Rapid Rural Appraisal
(RRA) methodology owes much of its early development to Farming
Systems Research and Extension as promoted by the Consultative Group
on International Agricultural Research Centers (CGIAR). RRA was
developed in response to the disadvantages of more traditional research
methods, including: the time taken to produce results, the high
cost of formal surveys and the low levels of data reliability due
to non-sampling errors. RRA is a bridge between formal surveys and
unstructured research methods such as depth interviews, focus groups
and observation studies. In developing countries, it is sometimes
difficult to apply the standard marketing research techniques employed
elsewhere. There is often a paucity of baseline data, poor facilities
for marketing research (e.g. no sampling frames, relatively low
literacy among many populations of interest and few trained enumerators)
as well as the lack of appreciation of the need for marketing research.
The nature of RRA is such that it holds the promise of overcoming
these and other limitations of marketing research.
RRA Definition
Unfortunately,
there is no generally accepted definition of RRA. RRA is more
commonly described as a systematic but semi-structured activity
out in the field by a multidisciplinary team and is designed to
obtain new information and to formulate new hypotheses about rural
life. A central characteristic of RRA is that its research teams
are multidisciplinary.
Beyond that, the
distinction between RRA and other research methodologies dependents
upon its multidisciplinary approach and the particular combination
of tools that in employs. A core concept of RRA is that research
should be carried out not by individuals, but by a team comprised
of members drawn from a variety of appropriate disciplines. Such
teams are intended to be comprised of some members with relevant
technical backgrounds and others with social science skills, including
marketing research skills. In this way, it is thought that the
varying perspectives of RRA research team members will provide
a more balanced picture. The techniques of RRA include:
- interview and question design
techniques for individual, household and key informant interviews
- methods of cross-checking
information from different sources
- sampling techniques that can
be adapted to a particular objective
- methods of obtaining quantitative
data in a short time frame
- group interview techniques,
including focus-group interviewing
- methods of direct observation
at site level, and
- use of secondary data sources
McCracken et al1.
describe, rather than define, RRA as an approach for conducting
action-oriented research in developing countries.
Ellman2 offers
a good example to compare the "traditional" rural development
research to RRA. He was requested to analyse the achievements
of four types of land settlement schemes in Sri Lanka and to recommend
a policy for future settlement in one million acres of cultivable
land. He was advised, by a statistician, to sample 20% of the
settlements in operation. This meant 80 settlements and two and
a half years of field survey were carried out by two experienced
researchers. Finally, he and his colleague, helped by two assistants,
conducted "full social, economic and attitudinal surveys" with
a sample of 20 settlements. Nine months were needed to collect
the data, and six months to write it up. The result: a two-volume
report of 305 pages. By the time the message (Ellman says "quite
a simple one") was absorbed by those who needed to know it, the
government had changed and suddenly the study had lost much of
its relevance. With the idea of RRA in mind, he is "convinced
that the same message could have been put across more quickly,
cheaply and effectively, with evidence drawn from a smaller, purposively
selected and studied sample and with no significant reduction
in reliability".
Ellman was later
commissioned to carry out another study, and having learnt from
that earlier experience, he identified the minimum amount of data
that was required and was likely to be effectively used for planning
purposes. A team of ten people collected data in six weeks, and
produced a 25-page report with clear recommendations, which were
broadly accepted by the government and the international agency.
The project, concerning integrated rural development, was finally
implemented.
The application
of RRA has been quite wide as regards rural development, for example
in health, nutrition, emergencies and disasters, non-formal education,
agroforestry, natural resource assessment and sociology approaches.
RRA has also been applied in agricultural marketing, although
the marketing orientation of RRA studies has not been very well
defined.
Thus the term rapid
appraisal does not refer to a single technique but to a range
of investigation procedures. Their chief characteristics are that
they take only a short time to complete, tend to be relatively
cheap to carry out and make use of more 'informal' data collection
procedures. The techniques rely primarily on expert observation
coupled with semi-structured interviewing of farmers, local leaders
and officials. In substance the techniques of RRA have much in
common with the social anthropologist's case study approach but
are executed over a period of weeks, or at most months, rather
than extending over several years. To date RRA has mainly been
used in the field of rural development as a short cut method to
be employed at the feasibility stage of project planning.
RRA is also useful
for supporting decisions towards the improvement of agricultural
marketing systems in developing countries. The role that Rapid
Rural Marketing Appraisal (RRMA) can play in this broad sense
of marketing research lies in the identification and prioritisation
of marketing problems, and the evaluation of practical means of
improving marketing functions, to meet the needs for expansion
coupled with higher performance. The first step is to describe
accurately and meaningfully the systems that exist. The next step
is the evaluation of structures and performance, and the major
forces responsible for changing their relationships. In a broader
scope, research must analyse the changing strategic role of marketing
in the development process.
A checklist of
some general and more specific research activities and topics
is suggested in the following, where RRMA seems to be a suitable
approach:
- Description, problems of assessment
and evaluation of marketing systems for design of improvement
projects in production, storage, handling, processing, transportation
and distribution, as well as wholesaling and retailing, analysing
alternatives
- Analysis of marketing feasibility
and social acceptability of performance improvements. Prediction
of effects on conduct and structure, as well as social effects
- Monitoring and evaluation
of marketing activities
- Design and selection of topics
to conduct further or other types of research or trials
- Rural communications design
for interventions in nutrition, technology adoption, health,
housing, standard of living, education, etc.
- Extension techniques assessment
for training and technical assistance
- Design of participatory schemes,
like farmer-managed marketing enterprises supported by a development
or governmental agency
- Rural organisations assessment
- Understanding of resources
use and dependency patterns of local communities
- Design of strategies for reduction
of losses and deterioration in quality, and quality improvement
of agricultural products
- Design of strategies for reduction
in production and marketing activities costs
- Understanding and improvement
of price efficiencies
- Evaluation of proposed changes
in agricultural marketing systems, in terms of objectives
of an efficiency for producers, consumers and intermediaries
- Measurement of performance
of the "macro" level in marketing systems, in terms of development
goals, such as improvement in nutritional status, proportion
of the income spent on food, or increased rural income and
standard of living
- Managerial, technical and
marketing expertise necessity assessment
- Identification and analysis
of existing and potential markets for new food products and
processes
- Understanding of the technical,
social, and economic constraints of traditional farming systems
to define research that will lead to changes of benefit to
the farmer
- Development of projects, products
and processes having an ex-ante market evaluation
- Facilitation of the commercialisation
of socially desirable food products
- Development of pricing, promotion
and distribution techniques, using profitability and economic
criteria
- Analysis of farmers' perception
of farm household risk and uncertainty over practices of production,
storage, and distribution, perception of price incentives
and other stimuli
- Evaluation of systems using
a global perspective: economic requirements of the system,
appropriate social values, the interacting institutions, and
the flow of final results.
Rapid rural appraisal
is a set of techniques that can be applied as a preliminary stage
when embarking on surveys of farmers. The technique essentially
involves an informal, rapid, exploratory study of a specified
geographical area designed to establish an 'understanding' of
local agricultural conditions, problems and characteristics. They
can provide basic information on the feasibility of beginning
a survey project in an area, particularly when one is intending
to survey an area about which little is known.
RRMA is also a
suitable approach in the commercial sense of marketing and not
merely social, that is the research of consumer needs and wants
from the viewpoint which looks at rural people as a target market.
As in the case of social marketing, the application of RRMA will
depend on particular circumstances and research objectives. Some
research topics, both general and more particular, to carry out
RRMA research having rural communities as target markets are suggested
in the following:
- Identification of the needs
of communities in rural areas, and of the future direction
and strategy of food technology research to satisfy those
needs
- Study of the market to discover
a target market or a market segment for which producers might
develop a product
- To test that a project is
"on track", that is according to the wants and needs of the
consumer or the end-user
- Appropriate technology design;
suitability, acceptability, adoption patterns and impact evaluation
of technology changes Identification of intensity and variety
of forms taken by consumers' demands
- Identification of demographic
and psychographic characteristics and constraints on consumer
behaviour that determine and affect the market performance,
e.g. economic status, income, life style, consumption habits
- Knowledge of what consumers
would like to do, and what they are able to do
- Identification of stratification
criteria within rural communities for market segmentation
strategies
- Study of rural people's attitudes
and cultural characteristics towards nutritional improvements,
selection of target groups and development of product to be
supplemented, and selection or design of the delivery system
- Study of individual and organisational
decision-making processes concerning purchasing and consumption
patterns; leadership impact
- Study of consumer needs by
analysing attitudes, motivation, and behaviour, e.g. risk
perception, price perception, brand differentiation and consumer's
knowledge of the quality and range of goods and services
- Development and selection
of product concepts, products testing, experimentation on
developing the prototype product, specification of production
process and products
- Definition of research priorities,
determination of variables to analyse, setting up experimentation
criteria, definition of hypotheses
- Design, evaluation and monitoring
of nutrition programmes
- Development of advertising
strategies: definition, development and testing, and monitoring
and evaluation; audience considerations, valuation of performance
and effectiveness, support for response measurement
- Development of total propositions
for rural requirements: product, packaging, positioning and
advertising
- Design of packaging for rural
conditions: functional considerations, appeal at the wholesaling
and retailer level, packaging screening tests, effect evaluation
- Corporate image research
for firms and institutions working in rural communities.
RRMA can be used
to quickly obtain basic information specifically to aid the generation
of hypotheses and the design of questions for a questionnaire.
In particular information can be gathered relating to:
- farming system characteristics
(e.g. farm sizes and types)
- farmers' decision-making processes
(e.g. how decisions are made concerning the purchase of new
equipment, and the criteria considered important)
- issues of concern to farmers
(e.g. their major farming problems)
- farmers' equipment ownership
(e.g. which type of farmers own which type of equipment, and
where they are located).
With a rapid rural
appraisal the researcher acts like an explorer, making a brief
survey of the horizon before plunging into the depths of the research
from which the wider view is no longer possible. If the researcher
observes keenly at the start, the remainder of the survey process
stands a better chance of success and time will not be wasted.
Without a rapid rural appraisal a researcher may find himself
surveying the wrong area, collecting the wrong type of information,
asking the wrong people, and precious time and funds can be lost
back-tracking.
The appraisal can
produce, at a minimum cost, a rich description of life in the
farming community and an understanding of local agricultural characteristics
that will be invaluable in ensuring that the right areas and people
are surveyed and that appropriate questions are asked.
Differences between
rapid rural appraisal and other approaches
Chambers3 describes
the orientation of RRA as a "fairly-quick and-fairly-clean" appraisal,
and as opposed to the fast and careless studies (he calls them
"quick-and-dirty" studies) and the slow and excessively accurate
approaches ("long-and-dirty").
On the one hand,
the most common form of fast, rough studies - the "quick-and-dirty"
approach - is termed rural development tourism, that is the brief
rural visit by the urban based "expert". Although Chambers says
that it can be cost-effective for the outstanding individual,
it is important to be clear that it can be actually low-cost research,
but of course not cost-effective. This practitioner, as opposed
to the formal academic, wants quick insights and quick results.
"Brief rural visits, snatches of information here and there and
a few observations, anecdotes and impressions are put together
as the basis for time-bound judgements and decisions". Commonly
rural development tourism means highly biased results, especially
concerning anti-poverty biases. In other words, it has large misperceptions
and misinterpretations of the rural reality, and not only due
to lack of time to carry out a deeper research.
Chambers cites
the main biases of rural development tourism as being: spatial
(urban-tarmac-and-roadside biases, that is going only to easily
accessible places), project (neglecting non-project areas), personal
contact (meeting the less poor and more powerful rural people,
men rather than women, users of services rather than non-users,
and so on), dry season (travelling in the post-harvest or post-rainy
season, when it is easier) and politeness-and-protocol bias (lack
of courtesy and convention, lack of adaptation to local conditions,
shortage of time, etc.).
On the other hand,
formal and accurate studies - the "long-and-dirty" ones Chambers
goes on to describe - are longer and more costly solutions preferred
by "well-trained" professionals. They are preferred by the academic
community, interested more in detail, precise observation and
measurement and rigorous and respectable methodology and with
a generally rather unhurried concern for knowledge for its own
sake in the longer term. Formal studies do not generate information
in the early stages, and some, though not all of them, are academically
excellent but finally useless, very likely because of the lack
of opportunity to induce the desired effects or results. Many
are never used: never coded, punched, processed, printed out,
examined, written up, read, understood or known to actually change
action. Moreover, many studies rarely communicate the knowledge
gained; researchers write in a way that makes it unavailable or
unintelligible to bureaucrats in the formal planning system. Chambers3
says "... rural surveys must be one of the most inefficient industries
in the world...; the longer the research takes, the longer and
less usable the report tends to be and the greater the time available
for sweeping the dirt under the carpet". The biggest single blockage
is the failure to "treat statistics as servant rather than master".
Cases to illustrate the fact can be seen all over the world: papers
that, if finally written, are too late to induce the change desired
(for instance, the case already described in Ellman's2 experience).
McCracken et al.1 summarised the main arguments against inefficient
formal (traditional) studies demonstrating that these conventional
methods have a long duration, fixed and formal structure, limited
scope, weak integration, exhaustive depth, "top-down" direction,
low integration with local farmers, high cost and inefficient
use of time and manpower.
As stated earlier,
the point is to determine which information is really relevant,
opportune, understandable and actually useful for the decision
makers: the middle zone (between both extremes, the short-and-inaccurate
and the long-and-excessively-accurate) of greater cost-effectiveness.
The task is obviously not easy and requires experience, knowledge,
and perhaps, as it has been even suggested to define RRA, a lot
of "common sense". It is therefore important to realise that RRA
procedures are more and not less demanding of expertise, when
compared to the "dirty-short" and "dirty-long" approaches. Optimal
ignorance can only be achieved if investigators are both well
informed and sensitive to what they may not know.
Team composition
One of the main
characteristics of RRA is to work with a multidisciplinary team.
The advantages have been already discussed. Chambers3 is emphatic
in pointing out that the argument that it is necessary to have
an integrated and coordinated approach to research cannot be used
as an argument for having only one well-informed and intelligent
person to do it all. Moreover, Beebe4 proposes not using the term
Rapid Appraisal to describe studies done by one person.
The question remaining
is, "which disciplines have to participate?" The point does not
seem to be very critical, since for example Shanner5 et al. think
that the disciplinary speciality of team members is not critical
as long as "several" disciplines are represented. For agricultural
marketing purposes, and of course depending on the objectives
of the research, the best solution seems to be to have at least
a team of two researchers, one with natural-sciences background
(agriculture and related disciplines), and another with social-sciences
background (e.g. economist, sociologist), but both with marketing
knowledge. This background of course is not definitive, yet the
recommendation is still to have at least two researchers. The
particular skills of researchers are discussed in the next chapter.
The recommendation
is to recruit both men and women to be included on the research
team, to overcome the difficulties and take advantage of the situations
associated with researcher gender, as well as to provide possible
different insights.
Another recommendation
is for researchers to have "some" familiarity with aspects of
the systems being investigated. Teams should be composed of a
mix of insiders and outsiders. Insiders or people very familiar
with the area will provide a high-knowledge perspective to the
problem. The outsider's participation may be extremely valuable
to the insiders in identifying possible options and in noting
constraints that might otherwise be overlooked. Outsiders also
can gain insights and knowledge that can guide their research
activities away from the farm. These considerations are in addition
to the points discussed above concerning participation of farmers
themselves.
To carry out research
with real interaction and participation of all members of the
team it is recommended to work with smaller teams rather than
larger teams; a ten-member team is probably too large. For example,
large teams working in the same interview simultaneously can intimidate
rural people.
Opinions differ
on how to structure the time of RRMA, but there is almost universal
agreement on the importance of dividing time between collecting
data and team interactions to make sense out of the collected
data4. Interactions between researchers at the end of each day
and at the end of the field work seem to be essential in determining
the success of the RRMA. Scheduling RRMA time can ensure that
time for group interaction will be adequate and that a variety
of different activities can be covered in a short period of time.
As an initial phase, that is even before deciding on how to structure
the plan, it is necessary to decide on whether to invest in a
preliminary visit by one or two members of the team, expecting
them to explain the forthcoming research, find a place to work
(for the team sessions), arrange vehicles, identify local participants,
request for information, and so on.
The rapid rural
appraisal technique is straight - forward to administer but can
be physically demanding. It cannot be accomplished simply by driving
along a main road looking at fields (although such a method may
be a way to begin). The successful appraisal may require tracking
over fields in high temperatures and/or over difficult terrain.
Researchers must be prepared to collect information in the fields,
market places, or wherever farmers' daily routines take them.
The rapid rural
appraisal requires mental and methodological flexibility. It does
not proceed like the 'formal questionnaire survey' where predetermined
hypotheses are tested. Instead, important questions, issues and
the direction of the study emerge as information is collected.
This is not to say that the informal survey lacks logic, but that
one must be able to accommodate new information and adjust research
plans accordingly.
The principles
of rapid rural appraisals
The following are
the principles of RRA agreed by its practitioners, in spite of
the fact that there are different opinions and criteria concerning
them. These are general principles of theory:
- Optimising trade-offs: relating
the costs of learning to the useful truth of information,
having tradeoffs between quantity, relevance, accuracy and
timeliness of the information acquired, as well as its actual
use. Trade-offs in this sense are not merely mathematical
ratios, but they also entail, in the context of cost-effectiveness,
alertness, observation, imagination and the ability to pursue
serendipity.
- Offsetting biases: through
introspection, it is necessary to identify cognitive biases
and deliberately offset those biases. The recommendations
are: to be relaxed and not rushed; listening not lecturing;
probing instead of passing onto the next topic; being unimposing
instead of imposing; and seeking out the poorer people and
what concerns them.
- Triangulating: using more
than one technique/source of information to cross-check answers,
that is comparing and complementing information from different
sources or gathered in different ways. It also involves having
team - multidisciplinary - members with the ability to approach
the same piece of information or the same question from different
perspectives.
- Learning from and with the
rural people: this means learning directly, on-site, and face-to-face,
gaining from indigenous physical, technical, and social knowledge.
Farmers' perceptions and understanding of resource situations
and problems are important to learn and comprehend because
solutions must be viable and acceptable in the local context,
and because local inhabitants possess extensive knowledge
about their resource setting.
- Learning rapidly and progressively:
this means the process of learning with conscious exploration,
flexible use of methods, opportunism, improvisation, iteration,
and cross-...
Recording rapid
rural appraisal data
Although data collected
through a rapid appraisal is usually for the purposes of one planned
survey, it is imperative that the information is recorded in a
form which will be useful to subsequent surveys in the longer
term. The data should be recorded in such a way that a data-base
can be constructed for use as reference material for all future
surveys.
- The results of appraisal field
research conducted by each team for each area should be fully
written up in a common format. A useful format would be to
construct 'data sheets' on which comments are recorded under
the headings outlined earlier.
- The results of each team's
appraisal maps and data sheets should be combined into master
sheets' to enable subsequent ease of reference and storage.
- Successive appraisal maps
should use common scales, keys, symbols, colours, etc. making
comparison between two areas and two appraisals possible.
The Rapid Rural
Marketing Appraisal report
The entire RRMA
research process and particularly the report should be made "transparent"
to readers of the research, and that concerns reliability and
replicability of findings. It is the responsibility of the researcher
to demonstrate how his or her conclusions were derived from the
data, and in such a way that someone else can follow and, if necessary,
replicate the analysis and achieve the same result or dispute
those conclusions. As a result, the researcher has to "defend"
the validity of his/her research findings and of the whole process,
including the general constraints of the context, and the particular
constraints when collecting and analysing the data. All these
considerations have to be reflected in the research report.
A framework for
the definition of criteria for the characteristics for the validity
of the RRMA report might be:
- Natural History: report of
which avenues were followed and which were rejected. Discussion
of policy context in which the research was conceived, the
original purpose of the study and the initial design; how
these developed, and what factors or findings led to major
shifts in direction, and how the report relates to the policy
context
- Data collected and techniques:
discussion of whether the kind of data collected is that demanded
by the research problem. Evaluation of the data quality. Evaluation
of procedures followed for data collection.
- Analysis: suitability of
analysis (rigorous, systematic, comprehensive and sensitive)
and illumination of policy problem by the data. Evaluation
of data analysis procedures.
- Validity of links between
concepts and indicators: considerations of descriptive validity:
events and indicators being really what they are though to
be; and considerations of conceptual validity: extent to which
the concepts and categories used fit the data.
- Validity of hypotheses or
theories: considerations of theoretical validity; way in which
concepts are handled and the "coherence" of the resulting
theory.
- Theory kept to the limits
imposed by sampling selection: considerations of external
validity. Scope and generalisation of the theory dependent
on the samples used. Replicability considerations.
- External theoretical validity
of the research: relationship of the study to the wider body
of knowledge related. Value placed on the research by those
who commissioned it, and value for all the people concerned
and involved. Project's impact on the definition, development
and understanding of policy. Contribution made to the general
body of knowledge.
Chapter Summary
Rapid Rural Marketing
Appraisal (RRMA) emphasises the essential role that marketing
plays in the rural development process for Third World countries,
and stresses that it is necessary to appreciate the role of "good"
rural marketing research to reduce the risk in rural marketing
decision making. RRMA (as an agricultural marketing research approach)
represents the contextual understanding of agricultural marketing
systems, and the application of ad hoc techniques - as well as
correct adaptation of techniques by offsetting and to some extent
overcoming the difficulties of carrying out research in the rural
environment of developing countries. However, the utilisation
of RRMA has to overcome a good number of misconceptions about
how the ideal marketing research has to be, since decision makers
feel themselves more confident when supporting the decisions in
"cold" figures rather than in actual understanding. Moreover,
they feel it is always required to have formal quantitative surveys,
motivated more by avoiding the negative results than by the positive
expectations.
First of all, RRMA
represents a paradigm to understand rural development and its
marketing implications: understanding development as the result
of:
- the complex interaction of
variables and context, having multiple and changing relationships,
and
- the necessary involvement
and participation of farmers (and rural people in general),
since the very research process, perceives research as a mutual
learning process, including also the research component in
the formulation and monitoring of development projects.
The process implies
not only the generation of projects for the improvement of "pure"
marketing functions. RRMA is indeed a
RRMA understands
marketing systems in all their complexity and final implications.
The interaction and sharing of insights by multidisciplinary researchers
avoids the biased partial views, by analysing the systems (agro-ecosystems)
performance, and understanding that they are the result of the
interaction of social and natural elements. RRMA analyses the
structure of systems and provides a means of predicting the effects
of changes and suggesting improvement actions.
RRMA also considers
research as searching for and analysing data in a fast and cost-effective
way. Moreover, RRMA does not only consider the requirement of
the fair amount and the fair quality of the information to support
marketing decisions, but also gives sufficient openness to accept
and incorporate unexpected but relevant information in an ongoing
process. RRMA links flexible techniques in a coherent form to
collect on-site, cross-check, validate and analyse data according
to those priorities. Equally important, RRMA considers simplicity,
relevance and meaning as basic points in presenting findings and
suggesting action.
RRMA takes into
account the huge cultural diversity of groups of rural population
in developing countries. Secondary data collection, direct observation
and semi-structured interviewing are very useful techniques for
the full on-site understanding and cultural adaptation required
by research, if it is objective. Moreover, the participation of
farmers in the research process, as well as the inclusion of local
researchers and researchers with knowledge about the site and
having multiple disciplines, all contribute towards overcoming
the difficulties in adaptation of the research to the local conditions,
i.e. the adaptation to cultural values and beliefs, language,
perception patterns, productive activities, economies, traditions,
religion, ethical features, politics, and so on.
RRMA offers a reasonable
contribution towards overcoming the difficulties of sampling in
a rural environment. It avoids the biases of "rural-tourism" research,
and tries to study the events on-site, just where they occur or
where the evidence is. As a result, RRMA information, limited
obviously by the scope of the investigation, generates a purposive
sampling frame of key and casual informants and geographical unbiased
transects, without strict statistical representativeness, but
with high natural-objective representativeness. This representativeness
is enhanced by the triangulation procedures, resulting in increased
validity.
RRMA is an emerging
approach, evolving and improving, and therefore it is still limited.
There are types of research than RRMA cannot do, for example that
requiring statistical reliability, strict replicability and quantitatively
precise conclusions. However, it seems to be always useful in
exploring, complementing, supplementing and validating other types
of marketing research - that is to say more formal types - in
rural environments. Its usefulness will depend on the particular
interests of each piece of research, but it is always a viable
alternative.
