    Innovation systems: Implications for agricultural policy and practice

    Get PDF
    Farmers and businesses need to adapt constantly if they are to survive and compete in the rapidly evolving environment associated with the contemporary agricultural sector. Rethinking agricultural research as part of a dynamic system of innovation could help to design ways of creating and sustaining conditions that will support the process of adaptation and innovation. This approach involves developing the working styles and practices of individuals and organizations and the incentives, support structures and policy environments that encourage innovation. Previous efforts to support agricultural sector innovation largely targeted agricultural policy and research organizations. The systems approach recognizes that innovation takes place through the interaction of a broader set of organizations and activities. These patterns of interaction and working styles and practices – or institutions as they are referred to by social scientists – need to adapt continuously if they are to meet the changing demands of the evolving agricultural sector. Institutional learning is central to this process and will ensure research organizations remain relevant and continue to introduce innovations that impact positively on the livelihoods of the poor

    Biotechnology and the Politics of Truth : From the Green Revolution to an Evergreen Revolution

    This paper investigates why and how issues around the diffusion of GM technologies and products to developing countries have become so central to a debate which has shifted away from technical issues of cost-benefit optimisation in a context of uniform mass production and consumption in the North, to the moral case for GM crops to feed the hungry and aid ‘development’ in the South. Using comparison between agricultural biotechnology and the ‘Green Revolution’ as a cross cutting theme, the contributions of this paper are threefold. Firstly, by analysing biotechnology as a set of overlapping frames within a discursive formation, four frames are identified which summarise key challenges presented by biotechnology era. Secondly, the use of Foucault's concept of bio-power to synthesise key themes from the frame analysis illuminates the ‘revolutionary’ nature of the biotech revolution. Thirdly, the potential of actor-network theory to provide a tools for the empirical study of processes of (re)negotiation of nature/society relations in the context of agricultural biotechnology controversies is explored

    Who leads research productivity growth? Guidelines for R&D policy-makers

    Full text link
    [EN] This paper evaluates to what extent policy-makers have been able to promote the creation and consolidation of comprehensive research groups that contribute to the implementation of a successful innovation system. Malmquist productivity indices are applied in the case of the Spanish Food Technology Program, finding that a large size and a comprehensive multi-dimensional research output are the key features of the leading groups exhibiting high efficiency and productivity levels. While identifying these groups as benchmarks, we conclude that the financial grants allocated by the program, typically aimed at small-sized and partially oriented research groups, have not succeeded in reorienting them in time so as to overcome their limitations. We suggest that this methodology offers relevant conclusions to policy evaluation methods, helping policy-makers to readapt and reorient policies and their associated means, most notably resource allocation (financial schemes), to better respond to the actual needs of research groups in their search for excellence (micro-level perspective), and to adapt future policy design to the achievement of medium-long term policy objectives (meso and macro-level).Jiménez Saez, F.; Zabala Iturriagagoitia, JM.; Zofio, JL.

    A Critical Analysis of Atoh7 (Math5) mRNA Splicing in the Developing Mouse Retina

    Get PDF
    The Math5 (Atoh7) gene is transiently expressed during retinogenesis by progenitors exiting mitosis, and is essential for ganglion cell (RGC) development. Math5 contains a single exon, and its 1.7 kb mRNA encodes a 149-aa polypeptide. Mouse Math5 mutants have essentially no RGCs or optic nerves. Given the importance of this gene in retinal development, we thoroughly investigated the possibility of Math5 mRNA splicing by Northern blot, 3′RACE, RNase protection assays, and RT-PCR, using RNAs extracted from embryonic eyes and adult cerebellum, or transcribed in vitro from cDNA clones. Because Math5 mRNA contains an elevated G+C content, we used graded concentrations of betaine, an isostabilizing agent that disrupts secondary structure. Although ∼10% of cerebellar Math5 RNAs are spliced, truncating the polypeptide, our results show few, if any, spliced Math5 transcripts exist in the developing retina (<1%). Rare deleted cDNAs do arise via RT-mediated RNA template switching in vitro, and are selectively amplified during PCR. These data differ starkly from a recent study (Kanadia and Cepko 2010), which concluded that the vast majority of Math5 and other bHLH transcripts are spliced to generate noncoding RNAs. Our findings clarify the architecture of the Math5 gene and its mechanism of action. These results have implications for all members of the bHLH gene family, for any gene that is alternatively spliced, and for the interpretation of all RT-PCR experiments
