  1. 1. The Promise of a Green Revolution : Conceptions of climate change and sustainability in local movements objecting to mining establishment

    University essay from Uppsala universitet/Institutionen för kulturantropologi och etnologi

    Author : Caroline Reinhammar; [2023]
    Keywords : ;

    Abstract : This study explores how vernacular understandings of climate change and sustainability are formed in relation to local disputes concerning mineral exploration. In a search for a solution to climate change, the interest in rare earth elements (REEs), and other metals used in green technology has resulted in granting mining companies processing concessions in Sweden.

  3. 2. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Tsai-wei Tang; [2022-01-26]
    Keywords : N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

    Abstract : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. READ MORE

  4. 3. Disparate Lives, Fractured Mineral: Toxic Displacement in the Global Economy of Asbestos

    University essay from Lunds universitet/Humanekologi

    Author : Nicholas Surber; [2018]
    Keywords : Eternit; economy of asbestos; displacement; abstract space; socio-natural transformation; slow violence; toxicity; environmental public health; ecological Marxism; post-humanism; Social Sciences;

    Abstract : The established scientific reality of asbestos is that (a) asbestos is toxic at a minuscule dose, and (b) exposure should be avoided whenever possible, with the evidence expanding almost exponentially over the past century. The purpose of this research is to explore the historical and global socio-natural entanglements of the economy of asbestos and the resulting mechanisms at play to occlude and marginalise the toxicity and emphasise profitability.

    Abstract : Jämfört med andra himlakroppar i vårt solsystem så finns det få välbevarade nedslagsstrukturer på jorden. Vi vet att jorden har påverkats av nedslag från rymden i lika stor utsträckning som övriga planeter och att dessa nedslag har influerat jordens geologiska och biologiska utveckling. READ MORE

  6. 5. Mineral nitrogen in spring in two cropping systems with permanent nitrogen supply

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Su Liu; [2012]
    Keywords : conservation tillage; soil; crop; farming system; rotation; nitrogen mineralization; nitrogen leakage;

    Abstract : The purpose of this study is to find out nitrogen (N) transformation in rotation system from previous crop to succeeding crop in both conventional cropping system and conservation tillage cropping system. The conservation tillage cropping system used some methods like legumes and catch crop with lower inputs of fertilizers and pesticides. READ MORE
