Soil Erosion
While knowledge of how soil erosion occurs and how to control it is firmly established, more research is needed on how to measure soil loss rates and budget for measures to reduce them - remain under debate. Indeed, there is disagreement over whether erosion turns soil into a source or sink for carbon emissions, as well as rival formulas to assess the relationship between the size of raindrop splashes and the likelihood that they detach soil particles and remove them from the landscape.
Still, evidence is clear that soil erosion rates on conventionally ploughed agricultural land or intensively grazed pasturelands are notably greater than erosion under native vegetation - and much higher than soil formation rates - implying that we are depleting a non-renewable resource.
