According to a new study, almost 36 billion tons of soil is lost every year due to water, and deforestation and other changes in land use make the problem worse. The study also offers ideas on how agriculture can change to become a part of the solution from being part of the problem.

Northeast Farmers Weigh Warming Climate, Drenched Fields
Farmers in the Northeast are adapting to longer growing seasons and warming climate conditions – but they may face spring-planting whiplash as they confront fields increasingly saturated with rain, according to a research paper published in the journal Climatic Change.
Exposure to Larger Air Particles Linked to Increased Risk of Asthma in Children
Researchers at The Johns Hopkins University report statistical evidence that children exposed to airborne coarse particulate matter — a mix of dust, sand and non-exhaust tailpipe emissions, such as tire rubber — are more likely to develop asthma and need emergency room or hospital treatment for it than unexposed children.
NASA Sees Tropical Storm Kai-Tak Moving Over the Philippines
NASA's Aqua satellite provided infrared imagery of Tropical Storm Kai-Tak that revealed the western side of storm had moved into the southern and central Philippines. Infrared data revealed very cold cloud top temperatures with the potential for heavy rainfall.
La exposición a las partículas del aire, de mayor tamaño, vinculadas con un mayor riesgo de asma en niños
Investigadores de la Universidad Johns Hopkins informan que hay evidencia estadística de que los niños expuestos a partículas gruesas suspendidas en el aire, una mezcla de polvo, arena y emisiones de vehículos que no son del escape sino, por ejemplo, la goma de los neumáticos, tienen más probabilidades de desarrollar asma y necesitan tratamiento hospitalario u hospitalario más que niños no expuestos
More frequent fires reduce soil carbon and fertility, slowing the regrowth of plants
Frequent burning over decades reduces the amount of carbon and nitrogen stored in soils of savanna grasslands and broadleaf forests, in part because reduced plant growth means less carbon being drawn out of the atmosphere and stored in plant matter. These findings by a Stanford-led team are important for worldwide understanding of fire impacts on the carbon cycle and for modeling the future of global carbon and climate change.
