Satellite data reveal variability in intensity of groundwater use for different crops, a boon for irrigation policymaking across the state — ScienceDaily

Researchers at the University of California San Diego report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the understanding of sustainable groundwater in California’s San Joaquin Valley.

Their work could be revolutionary for managing groundwater use in agricultural regions around the world, as groundwater monitoring and management have been notoriously difficult to carry out due to lack of reliable data.

The satellite-based InSAR (interferometric synthetic aperture radar) is used to make high-resolution maps of land surface motion in space and time, including measurement of subsidence (or sinking). Subsidence can occur when large amounts of groundwater are removed from underground stores, called aquifers.

The study, published in the journal Environmental Research Letters, took advantage of the incredibly fine-scale resolution of InSAR to evaluate subsidence patterns according to crop

  • Zynga announced Monday that FarmVille is shutting down on Facebook by the end of the year.
  • The news comes after Facebook announced it would stop supporting games that run on Adobe’s Flash Player by December 31.
  • The farm simulation game launched in 2009 and quickly rose in popularity, drawing millions of online players.

New technology to fight plagues and pathogens in crops

Researchers at the Institute of Plant Molecular and Cellular Biology (IBMCP), mixed center of the Polytechnic University of Valencia and the Spanish National Research Council (CSIC), have developed a new technology that will help fight, in a natural way that is respectful towards the environment, against the plagues and pathogens that affect crops.


The team of the IBMCP, coordinated by José Antonio Darós, scientific researcher at the CSIC, has patented a new method that makes it possible to produce, in a fast and affordable way, large amounts of dsRNA. This substance is a natural molecule that can act in an extraordinarily selective and efficient way against pathogens and plagues, silencing their genes and thus preventing them from affecting crops.

“If a nematode, insect or any other arthropod ingests these dsRNA molecules, they can end up dying or, in the best case, have their growth altered. By silencing
