    Sustainable intensification of smallholder farming is a serious option for satisfying 2050 global cereal requirements and alleviating persistent poverty. That option seems far off for Sub-Sahara Africa (SSA) where technology-driven productivity growth has largely failed. The article revisits this issue from a number of angles: current approaches to enlisting SSA smallholders in agricultural development; the history of the phenomenal productivity growth in the USA, The Netherlands and Green Revolution Asia; and the current framework conditions for SSA productivity growth. This analysis shows that (1) the development of an enabling institutional context was a necessary condition that preceded the phenomenal productivity growth in industrial and Green Revolution countries; and that (2) such a context is also present for successful SSA export crop production, but that (3) the context is pervasively biased against SSA’s smallholder food production. The article traces the origins of technology supply push (TSP) as a dominant paradigm that hinders recognition of the role of enabling institutions. The article then reviews the literature on institutional change and zooms in on Innovation Platforms (IPs) as a promising innovation system approach to such change. We describe the concrete experience with IP in the Sub-Sahara Challenge Program (SSA-CP) and in the Convergence of Sciences: Strengthening Innovation Systems (CoS-SIS) Program. The former has demonstrated proof of concept. The latter is designed to trace causal mechanisms. We describe its institutional experimentation and research methodology, including causal process tracing. --------------------------------------------------------------------------------

    This chapter investigates, theoretically as well as empirically, the way in which initiatives aimed at territorial governance work out in practice. The concept of territorial governance has increasingly received attention in policy plans as well as in the policy science literature. So far, little is known about how espoused shifts towards territorial governance manifest themselves in practice. By analysing the shift in governance in the Drentsche Aa in the Netherlands, this chapter sheds light on what happens when the espoused shift to territorial governance is applied to concrete situations, in which different dilemmas and opposing forces are at play. It shows that territorial governance in the Drentsche Aa area is struggling with tensions between regional multi-actor practices and hierarchical policy practices. We conclude that shifts in governance indeed occurred in this area, but that they manifested themselves in practice as hybrids between area based hierarchy and multi actor initiatives. As such the shifts are not as straightforward and unambiguous as sometimes thought and/or aimed for in literature, but instead their manifestation in practice is complex, ambiguous and context dependent

    Despite a significant growth in food production over the past half-century, one of the most important challenges facing society today is how to feed an expected population of some nine billion by the middle of the 20th century. To meet the expected demand for food without significant increases in prices, it has been estimated that we need to produce 70-100 per cent more food, in light of the growing impacts of climate change, concerns over energy security, regional dietary shifts and the Millennium Development target of halving world poverty and hunger by 2015. The goal for the agricultural sector is no longer simply to maximize productivity, but to optimize across a far more complex landscape of production, rural development, environmental, social justice and food consumption outcomes. However, there remain significant challenges to developing national and international policies that support the wide emergence of more sustainable forms of land use and efficient agricultural production. The lack of information flow between scientists, practitioners and policy makers is known to exacerbate the difficulties, despite increased emphasis upon evidence-based policy. In this paper, we seek to improve dialogue and understanding between agricultural research and policy by identifying the 100 most important questions for global agriculture. These have been compiled using a horizon-scanning approach with leading experts and representatives of major agricultural organizations worldwide. The aim is to use sound scientific evidence to inform decision making and guide policy makers in the future direction of agricultural research priorities and policy support. If addressed, we anticipate that these questions will have a significant impact on global agricultural practices worldwide, while improving the synergy between agricultural policy, practice and research. This research forms part of the UK Government's Foresight Global Food and Farming Futures project.

    Can agricultural research help to enlist smallholders and their resources for global food security? The Convergence of Sciences (CoS) research programme in Benin and Ghana (2002-2006) tested the impact of technology development, using a pathway for impact which featured 'technographies', diagnostic studies, and farmer-experimenter groups to ensure appropriateness. Within the existing small windows of opportunity only marginal improvements proved possible. The CoS team realised and partly tested the notion that innovation is predicated upon change of the institutions that frame opportunity. The sequel to CoS (2008-2013) uses an innovation system approach to pursue cross-system institutional change. Keywords: Globalisation; Governance; Social sector; Technology

    dehalococcoides sp strain - reductive dehalogenase genes - vinyl-chloride reductase - real-time pcr - chlorinated ethenes - ethenogenes strain-195 - enrichment culture - cis-dichloroethene - flow column - trichloroethene
    Monitoring and quantification of organohalide respiring bacteria is essential for optimization of on-site bioremediation of anoxic subsurface sites contaminated with chloroethenes. Molecular monitoring and model simulations were applied to determine degradation performance of an in situ dechlorinating bioreactor and its influence on the contamination plume. Dehalococcoides was the dominant dechlorinating microorganism as revealed by qPCR targeting 16S rRNA- and chloroethene reductive dehalogenase-encoding genes (tceA, vcrA, bvcA). The presence of all three reductive dehalogenases genes indicated coexistence of several distinct organohalide respiring bacterial populations in the bioreactor and groundwater. Mass balancing revealed that main dechlorinating activities were reduction of cis-dichloroethene and vinyl chloride. Analysis of growth kinetics showed that when performance of the bioreactor improved due to especially the addition of molasses, dechlorinating microorganisms were growing close to their maximum growth rate. Once near-complete dehalogenation was achieved, Dehalococcoides only grew slowly and population density did not further increase. The bioreactor influenced dechlorinating populations in the plume with subsequent decrease in chlorinated compound concentrations over time. In the present study, a combination of molecular diagnostics with mass-balancing and kinetic modeling improved insight into organohalide respiring bacteria and metabolite dynamics in an in situ dechlorinating bioreactor and showed its utility in monitoring bioremediation

    Research on successful change often leads to a normative model. What was an empirical outcome becomes a prescription for action. In water management, research on platforms for decision-making, multi-stakeholder processes, social learning, and participatory interventions seems to have made this step to new orthodoxy. Compared to agricultural development, where many still expect technology (smart farming, precision farming, genomics, etc.) to provide the necessary answers to the challenges of anthropogenic biosphere change, thinking about water solutions seems to have moved on and embraced a new normative model that sees necessary action as emerging from the interaction (deliberation, negotiation, conflict resolution, etc.) of multiple stakeholders. However positive this development, the seriousness of the challenges posed by the fact that people have become a major force of nature that is rapidly altering the flimsy and fragile biosphere, compels us to ask whether the normative model can handle these challenges. Some points that will be considered are: (1) inequalities of power among stakeholders, (2) the disproportional influence of vested interest, (3) higher-level institutional conditions and incentive structures, (4) compromises that undermine efficacious action, (5) and institutions that are geared to economic growth, not to prudent water use (incompatibility between hydrological cycle and linear growth). The paper attempts to examine these issues and to draw some implications for water professionals.
