Addressing the Food Loss and Waste Challenge – a WRAP perspective
Unsustainable production and consumption of food constitutes one of the biggest environmental threats to our planet. Eliminating food loss and waste to the largest extent possible – at all stages from producer to final consumer – stands out as an urgent and indispensable step towards more sustainable food systems. In fact, recent research shows that tackling food waste is the third most effective intervention to reduce greenhouse gas emissions, the most important priority of our time (Hawken 2017). The United Nations Sustainable Development Goal (SDG) 12.3 sets out a specific target on food waste to halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses, by 2030. In order to measure global progress towards SDG 12.3, two indices have been proposed: the Food Waste Index (Global Innovation Exchange 2018) and the Food Loss Index (Fabi and English 2018). Successfully achieving SDG 12.3 requires new thinking, new partnerships and new actions to reduce resource use, and increase the efficiency of the production, preservation, processing and distribution of food at the producer, intermediary, processor and wholesale level. It needs wider education, increased awareness, and behavioural change among citizens, retailers, and policy makers across the globe. The goal is to produce more food to feed the world’s expanding population, while reducing land use, fertilizer applications and critically dramatically reducing greenhouse gas emissions (Flanagan et al. 2019). To help deliver this critical target, Champions 12.3 has been formed (Champions 12.3 2016). It is a unique coalition of executives from governments, businesses, international organizations, research institutions, and civil society dedicated to inspiring ambition, mobilizing action, and accelerating progress toward achieving SDG Target 12.3. It has produced a trajectory for delivering 12.3, what needs to happen and by when that provides the critical “roadmap for change” (Champions 12.3 2017a). In this paper we provide the perspective of WRAP (the Waste and Resources Action Programme) on the economic, social and environmental case for action, what research shows works in driving change and how these activities might be scaled to deliver SDG 12.3. WRAP is a not for profit organization, based in the UK and working in more than 20 countries worldwide, that aims to help people and planet thrive. WRAP is a leader in tackling food loss and waste effectively and supporting international food loss and waste prevention projects – including Champions 12.3. Since 2007, WRAP has been a partner in many global food loss and waste projects and initiatives and has co-authored key reports. This includes EU projects such as FUSIONS (2016) and REFRESH (2020a), as well as the development of the Food Loss and Waste Accounting and Reporting Standard (World Resources Institute 2016). In the UK, WRAP, food businesses and other partners have delivered large-scale interventions to reduce food waste across supply chains, and households for more than ten years (since 2007), supported by UK Governments and by businesses and enabled by a series of collaborative public-private partnerships. WRAP’s work in the UK with its partners has helped reduce food by 27% or 1.7 Mt/y saving food worth £5 billion/ year. Cumulatively the total food waste reduction has been 18.5 Mt worth US$50 billion (WRAP 2020a). This paper highlights the importance of tackling food loss and waste, using specific recent examples from the UK and Mexico. Second, we discuss the business case for addressing food loss and waste. Thirdly we highlighting two approaches that research shows can be particularly effective at driving change at scale, and we conclude by proposing a three-point plan for tackling food waste to deliver SDG 12.3 over the next 10 years

Addressing Food Loss and Waste : A Global Problem with Local Solutions
The report focuses on the role that food loss and waste (FLW) could play in reducing the environmental footprint of food systems while attempting to meet the caloric and nutrient needs of a population expected to increase by 3 billion people in the next 30 years. The performance of the global food system over the last century has been extraordinary. From a global population of 1.6 billion people in 1900 to nearly 8 billion in 2020, the agri-food sector has risen to the challenge of providing global caloric sufficiency, mainly by increasing yields of a few principal staple crops. However, this path is no longer sustainable
Prevalence of Borderline Personality Disorder in University Samples: Systematic Review, Meta-Analysis and Meta-Regression.
OBJECTIVE: To determine pooled prevalence of clinically significant traits or features of Borderline Personality Disorder among college students, and explore the influence of methodological factors on reported prevalence figures, and temporal trends. DATA SOURCES: Electronic databases (1994-2014: AMED; Biological Abstracts; Embase; MEDLINE; PsycARTICLES; CINAHL Plus; Current Contents Connect; EBM Reviews; Google Scholar; Ovid Medline; Proquest central; PsychINFO; PubMed; Scopus; Taylor & Francis; Web of Science (1998-2014), and hand searches. STUDY SELECTION: Forty-three college-based studies reporting estimates of clinically significant BPD symptoms were identified (5.7% of original search). DATA EXTRACTION: One author (RM) extracted clinically relevant BPD prevalence estimates, year of publication, demographic variables, and method from each publication or through correspondence with the authors. RESULTS: The prevalence of BPD in college samples ranged from 0.5% to 32.1%, with lifetime prevalence of 9.7% (95% CI, 7.7-12.0; p < .005). Methodological factors contributing considerable between-study heterogeneity in univariate meta-analyses were participant anonymity, incentive type, research focus and participant type. Study and sample characteristics related to between study heterogeneity were sample size, and self-identifying as Asian or "other" race. The prevalence of BPD varied over time: 7.8% (95% CI 4.2-13.9) between 1994 and 2000; 6.5% (95% CI 4.0-10.5) during 2001 to 2007; and 11.6% (95% CI 8.8-15.1) from 2008 to 2014, yet was not a source of heterogeneity (p = .09). CONCLUSIONS: BPD prevalence estimates are influenced by the methodological or study sample factors measured. There is a need for consistency in measurement across studies to increase reliability in establishing the scope and characteristics of those with BPD engaged in tertiary study
Methodological issues associated with collecting sensitive information over the telephone - experience from an Australian non-suicidal self-injury (NSSI) prevalence study
<p>Abstract</p> <p>Background</p> <p>Collecting population data on sensitive issues such as non-suicidal self-injury (NSSI) is problematic. Case note audits or hospital/clinic based presentations only record severe cases and do not distinguish between suicidal and non-suicidal intent. Community surveys have largely been limited to school and university students, resulting in little much needed population-based data on NSSI. Collecting these data via a large scale population survey presents challenges to survey methodologists. This paper addresses the methodological issues associated with collecting this type of data via CATI.</p> <p>Methods</p> <p>An Australia-wide population survey was funded by the Australian Government to determine prevalence estimates of NSSI and associations, predictors, relationships to suicide attempts and suicide ideation, and outcomes. Computer assisted telephone interviewing (CATI) on a random sample of the Australian population aged 10+ years of age from randomly selected households, was undertaken.</p> <p>Results</p> <p>Overall, from 31,216 eligible households, 12,006 interviews were undertaken (response rate 38.5%). The 4-week prevalence of NSSI was 1.1% (95% ci 0.9-1.3%) and lifetime prevalence was 8.1% (95% ci 7.6-8.6).</p> <p>Methodological concerns and challenges in regard to collection of these data included extensive interviewer training and post interview counselling. Ethical considerations, especially with children as young as 10 years of age being asked sensitive questions, were addressed prior to data collection. The solution required a large amount of information to be sent to each selected household prior to the telephone interview which contributed to a lower than expected response rate. Non-coverage error caused by the population of interest being highly mobile, homeless or institutionalised was also a suspected issue in this low prevalence condition. In many circumstances the numbers missing from the sampling frame are small enough to not cause worry, especially when compared with the population as a whole, but within the population of interest to us, we believe that the most likely direction of bias is towards an underestimation of our prevalence estimates.</p> <p>Conclusion</p> <p>Collecting valid and reliable data is a paramount concern of health researchers and survey research methodologists. The challenge is to design cost-effective studies especially those associated with low-prevalence issues, and to balance time and convenience against validity, reliability, sampling, coverage, non-response and measurement error issues.</p
Exploring the relationship between experiential avoidance, coping functions and the recency and frequency of self-harm
This study investigated the relationship between experiential avoidance, coping and the recency and frequency of self-harm, in a community sample (N = 1332, aged 16–69 years). Participants completed online, self-report measures assessing self-harm, momentary affect, experiential avoidance and coping in response to a recent stressor. Participants who had self-harmed reported significantly higher levels of experiential avoidance and avoidance coping, as well as lower levels of approach, reappraisal and emotional regulation coping, than those with no self-harm history. Moreover, more recent self-harm was associated with lower endorsement of approach, reappraisal and emotion regulation coping, and also higher levels of both avoidance coping and experiential avoidance. Higher experiential avoidance and avoidance coping also predicted increased lifetime frequency of self-harm. Conversely, increased approach and reappraisal coping were associated with a decreased likelihood of high frequency self-harm. Although some of the effects were small, particularly in relation to lifetime frequency of self-harm, overall our results suggest that experiential avoidance tendency may be an important psychological factor underpinning self-harm, regardless of suicidal intent (e.g. including mixed intent, suicidal intent, ambivalence), which is not accounted for in existing models of self-harm
Suicidality among adolescents engaging in nonsuicidal self-injury (NSSI) and firesetting: The role of psychosocial characteristics and reasons for living
Background: Co-occurrence of problem behaviors, particularly across internalizing and externalizing spectra, increases the risk of suicidality (i.e., suicidal ideation and attempt) among youth. Methods: We examined differences in psychosocial risk factors across levels of suicidality in a sample of 77 school-based adolescents engaging in both nonsuicidal self-injury (NSSI) and repeated firesetting. Participants completed questionnaires assessing engagement in problem behaviors, mental health difficulties, negative life events, poor coping, impulsivity, and suicidality. Results: Adolescents endorsing suicidal ideation reported greater psychological distress, physical and sexual abuse, and less problem solving/goal pursuit than those with no history of suicidality; adolescents who had attempted suicide reported more severe NSSI, higher rates of victimization and exposure to suicide, relative to those with suicidal ideation but no history of attempt. Additional analyses suggested the importance of coping beliefs in protecting against suicidality. Conclusions: Clinical implications and suggestions for future research relating to suicide prevention are discussed
Monitoring of microbial hydrocarbon remediation in the soil
Bioremediation of hydrocarbon pollutants is advantageous owing to the cost-effectiveness of the technology and the ubiquity of hydrocarbon-degrading microorganisms in the soil. Soil microbial diversity is affected by hydrocarbon perturbation, thus selective enrichment of hydrocarbon utilizers occurs. Hydrocarbons interact with the soil matrix and soil microorganisms determining the fate of the contaminants relative to their chemical nature and microbial degradative capabilities, respectively. Provided the polluted soil has requisite values for environmental factors that influence microbial activities and there are no inhibitors of microbial metabolism, there is a good chance that there will be a viable and active population of hydrocarbon-utilizing microorganisms in the soil. Microbial methods for monitoring bioremediation of hydrocarbons include chemical, biochemical and microbiological molecular indices that measure rates of microbial activities to show that in the end the target goal of pollutant reduction to a safe and permissible level has been achieved. Enumeration and characterization of hydrocarbon degraders, use of micro titer plate-based most probable number technique, community level physiological profiling, phospholipid fatty acid analysis, 16S rRNA- and other nucleic acid-based molecular fingerprinting techniques, metagenomics, microarray analysis, respirometry and gas chromatography are some of the methods employed in bio-monitoring of hydrocarbon remediation as presented in this review
