The Special Section on Post-growth food systems for a just social-ecological transition within planetary boundaries explores post-growth and degrowth approaches that advocate for sufficiency, care, regeneration, and the democratization of food systems. It shows that post-growth food initiatives face multiple structural barriers, including capitalist systems that prioritize profit over ecological a
Predictive models used in decision making, such as QSARs in chemical regulation or drug discovery, call for evaluated approaches to quantitatively assess associated uncertainty in predictions. Uncertainty in less reliable predictions may be captured by locally varying predictive errors. In the current study, model-based bootstrapping was combined with analogy reasoning to generate predictive distr
The old city of Fez, Morocco, classified as Heritage of Humankind by the UNESCO, is subject to an integrated rehabilitation plan running over 15 years. The plan aims at restoring and preserving the economy, cultural value, and social heritage of the old city. The study follows a system dynamics approach to describe and analyze the rehabilitation plan in order to identify the strengths and defects
Scenario: Using adaptive dynamic theory, expose a monomorphic prey population to two habitat types and a visual predator. Questions: What circumstances can lead to the evolution of polymorphic crypsis? How is the outcome affected by the dispersal pattern of the prey and predator, by the amount of predation, and by the trade-off strength between the habitats? Mathematical method: I modelled three d
This statement examines the relation of the resting ECG to its technology. Its purpose is to foster understanding of how the modern ECG is derived and displayed and to establish standards that will improve the accuracy and usefulness of the ECG in practice. Derivation of representative waveforms and measurements based on global intervals are described. Special emphasis is placed on digital signal
Indonesia has experienced rapid land use change over the last few decades as forests and peatswamps have been cleared for more intensively managed land uses, including oil palm and timber plantations. Fires are the predominant method of clearing and managing land for more intensive uses, and the related emissions affect public health by contributing to regional particulate matter and ozone concent
This study aims to verify the effect of physically removing the outer surface of contaminated concrete on total contents and on potential mobility of pollutants by means of leaching tests. Reclaimed concrete from 3 industrial sites in Sweden were included: A tar impregnated military storage, a military tar track-depot, as well as concrete constructions used for disposing of pesticide production su
In Information Gap Decision Theory (IGDT) a system is said to be robust to uncertainty if specified goals are achieved with satisfaction despite large info-gaps. Under this theory an info-gap expresses the disparity between what is known and unknown in structures for which uncertainty is judged as severe. We discuss how robustness in IGDT can be merged with a perspective on risk which allows for d
Technical Systems, Structures and Infrastructures (SSI) ought to be designed to be safe under current but also future environmental (climate) conditions. Therefore, there is a need to rigorously identify procedures to systematically consider different climate conditions into the risk assessments. In this paper, we consider climate change in the risk assessment of a Passive Containment Cooling Syst
Cation release rates to catchment runoff from chemical weathering were assessed using an integrated catchment model that included the soil's unsaturated, saturated and riparian zones. In-situ mineral dissolution rates were calculated in these zones as a function of pH, aluminum and dissolved organic carbon (DOC) concentrations along a hillslope in Northern Sweden where soil water was monitored ove
Endocrine disrupting chemicals (EDCs) have the potential to affect development and reproduction in gastropods. However, one is today lacking basic understanding of the Molluscan endocrine system and one can therefore not fully explain these EDC-induced affects. Furthermore, only a few genes that potentially may be connected to the endocrine system have been sequenced in gastropods. An example is t
Monte Carlo simulation is a useful technique to propagate uncertainty through a quantitative model, but that is all. When the quantitative modelling is used to support decision-making, a Monte Carlo simulation must be complemented by a conceptual framework that assigns a meaningful interpretation of uncertainty in output. Depending on how the assessor or decision maker choose to perceive risk, the
The response of the terrestrial water cycle to global warming is central to issues including water resources, agriculture and ecosystem health. Recent studies indicate that aridity, defined in terms of atmospheric supply (precipitation, P) and demand (potential evapotranspiration, E p) of water at the land surface, will increase globally in a warmer world. Recently proposed mechanisms for this res
We describe the process of building a climate service centred on regional climate model results from the Rossby Centre regional climate model RCA4. The climate service has as its central facility a web service provided by the Swedish Meteorological and Hydrological Institute where users can get an idea of various aspects of climate change from a suite of maps, diagrams, explaining texts and user g
Nascent US carbon markets reward farmers for reforesting agricultural land, with consequent ecological co-benefits. We use a dynamic optimization model to determine the likelihood of an orchard farmer in northern California converting to forest under 90 plausible future scenarios. We find reforestation to be a highly unlikely outcome, occurring only 4.0% of the time under current economic, biophys
The critical rates of extraction of some metals was explored using a methodology based on the thinking behind critical loads for sulphur and nitrogen deposition developed in Europe 1990-2010. With a long term sustainability view in mind, critical rates based on 5,000 and 10,000 years were estimated and found to widely exceed the present extraction rates. Huge advances in recycling, as well as a si
The total resources form copper, zinc and lead was estimated from a reworking of the literature. The data was used as input to the integrated systems dynamics model BRONZE, and used to estimate the global supply of these metals and the by-products antimony, indium, germanium, tellurium, cadmium, bismuth and selenium. The runs show that copper, zinc and lead go through peak production around 2050 a
The global supply of cobalt was simulated by combining 3 different system dynamics models; BRONZE, PGM and STEEL. The present use of cobalt shows a low degree of recycling and systemic losses are significant. The reserves of cobalt are not very large (20-25 million ton extractable) as compared to metals like copper, zinc or iron, and after 2170 cobalt will have run out under a business-as-usual sc
Interaction of synthetic TiO2 (anatase) nanoparticles in aqueous suspension at pH 5 was investigated as a function of time in the presence of various organic molecules in terms of adsorption and aggregation behaviour. ζ-potential and average particle diameter were determined with electrophoretic and dynamic light scattering, respectively, while batch adsorption experiments were used to quantify th
Studies on the natural human exposures to fine particulate matter (PM2.5) and their elements composition are practically non-existent in South America. In order to understand the natural exposure of the typical Brazilian population to PM2.5 and their trace element composition, we measured PM2.5 concentrations and collected mass on filters for nine continuous hours during a typical workday of volun
