Climate-smart agriculture (CSA) is an evolving approach to balance heightened crop productivity, reduced GHG emissions, and enhanced resource adaptability to climate change. A comprehensive model was developed to facilitate the sustainable and coordinated development of land, energy, food, and waste nexus systems. This study seeks to tackle the pressing necessity by incorporating advanced modeling techniques to enhance resource allocation and decision-making in agricultural systems, aiming for a triple win in reducing GHG emissions, enhancing food security, and promoting economic sustainability. An integrated approach harnessing life cycle assessment, system dynamics model, and multi-objective optimization methodologies was employed to evaluate the effects, trade-offs, and synergies of resource allocation in the context of CSA practices. In Jiangxi Province, China, a case study demonstrated notable reductions in overall carbon footprints, ranging from 6.02 % to 12.03 %. Additionally, applying the Non-dominated Sorting Genetic Algorithm II optimization algorithm to the model led to significant enhancements, such as an 11.24 % increase in grain nutrient availability, a 20.99 % boost in economic returns, and a 19.36 % decrease in GHG emissions. The findings underscore the efficacy of optimizing resource allocation to attain economic, environmental, and social advantages and curb carbon emissions. Moreover, pivotal policy recommendations encompass land use transformation, optimal food production allocation, and bioenergy production restructuring. Enforcing the practices of CSA and integrating them with carbon market transactions are crucial for sustainable agricultural development. This innovative framework provides a sustainable global agricultural management model with a low-carbon footprint, which is particularly beneficial in resource-scarce regions with competing policy objectives.</p></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"50 ","pages":"Pages 536-555"},"PeriodicalIF":10.9,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We further derive ten key findings and 36 requirements for a framework for the engineering of BMfS.

Modelling circular economy strategies in the Life Cycle Assessment (LCA) of EV batteries comes with a number of key challenges to ensure sound support to decision-making, including i) solving multifunctionality, whether regarding End-of-Life, processes of secondary raw materials production or product level, ii) capturing material quality aspects and iii) using adequate resource indicators. This study provides a review of LCA guidelines and scientific literature relative to EV batteries. The objective is two-fold: i) identifying key gaps in the guidelines regarding these modelling challenges, and ii) discussing how to fill them based on the state-of-the-art research. The analysis shows that the handling of multifunctionality is addressed in all analysed guidelines but is treated very differently. Major efforts are expected in terms of standardisation and harmonisation, building on the existing state-of-the-art research. A guiding question for standardisation is whether multifunctionality shall be always treated in the same way or whether special rules are appropriate. Instead, material quality and indicators of mineral resource losses are not at all, or to a very limited extent, addressed by existing guidelines. For material quality and mineral resource dissipation and accessibility-based indicators, research developments shall be pursued. Associated research outcomes are ultimately expected to be fed back into the guideline development in a more mid to long-term. The approach for handling these modelling challenges could and should be consistent between different products and sectors of the energy and mobility transition, to avoid double counting and burden shifting.</p></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"50 ","pages":"Pages 556-570"},"PeriodicalIF":10.9,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352550924002586/pdfft?md5=a3210cf191d723f83c8805e524091a11&pid=1-s2.0-S2352550924002586-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its widespread adoption requires knowledge of its implications at the different levels of the urban water cycle. This paper aims to provide a holistic overview and global understanding of the opportunities, challenges and implications associated with the widespread adoption of water conservation measures on the urban water cycle. A systematic search was conducted to identify water conservation case studies within the municipal sector. The analysis of studies' results highlighted that water conservation can significantly reduce buildings' water use while also providing energy savings in both buildings and water utilities. Water conservation measures were found to be economically feasible in most cases, with relatively short payback periods, although conclusions were more nuanced when adopting alternative water sources. This suggests that water conservation measures may be a better option than supply-side solutions to maintain water supply in cities. However, their performance may be undermined by design problems or user behaviour. Therefore, education and communication are key drivers for their widespread adoption. Lower water demand resulting from the implementation of conservation measures may reduce the need for water systems upgrades, delaying major investments, but this may also adversely impact these systems, causing water quality issues in distribution networks, degrading the hydraulic performances of sewers, and altering wastewater treatment efficiencies. The widespread deployment of water conservation measures requires technical, financial, social, and political considerations. Further research is still required to better understand its implications for water systems, assess its impact on water and energy use, and support decision-makers in developing water conservation programmes.</p></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"50 ","pages":"Pages 571-586"},"PeriodicalIF":10.9,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352550924002525/pdfft?md5=1aeb0132ca9a6b93c351fda50eb5c93e&pid=1-s2.0-S2352550924002525-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of 30,000 Monte Carlo simulations performed on 26 input variables, it was found that the key parameters in final disposal and resource consumption potential differ between the two purposes; avoiding catastrophic loads and achieving ambitious reductions. In contrast, for greenhouse gas emissions, it is important to maintain or increase the efficiency of photovoltaic panel power generation for both purposes. Additionally, in the case where the key variables were optimized in terms of final disposal/resource consumption potential, it will effectively reduce the two impacts to 0.7 % and 12.6 %, respectively, with a minimal negative impact on greenhouse gas emissions.
