| Four different programming models dealing with the agricultural sectors in Canada, The Netherlands, Sweden and Denmark are analysed. The purpose is to construct a knowledge base for the development of a new sector model for Danish agriculture. This analysis has created a valuable set of resources for use in the development of the model. |

| In an endeavour to improve the livestock production and particularly the marketing of livestock in the Northern Communal Areas of Namibia, this study analyses the perception of livestock farmers in this regard. The findings show that the decision making is significantly influenced by numerous socio-cultural considerations, which in many cases even overshadow the economic ones. This is manifested in the low off-take percentage, the lacking interest in commercial production, and the fact that the sale price offered to the farmer is not the most important consideration when deciding to whom to sell. |

| In order to examine the significance of hygienic behavior for the tolerance to varroosis of Africanized honey bees, they were compared with non-tolerant Carniolans in tropical Brazil. Capped worker brood cells were artificially infested with living Varroa mites, and inspected some days later. Uncapping, disappearance of the introduced mite and removal of the pupa were recorded in a total of manipulated 3,096 cells during three summer seasons. The hygienic response varied between Africanized and Carniolan colonies, but this difference was significant only in one year, during which Africanized honey bees removed a significantly greater proportion of Varroa mites than European honey bees. A high proportion of the mites disappeared from artificially infested... |

| Given that the fast transformations occurred in national and international scenery point out to a necessity of gain of efficiency to increase in competitiveness to the firms, the environment which into they are and into they develop, assume a vital importance as been the supporter foundation of this development. For this environment can be understood as the process of space concentration of many correlative segments of a production chain, also called as clusterization process, which this special conformation gives to the firms special conditions to develops the superior competitive advantages than the others firms isolated. In this sense, this paper aim to arise how occurs the process of conformation of a big cluster, culminating in satisfaction of ten... |

| This study presents, motivates, and illustrates the use of a computational laboratory for the investigation of evolutionary trade network formation among strategically interacting buyers, sellers, and dealers. The computational laboratory, referred to as the Trade Network Game Laboratory (TNG Lab), is targetted for the Microsoft Windows desktop. The TNG Lab is both modular and extensible and has a clear, easily operated graphical use interface. It permits visualization of the formation and evolution of trade networks by means of real-time animations. Data tables and charts reporting descriptive performance statistics are also provided in real time. The capabilities of the TNG Lab are demonstrated by means of labor market experiments. |

| The success of multilateral negotiations in reducing explicit trade barriers has focused the attention of policy makers and other interest groups on the impact domestic policies and attitudes may have on trade flows. In the area of genetically modified goods the principal area of dispute between the U.S. and the EU involves fundamental differences in the perception of these goods and consumer attitudes towards them. The current dispute settlement mechanisms do not provide a way of dealing with this type of issue. Existing bodies were designed to deal with "producer vested" interests and so cannot deal with "legitimate" consumer concerns. The paper concludes that a new body should be established to deal with these within the ambit of the WTO. |

| A Agroecologia vem conquistando espaços, como paradigma em construção, a partir das criticas ao paradigma químico-reducionista, em crise. Envolvendo desde questões ambientais, exclusão social dos pequenos agricultores, formação e enfoques disciplinares, e a desvalorização do saber socialmente construído. Neste sentido, abordaremos neste trabalho a ‘Construção de um espaço para pensar e praticar a Agroecologia na UFRRJ e seus arredores’, realizando entrevistas com todos os envolvidos: estudantes, professores, pesquisadores e agricultores assentados, além de pesquisas em fontes primárias, em conjunto com as referências bibliográficas secundárias Observamos a conquista de espaço da Agroecologia em todos os níveis: no ensino, na pesquisa e na extensão Para sua... |

| Irrigation farmers in the lower reaches of the Vaal and Riet Rivers are experiencing substantial yield reductions in certain crops and more profitable crops have been withdrawn from production, hypothesised, as a result of generally poor but especially fluctuating water quality. In this paper secondary data is used in a linear programming model to test this hypothesis by calculating the potential loss in farm level optimal returns. The model is static with a time frame of two production seasons. Linear crop-water quality production functions (Ayers & Westcot, 1983; adapted from Maas & Hoffmann, 1977) are used to calculate net returns for the eight most common crops grown. Results show optimal enterprise composition under various water quality... |
