Satellite data plus conservation equals better crop yields

SciDev.Net: Combining remote sensing technology with water and soil conservation techniques can help raise crop yields in South Asia, scientists have reported. Satellite data can help identify specific problems on farmlands such as moisture shortage, excessive soil wetness and flood occurrence. Using the data along with appropriate resource conserving technology (RCT) will increase productivity, a study team of researchers reported this month (8 September) in Applied Geography. The study team included...

Sooty Himalayan snow ‘warms climate, alters monsoons’

SciDev.Net: Black carbon landing on snow may be accelerating the melting of Himalayan glaciers more than atmospheric soot or even greenhouse gases such as carbon dioxide (CO2), according to a study. The effects of this carbon, a key component of soot, could change the timing and intensity of the monsoons; increase the chances of downstream floods and reduce farmers' access to irrigation when they most need it, researchers say. The Tibetan Plateau has warmed 1.8 degrees Celsius in the last 50 years and...
