1. 1. Future climate suitability of shade trees in cocoa agroforestry systems in West Africa and shade tree diversity’s impact on farm microclimate : A Minor Field Study

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Jonna Halonen; [2023]
   Keywords : species distribution modeling; cocoa agroforestry; shade trees; West Africa; microclimate; distributionsmodell; kakaoskogslantbruk; skuggträd; Västafrika; mikroklimat;

   Abstract : Shade trees’ implementation into cocoa agroforestry systems in tropical West Africa has proven to have a high potential in increasing farm resilience and mitigating climate change. However, no studies have yet examined the potential future climate suitability for shade trees in the region, which is important when deciding which shade trees to implement. READ MORE

3. 2. Gas Chromatography Mass Spectrometry Analysis of Epoxides in Gas Phase Reactions

   University essay from KTH/Kemi

   Author : Stephanie Kylington; [2022]
   Keywords : organic peroxy radicals; unsaturated alkenes; TD-GCMS; Tenax® TA; internal standard; organiska peroxidradikaler; omättade alkener; TD-GCMS; Tenax® TA; intern standard;

   Abstract : En nyligen genomförd studie visade att reaktioner mellan vissa radikaler och omättade alkener är snabbare vid rumstemperatur än vad man tidigare har trott. Dessa reaktioner är viktiga för atmosfäriska oxidationscykler och följaktligen var syftet med detta masterprojekt att beräkna hastighetskonstanterna för dessa reaktioner mellan metyljodid och 1-jodidpentan med tetrametyletylen, isopren och limonen vid rumstemperatur genom att kvantifiera respektive epoxid; tetrametyloxiran, isoprenmonoxid och limonen 1,2 epoxid, som producerades.

4. 3. Climate Simulations of an Exoplanet with a Slab Ocean: A 3D Model Intercomparison of various GCMs

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Moa Biserud; [2022]
   Keywords : Climate simulations; GCM; ROCKE-3D; Exoplanet; Slab Ocean; Qflux=0;

   Abstract : Three-dimensional (3D) planetary general circulation models (GCMs) have been derived from global climate models used to project 21st century changes in Earth's climate. GCMs are used to address questions regarding the climate-and habitability aspects of terrestrial planets within the solar system and assess the habitability of planets outside of the solar system, so called exoplanets.

5. 4. Groundwater resources and vulnerability for mountain communities in the Andes

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Raheela Fahd; [2020]
   Keywords : ;

   Abstract : The purpose of the thesis is to review the effect of ongoing climate change and population growth ongroundwater resources of Katari Basin (Bolivian Andes) and the consequence of reduced groundwaterresources on the quality of water. El Alto city, situated in the Katari basin is most vulnerable to thewater shortage because of climate change and high population growth rate. READ MORE

6. 5. Simulating future wheat yields’ response to climate change and evaluating the efficiency of early sowing in Spain

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Altaaf Mechiche-Alami; [2015]
   Keywords : early sowing; adaptation; climate change; food security; ecosystem analysis; physical geography; Spain; wheat; GEM; Earth and Environmental Sciences;

   Abstract : Global food security is one of the main concerns of this century. Moreover, the increasing negative impacts of climate change on different sectors including agriculture are further expected to exacerbate these challenges. READ MORE
