Those making land use decisions to reduce the harmful effects of climate change have focused almost exclusively on greenhouse gases — analyzing, for example, how much carbon dioxide is released when a forest is cleared to grow crops. A new study in Nature Climate Change aims to present a more complete picture — to incorporate other characteristics of ecosystems that also influence climate. "We know that forests store a lot of carbon and clearing a forest releases carbon dioxide...

Researchers recommend best practices for commercial production in water-limited regions Loaded with antioxidants and phytochemicals, the artichoke is becoming more popular as consumer interest in specialty products swells. And while 90% of the artichokes grown in the United States come from California, growers in Texas are working to introduce globe artichokes as commercial specialty crop in their region. They say the healthy vegetable has the potential to provide new economic...

New strategies provide important irrigation information, promote water savings Although water consumption and conservation are widely recognized as significant environmental concerns in the United States, most Americans are still unaware of the major impact of landscape irrigation on their regional water supplies. One startling example: a 2004 study of homeowners in College Station, Texas, estimated that more than 24 to 34 million gallons of excess water were used annually for landscape...

Once lost in the mists of time, the colonial hydrology of the northeastern United States has been reconstructed by a team of geoscientists, biological scientists and social scientists, including University of New Hampshire Ph.D. candidate Christopher Pastore. The results, which extend as far back as the year 1600, appear in the current issue of the journal Environmental Science & Technology in the article "Tapping Environmental History to Recreate America's Colonial Hydrology." The...

The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa and South America, have been drying up in the past decade, a group of researchers conclude in the first major study to ever examine "evapotranspiration" on a global basis. Most climate models have suggested that evapotranspiration, which is the movement of water from the land to the atmosphere, would increase with global warming. The new research, published online this week in the journal...

Study addresses impact of deficit irrigation on quality and yield Texas AgriLife Research scientists have recently completed a two-year study on the impact of deficit irrigation and plant density on the growth, yield and quality of short-day onions. Deficit irrigation is a strategy in which water is applied to a crop during its drought-senstitive stages of development and is either applied sparingly or not at all during other growth stages, particularly if there is sufficient rainfall,...

Earth has a limited amount of water that recycles itself in what is called the "Ëœwater cycle'. Climate change, weather and human life are highly affected by changes in this continuous, interconnected cycle. Observing and monitoring the key variables governing the global water cycle is essential to our understanding of the Earth's climate, forecasting our weather, predicting floods and droughts, and improving water management for human use. Recent advances in Earth observation (EO)...

Farming may soon be revolutionized through an unlikely method, the laser. Jan Kleissl of the University of California believes laser technology can be used as a way to conserve millions of gallons of water when farmers water their crops. Kleissl and his team of students are using a scintillometer to measure the amount of water crops lose to evaporation, and are finding the peak times in which water disappears. The researchers hope to help farmers see how efficiently their water is being...

ETTER "“ At the end of the day, drought tolerance in corn has to equate to good yields and good quality, not just good looks, said a Texas AgriLife Research scientist.Dr. Wenwei Xu, AgriLife Research corn breeder from Lubbock, is working with crosses between temperate and tropically adapted varieties of corn to find a drought-tolerant plant that performs well under reduced irrigation."With the continuing decline of the Ogallala Aquifer water level and increasing cost of pumping water,...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
