3. Background & Justification
•
Rice (Oryza sativa) is one of the most
important agricultural staples that feed more
than half of the world population.

Globally, agriculture accounts for 50% and 60%
of total anthropogenic CH4 and N2O emissions
respectively (Smith et al., 2007).

within agriculture, intensified rice production
system is one of the major anthropogenic
sources of atmospheric CH4 and N2O (IPCC
2007).

Emissions are predicted to increase by 35–60% up to the year 2030 as a result of the increasing application
of chemical and manure fertilizers (FAO, 2003).

Mitigation of GHGs from agriculture without compromising food and livelihood security of rural poor a
major societal and scientific challenge .

4. Background & Justification

CH4 and N2O production and emission depend on
timing between fertilization and water management and
on the size of the labile N and C pools, which yet to be
investigated.

Agronomic productivity has to be linked with GHG
emission (Yield-scaled GHG emission).

Efficient utilization of differently treated Farm yard manures can be a potential alternative of chemical
fertilizers while their possible alternative GHG emissions need clarification.

Integrated rice farming systems and farmers socio-phychological trait need to be investigated for better
adoption and diffusion of climate smart technologies.

5. Objective and Research Questions
The objective of the current project is to identify and test management practices
which can reduce methane (CH4) and nitrous oxide (N2O) emissions from smallholders
intensified rice farming systems per unit of area as well as per unit of yield and analyze
the farming dimensions and farmers rationale toward adoption and diffusion of
climate smart techniques related to soil nutrients and water management.
 1. What is the impact of timely application of mineral and organic
fertilisers–relative to water table management on N2O and CH4
emissions from smallholders intensified rice farming systems?
 2. What is the yield-scaled nitrous oxide and methane emission
(agronomic assessment of GHG) of intensified rice production systems
and its difference with traditional area based emissions?
 3. How does the quality of organic fertilisers influence methane and
nitrous oxide emissions, their best ways of utilization, and what are the
possible alternate emissions from these organic materials?
 4. What are the livelihood and farming dimensions of integrated rice
farming systems along with smallholder famer’s rationale of adoption
of various “climate smart” techniques related to fertilisation and water
management?

6. Methodology
University of Copenhagen, Wageningen University and International Rice Research Institute
(IRRI) research and laboratory facility will be used for fieldwork and laboratory analysis.
 Field experiment:
Split-plot experiment comprise of water regime (the main plot)and
fertilizer application (the sub-plot) treatments (Liu et al., 2010; Liu et al.,
2012).
CH4 and N2O emission:
Static chamber and gas chromatography techniques (Rochette and
Eriksen-Hamel , 2008).
 Yield-scaled GHG emissions:
According to Mosier et al., (2006) and Linquist et al., (2012)
 GHG emissions and nutrient turnover analysis of Farm Yard
Manure(FYM):
Greenhouse Gas Assessment Incubations (Spokas & Reicosky, 2009) and
real time analysis of FYM
 Farming systems and livelihood impacts:
Farming System and Sustainable livelihood Approach with single visit
recall data collection, interviews and PRA

7. Expected Outcomes
Scientific publications……..
 One to two literature review article
 One to two paper on emissions as studies in fields
 One paper on laboratory experiments
 One paper on Integrated rice farming system and livelihood
