A survey exploring private farm advisor perspectives of agri-environment schemes : The case of England's Environmental Stewardship programme

Most stakeholder-based research concerning agri-environmental schemes (AES) derives from work engaging with farmers and land managers. Consequently, the voices and opinions of other actors involved in AES tends to be unrepresented in the wider literature. One group of actors that seem particularly overlooked in this respect are private (independent) farm advisors (i.e., the consultants contracted by farmers and land managers to advise-on AES and agronomic matters). To begin to rectify this knowledge gap we developed an exploratory online survey to explore private farm advisor perspectives in the UK; specifically, the situation in England and advisors' experience of Natural England's Environmental Stewardship programme. A total of 251 Natural England registered farm advisors (29.9%) completed our survey. The majority of these had knowledge and expertise in relation to two (31.5%) or three (42.2%) Environmental Stewardship schemes, with proficiency in ELS (93.4%) and HLS (82.8%) being the most common. On average, advisors had 9.6 ± 5.6 yrs of experience and operated (75.3%) in a single region of England. Although our results concentrated upon a relatively simple set of initial topics of inquiry, the survey revealed a number of interesting findings. Firstly; for example, that in the opinion of the advisors working with farmers applying for Environmental Stewardship schemes, the 'knowledge-exchange encounter' occurring between themselves, their clients and Natural England is fundamental to the environmental effectiveness of these schemes as well as their farm business compatibility. Secondly, respondents suggested that beneath this 'encounter' lie tensions arising from the competing agendas and objectives of the different actors involved which can affect the content of agreements; for instance, farmer selection of management options versus Natural England's target environmental objectives. Farm advisors suggested that they had to negotiate this balance whilst also serving the needs of their clients. Thirdly, respondents raised issues concerning the complicated nature of scheme arrangements, both from their own and farmers' perspectives, as well as the adequacy of payments to cover input costs and matters regarding contractual compliance, all of which theyproposed affected farmer participation. Looking ahead, we believe that future AES should account for all of these issues in their design to aid long-term farmer participation, effective agreement implementation and beneficial environmental management

A method to determine the displacement velocity field in the apical region of the Arabidopsis root

In angiosperms, growth of the root apex is determined by the quiescent centre. All tissues of the root proper and the root cap are derived from initial cells that surround this zone. The diversity of cell lineages originated from these initials suggests an interesting variation of the displacement velocity within the root apex. However, little is known about this variation, especially in the most apical region including the root cap. This paper shows a method of determination of velocity field for this region taking the Arabidopsis root apex as example. Assuming the symplastic growth without a rotation around the root axis, the method combines mathematical modelling and two types of empirical data: the published velocity profile along the root axis above the quiescent centre, and dimensions of cell packet originated from the initials of epidermis and lateral root cap. The velocities, calculated for points of the axial section, vary in length and direction. Their length increases with distance from the quiescent centre, in the root cap at least twice slower than in the root proper, if points at similar distance from the quiescent centre are compared. The vector orientation depends on the position of a calculation point, the widest range of angular changes, reaching almost 90°, in the lateral root cap. It is demonstrated how the velocity field is related to both distribution of growth rates and growth-resulted deformation of the cell wall system. Also changes in the field due to cell pattern asymmetry and differences in slope of the velocity profile are modelled.

Valuing beyond economics : a pluralistic evaluation framework for participatory policymaking

The sustainability challenges facing societies call for policies and governance systems that are attuned to the diversity of goods that support and enrich human life via ecological, technical and other kinds of systems, and to the plurality of values that people hold across diverse cultures and belief systems. A pluralistic evaluation framework (PEF) is here presented as a tool for considering diverse kinds of goodness as perceived by diverse stakeholders in the design and evaluation of policies or projects. It arises from considering a suite of aspects of meaning (biotic, economic, aesthetic, etc.) at each of three stages, namely: identifying relevant stakeholders, mapping real-world systems and assessing modes of valuing. This framework, drawing on the philosophical work of Herman Dooyeweerd and Dirk Vollenhoven, offers a joined-up, participatory approach to policymaking. We report pilot trials of the PEF with groups of policymakers at a series of workshops, demonstrating that it provides additional perspectives and unification of core issues and can be used in a wide range of areas of policymaking and project assessment. We also illustrate its potential application to a controversial environmental project and outline how a pluralistic evaluation framework can be used in tandem with existing frameworks

Why nature matters: A systematic review of intrinsic, instrumental, and relational values

\ua9 2023 The Author(s). Published by Oxford University Press on behalf of the American Institute of Biological Sciences. In this article, we present results from a literature review of intrinsic, instrumental, and relational values of nature conducted for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, as part of the Methodological Assessment of the Diverse Values and Valuations of Nature. We identify the most frequently recurring meanings in the heterogeneous use of different value types and their association with worldviews and other key concepts. From frequent uses, we determine a core meaning for each value type, which is sufficiently inclusive to serve as an umbrella over different understandings in the literature and specific enough to help highlight its difference from the other types of values. Finally, we discuss convergences, overlapping areas, and fuzzy boundaries between different value types to facilitate dialogue, reduce misunderstandings, and improve the methods for valuation of nature\u27s contributions to people, including ecosystem services, to inform policy and direct future research

Population Genomics and Phylogeography of an Australian Dairy Factory Derived Lytic Bacteriophage

In this study, we present the full genomic sequences and evolutionary analyses of a serially sampled population of 28 Lactococcus lactis–infecting phage belonging to the 936-like group in Australia. Genome sizes were consistent with previously available genomes ranging in length from 30.9 to 32.1 Kbp and consisted of 55–65 open reading frames. We analyzed their genetic diversity and found that regions of high diversity are correlated with high recombination rate regions (P value = 0.01). Phylogenetic inference showed two major clades that correlate well with known host range. Using the extended Bayesian Skyline model, we found that population size has remained mostly constant through time. Moreover, the dispersion pattern of these genomes is in agreement with human-driven dispersion as suggested by phylogeographic analysis. In addition, selection analysis found evidence of positive selection on codon positions of the Receptor Binding Protein (RBP). Likewise, positively selected sites in the RBP were located within the neck and head region in the crystal structure, both known determinants of host range. Our study demonstrates the utility of phylogenetic methods applied to whole genome data collected from populations of phage for providing insights into applied microbiology

Rays, intrusive growth, and storied cambium in the inflorescence stems of Arabidopsis thaliana (L.) Heynh

Arabidopsis thaliana is a model plant used in analysis of different aspects of plant growth and development. Under suitable conditions, secondary growth takes place in the hypocotyl of Arabidopsis plants, a finding which helps in understanding many aspects of xylogenesis. However, not all developmental processes of secondary tissue can be studied here, as no secondary rays and intrusive growth have been detected in hypocotyl. However, results presented here concerning the secondary growth in inflorescence stems of Arabidopsis shows that both secondary rays and intrusive growth of cambial cells can be detected, and that, in the interfascicular regions, a storied cambium can be developed
