The decision to convert to organic farming is now highly influenced by governmental financial incentives arising from EU regulations. The exact mix of such incentives depends on the prevailing national government policies and farmers’ access to premium markets for their products. A particular problem for those undertaking a financial assessment of the organic option is the ubiquitous two-year conversion period during which time additional costs are nearly always incurred. Typically, these relate to declining yields associated with the mandatory reduction in agro-chemical inputs, lower livestock density resulting from lower herbage production, investment in conversion-related items such as livestock housing, and an estimated increase in labour requirement over conventional agriculture. However, during this time, organic premium prices are not generally realisable. Hence, most EU governments reflect this lean financial period in their structure of support payments.
State aid to conversion to
organic farming provided under Regn. 2078/92 (EC, 1992) combined with the
growing markets that Regn. 2092/91 (EC, 1991) facilitated by providing a clear
boundary for product labelling and differentiation both provided considerable
financial incentives for farmers to convert (Padel et al, 1999). Consequently, recent waves of 'conversion' have
resulted more from conscious farm management decisions based on a clear
financial assessment of the organic options than mere ideological beliefs.
Hence the terms ‘committed’ and ‘pragmatic’ are now widely employed to discuss
producer motivation within the sector, with the latter term being used to group
those exhibiting a weaker affiliation to the sector, whilst being more likely
both to enter and also to leave when margins are squeezed (Fairweather &
Campbell, 1996). However, under the
Agenda 2000 CAP reform programme, up to 2006, support for agricultural
production will gradually be reduced and, though relatively more support will
be provided for agri-environment measures than previously (MAFF, 2001), the importance of investigating market incentives
for conversion has become paramount. In
addition, the recent Mid-term Review proposals for reform of CAP also seem
likely to both lower support to agriculture as well as de-couple support from
production. To soften the impact of
this, it is proposed that more agri-environmental payments will be made and it
is probable that organic farming will receive further assistance (CEC, 2003).
For these reasons, an investigation, funded by the European Commission, is
currently examining market incentives for the organic sector in five EU
countries – the
Early
development of the European organic sector was predominantly supply driven. In
the early 20th Century organic farming in
In response to evident demand, EC policy in the 1990s began to incorporate mechanisms for organic expansion, which have been variously adopted and implemented in member states. In the early 1990s, two EU Regulations that relate directly to organic farming were introduced:
• EEC 2092/91 covers legally enforceable standards for crop production, labelling and certification (EC, 1991) and was amended in 2000 by EEC 1804/99 which extended regulation to livestock; and
• EEC 2078/92, which introduced support for converting to organic farming under the agri-environment programme (EC, 1992).
They are a reflection of policy-makers belief that organic farming
provides environmental and health benefits and could help in stabilising rural
communities and aiding rural development.
Furthermore, it can be seen as a response to the ‘failure’ of
conventional agriculture (Carruthers et
al, 1997). The above regulations
facilitated more rapid development of the organic sector. In particular, the
1992 agri-environmental regulation allowed member states to introduce support
payments for farmers converting to organic production. Consequently, there was a 44-fold growth in
organically farmed land in the EU, from 100,000 hectares in 1985 to 4.4 million
hectares in 2001, over 3 per cent of agricultural land (Lampkin et al, 1999; SOL, 2002). Table 1
illustrates the relative importance of the organic sector in a range of EC
countries in 2001 and shows that the countries covered in the study reported
here represent a mix of well-developed and emergent organic production sectors. Of the study countries, whilst
Data on the size of the EU organic food market are limited. However, the Soil Association (2002) estimate
that in 2000 it was worth around €9 billion, some 25% of which was accounted
for by Germany alone. According to Hau
& Joaris (1999), the majority of the organic farm area in the EU is down to
grassland and fodder crops, 19% has arable crops and only 8% is used for
horticulture.

Of the study countries,
A comparison of the
targeting of support by product sectors also reveals some insights into support
policy. In
Additional modulation of support also exists. Preferential rates are available to small
farms in
Each country has their own
certification bodies that implement and control the maintenance of organic
standards. The sequence of procedures
for entering into a conversion agreement in order to obtain government subsidy
bears many similarities in the different countries. However, there are some notable variations. In general, to be accepted as a licensee for
organic subsidy, farms register with a certification body and this is dependent
upon the submission of a detailed technical plan for the farm business.
The different methods
available to farmers converting are broadly similar across the case study
countries although exact regulations do differ slightly. In the
A staged conversion process
does have some very strong points in its favour. For example, as Padel & Lampkin (1994)
point out, it does allow a ‘technical’ learning process to take place in the
farmer’s mind as they gradually adjust their procedures, and it also spreads
financial risk. Furthermore, as MacRae
et al (1990) state, the elongated period of change allows both a gradual
‘deintensificaion’ as well as a period of change in attitude towards organic
production by the farmer.
Although some parallels have
been drawn above between support policies, summarised in Table 3, these alone
do not explain differences in the growth rate of organic farming. For example, the

In recent years, ‘case study’ has been used to address the
methodological needs of both policy and organisational research (Smith &
Robbins, 1982). Because the case study
process uses a diversity of approaches to data collection and analysis, it is
better suited to addressing the range of questions that policy and farm
decision makers must answer (Ward, 1997; Coffey et al, 1996) and, within the study, quantitative and qualitative
methods are conducted alongside each other (Hamel et al, 1993). The case study
aims to understand everyday practices through descriptive and explanatory
analyses (Yin, 1994) and, although findings are of unknown generalisability,
the case study is considered to be more flexible to emergent issues and more
sensitive to causal processes than traditional survey techniques (Stake, 1995;
Cassell & Symon, 1994). Furthermore,
case studies have recently gained popularity over full survey and field methods
specifically in the organic research context because they are useful for
comparing organic and conventional production systems (Lee & Fowler, 2002),
are able to capture the diversity and complexity of organic farm management
systems (Hesketh et al, 2002), and
are advantageous when it is important to understand the farm as a ‘human
activity system’ (Padel, 2002).
The case study provides insight into a research question through the
investigation of appropriately selected micro-units, bounded by time (Stake,
1995) but can be employed at different levels.
For these reasons the organic conversion case study was designed such
that 27 individual farm case studies were undertaken in each of the five
participating countries and these constitute a multi-case study for each
country, which together constitute a multi-country case study.
Typically, case study involves on-site data collection (Cassell &
Symon, 1994; Smith & Robbins 1982) of:
·
Objective records: such as field observations; interviews; audio-visual
material; documents and reports; and
·
Subjective descriptions of meaning reached through the interpretation
of the data itself.
In this study, data collection was achieved through the use of
semi-structured interviews of 2–3 hours duration conducted on a one-to-one
basis with the farmer between the winter of 2001 and spring 2002. Before this the interview schedule had been
trialled on-farm to iron out any difficulties in wording and to see if farmers
actually had the necessary information. The interview recording schedule was
sub-divided into three sections as follows:
PART A comprised open and closed questions relating to socio-economic data
about the farm, farmer and farm household, and their perceptions of information
and requirements for, benefits of, and barriers to conversion to organic
farming;
PART B entailed the collection of physical and financial farm data in
order to construct farm budgets; and
PART C consisted of 24 attitudinal statements that identified issues of
known importance to organic farmers derived from previous surveys conducted by
the Bioteknologisk Institut,
Sample
selection
The case study sample is neither random nor probabilistic (Hamel et al, 1993) but can nevertheless
provide a representative picture of systems, rather than their distribution
within the population (Cherryholmes, 1988).
However, for this study, farms were recruited to maximise as far as
possible the diversity of regional agroecology within the country. The exception to this was
Recruitment of farms to the study was based on a sampling frame
constructed according to three broad product sectors - Cereals/Horticulture,
Dairy, and Meat - classified by their current main enterprise as some farms
would change product sector after conversion, and three farm size groups
determined according to the country context.
For example, average farm size in the

which it can be seen that overall the largest farms were found in the
Figure 1. Average case study farm size by product sector
Figure 2 shows the composition of case study farms by product sector in
each of the five study countries.
Differences between countries in recruitment to these product sectors
are partly explained by existing variation in agriculture in those
countries. For example, in

Analysis
Analysis was designed to understand the financial, agricultural and
market related impacts of conversion to organic farming through a combination
of qualitative and quantitative methods employed at different levels of
aggregation according to the following framework and is discussed in more detail

Gross margins, which are the monetary value of output less the variable
costs incurred in producing that output, for organic enterprises in the
Bearing in mind the above issues, a whole farm economic appraisal
method is better able to allow for the ‘interrelated nature’ of organic
enterprises. Thus, in order to obtain
comparable data across countries, such a measure, Family Farm Income (FFI), the
return to the farm family’s own labour, land and capital was calculated. Non-agricultural revenue and costs were
excluded. This measure is used in the
study countries in farm accounting practice and is compatible with material
published by Eurostat and by the Farm Accounting Data Network of the EC. Figure 3 shows how it is derived; it can be
seen that as it does not allow for the imputed cost of unpaid (family) labour,
it over-estimates the true return to the farm family.
FFI was determined for three scenarios––the
current conventional agricultural
situation, the second year of the conversion
period, and for the first year of full organic
status (most often the third year except for permanent crops that need a
three-year conversion period to become certified). Figures for the current scenario were
obtained either from the latest set of farm accounts or, where farm records
were not available, from published standard farm management data. Budgets for the conversion and organic scenarios
were constructed using information provided by the farmer regarding his/her
desired enterprise mix after conversion and their expected market premiums for
organic produce, supplemented where necessary with standard farm management
data, technical expert opinion, and published market data.

Principal Components
Analysis
In Part C of the interview
schedule a seven point Likert scale was used to gauge the level of agreement
with attitudinal statements. These
scores were analysed as mean scores and, in addition, a pilot study of three to
four farmer interviews in each of the five participating countries indicated
the potential for using Principal Components Analysis (PCA) of the data to
identify differences and similarities in attitudes between ‘nationalities’
through the clustering of farmers according to similar attitudes. PCA is a multivariate statistical technique,
which is performed on a set of measured variables to find out which variables
explain most of the variation between the cases. PCA uses similar principles to preference
mapping for consumer research. However,
in this study, the map may be conceptualised as one of interest rather than
preference. The analysis reduces
variables to dimensions, Principal Components (PC), represented as directions
or axes on which the variation between cases is illustrated. The degree of explanation of the variable
accounted for by PCs is expressed as a percentage, thus PC1 provides the biggest contribution to
explaining the difference between cases followed by PC2, PC3, etc. Initially, the PCA did not provide a high
degree of explanation of Likert scores and consequently adjustments were made
to the data in order to increase the clarity and fit of the final map. First, to gain a better understanding of
clusters, the scores for the three questions in each of the eight dimensions
were aggregated. Second, the scale was
reversed for some statements so that all statements in each dimension were
either positive or negative. For
example, in the case of Marketing statements:
the
scale for statement 3 was reversed so that answers gave an indication of
agreement with the positive statement “There are enough processors of
organic food”.
Subsequently, the respondent’s average score for the three statements in
each dimension was used in the analysis.
Kruskal-Wallis test
The Kruskal-Wallis test
(K-W) is a non-parametric, median test that compares average ranks. All 27
cases in each study country were given a rank in relation to each attitudinal
statement. The test then assigned a mean
rank derived from the average of individual farm rankings such that the higher
the mean rank, the greater the group’s level of agreement with the attitudinal
statement, or by referring to individual farm rank scores it becomes apparent
where differences lie. Cases were
analysed in total and grouped according to various socio-demographic variables.
In order to gain a better insight into the context of farm cases, and
to provide a more representative picture of converting farmers, a matrix was
constructed showing a number of farm and farmer characteristics. By grouping cases according to particular
variable indicators, patterns emerge from which it was possible to derive
‘composite’ farm types defined by a mixture of agricultural and
socio-demographic characteristics. These ‘composite’ farm types will form the
starting point for further analysis of the problems facing converting farmers
in a subsequent component of the ‘Conversion’ project.

Figure 5 shows the average
conversion subsidies received per ha of land converted for the second year of
the conversion period. Italian crop
farmers (those with cereals, fodder, olives, vines and nurseries) received the
highest payment per ha converted, €529.
This reflects the high proportion of case study producers growing
permanent crops, which receive the highest conversion subsidy. Portuguese meat farmers received the lowest
conversion subsidy, €48 per ha converted.
However, these were extensive farms with a high proportion of permanent
pasture, which receives a fairly low conversion subsidy.

to give a positive economic perspective on conversion to organic
production. For example, findings from
field studies conducted by CWS Agriculture in the
Comparison of coded
responses to open-ended questions in Part A of the interview schedule revealed
the profile shown below of: farmer motivation to farm organically (benefits);
farmer perception of organic farming (changes required - Figure 6); problems
associated with converting (barriers) and sources of information on organic
agriculture in the study countries:

Meta-analysis, summarised in
Figure 7, of aggregated frequencies across countries provided an overview of
the role of contributory factors in relation to benefits, changes and barriers
to conversion. It showed that:
·
‘The product’ is seen equally as a
benefit and a problem, in terms of marketing the product;
·
Personal issues (lifestyle and beliefs) are
an important motivating factor but are rarely seen to impede successful
conversion;
·
Technical changes appear neutral in terms of
benefits but account for nearly half of the responses concerned with
requirements for converting and potential barriers to the process.
·
Finance is the one dimension that
straddles perceived benefits, changes required and barriers to these; with
about a third of responses in each category related to financial matters.
·
Legislation, and paperwork are perceived equally as a requirement and a problem.

The above comparison of the practice of conversion to organic farming in five EU member states reveals the wide diversity of support systems. Although these are in part necessitated by the diversity of enterprises suitable to different geographical locations, variation can also be assumed to result from different political agendas. Clearly, although the EC requires member states to support conversion, member states prioritise organic farming differently despite the clear proven public good benefits (such as wildlife and environmental enhancement) that result. This is despite the fact that it is emerging that the monetary value of these benefits amounts to a significant proportion of support.
Variation is also seen in farmer attitudes to organic farming. However, there are clearly concerns across countries in the financial benefits of, inputs changes for, and technical barriers to organic farming. Thus, in order to understand current movements in, and out of, organic farming more fully it is necessary to take a closer look at each of the countries here compared and to understand conversion within the national context.
