Modelling and assessing surface change impacts on Belgian and Western European climate (MASC). 01/10/2013 - 30/06/2018

Abstract

The overall objective of this project is to study the feedbacks between dimate changes and land surface changes in order to improve regional climate model projections at the decennial scale over Belgium and Western Europe and thus to provide betler climate projections and climate change evaluation tools to policy makers, stakeholders and the scientific community.

Tropospheric ozone effect on tree growth and wood quality and on fluxes in forest ecosystems: a model simulation. 01/10/2006 - 30/09/2007

Abstract

Rising tropospheric ozone (O3) concentrations pose a threat to natural vegetation. Many experiments have been shown O3 to induce growth reduction on trees. Although the physiological mechanisms involved are well known, not much effort has been made to simulate induced growth reduction on trees in a mechanistic way. The aim of this research project is to mechanistically simulate growth reduction on trees, by means of an existing tree growth model and existing datasets from O3 fumigation experiments. The model, called ANAFORE (ANAlysis of FORest Ecosystems), will be validated before the O3-effect on tree growth is added. The latter will be done by incorporation of an O3-module. This module will simulate effects based on calculated stomatal O3-fluxes into the tree. The tree species of interest are common beech (Fagus sylvatica) and Scots pine (Pinus sylvestris).

Interactive effects of enhanced UV-B radiation and CO2 concentration on the gas exchange in a plant crop. 01/10/1999 - 31/12/2000

Abstract

This research will study (1) in detail the effects of UV-B and CO2 on photosynthesis and (2) the penetration of UV-B and PAR in a plant crop (3) the location of UV-B damage correlated to the higth.

    Interactive effects of UV-B and CO2 on different crops 01/10/1999 - 29/04/2000

    Abstract

    Interactive effects of UV-B and CO2 (related to the ozone hole and the greenhouse effect) on different crops were studied in the previous years. The plants (several grass species and white clover) were grown in different greenhouses (0, 82 & 88% of ambient UV-B and ambient and +150 ppm CO2) during summer. Growth, photosynthesis and pigmentation were studied. Special emphasis was on the penetration of UV-B and PAR through the different canopies and differences therein due to the species and to UV-B and CO2-induced canopy changes. The coming months will be used for the further processing and modelling of the data.

      Impact of enhanced UV-B radiation on morphologically and functionally different species, under different C02-concentrations. Analyses and modelling of monocultures using physiological and architectural characteristics. 01/10/1996 - 30/09/1999

      Abstract

      Different varieties of grass, azalea, strawberry and pea will be investigated for differences in response to global change' in conditioned greenhouses. 8 treatments (ambient and enhanced UV-B, C02 concentration and temperature and all combinations) will simulate possible future climate changes. Measurements of growth, gas-exchange, composition, pigmentation as well as modelling of the results will be performed.

        Effects of enhanced UV-B radiation on plants. The link between leaf characteristics, canopy architecture and N-distribution. 30/09/1994 - 30/09/1996

        Abstract

        The effects of enhanced UV-B irradiation on a planophyle (bean) and an erectophyle (rye) vegetation will be studied and modelled by combining data on light penetration, canopy architecture, leaf characteristics and N-distribution.

            Effects of enhanced UV-B radiation on plants. The link between leaf characteristics, canopy architecture and N-distribution. 30/09/1991 - 29/09/1992

            Abstract

            By modelling experimental data on the sensitivity of model vegetations (bean and rye) to increased levels of UV-B, the fundamental importance of several plant parameters (leaf characteristics, canopy architecture and N-distribution) in determining total canopy sensitivity will be assessed.
