An analytical approach to the implementation of genetically modified crops Kristian Borch and Birgitte Rasmussen Public scepticism towards genetically modified (GM) crops is increasing. To address this, the risks and benefits of GM crops must be examined across scientific disciplines, and be discussed with the authorities, the agricultural industry and the consumers. In a feasibility study we have systematically analysed the challenges of the development and marketing of GM crops in Europe. A life-cycle inventory was used together with established technology foresight techniques in an interdisciplinary and empirical framework. The approach taken in this study established a dialogue between stakeholders and provided a framework for discussions about the future direction of GM crops.

he strong public scepticism that the commercialization of genetically modified (GM) crops already faces in Europe might soon spread to other parts of the world. Therefore, it is timely to examine the consequences of GM crops from the perspective of society as well as of industry. In this article, we suggest the use of technology foresight (TF), which is a prospective and transparent framework, to analyse the future use of the rapidly progressing scientific field of GM crops. TF is the process and dialogue involved in systematically attempting to look into the longer-term future of science, technology, economy and society, with the aim of identifying areas of strategic research. TF is concerned with the infrastructure necessary to recognize and exploit technological opportunities as they emerge1,2. This framework cannot predict the future but it does enable an organization to learn, adapt and enrich the ongoing strategic discussion.

Public acceptance The prevailing presumption made by the biotechnology industry is that the public hesitancy about the use of GM crops can be counteracted by consumer education and the establishment of scientific credibility for companies engineering GM crops3. However, this assumption is probably erroneous. First, increased knowledge of gene technology and its risks and benefits are not likely to affect ethical concerns4 or anxiety about the potential monopoly of multinational biotechnology companies5. Second, the establishment of scientific credibility is not likely to ease consumer concerns because uncertainty will be deliberately sought out and maximized by experts on each side of areas of conflict. The reason for the public scepticism towards GM crops is an uncertainty about the longer-term risks and consequences of growing GM crops. This creates uncertainty for the biotechnology industry and the authorities because they lack clear signals about whether or not society will accept the technology. It is a political responsibility to express a standpoint and to make decisions on these uncertainties on behalf of the K. Borch ([email protected]) and B.

consumers and in accordance with the common understanding of societal risk acceptance. However, society, politicians and the responsible authorities have difficulties in reaching a consensus about the coverage and application of risk assessments concerning GM crops. Society and risk analysis When analysing risks today, we face a new type of uncertainty about our future6. New technologies, such as genetic engineering, and their possible consequences pose new challenges to our foresight. Scientists do not agree about their consequences to ecosystems, health and the environment, and, where scientists disagree, policy makers find themselves in an uncertain position to take decisions about the future7. A central issue in a prospective study related to genetic engineering is the risk and uncertainty aspects related to the GM crops. Two prominent social theories have been shaping the discourse of environmental politics during recent years: the risk society theory and the theory of ecological modernization. Ulrick Beck’s risk society theory uses gene technology as an example of the nature of risk we face today. He argues that the focus is more and more on hazards which are neither visible nor perceptible to the victims; hazards that in some cases may not even effect within the life spans of those affected, but instead during those of their children; hazards in any case require the ‘sensory organs’ of science – theories, experiments, measuring instruments – in order to become visible or interpretable at all8. Modern industrial societies are changing from being based on the distribution of ‘goods’ (materials, products) to being based on the distribution of ‘bads’ (risks). The authorities are no longer able to guarantee safety from risks because genetic engineering (for example), in contrast to early industrial risks, cannot be limited in time or place and are not accountable to established rules of causality, blame and liability, and cannot be compensated for or insured against. By contrast, the theory of ecological modernization9 outlines a hyper-rational strategy for correcting the ecological flaws of contemporary production and consumption practices. Ecological modernists emphasize the role of strict governmental regulations in promoting

innovation in environmental technology. The key element in executing this transformation is switching over to the use of cleaner, more efficient and less resource intensive technologies through a process of ‘super-industrialization’. Ecological modernization relies on the implementation of anticipatory planning practices (the precautionary principle). The successful execution of this approach depends on the organizational internalization of ecological responsibility. Cohen has attempted to formulate the risk society and ecological modernization perspec-tives into a unified theory of social transformation9.

The scenarios can then be constructed stepwise, thus reducing the complexity of writing the scenario and also reducing the numbers of scenarios needed because the preceding scenarios restrict the scenarios that are possible in the next category.

grass and how certain the outcomes would be in the following categories: (1) corporate research and development; (2) public acceptance; (3) farmer acceptance; and (4) marketing of GM crops. Furthermore, the respondents were asked to rank their expertise inside each category as expert, knowledgeable or layperson. The most important driving forces are those that have a direct influence on the future demand for GM grass but whose outcome is uncertain. Figure 2 shows the most significant of these driving forces selected by the respondents who ranked themselves as either experts or knowledgeable inside a specific category. It is important to have identified a number of scenarios (two to seven scenarios are often considered to be the optimum) in order to give the decision makers the opportunity to monitor trends and to be prepared for alternative developments in technology, marked and legislation. The uncertainty interval of the driving forces (Fig. 2) can be used to construct these multiple scenarios. Schnaars has suggested four different approaches that can be adopted when designing a strategy with multiple scenarios13: (1) a robust strategy that performs well over the full range of scenarios considered; (2) a flexible strategy that keep options open for as long as possible and considers the cost of postponing a decision; (3) a multiple-coverage strategy that simultaneously

pursues multiple strategies using extensive resources until the future becomes clear; and (4) a gambling strategy in which the strategy is selected by gambling on the development of other futures in which it produces more than proportional returns. A trend scenario, which describes the development of the present from certain trends, could also be useful. From a more general perspective of the public acceptance of GM crops, the combined industry must collaborate with the authorities in developing threat and conflict scenarios (worst-case scenarios), which can elaborate on possible concerns and their causes. We will not describe the scenario process in detail here but Schwarts has given a guide to scenarios and the process of creating them14. Conclusions The overall experience from this exercise is that the TF process assists a dialectical debate by reducing the comprehensibility gap between different scientific disciplines and between different stakeholders, in a learning process. Moreover, TF identifies who has the responsibility of taking the appropriate decisions, considering both scientific and ethical matters. It thus prevents the erosion of public trust in established institutions, science and the biotechnology industry. Finally, the study reveals the societal necessity to reach a consensus about coverage and application of risk assessment on GM crop technology. References 1 Georghiou, L.
