An acoustic view of ocean mixing

Knowledge of the parameter K (turbulent diffusivity/"mixing intensity") is a key to understand transport processes of matter and energy in the ocean. Especially the almost vertical component of K across the ocean stratification (diapycnal diffusivity) is vital for research on biogeochemical cycles or greenhouse gas budgets. Recent boost in precision of water velocity data that can be obtained from vessel-mounted acoustic instruments (vmADCP) allows identifying ocean regions of elevated diapycnal diffusivity during research cruises - in high horizontal resolution and without extra ship time needed. This contribution relates acoustic data from two cruises in the Tropical North East Atlantic Oxygen Minimum Zone to simultaneous field observations of diapycnal diffusivity: pointwise measurements by a microstructure profiler as well as one integrative value from a large scale Tracer Release Experiment

The impact of product designations on innovation : the case of breweries in the United Kingdom

The European Union has a number of interventions which are designed to encourage diverse agricultural production, to protect product names from misuse and imitation, and to help consumers by giving them information concerning the specific character of the products. The three schemes, collectively known as Protected Geographical Status (PGS) are Protected Designation of Origin (PDO), Protected Geographical Indication (PGI), and Traditional Speciality Guaranteed (TSG). [...] However, there has been limited analysis as to the possible impact of such interventions on the ability of enterprises to enhance their competitiveness through investment in innovation. The aim of the present work is to gain a better understanding of the impact of such policies on the types and levels of innovative activity in firms using PGS schemes

Socio-economic assessment of two small-scale irrigation schemes in Adami Tullu Jido Kombolcha Woreda, Central Rift Valley of Ethiopia

The sustainability of irrigated agriculture is questioned and the challenge is to increase simultaneously land and water productivity in the face of the limited availability of land and water in the CRV, the Central Rift Valley. The aim of this research is to assess the social-economic performance of two communitybased small-scale irrigation schemes in Adami Tullu Jido Kombolcha Woreda (ATJK) and to identify options to improve irrigation performance and resource managemen

3D modelling of geological and anthropogenic deposits at the World Heritage Site of Bryggen in Bergen, Norway

The landscape of many historic cities and the character of their shallow subsurface environments are defined by a legacy of interaction between anthropogenic and geological processes. Anthropogenic deposits and excavations result from processes ranging from archaeological activities to modern urban development. Hence, in heritage cities, any geological investigation should acknowledge the role of past and ongoing human activities, while any archaeological investigation should be conducted with geological processes in mind. In this paper it is shown that 3D geological and anthropogenic models at different scales can provide a holistic system for the management of the subsurface. It provides a framework for the integration of other spatial and processmodels to help assess the preservationpotential for buried heritage. Such an integrated framework model is thus contributing to a decision support system for sustainable urban (re)development and regeneration in cities, while preserving cultural heritage. A collaborative approach is proposed to enhance research and implementation of combined geological and archaeological modelling for sustainable land use planning and heritage preservation, using York and Bryggen as prime examples. This paper presents the status of 3D framework modelling at Bryggen in Norway as an example

Strategic Research Agenda for organic food and farming

The TP Organics Strategic Research Agenda (SRA) was finalised in December 2009. The purpose of the Strategic Research Agenda (SRA) is to enable research, development and knowledge transfer that will deliver relevant outcomes – results that will contribute to the improvement of the organic sector and other low external input systems. The document has been developed through a dynamic consultative process that ran from 2008 to 2009. It involved a wide range of stakeholders who enthusiastically joined the effort to define organic research priorities. From December 2008 to February; the expert groups elaborated the first draft. The consultative process involved the active participation of many different countries. Consultation involved researchers, advisors, members of inspection/certification bodies, as well as different users/beneficiaries of the research such as farmers, processors, market actors and members of civil society organisations throughout Europe and further afield in order to gather the research needs of the whole organic sector

Interface between pest risk science and policy : the EPPO perspective

The European and Mediterranean Plant Protection Organisation (EPPO) is an intergovernmental organization responsible for cooperation in plant protection in the European and Mediterranean region. It provides global distribution maps of pests, and intends to identify the areas at risk from new and emerging pests, in the framework of Pest Risk Analyses. EPPO has developed a decision-support scheme for Pest Risk Analysis (DSS) and a computer program (CAPRA) to assist pest risk analysts in running the decisionsupport scheme. Dedicated rating guidance and a Climatic Suitability Risk Mapping Decision-Support Scheme have recently been developed to guide assessors in identifying the potential area of establishment of a pest. All these tools have been developed taking into account both pest risk science available and needs of policy makers. The use of these tools and of mapping software are undertaken within the framework of EPPO Pest Risk Analyses, as illustrated through the examples of Thaumatotibia leucotreta (Lepidoptera) and Apriona germari (Coleoptera)

The Social Dimension in Selected Candidate Countries in the Balkans: Country Report on Turkey. ENEPRI Research Reports No. 41, 14 December 2007

The European Commission awarded a contract in November 2005 to a consortium composed of the TARKI Social Research Institute (Hungary), CASE, Center for Social and Economic Research (Poland) and CEPS to analyse the socio-economic developments and the process of structural reforms in what were then four candidate countries: Bulgaria, Croatia, Romania and Turkey. The objective was to identify the major challenges in the current demographic, social and economic context that could be considered relevant in determining the capacity of these countries to function in the European Union. This study presents the findings for Turkey and consists of an analytical section and a statistical annex. The other country reports and synthesis report are published separately in this same serie

Big Cities. Big Water. Big Challenges: Water in an Urbanizing World.

This paper applies the water footprint methodology to six megacities across Africa, Asia, and Latin America to explore the effect of urbanization on water use and demand and determine what measures need to be taken to meet this demand. Key threats to water resources in many or all of the cities studied include: water stress or scarcity, pollution and decreasing water quality, and vulnerability to extreme weather caused by climate change
