Testing the complex coal–crops–water relationship in Shanxi
In China’s mineral-rich but arid Shanxi province, heavy industry
and small-scale agriculture coexist and must compete for land
and water. Increasingly, regional authorities need to find a
balance between energy security (from coal production) and food
security (from growing crops locally) while ensuring sustainable
use of limited natural resources.
In a pioneering collaboration, IIASA researchers Yuri Ermoliev,
Tatiana Ermolieva, Elena Rovenskaya, and Gui-Ying Cao partnered with
the China University of Mining and Technology in Beijing to develop a
model that attempts to quantify energy–food–water interdependencies
so that any potential adverse effects of mismatched strategic decisions
can be avoided. Taking data from sources such as the Shanxi Statistical
Yearbook 2012 and the China Coal Industrial Association, they tested
four realistic water consumption scenarios on each of 10 scenarios of
coal and agriculture production—a total of 400 scenarios. Variability
(in terms of water availability, soil quality, existing production
facilities and so on) among Shanxi’s 11 prefectures was considered. Rovenskaya stresses that the model does not offer a “best”
solution, but shows a number of alternatives of the coal–crops
mix and demonstrates how constraints on resources affect these.
“Even minor variations in water supply can produce substantially
different results in terms of allocation of coal and crops production and
technologies,” she says. “A relatively small (say,Â
5%) increase in coal
production could lead to a decline in agriculture to the extent that the
province becomes food-insecure and reliant on expensive imports.”
The model is now being extended to enable more robust
long-term solutions, where uncertainties such as weather
fluctuations, demand, international trade, price, and technological
developments can be accounted for. CW

Evidence backs India’s climate stabilization co‑benefits policy
Faced with the challenge of sustaining rapid economic growth while also addressing
climate change effectively, India set out a National Action Plan on Climate Change
(NAPCC) in 2008. This is a series of steps to simultaneously advance the country’s
development and climate change-related objectives of adaptation and mitigation.
IIASA researchers Narasimha D. Rao and David McCollum, together with colleagues from
India’s Centre for Policy Research, reviewed the evidence for the ”co-benefits” between
climate mitigation and development objectives in India from 10 different global integrated
assessment models, including MESSAGE, which projects the greenhouse gas impacts of
energy supply strategies over time.
Their analysis shows that there are strong complementarities across climate mitigation,
reduced air pollution, and greater energy independence. In fact, the more stringent the climate
stabilization objectives are, the greater the gains in these development objectives. This illustrates
that there are synergies, rather than the commonly anticipated trade-offs, across these issues.
“This is the first international study to assess the quantitative evidence behind India’s
co-benefits-motivated approach to climate policy,” says Rao. “Our findings reveal a need for
greater efforts to look at climate policy and development objectives side by side—and not just
energy security but also alleviation of poverty, access to education, and improved healthcare.
Further quantitative analysis of these is needed to better inform climate change policies.” CW
