One house, one buffer

Posted by Francesco Sambalino
May 23, 2013


Djerba from the plane appears as a vast and flat island dotted with sparse settlements and clusters of tourist villages. It is always ready to host hordes of Europeans escaping the colder north. If you go to Djerba - or any other location in southern Tunisia - you will be sure to find plenty of sunshine and mild temperatures. This is often the perfect recipe for a nice holiday.

Less often we think on how the Djerbians deal with a climate characterized by low and unreliable precipitation (250 mm average) and by the absence of perennial sources of fresh water. The written history of Djerba spans back to the time of Homer’s Odyssey where Djerba was the home of the lotus-eaters. The Phoenicians and later the Romans had in Djerba important outposts. But how could they thrive with only a few drops of rainfall? In fact – only in recent years – a pipeline connected the island to the mainland.

The trick is as ingenious as simple. Think about it: two hundred millimeters of rain over 1 square meter of impermeable pavement can yield up to 200 l of water. According to this principle, the Romans - throughout the Mediterranean sea - built their houses with a central courtyard (atrium) surrounded by a slanted roof (compluvium) that would direct the water flow into the atrium were a shallow, usually squared pool (impluvium) would be located (see illustration below). This shallow pool acts as a decoration for the house, but helps in mitigating the temperature during the hot summers as well. The pool is connected to an underground cistern to collect excess water which will be available during the dry season.

Nowadays, Djerbians still collect rainwater in the same fashion.  They use roofs to direct rainwater in cisterns that are built under every building. As a matter of fact, the cistern is built before the rest of the house as shown in the picture below. Only after collecting the first rain harvest, the rest of the house is built on top of it by using the water for its construction. The cistern is not only a big recipient for fresh drinking water, but it also helps in cooling down the apartment from the bottom. This, together with thick walls painted in white, helps in keeping the room temperature down without the need of expensive air conditioning systems.

The people of Djerba have been living and thriving for millennia just relying on scarce rainfall. Now the island has become the favorite holiday destination of many. The tourist resorts became the main water consumers of the island; special conduits have been built from the mainland to bring in freshwater. Freshwater meant to serve the huge swimming pools and refresh the burnt skin of visitors. But still, many Djerbians prefer to rely on their roof and their cisterns. The piped water is in fact salty because of the overexploitation of the coastal groundwater resources and consequent salt-water intrusion (Article). Instead, the water collected with the traditional roof-and-cistern system is sweeter, cheaper and reliable in the years: A simple buffer under every house.



 
To start to exist

Postcard from Tharparkar, the desert on the border of Pakistan and India and one of the hardest places to be:  summers of blazing heat, child marriage as the norm, groundwater in little patches (but often saline), and hardly any rain.

Here (above) is a picture of a large campaign to get women registered, have an identity card and to start to exist.  The identity card makes them a person belonging to a country – entitled to vote, credit, education or ownership of assets.

In each village, a committee identifies women that have never been registered and are 16 and above. Transport from scattered hamlets is arranged to registration camps: an ID is prepared and an explanation is given on what basic civil rights are all about.

Another change – though an awful lot needs to be done – is the improvement of the water supply in Tharparkar.  Many women spend all of their daytime hours collecting water from distant places. Addressing water supply through a range of measures frees up time for a life.

Take the village of Dedh, 45 kilometer from Mithi, the headquarter of Tharparkar District. Around 150 households live in Dedh. Water comes is various ways, but none of them are easy. It is collected from the roof top and from the compound of the primary school, the only concrete building in the village. It comes from a cascade of two surface ponds fed by sporadic rain run-off. The first reservoir traps the sediment. Clean water is conveyed to the second reservoir through a pipe. There is no guarantee that the reservoir fills though, and the rooftop only yields so much.

Then as a third, a unique structure was built constructing an artificial basin of 100 x 100 feet with concrete. The basin leads to a cistern in the centre. This is the system best liked, as it is clean and a little more reliable.

  This is the system most liked by women. They have made temporary plastering of the shutters to protect water theft from the cisterns, and ensure the protection of the recharge area with barbed wire and thorny brushwood.

These are the options for hard places such as Tharparkar and it is great they are being developed through several initiatives. There is something amiss, however, with water supply options such as rooftop water harvesting, surface water ponds and cisterns. Although they make all the difference between a life and drudgery in the most difficult places of the earth, they are often absent from regular drinking water programs. Neither are they counted under Millennium Development Goals targets. The reason: the quality of water made available through such options does not come anywhere near the WHO standards. And so public investment programs shy away from them and go for the safer official systems in the safer areas, leaving out those that need better water most.

Unfortunate.

Open Letter to UNICEF

posted by Frank van Steenbergen

If you would head an organization whose mandate is to protect of the rights of children, help meet their basic needs and raise resources to achieve this..

And if that same organization, upon receiving funds from donors would take between six to eighteen months to get the paper work ready for things to roll out, mainly because of internal procedures and compliance mechanisms (that is what I observed, if it is an odd exception I stand corrected and humbly apologize but I am led to believe it is not exceptional)…

And if you would charge between 7-13% as handling fee on these funds for providing this belated service…

How would you feel?

I for one would not feel good. The reason is that by delaying implementation with say one year several thousand mothers and children have no access to clean water for that one year. This means more diarrhea, more morbidity, more retarded development. I would then not feel proud of receiving a salary upwards of what some heads of state make.

The name of the organization is UNICEF (but it is not the only one) and this open letter is based on several water and sanitation programs I have seen it is entrusted to manage in Africa.  Not only are delays common, what is worse, no one seems be bothered or angry. Obviously it is a much larger crime to break unwieldy rules than to speed up and deliver development to needy people.  It is not unusual that not only starting dates of programs are postponed but also that the time to implement is shortened because first fiduciary (who invented that word!) had to be fulfilled. Here is an issue of leadership and priorities. There is an expression in my country: ‘throwing away the baby with the washing water’, and this is what it is.

Bureaucracy kills.

Good Grab, Bad Grab

posted by Frank van Steenbergen
April 22, 2013

With the large and sometimes overexposed attention for land grabbing in Africa, good examples tend to be forgotten. Here is a picture of an inspection team to a land concession issued five years earlier.

The land is in a remote part of Amhara state in Ethiopia. It is barren and windswept. The concession was given to an investor from the ‘diaspora’ community- i.e. Ethiopians who spent part of their life abroad and are often a source of investment.  In the last five years he has, with moderate success, been trying to cultivate sorghum and ‘teff’ (the nutritious grass crop) on the thin soils. Part of the land concession was the obligation to protect the land and undertake catchment measures.

Here is the inspection team, consisting of representatives of several zonal offices (Agriculture, Investment, Environment), making an unannounced visit – checking whether the promises that were part of the concession have been kept. They were not: the investor admitted that he had not yet undertaken land protection measures. The issue would be settled amicably and without any pressure or back payment. The investor will make a land management plan and implement it. So this would be a very normal small event – how things ought to be and often are.

There is a bigger side to this small event.  Things like this do not appear in the news and are not highlighted. What is highlighted are all things wrong or framed to be wrong. While it is good that there are watchdogs, some bark whenever and one gets the feeling that they are like mastiffs let loose. It is good to be critical, but good to be positive as well and not automatically damage a country’s reputation.

Of late, I have been reading a report called ‘Diagnosing Corruption in Ethiopia:  Perceptions, Realities and The Ways Forwards for Key Sectors’. If you read the title it suggests there is much amiss, yet if you read the content there is the normal and healthy worry but also the observation that Ethiopia does much better than other countries. The question of course is why that message does not make it to the cover.

There is a section in this book on corruption in land management. The report, commissioned by World Bank and the Federal Ethics and Anti-Corruption Commission (FEACC), finds that corruption risks in land management in Ethiopia are increasing because of a weak policy and regulatory framework on land allocation, titling, and management. This gives scope for lots of local mishaps. In spite of this, there are other things that go well, such as land inspections like the one described above.

This raises another issue related tp land grabs. Often it is portrayed in conspiracy terms: of a new form of colonialism driven by newly emerging and natural resource constrained powers, trying to secure the world’s last land frontiers. However, what I observed first hand is another problem. What is often forgotten is the clumsy and dangerous opportunism in land grabs.  This can be a market businessmen in Addis getting hold of several 1000’s hectares of land in a remote part of Ethiopia without having a basic clue on how to farm, or Spanish building contractors in Mauretania in the same league, trying find another pursuit with the construction industry in doldrums.  Such opportunism does not necessarily create an unbalanced world, because these are the land grabs that fail. However they do much damage because in the course of the ill-planned adventures they forest, land and water resources in some still-pristine areas gets destroyed. In line with the recommendation of the ‘Diagnosing’ report, what is required is a better managed and better planned development of land, not a polarization of the issue.
