Abstract:
Agriculture dominates socio-economic and political life of 130 millions peoples in Bihar - spread to the
vast scratches of river plains in the north to the Chhotanagpur plateau in the south. Low productivity of
major cereal crops resulting into the chronic shortage of food and partial to complete starvation situation
was addressed through large scale adoption of input driven green revolution in 1970s with astounding
success. After two decades or so of adoption of green revolution , truth is out - that only a proportion of
resource rich farmers were benefited; yields are torpid if not declining; diversity of crops are reducing;
insect-pest and disease outbreaks has increased etc. etc.
Given the challenges of ever increasing population and decreasing production base in the state, need for
an alternative research-extension system is crucial for sustainable agriculture production in Bihar.
Agro-ecological intensification based PAR /participatory action research), could be successfully used to
address technological as well as farmers education challenges. This approach brings collaborative inquiryinto the farm problem for sustainable eco- agriculture intensification in order to innovate/adopt/adapt
knowledge-intensive technologies that enhance scientifically sound decision making at the field level.
Often, physical technology e.g. equipment and crop varieties or knowledge change in farmers are
embedded in this approach (like IPM, ICM etc.).
In support of the idea, several examples of this approach, those were funded by FAO / CGIAR will be
provided and lessons learned from these experiences and their impact will be presented here. Followed to
that a short summary and possible action points (including policy implications) will be enlisted in this
regard.

1. Introduction:
1.1 Bio-physio-social condition of Bihar and production trends
The state of Bihar was reorganized on the 15th November, 2000 with 38 districts of erstwhile
undivided Bihar. The state has an area of 94,163 Square Km. and a population of 82.88 millions
according to 2001 census (now 130 millions approximately). The population of the State constitutes 8.07
percent of that of the country with about 3 percent of the area thereof. This adverse land-man ratio is
reflected in the high density of population which is 880 per sq. km. The decadal rate of growth of
population for 1991-2001 has been 28.43 percent which is the highest in the country. The literacy rate in
the state has been 47.53 per cent according to 2001 census as against 38.50 percent in 1991 census 4. More
than 80% of the total population is, directly or indirectly, dependent on agriculture. Almost two third of
the area of the state consists of flood prone alluvial plain of the Kosi Gandak, Sone and other rivers while
the rest one third is constituted by drought prone and Tal- diara areas. The state has achieved self-
sufficiency in food grain productions (see Fig. 1 for recent production trends) but we still need to go
ahead in improving the productivity in order to cater the future needs and to improve per capita income
(Anno.2007). Bihar is among the least developed states of India and has a per capita income of $155 a
year against India's average of $255. A total of 30.6% live below the poverty line against India's average
of 22.15% (Annon., 2007a).

1.2. Green revolution and its impact
The large scale adoptions of Green Revolution technologies in Bihar and elsewhere in India in
70s not only brought with it the bounty of wheat and rice but also probably saved millions from partial
and/or complete starvation. The agricultural sorority in country rightly needs appreciation of its hard work
and dedicated effort to reach out to those farmers who could afford the input-driven model for research
and extension. But with the more grains and better economy for a part of peasantry, green revolution saw
agro-chemicals e.g. fertilizers and pesticides aggressively introduced on a large scale throughout the India
and much of developing world of Asia, and these introductions are not always based on informed needs
of the community. On another side, the package of practice approach, where a suit of agronomic
practices were introduced along with selected varieties of crops, and its massive impact on grain
production astounded almost everyone. Furthermore, the creation of new research stations; agriculture
university in collusion with the agri-industry become the new temple of hope for millions. The HYVs
(high yielding varieties) have definitely, without question raised productivity many fold, however, the
associated input of synthetic fertilizers and insecticides have without question led to a progressive
deterioration of soil fertility, water quality and human and environmental health along with biodiversity
(Whitten and Settle 1998). In addition, these changes in agricultural scene in Bihar and elsewhere in India
brought benefits of specialization those are based on "economies of scale" where mechanization,
specialized know-how and marketing (often through state or central trading corporation or private
corporation e.g. Wheat and Rice procurement by FCI (Food corporation of India) or state trading
corporations) are involved and on exploiting comparative advantages of the local production situation.
The resulting change from a diverse farming to large scale monocultures simplification has a pronounced
effect on field and farm-level diversity and environmental side effects (pollution and loss of
environmental services). Environmental resources and indigenous knowledge have been disrupted and
today, agricultural practices can hardly be defined as sustainable in the state. This situation compelled to
introduce the term/ideas Agro-ecological intensification (Srivastava et al. 1996). Now the question
arises - is it possible to intensify agriculture while enhancing biodiversity? The pursuit of sustainable eco-
agriculture intensification require substantial increases in knowledge-intensive technologies that enhance
scientifically sound decision making at the field level. This can be embedded in physical technology (for
example, equipment and crop varieties) or in humans (for example, integrated pest management, ICM,
SRI, INM etc.), but both are essential. However, the challenges of disseminating information on new
-

technologies or on efficient input use and management are enormous, especially in cases where extension
programmes are ineffective or completely lacking. The earlier paradigm of science being developed at the
international or perhaps national level and then disseminated to farmers using some extension tool as
practiced under T & V system.
A closer examination of T & V system will reveal that they act more as a virtual/real conduit for
external inputs and hardly focus on internal resources such as knowledge, skill and ecological
understanding needed for sustainable agro-ecological intensification. The new paradigm and both-and
demands an active exchange of information among scientists and farmers. Therefore, participatory and
group-based approaches, which focus on learning and empowerment, have been increasingly gaining in
importance (e.g., Pannell 2006, Mishra et al., 2007) for realizing research for sustainable development.
Even in the recent reports progressive decay and ineffectiveness of this extension is highlighted (see
Anderson, 2007 more details).
In this paper, we brief the ecological dimension of agriculture and present some case studies
carried out under auspices of FAO (Food and Agriculture Organization of the United Nations) and by
other agencies like CGIAR (Consultative Group of International Agriculture Research) and Non-
governmental organizations (NGOs) for Integrated Crop and Pest Management (IPM) for rice and
vegetables in some South and SE Asian countries that holds much promises for inching towards
Ecological Agricultural Intensification. We also discuss the relevance of participatory action research
approach for sustainable eco- agricultural intensification in Bihar.

2.1. The ecological dimension of Agriculture
The flow of energy (that involves biological and non-biological agents) drives the carbon,
oxygen, nitrogen and phosphorus cycles. Nutrients are pumped through the system by the action of
photosynthesis and are again made available for recycling by the action of decomposers. Nutrients are
constantly being removed or added; adding more natural substances or synthetic materials than the
ecosystem is able to handle upsets bio-geochemical cycles.
For example, the nitrogen cycle is characterized by fixation of atmospheric nitrogen by nitrogen-
fixing plants, largely legumes (i.e. symbiotic bacteria living in association with leguminous), root-
noduled non-leguminous plants, free-living aerobic bacteria, and blue-green algae. In agricultural
ecosystems, the nodulated legumes of approximately 200 species are the pre-eminent nitrogen fixers. In
non-agricultural systems, some 12 000 species are responsible for nitrogen fixation.
Environmental services and microorganisms: that are vital to agriculture include:
Soil forming and conditioning. A substantial amount of invertebrates (earthworms, millipedes, termites,
mites, nematodes, etc.) play a role in the development of upper soil layers through decomposition of plant
litter, making organic matter more readily available, and creating structural conditions that allow oxygen,
food and water to circulate.
For example, the amount of soil worked over by earthworms is tremendous: 4-36 tons of soil passes
through alimentary tracts of the total earthworm population living on an acre in a year! Termites are the
only larger soil inhabitants that are able to break down the cellulose of wood. Termites play a major role
in tropical soils where there are also soil churners; they move as much as 5 000 tons of soil per acre in
constructing their complex mounds (allowing better rain penetration in soil).
Waste disposal. A succession of micro-organisms occurs in the detritus, involving namely bacteria and
fungi as well as detritus-feeding invertebrates, until organic material is finally reduced to elemental
nutrients. Ecosystems recycle, detoxify and purify themselves, provided that their carrying capacity is not
exceeded by excessive amounts of waste and by the introduction of persistent (synthetic) contaminants.
For example, the nutrient-filtering function of mangroves can be compared to that of oxidation ponds of
conventional wastewater treatment plants.
Pest control. Predation is not just the transfer of energy whereby one organism feeds on another organism
but also complex interactions among predator-prey populations. If a portion of the prey is not available
-

because of environmental discontinuities (a typical case in agriculture), the self-regulating balance will be
dampened. Inter-specific competition keeps more pests in check than we ever could by using pesticides.
Biodiversity. An ecosystem stability (or instability) depends on the results of the competition between
different species for food and space. Predation ameliorates the intensity of competition for space and
increases species diversity. The nature of inter-specific competition and its effects on the species involved
is one of the least known and most controversial areas of ecology.
Beneficial associations. Symbiosis of plant roots with mycorrhizal fungi plays a most important role in
temperate and tropical forests in absorbing nutrients, transferring energy and reducing pathogen
invasions. Parasitism is used in the biological control of insects. Other symbiotic combinations include
animal/fish/tree species (e.g. agro forestry, varietal diversification).
Pollination. 220 000 out of 240 000 species of flowering plants are pollinated by insects.
Carbon sequestration. The capacity of biomass in sequestrating carbon is receiving an increased attention
with the aim of reducing (in the long term) climate change. Where no tillage is practiced, soil contributes
to retaining carbon. As organic agriculture favors minimum tillage (for better retention of water, nutrients,
and biodiversity), the carbon retention potential of soils is becoming an important issue.
Habitat. Although by definition, habitats provide shelter and food, many ecosystems have functions often
discounted. For example, hedgerows around a field provide habitat for over-wintering of beneficial
arthropods.
2.2 Integrated Pest Management: Evolution of a concept
The label Integrated Pest Management has enjoyed different definitions and meanings over the last four
decades and has considerably evolved. FAO, through its Rome based Crop Protection Service (AGPP)
and its Panel of International IPM Expert, played a leadership role in the evolution of the concept
between 1960 and 1980. Within FAO the concept of IPM has evolved from a strictly crop protectionrelated concept to a much more holistic and ecological approach to crop production and protection. And
the evolution of the concept hasnt stopped since. Through the more recent pioneering work of the FAO
IPM Programmes in Asia and a range of international and local development organization partners, IPM
has become synonymous with education and human resource development programs. These programs
often had (and continue to have) farmer training in crop protection and reduction of chemical pesticides
as entry points but have subsequently broadened to include overall crop production. The more recent term
Integrated Production and Pest Management (IPPM), widely used in FAO IPM training programs,
especially on the African continent, more appropriately describes the curriculum content of IPM training
programs. And, equally important, the training curriculum also addresses social issues and community
-

8
development aspects. Thus, the IPM label has evolved from a strictly technical to a much more holistic
approach to crop production, human resource- and rural development. The nature of this new meaning
can be gauged for example by reference to material posted on the website ( www.communityipm.org ) and
the recent 2002 FAO publication titled From Farmer Field Schools to Community IPM: Ten Years of
IPM Training in Asia (FAO, 2002a) {adopted from (Ketelaar and Kumar, 2002)}
2. Bringing science to society through Participatory Action Research Some relevant examplesfrom Asia
Now, lets discuss some of the examples to pursuit the agro-ecological intensification and conservation
agriculture through Participatory Action Research (PAR). We would like to present here 3 case studies
from three different Asian countries, where we believe that sustainable productions were achieved using
IPM/ICM concept.
2.1 Case Study: Reduced Pesticide Applications by IPM Expert Farmers in Eggplant Production in Bangladesh
Brinjal (eggplant) is widely grown in Bangladesh as it is one of the most preferred vegetables
by local consumers. Brinjal receives the maximum amount and frequency of insecticides applications
compared to all other vegetable crops in Bangladesh owing to the susceptibility of the crop to damage
caused by a range of insect pests and diseases (see Table 1; please note that these problems are common
here in Bihar too ). The abusive use of pesticides was confirmed by a baseline survey conducted by the
Department of Agriculture Extension (DoAE) at the beginning of the Phase I of the FAO Regional
vegetable IPM program in 1996-7. This survey showed that farmers apply insecticides up to 80 times per
season with Fruit and Shoot Borer (FSB) ( Leucinodes orbonalis) as the main target. The evident overuse
of pesticides in eggplants called for a major IPM training intervention in order to allow eggplant farmers
to reduce use of pesticides. Two season-long Vegetable IPM Training of Trainers Courses were held inBangladesh throughout the life-time of the FAO Phase I Vegetable IPM Programme. These TOTs were
followed by Farmers Field School (FFSs) and action research programs, with a special focus on allowing
farmers to understand the ecology and management of FSB.

Through weekly Agro-ecosystem Analysis (AESA), FFS-farmers learnt about crop ecology, which
allowed them to make informed decisions on crop management. Life cycles of important pest problems
and their natural enemies were explored through on-site rearing and experimentation. Farmers studied the
important concept of crop compensation through crop compensation studies. These studies allowed
farmers to understand that healthy crops can compensate for FSB damage, especially during the
vegetative growth stage. This new understanding enabled farmers to become confident that not all FSB
damage results into crop loss. IPM farmers then significantly reduced insecticide applications for FSB
early in the crop growth cycle.

Management options that allowed farmers to further reduce the number of insecticide application for Fruit
and Shoot Borer included: Thorough cleaning of seedlings before transplanting to remove eggs and other immature stages; Regular observation of the crop during the vegetative stage and removal of the FSB infested
twigs; FSB management based on weekly crop ecosystem analysis; Improved crop hygiene by sweeping dead leaf and crop debris to remove the pupae of FSB; Keeping the field surface clean and remove crop residues; Removal and sanitation of the FSB infested fruits from the field at the time of harvesting.
As a result of this new IPM knowledge acquired through participation in FFSs, IPM farmers were able to
reduce the number of applications of insecticide from 60-80 sprays per season to 15 sprays per season.
These results are confirmed by more recent impact analysis studies of IPM FFSs training programs
implemented in collaboration with other partner organizations in Bangladesh (see table 2).

Encouraged by these initial successes in pesticide reductions, IPM farmers formed farmers
clubs. In the Jessore region of southern Bangladesh, one of the major objectives of these clubs was to
further enhance the knowledge base of the farmers on wider aspects of eggplant cultivation, including
proper seed bed management and better fertilizer and water management. The IPM Farmer Clubs also
explored and evaluated novel options for FSB management. For example, insect-killing nematodes
(Steinernema carpocapsae) were imported from Thailand for field experimentation purposes by the IPM
Farmer Clubs. IPM farmers learned that these nematodes could kill the FSB larvae by locating the host

deep inside the eggplant branches and fruits. They also learnt that this species of the nematode would not
work if local temperatures would exceed 35 C. Consequently, another more heat-tolerant strain, S.
riobrave, was imported from Australia for experimentation purposes. Some enthusiastic IPM farmers also
learnt that these nematodes could be mass-produced in the homestead. Some of these farmers started
experimenting with rearing the nematodes albeit without much success owing to poor hygiene andcontamination of the culture. The promising and novel option of FSB control with entomopathogenic
nematodes deserves further attention in action research programs that involve IPM farmers.
The FAO Programme assisted other IPM FFSs programs (e.g. implemented by DANIDA-SPPS,
CARE-Bangladesh and local NGO Proshika) in staff training to share the innovative brinjal IPM
experiences. These FFSs programs continue to develop eggplant growers into IPM experts using the FFS-
training approach. Clearly, IPM Expert farmers are able to considerably reduce use of pesticides, increase
yield and make eggplant production more profitable (table 3).
2.2 Case Study: Participatory Action Research on increasing water use efficiency in Rice usingprinciples of System of Rice Intensification (SRI and green mulch in NE Thailand 7
Under a CPWF (Challenge Programme for Water and Food; www.waterandfood.org/ ) small
grant to the Asian Institute of Technology (AIT; www.ait.ac.th ) from CGIARs ( www.cgair.org ) CPWF,
a collaborative enquiry into the water productivity and weed problem issues of the transplanted rice under
the ambient of SRI (System of rice intensification) were carried out with a group of farmers, NGO and
GO personnel in Ban Chaeng, District, At Samart, Roi-Et, Thailand using. PAR. In addition to the action
research, weekly FFSs were conducted for 18 weeks and each week, one or more topics related to water
use in rice were discussed with participating farmers and non-formal education trainees. Two experiments
were carried out during first season in Wet season 2006 and in experiment 1- where the two water
regimes i.e. Just moist (JM) was compared with the farmers practice (flooding), no significant difference
in crop yields were noticed and the JM produced similar rice yield per unit area with less supplementary
irrigation. Similarly in experiment 2 where different legumes were intercropped as cover crop in order to
suppress weed, SRI (see Stoop et al., 2002 for details) and Mung Bean combination was proved to be best
among all other tested bean intercropping, thereby providing high foliage and ground cover as green
mulch to the rice crop grown under SRI system of management. Similar experiments were repeated in the
dry season 2007 with more or less similar trends of reduced water use and increased productivity of rice.

Some of the reports of thisproject and a 5 minute VDO film of this project ( http://www.youtube.com/watch?v=b31LgNMu-hg ) are available on the CornellsUniversity SRI homepage http://ciifad.cornell.edu/sri/countries/thailand/index.html .

The results for both seasons of experiments are shown in fig 1- 4. The results clearly show that higher
water productivity and rice yield obtained under SRI + green mulch (e.g. Mung bean) management
performed better than any existing farmers practice. Yield and water use efficiency advantages of SRI
management compared to farmers practice have been reported repeatedly ( Koma, 2002, Satynarayana et
al., 2006 ) from various countries in South and SE Asia.

Apart from the direct results obtained and their adoption at farmers household and possibly at
their neighborhoods, the skills, developed during season-long FFS training provided opportunity to them
to do adaptive research to test and refine technology and/or management practices under prevailing
condition and added to the ideals of sustainable agriculture in general and water use efficiency in
particular. In present study, bringing SRI practice through FFS approach in a collaborative trial was an
attempt to understand underlying philosophies of linking Science and societies by engaging farmers,
researcher and other stakeholders to scientific research and development.
In this trial, the farmers group learnt ecosystem principles using Agro-ecosystem Analysis
(AESA) - a useful training design, that focuses on field observation and data collection of plant and its
micro-environment, analysis of data and its preparation for display and finally summary and group
presentation, at different growth stage of crop.
The success of such collaboration also encourages for paradigm shift needed for applied research
in small farms of Asia where there is still wide gap between potential farm yield and actual farm yield and
where farmers have greater control over their internal resources to manipulate them for realizing higher
yield (Mishra et al. 2006).
2.3. Integrated Production and Pest Management of Tomato Yellow Leaf Curl Virus and its Vector
Bemisia tabaci a case study form the North Philippines
Tomato yellow leaf curl virus (TYLCV), which is vectored by Bemisia tabaci (whitefly) is a
serious limiting factor for tomato production worldwide. Farmers growing commercial tomato for
Northern Food Company in the Philippines were losing yield and income up to the extent of 80% due to
this problem since past 4-5 years. In response to their request, FAO Vegetable IPM programme began an
intensive training course to train farmers and trainers on this aspect. Followed to that; an action research
was initiated involving the Northern Food Company, tomato farmers, IPM trainers, local and FAO
scientists and others to find ways and means to reduce the virus and vector problem.
Following two tier non-chmical based management strategy were planned:
1. Minimizing virus acquisition in nursery (by introducing low-cost covered nursery)
2. Delaying virus infection in field crop using mulches and mineral oil combination

Clearly the farmers were winner and owners of knowledge in this collaborative process. Their fruit yield
increased, virus and vectors decreased and net income increased. Moreover, the success will depend on
the constant evolution of partnership and collaborative technological innovation in this case.
3. Discussion & Summary
As stated above, the need to grow more crops per unit land with ecological sensitivity (judicious
and prudent use of natural resources etc.) would be most critical aspect of agriculture in coming years.
Changing social order and consumption pattern, new market economical realities, need of farm families
in global-village environment, depleting natural resource base and increasing cost of production would
need a matching and massive change in the existing paradigm of agriculture research and extension in
Bihar and elsewhere in India. These changing environments necessitates change in the farmers
knowledge and require development of partnership of new kind a win-win situation where scientists and
farmers help to preserve natural resource and at the same time feeds the ever growing population.
The significance of collaborative approach that links science and societies is increasingly being
recognized for mitigating these challenges. Action Research programs and associated philosophy
provides good base and opportunity to address these concerns in an integrated manner. Involving
empowered farmers in such collaborative approach could help to explore all aspects of local farm
problems, mindful of local agronomic conditions and taking care of ecosystem for sustainable production
The lessons we can learn from the presented case studies above could have following policy implications:
Farmers education process, which addresses, farmers education and empowerment, is only a first step in
the direction of sustainable research-extension continuum. The ever-increasing demand of location-
specific and need-based technology at the local level and environment-friendly technology at the global
level requires collaborative approach making balance between technological and integrated social
approach.

The experiences presented above entails the viability of such approach for successful intervention at farm
level without compromising local as well as global need. The model could be equally useful for other
crops and commodities as well.
The existing KVKs/ Regional Research institutions/Agriculture universities/college in the
state could well provide interface for research and extension. This would not only insure
better and timely location-specific extension services to the farmers but also act as
complementary technology generation institution within communities.
The human resource development angle in the form of empowered trainers and farmers
could well be another positive outcome of such collaboration. In addition, these empowered
farmers having solid understanding of natural resources environment could well become
partners in formulating farmers friendly and environmental friendly policies.
One of the aspects that help sustain learnt knowledge in farmers is the economic benefit.
Action research as principle actively supports the idea that farmers should well link with
markets, financial institution to produce high quality marketable produce and their products
to derive benefit. On another fronts farmers cooperatives could be formed to produce high
quality agri products for economic sustainability at larger scale. The green payment (a
payment to farmers who adopt sustainable agriculture practices) might be another option to
provide incentive to the farmers engaged in eco-friendly agriculture.
Finally, there is a need of sensitization of research institute and scientists to the value of
participatory action research.
