Abstract. Reasons for converting to organic farming have been studied in a number of instances. However, the underlying rationale that motivates behaviour is not always made clear. This study aims to provide a detailed picture of farmers’ decision making and illustrate the choice between organic and conventional farm management. Based on 21 interviews with farmers a decision tree highlighting the reasons and constraints involved in the decision of farmers to use, or not to use, organic production techniques was formulated. The accuracy of the decision tree was tested through a written survey of 65 randomly sampled farmers. The decision tree allows to identify decision criteria and examines the decision making process of farmers in choosing their farming method. It also allows to characterize farmer strategies and values, identifying five types of farmers: the ‘committed conventional’, the ‘pragmatic conventional’, the ‘environment-conscious but not organic’, the ‘pragmatic organic’ and the ‘committed organic’. The importance of taking into account heterogeneity in farmers’ attitudes, preferences and goals and their impact on the choice of farming method is emphasized.

INTRODUCTION

2 3

A goal of the Common Agricultural Policy of the European Union (EU) is to integrate

4

environmental considerations in agricultural policy. As a major tool to achieve this, the EU has

5

created the framework for national agri-environmental program in Regulation 2078/92. The

6

national implementations are based on voluntary schemes, inviting individual farmers to

7

contract with government agencies to produce environmental goods in return for compensatory

8

payments. As organic farming is generally seen as an environmentally sound farming practice,

9

Austria is actively seeking to increase the number of organic farms by including an organic

10

farming scheme in the ÖPUL, the Austrian agri-environmental program.

11 12

The ability to reach this policy goal depends on the willingness of farmers to participate in the

13

program and implement changes on their farm (Morris and Potter, 1995; Wilson, 1997; Beedell

14

and Rehman, 2000; McGregor et al., 2001). Various studies have investigated the factors

15

influencing farmers’ motivations for participation in agri-environmental schemes in general,

16

and adoption of organic farming in particular. Most of these studies take a normative approach

17

through surveys, i.e. formal questionnaires including farm and farmer characteristics and

18

allowing farmers to select important barriers to conversion from a predefined list (Schulze Pals,

19

1994; Häfliger and Maurer, 1996; Freyer, 1998; Burton et al., 1999; Drake et al., 1999;

20

Hollenberg et al., 1999; Kirner and Schneeberger, 2000; Rämisch, 2001; Schneeberger and

21

Kirner, 2001; Schneider, 2001; Schneeberger et al., 2002). A strength of this approach is that it

22

allows for the inclusion of a large number of participants. Thus, the data can be analyzed

23

statistically, models built, and the importance of individual barriers quantified. However, These

24

studies offer only limited insight into the structure and the relationship between various barriers

25

to conversion. This can impair a thorough understanding of farmers’ motivation, as usually

26

several interrelated factors are at play, rather than one single barrier being decisive (Kirner,

27

2001). The separate analysis of individual factors can thus be misleading (Wilson, 1997).

28 29

This is where qualitatively oriented studies of farmers’ decision making can offer additional

30

insights and help interpret the findings of normative surveys. This was the goal of studies which

31

have explicitly tried to understand farmers’ choices regarding their farming method by

32

appreciating the role of different motives and convictions as well as their relationship to a 2

33

personal frame of reference. In-depth interviews on reasons for conversion have been reported

34

by several authors (Vogel, 1995; Buck et al., 1997; Lockeretz, 1997 and 1999; Duram, 1999

35

and 2000; Fairweather, 1999; Kaltoft, 1999; Guthmann, 2000; Lund et al., 2002). Although

36

usually encompassing a smaller sample size (usually less than 80 farmers), these type of studies

37

provide a rich picture of the decision-making process and the various factors affecting farmers’

38

choices, both concerning the actors themselves as well as the structural factors in which they

39

are embedded.

40 41

The actor-oriented approach starts with the assumption that different farmers define and

42

operationalize their objectives and farm management practices on the basis of different criteria,

43

interests, experiences and perspectives. However, inevitably, behavior will be linked to

44

structural features of the economy in which any given farmer operates, especially agricultural

45

policy, market configurations and technology design. Indeed, there is a growing recognition of

46

the complex interplay between external and internal factors (Falconer, 2000). Farmers should

47

thus not be seen as the passive recipients of government programs, nor as so routinized that

48

they simply follow laid-down rules or conventions (Long and van der Ploeg, 1994).

49 50

This study, which is essentially exploratory and descriptive, presents a qualitative model

51

depicting the logical structure of the beliefs and preferences that motivate behavior. It should

52

not be understood as either within a methodological-individual framework which

53

conceptualizes farmers as independent decision-makers, or within a structuralist framework that

54

gives primacy to how broader economic and political forces shape farming practices. It aims at

55

an integration of both approaches. Indeed, the farmers’ objective world is molded by how they

56

perceive and interpret structures. Some structural elements may affect one farmer’s decisions,

57

but be viewed as unimportant by another (Long and van der Ploeg, 1994; Duram, 2000).

58

Structural factors should then be understood as mediated by an actors’ perception: they enter

59

the decision process only if perceived to be decisive.

60 61

The aim of the study is to provide a detailed picture of farmers’ decision making and illustrate

62

the choice between organic and conventional farm management. First, the decision tree method,

63

the study area and the data collection process will be introduced. Then, the decision tree and

64

each decision criterion will be presented, illustrated through examples taken from the 3

65

interviews with farmers. In the discussion, the identified farmer types will be characterized and

66

compared with published research results, shedding light on the strategies and rationales of the

67

decision makers. Before drawing conclusions from the study, the strengths and weaknesses of

68

the decision tree method will be discussed.

69 70 71

METHOD

72 73

The decision tree approach

74 75

The approach selected to analyze farmers’ choice between organic and conventional farming is

76

Ethnographic Decision Tree Modeling. The method was developed by Gladwin (1976, 1989a)

77

to model the way people make real-life decisions. Its distinctive features are a reliance on

78

ethnographic fieldwork techniques to elicit decision criteria. When eliciting the criteria, special

79

care is taken to ensure the decision criteria are derived from farmers’ experiences and not the

80

views of the researcher. The criteria are then combined in the form of an inverted tree which is

81

read like a flow-chart, i.e. a set of “if-then” rules. The decision tree reflects the beliefs and

82

motives for selecting the farming method. This descriptive and predictive approach allows to

83

identify the influence of a wide array of factors (McGregor et al., 2001).

84 85

Hierarchical theory of choice assumes that decisions are decomposed so that the various

86

alternatives are compared sequentially using several characteristics or aspects (Gladwin, 1976).

87

The decision criteria can be elicited and formulated as a series of questions which form a

88

decision tree. The decision process is hypothesized to encompass two stages: first there is a pre-

89

attentive process, where a problem is rapidly simplified through eliminating all alternatives that

90

have some aspect that the decision maker does not want. He or she is then left with two or three

91

alternatives that he or she can decide about in a more detailed way in the second stage, the

92

“hard core” phase of the decision process. In this second stage the alternatives are passed

93

through a set of decision criteria (Gladwin, 1976). The position of a criterion in the decision

94

tree does not necessarily reflect its relative importance in the decision (Murray-Prior, 1994).

95

The major methodological concern is to find the specific aspects and constraints decision

96

makers are using. The researcher must determine what information is actually used in making 4

97

decisions, as opposed to information unused in decision making that may nevertheless be given

98

in response to interview questions (Gladwin, 1976).

99 100

To incorporate an explanation of the selection of criteria, Murray-Prior (1994) proposes to use

101

personal construct psychology (Kelly, 1955, quoted in Murray-Prior, 1994). Personal construct

102

psychology likens people to scientists, which attempt to make sense of the world by developing

103

hypotheses, or constructs, about how they anticipate the world to behave and continually test

104

these constructs against what they construe has occurred. They are trying to make sense, discern

105

patterns and establish order in the complexity of the world in which they find themselves. This

106

approach puts the emphasis for the explanation of behavior with the person. Although the

107

environment influences behavior, its effects are determined by the construction system of the

108

individual (Murray-Prior, 1994).

109 110

Decision tree models have been used to study farmers’ decision making in a variety of contexts,

111

e.g. the adoption of agricultural recommendations in Mexico (Galdwin, 1976), the adoption of

112

improved maize varieties in Kenya (Franzel, 1984), the use of chemical and/or organic fertilizer

113

in Malawi (Gladwin, 1989b), the adoption of improved feed crops in Ethiopia (Darnhofer et al.,

114

1997), strategic decisions by wool producers in Australia (Murray-Prior, 1998) or the choice

115

between organic and conventional production in New Zealand (Fairweather, 1999). The method

116

has been found useful for assembling information on farmers’ opinions, perceptions and values

117

in a systematic manner to show the logic behind farmers’ decisions (Franzel, 1984; Murray-

118

Prior and Wright, 1994).

119 120

Some authors (Franzel, 1984; Fairweather, 1999) have used decision tree models as descriptive,

121

not predictive models. However, when used to provide predictions about farmers’ decisions, the

122

trees were accurate, allowing for the conclusion that a hierarchical decision process is at least as

123

plausible as a linear-additive decision process, since most linear-additive econometric models

124

do not give accurate predictions of individual decisions without the use of dummy variables

125

(Murray-Prior and Wright, 1994). Indeed, when compared with other decision-modeling

126

methods, decision trees performed well: Murray-Prior (1994) reports that it allowed identifying

127

the important reasons for particular decisions where other models, e.g. expected utility and

128

regression models, were not successful. When compared to the models generated by a 5

129

classification and regression software (CART), the manually drawn models were more

130

accurate, if more detailed, than the concise trees generated by CART, which also did not

131

necessarily have a ‘logical’ succession of criteria (Darnhofer et al., 1997). Another strength of

132

the decision tree method is that it allows the use of both qualitative and quantitative decision

133

criteria and that the theoretical bias is reduced as no a-priori assumptions are made about which

134

factors should be included in the models (Murray-Prior and Wright 1994).

135 136 137

Structural influences on farmers in the Weinviertel

138 139

The area selected for the study is the Weinviertel, a region in the North-East of Austria (Figure

140

1). The area was selected for its low percentage of organic farms (1%, compared to the national

141

average of 9.8%) and the prevalence of diversified farming, with annual cash-crops, perennial

142

crops (vineyards) and some animal husbandry. Due to the agro-climatic situation, the general

143

yield level of the area is comparatively low, and the expected yield decrease after conversion to

144

organic farming is moderate.

145 146

147 148 149

Figure 1. The study area

150 151

In the study area more than 90% of farms participate in one or several schemes of the Austrian

152

agri-environment program and thus receive compensatory payments. To be eligible for

153

compensatory payments for organic farming, farmers must convert their whole farm, be 6

154

certified and commit themselves to remain organic for at least 5 years. From an economic point

155

of view, the preconditions for conversion to organic farming in the study area are favorable: on

156

the one hand the moderate yield decrease combined with the higher prices for organic produce

157

means that the income from product sales should remain at a level comparable to conventional

158

farming. On the other hand, the income from compensatory payments increase significantly,

159

resulting in a higher farm gross margin (Darnhofer et al., 2003). Overall, the agri-environment

160

program can be seen as supporting conversion through mitigating risk. Still, as the low

161

percentage of organic farms in the study area testifies, the compensatory payments are not

162

sufficient to motivate a large number of farmers to convert .

163 164 165

Data collection

166 167

Past research on motivations for organic farming has focused on organic farmers and the

168

diversity of their motivations. However, to some extend, this leads to a one-sided perspective,

169

as it assumes that those farmers who did not convert simply did not share the reasons put forth

170

by the organic farmers. It does not allow for conventional farmers to have a reasoning that is

171

not defined relative to organic farming, e.g. have strong reasons favoring conventional farming.

172

As Fairweather (1999) shows, including conventional farmers allows to shed light on

173

constraints affecting conventional farmers who have considered organic farming. Assuming

174

that both organic and conventional farmers are diverse rather than a uniform group, and to

175

highlight the reasons that lie behind farmers’ choices of either organic or conventional

176

production, both organic and conventional farmers were included in the study. Organic farmers

177

were asked why they chose to convert, i.e. which factors they considered at the time they made

178

the decision. Given that some of the farmers had converted several years ago, it cannot be

179

entirely excluded that their experiences as organic farmers influence the narrative of their

180

conversion decision. However, during the interviews careful attention was made to focus on the

181

decision criteria at the time of conversion. Conventional farmers were asked whether they had

182

ever considered converting to organic farming and which factors influenced their decision, i.e.

183

what aspects of conventional farming were important to them, and/or, if they had considered

184

converting, which factors they perceived as obstacles.

185 7

186

The data were collected early 2001 in a two-stage process. First, 21 on-farm interviews with a

187

non-random sample of farmers were made to elicit decision criteria, 9 with organic and 12 with

188

conventional farmers. These farmers were suggested by the local office of the Chamber of

189

Agriculture and selected for diversity, i.e. to include farms with various enterprises and size, as

190

well as, for the organic farms, time since conversion. This procedure was felt to be the most

191

efficient way to achieve a large variety of interview partners despite the possibility of a

192

selection bias, i.e. that only farmers on good terms, or those sharing certain views with the

193

Chamber of Agriculture, might be included. However, the interviews revealed a wide variety of

194

motivations and no significant decision factor advanced in the literature was found missing.

195

Also, as the decision tree would be tested using a random sample, a high error rate would reveal

196

a bias in the sample used to build the tree.

197 198

The on-farm interviews provided detailed background information as well as the factors that

199

were taken into consideration when the decision to convert to organic farming was made, or

200

those that explain why a farmer prefers to remain conventional. Farmers’ reasons for and

201

constraints against action were then formalized as decision criteria that are posed as discrete

202

questions, which can be either accepted or rejected. These criteria are then combined to a

203

decision tree. The different decision criteria for each farmer in the model-building sample are

204

combined in a logical fashion while preserving the ethnographic validity of each individual

205

decision model (Gladwin, 1989). The tree must allow each farmer to move downwards through

206

a series of criteria to an end-point which reflects the farmer’s choice. In addition, the tree must

207

combine criteria for all farmers in a logical way. The tree tells why a particular outcome is

208

achieved for each farmer because the outcome is preceded by a subset of criteria relevant to

209

particular farmers (Fairweather, 1999).

210 211

As recommended by Gladwin (1989a) this decision tree was tested for its predictive accuracy

212

through a mail survey of a second, random, farmer sample, using a structured questionnaire

213

where each decision criterion was represented through one question. These questions were no

214

longer open-ended but designed to elicit informant’s yes/no responses. The wording in the

215

questionnaire is adhered to in the decision tree, as closely as translation allows. The

216

questionnaire was mailed to a random sample of 70 farmers, 35 conventional and 35 organic.

217

The sample was drawn randomly from the official list of farmers receiving direct payments 8

218

within the Common Agricultural Policy of the EU. Farmers were classified as organic if they

219

participate in the agri-environmental program and receive compensatory payments for organic

220

farming. To ensure a high return rate and comply with personal data protection requirements,

221

the list of randomly sampled farmer’s names was sent to the local Chamber of Agriculture who

222

contacted the farmers and inquired whether the farmer was willing to participate in the study. If

223

a farmer was not willing, the next farmer of the list was contacted. Although possible, a bias

224

due to the involvement of the Chamber of Agriculture is expected to be very small, since the

225

Chamber was provided with a predetermined list of farmers. Of the 70 mailed questionnaires,

226

65 were returned, 33 from organic and 32 from conventional farms.

227 228 229

RESULTS

230 231

Description of decision criteria

232 233

The structure of the decision tree (see Figure 2) shows that organic farming must be considered

234

a ‘feasible’ production method before a farmer will consider organic farming in any detail. Just

235

as some farmers oppose organic farming on fundamental grounds, i.e. exclude organic farming

236

preattentively, others opt for organic farming based on a deeply held conviction. Farmers who

237

neither feel strongly that conventional farming is the ‘only way’, nor hold deep convictions

238

regarding organic farming go on to consider the potential impact that a conversion would have

239

for their farm organization, the second stage of the decision process. It includes the perceived

240

constraints on action and pertain to the requirements of sugar beet production, vineyards and

241

animal husbandry under organic farming. If these farm activities are not present or if the

242

requirements are not perceived as a constraint, then reasons for producing organically are

243

considered. Farmers for whom those reasons are not attractive remain conventional. In Figure 2

244

the number in parentheses next to each of the possible ‘yes’ or ‘no’ answers indicate the

245

number of farmers from the test sample selecting this particular answer. To reflect arguments

246

what were mentioned together by farmers as well as to allow for a more concise tree, several

247

criteria in the figure are a combination of two sub-criteria. These were stated as individual

248

questions in the questionnaire, and discussed separately below, but combined in the decision

249

tree as a negative answer to either question leads to the same next question or end-point. 9

250 251 252 253

Figure 2. Decision tree depicting the criteria considered in the choice between organic and

254

conventional farm management in the Weinviertel

255 256 257

Criterion 1 combines two questions assessing two fundamental beliefs of the farmers regarding

258

organic farming: is it more environmentally friendly than conventional farming and/or are

259

organic foods healthier? Although these two aspects are very different, only those respondents

260

who answer either or both question with a ‘yes’ move on to the second criterion. Those who

261

cannot agree with either statement are classified as conventional. These farmers do not perceive

262

their methods as being harmful to the environment, since most participate in one of the schemes

263

of the agri-environmental program (e.g. “reduction of yield increasing farm inputs”) and,

264

therefore, use significantly less nitrogen fertilizer than ten years ago. They feel that the

265

environmental issues are exaggerated by the media and that they are not linked to their farming

266

practices. Indeed, inputs (fertilizer, biocides) are expensive and as good managers they only use

267

the minimum required amount and apply it only when needed. These conventional farmers also

268

do not perceive organic farming as being environmentally friendly. For example they note that

269

since some organic pesticides are more efficient than conventional products, they cannot be

270

more environmentally benign. Also, the fields of most organic farms are surrounded by those of

271

conventional farms, and therefore organic produce is bound to contain synthetic pesticides from

272

their neighbor’s spray drift. Lastly, they point out that the repeated application of copper-

273

containing preparations in the vineyards leads to the accumulation of trace metals in the soil.

274

These farmers not only see organic farming as falling short of its environmental claim, they also

275

doubt the statements made regarding the ‘healthiness’ of organic produce: as synthetic

276

pesticides are not used, plants have to ‘defend’ themselves and this may result in increased

277

concentrations of secondary plant metabolites. Also, since synthetic fungicides are not used,

278

there is a higher level of fungi incidence and therefore higher mycotoxin contamination levels

279

in grain. Some point out that the quality of processed organic food is not higher than that of

280

conventional food, since it contains just as many additives.

281 10

282

The second criterion of the decision tree addresses the perceived feasibility of organic farming,

283

i.e. does it ‘work’? It has two aspects, depending on whether a farmer defines ‘successful

284

cropping’ through the yield level (i.e. quantity of produce) or profit per hectare. The first aspect

285

is related to criterion 1, and identifies farmers to whom high yields are important. They are

286

convinced that this is only possible through using synthetic fertilizers, pesticides and fungicides

287

as needed. Regarding wheat quality, they point out that without nitrogen fertilizers a high

288

protein content cannot be achieved, as the nitrogen release from organic (green) manures cannot

289

be synchronized with plant requirement. They are also convinced that under the climatic

290

conditions in the Weinviertel, it is not possible to achieve high quality produce without

291

fungicides. The second aspect of this criterion is the profitability of organic farming: if yields

292

are lower, prices must be significantly higher. However, many farmers do not think that the

293

majority of consumers are willing to pay a higher price for organic produce. They see the

294

organic market as a niche and expect the supply to rise faster than the demand, leading to a drop

295

in prices, thus affecting profit per hectare.

296 297

These two elimination criteria identify 20 conventional farmers who do not think that organic

298

farming is an environmentally desirable and/or technically or economically viable alternative

299

and, therefore, do not deem it worth of serious consideration. Most of these farmers do not seek

300

further information on organic farming as they do not feel that it is relevant to their farm. For

301

the remaining 45 farmers, who did not answer any of these questions with a ‘yes’, organic

302

farming is at least an option they are willing to contemplate as they consider it a viable farming

303

method. The next criteria seeks to identify those farmers who have a strong environmental

304

motivation for their choice of farming method.

305 306

Criterion 3 seeks to identify farmers to whom net income maximization is not a primary goal

307

and to whom other values such as the environmental impact of their production method, health,

308

ethical and/or lifestyle issues are key. Their willingness to risk some income to farm in an

309

environmentally friendly way does not imply that, in the long run, they expect a lower net

310

income as organic farmers. These 31 farmers are willing to adapt their farm organization and

311

select new farm enterprises so that the requirements of organic farming will match their

312

resources.

313 11

314

Of the farmers who are willing to forgo some of their income, eight were faced with a perceived

315

constraint preventing them from participating in the organic farming scheme of the agri-

316

environmental program up to now. Criterion 4 addresses the issue of higher labor requirements

317

in organic farming. Indeed, organic farming is generally perceived to be more labor-intensive

318

than conventional farming. This is an issue for a number of interviewed farmers, who pointed

319

out that modern living standards are defined by leisure time and that those who are not engaged

320

in farming have fewer working hours and have the possibility to take extended vacations. A

321

farmer also pointed out that although he and his wife do not mind, his son finds it difficult to

322

work late, particularly in summer when his friends roam around with their motorcycles after 5

323

pm. The farmers also noted that due to the limited supply of family labor they might have to

324

hire labor, which many are not willing to do. This is partly linked to the fact that few Austrians

325

are willing to perform manual farm work and that hiring foreign nationals (primarily Czechs as

326

the border is quite close) involves burdensome and often expensive administrative

327

requirements. Also, language barriers can result in miscommunications.

328 329

The 14 farmers who are not willing to risk foregoing some of their net income for the benefit of

330

environmentally friendly farming go on to assess the technical requirements and organizational

331

changes a conversion to organic farming would imply (criteria 5 to 13). Since environmental,

332

health and/or lifestyle considerations are less important for most of the farmers on this branch

333

of the decision tree, the current prices of organic products and the level of compensatory

334

payments were triggers for organic farming to be perceived as an option worth considering.

335

However, as these farmers do not have a strong emotional motive for organic farming, they

336

tend not to be willing to change the organization of their whole farm to fulfill organic farming

337

requirements.

338 339

Criterion 5 investigates the importance of sugar beet for the income from farming. For

340

conventional farms in the area sugar beet is one of the most profitable crop. Criterion 6

341

addresses the fact that in organic farming, where herbicides cannot be applied, weeding must be

342

done manually and requires substantial labor for extended periods of time. Also, since there is

343

no market for organic sugar beet in Austria, no price premium can be expected. The high labor

344

requirement thus results in a lower return per hour of labor compared to conventional

345

production methods. Farmers with a sugar beet quota who are interested in converting to 12

346

organic farming and for whom the production of sugar beet is not attractive could consider

347

selling their sugar beet quota (criterion 7), which is possible since 1998. Although none of the

348

farmers included in the test sample indicated that sugar beet is a major constraint, this path was

349

left in the decision tree as it was mentioned in the interviews.

350 351

Criterion 8 selects farmers who have vineyards and for whom they are an important source of

352

income. For farmers who have only small vineyards, these issues do not carry much weight in

353

their choice of farming method. The primary arguments against organic management of

354

vineyards is that the production risk is too high and/or the fear that the quality requirements

355

cannot be met using organic methods (criterion 9). The risk involved in organic vineyard

356

cultivation is mainly the fear of a year of very high pest incidence or unfavorable climatic

357

conditions leading to high fungi incidence, which could lead to a total crop failure. Since

358

organic methods mainly aim at preventive measures, the effectiveness of organic methods are

359

limited once there is a high pest incidence. Also, one interviewee thinks that many fining agents

360

used in the wine making process are prohibited in organic processing and, therefore, may

361

endanger continuous wine quality. She expects a high marketing risk if she were to convert. On

362

the one hand she does not feel that her customers are willing to pay a price premium for organic

363

wine. On the other hand, she was concerned that if she had a bad year (regarding quantity or

364

quality), she might lose customers, who would be difficult to regain the following year.

365

However, for farmers who have both field crops and vineyards and who are interested to

366

convert only their fields to organic production, can, under narrowly defined conditions, split

367

their farm in a crop farm which they convert to organic farming and a vineyard farm which

368

remains conventional (criterion 10).

369 370

Criterion 11 addresses issues related to animal husbandry. Although 26% of farmers in the

371

study region are engaged in animal husbandry, most keep only a few animals to cover their

372

family needs. If animal husbandry is an important source of income, two issues are crucial: feed

373

supply and animal housing. Producing certain feed crops under organic management can be

374

perceived as a problem (criterion 12). For instance, one farmer raises steers and knows from

375

another farmer in the village that weeds cause a serious problem in organic maize production,

376

as it is a fairly dry area. He does not perceive conversion to organic farming as an option, as he

377

would have to purchase organic feeds, which are expensive. As far as animal housing (criterion 13

378

13) is concerned, strict regulations have to be implemented, requiring significantly more space

379

per animal in the barn as well as access to outdoor areas. It is therefore often necessary to build

380

a new barn or adapt the current one resulting in a major long-term investment. The fact that

381

none of the farmers included in the test sample stated that this was a decision criterion to them

382

might be due to the subordinate role of animal husbandry in the region.

383 384

The nine farmers (6 organic and 3 conventional) not identifying obstacles in their farm structure

385

and organization, go on to consider the contractual aspect of participating in the agri-

386

environmental program. Criterion 14 addresses the regulations imposed by the organic farming

387

scheme of the agri-environmental program as well as those by the organic farmer associations.

388

Criticism is mainly voiced regarding the sometimes vague definitions, leaving room for

389

interpretation by the controllers and thereby making the farmer dependent on his/her

390

subjectivity. Also, these farmers feel uneasy at the prospect of signing a five-year contract

391

within the agri-environmental program, aware that the government may change the regulations

392

within the contract duration. These on-going updates and changes result in ever more complex

393

regulations, making it increasingly difficult for a farmer to keep up and be certain to comply

394

with all rules and regulations. This is not made easier by fact that farmers perceive the

395

information provided as insufficient and do not feel adequately informed of upcoming changes.

396 397

Finally, the seven farmers who do not perceive either the technical or farm structural aspects

398

nor the regulations as obstacles to conversion, assess whether the perceived ‘side-effects’ of

399

converting to organic farming are attractive to them. Criterion 15 differentiates between those

400

farmers who are looking for the challenge to do things ‘differently’, i.e. who are not interested

401

in following the conventional path of specialization and increasing mechanization. For example

402

one of the interviewed farmers worked part-time when he took over the farm, minimized on-

403

farm labor requirements and focused on small grains. This management concept was simple,

404

but it was not rewarding. He decided to become a full-time farmer and to try his ideas for new

405

crops and activities. For him, the compensatory payments guarantee some income, offering the

406

room for experimentation and time to learn from experiences. This farmer also got engaged in

407

processing and direct marketing, enjoying the contact with customers and the feedback on his

408

products. This search for a ‘different’ way also includes farmers who perceive organic farming

14

409

as a challenging and promising option for financial reasons, and who want to take advantage of

410

the current high level of demand and the attractive price premiums.

411 412 413

Accuracy of the model

414 415

Since one of the aims of a decision model is to predict farmers’ choices, the proper test of the

416

model is its ability to explain the decision of a random sample of decision makers. The

417

accuracy of the decision tree can thus be calculated as the ratio of correctly predicted choices

418

divided by the total number of farmers included in the test sample (Gladwin, 1976). A

419

misclassification occurs if the decision tree predicts that farmers reaching a specific end-point

420

would be organic, whereas a particular farmer following this path is actually conventional or

421

vice-versa (the number of farmer with a farming method that is different from the one expected

422

at each end point, is listed separately in Figure 2). Of the 65 farmers included in the decision

423

tree, 11 were misclassified, leading to an accuracy of 83%. This is within the range of the

424

models presented by Gladwin (1976) and those reviewed by McGregor et al. (2001), who report

425

that models developed using this approach have predicted better than 80% of decisions by

426

farmers not included in the sample used to develop the model.

427 428

In the model, the main criterion leading to misclassifications is criterion 4, addressing the issue

429

of labor requirements. Indeed, criterion 4 does not lead to a clean split between organic and

430

conventional farmers: out of 31 farmers following this path, two conventional farmers are

431

predicted to be organic, and six organic farmers are predicted to be conventional. If criterion 4

432

would be deleted, and all 31 respondents answering ‘yes’ to criterion 3 would be labeled

433

organic, the model would improve its accuracy from 83% to 92%. The mislabeling of six

434

organic farmers caused by criterion 4 is due to the fact that these farmers stated that the labor

435

requirements in organic farming are higher than the available family labor and that they are not

436

willing to hire non-family labor. Yet, despite this perceived labor bottleneck, they are still

437

organic. McGregor et al. (2001) suggest that when a decision is inconsistent with the answer to

438

a criteria, it indicates that the criterion reflects a belief rather than a decision rule. The

439

ambivalence regarding labor availability may be due to short-term issues which will be solved

440

through reorganization of the farm. It may also reflect how different people on the farm 15

441

perceive and value the type of labor they carry out and their specific control over the labor

442

process and benefits derived (Jansen, 2000). As Franzel et al. (2001) point out, the acceptability

443

of a technology depends on its feasibility from the farmers’ point of view, and its value to them.

444

Therefore, apparent constraints such as labor difficulties that farmers mention when attaching a

445

low value to an activity, may disappear when the farmers’ perception of the value increases. It

446

then seems that subjectivity plays an important role when labor is cited as an key issue in

447

relation to organic farming. This is also reflected in the inconclusive reports in the literature

448

regarding the generalized character of higher labor requirements in organic farming, and the

449

lack of understanding of the precise factors that cause an increase in labor demand (Jansen,

450

2000).

451 452 453

DISCUSSION

454 455

Farmer types and their rationale

456 457

The decision tree allows insights into the values and beliefs underlying farmers’ choices. Based

458

on these, farmer types were identified, each with a distinctive rationale motivating their

459

behavior. The labels used to characterize the farmer types partly reflect those proposed by

460

Fairweather (1999), who identified two types of organic farmers, the “committed” and the

461

“pragmatic” as well as three types of conventional farmers. These are labeled according to their

462

position towards organic farming: the “hopeful organic” and “frustrated organic” who are

463

interested in a conversion, and those who are not, and thus “do not grow organic”. However, if

464

the “pragmatic” and “committed” labels were taken from Fairweather (1999), the symmetry in

465

the labeling of organic and conventional farmers reflects the results of Schoon and Te

466

Grothenhuis (2000), who differentiate between “idealistically motivated farmers”, i.e.

467

conventional and “ecological” farmers whose choice of farming practice is rooted in strong

468

convictions and ideals; and “pragmatically motivated farmers”, which can switch more or less

469

easily between conventional and “ecological” farming. This symmetry is also identified in the

470

current study, which shows that of the 32 conventional farmers, over 60% reject organic

471

farming for fundamental reasons without assessing the implication of conversion for their own

472

farm while of the 33 organic farmers, nearly 85% are organic by conviction. 16

473 474

The decision tree (Figure 2) identifies five types of farmers, three being conventional and two

475

organic: the ‘committed conventional’ (20 farmers), the ‘pragmatic conventional’ (8 farmers),

476

the ‘environment-conscious but not organic’ (2 farmers), the ‘pragmatic organic’ (3 farmers)

477

and the ‘committed organic’ (21 farmers). In Figure 2, farmers whose farming method is not the

478

one predicted by the decision tree are not included in the total number of farmers for each

479

farmer type. For example only two farmers are labeled ‘environment-conscious but not organic’

480

as of the eight farmers reaching this end-point, two are correctly predicted conventional farmers

481

whereas six are actually organic farmers.

482 483

‘Committed conventional’ farmers are characterized by not even considering a conversion to

484

organic farming. They do not view organic farming as more environmentally friendly than

485

conventional production methods, they do not believe the health claim made of organic foods,

486

nor do they perceive that organic production is technically and/or economically feasible. Their

487

arguments echo those found in publications discussing potential shortcomings of organic

488

farming (Kirchmann and Thorvaldsson, 2000; Edwards-Jones and Howells, 2001; Rigby and

489

Cáceres, 2001; Trewavas, 2001). Their attitudes and values reflect several elements of the

490

conventional paradigm as described by Beus and Dunlap (1990). They structure their farm

491

along the lines designed by science and agribusiness and articulate clearly that this conventional

492

approach to agriculture is the only sensible one. This reflects the characterization of the

493

“vanguards” or “optimal farmers”, who are guided by the modernization paradigm in its focus

494

on external inputs, new technology, scale-increase and specialization (Long and van der Ploeg,

495

1994). These “optimal” farmers focus on minimizing production costs and maximizing output

496

per hectare while producing primarily for bulk-markets (Roep and de Bruin, 1994).

497 498

‘Pragmatic conventional’ farmers do not have a fundamental stance opposing organic

499

farming. However, they point out that a conversion can entail a substantial amount of risk: they

500

focus on the technical challenges of conversion, the uncertainty of price and market

501

development and the regulatory constraints. Overall, they perceive a conversion as entailing

502

profound changes in their farm organization and are not eager to implement them unless

503

expecting a tangible benefit. They are likely to be more open to conversion once technological

504

uncertainties have been cleared by the experiences of organic farmers in the area, and once the 17

505

market for organic products are established. However, if a lower economic risk of conversion

506

can help to increase the number of farmers who consider organic farming, it is unlikely that by

507

itself it will be a sufficient motive for conversion. Indeed, reports in the literature (Burton et al.,

508

1999; Lohr and Salomonsson, 2000; Pietola and Lansink, 2001), as well as the decision model

509

presented here, show that for most farmers perceived economic viability may be a necessary

510

condition for conversion, but it is not a sufficient one. In their search for a way out of the

511

“squeeze on agriculture” resulting from the modernization paradigm (van der Ploeg et al.,

512

2000), the ‘pragmatic conventional’ farmers will include organic farming as well as options that

513

do not require a conversion (e.g. farm diversification, off-farm income). However, as they do

514

not rule out organic farming, they can be seen as a pool of potential converters.

515 516

‘Environment-conscious but not organic’ farmers are committed to environmentally friendly

517

farming practices, but are currently not receiving payments within the organic farming scheme

518

of the agri-environmental program. This farmer type can include a variety of subtypes, e.g.

519

conventional environmentally friendly or self-declared organic. As they do not subject

520

themselves organic regulations and controls, these farmers keep a measure of flexibility e.g. to

521

manage only some farm enterprises following organic guidelines and/or to use some synthetic

522

inputs on crops in case of need, thereby reducing their risk. This farmer type also includes

523

farmers who have converted their whole farm, but are reluctant to sign the agri-environmental

524

contract binding them for five years. Others might follow the organic standards very closely,

525

but be wary of the bureaucracy and paperwork involved in certification and/or participation in

526

the agri-environmental program. This has been reported by Burton et al. (1999) who describe

527

self-declared organic producers who are not registered, who tend to have strong views

528

regarding the perceived disadvantages of certification and/or who want to remain independent

529

of the regulations. To some extend, the cost of participating in the organic aid scheme might

530

also play a role. As Falconer (2000) points out transaction costs (e.g. certification, record-

531

keeping) can cost farmers up to 10% of typical compensation payments for organic farming.

532

Thus, for some environmentally committed farmers, the administrative aspects discourage them

533

from participation in the agri-environmental program. Marketing aspects also play a role, as

534

some interviewed farmers feel that alternative farming methods ensure a product of high

535

quality. However, since they have an established clientele willing to pay a premium without

18

536

requiring the organic label, they do not see the need to convert to organic farming, as they have

537

forged a relation based on trust and product quality.

538 539

To ‘pragmatic organic’ farmers, health, ethical or sustainability aspects are not dominant

540

motivations for conversion. This type of farmer tends to perceive organic farming as offering a

541

good prospect for securing their income. Especially the compensatory payments within the agri-

542

environment program are then an important incentive for conversion. Of the sample included in

543

the study, most of the farmers in this type have converted since 1995, the year where the agri-

544

environmental program was introduced in Austria. The decision tree thus supports evidence that

545

many of the farmers who have converted since the late 1990s may have been driven more by

546

financial motives rather than by non-economic considerations (Jansen, 2000; Padel, 2001;

547

Rigby et al., 2001). However, even if financial motives play an important role, it is not

548

necessarily related to an income-maximization attitude (Padel, 2001). Mostly, this type of

549

farmer perceives the compensatory payment as enabling a process of “learning by doing”, of

550

experimenting with new ventures, supporting him/her in the search for a more satisfying work.

551

He/she appreciates the skill requirements, the craftsmanship and the diversity of tasks. This

552

echoes several reports on how individual realization of professional and personal potentials

553

have gained importance as a motivation for conversion (Noe, 1999; Hall and Mogyorody, 2001;

554

Michelsen, 2001). It also supports Morgan and Murdoch (2000) in their assessment of organic

555

farming as offering more autonomy and control to farmers, who can once again become

556

“knowing agents”, as organic farming revalues local knowledge and local identities.

557 558

This type of farmer follows a strategy that is close to the one of “farming economically”

559

described by van der Ploeg (2000), i.e. a strategy based on low level of dependency on external

560

inputs, flexible and multiple use of resources, local innovativeness, and low expenses. They are

561

primarily looking for an alternative to the conventional farming system, either because they

562

resent agri-business or because they do not believe in the modernization paradigm and thus seek

563

a way out of the “treadmill” (Ward, 1993). In this strategy, they can be understood as

564

‘pragmatic conventional’ farmers who have selected the organic option.

565 566

The ‘committed organic’ farmers are deeply rooted in the founding philosophy of organic

567

farming, which is based on the rejection of synthetic fertilizers and pesticides, while seeking 19

568

closed nutrient cycles and improved soil health. Economic considerations are secondary and

569

these farmers are willing to risk forgoing some of their income. They will adapt their crop and

570

animal management practices as is necessary to overcome a variety of challenges, as their

571

primary aim is to remain true to their philosophical ideal. Mostly, they are “pioneers”, as 76%

572

of the farmers included in the study who converted before 1995 are ‘committed organic’. They

573

have selected organic farming for reasons of producer and/or consumer health, as well as ethical

574

and lifestyle considerations (Tovey, 1997; Michelsen, 2001). To them organic farming cannot

575

be reduced to a set of techniques and practices, it is also a social movement and a political

576

statement.

577 578 579

Strengths and weaknesses of the decision tree method

580 581

Analyzing farmers’ decisions using the decision tree method not only allowed to identify

582

decision criteria on which the choice to remain conventional or to convert their farm to organic

583

methods was based. It also allowed to identify different farmer types which differ in their

584

rationale and approach to both conventional and organic farming. The decision tree shows that

585

not all farmers deliberately evaluate the specific technical aspects of conventional vs. organic

586

farming methods. Doing so would imply a willingness to reconsider current farming practices

587

and the values on which they are based, which the ‘committed’ farmers are not inclined to do.

588

They consider their current farming method as the only one right for them. For the ‘pragmatic’

589

farmers however, the decision tree shows that not one single criteria is decisive, but a number

590

of aspects are considered, i.e. that a conjunction of factors must be perceived as ‘right’ for a

591

farmer to convert his/her farm.

592 593

Moreover, the decision criteria as well as the tree structure suggests that it is not so much farm

594

structural characteristics in and of themselves that are decisive, but that they are mediated by

595

farmers’ perceptions and values. Indeed, the loops in the tree show that it is not decisive

596

whether or not a farmer keeps animals or has a vineyard, what is decisive is how he/she

597

perceives the implications of a conversion and what alternative solutions to perceived obstacles

598

he/she is willing to consider. The decision tree thus counters a determinist view of farmer

599

decision making which assumes that structural factors determine farmers’ behavior. As Long 20

600

and van der Ploeg (1994) point out, even though farmers may experience the same overall

601

structural conditions, it is possible for each farmer to choose a very different strategy depending

602

on his/her individual values and priorities.

603 604

Regarding the identified decision criteria, it is necessary to ensure that the reported reasons for

605

conversion are as close as possible to those that were decisive at the time when the decision was

606

taken, and not significantly influenced by experiences with organic farming after conversion

607

took place. This is difficult to ascertain, particularly for those farmers who have converted years

608

ago. Indeed, farmers’ attitudes are likely to change and evolve once organic production is

609

attempted (Wilson and Hart, 2001; Padel, 2002), and the relation between motivation and

610

conduct can be seen as one of mutual influence (Schoon and Te Grotenhuis, 2000). This

611

dynamic nature is supported by Rigby et al. (2001), who point out that explanatory variables

612

may change not only from one farmer to another, but also over time. Even if the risk of bias can

613

be minimized through careful interviewing, some influence is likely. However, if farmers give

614

strongly biased answers regarding the criteria used in their decision to convert, the decision tree

615

would yield a high error rate when tested. Thus, testing the decision tree with an independent

616

sample allows to ensure the validity of the decision criteria, and thereby supports the

617

effectiveness of the method.

618 619

Despite the strength in revealing a number of aspects of the decision to convert or not to

620

convert to organic agriculture, as well as the structure of the decision process, the method also

621

has some limitations.

622 623

First, although the interviewing at the first stage of data collection allows for a rich picture of

624

the decision process, the criteria must then be reduced to dichotomous questions, thus

625

eliminating the complexities that are often present in individual cases. The structure of the

626

decision tree thereby severely limits the nuances that can be included. With its unidirectional

627

arrows, the decision tree also gives the impression of a deterministic, static and linear decision

628

process, which is not implied. The decision tree only reflects a snapshot, i.e. the status at one

629

point in time. Change and learning processes, while certainly present, cannot be appropriately

630

captured in decision trees.

631 21

632

Second, as with the strengths, the limits inherent in case studies also apply. The specificity of

633

the decision criteria, which leads to the high accuracy of the predicted behavior of the test

634

sample, also means that the applicability of the decision tree is site- and time-specific and

635

findings cannot be generalized readily. Indeed, given the implicit or explicit influence of

636

external factors (e.g. agro-climatic situation, market and policy environment), spatial and

637

temporal comparisons are difficult.

638 639

Third, decision trees cannot appropriately capture the influence of personality traits, although

640

the literature indicates that individual psychological differences can influence behavior

641

(McGregor et al., 1996; Willock et al., 1999; Austin et al., 2001; Nuthall, 2001). Indeed,

642

Regouin (2002) argues that conversion to organic agriculture depends on traits like curiosity,

643

flexibility, and the willingness to take risks, as well as persistence and creativity in exploring

644

innovative marketing approaches. However, since personality traits are not a decision criteria

645

for individual farmers, this type of factors cannot be included in the decision tree. The influence

646

of personality traits such as risk aversion can thus only be inferred from farmers’ assessment of

647

various decision criteria.

648 649 650

CONCLUSION

651 652

The study supports research showing that farmers in general and potential converters in

653

particular are not one homogeneous group. While farming methods are, to some extent,

654

influenced by issues related to technical aspects of agricultural production and farm structure,

655

personal values play an important role in decision-making. The identified farmer types should

656

not conceal the complexity of circumstances by which growers enter into organic production.

657

However, they can help to better understand the attitudes and motives on which distinct farmer

658

types base their decision, i.e. recognize the relationship between farmers’ values and the

659

heterogeneity of farming practices.

660 661

This has implications on the strategy to promote organic farming and achieve policy goals.

662

Understanding how organic farming fits into the diverse strategies of farmers could allow to

663

modulate policy measures to fit these strategies. Market segmentation, e.g. based on farming 22

664

styles, could also allow to target extension programs and communications to particular farmer

665

audiences (Thomson, 2001). These could be promising approaches, particularly once the rate of

666

adoption slows as is currently the case in Austria. To support the development of organic

667

farming, further research should allow for diversity, instead of attempting to identify one or

668

several most important criteria for conversion, assuming these apply to all farmers.

669

Acknowledging farmers’ multiple realities and strategies would thus allow to shift the attention

670

on how organic farming is mediated by farmers, how they transform and reconstruct its

671

meaning to fit their farming rationale.
