One of the most important goals in current fisheries management is to maintain or restore stocks above levels that can produce the maximum sustainable yield (MSY). However, it may not be feasible to achieve MSY simultaneously for multiple species because of trade-offs that result from interactions between species, mixed fisheries and the multiple objectives of stakeholders. The premise in this study is that MSY is a concept that needs adaptation, not wholesale replacement. The approach chosen to identify trade-offs and stakeholder preferences involved a process of consulting and discussing options with stakeholders as well as scenario modelling with bio-economic and multi-species models. It is difficult to intuitively anticipate the consequences of complex trade-offs and it is also complicated to address them from a political point of view. However, scenario modelling showed that the current approach of treating each stock separately and ignoring trade-offs may result in unacceptable ecosystem, economic or social effects in North Sea fisheries. Setting FMSY as a management target without any flexibility for compromises may lead to disappointment for some of the stakeholders. To treat FMSY no longer as a point estimate but rather as a "Pretty Good Yield" within sustainable ranges was seen as a promising way forward to avoid unacceptable outcomes when trying to fish all stocks simultaneously at FMSY. This study gives insights on how inclusive governance can help to reach consensus in difficult political processes, and how science can be used to make informed decisions inside a multi-dimensional trade-off space. © 2016 Elsevier Ltd.

Current dynamic demand-driven networks make great demands on, in particular, the interoperability and agility of information systems. This paper investigates how reference information models can be used to meet these demands by enhancing ICT mass customisation. It was found that reference models for Production and Supply Chain Management do not yet sufficiently meet the requirements of a mass customisation approach. They have developed from isolated models based on pure standardisation and tailored customisation strategies, towards static repository-based models founded on segmented standardisation strategies. Existing models provide valuable knowledge for developing towards more dynamic reference information models, including the progress made by ERP vendors to make their reference models configurable. Important remaining challenges are setting up reference information models as generic models that define classes of architectures, and incorporating user-friendly means that guide users through the process of configuring specific information models. © 2010 Elsevier B.V.

In The Netherlands co-management of nature and landscapes requires a more entrepreneurial approach, both from societal organisations and businesses. In this paper we describe the results from a literature review and interviews with five nature and landscape organisations and twelve businesses. The interviews focus on their potential to collaborate and shows mainly an exchange of image and finances and less exchange of knowledge and networks. In order to exchange more, nature and landscape organisations should identify the desired input from businesses and their own unique characteristics that may interest businesses.

This paper aims to identify supply chain organization and management structures that maximize innovation in consumer driven fruit supply chains with the ultimate goal of increasing European fruit consumption. Data was collected on the chain organization, management structures and innovativeness of ten innovative fruit supply chains in Poland, Spain, Greece and The Netherlands using two questionnaires for each chain actor. The supply chains have been analysed based on a conceptual framework of mechanisms underlying supply chain management. After comparing the selected fruit supply chains against the conceptual framework, critical success factors (CSFs) were derived for fruit supply chain innovativeness. For every type of fruit chain, it is important to have a customer focus, a quality management system implementing tracking and tracing, and a lead firm in the chain that initiates, stimulates and coordinates the implementation of innovations. A typology of consumer driven innovative fruit supply chains is proposed based on the different combinations of network use and formality of the innovation strategy in the chains. The choice of type for a chain depends on the entrepreneurial style, type of product (fresh or processed) and size of the companies. The guidelines support the identification of CSFs.
