[Stoves] Cleaner cookstoves might benefit Mozambicans - environmentalresearchweb

Paul: (Responding to an old post where you said "once again major money for
a research project without including the woodgas stoves,,,"

Precisely.

Money put to servicing propaganda and brainless research on cleaner stoves
- whatever that means to whomever - has opportunity costs: time and money
lost to serious stove/fuel testing and design changes toward greater
usability.

>From Esther Duflo's takedown - in 2014? - of "improved stoves" in Odisha,
India using stoves that the designer had disowned to the Malawi "study" of
Philips stoves to this Mozambique paper (whose earlier version I had
privately criticized), the mushrooming literature on "health benefits" of
cleaner cookstoves has deteriorated from the pathetic to the pathological.

All for the sake of churning out pal-pleasing papers for the gullible. To
generate hysteria among the easily excitable. (Not me.)

Has GACC raised and spent even $10m on new stove design and contextual
testing or fuel characterization? What did all the reports it commissioned
from Accenture or Dalberg achieve? Get more money from Global Canada and
DfID it is not accountable for?

Call a spade a spade, not a heart or a diamond. Swooning over experts - or
WHO - is politically correct, but suicidal for biomass/coal stovers.

Or have we all decided to go numb and be opiated by WHO, giving ISO
exercise totally undeserved deference and staying silent while a life is
prematurely lost every few seconds (as WHO claims)?

Does anybody on this list seriously believe that ISO standards and tiers
will lead to a revolution in markets for improved, fortified, enriched,
small, inherently safe, affordable nuclear reactors - oops, I mean better
biomass stoves?

If so, I would like to know the reasons. I don't think even GACC CEO
believes it any more.

Time to go back to the drawing board (at least for those of us who don't
have to sweat like you or Crispin to popularize proven designs)

Boil blood, not water.

Should we try to bring "Domestic Energy" and "Human Environment" together
in "Modernizing Energy for Human Environments", instead of just measuring
fuel efficiency and PM 2.5 emission rates to please TC 285 and WHO?

Stovers,

I looked at the report.   4 stoves
1.  Natural Draft
2.  Forced air
3.  Charcoal
4.  LPG

What stoves do you think they were testing.   Not what I thought.

1.  Natural Draft   ----  An Envirofit Rocket stove
2.  Forced air    -----   Biolite fan-assisted ROCKET stove
3.  Charcoal     -------  Envirofit charcoal stove
4.  LPG     ------      Envirofit LPG stove.    Yes, Envriofit is into the
LPG stove business

Great.   It is good that they had improvements.

But note that there were no TLUD stoves.

So, once again major money for a research project without including the
woodgas stoves that are in the modern and advanced stove types* as
classified by the GACC and the World Bank ESMAP program* (see my 4-page
summary of "Classification of Stove Technology and Fuels" at

Here’s a report on an interesting study that Nikhil found on the
Environmental Research Web. The model projects a positive health impact
from a marginal intervention with improved stoves, which is probably an
accurate reflection of what stovers see as a result of their efforts:
better stoves improve health. While Nikhil has bashed this modeling for its
precision, the trend would likely be the same for alternative models. We
can always find better metrics to support our work, or to find fatal flaws,
but let’s do it working together in positive collaboration without the
trash talk that we’ve been hearing for several months. This forum is not a
complaint desk or a political blog.

*Cleaner cookstoves might benefit Mozambicans *

By John Cartwright

Cleaner cookstoves could improve air quality and health, and reduce
temperature rise from climate change in Mozambique
<http://iopscience.iop.org/article/10.1088/1748-9326/aa5557>, according to
a study by researchers in the US.

The findings reinforce the health dangers of cooking with rudimentary fires
or cookstoves in one of the world’s poorest countries, but the researchers
point out that there is no local information to reach inhabitants. "Local
information about pollution exposure levels in Mozambique is sorely needed
to ground-truth [our] estimates," said Susan Anenberg of Environmental
Health Analytics and the George Washington University
<http://publichealth.gwu.edu/departments/environmental-and-occupational-health/susan-anenberg>,
US.

Mozambique is thought to be highly vulnerable to the kind of extreme
weather events produced by climate change, and the country also experiences
high rates of morbidity and mortality from household air pollution. In
rural areas, households typically use open fires or rudimentary biomass
stoves, while in urban areas metal charcoal stoves are more common. Fine
particulate matter and other pollution generated by this type of
inefficient burning are known to be highly dangerous, with one previous
study linking household pollution in Mozambique in 2015 to 18,000 premature
deaths.

More efficient options are available: natural- or forced-draft stoves in
rural areas, or modern charcoal stoves for urban environments. In addition
there are gas stoves, which are inherently cleaner than those running on
charcoal.

Anenberg and colleagues wanted to find out how beneficial these
alternatives would be to Mozambicans. Having identified clean cookstoves
that could find success in Mozambique, they estimated air-pollution
exposure levels based on estimates for other parts of Africa. These
estimates went into an atmospheric model and a health and climate-impact
model to make a new estimate of the possible societal benefits, focusing in
particular on deaths arising from stroke, heart disease, lung cancer,
chronic obstructive pulmonary disorder and lower respiratory infections.

The researchers found that if just 10% of rural households in Mozambique
got a natural-draft stove, the country could expect 200 fewer deaths
related to fine particulate matter over three years; if the same households
got forced-draft stoves, there could be 500 fewer deaths. Meanwhile, if 10%
of households in five of Mozambique’s major cities got a gas stove, there
could be 160 fewer premature deaths; modern charcoal stoves would obtain
80% of this benefit.

As for climate change, the researchers found that any of the better stove
scenarios would reduce the contribution to temperature rise from cookstoves
by 4–6% over the next century.

"We found that each type of cleaner cookstove examined led to improvements
in air quality, avoided health impacts from air pollution, and less climate
change-related temperature rise," said Anenberg. "The cleanest stoves were
more health beneficial, but nearly all were cost-effective."

The researchers are now investigating the use of solid fuels for heating.
"Burning solid fuels for heating degrades air quality and contributes to
climate change, particularly in cold areas where the pollution gets
transported to snow and ice covered regions and reduces the reflectivity of
the planet," said Anenberg. "We are trying to determine the extent of solid
fuel heating around the world, which types of fuels are commonly used in
different places, and the impacts this practice has on public health and
the environment."
