7. Direct Energy Use in Rice
Production
• Lifting water for irrigation and mechanised tillage are
main activities using energy – diesel and electricity
in case of former and diesel in the second case
• Harvesting is manual – husking is manual,
mechanised and also through small and large rice
mills which uses biomass, electricty and diesel for
boilers and motors
• Long distance transport with motorised means is
common for marketing
• Apart from production, knowledge of energy use in
other cases is limited – yet even here energy use
may be inefficient as is the case in say irrigation

10. Policy Environment
• Spread of irrigation, fertiliser use and
mechanised tillage all facilitated over time by
policies to encourage their use
• Inputs subsidy – fertiliser, diesel and
electricity for irrigation
• Previously diesel prices were not subsidised
but fixed by Government resulting in lower
prices relative to rice due to rising rice prices
and thus encouraging its increasing use - for
electricity the prices were subsidised and
nominally fixed lowering its relative price
over time as next two slides show
• On the other hand, substantial reduction in
public expenditure on research, extension
and marketing in recent past as shown later
14. Climate Change and Bangladesh
• Impact of climate change in
general and on agriculture, role of
agriculture in GHG emission, and
response of Bangladesh to these
issues have to be seen against
these backdrops
15. Losses in Agricultural GDP due to
Climatic Factors Now and in Future
Cost of present climate
variability - 7.4% output/yr
mainly due to lower boro
output. SW coast to be
worst affected.
Future CC lowers output
further by nearly 4%/yr.
GDP loss - US$ 26 bn for
ag & US$ 121 for national
over 2005-50 due present
variability. CC to add more
losses of US$7.7 and 26 bn.
16. Bangladesh Climate Change Strategy
and Action Plan (BCCSAP) 2009
• A consequence of 1/CP13
• BAP
• 4 inviolate principles -
– Food security
– Water security
– Energy security
– Livelihood (incl health) security
• Six pillars, 34 programme areas
• One pillar is low carbon development
• Should be read along with food security
theme and Research and Knowledge
Management themes
17.
18. Research Principles
• From food security view point emphasis on
development and popularisation of various stress-
tolerant varieties
• From low carbon view point, lowering emission in
agriculture
• From livelihood view point, stress on protection of
employment, income and livelihood particularly of
poor, women and those in ecologically fragile areas
• From water security view point, water use must be
absolute minimum without waste
• From energy security view point, minimum energy
needs must be fulfilled
• Each can be done separately; but not a desirable
solution
• Challenge is to satisfy each condition
19. Challenges
• Mitigation in agriculture without adaptation will
threaten food security
• Adaptation without mitigation will raise cost
of production and food will be costlier
• Mitigation & adaptation get intertwined and
must be addressed in this situation
simultaneously
• Both require that water use be economized
through choice of crops, new agronomic
practices, development of drought-tolerant or
escaping varieties, etc so that while energy
use is lowered food production does not fall
20. Immediate Research Needs
• Development of stress tolerant varieties-some
such as shorter duration, drought tolerance,
heat tolerance to lower energy needs and GHG
emission
• Development of CC-smart cropping systems
• Extension and diffusion issues
• Reexamination of subsidy issues to lower
wasteful water, energy use
• Stabilise rainfed rice output so that irrigated rice
dependence for food security lessened &
energy needs and emission lowered
• Lowering irrigation water needs
• Lowering of indirect energy needs
21. Capacity-building needs
• Capacity and technology needs assessment
to be done
• Capacity of National Agricultural research
System to be a priority, particularly for
research with complex and intertwined goals
• Development and transfer of cost-effective
technology
• And of course financing the whole research
and related activities
• Given the slow pace of CC negotiations, a
new or parallel paradigm of global
cooperation needs to be established
