   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Petya Petrowa Kirjazow; [2023]
   Keywords : Earth and Environmental Sciences;

   Abstract : The Janzen–Connell hypothesis states that seedling survival increases with distance from the parent tree, which promotes regular spacing of species within a forest and thus biodiversity. Very few studies have tested this hypothesis in tropical Africa. READ MORE

3. 2. 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

5. 4. Increased carbon sequestration of actively restored tropical forests in Sabah, Malaysia : a comparison of natural regeneration and active restoration

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Johan Engström; [2023]
   Keywords : Degraded tropical forest; Active restoration; Carbon sequestration; Natural regeneration; Enrichment planting; Biomass accumulation;

   Abstract : As restoration with assisted natural regeneration and enrichment planting becomes a more important and popular method to restore ecosystem services and mitigate negative climate effects, these treatments and their effectiveness is heavily debated. There are three main groups of opinions regarding restoration, one is that humans actively need to help nature recover and the second is that nature itself does a better job without our help and the third is somewhere in between.
