Why a 4-Degrees World Won't Cause Just One Water Crisis

There is much talk of a water crisis. We who work in water don't really see just one; we see lots of different water crises already now, getting worse as we move towards 2 and eventually 4 degrees above pre-industrial temperatures. Floods in some places, droughts in others, poor operation and maintenance making infrastructure unable to protect citizens in some places, lack of enforcement of rules leading to pollution crises or rampant overuse of groundwater in many others. So there are lots of water crises, some caused by nature, some by humans and most some a combination of the two.

Generating Marine Electricity: Transitioning From Subsidies to Commercial Financing

Alexander McPhail's picture
In-stream tidal units convert the energy of tides and currents into power – a type of hydropower which has operated successfully for decades. No matter what you call it -- wave, in-stream tidal, river current, or hydro turbines; or where it sits -- sitting on the river bottom or suspended from a barge -- the technology has proven itself. What has remained more elusive is the much-needed transition from subsidies to commercial financing.

International Day for Biological Diversity: Biodiversity Can Provide the Basis for Effective Water Management

This year International Day for Biodiversity (May 22) is focused on “Water and Biodiversity” to coincide with the United Nations declaration of 2013 as the International Year for Water Cooperation. Effective water management has traditionally been viewed as an important factor in maintaining biodiversity in ecosystems. The opposite is increasingly viewed as critical: biodiversity can provide the basis for effective water management.

Stepping Up Efforts to Address Water Issues

As recognized by the World Economic Forum at Davos earlier this year, water insecurity is one of the greatest risks facing the world today.  Increased water demand from growing populations and economies, combined with more uncertainty in supply due to expected climate change impacts, require a radical change in the priority we give to managing our water resources and systems to supply water to people.  Over the next two decades, water will be needed to feed a planet of 9 billion people and generate energy to meet increased demand.

Cutting Water Consumption in Concentrated Solar Power Plants

Concentrated solar power (CSP) systems are a great promise for renewable energy at scale.  But they can use a lot of water, which is a problem since they tend to be located in places where water is scarce. Some concentrated solar technologies need to withdraw as much as 3,500 liters per Megawatt hour (MWh) generated.

As mentioned in the previous post, the three grand prize winning teams of the Sanitation Hackathon boarded from their home countries – Indonesia, Senegal, Tanzania, and the UK – for a week-long trip to Silicon Valley, hosted by IDEO.org. They met with companies such as Zynga, the world’s leading social gaming company, Facebook, the social network giant, AirBnB, a travel site, The Hub, a collaborative work space, and Indiegogo, a crowdfunding platform. The young web developers learned about the importance of data, how to reach large networks, why trust and collaboration are key, and what makes a crowdfunding campaign successful.

Toilets: There’s an App for That

It’s no secret that the rapid rise in access to mobile phones has created a new vehicle for the delivery of information and services, particularly for people at the base of the pyramid – or those who live on less than $1.25 a day. The challenge we, as development practitioners, face is understanding how to leverage mobile phones in ways that empower citizens as agents of change who can influence and drive development processes in their communities.
