1. 1. Shifting focus from yields to food supply : an evaluation of the ‘number of people fed per hectare’ indicator at farm and national level

   Master-uppsats, SLU/Department of Molecular Sciences

   Författare :Ida Ekqvist; [2024]
   Nyckelord :Land use efficiency; Sustainability indicators; Agricultural productivity; Food production;

   Sammanfattning : The challenge of feeding a growing global population while reducing the pressure on climate and ecosystems has gained much attention in research over the last decades. A crucial yet often overlooked aspect in research addressing this complex challenge is the efficiency of food production in meeting nutritional needs within the constraints of global cropland resources.

3. 2. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Colin Potter; [2023]
   Nyckelord :Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

   Sammanfattning : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

4. 3. Agricultural-induced deforestation emissions and drivers of agricultural land use change in Indonesia

   Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

   Författare :Alida Johannsen; [2022]
   Nyckelord :Deforestation; Agricultural Trade; Land use; Structural Decomposition Analysis; Multi regional Input-Output; Indonesia; Business and Economics;

   Sammanfattning : Tropical deforestation, primarily driven by the expansion of agricultural land use, is responsible for significant global CO2 emissions, threatening current climate goals. Indonesia experiences one of the highest deforestation rates, endangering its rich biodiversity and human health. LÄS MER

5. 4. Randomized heuristic scheduling of electrical distribution network maintenance in spatially clustered balanced zones

   Master-uppsats, KTH/Geoinformatik

   Författare :Carolina Offenbacher; Ellen Thornström; [2022]
   Nyckelord :Capacitated Vehicle Routing Problem; Electrical distribution network; Heuristic algorithm; Scheduling; Handelsresandeproblemet; Eldistributionsnätverk; Heurustik algortim; Schemaläggning;

   Sammanfattning : Reliable electricity distribution systems are crucial; hence, the maintenance of such systems is highly important, and in Sweden strictly regulated. Poorly planned maintenance scheduling leads unnecessary driving which contributes to increased emissions and costs. LÄS MER

7. 5. Spatio-temporal analysis of groundwater-dependent precipitation based on Lagrangian moisture tracking

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Daowei Li; [2022]
   Nyckelord :Groundwater abstraction; groundwater dependent precipitation; ERA5 precipitation; Utrack; Lagrangian model.;

   Sammanfattning : Groundwater abstraction for irrigation use has steadily increased over the past decades, resulting in additional evaporation to the atmosphere, and increased precipitation. The precipitation stemming from groundwater irrigation (or Groundwater-dependent precipitation) has received little attention during recent years and is solely researched by the Eulerian model.
