Restoring ecosystems, transforming lives

In areas of the world where local people rely on subsistence agriculture, ecosystem degradation can threaten the lives and resilience of the community. On China’s Loess Plateau in Linxia County, Gansu, this was exactly the case for some time. Though this area was once incredibly fertile, decades of farming and grazing resulted in desertification, erosion and landslides—communities eventually became caught in a cycle of degradation. When agricultural productivity slowed, an increase in poverty, disease and hunger ensued.

The sharp shooters of marine life

The archerfish’s long distance spitting can fire a bug off of a branch and send it down to the water’s surface, and the nearly-blind pistol shrimp uses its gigantic claw to stun its prey with a bubble nearly as hot as the Sun. However, if the archerfish didn’t have keen eyes enabling it to detect an insect against a vegetative background, and if the pistol shrimp lacked its protective eye covers, called orbital hoods, these animals might never have developed the ballistic mechanisms that characterize them.

It’s raining ash! Hallejulah!

While stranded tourists and airline companies curse Iceland’s belching volcano, atmospheric scientists have found a ray of hope in the clouds of ash. In a press conference today, experts from the National Oceanic and Atmospheric Administration (NOAA) said migrating ash plumes are giving scientists a chance to test new atmospheric science models and ash-sampling technology.

Pondering the authority of science

This post contributed by Piper Corp, ESA Science Policy Analyst Who says we have to listen to scientists? When President Obama vowed in his inaugural address to “restore science to its rightful place,” where exactly was he talking about? The thou-shalts and self-evident truths on which Americans base so many decisions have little to say about consulting sound science. Still,…

Field Talk: Termites enrich the soil in East Africa

Vertebrate fertilizer is not the only source of nutrients in the soils of East African savannahs, at least according to a study recently published in the journal Ecology. Alison Brody from the University of Vermont and colleagues found that termites actually had more of an effect on the fruiting success of Acacia trees in Kenya than did dung and urine deposition from ungulate herbivores, such as zebras and gazelles.

Climate change from a population perspective

Numerous policy discussions have emerged regarding the impact of climate change on humans; however, this interaction is a two-way street, said scientists in a Washington, DC briefing last Friday. That is, how will climate change impact human health and how will population growth affect factors like carbon emissions? The short answer is that they are closely connected; the longer answer is that scientists are currently trying to flesh out the exact effects and viable options for a future with global climate change, human expansion and urbanization.
