Latest Erosion Stories
By Valarie Allen, The Creston News Advertiser, Iowa Jun. 18--What worked and what didn't was the topic of a tour Thursday directed by Union County Conservationist with Natural Resources and Conservation Paul Goldsmith.
Indigenous peoples have contributed the least to world greenhouse gas emissions and have the smallest ecological footprints on Earth. Yet they suffer the worst impacts not only of climate change, but also from some of the international mitigation measures being taken.
Video images from the St. Clair River bottom show no evidence of erosion causing water levels on Lakes Michigan and Huron to drop, scientists working for a U.S.-Canadian advisory group said Thursday.
The first soil moisture maps with a spatial resolution of one km are available online for the entire southern African subcontinent. As soil moisture plays an important role in the global water cycle, these maps, based on data from ESAâ€™s Envisat satellite, will lead to better weather and extreme-event forecasting, such as floods and droughts.
A single drop is harmless, but when billions of raindrops from a cloudburst fall on bare soil they strike like billions of tiny hammers, dislodging tons of soil per acre which is carried away by surface runoff.
Mother Nature may be a force, but nothing like humans when it comes to causing erosion, says a Syracuse University scientist. Humans cause erosion at a rate 10 to 15 times faster than any natural process.
The United Nations used World Environment Day on Monday to warn that the growth of deserts was a growing obstacle to ending poverty and a threat to peace.
By Hamid Ould Ahmed ALGIERS (Reuters) - The United Nations used World Environment Day on Monday to warn that land turning to desert is a growing obstacle to ending poverty and a threat to peace.
One of the paradoxes of recent explorations of the Martian surface is that the more we see of the planet, the more it looks like Earth, despite a very big difference: Complex life forms have existed for billions of years on Earth, while Mars never saw life bigger than a microbe, if that.
Glaciers, rivers and shifting tectonic plates have shaped mountains over millions of years, but earth scientists have struggled to understand the relative roles of these forces and the rates at which they work.
Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...
