1. 1. Investments in Academic Renewable Electricity Generation Technology Spin-Offs : A Qualitative Study on High Capital Limitations for Underexplored Renewable Energy Sources

   Master-uppsats, Uppsala universitet/Industriell teknik

   Författare :Yann Braune; [2020]
   Nyckelord :Renewable Energy Generation Technologies REGT ; Underexplored Renewable Energy Sources; University Spin-Off; Funding Ecosystem; Funding Gap; Degree of Utilization; Cross-Disciplin;

   Sammanfattning : Due to an intensified climate change discourse, renewable energy technologies find higher attention within the energy system and increasingly compete with traditional energy conversion systems. Electricity is progressively being generated through renewable electricity generation technologies (REGT) which harness naturally existing energy fluxes (wind, tide, heat, sun) and convert it to electricity.

3. 2. Investigating future land use scenarios: consequences for food production and grassland preservation in the steppe biome, Orenburg province of Southwestern Russia

   Master-uppsats, Stockholms universitet/Stockholm Resilience Centre

   Författare :Nataliia Pustilnik; [2020]
   Nyckelord :land use change; scenarios; shared socio-economic pathways; land use-change modelling; steppe; grasslands;

   Sammanfattning : Many land systems experience massive ecological pressure due to ongoing land use changes for the increasing demand for food, but also need to sustain essential ecosystem services. Computer-based model scenarios help to anticipate the consequences of different socio-economic future transition pathways for humans and nature and evaluate trade-offs between various demands on land.

4. 3. Sojans roll i världen

   Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Anton Andersson; Astrid Berg; Emil Rådkvist; Sara Wennberg; Jacob von Zweigbergk; [2019]
   Nyckelord :Soybean;  Ecosystem services;  Conversion of natural ecosystem; USA; Brazil;  Argentina;  Glycine max; Soybean Consumption;

   Sammanfattning : The soybean has become one of the world's largest agricultural commodities, with growth in soybean production being driven by two prime demands, animal feed and food products. The purpose of this report is to analyze the role of the soybean in the world and study its consumption in order to make a projection of future demand. LÄS MER

5. 4. Total carbon sequestration during an entire rotation period of oil palm in northern Borneo

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Josefin Runesson; [2019]
   Nyckelord :oil palm; carbon balance; carbon sequestration; land use change; soil carbon; carbon credits;

   Sammanfattning : Considerable amounts of carbon (C) has been lost from tropical forests as a result of continuous conversion of tropical forests into oil palm plantations. Therefore, a better understanding of the C budget and potential sequestration rate in oil palm plantations and how it compares to natural forests is needed. LÄS MER

7. 5. Estimating contemporary methane emissions from tropical wetlands using multiple modelling approaches

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

   Författare :Shubangi Lamba; [2012]
   Nyckelord :LPJ-GUESS; uppskalning; modellering; tropisk våtmark; metanutsläpp; methane emissions; tropical wetlands; modelling; upscaling; physical geography; ecosystem analysis; Earth and Environmental Sciences;

   Sammanfattning : Estimating contemporary methane emissions from tropical wetlands using multiple modelling approaches Methane gas makes a significant contribution to the greenhouse effect happening on the planet. In modern times, natural wetlands are the biggest source of methane gas as compared to other sources of natural origin. LÄS MER
