1 June 2015, The Diplomat, The world water crisis is both severe and entirely avoidable: With the approach of World Environment Day, on June 5, it is worthwhile to reflect on a major crisis that is now confronting the world but receiving inadequate attention. If current trends continue, the world will face a water crisis that will be unprecedented in human history. During the past decade, there has been extensive discussion on the adequacy of physical availability of water to meet escalating needs for various uses for an expanding global population and accelerating economic activities. However, inadequate attention has been paid to the rapid deterioration of water quality, which is further reducing a significant stock of water that can no longer be used without expensive and sophisticated treatment. Water, unlike oil or minerals, is a renewable resource. This means it can be used, treated properly, and then reused. This cycle with good management can continue indefinitely. It has been estimated that each drop of the Colorado River water is used seven times. With good management, there is no reason why this could not be increased to 20 or 30 times. The current overwhelming concern is that the world is going to run out of physical availability of water in the foreseeable future. We differ. Read More here

1 June 2015, Climate News Network, Overheating Earth staggers into Last Chance Saloon: Hard bargaining in Bonn this week will probably decide whether the crucial climate talks in Paris in December can save human civilisation from ultimate collapse. The text of the agreement on how the world will tackle climate change and set targets that will keep global temperatures from rising more than 2°C above pre-industrial levels is being negotiated in Bonn this week. The 2°C limit has been set by politicians to prevent the planet overheating dangerously − but the cuts in carbon emissions required to achieve it have so far not been agreed.
It is this gap between the policy goals agreed by world leaders and their lack of action to achieve them that the Bonn conference seeks to address. The meeting, which opened today, will last for 10 days as working groups grapple with action to reduce carbon emissions, how to finance technology transfer, and how to adapt to sea level rise and other unavoidable consequences of present warming − such as the current heatwave affecting India, where temperatures in some southern states have topped 47°C.

24 May 2015, Los Angeles Times: Turning sewage into drinking water gains appeal as drought lingers. ‘s a technology with the potential to ease California’s colossal thirst and insulate millions from the parched whims of Mother Nature, experts say. But there’s just one problem — the “yuck factor.” As a fourth year of drought continues to drain aquifers and reservoirs, California water managers and environmentalists are urging adoption of a polarizing water recycling policy known as direct potable reuse. Unlike nonpotable reuse — in which treated sewage is used to irrigate crops, parks or golf courses — direct potable reuse takes treated sewage effluent and purifies it so it can be used as drinking water. It’s a concept that might cause some consumers to wince, but it has been used for decades in Windhoek, Namibia — where evaporation rates exceed annual rainfall — and more recently in drought-stricken Texas cities, including Big Spring and Wichita Falls.

14 May 2015, Truthdig: Migration Is an Act of Desperation, Not a Crime.….The Norwegian Refugee Council and Internal Displacement Monitoring Centre released a report in early May revealing that there were 38 million internally displaced people last year alone, nearly 5 million more than the year before. The record-breaking number includes 11 million refugees who were newly displaced and clustered in the Middle East and Africa, including Syria, South Sudan, Nigeria and the Democratic Republic of Congo. Council Secretary-General Jan Egeland said, “These are the worst figures for forced displacement in a generation, signaling our complete failure to protect innocent civilians.” Read More here
