Iv. environmental stress factors.
Relationship between forest condition and environmental stress factors.
Evaluations of level II data focused on:(i) present deposition;(ii) dynamic modelling of past and future soil solution concentrations of nitrate, sulphate and aluminium;(iii) carbon sequestration in forests; and(iv)ground vegetation diversity and its relation to environmental stress factors.
Uncertainties in the derivation of environmental stress factors.
From the scientific point of view,the assessment of additional parameters characterizing the level I plots would provide valuable information necessary to make further attempts to evaluate relationships between crown condition and environmental stress factors.
Ii. influence of atmospheric deposition and other environmental stress factors on forest ecosystems.
Several countries will undertake, on a voluntary basis, additional assessments on a limited number of level II plots to derive relationships between stand structure andfloristic biodiversity, and their relationships to environmental stress factors.
The skin is therefore less sensitive to daily environmental stress factors, such as UV light and air pollution.
Assessment of forest biodiversity in relation to air pollution and other environmental stress factors;
For the calibration of external data sets on environmental stress factors at the level I plots, data collected on level II plots should be used.
Assessment of forest biodiversity in relation to air pollution and other environmental stress factors;
Careful scientific considerations of all environmental stress factors, including toxicological interactions and climate change interactions with the chemical proposed for listing in the hazard assessment within the risk profile developed in accordance with Annex E to the Convention.
Ground vegetation and forest biodiversity in relation to air pollution and other environmental stress factors;
In multivariate statistics conducted with level I as well aswith level II or external data, correlations between crown condition and environmental stress factors have been demonstrated(see chap. II, sec. D and chap. IV). Crown condition is assessed in 5% defoliation steps and grouped into five defoliation classes of uneven width.
Evaluations of level II data focused on present deposition, critical loads and critical load excess for nitrogen, acidity andheavy metals, as well as on ground vegetation diversity and its relation to environmental stress factors.
Furthermore, the strength of correlations between crown condition and environmental stress factors is influenced by the quality of the assessed data.
The assessment of biotic stress factors(pests, diseases, fungi, etc.) should be improved in order to include more reliable information on environmental stress factors into statistical analyses.
An attempt to derive empirical relationships between forest condition and environmental stress factors including air pollution.
Such an analysis requires the felling of sample trees, which was carried out in thebuffer zone of 46 level II plots. The large data sets of the level II plots also enabled first attempts to investigate the influence of environmental stress factors, including air pollution, on the growth of the trees.
IFAD's support for such research aims at the generation of technologies that allow traditional crops/commodities produced by resource-poor farming systems to transcend conventional threshold levels of yield,improve tolerance to environmental stress factors as well as resistance to pests and diseases that currently undermine the productive capacity of poor smallholders.
However, there are two other key factors that contribute to environmental stress: poverty and high population growth.
Increasing the body's resistance to adverse psycho-emotional, social,occupational, environmental, climate and other stress factors;
Statistical evaluations indicate that there is a complex system of environmental conditions and stress factors that may act sequentially, concurrently, synergistically or cumulatively on forest stands and thus lead to different types of ecological reactions by the trees.
However, population pressures are contributing factors to environmental stress.
Ideal for the skin affected by environmental factors, stress or sun exposure.
Environmental factors, stress, chemical treatments and burden on the hair tend to worsen its condition.
Environmental influences: Factors such as stress and toxic substances can lead to hair loss.
Schizophrenia can be triggered by a variety of environmental factors, including significant stress, intensely emotional situations, and disturbing or uncomfortable experiences.
Social and occupational stress and changes are also included as environmental factors in the societal model.
Environmental and social factors may include family stress, peer pressure, increasing urbanization, absence of employment, work which is emotionally unsatisfying, and pressures of everyday life.
