1. 6. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

   University essay from SLU/Dept. of Soil and Environment

   Author : Liliana Marcela Daza Gomez; [2023]
   Keywords : nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

   Abstract : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. READ MORE

3. 7. The impact of CO2 fertilisation on foliage in West and East Africa

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Gaetane Demyttenaere; [2023]
   Keywords : Physical geography and ecosystem analysis; CO2 fertilisation; semi-arid ecosystems; remote sensing; Normalised Difference Vegetation Index; Earth and Environmental Sciences;

   Abstract : Anthropogenic impact on terrestrial ecosystems continues to grow as we further enhance atmospheric Carbon Dioxide (CO₂) concentrations. The changing climatic conditions and direct influence of CO₂ on vegetation has a big impact on ecosystem functions. READ MORE

4. 8. Water use efficiency in agricultural irrigation in Egypt: A qualitative study on the complexities of utilising fossil groundwater resources in the face of water scarcity

   University essay from Lunds universitet/Ekonomisk-historiska institutionen

   Author : Johannes David Huber; [2023]
   Keywords : Water scarcity; water use efficiency; agricultural irrigation; desert farming; sustainability; groundwater extraction; Nubian Sandstone Aquifer System NSAS ; Business and Economics;

   Abstract : This study examines the adaptive capacity of desert farming in Egypt to imminent water scarcity and discusses the sustainability of fossil groundwater extraction. Through qualitative semi-structured expert interviews, the study identifies clear research and data gaps related to the Nubian Sandstone Aquifer System (NSAS) and highlights the need for a nuanced approach to fossil groundwater extraction that focuses on water use efficiency improvements.

5. 9. Post-Fire Vegetation Recovery Monitoring using MODIS Time Series: A Case Study in California

   University essay from KTH/Geoinformatik

   Author : Julia Edje; [2023]
   Keywords : vegetation recovery; MODIS; HRT; EVI; fire; burn severity; land cover; climate zone; California;

   Abstract : Human-caused forest fires have increased in magnitude and frequency, affecting global vegetation and requiring a re-evaluation of fire regimes. Changing fire regimes have led to reduced burned areas in fire- dependent ecosystems and increased areas in fire-independent ecosystems, resulting in changes in land cover and posing a threat to native plant communities.
