Water & Sanitation MDGs - Impetus Needed!

The World Bank has a fantastic database with reams of data.  After seeing how successful World Water Day was this year, I wanted to look at how LDCs in Africa are progressing towards the targets for water and sanitation set under Millennium Development Goals (MDGs).

Adopted by world leaders in the year 2000 and set to be achieved by 2015, the MDGs provide concrete, numerical benchmarks for tackling extreme poverty in its many dimensions.  As we have had 11 years to reach these goals, I investigated how "well" we are doing in achieving them.  More info on the MDGs here.

The MDG in question is number 7: Ensure environmental sustainability, and more specifically Target 7c: Reduce by half the proportion of people without sustainable access to safe drinking water and basic sanitation.

The World Bank database contains data on the % of population, by country, who have access to water and sanitation for the years 2000, 2005 and 2008.  I calculated what the % in 2000 needs to reduce to in order to meet the MDG by 2015.  Then, knowing what this target % needs to be, I calculated how far the countries have come towards meeting that target.  

For example, if in a country 40% of its population didn't have access to clean water, this figure would have to fall to 20% by 2015 to reach the MDG.  If it currently has only fallen 10% (to 30%), then that country is 50% of the way to meeting the target.


Average of LDCs in Africa (weighted by population):
 

2000Target by 20152008% Complete
Without Access to Sanitation77%39%73%10%
Without Access to Water52%26%46%22%

As you can see, LDCs in Africa are only 10% towards achieving the goal for sanitation and 22% for water - not good.


This gives a high level picture, now I wanted to investigate how each individual country is doing in terms of its water and sanitation MDGs using motion charts.  The google doc with the chart is saved here.  The motion chart is on the "Motion Chart" sheet.  Set it up as follows:
  • Y-axis set to "Water - Progress to MDG"
  • X-axis set to "Country Code"
  • Colour set to "Country Code"
  • Size set to "Population"
So what we have now is a bubble for each LDC in Africa, the size of the bubble is proportional to the population and its position on the y-axis is the % towards reaching its water MDG. (Feel free to ask questions on how to work the Motion Chart if the above isn't clear)

Looking at water 1st, the below chart shows the % towards the water MDG each country has achieved from 2000 to 2008:

As you can see, small nations such as Malawi, Lesotho and Gambia are doing excellently.  Malawi, which is the highlighted country above, is 92% of the way towards reaching its MDG for water.  On the other hand, conflict nations such as Rwanda and Sierra Leone have actually gotten worse when it comes to access to water.  The small orange bubble at the bottom of the chart is Sierra Leone, where the access to water has decreased by 27%.


Sanitation, unfortunately, shows an even bleaker picture:

Here you can see that the majority of countries have made little progress towards reaching their sanitation MDG, with the vast majority lying around the 10-20% mark.  Populous countries such as Ethiopia, Sudan and Tanzania achieve scores of 9%, 0% and 0%, which bring down the average mark to 10%.


On a positive note, Angola (the highlighted country above) has made decent progress towards its sanitation MDG achieving 57% of it by 2008.  This is valuable information, as whatever policies they are enacting in Angola are significantly improving the access to sanitation.  It would be great to hear from someone who has experience of working on sanitation in Angola.  Please, tell us how they're doing it so other countries can enact similar policies!

Markets Save Water

Markets can have a bad name.  People talk of asymmetry of information leading to participants being taken advantage of, regulations intended to protect such participants failing and speculators distorting the prices.

All of the above have seen to be, on occasion, true and I agree - markets are in no way perfect. However today I saw a talk on TED that showed markets can serve a purpose - they can save water.

In the talk Rob Harmon explains that you can use markets to keep water in streams and rivers.  His project happens in America, where people can have "use it or lose it" rights to water.  If you don't use the water you have a right to, you can potentially lose your right to in the future.  This, of course,
 leads to hoarding and wasting of the precious resource.

Rob developed a market place where companies that want to reduce their water consumption can pay these individuals to NOT hoard/waste the water, and leave it in the stream.  Everybody wins - the company "reduces" their water consumption, the individual receives money for not hoarding/wasting their water and society now has water gushing through it's streams.

The idea here is identical to the European Union Emissions Trading Scheme, where companies that want (or more correctly "have") to reduce their carbon footprint can pay developing countries not to produce carbon they otherwise would have.

It's an intriguing concept, and one must think of potential uses elsewhere - As opposed to other, shall we say "less friendly" alternatives, Egypt could pay Ethiopia to leave water in the Nile, Iraq could pay Turkey to leave water in the Tigris.  Yet again, everybody wins.
