From disagreements to dialogue: unpacking the Golden Rice debate

Abstract

Transgenic Golden Rice has been hailed as a practical solution to vitamin A deficiency, but has also been heavily criticized. To facilitate a balanced view on this polarized debate, we investigated existing arguments for and against Golden Rice from a sustainability science perspective. In a structured literature review of peer-reviewed publications on Golden Rice, we assessed to what extent 64 articles addressed 70 questions covering different aspects of sustainability. Using cluster analysis, we grouped the literature into two major branches, containing two clusters each. These clusters differed in the range and nature of the sustainability aspects addressed, disciplinary affiliation and overall evaluation of Golden Rice. The ‘biotechnological’ branch (clusters: ‘technical effectiveness’ and ‘advocacy’) was dominated by the natural sciences, focused on biophysical plant-consumer interactions, and evaluated Golden Rice positively. In contrast, the ‘socio-systemic’ branch (clusters: ‘economic efficiency’ and ‘equity and holism’) was primarily comprised of social sciences, addressed a wider variety of sustainability aspects including participation, equity, ethics and biodiversity, and more often pointed to the shortcomings of Golden Rice. There were little to no integration efforts between the two branches, and highly polarized positions arose in the clusters on ‘advocacy’ and ‘equity and holism’. To explore this divide, we investigated the influences of disciplinary affiliations and personal values on the respective problem framings. We conclude that to move beyond a polarized debate, it may be fruitful to ground the Golden Rice discourse in facets and methods of sustainability science, with an emphasis on participation and integration of diverging interests.Electronic supplementary materialThe online version of this article (10.1007/s11625-018-0577-y) contains supplementary material, which is available to authorized users.

Sustainable development of plant tissue culture industry: The Indian scenario

“…Several applications in agriculture, medicine and forestry have been projected by the PTC. For example, with the advancements in genetic engineering, nutrient enriched crops such as "Golden Rice" have been grown [51]. However, there is an utter requirement of drought resistant crops that may grow with minimal requirement of water.…”

Technology transfer for social benefit: Ten principles to guide the process

“…For example, white rice (as opposed to yellow rice) has high cultural value. Technological projects have often failed because a gap between science and local communities has not been bridged (Kettenburg et al, 2018).…”

Dealing With Rejection: An Application of the Exit–Voice Framework to Genome-Edited Food

“…Accordingly, a shift in the public debate can be observed—today, environmental and health risks play less of a role; rather, the focus is shifting toward issues of naturalness, problem framing and, still, patents and property rights (van Hove and Gillund, 2017; Pirscher et al, 2018). Meanwhile, the general skepticism to GM food increasingly entails questions of the purpose of and need for “technical solutions” (van Hove and Gillund, 2017), a shift that also offers striking parallels to the older Golden Rice debate (Kettenburg et al, 2018). Drawing on the wide-ranging research of Sjöberg (2002), we could see all this as evidence of the increasing attention to the wider context in which technologies are introduced, implemented, and adopted.…”

“… 4 A significant exception is Golden Rice, which was developed in a non-commercial context (though Syngenta has been involved), but has been still targeted particularly by environmental NGOs such as Greenpeace. For an in-depth study of the Golden Rice debate, see Kettenburg et al (2018). For a critical discussion of why Golden Rice has not been widely adopted, see Stone and Glover (2017).…”
