How scalable is sustainable intensification?

Sustainable intensification is a concept of growing importance, yet it is in danger of becoming scientifically obsolete because of the diversity of meanings it has acquired. To avoid this, it is important to consider the various scales on which it can aid progress towards feeding human populations while also protecting our environment

Sustainability and the common good: Catholic Social Teaching and ‘Integral Ecology’ as contributions to a framework of social values for sustainability transitions

It is widely acknowledged that the large-scale and long-term transitions needed to mitigate climate change and to implement policies for sustainable development within planetary boundaries require significant shifts in values and behaviours. Consequently, there is increasing interest in the processes through which major societal transitions for sustainability can occur through peaceful cooperation and widespread embrace of pro-environmental values, and the values associated with the broad concept of sustainability such as care for the interests of future generations and concern for the poor. This encompasses the search for compelling narratives to frame the process and goals of change and the need for the fostering of virtues and ethical frameworks of identity and practice that can underpin advocacy and change for sustainability. This requires drawing on richer sources of values and ethics. We suggest that important resources can be found in religious, as well as secular traditions of social values and ethical analysis. While major religions have begun to reflect environmental concerns and sustainability goals in their theology and praxis, with immense potential and actual influence over value and behaviours, little research has explored the impacts and implications of this development; nor indeed, the intellectual stimulus and social capabilities they can offer to secular thinkers and practitioners in sustainable development. In particular, we argue that there is a need to consider the affinities between secular sustainability frameworks for ethics and policy and the concepts of Catholic Social Teaching (CST) on the Common Good, recently updated by Pope Francis to integrate ecological concern and a call for universal ‘ecological conversion’ and cooperation. We outline the key features of CST and the Pope’s new ‘Integral Ecology’ framework and identify affinities, in particular, with Elinor Ostrom’s system of design principles for sustainable management of commons. We conclude with suggestions for research to investigate the interrelationships of the Integral Ecology reframing of CST with initiatives for transformational change in values and practices for sustainability

Multi-criterion trade-offs and synergies for spatial conservation planning

1. Nature conservation policies need to deliver on multiple criteria, including genetic diversity, population viability and species richness as well as ecosystem services. The challenge of integrating these may be addressed by simulation modelling. 2. We used four models (MetaConnect, SPOMSIM, a community model and InVEST) to assess a variety of spatial habitat patterns with two levels of total habitat cover and realised at two spatial scales, exploring which landscape structures performed best according to five different criteria assessed for four functional types of organisms (approximately representing trees, butterflies, small mammals and birds). 3. The results display both synergies and trade-offs: population size and pollination services generally benefitted more from fragmentation than did genetic heterozygosity, and species richness more than allelic richness, although the latter two varied considerably among the functional types. 4. No single landscape performed best across all criteria, but averaging over criteria and functional types, overall performance improved with greater levels of habitat cover and intermediate fragmentation (or less fragmentation in cases with lower habitat cover). 5. Synthesis and applications. Different conservation objectives must be traded off, and considering only a single taxon or criterion may result in sub-optimal choices when planning reserve networks. Nevertheless, heterogeneous spatial patterns of habitat can provide reasonable compromises for multiple criteria

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

The spatial scale of density-dependent growth and implications for dispersal from nests in juvenile Atlantic salmon

By dispersing from localized aggregations of recruits, individuals may obtain energetic benefits due to reduced experienced density. However, this will depend on the spatial scale over which individuals compete. Here, we quantify this scale for juvenile Atlantic salmon (Salmo salar) following emergence and dispersal from nests. A single nest was placed in each of ten replicate streams during winter, and information on the individual positions (±1 m) and the body sizes of the resulting young-of-the-year (YOY) juveniles was obtained by sampling during the summer. In six of the ten streams, model comparisons suggested that individual body size was most closely related to the density within a mean distance of 11 m (range 2–26 m). A link between body size and density on such a restricted spatial scale suggests that dispersal from nests confers energetic benefits that can counterbalance any survival costs. For the four remaining streams, which had a high abundance of trout and older salmon cohorts, no single spatial scale could best describe the relation between YOY density and body size. Energetic benefits of dispersal associated with reduced local density therefore appear to depend on the abundance of competing cohorts or species, which have spatial distributions that are less predictable in terms of distance from nests. Thus, given a trade-off between costs and benefits associated with dispersal, and variation in benefits among environments, we predict an evolving and/or phenotypically plastic growth rate threshold which determines when an individual decides to disperse from areas of high local density

Global Assessment of Agricultural System Redesign for Sustainable Intensification

The sustainable intensification (SI) of agricultural systems offers synergistic opportunities for the co31 production of agricultural and natural capital outcomes. Efficiency and Substitution are steps towards SI, but system Redesign is essential to deliver optimum outcomes as ecological and economic conditions change. We show global progress towards SI by farms and hectares, using seven SI sub-types: integrated pest management, conservation agriculture, integrated crop and biodiversity, pasture and forage, trees, irrigation management, and small/patch systems. From 47 SI initiatives at scale (each >104 farms or hectares), we estimate 163M farms (29% of all worldwide) have crossed a redesign threshold, practising forms of SI on 453Mha of agricultural land (9% of worldwide total). Key challenges include investing to integrate more forms of SI in farming systems, creating agricultural knowledge economies, and establishing policy measures to scale SI further. We conclude that SI may be approaching a tipping point where it could be transformative

A global experiment on motivating social distancing during the COVID-19 pandemic

Significance Communicating in ways that motivate engagement in social distancing remains a critical global public health priority during the COVID-19 pandemic. This study tested motivational qualities of messages about social distancing (those that promoted choice and agency vs. those that were forceful and shaming) in 25,718 people in 89 countries. The autonomy-supportive message decreased feelings of defying social distancing recommendations relative to the controlling message, and the controlling message increased controlled motivation, a less effective form of motivation, relative to no message. Message type did not impact intentions to socially distance, but people’s existing motivations were related to intentions. Findings were generalizable across a geographically diverse sample and may inform public health communication strategies in this and future global health emergencies. Abstract Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges
