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
Background and ObjectivesThe number of older adults living alone is increasing globally, often with varied risks and resilience capacities. Digital technologies may help mitigate these risks, but their potential remains poorly understood. This review maps evidence on digital technologies in social and health care interventions for older adults living alone, focusing on technology types, functions,
Studies showing that large-scale public health interventions in early life have lastingconsequences are still scarce and rarely disclose the mechanisms. In 1931–1946, the Swedishstate reformed the childbirth institutional system that led to the openings of the new maternitywards and to the gradual decline in home deliveries assisted by midwives. Maternity wardsoffered improved conditions for a mot
Bee-mediated pollination plays a crucial role in sustaining global food production. However, while the demand for these pollination services is increasing, many bee species are in decline. To address this discrepancy, farmers use managed bee species to improve crop pollination. One key factor affecting pollination efficiency is the affinity for the crop of interest (i.e., the extent to which a bee
To reverse biodiversity loss, creating resilient ecological networks has been promoted in policy and practice. However, we argue that emphasising networks within policy without clear conservation prioritisations may direct focus away from ecological processes important for population persistence. We studied the rationale for resilient ecological networks represented in a policy context, by reviewi
We have investigated the bacterial decomposition of dissolved organic matter (DOM) extracted from the organic layer of a boreal forest soil and filtered at a pore size of 0.2 µm. This DOM source has previously been extensively characterized and contains approximately equal amounts by carbon of a colloidal fraction, mainly composed of carbohydrates, and a fraction of molecularly dissolved DOM. Here
Context: Land-use intensification to increase yields is often detrimental to biodiversity undermining the provision of ecosystem services. However, it is questionable if ecosystem service providers contribute to ecological intensification by achieving the same or higher yields than conventional high-intensity agriculture. Objectives: In this study, we aimed to disentangle the effects of local and
Human activities in deciduous forests over the past centuries have influenced associated species. To reduce extinction risks and mitigate population declines, there is growing interest in forest conservation and restoration, including initiatives by the European Union (EU). For resulting restoration and conservation practices to succeed, it is essential to know which forest characteristics promote
Pollinators are estimated to benefit the reproduction of three-quarters of global leading crop species and contribute to 3%–8% of the total global food production. Ongoing declines in pollinator populations have raised concerns about repercussions for food security. Thus, there is a need to better understand how agricultural yields depend on pollinator abundance. Here, we established yield–pollina
Agricultural intensification is widely recognised as a primary driver of pollinator loss, but the success of land-management actions designed to remediate its impact is often mixed. Payments to farmers to increase habitat connectivity or the availability of floral and nesting resources may only result in short-term gains or even unintended consequences. The reasons may lie in changes to interactio
Bioenergy derived from agricultural biomass can contribute to meeting the rising demand for renewable energy. To estimate the agricultural sector's potential to contribute to bioenergy, it is crucial to understand what motivates farmers to increase agricultural feedstock production sustainably. Through eight semi-structured interviews and online surveys with 174 farmers in southern Sweden, we expl
Intensity Analysis (IA) of land use and land cover change (LULCC) is important to support policy and practice. We applied IA to analyse LULCC in Sironko catchment, Uganda. Results show that agricultural land, forest, and wetland reduced by 8%; 32%; and 20% between 1986-2000. Between 2000-2016, forest, wetland, and built-up areas increased by 84%, 5%, and 57%. Active gainers between 1986-2000 were
Agricultural intensification and expansion are regarded as main drivers of biodiversity loss. This conclusion is mainly based on observed declines of local diversity (α-diversity), while effects on community composition homogenization (decrease of β-diversity) at a larger spatial scale are less well understood. Carabid beetles and spiders represent two widespread guilds and are important predators
Neonicotinoids, systemic insecticides that are distributed into all plant tissues and protect against pests, have become a common part of crop production, but can unintentionally also affect non-target organisms, including pollinators. Such effects can be direct effects from insecticide exposure, but neonicotinoids can affect plant physiology, and effects could therefore also be indirectly mediate
Organismal abundance tends to decline with increasing body size. Metabolic theory links this size structure with energy use and productivity, postulating a size–abundance slope of −0.75 that is invariant across environments. We tested the robustness of this relationship across gradients of protist species richness (1–6 species), temperature (15°C–25°C) and time. Using replicated microcosms, we pro

Resource competition between wild pollinators and managed honeybees (Apis mellifera) has the potential to detrimentally impact insect biodiversity as well as wild plant and crop pollination. As honeybees are central place foragers, their competitive impact on wild bees is expected to be structured by hive proximity, in conjunction with foraging decisions related to landscape-level resource availab
Abstract The discussion of the transition to farming in southern Africa and the formation of Early Iron Age society, referred to in Mozambican archaeology as the Early Farming Communities (EFC), is complicated by the lack of surveys in key areas of intensive contacts.
