In the last decade, in many European Countries more and more measures have been initiated aiming at the prevention of food losses and wastes along the entire value chain. In order to evaluate or monitor such important measures it is crucial to obtain quantitative information on generated food waste amounts, subsequently enabling the quantitative evaluation of the measure’s outcomes and efficiency. Currently there is a paucity of quantitative information, particularly on food losses that are directly generated during harvesting processes. Up to date, no method is available or standardised aiming at the in-situ or on-site quantification of food losses during harvest. Using the example of the potato harvest, this study presents a practical approach for determining potato losses. To test the applicability of the developed method, on-site measurements were conducted directly on the field at five different locations in Austria and Germany. Our method enables the quantification of food losses based on defined areas along the harvested potato rows, where the analyser manually collects potatoes during their harvest. Hereby, two types of potato losses needs to be considered: non-harvested, under-sized potatoes that remain under the earth and the harvested ones, which are rejected on-site because of quality requirements regarding their size, shape, and state of health. Our study shows that between 1 and 9% of field losses (based on yield potential) can be generated during the potato harvest. In future, this method may be the basis for standardised protocols in order to be able to derive cultivar-specific benchmarks and, consequently, to develop measures for preventing food losses. In general, more case studies and evidence-based ground-up measurements on other cultivars and for other regions are needed focusing on the on-site quantification of post-harvest losses.
As a salutogenic concept, “consumption corridors” aims to support what is necessary for sustainable wellbeing to be achieved in relation to the Earth system, with a deep consideration for justice and equity. Living in consumption corridors is a representation of everyday life whereby people live within limits, so that all people – now and in the future – can access what is needed to live a good life. In this special issue, a series of scholars and practitioners have come together to further develop the concept, engage with its ethodological implications, and relate it to consumption domains and policy implications. We begin by introducing how the concept emerged, in relation to the complexity of grappling with the societal transformations required for achieving more sustainable forms of consumption. We then present the different contributions, which demonstrate the importance of considering both maximum and minimum consumption standards, the relevance of human-need theories, as well as the difference between achieving wellbeing and the means necessary for doing so. We conclude by opening up to areas that merit further deliberation: how to relate consumption corridors to everyday-life dynamics, but also to the critical question of power relations at play in implementing consumption corridors.
Social Sustainability through Social Interaction—A National Survey on Community Gardens in Germany
(2018)
Contemporary food production and consumption cannot be regarded as sustainable and raises problems with its wide scope involving diverse actors. Moreover, in the face of demographic change and a growing global population, sus-tainability problems arising from food systems will likely become more serious in the future. For example, agricultural production must deal with the impacts of climate change, increasingly challenging land-use conflicts, and rising health and social costs on both individual and societal levels. The unsustainability of current arrangements arises from the industrialization and globalization of agriculture and food processing, the shift of consumption patterns toward more dietary animal protein, the emergence of modern food styles that entail heavily processed products, the growing gap on a global scale between rich and poor, and the paradoxical lack of food security amid an abundance of food. These factors are attributable to national and international policies and regulations, as well as to prevalent business prac-tices and, in particular, consumers’ values and habits. The most effective ways for affluent societies to reduce the environmental impact of their diets are to reduce consumption of meat and dairy products (especially beef), to favor organic fruits and vegetables, and to avoid goods that have been transported by air on both individual and institu-tional levels (e.g., public procurement, public catering). In examining the unsustainability of the current food system this article reviews the pertinent literature to derive a working definition of sustainable food consumption, outlines the major issues and impacts of current food-consumption practices, and discusses various policy interventions, including information-based instruments, market-based initiatives, direct regulations, and “nudges.” It concludes with a call for integrative, cross-sectoral, and population-wide policies that address the full range of drivers of unsustainable food production and consumption.

Abstract In sub-Sahara Africa, micronutrient deficiency, especially of antioxidant micronutrients including vitamins A, C, and E, beta-carotene, selenium, zinc, and polyphenols is very common in HIV-positive patients. Amongst adults, women are the most vulnerable. Antioxidants are known to play a vital role in the immune system, reducing oxidative stress. Oxidative stress is induced by excess production of reactive oxygen species (ROS), due to the HIV infection. Such damage may be prevented or moderated through adequate oral intake of antioxidants, scavenging ROS, as well as protecting cells and tissues against oxidative stress. Antioxidants can be provided to the body through locally available antioxidant rich-diets such as fruit-and-vegetable-based diets and/or dietary supplements. Provision of antioxidants through local diets or dietary supplements exercise beneficial effects on biological markers of the immune system (CD4 and viral load). However, while dietary supplements represent a costly and short-term strategy to limiting antioxidant deficiency, local diets, combined with adequate nutritional education, can provide a low-cost and long-term strategy to reduce oxidative stress, prevent micronutrient deficiency, and slow down HIV disease progression. The former can be applicable in countries around the West, Central, and South coast of Africa, which are rich in natural food resources. In contrast with significant evidence that dietary supplements confer benefits in HIV patients, fewer data are available relating to the benefits of local diets. Thus the need to do more research in this area arises. This review compares available data on effects of antioxidants on CD4 and viral load in HIV-positive women noneligible for antiretroviral therapy. Intake of antioxidants though dietary supplements and local diet, associated with nutritional education, is compared. Studies conducted in sub-Sahara Africa are considered.
Um die Außer-Haus-Verpflegung auf Quartiersebene nachhaltiger zu gestalten, greift das vorliegende Paper auf das Good Practice Beispiel des Ökodorfs Sieben Linden zurück. Dessen Verpflegungskonzept wird insbesondere unter dem Ge-sichtspunkt sozialer Praktiken untersucht. Trotz struktureller Unterschiede lassen sich einige der im Ökodorf angewandten sozialen Praktiken – teils in angepasster Form – auf die Entwicklung eines Mittagstisches im Quartier übertragen. Wie im Ökodorf können auch im Quartier zahlreich „Interlocking-Effekte“ durch einen ge-meinsam organisierten, nachhaltigen Mittagstisch entstehen.
Is German family firm performance affected by CEO and TMT behavior and emotional intelligence?
(2019)
Family firm performance through transformational CEO leadership and familiness-related team forces
(2024)
Purpose. The purpose of this study is to test the role of familiness-related team forces induced by the CEO of family firms. In particular, we report on the effects of the transformational leadership style of CEOs on their respective top-management team (TMT) and firm performance when viewed through a familiness lens.
Design/methodology/approach. Survey measures were taken from a snowballed
sample of 72 CEOs of German family firms as well as from 245 members of their TMTs. We tested the aggregated firm-level data with objective performance indicators of the firms they led.
Findings. Support was obtained for the three hypothesized team-force mediations and the four-path mediation model. The relationship between CEO’s transformational style and
high family-firm performance is found to be serially mediated by TMT cohesion, behavioral integration and efficacy. Together, these three types of collective forces are assumed to be the
familiness effect of a family-member CEO with a transformational leadership style.
Originality. With our model we quantitatively tested familiness-type forces vis-à-vis firm performance. Theoretical and practical implications of these findings are discussed.
Purpose. Several studies of family firm failures have pointed to non-family members in leading positions as a reason. However, non-family members have often played a key role in family-firm longevity, while non-family executives’ involvement in family firms is increasing. These non-family executives who (co-)run family firms are thought to require an almost impossible set of behavioural qualities. The aim of this exploratory study is to find out how specific leader behaviours of effective family executives and non-family executives may differ.
Design/methodology/approach.
Based on Dulewicz and Higgs’ (2005) broad leadership frame, the authors draw attention to a large range of behaviours of family-firm executives. In-depth interviews were conducted with successful German executives, both family and non-family ones. Their answers had to contain specific behavioural examples.
Findings. More behavioural similarities than differences are shown between family- and non-family-based executives. Yet, the self-reflective communicative behavioural qualities of the non-family executives could balance a lack of such qualities among the family-based executives. Based on the three major differences – decision-making style, communication versatility and self-awareness – specific new research propositions are distilled about effective family firm leadership.
Originality/value. Practical suggestions for recruiting non-family executives are offered. Future quantitative longitudinal research on how to pair specific behavioural qualities of family and non-family based executives that optimise family-firm longevity is urgently needed.
Familiness is considered one of the most valuable assets of family firms. But how familiness-related forces at the top management level of family firms may work their way into positive firm performance has not been addressed empirically before. The present field study couples upper-echelon theory with team-leadership theory and examines the effects of the transformational leadership style (TFL) of family- based CEOs in top management team (TMT) processes and on firm performance. Survey measures were gathered from 72 CEOs of German family firms as well as from 245 members of their TMTs. We tested the aggregated firm-level data, including objective firm-performance indicators of the 72 German family firms they led. Support was obtained for a four-path mediation model, in which three distinct familiness-related team forces (TMT cohesion, behavioral integration, and efficacy) serve as mediators between CEO TFL and family-firm performance in a series. With our model we focus on the under- researched area of familiness vis-à-vis family-firm performance. Theoretical and practical implications of the findings are discussed, and suggestions are offered for new avenues of family-firm familiness inquiry.
Emotionally intelligent top management and high family firm performance: Evidence from Germany
(2022)
Executives in family firms are often confronted with emotionally loaded issues, in part due to the need to include the interests of the owning family. Given this context, we hypothesize how high family-firm performance is affected by the emotional intelligence (EI) of a family-based CEO and top-management team (TMT), in addition to the CEO's transformational leadership (TFL) and TMT's behavioral integration. Survey measures were taken from a random sample of 72 CEOs of German family firms and 245 members of their TMTs. We found that TMT behavioral integration mediates between CEO TFL and objective firm performance while CEO EI is significantly related to both CEO TFL and TMT EI. Implications are discussed for future research thereby suggesting an extension to upper-echelon theory.
