On the other hand, climate change scenarios estimate that the soil loss rates may increase by 10 - 15 % by 2050 due to an analogous increase of rainfall - induced erosion in Europe.

As soil erosion has huge impacts on ecosystems, food production, drinking water, carbon stocks and biodiversity, the EU has called for quantitative assessments of soil rates at EU level, and put soil protection at the heart of its environmental agenda.

The solution was to compare the amount of confirmed craters of different sizes, calculate the expected frequency of the impacts on the basis of the known probabilities, and combine this information to infer the rates of erosion.

The life span of a crater depends on the rate of erosion and its size.

On «healthy» coral reefs, bioerosion rates can be high, but more carbonate is typically produced than is lost to biological erosion.

In their investigation, Udo and Takeda (ibid) determined beach - loss rates of 49 % for an SLR of 0.3 m and 93 % for an SLR of 1.0 m. Yoshida et al. (2013), had projected future beach erosion using the Bruun rule (Braun, 1962) due to SLR for SRES A1B to have the greatest effect on beach erosion.

Eventually, however, terrestrial red and green algae and the first lichens developed on land and the final big rise in oxygen may have been caused by the «greening of the continents from around 800 million years ago,» when these simple early lifeforms on land steadily spread and broke down rocks that sustained a higher rate of erosion and led to the release of more nutrients into the oceans that stimulated even more photosynthesis by more newly evolved algae as well as older cyanobacteria (Nick Lane, New Scientist, February 10, 2010).
