Toilet Revolution: Shyama V. Ramani at TEDxMaastricht

Mon, 16Sep2013 Comments off

This is one of the best Sanitation/ Global Health stories we have seen lately. Delivered in a  very pleasurable consumable format, by a great speaker who make the topic reachable to a board spectrum of professionals and people. It’s antidotal in nature, while being universal in the realities of solving a village’s sanitation issues. Shyama has an honesty that needs to be incorporated into the newly developing transparency practices oft the world’s NGOs . This talk needs to be shown to the NGO’s and their altruistic “minions” before they venture out to help their global brothers and sisters.

The story starts out after audience imagining life with out toilets with Shyama explaining how she as pure novice, walks into a coastal village after a tsunami, and realizes she must bring the villages toilets back.

She learns along the way  “…2.4 billion people don’t even have access to a toilet that functions, 1 billion don’t have access to any toilet the just have to defecate anywhere they can …” Thus the “….lack of waste management and toilets is making a killer that we are not talking about enough … diarrhea…. the number one killer in most developing countries…”

She Googles and contacts “experts” to educates herself with the facts to get the job done  or so she thinks.

Upon the last new toilet being being initiated with a squat of a villager behind closed doors, Shyama, unlike many of the NGO’s, does not walked away.  The core of her captivating story is what happens afterward … The door is opened, the veil of naivety is exposed and lifted. Where/when most project fall into failure, she and her partner begins the long diagnostic/prognostic/improvement cycle.

Shyama  reminds us it is a an effort that is ongoing with more to learn and invites us to come back… It will be a crime if we do not see the next installment of this story as it continues to unfold.

Essential and very practical points abound within her story. One that are be showing up in other stories from around the world- and  hopepfully becoming a  din that must be addressed. With some paraphrasing, here are a few I see tucked in her tail:
1 NGO’s can’t do it alone and succeed; the villagers are needed – with a vastly redefined roll for NGOs.
2 Technical experts/ engineers may not be the social experts – both are needed.
3 Toilets at the onset are not alway seen as valuable/desirable assets. Education is needed before during and after
4 Women and men of the villages do not have the same perspective on sanitation. The project must address both separately as well as together .
5 Villages without ongoing support services will quickly have “…fossils of abandoned stinking toilets allover…”
6 Schools as an institution do not just naturally promote and desire ecosan toilets. They must also be nurtured. (details not addressed in this piece – but would be important to learn more about)
7 Building heathy social stimulus/pressure/ pride must be part of the scope
8 People who want the toilet must be educated on use and care
9 The villagers must be part of the economic model – the social model. Such pieces as manufacturing / construction/ distribution/ sales/ support / education/ promotion/ etc
10 Microfinance is a viable solution – (a work in progress in the story)
11 Toilets can provide a financially valuable natural resource – fertilizer
12 This all makes it a slower road, but it is a viable road, unlike the fast road the many NGO’s are building.
13 100% may be the target but  80% is a not a bad number to start with- and even that require lots of work.

Shyama  reminds us it’s a an effort that is ongoing and invites us to come back ,so to speak.  It will be a crime if we do not see the next installment of this story as it continues to unfold.

Rose George: Take toilets seriously talk at TED@London

Thu, 21Mar2013 1 comment

A great video to watch while waiting to see the  recording of  Rose George when she spoke at Ted 2013

 

Profile from TED 2013:

Rose George thinks, researches, writes and talks about sanitation. Diarrhea is a weapon of mass destruction, says the UK-based journalist and author, and a lack of access to toilets is at the root of our biggest public health crisis. In 2012, two out of five of the world’s population had nowhere sanitary to go.

The key to turning around this problem is to “stop putting the toilet behind a locked door,” says George.  Let’s drop the pretense of “water-related diseases” and call out the cause of myriad afflictions around the world — “poop-related diseases” that are preventable with a basic toilet. Once we do, we can start using human waste for good.

George explores the problem in her book The Big Necessity: The Unmentionable World of Human Waste and Why It Matters and in a fabulous special issue of Colors magazine called “Shit: A Survival Guide.”

Among many topics the Doc  weighs pros and cons of of traps to prevent odor and gases for escaping .Most of the solutions  have cost / maintenance barriers that limit feasibility to particular set of cases. India is a large county and need a variety of solutions as does the rest of the world.
We will  will  be interested to learn more about Zerodor
“An odourless trap Zerodor which does not require replaceable parts or consumables resulting in low maintenance costs has been developed at IIT Delhi. This model is in final test stage yet to be made commercially available.”    more on Zerodor
further notes from forward

Waterless Urinals do not require water for flushing and can be promoted at homes, institutions and public places to save water, energy and to harvest urine as a resource. Reduction in infrastructure required for water supply and waste water treatment is also a spinoff arising from installing waterless urinals. The concept, founded on the principles of ecological sanitation helps in preventing environmental damage caused by conventional flush sanitation systems.

In recent years, Human Urine has been identified as a potential resource that can be beneficially used for agriculture and industrial purposes. Human urine contains significant portion of essential plant nutrients such as nitrogen, phosphate and potassium excreted by human beings. Urine and faeces can also be separated employing systems such as urine diverting toilets. In the light of diminishing world’s phosphate and oil reserves which determine availability as well as pricing of mineral fertilisers, harvesting urine for reuse in agriculture assumes significant importance. Akin to the movement for harvesting rain water, urine harvesting is a concept which could have huge implications for resource conservation.
