2. 1. Fungal disease dynamics, genetic variation and biodiversity-yield relationships : — a study along a gradient of coffee management in southwestern Ethiopia

   Author : Beyene Zewdie Hailu; Kristoffer Hylander; Ayco J.M Tack; Jacques Avelino; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Armillaria root rot; biodiversity; biodiversity-yield trade-offs; coffee; Coffea arabica; coffee berry disease; coffee leaf rust; coffee wilt disease; coffee yield; genetic composition; genetic diversity; hyperparasite; management intensity gradient; southwestern Ethiopia; Plant Ecology; växtekologi;

   Abstract : Intensification of agricultural systems is a major threat to the associated biodiversity and could also affect the dynamics of pests and pathogens. One such system that is currently under an intensification trajectory is the production of Arabica coffee. READ MORE

4. 2. Explaining Agricultural Yield Gaps in Cameroon

   Author : Yengoh Genesis Tambang; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; agricultural management; agricultural production; Cameroon; crop suitability; food security; small-scale; sub-Saharan Africa; sustainable intensification; vulnerability; yield gaps;

   Abstract : Popular Abstract in Swedish Ökad livsmedelsproduktion utgör ett viktigt steg för att uppnå livsmedelssäkerhet i Kamerun. Under det senaste halvseklet har ökningen av produktionen i huvudsak uppnåtts genom ökad uppodling. READ MORE

5. 3. Renewable Energy and Nutrient Valorization from Anaerobic Digestion : Resource-Efficient Solutions

   Author : Sandra Carlos-Pinedo; Zhao Wang; Ola Eriksson; Shveta Soam; Henrik Wenzel; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid-state anaerobic digestion; methane yield; digestate; systems analysis; modelling; life cycle assessment; Torrötning; metanutbyte; biogödsel; systemanalys; modellering; livscykelanalys;

   Abstract : This thesis presents a comprehensive analysis aimed at understanding process performance, methane yield, and key influencing factors within the context of solid-state anaerobic digestion (SS-AD). SS-AD is used to treat organic material with high solids content, which can be challenging to address by alternative methods. READ MORE

6. 4. The relationship between climate, disease and coffee yield: optimizing management for smallholder farmers

   Author : Biruk Ayalew Nurihun; Ayco J. M. Tack; Kristoffer Hylander; Ivette Perfecto; Stockholms universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Agroforestry; Arabica coffee; climate change; fungal disease; host-hyperparasite interaction; insect pest; minimum temperature and maximum temperature; shade cover; shade tree species; smallholder farmers; yield; Ecology and Evolution; ekologi och evolution;

   Abstract : Climate change and diseases are threatening global crop production. Agroforestry systems, which are characterized by complex multispecies interactions, are considered to provide nature-based solutions for climate change mitigation and pest and disease regulation. READ MORE

7. 5. GETTING MORE OUT OF THE AFTERLIFE

   Author : Derek Diener; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MFA; remanufacturing; steel; company-level; Product EoL management; material efficiency;

   Abstract : Material intensity related to product consumption has become part of societal discourse and reducing it has become a priority of some industrial actors. Focusing on product end-of-life (EoL) is one approach that many companies and research entities have taken to identify and enact material intensity reductions. READ MORE
