Tudo o que comemos gera impactos ambientais: do uso do solo na lavoura, passando pelo transporte, processamento, consumo e descarte de embalagens e resíduos. Entender esse impacto ambiental da alimentação é complexo, mas já existem informações suficientes para orientar decisões mais bem informadas.
Objective: Childhood stunting is a significant health issue in Rwanda, particularly within the Northern Province. While demographic and socio-economic factors have been more extensively studied, the impact of environmental and climatic factors on stunting prevalence has received less attention. This study aimed to determine if these factors could be used to better predict localized variations in h
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ-diversity), either due to reduced β-diversity amplifying diversity loss or increased β-diversity dampening diversity loss. Additionall
Anthropogenic land-use and climate change pose novel selection pressures on bees, yet their evolutionary responses in terms of morphological or physiological adaptations remain unclear. While adaptive responses are expected, these may be constrained by gene flow when changes in selection pressures are spatially heterogeneous. The buff-tailed bumblebee (Bombus terrestris) is a widespread species th
Residential gardens can provide pollinator habitat and thus contribute to mitigating declines of insect pollinators. To further improve gardens for pollinators, it is necessary to understand the factors and pathways leading to successful conservation interventions. We studied how the success of two common pro-pollinator interventions, garden meadows and flower plantings, were influenced by gardene
Under 1680-talet trädde Sophia Elisabet Brenner fram som poet och blev snart känd och uppskattad för sina dikter vid olika tillfällen i livet. Tillfällesdiktningen var en flexibel genre som gav henne möjligheten att resonera om tidens aktuella frågor, till exempel kvinnans ställning i äktenskap och samhälle eller värderingen av det som var gammalt och fornt och det som var nytt. Hennes rykte spred
Access to a quiet side in one's dwelling is thought to compensate for higher noise levels at the most exposed façade. It has also been indicated that noise from combined traffic sources causes more noise annoyance than equal average levels from either road traffic or railway noise separately.
Economic contacts between countries have steadily increased over the years. This in part reflects the rapid growth of international economy and the increased investment in several countries. These international business activities have led to the formation of a group of company conducting business activities in two or more countries, which is known as MNEs or multinational enterprises. Nowadays
Riverine colloids are important carriers of macronutrients, trace metals, and pollutants into marine waters. The aim of the current study was to extend the understanding of iron (Fe) and organic carbon (OC) colloids in boreal rivers and their fate at higher salinities. X-ray absorbance spectroscopy (XAS) and dynamic light scattering (DLS) were combined to explore Fe speciation and colloidal charac
Just nu finns det en möjlighet för politikerna att lägga om stadsplaneringen så att det blir möjligt att nå FN:s hållbarhetsmål. Det skriver åtta forskare som arbetar med miljö- och hälsofrågor.

The main purpose of this study was to establish to what extent undergraduate students use reference services, what knowledge they have about those services and what their views of them are. The survey took place at Lund University Library, UB1, the main library responsible for collections in social sciences, humanities, theology and law. A total of 476 undergraduate students were asked to fill in
Uncertainty refers to any limitation in knowledge. Identifying and characterizing uncertainty in conclusions is important to ensure transparency and avoid over or under confidence in scientific assessments. Quantitative expressions of uncertainty are less ambiguous compared to uncertainty expressed qualitatively, or not at all. Subjective probability is an example of a quantitative expression of e
The ongoing wide-scale introduction of nonnative plants across the world may negatively influence native invertebrate fauna, due to a lack of coevolved traits related to the novel plants, e.g., unique phytochemicals or shifted phenology. Nonnative plants, specifically trees, are common in urban environments, areas that already pose novel habitats to plants and wildlife through a wide array of anth
Fatty acid biomarkers have emerged as a useful tool to quantify biomass of various microbial groups. Here we focus on the frequent use of the fatty acid 16:1ω5 as a biomarker for arbuscular mycorrhizal (AM) fungi in soils. We highlight some issues with current applications of this method and use several examples from the literature to show that the phospholipid fatty acid (PLFA) 16:1ω5 can occur i
Green infrastructure (GI) is increasingly used in policymaking to promote biodiversity and enhance ecosystem services through the protection, creation, restoration and connection of natural and man-made green areas. The EU Commission adopted in 2013, the concept as a strategy. When member states apply the policy, it is translated into specific bureaucratic and political systems, creating different
Site-specific land management practice taking into account variability in maize yield gaps (the difference between yields in the 90th percentiles and other yields on smallholder farmers’ fields) could improve resource use efficiency and enhance yields. However, the applicability of the practice is constrained by inability to identify patterns of resource utilization to target application of resour
