1. 11. Evaluating drought impacts on ecosystem water use efficiency of three different boreal forest sites

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

   Författare :Tim Schacherl; [2021]
   Nyckelord :flux data; carbon uptake; water deficit; Sweden; drought resistance; nitrogen; Eddy covariance;

   Sammanfattning : European boreal forests are the biomes most affected by climate change. For example, extreme weather events such as droughts are expected to become more frequent and severe. Especially in the summer months, droughts can drastically impact the carbon and water exchanges of boreal forests. LÄS MER

3. 12. Shifting from Voluntary to Mandatory Mechanisms to scale up Sustainable Public Procurement – The Integration of Voluntary Sustainability Standards into Public Procurement and Trade Policies

   Magister-uppsats, Lunds universitet/Institutionen för handelsrätt

   Författare :Farhod Asrolov; [2021]
   Nyckelord :green public procurement; sustainable public procurement; corporate social responsibility; CSR; sustainability; environmental protection; social protection.; Law and Political Science;

   Sammanfattning : Green and Sustainable Public Procurement are widely recognized as the strategic lever to promote innovation, sustainability, and the strategic tool on environmental and social protections. The extension of sustainability beyond environmental aspects, especially the integration of social and economic aspects is becoming common grounds in most jurisdictions. LÄS MER

4. 13. Legacy effects of spring temperature anomalies on seasonal productivities in northern ecosystems

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

   Författare :Hanna Marsh; [2021]
   Nyckelord :Physical geography; Ecosystem analysis; Northern ecosystems; Legacy effects; Climate Change; Gross Primary Production; Earth and Environmental Sciences;

   Sammanfattning : Legacy effects of spring temperature anomalies on seasonal productivities in northern ecosystems Direct and lagged effects from spring temperature anomalies for the time-period 2001-2018 have been investigated for northern ecosystems (> 30°N). Three different data sets of Gross Primary Production (GPP) estimates (GOSIF, NIRvGPP and FLUX GPP) have been used in tandem with concurrent climate data to find significant correlations between spring growth and temperature anomalies and subsequent growing seasons.

5. 14. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

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

   Författare :Malin Ahlbäck; [2020]
   Nyckelord :Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

   Sammanfattning : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. LÄS MER

7. 15. Customized Processor Design for 5G Data Link Layer Processing

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Patric Wargéus; Lukas Forsberg; [2020]
   Nyckelord :Technology and Engineering;

   Sammanfattning : This thesis aims to explore the workflow related to designing an application specific instruction-set processor (ASIP). An ASIP is a processor similar to a hardware accelerator (HAC) in terms of performance and efficiency, but containing elements of general purpose processors (GPPs) when it comes to programmability and flexibility.
