1. 21. Local perceptions of changes in ecosystem services and climate : case study in Ecuadorean Sierra

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Anna Sundqvist; [2018]
   Nyckelord :traditional ecological knowledge; ecosystem services and goods; climate change;

   Sammanfattning : Anthropogenic-induced land-use and land-cover change is a threat to biodiversity and ecosystem services, and contribute to global climate warming. Forests are essential in the climate system and store a large part of the global carbon. LÄS MER

3. 22. Vegetation history and human-environment interactions through the late Holocene in Konar Sandal, Kerman, SE Iran

   Master-uppsats, Linköpings universitet/Institutionen för tema

   Nyckelord :Agro-pastoralism; Climate Change; Geochemistry; Palynology; pollen analysis; palaeoecology; peat; Konar Sandal; Jiroft; Iran; Middle East; Vegetation history; Environmental history; Saharo-sindian; pseudo-savanna; Archaeology; Jiroft culture;

   Sammanfattning : The Jiroft valley, in southeastern Iran, was an important agricultural centre since the Early Bronze Age (3rd millennium BCE). The valley is characterized by harsh environmental settings: hot climate with poor rainfall. However, more optimal conditions may have prevailed earlier that supported ancient settlements. LÄS MER

4. 23. What is the Wonder? An ethnography of 'rewilding' at the iSimangaliso Wetland Park, KwaZulu-Natal, South Africa

   Nyckelord :land reform; conservation; indigenous people; traditional authority; cultural theory; Social Sciences;

   Sammanfattning : ‘Rewilding’, or the return of degraded lands to a state of ‘wilderness’, is a bold attempt to resolve the world’s ecological challenges. It however does not address the division between nature and society, which lies at the core of the issues. LÄS MER

5. 24. APRIL Ecosystem Restoration Project: A sustainable model for Indonesian peatlands?

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Michael Ceruti; [2016]
   Nyckelord :Sustainable development; Ecosystem Restoration Concession; peatland degradation; restoration; conservation; Kampar Peninsula; Indonesia;

   Sammanfattning : The growth in global population and the unsustainable business as usual model adopted by private companies in managing land, are causing huge pressures on Indonesian natural ecosystems. The widespread peatland deforestation and degradation affecting Indonesia has been the leading cause of biodiversity loss, decrease of vital ecosystem services, land subsidence, fires and increased impoverishment of local communities.

7. 25. Impact of Crop Diversity, Fertilization and Legumes on Soil Organic Carbon in Grasslands

   Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

   Författare :Kristina Witzgall; [2016]
   Nyckelord :Soil organic carbon; soil quality; agricultural productivity; perennial production grassland; fertilization; crop diversity; soil carbon; Earth and Environmental Sciences;

   Sammanfattning : Agricultural soil quality is decreasing as a result of the expansion and intensification of agriculture. A key indicator of soil quality is soil organic carbon (SOC) which is degraded when land is converted from natural to cultivated systems and subject to intensive agricultural land use, reflecting reduced soil fertility and productivity.
