Resumen

Le secteur du bâtiment est un des principaux contributeurs de la crise environnementale mondiale et doit impérativement maitriser ses émissions de gaz à effet de serre (GES). Cette thèse vise à contribuer à l’atteinte de cet objectif en s’intéressant plus particulièrement à la phase d’occupation des bâtiments. Il est nécessaire d’agir lors de cette phase pour respecter un budget carbone défini dès la conception et maintenu sur toute la durée de vie du bâtiment. Cette contribution souligne la nécessité d’une évaluation dynamique dans les processus de prise de décision afin de tenir compte des s

Resumen

Climate change is now more of a reality than ever. Carbon budget provides an upper limit on the amount of carbon that can be emitted, for the earth to be within an accepted temperature rise. People are aware that eating less meat, flying less and reducing product consumption would decrease their emission, but they are not sure on how much less. Existing studies show that people are quite willing to accept the concept of carbon budget but there is no tool that visualises this information at an individual level. This study investigated the features that must be included in a carbon budget tool

Resumen

This thesis explores the factors controlling the distribution of black carbon (BC) in the atmosphere/troposphere and its implications for climate forcing. BC is of great climate interest because of its warming potential. Estimates of BC climate forcing have large uncertainty, in part due to poor knowledge of the distribution of BC in the atmosphere. This dissertation first examines the factors controlling the sources of BC in the Arctic in winter and spring using a global chemical transport model (GEOS-Chem). Emission inventories of BC and wet scavenging of aerosols in the model are updated to

Resumen

Despite climate change being an increasingly important focus of scientific and policy discourse and against a backdrop of rising greenhouse gas emissions, the Russian government has, thus far, failed to commit to an ambitious emission reduction target based on the latest science. For Russia to develop informed, internally consistent and scientifically literate policies, it is important to assess the scale of the challenge and explore implications of different levels of mitigation. To this end, the thesis derives Russia's cumulative emission budgets and generates associated low-carbon pathways

Resumen

Detailed observations of natural and anthropogenic disturbances that alter the forest structure and the distribution of carbon are essential to estimate changes in forest carbon sinks and sources. Remote sensing is one of the primary sources to provide observations of land cover and land-cover change for carbon studies and other ecological applications due to its ability to monitor the Earth’s surface on a regular and continuous basis. However, observations of change are often not attributed directly to an underlying disturbance type and are not well validated, especially in tropical areas.

Resumen

Automotive Original Equipment Manufacturers (OEMs) cause considerable amounts of CO2 emissions over the life cycle of their vehicles. They are thus contributing to global climate change. To stop climate change, all industries, including OEMs, must accomplish a major reduction of CO2 emissions. OEMs report past emissions and receive external support for setting Paris Agreement-compatible reduction targets. Though currently, OEMs do not have access to a methodology that facilitates modelling their future absolute emissions and the leverage of reduction measures at the company level. They are thu

Resumen

Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution. The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans. To be able to model the global carbon cycle and the future climate, it is important to have knowledge of the processes controlling the air-sea exchange of CO2. In this thesis, measurements as well as a model is used in order to increase the knowledge of the exchange p

Resumen

The increase of global average temperature depends linearly on the amount of carbon dioxide that is accumulating in the atmosphere. Consequently, the determination of a temperature target that should not be exceeded, corresponds to an amount of carbon dioxide that can still be emitted. This is referred to as a carbon budget. With the Paris Agreement, a global commitment to such a target exists. The signatories have pledged to hold “the increase in global average temperature to well below 2°C […] and to pursue efforts to limit the temperature increase to 1.5°C”.

Resumen

Cropland management practices have traditionally focused on maximising the production of food, feed and fibre. However, croplands also provide valuable regulating ecosystem services, including carbon (C) storage in soil and biomass. Consequently, management impacts the extents to which croplands act as sources or sinks of atmospheric carbon dioxide (CO2). And so, reliable information on cropland ecosystem C fluxes and yields are essential for policy-makers concerned with climate change mitigation and food security.

Resumen

Quantification of carbon (C) budgets at the landscape or catchment scale is generally achieved using process-based models as scaling tools. Such models require some metric of the exchange surface capability (e.g. Leaf Area Index, LAI) and a set of rate parameters for C processing. The net C exchange is then determined by driving the model with meteorological observations. Regional fields of parameters and drivers may be derived by upscaling site level measurements, constrained using Earth Observation data such as vegetation indices and digital elevation models (DEMs).

A boreal forest wetland (L979) was flooded in 1993 at the Experimental Lakes Area, Ontario to imitate a hydroelectric reservoir and to study the effects of flooding on greenhouse gas production and emission. Flooding initially caused CO₂ and CH4 emission rates to increase and changed the wetland from a small, natural carbon sink to a large source of carbon. The increased production of greenhouse gases in the peatland also caused the majority of the peat to float to the surface creating floating peat islands, within 4 years of flooding. The floating peat islands are a larger sour

Resumen

This study takes as a starting point that climate change must be seen as interrelated with other social, technological, political, and ecological challenges of our times, and that it is closely linked to the local arena of policy and planning. By this, the study is guided by the notion that sustainability transitions are needed to combat climate change. The aim of this study is to explore if and how local carbon budgets can be a tool for municipal governance in facilitating sustainability transitions. Through an analysis of narratives of change and modes of governing, the aim is pursued by stu

Resumen

Bibliography: leaves 179-231.<br>The two main schools of thought regarding the diets of intermediate microphagous clupeids are: A) that they are herbivorous and B) that they are omnivorous, but consume mainly zooplankton. The former view has been employed to explain their abundance in upwelling areas, since their purported ability to efficiently utilise the primary producers shortens the pelagic food chain to 1 or 2 links. The literature concerning the trophic ecology of some commercially important clupeids is reviewed and it is concluded that few are true phytophagists. Most are omnivorous an

Resumen

Understanding the drivers of climate change requires knowledge about the global carbon (C) cycle. Although inland waters play an important role in the C cycle by emitting and burying C, streams and lakes are in general overlooked in bottom-up approached C budgets. In this thesis I estimated emissions of carbon dioxide (CO2) and methane (CH4) from all lakes and streams in a 15 km2 subarctic catchment in northern Sweden, and put it in relation to the total catchment C exchange. I show that high-latitude aquatic systems in general and streams in particular are hotspots for C emission to the atmos

Resumen

Bibliography : pages 178-202.<br>Combined laboratory and field studies were employed to examine the feeding ecology of sardine Sardinops sagax in order to evaluate conflicting hypotheses regarding the trophic position of clupeoids in upwelling ecosystems, and to compare the trophodynamics of sardine with those of the co-occurring anchovy Engraulis capensis. Carbon and nitrogen budget models constructed using data from these studies were used to quantify the effect of particular food environments upon sardine growth. Sardinops sagax is primarily a filter-feeder, with food particles <1230μm tota

Resumen

The research, carried out in 2006 and 2007, concerned the dynamics of the key physiological processes in a vineyard of the Venetian Region. The study allowed a detailed characterization of the energy, hydrological and carbon budget of the vineyard. The measurements have been conducted at different spatial and temporal scales from the leaf, to the canopy, and up to whole the vineyard.The measurements at leaf scale permitted the parameterization of the Farquhar model of photosynthesis to interpret the physiological response of the leaf to the different environment variables.
