In southern Yemen, archaeologists have discovered evidence of ancient transitions from hunting and herding to irrigation agriculture around 5,200 years ago. The research team used GIS mapping and studied contemporary land and water rights to understand the development of expert knowledge of hydrology among early farmers.
The new satellite tool provides daily observations of small areas, allowing for improved yield assessments and modeling of water transfer. This enables the reorientation of irrigation towards crop parcels where it is most needed, facilitating significant improvements in cultivation practices.
Researchers warn that modern agriculture can lead to major disruptions of the world's water flows, particularly in the world's poorest regions. Ecosystem flips can have significant and sometimes devastating effects on human well-being, as global populations suddenly lose resources they are dependent on.
Global climate models project significant changes in water availability due to anthropogenic warming, with regions like high latitudes and Mediterranean basin expected to experience substantial decreases. Non-stationarity must be accounted for in water resources planning to ensure effective management.
Global water planning faces a fundamental shift due to changing climate patterns. Water managers must adapt to new, unpredictable conditions that challenge traditional approaches. The authors propose a revised framework incorporating shifting averages and variability.
A collaborative mapping tool developed by the Georgia Tech Research Institute (GTRI) allows emergency management officials to better coordinate event and incident planning. The system can track resources such as hospitals, transportation equipment, and water in real-time, enabling effective response and evacuation plans.
The Aquatest project aims to provide individuals and communities with the information they need to identify unsafe water and take action. The test, which can detect E. coli contamination, will be available in developing countries within 10 years, leading to improved water management and a potential decline in water-borne diseases.
A new risk assessment tool has been developed to help reduce the transfer of disease-causing bacteria from farmed environments to watercourses. The expert-weighted risk tool identifies fields and farmyards with the greatest likelihood of contaminating waterways, allowing farmers and landowners to prioritize clean-up efforts.
Seawater intrusion is a common cause of contamination in coastal aquifers worldwide, particularly in the Mediterranean region. In Spain, about 60% of coastal aquifers are contaminated, making it a serious phenomenon with significant economic and environmental impacts.
The CGIAR research program aims to develop climate-resilient crops like maize, sorghum, and millet that can withstand drought and heat. Researchers are using molecular biology tools to identify genetic hot spots in these crops, enabling them to capture solar energy more efficiently and produce greater yields.
The Comprehensive Assessment reveals that one-third of the world's population lives in areas where water is either over-used or cannot be accessed due to lack of infrastructure. The study calls for radical changes in water management to address the growing water crisis.
The USGS showcased its expertise in geospatial data sharing and the intersection of earth sciences with national security. The symposium brought together officials from various government agencies and state governments to discuss future coordination across the homeland security enterprise.
The study found that larger herd sizes grant better social status, land, and income, but also lead to deforestation and water scarcity. Poor families with small herds rely on charcoal sales, affecting animal health and child nutrition.
Researchers at MIT's Parsons Lab in Hawaii developed a technique to calculate the amount and distribution of groundwater flowing into coastal waters. The data will contribute to Kaeo Duarte's research on groundwater usage on Hawaii's dry western coast.
The report highlights the need for a multi-faceted approach to manage freshwater resources, including empowering local groups and increasing communication among disciplines. It also recommends protecting minimally impaired ecosystems and creating awareness of healthy ecosystems' importance to everyday living.
The GSA 2002 conference discusses the impacts of human activities on natural systems, including droughts, wildfires, and ground-water depletion. Researchers also explore the role of climate change in shaping Earth's history, as seen in sediment cores from the Great Blue Hole.
The new tool helps decision makers utilize long-range forecasts by explaining and evaluating their performance. It allows users to customize evaluations based on lead-times, seasons, and locations relevant to their specific needs.
A massive sand delta, over 325 feet thick and nearly 22 miles wide, was found in ancient shorelines of South Florida. This discovery suggests a river system significantly larger than present-day Florida once flowed through the state.
Riparian forest management prioritizes both water and forest health to protect essential links between land and water. The book provides site-specific guidelines for addressing fragmented ecosystems and diverse interest groups, ensuring the health of eastern riparian landscapes.
A new study by CSIRO, Southcorp Wines Pty Ltd, and the Viticulture CRC has found that grape yield and fruit quality can vary widely within small areas of vines. Precision viticulture offers a low-cost way to optimize both yield and quality, leading to improved financial outcomes and environmental sustainability.
The partners aim to enhance the EPA's BASINS program by adding uncertainty and probability assessment capabilities. This will enable decision-makers to prioritize management actions that yield the best results. The collaboration also seeks to improve stakeholder involvement and promote proactive watershed management.
A new study by Penn State researchers improves the regional climate assessment of the Mid-Atlantic Region. The research involved gathering input from over 95 stakeholders representing industry, environmental groups, government, and research organizations. Key findings highlight the importance of human health in addressing global change...
The study found that public perceptions of the forest prioritize residential quality of life, community, and environmental ethics. This differs from land managers' focus on tangible aspects like water, wood, and wildlife.
The USGS is providing crucial information for restoring the South Florida ecosystem through multidisciplinary research activities. The latest data on pre-development environmental conditions, contaminant transport, and physical conditions in Florida Bay are being shared to inform land and water resource managers.
The current floods in North Dakota have broken multiple records, including a 100-year-old record of 85,000 cubic feet per second. The Red River's predicted crest is expected to reach 54 feet, posing significant threats to emergency managers and evacuation orders.
A workshop on long-term stewardship of the US nuclear weapons complex explored the need for institutions, information, and strategies to protect people and the environment. Key findings include the potential for decades-long cleanup efforts and the importance of reliable institutional controls and waste disposal facilities.
