The sensitivity of Amazon rainforests to dry?season droughts is still poorly understood, with reports of enhanced tree mortality and forest fires on one hand, and excessive forest greening on the other. Here, we report that the previous results of large?scale greening of the Amazon, obtained from an earlier version of satellite derived vegetation greenness data ? Collection 4 (C4)

A drought that happens once in a hundred years had little negative or positive effect on the Amazon rainforest according to this study led by Arindam Samanta from Boston University. Its results are different from 2007 IPCC report which stated that 40 percent of the Amazon rainforest was threatened by climate change.

On 1 April 1960, the world's first weather satellite, the Television Infrared Observation Satellite 1 (TIROS 1), was launched from
Cape Canaveral, Florida, into a 99-min orbit at an altitude of about
725 km. The cylindrical (1.1-m diameter, 0.48-m tall), 120-kg
spacecraft was spin-stabilized, rotating between 8 and 12 times per
min.

Thanks to a little help from researchers equipped with satellite imagery, farmers in Raj Samadhilyia, a tiny village in Gujarat, have been able to do a better job of capturing, managing, and using the precious water provided by scanty rains.

Precision agriculture comprises a set of technologies that combines sensors, information systems, enhanced machinery, and informed management to optimize production by accounting for variability and uncertainties within agricultural systems.
