Soil Nitrogen Age Measurement Could Help Precision Agriculture Scientists Find

Scientists have developed a model to calculate the age of nitrogen in corn and soybean fields, which could lead to improved fertilizer application techniques to promote crop growth while reducing leaching. Nitrogen, a key nutrient for plants, can cause problems when it leaches into water supplies.


Solar Cells Help Purify Water In Rural Locations In Developing Countries

Researchers at Lund University in Sweden have developed small, portable solar cell water purification plants. With the help of Nobel Peace Prize recipient Muhammad Yunus the purification plant stations, called Micro Production Centres (MPC), have now been placed across rural Bangladesh.

Urbanization Provides Opportunities for Transition to a Green Economy, Says New Report

“Integrating the Environment in Urban Planning and Management: Key Principles and Approaches for Cities in the 21st Century,” a report launched on 8 April 2014 jointly by the United Nations Environment Programme (UNEP) and Cities Alliance at the 2014 World Urban Forum in Medellin, Colombia, says that as consumers of over 75% of natural resources, cities can be major contributors to efficiency and sustainability.


The Effects of Population on the Depletion of Fresh Water

This article compares quantitative estimates for groundwater loss and glacier recession and considers the significance of their relative magnitudes. It concludes that the effect of food and agriculture, hence of population, may be significantly greater than that attributable to the global warming caused by industrial production and transport.


Realizing Water, Sanitation and Hygiene for All

This article focuses on the background of the problem, what it means for nearly half the people of the developing world who lack adequate sanitation and hygiene. Today, an estimated 2.4 to 2.6 billion individuals lack access to any type of improved sanitation facility according to the World Health Organization (WHO).  According to the Centers for Disease Control and Prevention (CDC) half of the developing world, more than 35 % of the world’s population lack access to adequate sanitation. And, poor sanitation and hygiene are inextricably linked to water quality.

 

 

 

 


Sylvia Earle Alliance’s Mission Blue and Partners Establish Ocean Hope Spots

On October 22, 2013, news coming from the 3rd International Marine Protected Areas Congress (IMPAC 3) reported that Dr. Sylvia Earle, Mission Blue and the International Union for Conservation of Nature (IUCN),  have launched 31 new Mission Blue Hope Spots -- places of special significance in the ocean where Mission Blue will focus its efforts. There are now 50 Hope Spots globally. Mission Blue calls this “a path forward for protecting our Blue Heart.”


FDA Withdraws Arsenic-Based Animal Drug Approvals

At the request of two drug companies, the Food and Drug Administration (FDA) has announced that it will withdraw approvals for three of four arsenic-based drugs currently approved for use in food animal production. A fourth arsenic-based drug used to make turkeys and chickens grow faster, among other purposes, will remain on the market.


Project to Counteract Deteriorating Water Quality in Ecosystems Launched at Budapest Water Summit
