  1. 1. Of Chaos And Clockworks : A Formal Criticism Of The Modern Sustainability Paradigm

    University essay from Högskolan i Gävle/Miljövetenskap

    Author : Sebastian Arnström; [2023]
    Keywords : sustainability; sustainability science; complexity; complex adaptive systems; Earth system; Earth system science; resilience theory; the adaptive cycle; chaos theory; eco-theology;

    Abstract : This thesis is a critical review of two central theories in the modern sustainability paradigm – namely… (1) the theory that the Earth’s geosphere, hydrosphere, biosphere and atmosphere form a complex adaptive system – the Earth system, and (2) the theory that all human activities are intrinsically dependent on, and constrained by, non-anthropogenic states and processes in the Earth system. The thesis explains the origins and the logic of these theories, and subjects them to formal, semi-formal and comparative criticism. READ MORE

  3. 2. BVOC emission variability for Norway spruce (Picea abies) in Hyltemossa, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexandra Arnsteg; [2022]
    Keywords : BVOC; isoprene; monoterpenes; induced emission; light dependency; temperature; Norway spruce.; Earth and Environmental Sciences;

    Abstract : Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack.

  4. 3. -2,32m: How to protect a city under water?

    University essay from KTH/Arkitektur

    Author : Jonatan Weiber; [2022]
    Keywords : Kristianstad; Flooding; Ecosystem services; Helge Å; Urban Design;

    Abstract : Kristianstad is a city of 41.000 inhabitants in southern Sweden.

This has caused parts of Kristianstad to have the lowest point in Sweden, -2,32 meters below ocean level. READ MORE

  5. 4. Closed ecological life support systems : cycling of carbon, nitrogen and water

    University essay from SLU/Dept. of Ecology

    Author : Hugo Persson; [2020]
    Keywords : closed ecological system; cycling; closure; life support; biosphere; CEEF; MELiSSA; Biosphere 2; bioregenerative; CELSS; environmental;

    Abstract : Materially closed life support systems containing biological components that provide atmosphere, food and water for a human crew has been investigated for use in space travel since the 1960s. The internal cycling of organic material is the essence of these systems and their design and function is the question at issue for this thesis, which has been conducted as a literature study.

  6. 5. ICOS Atmospheric Stations: Spatial Characterization of CO2 Footprint Areas and Evaluating the Uncertainties of Modelled CO2 Concentrations

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ida Storm; [2020]
    Keywords : Geography; GIS; ICOS; Carbon dioxide; Modelling; Earth and Environmental Sciences;

    Abstract : The main purpose of this thesis is to present and analyze spatial characteristics of 31 different European atmospheric measurement stations in the ICOS (Integrated Carbon Observation System) station network. The characterization includes quantification of where air arriving at the stations can be expected to have come from, as well as a breakdown of what these areas cover with regards to land cover, point source emissions and population.
