Reducing ultra-processed food consumption emerges as a key driver of engagement, linking personal and environmental health to local food choices. Gender moderates these relationships; despite showing high ecological concern, women express lower WTP due to household and budgetary considerations. Supporting the model, the survey data show that 88% of respondents are willing to pay a premium, typically 10–20% more, for food products from their preferred origin, and 88% are also willing to participate in the Tirana USFC initiative. The highest WTP (30%) is reported among highly educated women with children aged three to five. These findings highlight the need for targeted urban food policies that account for sustainability’s psychological and demographic dimensions.

This study explores the relationship between Climate Change Awareness and consumer willingness to pay for Urban Short Food Chains, focusing on the mediating role of biospheric, egoistic, and altruistic concerns. Whether driven by egoistic or altruistic motivations, the reduction of ultra-processed food consumption emerges as a key factor in consumers' willingness to pay a premium for products from urban short-food chains (USFC). The studies also show that urban residents often maintain a strong connection to the food traditions and products of their native regions, even after relocating to cities. This connection influences their food preferences and purchasing decisions, effectively bringing their "territory" with them to urban settings. This dynamic underscores the importance of promoting local, minimally processed foods, which align with these traditional preferences, while also addressing the broader environmental and social impacts of industrialised food production. By fostering these connections, urban food systems can become more sustainable, balancing cultural heritage with modern dietary needs.
