Boreal (Age)
In paleoclimatology of the Holocene, the Boreal was the first of the Blytt-Sernander sequence of north European climatic phases that were originally based on the study of Danish peat bogs, named for Axel Blytt and Rutger Sernander, who first established the sequence. In peat bog sediments, the Boreal is also recognized by its characteristic pollen zone. It was preceded by the Younger Dryas, the last cold snap of the Pleistocene, and followed by the Atlantic, a warmer and moister period than our most recent climate. The Boreal, transitional between the two periods, varied a great deal, at times having within it climates like today's.

Tailing Covering Technology for Oxidation Prevention
Water and oxygen are the main reactants to produce Acid mine drainage (AMD), and the inhibition methods should consider controlling the availability of one or two components. Therefore, two strategies are adopted: (i) preventing oxygen from entering the tailings pile and thus reducing the rate of sulfide oxidation; and (ii) isolating the infiltration of external water and thus weakening the role of dissolved oxygen. According to different coverage principles, tailing cover systems can be divided into dry covers, wet covers, and organic covers.

Metallic Iron for Environmental Remediation
Metallic iron (Fe0) used as a reactive material in subsurface permeable reactive barriers is comparable to iron pipes with three major differences: (i) corrosion is welcome because it is a rather useful process [7][8][9], (ii) a reactive wall is ideally permanently water saturated, and (iii) the length of used particles (< 5 cm) is tiny compared to pipes which are up to 12 m in length. On the one hand, Fe0 specimens used in water treatment comprise steel wool with thickness varying between 25 and 90 μm [10][11]. On the other hand, the length of these particles is comparable to the wall thickness of iron pipes (2–4 mm). There has been no real system analysis for remediation Fe0 materials with the aim to outline the differences making their peculiar characteristics. In addition, traceably deriving the longevity of remediation Fe0 specimens from Fe0 pipes is impossible because of the differences highlighted.

Weeds Enhance Pollinator Diversity in Mango
Weeds increase the diversity of pollinating insects on mango flowers, and mangos with weeds growing below produced more fruit than those without weeds. Weeds can provide ground cover and flowers that can support insect pollinators, natural enemies, and increase biodiversity at the field and landscape level.

Coastal Communities
Coastal communities are increasingly vulnerable to climate change and its effects may push coastal ecosystems to undergo irreversible changes. This is especially true for shorebirds with the loss of biodiversity and resource-rich habitats to rest, refuel, and breed. To protect these species, it is critical to conduct research related to nature-based Solutions (NbS).

Bioeconomy
Bieconomy is the economy of the green technologies and is capable to offer global food security, improve nutrition and health, create innovative bio-based products and biofuels. Bioeconomy would help agriculture, forestry, aquaculture, and other ecosystems to adapt to the climate change. It is an opportunity to boost innovation, create jobs in rural and industrial areas, reduce fossil fuel dependence, and improve economic and environmental sustainability.

Studies on Traditional Ecological Knowledge
Traditional ecological knowledge (TEK) dominated by traditional populations, especially fishermen and women, has been the object of scientific research from different perspectives, disseminating information on fauna and flora in different environments. Such interest refers to the importance that the set of information that these populations have on the dynamics of the local environment and the relationship with the environment in which they live. Generally, the transmission of this knowledge happens from generation to generation; however, it is still little valued by studies related to natural sciences. The study of this type of traditional ecological knowledge can support scientific studies and, therefore, help to fill the gaps in the understanding between the relationship between human activities and different ecosystems.

Recent Trends in Foliar Nanofertilizers
It is estimated that 40 to 70 per cent, 80 to 90 per cent and 50 to 90 per cent of the conventional macronutrients N, P and K applied to soil are lost, respectively, resulting in considerable resource losses. Compared with traditional fertilizers, nano fertilizers have small volume (1-100 nm) and high specific surface area, and have the advantages of controlled release, high nutrient utilization, low cost and relatively small environmental pollution. The application of nanofertilizers is an emerging area of agricultural research and is an attractive and economical alternative to traditional fertilizers that could sustainably increase global food productivity. Foliar fertilization is a popular method to meet the needs of higher plants. Due to the small amount of leaf application, nutrient absorption is faster than the soil, and environmental pollution is relatively small, so it is more popular in plants. It can be seen that nano-fertilizer and foliar fertilization are the focus of attention at present, and the study on the foliar application of nano-fertilizer is not as extensive as that of soil application.

Green Hydrogen in UK by 2030
Green hydrogen was first found in the UK by Robert Boyle in 1671 when he described ‘flammable air’. In 2022 Green hydrogen was prioritised by UK Government to replace fossil hydrogen and other carbon intensive fuels. Fossil hydrogen UK production then exceeded 1Mte/a, but this should fall significantly by 2030, overtaken by green hydrogen. The University of Birmingham revealed the first UK green hydrogen refueller in 2008 filling five hydrogen-fuel-cell-battery-electric-vehicles (HFCBEVs) for study and development by 50 PhD students in Chemical Engineering. This supplied 10 kg/day, much smaller than the 2021 ITM station now to deliver almost 600 kg/day at Tyseley.

Research Trends of Transformative Resilience
Transformational resilience is at the forefront of academic and policy initiatives on sustainable development, climate adaptation, and disaster risk reduction as a result of successive and complex changes in global dynamics. The concept has developed primarily around four key presentive domains: vulnerability and climate change adaptation, urban and regional disaster resilience, sustainability management and institutional transformation, and COVID-19. While priorities and subjects of research have evolved over time, key concepts such as resilience, adaptation, and climate change have recurred. Influential authors and documents from three interrelated resilience schools, including sustainable development, climate change adaptation, and disaster risk reduction, have shaped the field’s intellectual foundations.

Forest Fires on Air Quality in Wolgan Valley
Forests are an important natural resource and are instrumental in sustaining environmental sustainability. Burning biomass in forests results in greenhouse gas emissions, many of which are long-lived. Precise and consistent broad-scale monitoring of fire intensity is a valuable tool for analyzing climate and ecological changes related to fire. Remote sensing and geographic information systems provide an opportunity to improve current practice’s accuracy and performance.

Effect of PFAS Molecules for the Human Health
Per- and polyfluoroalkyl substances (PFAS) are a group of over 4700 heterogeneous compounds with amphipathic properties and exceptional stability to chemical and thermal degradation. The unique properties of PFAS compounds has been exploited for almost 60 years and has largely contributed to their wide applicability over a vast range of industrial, professional and non-professional uses. However, increasing evidence indicate that these compounds represent also a serious concern for both wildlife and human health as a result of their ubiquitous distribution, their extreme persistence and their bioaccumulative potential. In light of the adverse effects that have been already documented in biota and human populations or that might occur in absence of prompt interventions, the competent authorities in matter of health and environment protection, the industries as well as scientists are cooperating to identify the most appropriate regulatory measures, substitution plans and remediation technologies to mitigate PFAS impacts.

Towards Circular Economy for More Sustainable Apparel Consumption
The apparel industry causes environmental problems, particularly due to the shortening life cycle of garments and fast-fashion’s throw-away culture. The circular economy provides solutions to minimise and prevent these problems through innovative circular business models, which require changes in consumer behaviours. With the lens of environmental psychology, we analyse consumers’ willingness to acquire circular apparel considering four approaches on clothing life-cycle extension. We conducted an online questionnaire among Brazilian and Dutch consumers and tested if the Value-Belief-Norm (VBN) theory can explain the willingness of consumers to purchase circular apparel. Our results indicate that, overall, the variables from the VBN theory explain circular behaviour in the apparel industry and that the paths suggested by the model are supported by our analyses. Additionally, we tested and found that when all of the variables from the VBN theory were controlled for, materialistic values did not explain circular behaviours in the apparel industry among Brazilian respondents. However, they had a positive influence on some circular apparel behaviours among Dutch consumers. Overall, materialistic values did not play an important role in predicting willingness to consume circular clothing. Furthermore, the results suggest that the VBN theory predicts willingness to consume circular apparel better in the Netherlands compared to Brazil, suggesting that this behaviour may be perceived as more effortful for the Brazilian population. However, we highlight the need for future research.

Stir Casting Routes for Metal Matrix Syntactic Foams
Metal matrix syntactic foams (MMSFs) are advanced lightweight materials constituted by a metallic matrix and a dispersion of hollow and/or porous fillers. Physical and mechanical properties can be fitted regarding matrix and filler properties and processing parameters. Their properties make them potential materials for sectors where density is a limiting parameter, such as transport, marine, defense, aerospace, and engineering applications. MMSFs are mainly manufactured by powder metallurgy, infiltration, and stir casting techniques. Stir casting techniques (SCTs) are low-cost and industrially scalable approaches. Critical limitations of SCTs are buoyancy of fillers, corrosion of processing equipment, premature solidification of molten metal during mixing, cracking of fillers, heterogeneous distribution, and limited incorporation of fillers. Efforts to overcome these limitations have led to the development of new techniques and to obtain MMSFs with improved properties.
