EARLY WARNING SYSTEMS :PILOT STUDIES ON EARLY WARNING SYSTEMS : NOTE / BY THE SECRETARIAT
In the target areas, the relationship between natural resources and sustainability returns to the digestible nutrients in plants. The amount of digestible nutrients which can be consumed (grazing capacity) depends upon vegetation types, species composition, the current amount of nutrients and productivity. (...) More concretely, apart from such direct consequences of human interference as cattle grazing, reduced productivity and the diminished luxuriance of species composition/vegetation types, indirect influences are being strongly felt, in terms of physio-chemical changes in soil (soil nutrient degradation, salinization), physical changes (aggregate formation restriction, crust, compaction) and soil erosion. (...) Under the environments, where weather condition (radiation ICCD/COP(7)/CST/7 page 11 intensity, air temperature and humidity) and soil condition (particle size distribution, moisture and nutrient) will be controlled so that the environment in the target area is simulated in the laboratory, the activity of the plant physiology, such as transpiration rate and photosynthesis rate, of the major indicator plant species (e.g.

CALCULATION OF CRITICAL LOADS OF NITROGEN AS A NUTRIENT : SUMMARY REPORT OF THE DEVELOPMENT OF A LIBRARY OF DEFAULT VALUES
RESTRICTED EB.AIR/WG.1/R.108 25 April 1995 Original: ENGLISH ECONOMIC COMMISSION FOR EUROPE EXECUTIVE BODY FOR THE CONVENTION ON LONG-RANGE TRANSBOUNDARY AIR POLLUTION Working Group on Effects (Fourteenth session, Geneva, 10-12 July 1995) Item 4 of the provisional agenda CALCULATION OF CRITICAL LOADS OF NITROGEN AS A NUTRIENT Summary report on the development of a library of default values */ I. (...) The results of the work already done on assessing available data quantifying the input variables to the simple mass balance equation for the calculation of critical loads of nitrogen as nutrient, together with some preliminary conclusions, are presented in the following paragraphs. (...) The increased rates of loss will last for only a small number of years after disturbance, the length of time depending on the rates of recolonization by vegetation: this is rapid, up to one year, on nutrient-rich sites and slow, two to five years (or more in tundra systems), on nutrient-poor sites.

_UK NUTRIENT DATABANK McCance & Widdowson’s Composition of Foods Integrated Dataset (CoF IDS) USER DOCUMENT Introduction The Food Standards Agency (FSA) maintains the UK Nutrient Databank, which contains extensive information on the nutrient content of foods commonly consumed in the UK. (...) The UK Nutrient Databank does not contain values for all nutrients for all foods and therefore the CoF IDS will not have a value for every nutrient for every food. (...) For some nutrients, data which is 'old' and was analysed significantly earlier and on a different sample to the bulk of the nutrients is available.
