IRIN reports on new levels of water rationing in Yemeni cities.

“Water and sanitation companies in Yemen are adopting unprecedented water rationing in major cities”, reports IRIN in a recent article.

Price hikes, rising demand, and decreasing precipitation has brought the situation to a critical head.  Estimates place Yemen’s water deficit at 1.28 billion m³.

The impact on local residents has been huge.  One resident reports,

Our household has received no water for 21 days, so I turned to buying water from trucks… In the past month, I bought water four times, costing me YR10,000 [$50] – nearly one-third of my monthly salary.

Is this a sign of things to come in other parts of the arid world?

Water crisis = food crisis

When water availability diminishes, food crops tend to suffer.

TreeHugger has an excellent discussion of the impact of drought on food production in Australia.

Rice is a water intensive crop, and when drought hits, production suffers.  In Australia, “production has dropped from 1.6 million tons in 2000 to a mere 18,000 tons in 2008.”

This has important implications for planning for climate change.

Taking the experience of Australia to heart now can help other areas be proactive about water use and avoid sharp changes in agriculture, and therefore economy, such as what Australia is now facing. Getting started today and reduce our water use to only what we need as well as make practical decisions in the agricultural sector, can help a region avoid a more dire crisis in the future.


IFTF 10 year forecast: Environment, the Blue Economy

May 19, 2009

enviro

We continue our series reviewing key themes from The Institute for the Future’s latest 10 year forecast.  In this post, Environment: The Blue Economy

The next theme we will be reviewing from the IFTF’s new 10 year forecast is that of Environment.

This is one of the more interesting themes to emerge from their 10 year forecast.  On the environment, the IFTF writes,

The oceans become the focal point of economic development and environmental debate, as we struggle with collapsing fisheries, a search for new energy sources, and large-scale interventions in global climate climate change.

Detailed sub-themes from this concept include:

  • New coastal zone materials: the rush to solve problems of rising sea levels and coastal climate events drive the development of new materials – many based on materials and life forms that occur naturally in coastal areas.
  • Deep, deep ocean drilling: in the search for new sources of fossil fuel, engineers go much deeper into the ocean floor – with uncertain results.
  • Renewable ocean energy: new technologies for hydrokinetic (or wave) energy and ocean thermal energy conversion get on the fast track to development as a means of reducing carbon emissions.
  • Collapse of fisheries: climate change and over fishing threaten the viability of global fisheries, and drive new certification practices for sustainable fishing.
  • Coastal ecosystem services: urbanisation, industrialisation, and climate converge in coastal zones, where measurement of ecosystem services will play an increasingly important role in everything from development and insurance to disaster management.
  • Ocean dead zones: large low oxygen zones appear to be recurring with regular cycles now of the West Coast of the United States, which scientists attribute to climate change.
  • Methane scares: rising temperatures may contribute to rapid release of methane – a far more destructive greenhouse gas than CO2 – trapped in permafrost and the ocean depths.
  • Geo-engineering climate change: as the ocean’s capacity to regulate climate change declines, extreme geo-engineering measures – from ocean fertilisation to very large scale thermal pumps, enter the debate.
  • Golden age of oceanography: ocean crises, plus low-cost, sensor-based data, genetic mapping of ocean species and the growth of amateur and NGO ocean scientists accelerate the evolution of ocean science.

This theme points us towards the often ignored, often undervalued, yet completely essential aspect of human life; the ocean.  We find the discussion of how ongoing political and technological dilemmas on land translate into policy, debate, and action on the seas to be fascinating; not least of which because the geo-political dynamics become much more exciting, and, well, fluid (sorry the pun).

I was surprised not to see piracy on the list as well, however.  No mass migration of urban populations as coastal cities become uninsurable or uninhabitable.  But a fantastic mix of issues to consider, reminiscent of a recent HFP scenario on water pollution, urban growth, and state conflict in the ECOWAS, by HFP consultant Noah Raford.

As always, thanks to The Institute for the Future for these inspiring themes from their latest 10 year forecast.

GPS accuracy could start to drop in 2010

May 17, 2009

gps

A new US GAO report has found that organisational factors in the US Air Force’s contracting and budget management process may result in decreased accuracy or even failure of the global GPS system, starting in 2010.

From the report:

The Global Positioning System (GPS), which provides positioning, navigation, and timing data to users worldwide, has become essential to U.S. national security and a key tool in an expanding array of public service and commercial applications at home and abroad. The United States provides GPS data free of charge. The Air Force, which is responsible for GPS acquisition, is in the process of modernizing GPS. In light of the importance of GPS, the modernization effort, and international efforts to develop new systems, GAO was asked to undertake a broad review of GPS.

The report reviewed the Air Force’s replacement programme for the ageing GPS satellites and that,

“If the Air Force does not meet its schedule goals for development of GPS IIIA satellites, there will be an increased likelihood that in 2010, as old satellites begin to fail, the overall GPS constellation will fall below the number of satellites required to provide the level of GPS service that the U.S. government commits to. Such a gap in capability could have wide-ranging impacts on all GPS users, though there are measures the Air Force and others can take to plan for and minimize these impacts.”

It concludes, “it is uncertain whether the Air Force will be able to acquire new satellites in time to maintain current GPS service without interruption. If not, some military operations and some civilian users could be adversely affected.”

Commentary

We have become so dependent on GPS in many ways over the last 5 to 10 years.  Crowd sourced crisis mapping, rapid disaster response, and large force co-ordination all depend on GPS and location awareness abilities.

I would love to see a scenario play out whereby aid, development and military organisations invest increasing resource on such advanced location aware technologies, only to have them fail or decay.  What would such a scenario look like?

Obviously the US military won’t let the system fail.  A commentary on TidBITS writes that, “even if the satellite constellation drops below 24 satellites, that doesn’t mean that GPS service will fail altogether. It does mean that the level of accuracy that both military and civilian users have become accustomed to – which is actually higher than promised – may degrade significantly.”

Alternative systems also may come online in the coming years.  The EU is developing a civilian GPS system called Galileo, scheduled to come online in 2013, and the Russian GLONOSS system may be repaired as well (the system was developed in 1995, but fell into disrepair due to lack of funds.  It has been promised to come back online by 2010, but there are doubts about this).

It is likely that the US Air Force will fix the system before disruptions become critical.  It is also likely, however given the history of bureaucracy and budgetary inflation at the Pentagon (see the F-111, B-1, or F-15 debacles for case studies), that these repairs won’t be done in a timely or efficient manner, but only at great expense and with great fanfare and inefficiency after the fact.


New Hans Rosling video at TED on the HIV epidemic

May 15, 2009

Hans Rosling, of GapMinder fame and earlier posts, just debuted a nice new video demonstrating the spread of HIV virulence in the world.

Vodpod videos no longer available.

Rosling demonstrates how the truth behind the data is often more complex than it seems.  He uses the examples of Tanzania and Kenya, which have a dramatic variation in HIV incidence rates between the wealthy and poor (with wealthier Tanzanians remarkably more infected than the poor) and even with a country (with a single Kenyan province accounting for the vast majority of HIV infection rates).

This presentation raises a few extremely important points, with which readers of this blog will no doubt be familiar:

  • Resolution matters: Issues of data availability are endemic to development, but making policy and plans on averages is always, always, always a bad idea and invariably produces a poor understanding of reality.  This is true in spatial terms (Kenya) and social terms (Tanzania).  I would add temporal terms as well.
  • Visualisation matters: Even if you have the best data in the world, how you manage and present it makes as much, if not more, impact than the data itself.  Rosling is a master at this, a la Tufte in his earlier days.
  • Narrative matters: The impact of the data and the visuals are only as good as the narrative understanding that draws them together.

An excellent presentation as always.  I wish all development briefings were this clear.


Hans Rosling Video Gapcast: Swine Flu News versus Death Ratio

May 11, 2009

Hans Rosling, of Gapminder fame, recently posted a humorous and perspective-inducing video comparing the number of deaths from swine flu to those from tuberculosis.

Vodpod videos no longer available.

The famous Swedish statistician compares the amount of media coverage for swine flu to that of tuberculosis, normalised by the number of deaths caused by each in a two week period.

Obviously swine flu has pandemic potential and could still make a break for the big time, in substance if not in coverage alone.  But this is nonetheless a lovely measure of calm in the midst of an otherwise pandemic-crazy,  catastrophe prone outlook.
