The 1990s were significant for several events promoting environmental protection and the sustainable use of natural resources. For instance, both the United Nations Conference on Environment and Development in 1992, which stressed the need to stop the overconsumption of natural resources and the United Nations Framework Convention on Climate Change endorsed a framework to combat climate change. Si
Context Up-to-date information on infant survival after extremely preterm birth is needed for assessing perinatal care services, clinical guidelines, and parental counseling. Objective To determine the 1-year survival in all infants born before 27 gestational weeks in Sweden during 2004-2007. Design, Setting, and Patients Population-based prospective observational study of extremely preterm infant
The aim of this thesis is to develop statistical models to reconstruct past land cover composition and human land use based on fossil pollen records over Europe for different time periods over the past 6000 years. Accurate maps of past land cover and human land use are needed when studying the interaction between climate and land surface, and the effects of human land use on past climate. Existing
Extracting information about emerging events in large study areas through spatiotemporal and textual analysis of geotagged tweets provides the possibility of monitoring the current state of a disaster. This study proposes dynamic spatio-temporal tweet mining as a method for dynamic event extraction from geotagged tweets in large study areas. It introduces the use of a modified version of ordering
Components of dissolved organic matter (DOM) span from sub-nm molecules to colloidal aggregates of several hundred nm. The colloidal fraction is important for the transport of organic matter and associated elements in the environment, and for the stability of DOM constituents with respect to microbial decomposition. This study focuses on the colloidal properties of DOM extracted from spruce forest
The isolation of mitochondria from potato tubers (Solanum tuberosum L.) is described, but the methodology can easily be adapted to other storage tissues. After homogenization of the tissue, filtration and differential centrifugation, the key step is a Percoll density gradient centrifugation. The Percoll gradient contains two parts: a bottom part containing Percoll in 0.3 M sucrose, and a slightly
Context: The global demand for food is expected to continue increasing for decades, which may drive both agricultural expansion and intensification. The associated environmental impacts are potentially considerable but will depend on how the agricultural sector develops. Currently, there are contrasting regional developments in agriculture; expansion and/or intensification in some regions and aban
The EU's Common Agricultural Policy (CAP) has had limited success in mitigating agriculture's environmental degradation. In this paper we simulate the impacts of the 2013 “greening” reform on biodiversity and ecosystem services in environmentally contrasting landscapes. We do this by integrating an agent-based model of structural change with spatial ecological production functions, and show that t
Control of crop pests by shifting host plant availability and natural enemy activity at landscape scales has great potential to enhance the sustainability of agriculture. However, mainstreaming natural pest control requires improved understanding of how its benefits can be realized across a variety of agroecological contexts. Empirical studies suggest significant but highly variable responses of n
Push-pull technology (PPT) is a strategy for controlling agricultural pests, improving soil fertility, diversifying farm output, and reducing gender and age disparities. The benefits of PPT have been demonstrated in East Africa, but efforts to upscale its adoption can face many challenges. Agroecosystems comprise social-ecological networks, with interactions that transcend spatial and temporal sca
The WHO/UNICEF Joint Monitoring Program (JMP) for Water Supply, Sanitation and Hygiene (WASH) produces global estimates of the real situation of access to water, sanitation and hygiene services, and sanitation and hygiene in households, educational institutes and health care facilities; however it is lacking data on schools in Kazakhstan. Thus, the aim of this research was to assess access to WASH
We determined the 2025-2040 impact of climate and land use land cover change on streamflow in the Sironko catchment. LULCC was predicted using Cellular Automata Markov. The climate was statistically downscaled from the 29 GCMs of the IPCC Fifth Coupled Model Intercomparison Project using the delta method of the Agricultural Model Inter-comparison and Improvement Project under five climate regimes
Biodiversity offsetting (BO) is aimed to counterbalance biodiversity impacts from development projects. In Sweden, interest in BO within urban planning has grown since the mid-to-late 1990s, when the approach was first piloted in the municipality of Lomma. Because urban planning often involves non-protected nature, BO is not legally mandated but instead implemented on a voluntary basis. So far, ev
Rapid deforestation has been well-documented in Colombia after the 2016 peace agreement with FARC. While many analysis using remote sensing identify land cover change, structural connectivity variables are less studied for understanding landscape transformation. In this work, we used data from the Landsat archive from 2011 to 2021, the Continuous Change Detection and Classification algorithm (CCDC
Diverse forest landscapes contribute to reaching various forest policy goals. Understanding how the diversity of forests in a landscape is distributed among forest properties and how it is related to biogeographical and ownership factors can be helpful for effective policy implementation. We created a forest characteristics-based typology of non-industrial private forest properties aiming to captu
Soil aggregation is a dynamic process influenced by physical, chemical and biological factors; however, their individual and combined effect on the formation and turnover of aggregates is not well understood. The aim of this study was to examine incorporation of fresh litter inputs of different physicochemical properties including their carbon-to-nitrogen (C/N) ratio – maize (C/N = 12) and straw (
Declining butterfly abundance over recent decades coincides with both habitat loss and increasingly warmer springs. Warmer temperatures could pose a problem for ‘capital’ breeders, especially those species that enter winter diapause as a pupa or adult, since a higher metabolic rate pre-eclosion is expected to further deplete lipid stores needed for egg production. We undertook an experiment on Pie
Trends for the atmospheric deposition of sulphur (S) and inorganic nitrogen (inorg-N) to forests and changes in the forest soil water chemistry in Sweden have been assessed since 1985, with special focus on the last 25 years, based on measurements within the Swedish Throughfall Monitoring Network (SWETHRO). The reductions in the deposition of S and inorg-N in the southern part of Sweden correspond
Background: Increasing carbon stock in standing forests is one of the proposed ways to mitigate climate change. However, in production forests, this typically would lead to reduced harvesting possibilities and thus reduced financial gain for the forest owners. The size of this reduction should depend on the chosen target level of the carbon stock as well as the required speed of accumulation. Furt
