- Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper
Sammanfattning : Droughts can have far-reaching and devastating effects on all sectors of society and ecology and future changes to drought and flood patterns are uncertain. This uncertainty has led to a lax response from local officials in dealing with mitigation and adaptation, particularly in Sweden. LÄS MER
2. Spatio-temporal drought characteristics in the Limpopo basin from 1918 to 2018 - A case study based on analysis of the Standardized Precipitation Evaporation Index (SPEI)Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap
Sammanfattning : The identification of the characteristics of drought are of great importance in water resources planning and management. This study explored the characteristics of drought at Limpopo River Basin (LRB) from 1918 to 2018. LÄS MER
- Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap
Sammanfattning : Anthropogenic climate change has increased the frequency of extreme drought events and leads to “hotter” droughts. Topography controls plant available water and site-specific climatic conditions. Drought sensitivity may therefore vary over short distances between wet and dry locations of the landscape. LÄS MER
4. Effects of the 2018 drought on mire productivity in Skogaryd - Evaluation of ground sensors, satellite data and meteorological dataMaster-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap
Sammanfattning : The drought is a complex meteorological phenomenon associated with low precipitation and low water saturation in atmosphere, soils and plants and can has a great effect on aboveground biomass and change the structure and function of the ecosystems. The droughts also are known to reduce the primary and secondary productivity of vegetation. LÄS MER
5. Impact of fire and frost drought events on vegetation greenness and albedo in Subarctic ScandinaviaMaster-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap
Sammanfattning : With climate change, the frequency in climate extremes such as drought, heavy rainfalls, and extreme temperatures is predicted to increase. These extremes can potentially stress and damage vegetation over large areas, leading to altered carbon cycle, vegetation greenness, albedo, and shifted species composition. LÄS MER
