The sun eventually decided to start (the) spring season (in May!) and blessed us with this kind of weather today:

(…while Nairobi is blessed with rain, rain, rain, rain and rain? Haiiyaaa..)

Which reminded me of a solar panel my mzee bought for me way back in 1989. Back in those days, there was a shop on solar and other alternative energies next to his place of work – so whenever I visited him @work, I spent hours in this shop admiring all these “new” technologies.
My father, knowing that I would one day end up doing something fundi-styled, put his hands deep into his pocket and coughed up this really high-tech (=> 1989!) monocrystaline solar panel for me which delivers 8V and a current of 165mA.


And yes, children LOVE “solar models” :-)

trashtoys ‘r’ us

Earlier in Januar 2006, the ecoblog Treehugger covered an interesting story on Arvind Gupta who is well known for developing toys out of trash / waste material and publishing books on various subjects. The “tinkerer and toy-maker”, as he is quoted in this article by India Together, has dedicated his life to demystifying the abstruse world of science for the comprehension of children”.
Looking at his toys, one understands his interesting approach on combining toys & with science and it also reminds me of this little scientific book I had as a child that featured similar ideas. No wonder I’ve become a geek :-)

“The best thing a child can do with a toy is break it !”
(quote on Arvind Gupta‘s website)

This morning I received a challenging short message by my dear friend Mbuzimoja, who asked me about creative toys that could be built with 4 to 9 years old children in an orphanage. Since I’d forwarded the above mentioned article to her earlier in January, she told me to have a closer look at do-able ideas – toys that could be produced in Kenya. Oh yeah – I DO like this idea!
Here’s what I had in mind (all links open in a new window):

Crown-Cap “Tik-Tiki”


Ballon Pump

can top

clap in the air (oh, i love this! :-)

musical oboe

Or for the older kids a simple generator (motor) that powers an LED (these parts are available on 2nd hand electronic markets or even from other old electronical gadgets).

…the list goes on and on and it becomes obvious that creativity knows no boundaries while at the same time the children learn something about building their own toys (like those wire cars we already know) and getting an understanding for technology. In case this triggered your interest, make sure to check out Arvind Guptas publications as well. A man who clearly enjoys the joy of sharing. Thank you!

P.S.: and here’s a special solar link for you, afroM :-)


“There is no doubt that the market has spoken in a big way.
This leaves no doubt in the capacity of our economy to finance well-structured viable ventures”

Esther Koimett, Investment Secretary, as quoted in today’s DN on KenGen’s IPO.
I am not such an expert on private investment like Bankelele and his commentators, who are btw doing a great job in reporting stories from the monetary world in Kenya. What triggered my attention on the KenGen IPO, though, was that Kenyans apparently come out in great masses when it comes to investing money in (hopefully) profitable markets.

I was also going through an interesting advertisment (published in April 11th edition of the DN) on the launch of the Kisumu Water and Sanitation Project which is partly funded by the French Government through AFD – an investment to the tune of 20 million Euro.
Now, bearing in mind that people are willing to spend their savings on shares – an investment that promises a healthy divident in future, what if we take this kind of investment spirit onto different levels? So far, it seems, ppl are willing to invest their money into anything profitable – so why does the Governemnt have to look for funding if Kenyans actually do have the money needed to …repair Kisumu’s water supply and sanitation services?
All four speeches on the launch of the above mentioned project agreement held by the Minister of Water and Irrigation, his P.S., the chairman of Kisumu Water and Sewerage Company Ltd. and the Mayor of Kisumu contained a phrase in which they encouraged all involved parties to “embrace good corporate governance” or even a straight-forward challenge to the Water Services Board & – Provider “to live up to the expectations”. And, according to the P.S., “the support has attracted the Global Partnership on Output Based Aid (GPOBA) funding which if used properly should solve the problem of water and sanitation in low income areas”.
It is great to see this kind of progress since the implementation of the Water Act 2000, and a Ministry that is actively encouraging the people to greater achievements.

And as much as these new funding approaches (like GPOBA, Infraco or Guarantco) are interesting, what I would like to ask instead is: Are ppl ready to accept a completely different approach on the way we see water and sanitary needs under a financial context? What (for instance) if we can find ways to succesfully implement even more EcoSan projects in Kenya where human excreta and waste water become nutrients that could then be sold for agricultural use (~fertilizers)?

Or in other words: our waste => money.

The technology is already available, the understading for closing environmental loops is currently being thaught to future generations and the monetary incentive is given. So, what do you think? Would it be possible to attract ppl in investing their money into such unorthodox businesses that do not only fill the pocket but also help closing some much needed environmental loops?

Googleardhi, part 5

Having blogged about Google Earth before here, here, here and here, there’s something new to add, something we’ve all been waiting for: new maps!
I don’t know if all these maps are THAT new – but they are more detailed at least.
I read a story on a german IT website about GoogleEarth doing this for Germany, and so I thought I better check Kenya as well. Et voilà, our new Nairobi map:
Cool! (dito Eldoret Airport, Kisumu, Mombasa Airport (MIA), etc. :-))

As for Germany, some maps improved, some were edited or even worsened while others are just horribly detailed.

That red object is my ‘89 VW Golf II in front of the house….go figure…


World Water Day 2006

  • 1.1 billion people lack sufficient access to safe drinking water.
  • 2.6 billion people lack access to basic sanitation.
  • 6,000 children die every day from lack of safe water or poor hygiene.
  • On average, African and Asian women have to cover 8 kilometers a day to get fresh water.
  • The average African lives with less than 20 litres per day while the average European consumes more than 150 litres daily and the average North American more than 300 litres.
  • 4 billion hectares, representing 1/3 of the emerged lands of the globe, are threatened by desertification.

Today is the World Water Day 2006 and I will take this opportunity to inform my esteemed readers of a water related project to contribute my share on this topic:

The United Nations Educational, Scientific and Cultural Organization (UNESCO) is this years UN agency to coordinate events surrounding World Water Day (WWD) around the world – and this years theme is "Water and Culture". Well, water and culture? What does that mean?

According to the director general of UNESCO, Mr Koïchiro Matsuura, "technology alone will not lead us to viable solutions" on the world’s urgent water problems but instead "we must better understand the complex interactions between societies, water and the environment". And he goes on saying "water management itself needs to be understood as a cultural process….(…) …The nexus between culture and nature is the avenue for understanding resilience, creativity and adaptability in both social and ecological systems."

Or, to put it in my words: in order to have a positive impact on the world’s urgent water problems, we can not just apply various technologies while hoping that things might work out. Instead, we first of all need to comprehend the connection between the environment and our social systems. Of course, a relatively simple approach – which is still often neglected.
The basic idea behind this is to identify a causal framework which will help to deal with the various and complex water problems the world is facing today and in the future. And this is where the UNESCO’s programmes come into limelight:

The UNESCO, which btw celebrates it’s 60th anniversary, started developing international projects and programmes to improve our understanding and management of the earth’s resources.
One of these projects I would like to focus your attention on is the "from Potential Conflict to Co-operation Potential" initiative – which is one of UNESCO’s International Hydrological Programme (IHP) contribution to the World Water Assessment Programme (WWAP) in cooperation with Green Cross International (GCI).

Over 260 river basins are shared by two or more countries. To date, the UNESCO’s International Shared Aquifer Resource Management project (ISARM) has inventoried over 150 shared aquifer systems with boundaries that do not correspond to those of surface basins. Approximately one third of those basins are shared by more than two countries, and 19 involve five or more sovereign states. Of these, one basin – the Danube – has 18 riparian nations. Five basins – the Congo, Niger, Nile, Rhine and Zambezi – are shared by nine to 11 countries. The remaining 13 basins – the Amazon, Aral Sea, Ganges-Brahmaputra-Meghna, Jordan, Kura-Araks, Lake Chad, Mekong, Neman, La Plata, Tarim, Tigris-Euphrates and Vistula (Wista) – have five to eight riparian countries.

The PC-CP project addresses the challenge of sharing water resources and its role is to help water resources management authorities to tip the balance in favor of co-operation potential away from potential conflict.

For its current 2nd phase, PC-CP has determined the following operational objectives to strengthen the capacity of the target audience in dealing with potential and actual water conflicts :

  • The development of educational material related to conflicts and cooperation in the field of shared water resources;
  • The development of appropriate institutional frameworks for the anticipation, prevention and resolution of water conflicts;
  • The development of methodologies for conflict prevention and resolution;
  • The improvement of legal tools for the management of shared water resources;
  • The development of a comprehensive information system on water conflicts and cooperation;
  • The dissemination of results and best practises at a global level.

So the bottom line to all this is that there are good and well elaborated programmes and projects in the pipeline that include a more holistic approach to today’s water problems. I am specially interested in the development of a comprehensive information system, and maybe today’s blog on this matter has slightly contributed to informing the public about these issues.

Please don’t miss today’s launch of the 2nd United Nations World Water Development Report (WWDR2) in Mexico City, Mexico. Thx! :-)

sanitation is dignity

gto2.jpgThe german print media recently covered the interesting initial public start of an international organization – the German Toilet Organization (GTO) – here in Germany which main objective is to lobby for more (public) toilets and improve access to clean sanitary needs worldwide (the pic to the left shows the recent “sanitation is dignity” exhibition on Potsdamer Platz in Berlin, Germany as organized by the GTO – pls click to enlarge).

Toilets, choo, restrooms, latrine, lavatory – you name it.

Well, you name it? What kind of words do people use when they try to express their need to “take a natures call” or have to relieve themselves? The problem starts with the fact that we – we as in people world-wide – don’t even like to talk about these issues. It’s a taboo that keeps on being ignored, yet going to toilet is just as natural as eating or sleeping. And in order to improve the sanitary situation worldwide, first thing we need to do is to start talking about this issue.

The shocking truth is that, according to the WHO and UNICEF, roughly 2,6 billion people (around 42% of the worlds population) don’t have access to a working (read: adequate) sanitary system – and with an ever growing population and a clear need for an improvement, something has to be done. Soon.

“Proper sanitation protects water resources, increases health, provides dignity, increases agricultural production, can be an energy resource”….wait! It increases agricultural production? How come?

The problem with waste water treatment in huge treatment plants starts with the initial problem that we – the users – flush down virtually anything down the toilet. Out of sight, out of mind? Maybe… However, the results of these daily actions are that we get to have this huge mixture of waste and nutrients that require a lot of process engineering and energy to be separated.

==> We are using electrical energy to treat our waste. How crazy is that?

Now, what’s with that argument that an improved treatment could increase agricultural production? Let me please (try to) explain:
Instead of re-thinking complicated and expensive ways on how to separate this horrible mixture, let’s directly go to the root of the problem and separate the urine from faeces and greywater where they are being mixed up: at the toilet. There are some toilet designs out there that come with a built-in separation system – just think of a bowl that has an extra outlet for the urine and you get the idea.
By doing this, we receive an almost homogeneous, separated material out of which we can then recover nutrients, trace elements and even energy. Think of phosphor, this fertiliser stuff we put on our fields & gardens: the world-wide resources are limited, yet some countries (like Nepal) still invest a lot of money to import it although we could just recover up to ~40% of that phosphour from our urine.


In fact, the German Agency for Technical Co-operation (GTZ) started (among others) an initiative to promote this idea of closing nutrient loops some years ago and have shown great progress in promoting this much needed approach to fulfill the Millenium Development Goals set by the UN. They call it ecological sanitation (ecosan) and to emphasize a systematical approach to this paradigm shift, they have published a source-book (PDF, 9 MB) as well as other useful information material that will help to promote this great idea of ecological sanitation.
Mind you – ecosan isn’t just a technology or a technical approach to bugging issues. It’s a philosophy and understanding for the challenge which we’ll have to face in the 21st century: closing biological cycles/loops. Among the key issues of ecosan as documented in the so-called Bellagio Principles, we find the following definition:

Waste should be considered a resource, and its management should be holistic and form part of integrated water resources, nutrient flow and waste management.

• inputs should be reduced so as to promote efficiency and water and environmental security
• exports of waste should be minimised to promote efficiency and reduce the spread of pollution
• wastewater should be recycled and added to the water budget

And yes, I am very passionate about this subject and as I’ve mentioned earlier, the challenge I see for us in the 21st century will be to re-design the products and technologies we’re using on a daily basis so that every material remains in a biological or technical loop / cycle. No more end-of-pipe technologies but cradle-to-cradle designs with materials that remain as nutrients to future generations. There is so much technology out there and it starts with generating an awareness for the biological cylce – something our forefathers already knew and we apparently forgot with todays products. Also, this isn’t just one of those ideas for the drawers of development aid – this is an approach on a global basis that sees various implementations in e.g. Europe as well as in Asia or Africa. The technology is already applied – even in Kenya – and in fact, I am planing to promote this even more when I am back in Kenya.
