1. 1. Mandating transparency on deforestation and ecosystem conversion

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :Moritz Driescher; [2023]
   Nyckelord :sustainability reporting; mandatory disclosure; deforestation; ecosystem conversion; Earth and Environmental Sciences;

   Sammanfattning : The production of eggs, meat, and dairy products in the EU indirectly contributes to deforestation and ecosystem conversion (DEC) in Latin America due to extensive imports of soy for animal feed. This thesis explores under which preconditions the mandatory European Sustainability Reporting Standards for the agriculture and farming sector can increase transparency in the opaque soy supply chains and incentivize reductions of imported DEC.

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

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

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

   Sammanfattning : 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.

4. 3. Analysis of simulated functional diversity in tropical forests: Differences between cultivated and naturally grown secondary forests in Cambodia

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

   Författare :Clarissa Graf; [2023]
   Nyckelord :physical geography; ecosystem analysis; functional diversity; plant functional traits; ecosystem modelling; secondary forest ecosystems; sustainable forest management; LPJ-GUESS; Earth and Environmental Sciences;

   Sammanfattning : Accelerated deforestation represents a major global environmental concern. Over the last decades Cambodia has experienced a drastic decrease in forest cover and measures to halt deforestation have not been as effective as planned. LÄS MER

5. 4. Evaluating forest restoration effects on timing of avian dawn chorus in Ranomafana National Park, Madagascar

   Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

   Författare :Marjolein Pijper; [2023]
   Nyckelord :acoustic monitoring; forest restoration; dawn chorus; avian singing; bird monitoring; automatic recognition;

   Sammanfattning : Monitoring of forest restoration efforts is essential to ensure healthy, self-sustaining tropical rainforests. Passive acoustic monitoring is used to monitor vocal activity of birds, which play a key role in forest ecosystems as seed dispersers. LÄS MER

7. 5. Usability of Sentinel-1 C-band VV and VH SAR data for the detection of flooded oil palm

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

   Författare :Sarah Lee Sienaert; [2023]
   Nyckelord :Geography; GIS; Sentinel-1; SAR; C-band; VV; VH; Oil Palm; Flood; Earth and Environmental Sciences;

   Sammanfattning : Flooding in oil palm plantations in Southeast Asia is a common problem. The oil palm’s habitable range is restricted to lowland equatorial areas, and the high rainfall and degraded landscapes associated with oil palm cultivation leaves oil palm prone to flooding. LÄS MER
