Nevertheless, our understanding of the impact of humans on the natural ...

Even in the absence of sea-level rise, deltas are increasingly vulnerable to coastal hazards as declining sediment supply and climate change alter their sediment budget, affecting delta morphology and possibly leading to erosion1,2,3. However, the relationship between deltaic sediment budgets, ...
Active erosion of the riverbed and coarsening of surficial sediments were observed in the middle and lower reaches. Fining of suspended sediments was identified along the river, which was counteracted by downstream erosion. Along the 700-km-long Three Gorges Reservoir, which retained 80% of the ...
Coastal dynamics in the Pechora Sea under technogenic impact The coasts of Barents and Kara Seas which are composed of unconsolidated deposits have poor erosion resistance qualities. In natural conditions such coasts may retreat with a rate of 1 to 2 m a year. Under the influence of human act...
animals or places has an impact on the ecosystem, whether it’s the ability of spiders to continue trapping and consuming their insect prey or minimizing high elevation habitat erosion. (Hopefully your fear of this election will lead you to vote, which will certainly have an impact on the ...
Without pesticides, food production would be lower, and larger cultivated farm areas would be necessary to produce the same amount of food, which would impact the wildlife habitat. More frequent cultivation of the fields would be increase soil loss due to erosion, too. Knutson et al. [7] ...
Human impact and soil erosion during the last 5000 yrs as recorded in lacustrine sedimentary organic matter at Lac d'Annecy, the French Alps Sedimentary organic matter has been systematically studied in an eight-metre long core from the centre of the Petit Lac (Annecy, French Alps). The paly...
impact of the bill on the rule of law and human rights. In this blog, I argue that this order puts the UK on par with Russia and Poland, which have used domestic law to prevent compliance with their international obligations under the European Convention on Human Rights (ECHR). I show ...
In the Rif Mountains, increased influx of carbonates (Ca) in the sedimentary records indicates enhanced soil erosion coincident with the reduction in tree cover. In the Middle Atlas, reduced forest cover is linked to geochemical evidence for mining and metallurgy of lead (Pb), copper (Cu) and...
