Multiple trade-offs likely occur between pesticide use, pollinators and yield (via crop flowers) in pollinator-dependent, mass-flowering crops (MFCs), causing potential conflict between conservation and agronomic goals. To date, no studies have looked at both outcomes within the same system, meaning win-win solutions for pollinators and yield can only be inferred. Here, we outline a new framework
National policy styles and path-dependencies are affecting the abilities of Baltic Sea countries to deliver on their commitments under the Helsinki Convention. This article synthesizes evidence and insights from studies relating to the provisions on agricultural nutrient management, a main source of marine pollution. We contend that governments that are strongly concentrated vertically, while frag
Many bird species typical to farmland have declined in numbers in recent decades. Some farmland bird species occur outside farmland in other open man-made habitats, such as forest clear-cuts. Given that in Sweden the total area of clear-cuts (5–6 %) almost equals that of farmland (8 %), clear-cuts have the potential to be an important habitat for some farmland birds. We investigated how bird commu
In ecology, multifunctionality metrics measure the simultaneous performance of multiple ecosystem functions. If species diversity describes the variety of species that together build the ecosystem, multifunctionality attempts to describe the variety of functions these species perform. A range of methods have been proposed to quantify multifunctionality, successively attempting to alleviate problem
The Swedish carbon tax of 1991, one of the first of its kind, has positioned Sweden as a forerunner in climate governance. It is often depicted an international success and today constitutes the backbone of Swedish climate policy. At first, however, the tax received widespread criticism and had limited political support. The policy design process was short, with limited time for deliberation. Whil
When Sweden adopted its carbon tax in 1990, it was as one of the first of its kind worldwide. While the adoption of the tax has been attributed to its inclusion in the Swedish tax reform, undoubtedly playing a crucial role, the reform does not in itself explain how the Swedish carbon tax came about or why it became part of the reform package in the first place. In this article, we present a case s
The majority of soil carbon (C) is stored in organic matter associated with reactive minerals. These mineral-organic associations (MOAs) inhibit microbial and enzymatic access to organic matter, suggesting that organic C within MOAs is resistant to decomposition. However, plant roots and rhizosphere microbes are known to transform minerals through dissolution and exchange reactions, implying that
Most landscapes are comprised of multiple habitat types differing in the biodiversity they contain. This is certainly true for human modified landscapes, which are often a mix of habitats managed with different intensity, semi-natural habitats and even pristine habitats. To understand fundamental questions of how the composition of such landscapes affects biodiversity conservation, and to evaluate
The daily transition between day and night, known as the diel cycle, is characterised by significant shifts in environmental conditions and biological activity, both of which can affect crucial ecosystem functions like pollination. Despite over six decades of research into whether pollination varies between day and night, consensus remains elusive. We compiled the evidence of diel pollination from
Sweden’s grocery distribution is routed through a limited number of upstream hubs and relies on corridors and ferry links. When disruptions affect a hub or a critical link, reallocations propagate fast and travel times increase, with some areas losing coverage temporarily. Decentralising the whole system is costly, so targeted resilience options must be evaluated. The purpose of this thesis is to
Since its inception, Estonia has been at the forefront of innovation in terms of e-governance and applications of online systems into various aspects of Estonians’ lives. In 2014 Estonia opened up it’s digital borders and launched a digital economic citizenship - e-Residency - available to anyone in the world for using Estonian e-services to register and manage a company online. In May 2018, 5000
Kenya’s rapid, unplanned urban development and rising pressure for cities to adapt to climate change and become more climate change resilient has led to the realisation that more needs to be done. In Nairobi, increasing access to mobile technology and internet access, faster internet speeds, and the growing technology sector could be possible means to facilitate urban climate change resilience (UC
Enligt lagen (2003:778) om skydd mot olyckor, LSO, har den som äger en byggnad eller bedriver verksamhet i byggnaden det yttersta ansvaret för sitt brandskydd. I skälig omfattning ska det finnas utrustning för livräddning vid brand, och i övrigt ska åtgärder vidtas för att förebygga samt begränsa skador till följd av brand. Det är kommunernas ansvar att utföra tillsyn på brandskyddet så att dettaAccording to Swedish Law (2003:778) on protection against accidents, LSO, the one who owns a building or conducts operations in a building has the ultimate responsibility of their fire protection. To a reasonable extent, there must be equipment for lifesaving in the event of a fire, as well as other measures which must be taken to prevent fire and limit damage as a result of fire. In this study, t
Backlash is often present in mechanical transmission systems and can be one of the main causes that severely limits control systems performances. In this work are presented a number of adaptive algorithms that through a proper feedforward nonlinear action try to compensate the backlash. Due to the nonlinear nature of the problem, convergency proofs are very difficult; nevertheless simulations show
Neonicotinoids are implicated in bee declines and laboratory studies imply that they impair the bee immune system, thereby precipitating a rise in pathogen levels. To establish whether such synergisms reduce bee performance in real-world agricultural landscapes, we analysed the microbial composition of the bumblebee (Bombus terrestris) samples from our recent landscape study on the impacts of fiel
Agricultural management practices and extreme weather events associated with climate change can influence the diversity and abundance of arbuscular mycorrhizal fungi (AMF) with potential consequences for crop production. However, the importance of the interactive effects of long-term agricultural management and extreme weather events on AMF communities in agricultural soils is not yet fully explor
Yield loss caused by insect pests remains a substantial problem in agriculture. Chemical control, with potential negative effects on non-target organisms, is still the main tool for pest management. For pest species with limited dispersal capacity, rotation of the crop in time and space has potential as an alternative management measure. This is particularly important in organic farming, where mos
