Titanium is a crucial raw material in the chemical industry, metallurgy, machinery manufacturing, aerospace, and other fields. 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.

We design an eco-scheme under the framework of the Common Agricultural Policy (CAP) 2023–2027 integrating the two most relevant agricultural practices for pollinator conservation: setting aside conservation land areas and reducing pesticides. Our main objectives are: (i) to measure farmers’ willingness to accept the implementation of pollinators-friendly agricultural practices, and (ii) to assess the effect of farmers’ environmental concerns and the source of recommendation on said willingness. A choice experiment is used to measure farmers’ preference for alternative designs of the eco-scheme in two cropping systems representative of the Aragonese and Mediterranean agriculture: rainfed extensive crops and irrigated/permanent crops.

As we find, Aragonese farmers are willing to uptake agricultural practices for pollinator conservation to certain extent if they are paid to do so. This is especially true for setting aside land for conservation where more demanding practices could be accepted within current Spanish unitary payments (per ha payment). The reduction or elimination of pesticides would require payments far beyond current Spanish unitary payments. Irrigated/permanent crop farmers require larger payments than rainfed crop farmers. Farmers with pro-environmental attitudes selected more environmentally-demanding alternative levels both for sparing agricultural land and reducing pesticides. Finally, the uptake of the eco-scheme could be easier if cooperatives play an active role in its promotion. The hypothetical eco-scheme presented here could be readily implemented within CAP eco-schemes while integrating the objectives of the European Pollinators Initiative, the Biodiversity Strategy 2030 and the Farm to Fork Strategy.

Ensuring urban food security while reducing carbon emissions from food systems is a key challenge. Food localization can reduce transport emissions; however, its role in agricultural production emissions reductions is unclear. Here, we explored the effects of localization of seven perishables, incorporating emissions from production and cold-chain logistics, in Beijing and Shanghai, China; determined decarbonization under different scenarios by increasing or decreasing the localization, with or without constrains, of each food category (balancing strategy). The results show that every 1% increase in the localization of vegetables, poultry, and aquatic products decreased 2020 emissions by 0.4–1.9 tCO₂e, but for beef and lamb, it increased emissions by 0.2–2.9 tCO₂e. Localization decreased cold-chain emission shares for all foods. The balancing strategy with constraints reduced emissions by

\sim

0.76 MtCO₂e (5%) and

\sim

0.44 MtCO₂e (2%) in 2020 in Beijing and Shanghai, respectively. Utilizing urban agriculture at all costs (i.e., without constraints) further reduced emissions by a factor of 3–4. Over 90% of Beijing’s emissions added by 2035 under the business-as-usual scenario were projected to be offset by the strategy. In Shanghai, the strategy could reduce emissions by an additional 0.44 MtCO₂e. The results indicate that expanding imports of carbon-intensive ruminant meat to replace local production and reallocating urban resources to vegetables, poultry, and aquatic products could lead to more sustainable food supplies in megacities. Further development of cold-chain logistics is expected to reduce emissions in synergy with the balancing strategy. Our results could help inform better food system planning in megacities.

The adoption of suitable crop cultivars is central to the sustainable intensification of smallholder cropping systems across Sub-Saharan Africa and plays a crucial role in improving smallholder incomes and food security. 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. The approach can readily be scaled to other crops and countries.

To enhance the quality of forage-grain ratoon rice (FGR) and promote the sustainable development of both rice and livestock industries in southern China, this study investigates the microbial fermentation dynamics of co-ensiling FGR with maize or sorghum-sudangrass hybrid. Results demonstrate that co-ensiling with maize significantly improved fermentation quality, reducing fiber content and enhancing lactic acid production, compared with sorghum-sudangrass hybrid. The optimal FGR-to-maize ratio of 75:25 yielded the lowest neutral detergent fiber and acid detergent fiber values and the highest lactic acid concentration (39.37 g/kg DM). Co-ensiling promoted the growth of beneficial lactic acid bacteria (LAB), particularly Lactobacillaceae and Sporolactobacillaceae, thus enhancing fermentation efficiency. Additionally, inoculation with Lactobacillus plantarum improved silage stability by promoting LAB growth and inhibiting the growth of undesirable Enterobacter species. This study offers a sustainable strategy to optimize rice straw utilization for livestock feed, reduce dependence on imported forages, and support agricultural sustainability in China.

Prospective Life Cycle Assessment (pLCA) is gaining interest due to its inherent future-oriented feature, which is an essential component of every decision-oriented life cycle assessment. Previous studies have highlighted challenges in conducting pLCA for emerging technologies, categorizing them into issues of comparability, data availability, scaling, and uncertainty and propose general frameworks to address these challenges. 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. The findings call for future research to further explore the spatiotemporal effect of climate change on pLCA quantification, developing future-oriented characterization factors, expanding pLCI databases, as well as enhancing the applicability of pLCA studies through the integration of new analytical tools and models.

A life cycle thinking-based environmental risk framework for screening sustainable feedstocks in early-stage bioeconomy projects

Understanding the environmental impacts of bio-based feedstock production is essential for sustainable bioeconomy development. 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 earlier screening of strategic investment decisions necessary to develop a sustainable bioeconomy.

The assessment of ecosystem service losses is crucial for ecological impact assessment and the practice of ecological compensation restoration projects. However, few studies on assessing losses have focused on ecosystem services, and the existing knowledge is fragmented. This review synthesizes the research status, methods, and key findings in the field. It outlines the research status by categorizing studies into human, natural and comprehensive disturbance assessments by disturbance events. A basic framework for future research is established by summarizing assessment procedures and methods. Comparisons of the magnitude of losses and analyses of driving factors in existing studies have been discussed, and recommendations for future research directions have been proposed. Research indicates that since 2010, studies related to this topic have gradually increased, with a predominant focus on the losses caused by human disturbance. Regulatory services are the most frequently assessed type. Most results suggest that the magnitude of losses varies across different types of ecosystem services, ecosystems, and stages of ecosystem degradation. The regularity of these losses remains to be explored. Land use and climate change are two major driving factors, and distinguishing between their impacts is crucial. Therefore, future research should enhance assessments at multiple scales, promote more accurate assessments from aspects of data acquisition and evaluation methods, and deepen the exploration of loss regularity and drivers. This review fills the gap in systematic understanding of ecosystem service losses, offering a comprehensive reference for further research and the establishment of standards for ecological restoration and compensation.

Existing methods for resource nexus analysis do not cover all aspects of complex resource management problems. Key methodological challenges include setting the scale, scope, and resolution of a nexus analysis, as well as adequately representing the quantity and quality of resource interactions. Additionally, determining the degree of collaborative governance for resource management, accounting for the role of existing policies, and developing robust scenarios for future predictions are also crucial constraints. To address these limitations, we developed a conceptual model of the resources nexus for Otta valley in Norway, an area characterized by resource use trade-offs across interconnected systems. We introduced the concept of “resource scapes” which is the physical availability, key interactions, management networks, and policies governing a resource at a specific time and place. We defined resource scapes for water, energy, and biomass resources in the studied area. Employing stock and flow loops, social network analysis, material flow accounting, and policy reviews, we developed the model in a layered topology using the coupled component modeling approach. In addition, we developed future resource scenarios nested within national pathways – the Norwegian nexus pathways (NNPs) – aligned with the five globally adopted shared-socioeconomic pathways (SSPs), using a narrative downscaling approach. Our results show that annual variations in resource balances are connected to changing externalities. A low Network External-Internal (EI) index (0.392) indicates weak overall collaborative governance of nexus resources. Our modeling framework (1) addresses limitations in current nexus methods, (2) facilitates testing of alternative policy interventions under future scenarios, and (3) provides a framework for development of integrated assessment models. This approach merges the concept of nexus governance with integrated assessment modeling, thereby enhancing the application of nexus approach for efficient resource management which will be crucial in future as climate and socioeconomic conditions evolve.
