Best Practices for Training in Sustainable Greenhouse Horticulture

Consumer demands and current legislation require intensive greenhouse horticulture to be sustainable. This poses the challenge of how to teach the concept of sustainable horticulture to all professionals involved in farming. The province of Almeria, in the south-east of Spain, is one of the major horticulture greenhouse areas in Europe, and an expert panel of relevant stakeholders was invited to look into the best pedagogical practices and methods to transfer technology and knowledge, with the goal of improving the sustainability of greenhouse horticulture. A combination of an online questionnaire, a Delphi method, and desk research was, therefore, used as the strategy to collect the data and implement the research design during 2021. On-farm/business demonstrations, virtual education, and classroom education were common pedagogical methods used. On-farm/business demonstrations, participatory education, and co-learning were identified as the best pedagogical methods to use in sustainable agriculture/horticulture training. The expert panel also concluded that participatory education and co-learning should be further explored whereas virtual and classroom education should play a less dominant role in the training activities. This knowledge can help training organizations and designers to avoid common mistakes, tailor their training activities, and be mindful of common barriers and (mis)conceptions. © 2023 by the authors.

Toward Regenerative Sustainability: A Passive Design Comfort Assessment Method of Indoor Environment

The fact that people spend a major part of their lifetime indoors, together with the lethal COVID-19 pandemic which caused people to spend even more time inside buildings, has drawn attention to the significance of achieving Agenda 2030 SD goal number three: good health and well-being, in reference to the indoor environment. The research subject is the health and well-being of building users explored through the sustainable (passive) design principles having an impact on the comfort and quality of the indoor environment. It is set within a regenerative sustainability framework encompassing the physiological, biophilic, psychological and social aspects of comfort. The Comfort Assessment Model's categories, to some extent, rely on the first author's doctoral thesis, with further modifications regarding the passive design criteria and indicators. A comparative analysis of the model with international sustainability certification (rating) systems has been performed, proving the significance of introducing more passive design comfort (health) related criteria into sustainability assessment models. In addition, a focus group of expert architects contributed to the research conclusions by responding to a questionnaire addressing the issues of sustainability, comfort and passive design, in terms of the health and well-being of building users, which confirmed the relevance of applied passive design measures for providing comfort indoors and fulfilling sustainable development goals. © 2023 by the authors.

‘What we'd like is a CSA in every town.’ Scaling community supported agriculture across the UK

As the Covid-19 pandemic exposes the vulnerabilities of our globalised agri-food system, local sustainable food alternatives, such as community-supported agriculture (CSA), are on the rise. In CSA local farmers and households co-produce food sustainably and independently of the market. CSA's benefits and shortcomings are well-understood but we know little about how larger CSA networks can expand and consolidate the practice at scale. This paper investigates the UK CSA network, showing its ability to upscale, outscale and downscale CSA through institutionalisation, replication and politicization, before discussing the network's strategic limitations and dependencies. © 2022 The Author
