Bokkapitel (refereegranskat)abstract
- Anthropogenic land-cover change (ALCC) is one of the few climate forcings for which the net direction of the climate response over the last two centuries is still not known. The uncertainty is due to the often counteracting temperature responses to the many biogeophysical effects and to the biogeochemical versus biogeophysical effects. Palaeoecological studies show that the major transformation of the landscape by anthropogenic activities in the southern zone of the Baltic Sea basin occurred between 6000 and 3000/2500 cal year BP. The only modelling study of the biogeophysical effects of past ALCCs on regional climate in north-western Europe suggests that deforestation between 6000 and 200 cal year BP may have caused significant change in winter and summer temperature. There is no indication that deforestation in the Baltic Sea area since AD 1850 would have been a major cause of the recent climate warming in the region through a positive biogeochemical feedback. Several model studies suggest that boreal reforestation might not be an effective climate warming mitigation tool as it might lead to increased warming through biogeophysical processes.

Analys av geografiska data

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- I detta kapitel i boken Geografisk information Behandling beskrivs och behandlas metoder för hur geografisk data analyseras. Kapitlet omfattar såväl geografisk teori som exempel på tillämpningar. Geografisk informationsbehandling baseras på insamling, lagring, analys och visualisering av geografiska data. Denna indelning utgör också grunden för bokens disposition. Boken är i första hand avsedd för introducerande kurser vid universitet och högskolor men vissa delar är lämpliga även på avancerad nivå. Den är också utmärkt för yrkesverksamma inom GIS som vill öka sina teoretiska kunskaper.Boken innehåller både teoretiska och praktiska delar, där de senare beskriver tillämpningar som exempelvis samhällsplanering, miljöövervakning och kommersiella tjänster. I insamlingsdelen beskrivs hur man anger en position genom att koppla ett koordinatsystem till jordytan. Därefter beskrivs de vanligaste metoderna att samla in geografiska data som satellitbaserade positioneringssystem, flygfotografering, satellitbaserad fjärranalys och laserskanning. Lagringsdelen behandlar hur dessa data lagras i databaser och distribueras via webben. Analysdelen innehåller beskrivningar av de vanligaste analysmetoderna samt kvalitetsfrågor. Resultatet av en geografisk analys visualiseras oftast i form av kartor, vilket är temat för den sista delen av boken.Denna sjunde upplaga har uppdaterats med nya aktuella tillämpningsexempel. Dessa är i denna upplaga beskrivna tillsammans med de teoretiska beskrivningarna för att stärka kopplingen mellan teori och tillämpningar. Dessutom har beskrivningen av webbtillämpningar utökats och utgör nu ett eget kapitel, och även texten om webbvisualiseringar har stärkts i kartografikapitlet. Vidare har det tillkommit beskrivningar av nya mättekniker samt texter om lagring, analys och visualisering av 3D geografiska data.

Bokkapitel (populärvet., debatt m.m.)abstract
- The use of coal, oil and gas, and land use change, has caused emissions of carbon dioxide which equals to about 550 billion tons of carbon. Half of these have accumulated in the atmosphere, which warms our climate with profound effects on natural and human systems. The other half has been absorbed by the oceans and the biosphere. Climate change affects the strength of these ‘ carbon sinks’. Knowledge about their future capacity is important for informed action on climate stabilisation. MERGE’s research on a new generation of climate models aims for a greater understanding of vegetation, climate and climate change

Land Type Categories as a Complement to Land Use and Land Cover Attributes in Landscape Mapping and Monitoring
- 2015
-
Ingår i: Land Use and Land Cover Semantics. - Boca Raton : CRC Press. - 9781482237399 ; , s. 171-190
-
Bokkapitel (refereegranskat)abstract
- The purpose of land cover and land use descriptions varies, and this influences how these concepts are perceived in different contexts. The increasing need for spatial data for multipurpose monitoring and modeling also increases the demands for compatibility, repeatability, detail, and well-documented criteria. We suggest that threshold values along a continuous scale can be used to create nominal classes for a common conceptual framework. However, the exact values of these thresholds need to be based on well-defined functional and systematic criteria. Ecological and environmental gradients are often mosaic and complex, and several types of land use may coexist at the same site. In reality, land use can be seen as a “shifting cloud” of activities varying in both time and space. We advocate the use of strict definitions of land cover as physical structures and land use as human activities, which raises the need for a complementary concept, which we call “land type,” with stable threshold values based on mutually exclusive functional criteria. Such functional criteria often put clear limits to what spatial resolution is appropriate, since the suitability for a certain purpose (e.g., agriculture or forestry) is determined by the user of the land, rather than by the independent observer. Our example of land type categories comprises a two-level hierarchical classification with seven main types and altogether 28 subtypes. As an example, we discuss the overlapping Swedish definitions of forest and arable land. The criteria that define our main land types are less dependent on how the area is managed at a specific moment in time, and they are therefore less sensitive to short-term variation. The land types define the limits for what land cover and land use can be expected at a certain site, given, for example, ground conditions, water, or artificial structures. Since such land types need to incorporate functional and qualitative understanding and interpretation, human visual interpretation is needed, whereas automated remote sensing methods are suitable mainly for the structural aspects of land cover.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Synthetic aperture radar (SAR) provides large coverage and high resolution, and it has been proven to be sensitive to both surface and near-surface features related to accumulation, ablation, and metamorphism of snow and firn. Exploiting this sensitivity, SAR polarimetry and polarimetric interferometry found application to land ice for instance for the estimation of wave extinction (which relates to sub surface ice volume structure) and for the estimation of snow water equivalent (which relates to snow density and depth). After presenting these applications, the Chapter proceeds by reviewing applications of SAR polarimetry to sea ice for the classification of different ice types, the estimation of thickness, and the characterisation of its surface. Finally, an application to the characterisation of permafrost regions is considered. For each application, the used (model-based) decomposition and polarimetric parameters are critically described, and real data results from relevant airborne campaigns and space borne acquisitions are reported.
