  • Drought: A cause of riots
    on September 26, 2017 at 1:05 pm

    The scientific community has been working on the possibility of a relationship between periods of drought and rioting for several years. Now a team has formally verified this hypothesis by studying almost 1,800 riots that occurred over a 20-year period in sub-Saharan Africa. The researchers observed a systematic link between the sudden depletion of water resources and the outbreak of unrest. They also succeeded in quantifying the impact of geographic and social factors on the same link. […]

  • Climate insurance is rarely well thought out in agriculture
    on September 25, 2017 at 3:33 pm

    Internationally subsidised agricultural insurance is intended to protect farmers in developing countries from the effects of climate change. However, it can also lead to undesirable ecological and social side effects, as researchers have now explained. Their article also contains recommendations for improved insurance schemes which in future should also take account of ecological and social aspects in addition to economic issues. […]

  • Scientists monitor Silicon Valley's underground water reserves -- from space
    on September 25, 2017 at 2:57 pm

    Scientists monitoring Silicon Valley's underground water reserves from space have found that water levels rebounded quickly after a severe drought that lasted from 2012-15. The research points to the success of aggressive conservation measures. It also helps to lay the groundwork for low-cost monitoring of subterranean water reserves in California and elsewhere in the world. […]

  • A cereal crop survives heat and drought
    on September 18, 2017 at 6:30 pm

    Scientists have published the genome sequence of Pearl millet, a drought resistant crop plant most important in arid regions in Africa and Asia. This plant is important to small and medium farmers who grow the plant without larger irrigation. Pearl millet delivers a good harvest index under drought and heat conditions when rice, maize or wheat already have no grains anymore. […]

  • Water conservation can have unintended consequences
    on September 14, 2017 at 7:24 pm

    Conventional wisdom dictates water conservation can only benefit communities affected by drought. But researchers have deduced that indoor residential conservation can have unintended consequences in places where systems of wastewater reuse have already been implemented, diminishing both the quantity and quality of influent available for treatment. […]

  • Estimating crop yield from satellite data
    on August 16, 2017 at 5:47 pm

    Without advanced sensing technology, humans see only a small portion of the entire electromagnetic spectrum. Satellites see the full range -- from high-energy gamma rays, to visible, infrared, and low-energy microwaves. The images and data they collect can be used to solve complex problems. For example, satellite data is being harnessed for a more complete picture of cropland and to estimate crop yield in the US Corn Belt. […]

  • Incomplete drought recovery may be the new normal
    on August 9, 2017 at 6:02 pm

    The amount of time it takes for an ecosystem to recover from a drought is an important measure of a drought's severity. During the 20th century, the total area of land affected by drought increased, and longer recovery times became more common, according to new research published by Nature by a group of scientists including Carnegie's Anna Michalak and Yuanyuan Fang. […]

  • Drought-affected trees die from hydraulic failure and carbon starvation
    on August 7, 2017 at 3:15 pm

    Drought-caused tree deaths are produced by a combination of hydraulic failure and carbon starvation, shows new research. The finding, based on a meta-analysis by 62 scientists from across the world, will improve predictive models of how trees die in response to heat, drought, and other climate stresses. […]

  • Climate scientists create Caribbean drought atlas
    on August 1, 2017 at 8:03 pm

    Atmospheric scientists have developed the first-of-its-kind, high-resolution Caribbean drought atlas, with data going back to 1950. Concurrently, the researchers confirmed the region’s 2013-16 drought was the most severe in 66 years due to consistently higher temperatures – a hint that climate change is to blame. […]

  • Successful prediction of multi-year US droughts and wildfire risk
    on August 1, 2017 at 1:45 pm

    A new study shows that difference in water temperature between the Pacific and the Atlantic oceans together with global warming impact the risk of drought and wildfire in southwestern North America. A new model proves capable of much longer-term forecasts of mega-drought and active wildfire seasons than those currently available to people in agriculture, water management and forestry. […]

    on July 31, 2017 at 1:53 pm

    Aardvarks prove to be highly susceptible to the warmer and drier climates that are predicted for the western parts of southern Africa in the future. During the study of a number of aardvarks, all but one of the study animals -- as well as other aardvarks in the area -- died because of a severe drought, with air temperatures much higher than normal and very dry soil in the area. […]
