• Major food companies must adapt to growing global water risks

    Escalating water competition, combined with weak government regulations, increasing water pollution, and worsening climate change impacts, is creating unprecedented water security risks for the food industry. In California, an estimated half-million acres of farmland have already been fallowed by a prolonged drought, causing more than $1 billion of economic losses for the agriculture sector. Major U.S. food companies need to adopt far stronger practices to use limited global water resources more efficiently, according to a new report. The report ranks the U.S. thirty-seven largest food companies on how effectively they are managing precious freshwater supplies. While a relatively small number of firms are taking broad actions to manage water risks in their operations and supply chains — Unilever, Coca-Cola, Nestlé, PepsiCo, General Mills, and Kellogg, among those — most have a long way to go in using water more sustainably, the report concludes.

  • Seismic safety of nuclear power plants in Scandinavia to improve

    Since the Fukushima accident, Nordic nuclear power plant areas have given greater priority to understanding the safety implications of seismic events. The Technical Research Center of Finland (VTT) and various Nordic players are co-developing new methods of making seismic hazard estimates of anticipated earthquakes in Fennoscandia — the region comprising the Scandinavian Peninsula, Finland, Karelia, and the Kola Peninsula in Russia.

  • Sea level rise accelerated over the past two decades, research finds

    Sea level rise sped up over the last two decades rather than slowing down as previously thought, according to new research. The research corrects other studies which relied on records from tide gauges and satellites, records which have shown sea level rise to be slowing slightly over the past twenty years. This slowing down surprised scientists: As the ice sheets of West Antarctica and Greenland melt and send huge amounts of water into the ocean, climate models predicted that sea level rise would accelerate, not slow down. The new research, in which researchers used data sets generated by both tidal gauges and altimetric satellites, found, however, that the record of sea level rise during the early 1990s was too high. When adjustments are made for the initial error, the rate of sea level rise is not slowing down but accelerating, and the IPCC climate modelling proves right.

  • Florida coastal communities’ infrastructure officials say state government ignores sea level rise

    Water officials serving communities along Florida’s 1,200-mile coastline say the state government has rejected the scientific consensus on man-made climate change. These officials are worried that unprecedented flood levels will erode their buildings, push seawater into drinking water wells, and overburden aging flood-control systems. Despite warnings from water and climate experts about risks to Florida’s cities and drinking water, deniers and skeptics of climate change science have suppressed efforts at all levels of state government to address these risks.

  • DHS selects U Rhode Island to partner on coastal resiliency research

    The University of Rhode Island has been selected by the U.S. Department of Homeland Security to be one of two primary partners, along with Jackson State University, in the Coastal Resilience Center of Excellence at the University of North Carolina at Chapel Hill. The selection, which could result in funding in excess of $2.5 million, enables URI to provide key research designed to help build resiliency along the U.S. coastlines and prepare for increasingly severe coastal hazards.

  • São Paulo water crisis shows the failure of public-private partnerships

    São Paulo’s ongoing water crisis has left many of the city’s twenty million or more residents without tap water for days on end. Brazil’s largest metropolis is into its third month of water rationing, and some citizens have even taken to drilling through their basements to reach groundwater. Most commentators agree that the crisis is to blame on multiple factors, but few have questioned the role of the water company in charge: Sabesp. Just like the “natural monopolies” enjoyed by water companies in the United Kingdom, Sabesp has a publicly guaranteed monopoly, yet its profits are part-privatized — earlier this year it paid out R$252 million (US$83 million) in dividends. As is the case with other private companies, when deciding whether to make the necessary investments to prepare for possible water shortages, Sabesp has had to choose whether to safeguard the public supply or increase the value of its shares. As a result, the most essential resource of all has now become a struggle in São Paulo. Responsibility for this crisis lies with Sabesp and two decades of running water supply as a for-profit service. It is a failure of public-private partnership. As climate change and other environmental factors make water crises more likely, we better rethink the way water is managed worldwide.

  • States, cities vying to become U.S. “cyber hub”

    The global cybersecurity market reached $67 billion in 2011, and it is projected to grow as high as $156 billion by 2019. The need for cybersecurity solutions and experts is going to grow as more companies such as Sony Pictures, Target, Home Depot, and Chase are hacked, consumers demand better online security, and businesses become more aware of the potential cost to their sales and reputation if they do not provide cybersecurity. As private sector firms compete with government agencies for the best cyber professionals, cities and states are also competing to be the country’s “cyber hub.”

  • Nepal should use updated, upgraded building codes in post-disaster construction: Experts

    Urban planners and disaster experts who have been arriving in Kathmandu to inventory, assess, and make recommendations have been urging the Nepalese authorities to “Build it back better.” There are plenty of examples of post-disaster construction built significantly safer, using low-cost traditional materials and methods. Nepal has last updated its building code in 1994.

  • North Carolina to accept findings of new sea-level rise scientific report

    Reversing a previous State General Assembly law prohibiting state agencies and communities from using the findings of a 2012 climate change report as a basis for zoning and infrastructure planning regulations, the government of North Carolina has now moderated its opposition to further scientific findings concerning climate change. Under public pressure, legislators relented, agreeing to allow the Science Panel of the North Carolina Coastal Resources Commissioner (CRC), subject to some limitations, to write a new report on sea level rise along the state’s coast.

  • MIT Energy Initiative releases report on the future of solar energy

    Solar energy holds the best potential for meeting humanity’s future long-term energy needs while cutting greenhouse gas emissions — but to realize this potential will require increased emphasis on developing lower-cost technologies and more effective deployment policy, says a comprehensive new study released earlier this week by the MIT Energy Initiative (MITEI). The report highlights the enormous potential of this energy and discusses pathways toward affordable solar energy.

  • Geologist: Cities located next to earthquake “time bombs” should prepare for the inevitable

    A geologist, who is the author of the forthcoming Earthquake Time Bombs, points to several areas around the worlds where large cities lie on or adjacent to a major plate boundary creating a ticking time bomb: Tehran, the capital of Iran; Kabul in Afghanistan; Jerusalem in the Middle East; Caracas in Venezuela; Guantanamo, Cuba; Los Angeles, California; and the Cascadia Subduction Zone off the northwestern United States and near British Columbia. “These places should take lessons from the regions that already have experienced major earthquakes, including Nepal,” he says.

  • Water agencies in Sacramento, Calif. area want state water restrictions rewritten to reflect climate

    Last month, Governor Jerry Brown ordered California’s water agencies to reduce potable urban water use by 25 percent on average over 2013 levels by 28 February 2016. Leaders of Sacramento-area water agencies are now calling for a rewrite of the proposed framework to reflect climate. They argue that the framework is unfair because inland communities require far more water to achieve the same water functions as coastal communities. They also say the region is being punished for its dry heat, while coastal communities are rewarded for their moderate climate.

  • App checks water for contamination

    Researchers have created a mobile app which can determine just how contaminated a sample of water might be. Using tiny pills containing contaminant-detecting enzymes, users can first determine whether their water is clean or not. If the water is clean, the pills will change the color of the water. If it is contaminated with pesticide, heavy metals, or bacteria such as E. coli, it will remain clear. The app complements the pills by analyzing a series of photos of the water to determine just how contaminated the water is.

  • Corruption, lax building codes exacerbate natural disasters in poor countries

    While all heavily populated earthquake zones face the challenge of preparing for inevitable but unpredictable quakes, the poorest zones face the most risk as they invest less in building resilience and safe construction practices.Nepali experts note that bribery, lax law enforcement, and a lack of land-use controls left buildings vulnerable to seismic disasters.

  • Using shotcrete to make tunnels withstand terrorist attacks

    Conflagrations and terrorist attacks are a threat for tunnels and bridges, so engineers are searching for ways to make tunnels and bridges as robust as possible. Construction materials, such as special types of high-performance concrete, which can partly absorb the impact of explosions, already exist, but due to their manufacturing principle, they cannot be made in any other shape than the slab, which cannot be used for cladding surfaces with complex geometries. A new type of shotcrete — which used to be considered impossible to manufacture — was created by scientists to render the structures more robust. Despite its high steel and synthetic-fiber contents, it can be sprayed on easily.
