RESUMO

Brazil is one of the main users of chemical pesticides in the world. These products threaten human and environmental health, and many of them are prohibited in countries other than Brazil. This paradigm exists in contrast with worldwide efforts to make the need for food production compatible with biodiversity conservation, preservation of ecosystem services, and human health. In this scenario, the development of sustainable methods for crop production and pest management such as organic agriculture and biological control are necessary. Herein, we describe how the process of registration of natural enemy-based products in organic agriculture is simpler and faster than the conventional route of chemical insecticides and can favor the development of the biological control market in Brazil. Since the regulatory mechanisms have been established in Brazil for organic agriculture, the number of biological control products registered has increased exponentially. Today, 50 companies and associations are marketing 16 species/isolates and 95 natural enemy-based products. Although this scenario presents a series of new opportunities to increase and stimulate a more sustainable agriculture in the country, biological control is not always aligned with the aims and philosophy of organic agriculture and agroecology. Therefore, we also argue that new research efforts are needed on understanding how conservation biological control strategies can be integrated with augmentation biological control to promote a sustainable agriculture under the concepts of organic agriculture and agroecology.

RESUMO

Organic agriculture (OA) is considered a strategy to make agriculture more sustainable. Bhutan has embraced the ambitious goal of becoming the world's first 100% organic nation. By analysing recent on-farm data in Bhutan, we found organic crop yields on average to be 24% lower than conventional yields. Based on these yield gaps, we assess the effects of the 100% organic conversion policy by employing an economy-wide computable general equilibrium (CGE) model with detailed representation of Bhutan's agricultural sector incorporating agroecological zones, crop nutrients, and field operations. Despite a low dependency on agrochemicals from the onset of this initiative, we find a considerable reduction in Bhutan's GDP, substantial welfare losses, particularly for non-agricultural households, and adverse impacts on food security. The yield gap is the main driver for a strong decline in domestic agricultural production, which is largely compensated by increased food imports, resulting in a weakening of the country's cereal self-sufficiency. Current organic by default farming practices in Bhutan are still underdeveloped and do not apply the systems approach of organic farming as defined in the IFOAM organic farming standards. This is reflected in the strong decline of nitrogen (N) availability to crops in our simulation and bears potential for increased yields in OA. Improvement of soil-fertility practices, e.g., the adoption of N-fixing crops, improved animal husbandry systems with increased provision of animal manure and access to markets with price premium for organic products could help to lower the economic cost of the large-scale conversion.

RESUMO

Agricultural industrialisation and globalisation have steadily increased the transportation of food across the world. In efforts to promote sustainability and self-sufficiency, organic milk producers in Sweden are required to produce a higher level of cattle feed on-farm in the hope that increased self-sufficiency will reduce reliance on external inputs and reduce transport-related greenhouse gas emissions. Using data collected from 20 conventional and 20 organic milk producers in Sweden this paper aims to assess the global warming impact of farmyard vehicles and the transportation of feed produced 'off-farm' in order to compare the impact of vehicle-related emissions from the different production methods. The findings show organic and conventional production methods have different vehicle-related emission outputs that vary according to a reliance on either road transportation or increased farmyard machinery use. Mechanical weeding is more fuel demanding than conventional agrichemical sprayers. However, artificial fertilising is one of the highest farmyard vehicle-related emitters. The general findings show organic milk production emits higher levels of farm vehicle-related emissions that fail to be offset by reduced emissions occurring from international transport emissions. This paper does not propose to cover a comprehensive supply chain carbon footprint for milk production or attempt to determine which method of production has the largest climatic impact. However, it does demonstrate that Sweden's legal requirements for organic producers to produce more feed on-farm to reduce transport emissions have brought emissions back within Sweden's greenhouse gas inventory and raises questions around the effectiveness of policies to reduce vehicle-related emissions. Further research is needed into the effectiveness of climate change mitigation on food production policies, in particular looking at various trade-offs that affects the entire food supply chain.

RESUMO

Plant biostimulants are borderline substances that play an intermediate role between plant protection products and fertilisers. At present, such substances are regulated by national laws and have different names in the various European Member States. The aim of this paper is to provide an overview on the activity of these substances and on the national laws that regulate them, as they vary considerably from one Member State to another. The greatest difficulty in terms of the correct regulatory framework for these substances is related to their heterogeneity. This situation creates uncertainties for operators, control authorities and bodies that certify and control the organic production, and strongly limits the growth of these substances. This problem will be overcome with the amendment of Regulation EC No 2003/2003 which will shortly extend its scope to the category of plant biostimulants included within the fertilising additives.

RESUMO

Americans are in the midst of a food-consciousness revival: on television, in the mouth of the First Lady, in endless articles celebrating urban agriculture can be found a sudden enthusiasm for the politically and, perhaps, spiritually curated dinner table. In this special section, writers explore the perilous state of food and food politics in America and a wide range of responses on the Left. Marion Nestle, in her essay on the farm bill, describes how the existing policy disaster came to be, along with the relationship between Reagan-era deregulation and the obesity epidemic. Mark Engler describes both the successes and coopting of the strands of left-wing responses­buying organic, eating local, and agitating for fair trade­and asks, "What's a radical to eat?" Laurie Woolever uncovers the kind of labor exploitation endemic to the elite dining experience. Karen Bakker Le Billon compares American to French school lunches, unpacking the relationship between food and citizenship. Juliana DeVries explores vegetarianism and the politics of everyday life.

RESUMO

In the fall of 2011, I taught a graduate food studies course at New York University devoted to the farm bill, a massive and massively opaque piece of legislation passed most recently in 2008 and up for renewal in 2012. The farm bill supports farmers, of course, but also specifies how the United States deals with such matters as conservation, forestry, energy policy, organic food production, international food aid, and domestic food assistance. My students came from programs in nutrition, food studies, public health, public policy, and law, all united in the belief that a smaller scale, more regionalized, and more sustainable food system would be healthier for people and the planet.

RESUMO

Organic farming has been hijacked by big business. Local food can have a larger carbon footprint than products shipped in from overseas. Fair trade doesn't address the real concerns of farmers in the global South. As the food movement has moved from the countercultural fringe to become a mainstream phenomenon, organic, local, and fair trade advocates have been beset by criticism from overt foes and erstwhile allies alike. Now that Starbucks advertises fair trade coffee and Kraft owns Boca soy burgers, it's fair to ask, "What's a radical to eat?"

RESUMO

Animal health (AH) defines the outcome of their inspections of livestock holdings as full compliance with the legislation and welfare code (A), compliance with the legislation but not the code (B), non-compliance with legislation but no pain, distress or suffering obvious in the animals (C) or evidence of unnecessary pain or unnecessary distress (D). The aim of the present study was to investigate whether membership of farm assurance or organic certification schemes was associated with compliance with animal welfare legislation as inspected by AH. Participating schemes provided details of their members, past and present, and these records were matched against inspection data from AH. Multivariable multilevel logistic binomial models were built to investigate the association between compliance with legislation and membership of a farm assurance/organic scheme. The percentage of inspections coded A, B, C or D was 37.1, 35.6, 20.2 and 7.1 per cent, respectively. Once adjusted for year, country, enterprise, herd size and reason for inspection, there was a pattern of significantly reduced risk of codes C and D compared with A and B, in certified enterprises compared with the enterprises that were not known to be certified in all species.

RESUMO

Campus sustainable food projects recently have expanded rapidly. A review of four components - purchasing goals, academic programs, direct marketing, and experiential learning - shows both intent and capacity to contribute to transformational change toward an alternative food system. The published rationales for campus projects and specific purchasing guidelines join curricular and cocurricular activities to evaluate, disseminate, and legitimize environmental, economic, social justice, and health concerns about conventional food. Emerging new metrics of food service practices mark a potential shift from rhetoric to market clout, and experiential learning builds new coalitions and can reshape relations with food and place. Campus projects are relatively new and their resilience is not assured, but leading projects have had regional, state, and national impact. The emergence of sustainability rankings in higher education and contract-based compliance around purchasing goals suggests that if support continues, higher education's leadership can extend to the broader agrifood system.

RESUMO

This article examines the characteristics of and reasons for Norwegian farmers' ceasing or planning to cease certified organic production. We gathered cross-sectional survey data in late 2007 from organic farmers deregistering between January 2004 and September 2007 (n=220), and similar data from a random sample of farmers with certified organic management in 2006 (n=407). Of the respondents deregistering by November 2007, 17% had quit farming altogether, 61% now farmed conventionally, and 21% were still farming by organic principles, but without certification. Nearly one in four organic farmers in 2007 indicated that they planned to cease certification within the next 5-10 years. From the two survey samples, we categorised farmers who expect to be deregistered in 5-10 years into three groups: conventional practices (n=139), continuing to farm using organic principles (uncertified organic deregistrants, n=105), and stopped farming (n=33). Of the numerous differences among these groups, two were most striking: the superior sales of uncertified organic deregistrants through consumer-direct marketing and the lowest shares of organic land among conventional deregistrants. We summarised a large number of reasons for deregistering into five factors through factor analysis: economics, regulations, knowledge-exchange, production, and market access. Items relating to economics and regulations were the primary reasons offered for opting out. The regression analysis showed that the various factors were associated with several explanatory variables. Regulations, for example, figured more highly among livestock farmers than crop farmers. The economic factor strongly reflected just a few years of organic management. Policy recommendations for reducing the number of dropouts are to focus on economics, environmental attitudes, and the regulatory issues surrounding certified organic production.

RESUMO

Drawing on a pragmatic approach, this paper provides an analysis of government support for organic farming in Ireland. Varying levels of encouragement and programmes are provided to farmers in their conversion from conventional to organic production, and in their maintenance of organic production. As support policies vary across regions and are linked to European Union legislation, it is challenging to document the many types of support in place. This paper investigates relevant technical, financial, and policy support available to organic farmers in Ireland. As an exploratory study, it develops an assessment of Ireland within eight key categories of organic agricultural support: policy, leadership, technical support, financial support, research, education and information, marketing and promotion, and future outlook. Information and data from the Irish Department of Agriculture, Fisheries and Food (DAFF), the Irish Agriculture and Food Development Authority (Teagasc), and other government and semi-governmental agencies were utilized to assess the level of support in each category. This assessment provides key findings which will allow policymakers, organizations and citizens to better understand the current situation and set a path for the future development of organic farming in Ireland.

RESUMO

This paper documents the early evolution of UK organic food and farming policy networks and locates this empirical focus in a theoretical context concerned with understanding the contemporary policy-making process. While policy networks have emerged as a widely acknowledged empirical manifestation of governance, debate continues as to the concept's explanatory utility and usefulness in situations of network and policy transformation since, historically, policy networks have been applied to "static" circumstances. Recognizing this criticism, and in drawing on an interpretivist perspective, this paper sees policy networks as enacted by individual actors whose beliefs and actions construct the nature of the network. It seeks to make links between the characteristics of the policy network and the policy outcomes through the identification of discursively constructed "storylines" that form a tool for consensus building in networks. This study analyses the functioning of the organic policy networks through the discursive actions of policy-network actors.
