The paper outlines the creation of a novel capsule by Green Moon Project (GMP) designed to meet essential criteria for monitoring and enhancing crop cultivation on the lunar terrain, tackling key obstacles such as self-propagation, fluctuating light patterns, water provision, and monitoring germination and growth stages. The Center of Space Exploration (hereafter COSE) managed to sprout the first seed on another celestial body during the Chang’e 4 mission on the Moon in January 2019. This achievement means an important step in space agriculture and widens the biological research of crops that will sustain future crewed missions and human bases in space. Space farming requires greater understanding if humans are to survive in space without constant contact from Earth and that is why GMP goals are aligned COSE’s. Therefore, GMP and COSE work in synergy to boost the research of space farming, future crops, habitability, and close controlled environmental systems. Due to the similarities between both projects, both teams decided to join efforts and cooperate in future space missions. To provide scientific support and technical solutions for future long-term crewed exploration missions, it is mandatory to conduct ground verification experiments of controllable extraterrestrial ecosystems.</p></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"16 ","pages":"Article 100160"},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666916124000136/pdfft?md5=5a94c0947452da427951eaa3da558572&pid=1-s2.0-S2666916124000136-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141026094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, the results demonstrate that the spatial spillover effect’s regional heterogeneity is positive in the eastern, central and northeastern regions, and negative in the weatern region. Furthermore, there is a spatial inhibitory effect on two subindustries of EII, i.e., Manufacture of Non-metallic Mineral Products industry and Smelting and Pressing of Non-ferrous Metals industry, proving the spatial spillover effect’s sectoral heterogeneity for green finance.

There are three findings: (1) The characteristics of DOM in SDI sediments, including content, hydrophilicity, molecular weight, and functional groups of aromatic rings, exhibited variation with land functional type; (2) Urban SDI DOM had low humification, and was primarily originated from autochthonous sources, with the proportion of humic-like components close to or exceeding 50%; and (3) SDI sediment DOM was likely to have different characteristics from road dust and stormwater due to microbial activities over dry season. Based on these findings, measures for urban stormwater infrastructure sustainability are proposed, including properly road sweeping, frequently SDI sediment dredging, decreasing in emission from industrial activities, promoting local educational practices, and limiting improper organic waste disposal.

Simultaneously, there are significant amounts of under-utilized​ rest raw materials (RRM) during harvesting, such as heads, skins, viscera, as well as prevalent food loss and waste (FLW) in the demersal fish supply chains. In this work we reviewed literature and conducted interviews with industry representatives to identify drivers and causes for FLW, as well as information on data capturing and current regulations in Norway and Iceland governing demersal fisheries. Based on these findings we have created a conceptual model of the demersal fish supply chain based on material and information flows modelling technique (MIFMT). The findings of our review indicates that losses during harvest and retail are the highest while the processing stage has the least volume of losses. However, there is currently no national level data generated on a regular basis which is identified as an important knowledge gap in mapping amounts of FLW. Our findings show that regulatory interventions during catch and improved RRM traceability could enhance the utilization of RRM in demersal fish supply chains. Information sharing and collaboration between the fishing fleet, seafood processors and the marine ingredient sector would allow improved resource utilization through better management of supply and demand. Furthermore, development of technology for on-board processing and storage is identified as a potential area of improvement.

In addition to considering the baseline scenario, considering the current livestock quantity (scenario C), we defined three strategies corresponding to livestock reduction scenarios: taking meat self-sufficiency as a priority regardless of the manure balance (scenario TB); taking manure N surplus avoidance as a priority regardless of the meat balance (scenario MNB); and considering the most limiting conditions between satisfying meat self-sufficiency and avoiding manure N surplus (scenario LF). A balance index was used to describe the excess (<em>i.e.</em>, positive value) or deficiency (<em>i.e.</em>, negative value) of meat and manure N.

City administrators currently lack a data-driven framework for allocating resources during constraint scenarios, leading to subjective decisions. Existing literature lacks objective solutions for managing city-scale green spaces, each with its distinct characteristics. Another challenge is handling varied spatial scales required for urban applications. This study proposes a novel goal programming-based model for urban green space management wherein multiple benefit objectives, such as conserving sequestered carbon in trees and enhancing quality and accessibility of parks, as well as handling demand constraints on available resources like water and personnel, are included. The proposed method was demonstrated in two cities with diverse conditions, Berlin and Melbourne, and evaluated on various benefit metrics, such as allocated green space units, resources consumed, and goals achieved. The model was analyzed with resource allocation decisions and goals at different spatial scales. The highest benefit achievement and resource allocation were observed when resources were allocated at the sub-district scale with a city-level target. Alternatively, setting targets at the district level provided a more even resource distribution; however, at the cost of reduced overall benefits. Results show that the proposed method increased the total benefits gained while effectively balancing conflicting goals and constraints. Additionally, it allows incorporating the city’s preferences and priorities, offering a scalable solution for informed decision-making in varied urban applications. Depending on data availability, this approach can be scaled to other cities, including additional benefits and resource constraints as required.</p></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"16 ","pages":"Article 100150"},"PeriodicalIF":0.0,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666916124000033/pdfft?md5=e3d058081785bd2c2942cea4e8fc1a33&pid=1-s2.0-S2666916124000033-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139718727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
