| According to FAO (2005) about 13 million hectares of the word’s forest are lost due to deforestation. Naoto (2006) found Africa to lead the list of countries with the highest rate of deforestation. This worrisome situation is further aggravated by the possible negative impacts of climate change due to an increase in the mean global temperature. Evidence supports that Africa is most likely to suffer the most the devastating impacts of natural calamities such as droughts and floods. This paper sought to evaluate the causes of deforestation in 27 Sub-Saharan African (SSA) countries. Our model uses annual data spanning from 1990 to 2004. Trade and urban population tend to be associated with a decline in deforestation. On the other hand, we found strong... |

| As the most intensive form of partnership in agriculture, farming collectives (FCs) place high demands on their participants. Based on a census of Swiss farming collectives, three success indicators are formed. The first and second describe interpersonal and economic success respectively, whilst the third encompasses overall success. Factors influencing success are determined by means of multiple regressions. Five predictor variables (compatibility with co-operation partner, trust, information quality, attitude of social environment, and relationship/kinship circle of the cooperation partner) accounted for 44 per cent of the variance in interpersonal success. Economic success was far more difficult to explain (R2 = 0.11). Even so, the influence of “soft”... |

| Gesetzgeber, Handel und insbesondere Verbraucher fordern vor dem Hintergrund aktueller Lebensmittelskandale unternehmensübergreifende Qualitätssicherungs- und Rückverfolgbarkeitssysteme. Den Unternehmen entstehen dadurch zusätzlicher Aufwand und Kosten, was eine zurückhaltende Akzeptanz entsprechender Systeme erwarten lässt. Bei den betroffenen Akteuren entlang der Wertschöpfungskette sind andererseits aber auch verteilte Nutzenaspekte gegeben, die schwer lokalisierbar und noch schwerer quantifizierbar sind. Der Quantifizierung dieser Nutzen und auch der Kosten von Rückverfolgbarkeitssystemen ist ein Teilprojekt des Forschungsverbunds IT FoodTrace gewidmet. Aussagen über die Wirtschaftlichkeit des IT FoodTrace Verbundes lassen sich aufgrund der erst kurzen... |

| The new institutional economics has recently developed the idea that the institutional environment can have an impact on economic actors' mental perceptions, and reciprocally, that these perceptions can impact on the institutional environment. This latter point seems particularly relevant in the field of economic organisations participation in the political making process. Nevertheless the empirical description of this role of mental perceptions in the political behaviour had not been made clearly. To contribute to this empirical description we lead a comparative study of 4 farm sectors in Costa Rica, based on a dynamic approach of mental perceptions in relation with the institutional change occurring during the liberalisation process. We carry out a... |

| This article considers the impacts of (de)coupled farm sector support on the locations of farming and agro-industrial activity. An economic geography model is developed which has two types of regions, one with extensive agricultural production (rural), the other with intensive farming that is more densely populated (urban). The farm and agro-industrial sectors are vertically linked. A service sector that is not directly linked to either basic industry is also explicit. We show that coupled and decoupled subsidies affect the spatial distribution of farming, industry, and service sector activity. Support that is provided to all farmers regardless of crop, thus semi-decoupled, increases spatial agglomeration. Support targeted to farmers of particular crops,... |

| The Israeli citrus export sector was liberalized in 1991 with the aim to increase citrus growers' income and to improve overall efficiency of the international citrus marketing channel. However, the former government export monopoly's activities were mainly taken over by four large companies accounting for over 90% of total Israeli citrus market exports. In addition, citrus exporters maintained the monopoly's consignment system, substantially limiting transparency on how the grower price is determined. This lead the government to intervene in the newly liberalized market by implementing a minimum price agreement in the 1994/95 season to protect citrus growers against exporters' abuse of market power. In this paper we analyze whether market power was... |

| It is notoriously difficult to assess the economic value of research aimed at improving research capacity, particularly in enhancing human capital. In this paper, a framework is developed and an analysis is undertaken of the value of training for scientists in wheat rust resistance in India. The value of the training is assessed through marginal analysis of the improvement in the level of disease resistence flowing from the increased capacity. On that basis, the value of programs to build human capacity through training or further education can be estimated. While such estimates need to be highly qualified, they provide a basis for quantifying the value of R&D capacity building. |

| Since the late 1990s, the number of farmer cooperatives in China has rapidly grown. The adoption of the national law on farmer professional cooperatives in 2007 has led to significant governmental support for the establishment and management of farmer professional cooperatives. This paper explores the organizational features of the newly established cooperatives as well as the services they provide to their members. Particular attention is given to the role of local entrepreneurs in grouping farmers and in acquiring support from local and regional state agencies. The paper is based on data about a group of 200 agriculture and aquaculture cooperatives in Hubei province, central China. |
