    The Introduction of thousands of tonnes of glyphosate in the food chain - an evaluation of glyphosate tolerant soybeans

    Glyphosate-tolerant (GT) soybeans dominate the world soybean market. These plants have triggered increased use of, as well as increased residues of, glyphosate in soybean products. We present data that show farmers have doubled their glyphosate applications per season (from two to four) and that residues of late season spraying of glyphosate (at full bloom of the plant) result in much higher residues in the harvested plants and products. GT soybeans produced on commercial farms in the USA, Brazil and Argentina accumulate in total an estimated 2500–10,000 metric tonnes of glyphosate per year, which enter global food chains. We also review studies that have compared the quality of GT soybeans with conventional and organic soybeans. Feeding studies in Daphnia magna have shown dose-related adverse effects (mortality, reduced fecundity and delayed reproduction) of glyphosate residues in soybeans, even at glyphosate concentrations below allowed residue levels. We argue that GT soybeans need to be tested in fully representative and realistic contexts. However, the current risk assessment system has only required and received data from field trials with beans that were sprayed with much lower doses of glyphosate as compared to contemporary commercial farms. This has left knowledge gaps and a potentially serious underestimation of health risks to consumers.publishedVersio

    Reforming the Global Food and Agriculture System: Towards a Questioning Agenda for the New Manifesto

    Get PDF
    In the face of the pressing challenges posed by hunger, malnutrition and the vulnerability of our food system, it is imperative that radical reforms to the food system are articulated and implemented. Questions about the governance of the current food system need to be posed and answered. Key issues that need to be addressed include the direction of innovation and technological choices, the distribution of costs and benefits amongst producers, consumers and our environment, and the diversity and characteristics of possible socio-technical pathways that could be lead to more sustainable and socially just food futures. This paper presents some ideas on what a comprehensive strategy for reforming the global food and agriculture system might look like, in light of those questions about directionality, distribution and diversity.ESR

    Silver Bullets, Grand Challenges and the New Philanthropy

    Get PDF
    Whether generic ‘silver bullet’ solutions can address complex development problems has been debated for many years. The ‘grand challenge’ extends the idea of the silver bullet in ways that speak to a goal-driven, global development agenda and a new generation of private philanthropists – or ‘philanthro-capitalists’ seeking to apply business methods to ‘strategic’ giving. These developments raise new Sustainability challenges, explored in this paper, drawing on examples from the health and agriculture sectors. Biofortification research funded by the Bill and Melinda Gates Foundation provides a detailed, illustrative case of how these ideas can reduce space to debate directionality and accountability. Imperatives towards rapid ‘scaling up’ infer homogenous populations and overlook patterns of diversity and distributional concerns; transforming complex and diverse needs into ’demand’ for pre-defined technical solutions. This paper asks if the potential exists for a reinvigorated philanthropic sector to play a different role, and turn its power and resources towards learning processes that recognise diversity and use this to reshape programme design.ESR

    Environmental Change and Maize Innovation in Kenya: Exploring pathways in and out of maize

    Get PDF
    This paper summarises findings of the STEPS Environmental Change and Maize Innovation in Kenya project. Maize is an important staple crop in Kenya, socially, politically and economically. This project has taken maize as a window through which to explore differential responses to the combined and inter-related effects of climate change, market uncertainties and land use changes over time. It has traced innovations and responses of various actors – public agricultural research institutions, donors, development agencies, private companies and farmers. At issue is the way in which actors in different institutional, geographic and social locations understand and frame resilience – and how these framing assumptions shape agendas and steer solutions and resources in certain directions and not others.ESR

    Transforming innovation for sustainability

    Get PDF
    The urgency of charting pathways to sustainability that keep human societies within a "safe operating space" has now been clarified. Crises in climate, food, biodiversity, and energy are already playing out across local and global scales and are set to increase as we approach critical thresholds. Drawing together recent work from the Stockholm Resilience Centre, the Tellus Institute, and the STEPS Centre, this commentary article argues that ambitious Sustainable Development Goals are now required along with major transformation, not only in policies and technologies, but in modes of innovation themselves, to meet them. As examples of dryland agriculture in East Africa and rural energy in Latin America illustrate, such "transformative innovation" needs to give far greater recognition and power to grassroots innovation actors and processes, involving them within an inclusive, multi-scale innovation politics. The three dimensions of direction, diversity, and distribution along with new forms of "sustainability brokering" can help guide the kinds of analysis and decision making now needed to safeguard our planet for current and future generations
