Leading water scientists warn of risks in shift to monoculture crops, tree plantations

(University of Saskatchewan) Conversion of large swaths of land to uniform tree plantations and single-crop species may lead to unintended consequences for the water cycle, putting ecosystems at greater risk for fires, floods, droughts and even hurricanes, warns a think-tank group of almost 30 water scientists from 11 countries.

40% of O’ahu, Hawai’i beaches could be lost by mid-century

The reactive and piecemeal approach historically used to manage beaches in Hawai’i has failed to protect them. If policies are not changed, as much as 40% of all beaches on O’ahu, Hawai’i could be lost before mid-century, according to a new study.

Ancient human footprints in Saudi Arabia give glimpse of Arabian ecology 120000 years ago

Using high resolution paleoecological information obtained from fossilized footprints, a new study presents ~120 thousand-year-old human and animal footprints from an ancient lake bed in northern Arabia. These findings represent the earliest evidence for humans in this part of the world and show that human and animal movements and landscape use were closely linked.

Venus’ ancient layered, folded rocks point to volcanic origin

(North Carolina State University) An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet’s geological history.

Siberia’s permafrost erosion has been worsening for years

The Arctic is warming faster than any other region on the planet. As a result, permafrost that is thousands of years old is now being lost to erosion. As measurements gathered on the Lena River show, the scale of erosion is alarming.

Global study reveals time running out for many soils, but conservation measures can help

Researchers found more than 90 per cent of the conventionally farmed soils in their global study were thinning, and 16 per cent had lifespans of less than a century. These rapidly thinning soils were found all over the world, including countries such as Australia, China, the UK, and the USA.
