A large part of rural India is dependent on hand-operated water pumps, simply called “hand pumps” for their water needs. The hand pumps are low maintenance and work well, but only until the water depth is about 30 meters. Beyond that you would need an electric/diesel pump. But in a remote area, both electricity and diesel would be difficult to find.
The problem is aggravated during summers when the water table recedes. A lot of time and effort is wasted to fetch water manually, and it is the women folk who have to suffer the most.

Sometime back we had reported on the rise of solar pumps in India. Now some of the planned projects have started taking shape and are showing progress. Information available from the Indian Ministry of New and Renewable Energy shows that 50,000 solar pumps have been sanctioned for installation in various states for both irrigation and drinking water applications.
This includes 20,000 solar pumps which will come up in remote rural areas to provide piped drinking water to the residents of as many hamlets across the country. Non availability of electricity in these places otherwise makes it difficult to supply piped water to the households.
The program is essentially a scale up of pilot exercises carried out in a number of districts over a number of year. To begin with a high yield (at least 2000 litres/hour capacity), potable water borewell is selected. It is then fitted with a small solar water pumping system and an elevated tank. The storage tank provides piped water to the doorstep of the households. Best of all, the system does not require any battery and potentially has a long life. In most cases, the borewell already has a hand water pump, which continues to function even after installation of the solar pump.
Some systems also integrate rain water harvesting, while availability of already existing structures helps to reduce the system cost (rooftop solar installation). Even though the system is installed using grant money, it is recommended that the local panchayat (which is the village level elected governing body) collect some small payments for water usage. This helps to keep a check on water wastage as well as build a corpus for future O&M.
The capital cost of the total system for a small village of about 250 inhabitants is about $8000, excluding the cost of water treatment and drilling the borewell. The states have been asked by the central ministry to prepare a list of the beneficiary hamlets.

An Indian company has announced a potentially revolutionary leap in sanitation and hygiene with the launch of a solar-powered toilet to coincide with the launch of the Clean India Mission.
Eram Scientific has announced the launch of the innovative “electronic toilet” armed with “state-of-the-art technology to address public sanitation challenges.” This product has been specifically modified for use in schools.
Made of mild steel, the enclosure of the toilet is sleek and aesthetically pleasing, the company claims. The unit is self-sustaining and equipped with internet connectivity for remote access.
A user needs to insert a coin to initiate operation of the toilet. Upon the insertion of the coin, the door opens and a light is turned on. The user is even directed through voice commands. Water usage is also automated in this toilet. The toilets are programmed to flush 1.5 liters of water after 3 minutes of usage or 4.5 liters if usage is longer. All these operations are conducted using solar panels making the toilet completely “off-grid.” The toilets to be installed in schools are expected to be usable free of charge.
The solar-powered toilet in schools can prove revolutionary in India. Lack of sanitary facilities in schools in semi-urban and rural areas is among the leading reasons for parents not sending their children, especially girls, to the schools.
A recent report filed by a leading Indian newspaper claims that the Directorate of Education found that several schools in India lack adequate number of toilets for their students. One of the girls’ schools in the national capital Delhi has a ratio of one toilet for 1,669 students. Boys’ schools fare only marginally better.
Officials of the Directorate say they usually aim for a ratio of one toilet per 100 students but would strive for a short-term target of one toilet per 140 students. Non-government organisations are hopeful that following this survey by the Ministry of Human Resources and the launch of Prime Minister’s Clean India mission there will be a significant change in the ground-reality. Technical advances like the solar-powered toilets launched by Eram Scientific can certainly play a crucial role in this regard.

The hidden budget nasty
Dear NEVILLE,
Every parent knows that feeling of relief when their child turns 6, because the work of a parent is over. Little Timmy or Susie are ready to go out into the world, earn their keep, and make their family proud. Or does that sound wrong to you? Because the Abbott Government is trying to ram legislation through the Senate next week that would cut off family tax benefits for low and middle-income families when their youngest turns 6 — with more than a decade of clothes, books and food to buy (and man, can they eat). This hidden budget nasty hasn’t got a tonne of attention, but will have a devastating impact on over 700,000 Australian families1. Labor and the Greens are dead set against the change, so it’ll all come down to the senate crossbench next week and it’s very unclear where they all stand. But there’s one thing we do know: when GetUp members have contacted their senators on this unpopular budget, they’ve listened. Letting them know right now that this matters to their voters could make all the difference. How do we know how important family tax benefits are to working low-income families? Because GetUp members have already stepped up to tell their senators, in submissions to a committee reviewing the legislation. Here’s what Kat from Queensland told the committee: “the Family Tax Benefit B represents around 12% of my total weekly budget/income. The impact of removing this single piece of financial assistance will hit my family very hard. Kids don’t stop eating and growing once they turn 6.” Plus, the numbers don’t lie: the loss of Family Tax Benefit Part B would cost families about $3000 a year.2 And the Australian Council of Social Service (ACOSS) and the National Centre for Social and Economic Modelling (NATSEM) have shown that these tax benefit cuts will fall hardest on the poorest families.3 Due to overwhelming opposition, the Abbott Government was forced to break their social services legislation into pieces. But since then, the family tax benefit legislation has been rushed through the House without any debate, in a cynical attempt to keep the senators in the dark on the damaging impacts it will have on Australian families. Undecided politicians? A critical vote just days a way? It’s a moment built for the magic that GetUp members bring to politics. Can you take a few minutes to tell your senator about how important it is to retain this family benefit, and not to slug working families with an unjustified tax increase? http://www.getup.org.au/family-tax Thanks for all you do, References |

The phantom El Niño continues to hold sway over the weather and climate world, in part because it has such a strong influence on weather patterns around the globe. But the weather it influences isn’t the end of the story or even the biggest point. What really matters is how those shifts can lead to flooding or drought.
A new study looks at those downstream effects of flooding in particular and finds that nearly half of the world’s land areas experience a shift in the odds of flooding during El Niño (or it’s opposite phase, La Niña).

That means some areas are exposed to higher flood risks, endangering infrastructure and people, while other areas get a reprieve. Those findings, published Monday in the Proceedings of the National Academy of Sciences, provide a more detailed look at the next level of forecasting.
“A lot of scientific effort has been put into modeling physical hazards themselves. Only much more recently have we started looking at the damage and being able to model that damage,” said Philip Ward, a researcher at Amsterdam Global Change Institute who led the new study.
Ward and his colleagues found that 44 percent of river basins around the world saw changes in 100-year flood risks during El Niño or La Niña years, with some seeing higher risk of floods and loss of property and some seeing lower risk.
The Southwest U.S., parts of southern South America and the Horn of Africa saw some of the biggest increases in flooding risks while the West Coast, Sahel region of Africa and Australia saw the biggest decreases.

Those patterns reflect the broad changes El Niño, known more fully as El Niño-Southern Oscillation or ENSO, generally causes to precipitation patterns globally. The warming of water in the eastern equatorial Pacific that characterizes El Niño tends to shift the odds of precipitation in certain places around the globe, though it by no means guarantees it.
“There have been studies (showing) that some areas get more rainfall during El Niño years, but more rainfall doesn’t necessarily mean more floods. So we’re looking at the actual flooding and damages caused by flooding,” Ward said.
The flood risks Ward modeled are roughly in line with those precipitation shifts, but they don’t always line up. For example, the Southeast U.S. is generally wet and cool during El Niño, but Ward’s study found that although the odds of flooding were increased in some parts of the region, the impact of flooding across the region as a whole was minimal.
You can think of this process like subbing in a speedy pinch-runner in baseball. The pinch-runner may up the odds of being able to steal a base safely but there’s no guarantee they’ll be able to, let alone eventually be able to score a run.
The reason? A lot of factors have to line up for more rains to lead to more floods to actual impacts on society. Flood protection levels, which the study did not consider, and the amount of people living in flood plains as well as other factors further influence the impact flooding can have.
The study provides crucial context for El Niño for the insurance industry, disaster managers and even local communities.
“We’ve been discussing these results with them for re-insurance (purposes),” Ward said. “You can imagine what this study shows to them that the portfolio of risk is not constant through time. There may be some years where they may have a higher risk and more payouts.”

Moving from seasonal rainfall forecasts to on-the-ground impacts is also something the Red Cross is studying. Maarten van Aalst, who heads the Red Cross/Red Crescent Climate Centre, said some humanitarian efforts have already used seasonal forecasts to successfully plan for the disasters, with the most notable example being advanced preparation for major floods in West Africa in 2008. Using a seasonal forecast to pre-position supplies helped the Red Cross cut down response time to just 2 days from 40 days and costs 30 percent less than responding after floods hit.
“This paper demonstrates quantitatively what we have felt intuitively for several years: humanitarian action can be improved by making better use of seasonal climate forecasts,” van Aalst said in an email. “Anything that brings us closer to the real impacts that people experience on the ground (floods rather than rainfall) can lead to better thresholds and sharper planning.”
Ward also emphasized that beyond these opportunities, the study showed that some locations around the world can actually benefit from reduced flood risks during El Niño or La Niña years. Of course in locations that badly need rain, such as parts of northern California, that’s of small consolation with this year’s impending El Niño.
Beyond the here and now, the findings could take on importance in a changing climate. Some research has indicated that climate change could double the likelihood of “super” El Niños like those that formed in 1982-83 and 1997-98. The 1997-98 El Niño was responsible for an estimated $35-45 billion in damage and 23,000 deaths worldwide. Any shift in El Niño patterns could lead to larger variability in flood risks around the globe.
“The paper provides strong evidence that ENSO-related factors need to be studied and mapped to flood risk across the world. Such an effort would lend potential predictability to flood risk, and permit better local flood risk planning as well as portfolio risk management across many locations,” said Upmanu Lall, the head of the Columbia University Water Center and reviewer of the paper prior to publication.
Lall cautioned that more work needed to be done, though, before the paper’s findings could be turned into actionable forecasts.
