| The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is the most important pest of sweet cherries in Europe. The aim of our experiments was to develop a new, cost-efficient, lead chromate-free and more eco-friendly trap for monitoring and mass trapping of R. cerasi. Five different-colored yellow panels and three different trap shapes were compared to a standard Rebell® amarillo trap in three experimental orchards in 2012. Trap color F, with a strong increase in reflectance at 500–550 nm and a secondary peak in the UV-region at 300–400 nm, captured significantly more flies than the standard Rebell® amarillo trap. Yellow traps with increased reflectance in the blue region (400–500 nm) were least attractive. Trap shape was of minor... |

| Characteristics models in demand analysis capture the idea that people value goods not For the commodity itself but for the characteristics (or attributes) or embodied in the good. For example, agents may care about the fat content and the taste of different sorts of milk but not the actual type of milk. When we have fewer characteristics than types of good the theory imposes restrictions on observables. We present a revealed preference characteristics model analysis of the demand for milk in Denmark. |

| A mudança de rumo nas discussões sobre desenvolvimento que as sociedades contemporâneas estão exigindo e empreendendo, colocam cada vez mais no centro do debate e do jogo político o ideário da sustentabilidade. As propostas daí advindas se derivam e exigem uma nova visão de ciência e tecnologia. Assim, para promover uma agricultura sustentável a formação e, por conseguinte, o perfil profissional dos técnicos não pode ser o mesmo daquele conformado pela agricultura dita “moderna”, posto que o processo formativo das ciências agrárias deve apresentar transformações substanciais em suas concepções educativas e práticas de ensino. Tal processo deve levar a um perfil do profissional que extrapole os limites da especialização, com base cultural ampla e que seja... |

| O levantamento foi realizado envolvendo 28 propriedades dos municípios de Atalaia do Norte, Benjamin Constant, São Paulo de Olivença e Tabatinga, na microrregião do Alto Solimões, visando conhecer a realidade e a importância da pecuária na agricultura familiar. Foram utilizados questionários com indagações sobre reprodução e manejo do rebanho, pastagem, sanidade animal e comercialização visando caracterizar, por meio de indicadores zootécnicos, as formas como os produtores usam e manejam os recursos mobilizados no processo produtivo. A pecuária compreende a criação extensiva de bovinos (corte) em pastagens naturais e implantadas em campos de várzea. O desempenho zootécnico, em termos de produtividade é baixo. Apesar desta realidade, a pecuária é cada vez... |

| Perennial herbs can be difficult to manage because of their underground storage organs which live sheltered from observation and control. In this paper, we describe the development of a population dynamics model for two perennial weeds, Cirsium arvense and Tussilago farfara. The model is physiologically based and includes plant growth and development, and mowing as a control option. Model performance was compared with field data from monospecific stands of C. arvense in Denmark and Netherlands and of T. farfara in Denmark. Finally, optimal mowing strategies were explored with the model. |

| Este artigo analisa a contribuição do Programa Nacional de Habitação Rural (PNHR) para o desenvolvimento de territórios predominantemente rurais. A partir do estudo de sua implementação na região Oeste Catarinense, ponder sobre os avanços e as restrições desta política social. Para as análises realizadas procedeu-se a uma revisão de literatura, à busca de documentação sobre a política e sua implementação na região estudada, bem como a entrevistas com lideranças e agricultores demandantes e beneficiados por uma casa nova ou reforma. Verificou-se que o PNHR cria uma oportunidade para as famílias rurais descapitalizadas construírem ou reformarem sua casa, apesar de ser ainda restrita a sua abrangência para o conjunto dessas famílias. A reformulação do... |

| The paradox of multifunctionality is that, on the one hand, the specialized functionalities of agriculture only arise because of the functional differentiation of social systems and scientific disciplines and, on the other hand, multifunctionality can only enter as a way to mediate between conflicts, interests and fragmented knowledge when different functions and observations of functions combine. The aim of this paper is to contribute to a theoretical and methodological platform for multidisciplinary research on multifunctional farming. With the notions of polyocular cognition and polyocular communication we introduce a second order, interdisciplinary communication process that can meet the challenge of creating a shared view on multifunctional farming.... |

| Korea has trumped the world in creating the world’s first organic farming museum. The Namyangju Organic Museum is a surprise - and for several reasons. Firstly, it is surprisingly good. And secondly, it is surely surprising that the world’s first organic agriculture museum appears in Korea? It is a specialist museum of which Namyangju can be justly proud. The museum caters for a variety of ages, from youngsters to oldsters, and for a variety of interests, from casual, to practical, to scholarly. Screen-based techno-interactive exhibits are an obvious hit with children. The Namyangju Organic Museum was launched to coincide with the 17th IFOAM Organic World Congress (September - October 2011), the first such event to be held in Asia.This museum can serve... |

| At the height of his powers, Rudolf Steiner presented a two-week conference at Oxford. The ‘Oxford Holiday Conference’ was titled ‘Spiritual Values in Education & Social Life’ (Mackenzie, 1922b), and it was this 1922 conference that laid the foundations for establishing Waldorf education in Britain and from there the rest of the Anglo world. The original Waldorf School had been established in 1919 by Rudolf Steiner at the invitation of a German industrialist, Emil Molt, in Stuttgart, Germany. Steiner states that in the Waldorf School he sought "to apply the educational principles arising out of Anthroposophy”. The Stuttgart school began with 150 students and this had grown to 700 by the time of the Oxford Conference. The Oxford Conference ran from... |

| It is easy to imagine that Rudolf Steiner (1861‐1925) would be delighted with the new exhibition 'Kosmos Rudolf Steiner' at Stuttgart's modernistic Kunstmuseum. Kosmos is a major retrospective exhibition of Steiner's life and ideas. Kosmos appears 150 years after Steiner's birth, and this is a timely anniversary to present the manand his ideas, fresh to a new audience. Kosmos Rudolf Steiner is, first and foremost, a celebration of a life lived with intensity, purpose and zest. Visitors may be drawn by curiosity, and others will be drawn by familiarity. Whether it was art, agriculture, architecture or anthroposophy, whether education or eurythmy, furniture or well-‐being, Steiner touched it, and his touch has endured. After Stuttgart, the exhibition moves... |

| Farmers in the EU do not trade greenhouse gases under the Kyoto agreement. This is an empirical puzzle because agriculture is a significant contributor of greenhouse gases (GHG) in the EU and may harvest private net gains from trade. Furthermore, the US has strongly advocated land-use practices as ‘the missing link’ in past climate negotiations. We argue that farmers have relatively low marginal reduction costs and that consequences in terms of the effect on permit price and technology are overall positive in the EU Emission Trading System (ETS). Thus, we propose a project-based system for including the farming practices in the EU ETS that reduces the uncertainty from measuring emission reduction in this sector. The system encourages GHG reduction either... |

| The Brazilian land reform is a possible strategy to reduce poverty and increase social equality, but it depends on efficient public policies capable of making the peasants selfsustainable. With the goal of presenting the main socio-economic challenges of 33 rural settlements of former landless peasantsin Rio Grande do Norte State (Northeastern Brazil), we evaluated socio, economic and environmental aspects of 631 families from these settlements and 16 “Restoration Plan for Degraded Areas” (PRAD), prepared between 2007 and 2010. The emancipation of a settlement, measured through income generation, schooling level, and changes in people’s environmental habits, was not related to the age of the settlement. Also, the income of a settlement is hardly... |

| A especificidade do processo de apropriação privada de terras públicas no Brasil, após 1850, é o ponto de origem dos problemas ambientais atuais no espaço rural, isso porque foi desse período em diante que a ausência de limites ambientais se tornou a regra principal da aliança entre a concentração fundiária e o progresso técnico aplicado à agricultura, comprometendo dramaticamente outras formas de acesso, bem como o uso produtivo ou não produtivo das terras e seus recursos naturais. O estudo de caso realizado na região sudoeste do Paraná, no Sul do Brasil, no entanto, demonstra que, apesar de uma estrutura agrária mais democrática, a regra de ausência de limites ambientais também é reiterada. Naquela região, o impulso básico à degradação ambiental deve-se... |

| Runoff from clayey soils often contains abundant particulate phoshorus (PP), part of which may solubilize in surface waters. Monitoring losses of potentially bioavailable forms of PP is expensive, calling for other ways to predict them. Such predictions could be based on soil loss and available soil P indices, e.g., agronomic P status. To study correlations between P pools in runoff versus soil P saturation (by Mehlich 3 extraction; DPSM3) and acetate soil test P (PAc), 15 clayey soils of south Finland were subjected to laboratory rainfall simulation. Runoff from these simulations was analyzed for concentrations of suspended soil (TSS), dissolved molybdate-reactive P (DRP), total P (TP), and, as normalized to soil loss, potentially bioavailable forms of... |
