Three plant researchers describe in this book how plants emerged via the fusion of several different types of simple prokaryotic organisms and, through algae, evolved into land plants. During their evolution, they survived global ice ages, violent volcanic eruptions, and collisions with celestial bodies. The authors follow the development of landplants along various paths- some of which have ended

This report presents findings from a case study on food sharing in Utrecht conducted within the CULTIVATE project (Co-designing Food Sharing Innovation for Resilience, https:// cultivate-project.eu/), funded by the EU Horizon Research and Innovation Programme (GA#101083377). It contributes to Task 3.1 in Work Package (WP) 3, examining the economic, social, and environmental dimensions of food shar

The last decades have shown increased nitrogen leeching from soil to water recipients. This is in Sweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and the declining extent of wetlands. The accumulated amount of nitrogen in water doesn’t only make it unsuitable for use by humans and cattle, but also decreases the biological diversity as well as negatively

The relationship between field measurements of vegetation in a semi arid region and NDVI from the 1 km NOAA AVHRR was investigated within this study. The Hoanib catchment in the northwestern Namibia was chosen as study area. The field measurements were carried out during the month of February 1999. Different NDVI values and combinations of NDVI were used and it was found that the integrated NDVI u

At the end of August 1999, the local government council of Malmö city decided that the area known as Kvarteret Bilen would be made available for the European Housing Exhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80 hectars and includes the western parts of the Western Harbour area (Västra hamnen) of Malmö. Kvarteret Bilen as a whole, but especially the western sections

The aim with this thesis was to investigate the land surface model used in DAYCENT. Through comparing the simulated soil moisture and soil temperature results with observed data, at the depth of 30 and 60 cm at the Demokeya site in semiarid Sudan, it was possible to evaluate the model. The ecosystem model uses soil texture data, land management information, and daily weather data to simulate plant

Vomb meadows is an area well knows for its rich bird life. During the 19:th century until mid 20:th century, the meadows were flooded annually in order to increase the hay yield. The river Klingavälsån situated along the west side of the meadows, used to be a shallow river, meandering across the landscape. In the 1940’s the river was straightened and made deeper. This was done in purpose of draini

Only 40% of the total CO2 emitted by human activities and natural sources remain in the atmosphere, since the rest is taken up by plants and oceans. In particular temperate and boreal forests are usually significant sinks of carbon, even if they are very susceptible ecosystems and they might turn into sources in consequence of the predicted temperature increase. That is one of the reasons why a ne

Fluxes of sensible heat and latent heat were calculated above fields of barley and wheat in Ilstorp, using a gradient profile approach. Gradient Richardson’s number was used as the stability parameter, and it was shown that atmospheric stability varies both with time of the day and wind speed. Temperature and wind profiles were studied, and it was possible to detect a rise in the active surface in

To create an environmentally friendly road transport system is one of the main policy goals of the Swedish National Road Administration (Vägverket). In order to achieve this goal Environmental Impact Assessment (EIA) has been introduced at all levels of road planning process at Vägverket. The role of EIA is to provide decision-makers with information about the possible consequences of a planned fa

This essay examines how different levels of employment protection can affect labour demand for workers with different characteristics. This issue is analysed theoretically utilising the theory of fixed costs of labour and insider-outsider theory. The main conclusion from this analysis is that strict employment protection can be expected to have a disproportionately negative impact on the demand fo

Latest research confirmed that plant matter can also produce a non negligible amount of the greenhouse gas methane under aerobic conditions. These findings have led to discussions and controversy within the research community. While KEPPLER ET AL. (2006) as one of the first researchers published results supporting this hypothesis others like DUECK ET AL. (2007) refuted these results within their e

The area around Lake Vänern in western Sweden is an exposed area for flooding. It has since the measurements started in the 1900th century been flooded repetitively. In the coming 100 years the water level is supposed to increase between 1-3 meters. This will most probably lead to worse and more regular floods in the area. There area around Lake Vänern is very densely populated and it will most pr
