The findings suggest that merely increasing ESs supply is not the primary objective of the local spatial management, addressing key trade-offs among ESs should take precedence. For instance, promoting sustainable agriculture can mitigate conflicts between ESs, reduce boundaries between woodland and cropland, foster synergies among multiple ESs, and alleviate the imbalance in ecological development between the northern and southern regions. In highly urbanized areas, the growth of urban green spaces can also contribute positively to sustainable development.

Evaluating the spatiotemporal dynamics of global titanium trade patterns is essential for a comprehensive understanding of the titanium trade situation and for enhancing the stability of the titanium supply chain. To this end, this paper constructs global trade networks of titanium ore, titanium dioxide, titanium sponge, and titanium products and utilizes various network analysis methods to deeply investigate the spatiotemporal evolution of global titanium trade patterns, the topology of the trade network, and the resilience characteristics. The study reveals a growing global titanium trade with fluctuations, significantly clustered trade flows, and expanding, denser networks with optimized structures. Over the past 20 years, the trade volumes of titanium ore, titanium dioxide, and titanium products have increased to approximately 2.93, 1.80, and 1.90 times their previous levels, respectively. The global titanium trade networks present significant core–periphery structure characteristics. The centralization coefficients of the four types of titanium commodity trade networks all exceed 0.9, with clear boundaries between the core and peripheral layers, as well as differences in connectivity across the various layers of these networks. The resilience of the global titanium trade network has increased over time, with the resilience of the titanium dioxide and titanium products trade networks significantly higher than that of titanium ore and titanium sponge. However, the failure of key nodes such as China, the United States, and Germany still has a greater impact on network connectivity, and the overall ability of the network to resist intentional attacks is still limited. Finally, this paper puts forward policy recommendations to promote titanium trade cooperation, enhance the resilience of the titanium trade network, and maintain the security of the titanium supply.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"20 ","pages":"Article 100213"},"PeriodicalIF":12.4,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549529","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}

Breeding programmes have significantly increased the availability of early-, mid-, and late-maturing crop cultivars tailored to the Target Population of Environments in Sub-Saharan Africa. However, there is a substantial lack of data-driven maturity group recommendations at a detailed spatial scale. The absence of targeted guidance on the suitability of maturity groups limits the ability of smallholder farmers to make optimal cultivar adoption decisions. Here, we propose a framework using gridded crop modelling to identify locally relevant maturity group recommendations at a high spatial resolution for field crops. Implementing the framework for maize in Ghana, we employ the APSIM crop model across 3927 point locations and weather records for recent thirty years. We show that mid-maturing cultivars consistently provide the highest yields across all national production locations in the major growing season. In the minor growing season, we find that early- and mid-maturing cultivars provide the highest yields across distinct spatial suitability clusters. Specifically, in the minor growing season, mid-maturing cultivars provide the highest yields in high-yielding environments, while early-maturing varieties provide the highest yields in low-yielding environments. We identify specific environment-by-management combinations for which different maturity groups are optimal. The proposed framework enables the development of spatially and seasonally tailored maturity group recommendations that take advantage of prevailing genotype-by-environment-by-management interactions.

Accordingly, the application of pLCA is rapidly growing in recent years, with emerging methods addressing the limitations, and improving pLCA. This review study aims to compile and analyze emerging pLCA methods from scientific literature, identifying best practices and limitations to guide future research. It discusses methodological advancements in pLCA, including prospective life cycle inventory (pLCI) database, foreground modeling, scenario development and prospective life cycle impact assessment, offering insights for practitioners. While changes in background systems are increasingly addressed in pLCA studies, some, particularly earlier or less systematic ones, fall short of fully integrating nuanced future scenarios. The reviewed studies highlight that incorporating future scenarios related to the transformation of energy, material, transport, and industrial systems can significantly influence LCA outcomes, reinforcing the importance of explicitly integrating such scenarios into pLCA to ensure reliable and meaningful results. To ensure robust LCA studies, it is important to consider the use of pLCI databases, accounting for varying technology maturity levels, their improvement and diffusion rate, and incorporating spatial considerations. Yet, integrating pLCI databases with standard LCA tools remains complex, with a lack of practitioner guidance. Moreover, the interlinkage between climate change and various impact categories is a key source of uncertainty in future assessments, highlighting the need to improve both prospective inventory modeling and impact assessment.

Consequential life cycle assessment (LCA) evaluates environmental sustainability, often identifying “hidden” impacts incurred through market displacements. However, it is often impractical to screen multiple bioeconomy feedstocks and value chains using full consequential LCA early in project conceptualisation, owing to high requirements in terms of time, data, and expertise. As a result, critical environmental risks may not be discovered until too late in project development to redirect investment towards more sustainable options. This paper introduces the Bio-based feedstock Environmental Risk Assessment (Bio-ERA) Framework, designed to support early screening of potential upstream environmental risks associated with increased demand for bio-based feedstocks. The Bio-ERA Framework comprises a decision tree that systematically guides stakeholders through consequential life cycle thinking, elucidating sometimes hidden (indirect) pathways of impact among feedstock sourcing decisions. Seven important environmental aspects are addressed: Finite Resource Inputs, Greenhouse Gas (GHG) Emissions, Air Quality, Water Quality, Ecosystem Diversity, Terrestrial Carbon Storage, and Indirect Land Use Change. Criteria are proposed to structure evaluation of (i) probability and (ii) severity of environmental impact, in relation to four categories of feedstock: primary (determining product), high-value by-product, low-value by-product, and waste. Example applications demonstrate how the framework can generate an environmental risk profile for specific feedstocks sourced in specific contexts. Bio-ERA does not avoid the need for detailed LCA evaluation of full bioeconomy value chains, but promotes deeper interrogation and awareness of potential environmental risks associated with feedstock sourcing, in a manner that is accessible to all stakeholders. This could support <u>earlier</u> screening of strategic investment decisions necessary to develop a sustainable bioeconomy.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"20 ","pages":"Article 100201"},"PeriodicalIF":12.4,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480224","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}
