Review: Consumption-stage food waste reduction interventions - What works and how to design better interventions

Food waste prevention has become an issue of international concern, with Sustainable Development Goal 12.3 aiming to halve per capita global food waste at the retail and consumer levels by 2030. However there is no review that has considered the effectiveness of interventions aimed at preventing food waste in the consumption stages of the food system. This significant gap, if filled, could help support those working to reduce food waste in the developed world, providing knowledge of what interventions are specifically effective at preventing food waste. This paper fills this gap, identifying and summarizing food-waste prevention interventions at the consumption/consumer stage of the supply chain via a rapid review of global academic literature from 2006 to 2017. We identify 17 applied interventions that claim to have achieved food waste reductions. Of these, 13 quantified food waste reductions. Interventions that changed the size or type of plates were shown to be effective (up to 57% food waste reduction) in hospitality environments. Changing nutritional guidelines in schools were reported to reduce vegetable waste by up to 28%, indicating that healthy diets can be part of food waste reduction strategies. Information campaigns were also shown to be effective with up to 28% food waste reduction in a small sample size intervention. Cooking classes, fridge cameras, food sharing apps, advertising and information sharing were all reported as being effective but with little or no robust evidence provided. This is worrying as all these methods are now being proposed as approaches to reduce food waste and, except for a few studies, there is no reproducible quantified evidence to assure credibility or success. To strengthen current results, a greater number of longitudinal and larger sample size intervention studies are required. To inform future intervention studies, this paper proposes a standardised guideline, which consists of: (1) intervention design; (2) monitoring and measurement; (3) moderation and mediation; (4) reporting; (5) systemic effects. Given the importance of food-waste reduction, the findings of this review highlight a significant evidence gap, meaning that it is difficult to make evidence-based decisions to prevent or reduce consumption-stage food waste in a cost-effective manner

Energy policy under austerity localism: what role for local authorities?

In the UK, local authorities (LAs) have been placed at the forefront of domestic energy-reduction strategies as the responsible actors for coordinating policy in this sector. Yet, there has been little research regarding the role of LAs in this policy agenda, and their abilities to bring together stakeholders in the successful design and implementation of strategies to reduce energy demands. The paper aims to fill this gap by highlighting the relevance and importance of the energy policy sphere to local government studies, building on the idea of resilient LAs within the context of tensions between the localism agenda and the actual implementation of energy efficiency polices. This is achieved through multiple rounds of semi-structured interviews with LA officers. Our findings reveal that LAs, operating under a localism agenda, lack the freedoms and resources from central government to meet the needs of multiple stakeholders, resorting to short-term policies

Biased decision making in realistic extra-procedural nuclear control room scenarios

In normal operations and emergency situations, operators of nuclear control rooms rely on procedures to guide their decision making. However, in emergency situations, where several interacting problems can cause unpredictable adverse effects, these procedures may be insufficient in guiding operators to safe shutdown of the power plant. Little is known about the decision making strategies that operators employ in these extra-procedural situations. To address this, a realistic simulation study was conducted with five crews of active, licensed nuclear operators to see the behavioural patterns that occur when procedures are not sufficient. This paper, a re-analysis of a dataset collected for a different study, investigates how the design and existence of procedures influence, and possibly bias, decision making strategies. We found evidence that operators were affected by confirmation bias, and that, in some cases, the mismatch between their home power plant and the simulated power plant made them commit errors due to misapplied expertise. We further found that this effect was amplified by the existence and design of the procedures used. Based on these findings, we suggest that designers may improve safety by creating procedures that bear the risks of these biases in mind, or by specifically aiming to debias the users. Avenues for debiasing through design are discussed

Resource Protection: a Model For National Parks

As development of lands around national parks increases it will be important for land use controls to be in place to protect park resources. This study resulted in the development of a model that can be used to refine a protection plan for park resources using a geographic information system. This model considers existing land use regulations, public perception, and the unique physical characteristics of a national park. Cartographic modeling is used to apply unique park variables to create an individualized resource protection plan. Wilson\u27s Creek National Battlefield in Southwest Missouri and the adjacent area is used to test the effectiveness of this model. One of the important resources at this park are scenic vistas from three viewpoints within the park. This study resulted in a set of policy recommendations to preserve the viewshed of these three points. Additionally, guidelines were developed that other national park managers can use when constructing a resource protection plan designed specifically to protect their park\u27s unique resources
