Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER
- Detta är en avhandling från Department of Physical Geography and Ecosystem Science, Lund University
Sammanfattning : This thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. LÄS MER

Sammanfattning : Wind erosion is a serious threat to soil resources as it causes depletion of the fine fractions that may result in a less fertile soil. Wind erosion encompasses several processes of which many are related to climate variables. To date, there is little work performed on how wind erosion relates to climate and climate change. LÄS MER
4. Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological DataDetta är en avhandling från Lund University, Faculty of Science, Department of Physical Geography and Ecosystem Science
Sammanfattning : The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. LÄS MER
5. Life paths through space and time: Adding the micro-level geographic context to longitudinal historical demographic researchDetta är en avhandling från Lund University, Faculty of Science, Department of Physical Geography and Ecosystem Science
Sammanfattning : Historical demographic research is central to understanding past human behaviours and traits, such as fertility, mortality and migration. An essential part of historical demography is conducting longitudinal analyses at the micro-level, which involves the detailed follow-up of individuals over long time periods throughout their lives.
