            "description": "According to a July 29 2022 report from the International Food Security and Nutrition Working Group, the worst drought conditions in 70 years across the Horn of Africa have more than 16 million people coping with a shortage of drinking water. Yields of key crops are down for the third year in a row, milk production is in decline, and more than 9 million livestock animals have been lost due to a lack of water and suitable forage land. At the same time, regional conflicts, COVID-19, locusts, and the Ukraine War have caused price spikes and shortages of basic commodities. An estimated 18 to 21 million people now \"face high levels of acute food insecurity\" in Ethiopia, Kenya, and Somalia.These animations depict root zone and surface soil moisture observations and forecasts from the NASA Hydrological Forecast and Analysis System (NHyFAS). Reds depict areas with soil moisture percentages below the average, while blues reflect areas that are above average (often due to passing storms). The first 27 seconds of the animation show soil moisture from August 2020 through June 2022. The final 10 seconds show forecasts for July through December 2022, including the next rainy season. Root zone moisture is critical for long term crop growth. New seedlings are mostly dependent on surface water, but then as plants grow and sink deeper roots, they are sustained by moisture in the top layer of the soil. || ",

It includes a quick start guide for educators and first-hand stories (blogs) for learners of all ages by NASA visualizers, scientists and educators. We hope that your understanding and use of NASA's visualizations will only increase as your appreciation grows for the beauty of the science they portray, and the communicative power they hold. Read all the blogs and find educational resources for all ages at: the Earth Science Week 2015 page.I'm a hydrologist, which means I study how water moves around on land. Well, “on land” isn’t exactly right. It turns out that most of the interesting processes happen beneath the land surface, hidden from view. You might think, for example, that rivers fill from above — it rains and the water that doesn't sink into the ground runs off into the rivers. But in fact, about 80 percent of the water in rivers comes from underground. Rain soaks into the ground, adding water to the water table. When the water table rises to where it intersects with the land surface (on the side of a hill or even gently sloping \"flat\" land), the water penetrates through to the surface and runs downhill. Eventually, the flowing water carves out a ditch and you have a stream and ultimately a river.Let me show you what I mean: || ",

The title of this event was \"Vital Signs: Taking the Pulse of Our Planet\", and the speakers at this event included several Earth Scientists from Goddard Space Flight Center.  This animation was used in the beginning of the event to illustrate the interconnectedness of the many Earth-based data sets that NASA has produced over the last decade or so.  The animation simulates a view of the Earth from the International Space Station, over which interconnected data sets are displayed as if on a head-up display. || ",

            "title": "Earth's Water Cycle",
            "description": "Water is the fundamental ingredient for life on Earth. Looking at our Earth from space, with its vast and deep ocean, it appears as though there is an abundance of water for our use. However, only a small portion of Earth's water is accessible for our needs. How much fresh water exists and where it is stored affects us all. This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites as well as cartoons to describe Earth's water cycle and the continuous movement of water on, above and below the surface of the Earth. Sensors on a suite of NASA satellites observe and measure water on land, in the ocean and in the atmosphere. These measurements are important to understanding the availability and distribution of Earth's water — vital to life and vulnerable to the impacts of climate change on a growing world population.NASA Earth Observing System Data and Information Systems (EOSDIS) EOSDIS is a distributed system of twelve data centers and science investigator processing systems. EOSDIS processes, archives, and distributes data from Earth observing satellites, field campaigns, airborne sensors, and related Earth science programs. These data enable the study of Earth from space to advance scientific understanding.For questions, please contact eosdis-outreach@lists.nasa.gov || ",

            "description": "Instruments on the Landsat satellites capture images in the visible spectrum, but they also take images in wavelengths invisible to the naked eye. Landsat's thermal imager captures land surface temperature data. As farmers irrigate fields, water evaporates from the soil and transpires from plants' leaves. The combined process is called evapotranspiration. Evapotranspiring water absorbs energy, so farm fields consuming more water appear cooler in the thermal band. Landsat-based evapotranspiration measurements provide an objective way for water managers to assess on a field-by-field basis how much water agricultural growers are using. The measurements have even been used to help settle water rights conflicts in court. || ",

            "description": "Experts now estimate that Tamarisk (saltcedar) has infested more than 3.3 million acres in the western United States. Tamarisk is one of our most harmful invasive species because the plant's long roots tap into underground aquifers. Its groundwater-absorbing qualities may be adding to the severity of the drought in the western U.S.NASA and the USGS are working together to develop a National Invasive Species Forecasting System (ISFS) for the management and control of invasive species. The ISFS combines NASA Earth observations and models with field data to enhance USGS capabilities to map, monitor and predict the spread of significant invasive plant species.Tamarisk's extensive root system can reach up to 50 feet laterally and 100 feet in depth to access the water supply. As this invasive plant draws up large amounts of water, it can lower the water table. Native plants with shallower root systems have to compete for an already-dwindling water supply. One large Tamarisk plant can absorb up to 200 gallons of water per day - that's twice the amount the average person uses in the same timeframe. || ",
