Evergreen: Vitalisatie van oud Amsterdam
Woningbouw project in het centrum van Amsterdam, waarbij tuinieren en wonen gecombineerd worden.
Dynamics of rainwater lenses on upward seeping saline groundwater
Fresh water is generally a limited resource in coastal areas which are often densely populated. In low-lying areas, groundwater is mostly saline and both agriculture and freshwater nature depend on a thin lens of rainwater that is formed by precipitation surplus on top of saline, upward seeping groundwater. Understanding the dynamics of such lenses...
A clash of plants : Vegetation succession and its interaction with permafrost dynamics in the Arctic lowland tundra
Arctic ecosystems have been affected by severe climate change during the last decades. The increase in temperature in the Arctic has been almost double of the global rate of warming since the beginning of the 20th century. Like other ecosystems in the high latitude region, Arctic tundra appears to be extremely sensitive to the continuous warming of...
Turbulent exchange of energy, momentum, and reactive gases between high vegetation and the atmospheric boundary layer
This thesis deals with the representation of the exchange of energy, momentum and chemically reactive compounds between the land, covered by high vegetation, and the lowest part of the atmosphere, named as atmospheric boundary layer (ABL). The study presented in this thesis introduces the roughness sublayer (RSL), the layer just above the tall vege...
Dunes, above and beyond : The interactions between ecological and geomorphological processes during early dune developme...
Coastal dunes occur along the sandy shores of most continents where they serve as coastal defence against flooding, provide areas for recreation, store drinking water and harbour unique biodiversity. Coastal dunes and the services they provide are threatened by climate-induced sea-level rise. This threat may be mitigated by the spontaneous formatio...
Meer biodiversiteit met brede groene dijken? : een verkenning van de vegetatie op de Waddenzeedijken
In dit rapport worden de vegetaties op het buitentalud van de brede groene Waddenzeedijken in Duitsland en Denemarken vergeleken met de vegetaties op het buitentalud van de gangbare Waddenzeedijken in Nederland, met als doel om inzicht te krijgen in de mogelijke meerwaarde van het Brede Groene Dijk-concept voor biodiversiteit, en voor vegetatie in ...
Large herbivores as a driving force of woodland-grassland cycles : the mutual interactions between the population dynami...
This thesis examines the mutual interactions between the population dynamics of large herbivores and wood-pasture cycles in eutrophic wetlands. Therefore, habitat use and population dynamics of large herbivores, the effects of large herbivores on vegetation development, and the mutual interactions between vegetation development and herbivore popula...
Ecohydrologische systeemanalyse Liefstinghsbroek
Het Lieftinghsbroek in Oost-Groningen bestaat uit gevarieerd loofbos met enkele schraalgraslandjes in het dal van de Ruiten Aa. Het gebied is aangewezen voor Natura 2000 habitattypen bos en schraalland en is tevens bosreservaat. Om meer inzicht te krijgen in het effect van vernattingsmaatregelen in de directe omgeving van het gebied is een ecohydro...
Hydrological controls on salinity exposure and the effects on plants in lowland polders
The Dutch lowlands may be subject to salinization, through saline upward seepage and increased salt concentrations in the surface water, which may affect agriculture and nature areas with floating fens. A simple approach was proposed to estimate root zone salinization in areas with fresh water lenses that float on upward seeping saline groundwater,...
Resilience of Amazonian forests : the roles of fire, flooding and climate
The Amazon has recently been portrayed as a resilient forest system based on quick recovery of biomass after human disturbance. Yet with climate change, the frequency of droughts and wildfires may increase, implying that parts of this massive forest may shift into a savanna state. Although the Amazon basin seems quite homogeneous, 14% is seasonally...
