Groundwater managers have a difficult time getting a sense of how much water farmers and urban water users extract from aquifers. Gravity Recovery and Climate Experiment (GRACE) is a satellite technology that uses microwaves to generate data that researchers use to build Earth gravity models. The models produced from GRACE data help water managers know how much water farmers and urban water planners have withdrawn from the ground. This helps communities manage their groundwater resources sustainably.
By 2050 two thirds of the world’s population will live in urban areas. This growth will cause an 80% increase in city water demand. To fulfill this growing need for water in cities, water will be taken away from rural and agricultural needs.
In the United States alone, beef production accounts for twenty percent of greenhouse gas emissions and it is the least efficient source of protein production. Americans will continue to eat beef; so designing a sustainable industry is essential to reducing emissions. In a new study, scientists explore two straightforward ways to achieve a sustainable industry – all without sacrificing your cheeseburgers.
Across the globe, rangelands are rapidly changing due to human-caused disturbances. New research shows that in Australia, livestock grazing is shifting the balance of plant diversity in favor of non-native species. This could pose serious conservation challenges for Australian rangelands in years to come.
Humans have long looked to the ocean for opportunities, sustenance, and growth. Today, advocates of “Blue Growth” aim to foster sustainable economic growth in the marine sector. Absent in the grandiose vision, however, is where our interaction with the ocean first began: fishing. Global fisheries production has stagnated: ecology is fragile, regulations are strict, and fish prices are low. So, what is the future for marine fisheries? What will be its role in Blue Growth?
Does news coverage affect the length of people’s showers? A recent scientific study seeks to understand how mass media is related to water use behavior, by examining the influence of abnormally high drought related news coverage in California’s San Francisco bay area. The researchers find a strong link between heightened news coverage and a reduction in urban water use, indicating that mass media has the potential to lead to significant behavioral changes.
Climate change is increasing storm severity globally. During storms, polluted sediment can be transported. A study focusing on the Meadowlands demonstrates how tide gates can prevent the transportation of contaminated sediment.
In the wake of large-scale hurricane-induced flooding, understanding the characteristics of waterbodies matters more now than ever. A new classification system called the Freshwater Continuum Classification can help effectively identify changes that can occur over time.
With rising consumer demand for organic foods, farmers need to explore new methods for pest control. A recent literature review identifies avenues for future research into natural predator-prey relationships that could yield novel alternatives to controversial technologies currently used.
