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.

Tier 1 disaggregates soils into "nutrient rich" and "nutrient poor" areas, whereas higher-tier methods can further disaggregate into different peatland types, soil fertility or tree species

Emphasis is placed on the maintenance of sustainable and diverse farming systems that not only ensure the maintenance of ecosystem functions such as nutrient cycling and water quality but also ensure risk management from threats such as drought, pest and disease.

In March 2013, for example, algae contamination in the Santa Lucía basin, apparently caused by nutrient pollution, affected the colour and taste of drinking water in Montevideo, greatly increasing public concerns about the effects of agricultural pollution on water quality. 24.
