| In periurban areas agriculture can assume a multifunctional role that includes landscape conservation, sustainable resource management, biodiversity conservation, leisure activities, and can also maintain adequate conditions in densely populated areas for a safe and habitable environment. This study investigates the effects of the introduction of single farm payment on the periurban agricultural area in the plain of the City of Assisi, an area with a strong landscape value. A survey was carried out to determine: changes in production, changes on farm incomes, structural adjustments, the level of multifunctionality of periurban agriculture. Moreover, a survey of 355 residents was made to assess their willingness to pay for some positive externalities of the... |

| Carbon terrestrial sinks are often seen as a low-cost alternative to fuel switching and reduced fossil fuel use for lowering atmospheric CO2. To determine whether this is true for agriculture, one meta-regression analysis (52 studies, 536 observations) examines the costs of switching from conventional tillage to no-till, while another (51 studies, 374 observations) compares carbon accumulation under the two practices. Costs per ton of carbon uptake are determined by combining the two results. The viability of agricultural carbon sinks is found to vary by region and crop, with no-till representing a low-cost option in some regions (costs of less than $10/tC), but a high-cost option in others (costs of $100-$400/tC). A particularly important finding is that... |

| Fruit production is an activity of great importance in the Brazilian commercial balance and even more in the Northeastern region. Intermediation is a regular practice in the fruit exporting market due to existence of requirements, such as quality certificates, and of internal problems in production and commercialization, such as credit limitations and absence of product standardization. Large companies, cooperatives, associations and NGOs receive products from many small producers and export them together with their own products. In Northeast, it is common that the exporting agent offers contracts to producers that include technical, administrative and legal assistance plus input supply. This paper proposes a model, using the principal-agent approach of... |

| The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nstochastic ‘‘limited’’ stochastic. In this study, we estimate rye– ryegrass yield functions in which all parameters are random. The three functional forms considered are the linear response plateau, the quadratic, and the Spillman-Mitscherlich. Nonstochastic yield models are rejected in favor of stochastic parameter models. Quadratic functional forms fit the data poorly. Optimal nitrogen application recommendations are calculated for the linear response plateau and Spillman-Mitscherlich. The stochastic models lead to smaller recommended levels of nitrogen, but the economic benefits of using fully stochastic crop yield functions are small because... |

| Industry-academic partnerships are described and discussed from the perspective of industry. Eight types of partnerships are discussed, including internships, mentoring, site visits, faculty-directed research, student research, consulting, in-class visits, and industry advisory boards. The benefits, problems, costs, motivation to participate, and advice for managing industry-academic partnerships are presented. |

| Polish rural areas, compared to other EU-25 member states, still show a high agricultural employment due to a lack of job opportunities in other rural economic sectors. In particular, in South-eastern Poland the shut down of heavy industry companies in the early 1990s left many rural inhabitants only with small incomes from their peasant farms or pensions. In the commune Ba³tów (South-eastern Poland) in order to counteract these developments, local development associations and a regional partnership undertook initiatives to stimulate the regional economy by creating a tourism infrastructure. This paper presents a case study, conducted in Ba³tów, which analyses local problems, development chances, and experience with local endogenous initiatives. The main... |

| Due to the growing demands of customers and several food crises, quality assurance schemes have become increasingly popular in agribusiness. With this trend in mind, it seems worthwhile to take a closer look at the satisfaction of participating European companies. The study focuses on the IFS, which has gained much relevance in the food industry. A questionnaire concerned with perceptions of the advantages and disadvantages of the IFS was answered by 389 companies. The results indicate that the overall evaluation of the IFS is primarily affected by the perceived usefulness of the catalogue of requirements and its evaluation. Furthermore, a cluster analysis was conducted and three clusters were identified, representing heterogeneous evaluations of the IFS. |
