SESSION IV: DISCIPLINARY WORKING GROUP REPORTS


Socio-economic and Policy Studies Working Group - (Rapporteur: W. LOCKERETZ)

“Socio-economic and policy studies” covers a very broad range of research. Consequently, one cannot judge the strengths and weaknesses of a particular research method independently from the particular topic being studied.

Therefore, we first developed a two-dimensional classification of socio-economic and policy studies in organic farming. The first dimension is the level of the study. In increasing order, these are:

  1. Sub-farm (individual field, crop or enterprise).
  2. Whole farm.
  3. Community.
  4. Region or area.
  5. Nation.
  6. International (up to global).

The second dimension is the topics of interest. In no particular order, these are:

  1. Economic performance.
  2. Markets.
  3. Social or personal (e.g. values, attitudes).
  4. Environmental impacts.
  5. Policy issues.

The Workshop participants classified their own research according to these categories. (In this exercise, we did not attempt to cover work by others). The participants’ research has predominantly fallen into several clusters:

  1. Sub-farm or whole farm/economic performance.
  2. Regional, national or international markets.
  3. Regional, national or international policy issues.
  4. Whole farm/social or personal.

A third dimension that must also be taken into account is the goals of the study of which we identify four possibilities:

  1. Descriptive (studies that report what the current situation is in a particular aspect of organic farming, without any analysis, comparisons or considerations of alternatives).
  2. Comparative (studies that compare organic and conventional farming with regard to performance measures such as yields, economic returns or environmental impacts).
  3. Improvement (studies that try to improve the performance of an organic system according to any of these performance measures).
  4. Projects (studies that attempt to predict the future status of organic farming under various assumptions or in response to various policy scenarios).

We then listed the methods that can be used in socio-economic and policy studies and rated the appropriateness of each method for studies with each of these possible goals. Time permitted us to do this for only two of the major combinations of level and topic of interest (given above).

For farm-level economic studies, possible methods are:

The following summarizes the judgement of the group concerning the value of each of these methods for farm-level economic studies: (0 = not valuable; 1 = somewhat valuable; 2 = highly valuable):

One important qualifier for these charts is that the ratings vary by country depending on where the country stands regarding previous research on organic farming and on the size of its organic farming sector. Consequently, these ratings would also change over time in a given country.

Soil Science and Plant Nutrient Management Working Group - (Rapporteur: P. von FRAGSTEIN and H. KLOEN)

There were ten participants from eight countries: Panohkov, P.P. (Bulgaria); Holberg, N. (Denmark); Gautronneau, Y. (France); Fragstein, P. von (Germany); Kloen, H. (The Netherlands); Hansen, S. (Norway); Brunner, T., Mäder, P. and Sharp, D. (Switzerland) and Philipps, L. (United Kingdom).

The overall task of the Working Group was put into a very wide frame. Before starting discussions about the specific points, questions of general importance in the context of agricultural research were tried to be clarified:

Agricultural research:

For whom?

- For improving the farming systems (for farmers)



- For the scientific community



- For policy makers and administrative authorities




Definition of terms:


- Approach



- Methodology



- Methods




Typology of methods:


- Destructive vs. non-destructive



- Descriptive vs. non descriptive




Aim of methods:


- For analysis



- For assessment



- For diagnosis



- For prognosis



- For evaluation

As a result of the introductory discussion, the group decided to slightly reorient the task of the Session. There was general agreement among the participants that research methods should be aimed at:

A first step which is discussed below is the development of indicators for soil fertility and nutrient efficiency. This results in a list of indicators and a very provisional list of priorities.

Sustainable Plant Health Working Group - (Rapporteur: M. WOLFE)

Eight experts participated, namely: M.S. Wolfe (U.K.) - Rapporteur; S. Collaza (Italy), D. Dubois (Switzerland), E. Lammerts van Bueren (The Netherlands), R.G. McKinley (U.K.), I. Rasmussen (Denmark), T. Ruissen (Norway) and Tamm.

The group working on plant disease, pest and weed problems started by agreeing to change the name of the panel from ‘Crop Protection’ (used by pesticide organizations) to ‘Sustainable Plant Health’.

The first principle upon which all agreed, was to work primarily at the level of prevention rather than cure. This immediately implies that a reduction approach is inadequate since prevention involves the development of systems that need to be optimal for a wide range of social, environmental and economic considerations. This also highlights the difference between the essentially linear approach of conventional agriculture compared to the circularity of the organic approach, where different aspects affect and interact with other aspects. A further consequence is the need to develop a comprehensive ecological understanding of the problems encountered in consideration of pests, diseases and weeds.

However, it was recognized that the elements of a particular problem can be extracted from a system approach and then analysed in a reductionism sense, even though this may lead to problems in incorporating the research conclusions back into the system. Even more complex, however, is the concept of translating the research conclusions into a range of systems and to a range of individual farms.

This difficulty raised the question of defining the different levels at which we might work:

a) single factor analysis on field plots or in the laboratory;

b) ecologically integrative farming systems approach;

c) farmer approach, from the point-of-view of both necessary detail and of the individual unit being a specific farm.

Going from level c) to a) increases detailed understanding, but also increases the distance form the real world. Nevertheless, each level has a value for understanding and developing novel solutions, particularly from level a), to applications and the formulation of problems at level c). For level a), the group discussed the value of molecular biological and other sophisticated approaches to the research; it was generally agreed that these were acceptable provided they were used as tools and not as goals.

A SWOT (strength, weaknesses, opportunity and threats) analysis was applied to the three approaches. The points distribution was generally in favour of the level a) research approach. However, the group recognized that all three levels are required. It was clear that advantages at one level were often disadvantages at another. This also underlined the complementarity of the different levels.

The group also agreed that despite the points distribution, it was important in the short to medium term to place the first priority at level c), the farm approach, simply because this approach currently lags so far behind the others in terms of recognition, effort and understanding. It was also recognized that there are many difficulties in developing this level, for example: in the time required for adequate understanding of the problem, in finding appropriate methods of statistical analysis, in developing appropriate PhD topics and jobs and in the problem of publication and communication.

PLANT BREEDING SUB-GROUP

Organic agriculture depends on either old crop varieties or on modern varieties bred for use in non-organic agriculture, neither of which are bred for modern organic agriculture. Focused organic plant breeding would lead to major improvements in organic production, probably more so than from any other research area.

Organic breeding would select varieties and populations best fitted to organic soils and rotations and much better able to compete with weeds. Selection would also be directed to high performance of populations, mixtures and inter-crops, which are potentially capable of providing effective buffering against environmental variation.

Organic plant breeding should draw farmers back into the process from which they have been gradually excluded during this Century. Indeed, this should happen in all aspects of organic research, because of the dependence on farmer experience at higher levels of organization.

Another, major reason for concentration on plant and animal breeding, is the increase in GMOs in non-organic breeding and production. If the GMO approach develops with no increase in organic breeding, then organic farmers and growers will be cut off from sources of new varieties within the next few years.

Based on these general arguments, the Working Group agreed unanimously to form a sub-group on organic plant breeding.

A main activity of the sub-group is to organize a meeting on organic plant breeding. This will probably take place in December 1999 in The Netherlands. The organizers will be the Louis Bolk Institute (Edith Lammerts van Bueren).

A further activity of direct interest to members is the intention to organize a bid for a European research project in organic plant breeding for the Fifth Framework Programme (Prof. Jos van Damme, NL).
