Systems thinking, interdisciplinarity and farmer participation: essential ingredients in working for more sustainable organic farming systems

This report was presented at the UK Organic Research 2002 Conference. This paper discusses the principles and values behind some of the innovative agricultural research methods which have evolved over the past 30 years in many countries and suggests that the lessons from this experience could have significant benefits in the development of organic research in the UK. The author argues that the key elements which need to be incorporated into a new approach to research on organic systems are:- systemic thinking (the need for a more holistic understanding of the context of farming and rural livelihoods), interdisciplinarity, (contributions from both social and natural science in the research process) and farmer-participation (the active participation and partnership of farmers and other key stakeholders in the process of design, planning, implementing, monitoring and evaluating research). By incorporating these principles, both into the vision of what research can become within in the organic movement, and into the methodologies that are used in new research partnerships, it is suggested that we could learn our way towards more sustainable, organically-based rural livelihoods in the future

Organising Collective Action for Effective Environmental Management and Social Learning in Wales

The paper explored key factors that might lead to successful agri-environmental social learning and collective action in order to deliver landscape-scale resource management within agri-environment schemes. Using the theory of collective action as an analytical framework the paper examined findings from in-depth interviews with 20 members of two co-operative initiatives in Wales and two participatory workshops. Consideration of the theory helped in understanding how individuals come together to provide public goods, and the conditions that make this activity a success. Factors of importance for organising and delivering collective agri-environment schemes were: locally adaptable engagement strategies; working with group members previously known to each other; institutional arrangements that limited group size and which allowed groups to develop their own solutions and implementation rules; and external support offering the services of a local facilitator and funding for both planning and management stages. A clear finding from the research was the extent to which both business and social confidence can grow within such groups which opens up further development opportunities. The paper identifies key factors that could be used to encourage and enhance the success of co-operative groups in delivering landscape-scale agri-environment schemes. The research findings identify appropriate mechanisms for the design and delivery of collective agri-environment schemes and environment management in the UK, which can also be applied to other parts of Europe

Organic food and farming research needs in the UK:A report on a stakeholder participatory consultation process

During 2005 Defra commissioned a study to identify and analyse issues and aspirations that organic stakeholders felt should be addressed by publicly funded organic food and farming research in the UK. How this was undertaken is presented in this paper. A series of 12 workshops were undertaken with stakeholders throughout the UK. Nearly 300 stakeholders attended the workshops. These workshops used participatory approaches to identify and record the most important issues and aspirations from those attending. The use of a highly participatory style was greatly appreciated by stakeholders. In most cases the interaction between stakeholders worked well and resulted in lively discussions. The workshops have served to open up a useful dialogue between groups of stakeholders who do not normally communicate directly. They have produced a significant number of interesting and challenging issues and aspirations

Collective Action for Effective Environmental Management and Social Learning in Wales

Increasingly it is recognised that land management at a landscape‐scale can deliver greater public good benefits than at the individual farm scale. Collective agri‐environment schemes are one mechanism for achieving this land management, but such schemes are in the early stages of development in the UK and uncertainty exists as to their appropriate design and delivery. This paper is based on two research projects undertaken in Wales to identify key factors that might lead to successful agri‐environmental co‐operation. The research involved in‐depth analysis of three existing farmer co‐operatives in Wales, including face to face interviews and participatory workshops. Using the theory of collective action as an analytical framework, the paper identifies key factors that could be used to encourage and enhance the success of co‐operative groups in delivering landscape‐scale schemes. Of importance were: locally adaptable engagement strategies; working with group members previously known to each other; institutional arrangements that limited group size and which allowed groups to develop their own solutions and implementation rules; and external support offering the services of a local facilitator and funding for both planning and management stages. A clear finding from the research was the extent to which both business and social confidence can grow within such groups which opens up further development opportunities. Improving the farming community’s capacity to co‐operate will have far‐reaching benefits for all public good provision and diversification activities

Edge local complementation for logical cluster states

A method is presented for the implementation of edge local complementation in graph states, based on the application of two Hadamard operations and a single controlled-phase (CZ) gate. As an application, we demonstrate an efficient scheme to construct a one-dimensional logical cluster state based on the five-qubit quantum error-correcting code, using a sequence of edge local complementations. A single physical CZ operation, together with local operations, is sufficient to create a logical CZ operation between two logical qubits. The same construction can be used to generate any encoded graph state. This approach in concatenation may allow one to create a hierarchical quantum network for quantum information tasks.Comment: 15 pages, two figures, IOP styl

Fatal Exudative Dermatitis (FED) in Island Populations of Red Squirrels (Sciurus vulgaris): Spillover of a Virulent Staphylococcus aureus Clone (ST49) From Reservoir Hosts.

Fatal exudative dermatitis (FED) is a significant cause of death of red squirrels (Sciurus vulgaris) on the island of Jersey in the Channel Islands where it is associated with a virulent clone of Staphylococcus aureus, ST49. S. aureus ST49 has been found in other hosts such as small mammals, pigs and humans, but the dynamics of carriage and disease of this clone, or any other lineage in red squirrels, is currently unknown. We used whole-genome sequencing to characterize 228 isolates from healthy red squirrels on Jersey, the Isle of Arran (Scotland) and Brownsea Island (England), from red squirrels showing signs of FED on Jersey and the Isle of Wight (England) and a small number of isolates from other hosts. S. aureus was frequently carried by red squirrels on the Isle of Arran with strains typically associated with small ruminants predominating. For the Brownsea carriage, S. aureus was less frequent and involved strains associated with birds, small ruminants and humans, while for the Jersey carriage S. aureus was rare but ST49 predominated in diseased squirrels. By combining our data with publicly available sequences, we show that the S. aureus carriage in red squirrels largely reflects frequent but facile acquisitions of strains carried by other hosts sharing their habitat ('spillover'), possibly including, in the case of ST188, humans. Genome-wide association analysis of the ruminant lineage ST133 revealed variants in a small number of mostly bacterial-cell-membrane-associated genes that were statistically associated with squirrel isolates from the Isle of Arran, raising the possibility of specific adaptation to red squirrels in this lineage. In contrast there is little evidence that ST49 is a common carriage isolate of red squirrels and infection from reservoir hosts such as bank voles or rats, is likely to be driving the emergence of FED in red squirrels

Controlling femtosecond-laser-driven shock-waves in hot, dense plasma

Ultrafast pump-probe reflectometry and Doppler spectrometry of a supercritical density plasma layer excited by 1017-1018 W/cm2 intensity, 30 fs, and 800 nm laser pulses reveal the interplay of laser intensity contrast and inward shock wave strength. The inward shock wave velocity increases with an increase in laser intensity contrast. This trend is supported by simulations as well as by a separate independent experiment employing an external prepulse to control the inward motion of the shock wave. This kind of cost-effective control of shock wave strength using femtosecond pulses could open up new applications in medicine, science, and engineering
