“…In a circular economy, resources are used, reused, and redeveloped in a closed loop, rather than being extracted, used, and abandoned as waste. In order to enhance the current response to the global climate crisis, Romero-Perdomo et al (2022) propose the circular economy (CE) as a potentially significant facilitator. The author examines the scientific literature on the research between climate change and CE adopting a knowledge mapping approach.…”

Climate change heightens global warming and brings about impending risks for both human society and natural systems. Climate change is the greatest threat modern humans have ever faced. Pollutant discharges involve the global atmosphere and result in the challenge of global warming that must be solved before it results in irreversible damage. Current common threats of crises need common actions among all of us: every continent, every country, every community, and every common citizen. The earlier an action, the larger its impact. This review article scrutinizes the newest developments in this paramount important research area and provides directions for future research.

“…As the keyword "greenhouse" can be used in the context of both protected agriculture and climate change, it was necessary to use a fourth parenthesis to avoid retrieving off-topic posts (e.g., "greenhouse effect") using the Boolean operator "AND NOT". The truncation symbol (*) was also used to find both singular and plural words, and the proximity operator (" ") was used to find an exact sentence [20]. The defined search query is shown in Table 1.…”

Researchers and practitioners use life cycle assessment (LCA) as a powerful tool to thoroughly assess the environmental impact of protected agriculture. However, the literature in this field has shown heterogeneity, which is characterized by inconsistent methodologies and assumptions. Identifying prevailing trends and resolving existing limitations is necessary to generate robust results and guide future work. Here, we conduct a bibliometric and systematic review to explore how LCA applications have addressed protected agriculture. The bibliometric analysis unveils trends in scientific productivity, spanning temporal evolution and geographic distribution, while also identifying prominent research avenues. The systematic review traces the historical trajectory of agricultural LCA and scrutinizes methodological decisions across the standard LCA phases: (i) objective and scope, (ii) life cycle inventory, (iii) impact assessment, and (iv) interpretation. We summarize and discuss the reported environmentally friendly practices and provide a qualitative interpretation of the LCA findings. Moreover, we pinpoint key methodological challenges and propose research horizons. It is crucial to note that the environmental benefits of protected agriculture are context-dependent, with climate change emerging as a critical factor influencing crop yields and the system’s input and output resources. This impact is particularly pronounced in terms of water and energy consumption and carbon emissions. In regions with extreme climates, protected agriculture provides solutions for producers aiming to attain high yields of top-quality crops. The integration of circular bioeconomy strategies in this context allows mitigation of the environmental trade-offs identified by LCA.

“…Circular research on energy resources has shown progress in substituting fossil fuels for bioenergy sources to improve the microclimatic management of greenhouses and thus reduce greenhouse gases [55]. This need has drawn attention to the identification that the processes that maintain optimal conditions for plant growth, such as cooling, heating, humidifying, and adding light, emit 96% of the greenhouse gases produced in protected horticulture models [56].…”

The integration of the circular economy in agriculture has promoted sustainable innovation in food production systems such as horticulture. The present paper illustrates how horticulture is transitioning to the circular economy. This research field’s performance approaches and trends were assessed through a bibliometric and text-mining analysis of the literature. Our findings revealed that circular horticulture is a recent research field that is constantly growing. Its approach has been neither systemic nor integrative but fragmented. Bioeconomy, urban agriculture, recycled nutrients, biochar, fertigation, and desalination have been positioned as research hotspots. Vegetables and fruits are the most studied crops. Resource circulation has focused primarily on biowaste recovery to provide benefits such as biofertilizers and linear-substrate substitutes, and on water reuse for the establishment of hydroponic systems. The One Health approach is scarcely explored and, therefore, weakly articulated, wherein the absence of assessment methodologies encompassing the health of ecosystems, animals, and people is a notable limitation. Science-policy interfaces between One Health and food systems need to be improved. Lastly, greenhouse technologies are aligned with bioenergy, sustainable materials, and sensing technologies. Challenges and directions for future research have been raised to promote the redesign of horticultural production systems, integrating long-term circularity.
