31. Land-use competition and agricultural greenhouse gas emissions in a climate change mitigation perspective
Sammanfattning : Productive land for food production, bioenergy, or preservation of nature is a limited resource. Climate change mitigation puts additional pressure on land via higher demand for bioenergy to replace fossil fuels and via restrictions on deforestation—two processes that limit the availability of land for food produc- tion, and may thus also raise food prices.

32. The Baltic Sea from the present to future : microbial carbon & nutrient cycling in a changing climate
Sammanfattning : Climate Change is caused by the accelerated increase of anthropogenic greenhousegas emissions to the atmosphere and affects all ecosystems on our planet. A resultof higher CO2 uptake by the oceans as well as an increase of heat trapped in theatmosphere leads to, for example acidification, stratification, sea-level rise, oxygenloss, and temperature increase of the earth’s waterbodies.

33. Water resources in Iceland - Impacts of climate variability and climate change
Sammanfattning : Hydropower is the main source of electricity production in Iceland. In 2005, 80.8% of all electricity was generated by hydropower (7015 GWh). Hydropower production is affected both by variations and changes in discharge. LÄS MER
34. Surface energy exchange and land-atmosphere interactions of Arctic and subarctic tundra ecosystems under climate change
Sammanfattning : The surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. LÄS MER
35. Living in times of climate change. Weather-related understandings, realities, and entanglements among Guarani people in the Bolivian Chaco
Sammanfattning : Since climate change became an issue of public concern worldwide, the weather has attracted increasing attention and come to stand as a common ground for joint action between Indigenous people and governmental and non-governmental actors in the Bolivian Chaco. Despite becoming a common cause, the management of weather through mitigation and adaptation strategies takes place under ontological differences and power imbalances. LÄS MER
