The theme of this year’s #worldwaterday focuses on water and energy. And for good reasons.
For the last six years, a power plant in San Luis Potosi, Mexico has bought water from a nearby wastewater treatment plant to use in its cooling towers (instead of using freshwater). This operation, Project Tenorio, a public-private partnership, continues today and has already resulted in the reduction of groundwater extraction of at least 48 million cubic meters (equivalent to 19,000 Olympic size pools) and increased aquifer sustainability.
This is a good example of the water and energy nexus in practice: the wastewater treatment plant covers almost all of its operating costs from this additional revenue stream and the power plant gets a more reliable water source that is also 33% cheaper than groundwater in that area.
Treated wastewater has been used to reduce the water requirements of power plants in several other countries as well, as water supply becomes more variable or disappears. In the US, for example, around 50 power plants are using treated wastewater for cooling in order to adapt to water shortages. However, innovative integrated approaches like these are still more of an exception than the norm.
While recently touring drought-stricken California, President Obama remarked: "We can't think of this simply as a zero-sum game. It can't just be a matter of there's going to be less and less water so I'm going to grab more and more..."
In his State of the State address, California’s Governor, Jerry Brown, declared a drought emergency. He suggested: “Among all our uncertainties, weather is one of the most basic. We can’t control it. We can only live with it…We can take this drought as a stark warning of things to come.”
He further emphasized the need to conserve water, expand storage, rethink water rules, invest in drinking water protection, and rethink the amount of state water each sector receives.
But, how can California move away from existing rules, expectations, and legacies that include multi-layered federal subsidies and senior water rights to a non-zero sum approach to resolve competing and conflicting water realties?
The three points made in my previous post—that services particularly fail poor people, money is not the solution, and “the solution” is not the solution—can be explained by failures of accountability in the service delivery chain. This was the cornerstone of the 2004 World Development Report, Making Services Work for Poor People. In a private market—when I buy a sandwich, for example—there is a direct or “short route” of accountability between the client (me) and the sandwich provider. I pay him directly; I know whether I got a sandwich or not; and If I don’t like the sandwich, I can go elsewhere—and the provider knows that.
India’s stellar economic performance during the past decade has brought immense benefits to the people. Emmployment opportunities have increased, enabling millions to emerge from poverty.
But rapid growth has been clouded by a degrading environment and a growing scarcity of natural resources. Today, India ranks 155th among 178 countries accounting for all measurable environmental indicators, and almost dead last in terms of air pollution. What’s more, more than half of the most polluted cities in the G-20 countries are in India. The deteriorating environment is taking its toll on the people’s health and productivity – and costing the economy a staggering Rs. 3.75 trillion each year (US$80 billion) - or 5.7 percent of GDP. So, does growth – so essential for development – have to come at the price of worsened air quality and other environmental degradation? Fortunately, India does not have to choose between growth and the environment.
Bishkek, Kyrgyz Republic – Laura Tuck, the vice president for the World Bank’s Europe and Central Asia unit, talks about her trip to Kazakhstan, the Kyrgyz Republic, Tajikistan and Uzbekistan and important issues related to the economic growth of the region that she discussed in these Central Asian countries.
Vietnam is one of the world's development success stories. It is undeniable.
Between 1990 and 2010, Vietnam grew at an average annual rate of 7.4 percent—one of the world’s top five growth performance records, anywhere, over the same 20-year period. In the process, the incidence of poverty has declined dramatically, from 58 percent in 1993 to about 10 percent today. Nowadays Vietnam is no longer considered a low-income country: it has attained lower-middle income status.
Yet this successful economic transition has also generated a number of challenges. Chief among them is that of sustaining economic growth going forward.

Right now, as you read this, wherever you are, we are in uncharted territory. Our global population of 7.1 billion is headed for more than 9 billion by 2050. With our growing numbers and aspirations for shared prosperity comes a growing demand for energy to power homes, businesses, industry and transport. Our continuing reliance on fossil fuels is generating pollution and a dangerously high amount of greenhouse gas emissions – this past summer, the concentration of CO2 in the atmosphere passed levels not seen in 3 million years.
If you were in Beijing last week, you felt the impact in your lungs: Just 16 days into the new year, the city woke up to its first “airpocalypse” of 2014, the latest in a series of dangerously high smog days. Beijing’s mayor announced plans the same day to cut coal use by 2.6 million tons and ban heavily polluting vehicles.
That was an important local step, and we are seeing forward-thinking cities and national governments make similar moves as they develop the architecture for a cleaner, low-carbon future.
