Coping and social cohesion mechanisms in addressing climate change and land degradation in Ghana
(2025) Amankwah, Harry Quaye; Ndah, Hycenth Tim; Schuler, Johannes; Abdulai, Alhassan Lansah; Knierim, Andrea
The West Africa sub-region is faced with major interlinked challenges in ensuring sustainable livelihoods in the context of climate change and land degradation. To ensure sustainable food production and resource use, agriculture needs to be resilient through the application of responsive adaptation and coping strategies. While many studies have explored coping and adaptation strategies employed by farmers, little attention has been paid to the farmers’ indigenous practices and the role of social cohesion mechanisms. Using the sustainable livelihood framework, this study addressed this gap by exploring coping strategies and social cohesion mechanisms used by smallholder farmers in northern Ghana. It made use of a mixed-method approach, including a household survey, focus group discussions, expert interviews, field observations, and key informant interviews. Data was collected from 60 households in 6 communities across 3 districts in the study region. The results showed that social assets such as membership of self-help groups were the most important source of coping, particularly for the most vulnerable households. Such membership enabled farmers to secure micro-loans and receive aid from fellow members during extreme climate events such as floods. Farmers’ tacit knowledge emerged as pivotal in coping with climate change and enhancing soil fertility, encompassing traditional weather forecasting, the making of bio-pesticides, and sustainable land management (SLM) practices such as ridge and bund creation as well as intercropping. Key coping practices reported by the study participants included reduction of food consumption, off-farm jobs, selling livestock, charcoal making and reliance on remittances. The results further revealed that social cohesion mechanisms or collective action play a key role in helping farmers cope and adapt to climate change while improving soil fertility. Social cohesion is mainly reflected in two different structures depending on gender. While diverse challenges of innovation adoption exist, socio-cultural barriers differ by gender. The study recommends the integration of farmers throughout the innovation development process and proposes the need for a concerted effort to strengthen land tenure security policies, ensuring equitable access to farmlands for all genders.
Erfolgsfaktoren von Kooperationen innerhalb der Internationalisierungsstrategien von Familienunternehmen
(2012) Ostertag, Martina M.; Müller, Christoph
Considering the global economy, one can observe for some years now the growing importance of internationalization. Increasingly companies are faced with growing competitive pressure. New, foreign competitors are entering the market and more and more companies are taking advantage of the opportunities that arise in the context to globalization. Often the first step for opening new markets is to develop sales partnerships with businesses in the target country. Based on the development of international distribution partnerships, family run businesses are considering co operations. The goal is to identify specific success factors for co-operations, based on the concept of the determinants of success and the special characteristics of family run businesses and based thereon, under the aspect of the effectuation model, to develop an ideal co-operation process. The focus is on the highest possible practical use for family run businesses that want to be active internationally by setting up sales co-operations. Taking into consideration uncertainty, the result is an optimized process, which primarily meets the special needs of family run businesses and allows a structured implementation of the defined international strategy.
Sustainability certification in the digital era: a qualitative analysis of sustainability reports across product categories
(2026) Boller, Meta Leonie; Grabinger, Toni; Zurwehme, Annikka; Krupitzer, Christian
The food industry faces growing pressure to align sustainability goals with the rapid advance of digital technologies. This study explores how digitalization supports and transforms sustainability certification practices across diverse food product categories. Novelty lies in examining the interplay between digital technologies and sustainability reporting intensity, offering insights into how firms communicate and operationalize sustainability commitments. A qualitative content analysis was conducted on the sustainability reports of 21 companies using MAXQDA software, assessing the frequency and depth of reporting on sustainability focus topics and digital tools applied. The study includes multiple food product categories, such as coffee and tea, chocolate, grain products, dairy products, beverages, meat and fish, and tropical fruits. Results show that larger firms and those with higher turnover report more frequently and comprehensively on sustainability and digitalization. Three clusters of companies were identified, each reflecting shared sustainability challenges rather than specific product categories. The findings suggest that the relevance of digital technologies is more closely linked to addressing these cross-cutting sustainability challenges, and that high-value product segments provide the most promising starting points for integrating digital technologies into certification processes.
Towards more nuanced narratives in bioeconomy strategies and policy documents to support knowledge-driven sustainability transitions
(2025) Stoye, Juliane; Schlaile, Michael P.; von Cossel, Moritz; Bertacchi, Stefano; Escórcio, Rita; Winkler, Bastian; Curran, Thomas P.; Ní Chléirigh, Laoise; Nic an Bhaird, Máire; Klakla, Jan Bazyli; Nachtergaele, Pieter; Ciantar, Hailey; Scheurich, Philipp; Lewandowski, Iris; Reinmuth, Evelyn; Hopmans, Jan
The bioeconomy has been discussed as a key strategy for addressing sustainability challenges, particularly regarding the transition from fossil-based to bio-based systems, in numerous national and supranational strategies and policy documents related to the bioeconomy. However, public understanding of and engagement with the bioeconomy remains limited. This is partly due to the bias of many bioeconomy strategies and policy documents towards technological solutions that tend to overlook the social, normative, and transformative dimensions of systemic change as well as the necessary knowledge. This opinion paper explores the potential of narratives as a means of communicating bioeconomy research in public policy, with the aim of addressing the communication gap between science, policy, and society. When applied in responsible and nuanced ways that acknowledge their embeddedness and context, bioeconomy (policy) narratives can support sensemaking for science communication, improve public understanding, facilitate stakeholder engagement and behavioural change. We argue that such narrative approaches can help to create narrative ‘boundary objects’ that can support more inclusive and participatory processes, enabling the co-creation of transformative knowledge for bioeconomy transitions with stakeholders as active participants. In summary, we highlight several opportunities, as well as limitations and implications, that could inform future work on bioeconomy narratives.
Transforming agricultural waste from mediterranean fruits into renewable materials and products with a circular and digital approach
(2025) Castagna, Antonella; Aboudia, Aouatif; Guendouz, Amine; Scieuzo, Carmen; Falabella, Patrizia; Matthes, Julia; Schmid, Markus; Drissner, David; Allais, Florent; Chadni, Morad; Cravotto, Christian; Senge, Julia; Krupitzer, Christian; Canesi, Ilaria; Spinelli, Daniele; Drira, Fadoua; Ben Hlima, Hajer; Abdelkafi, Slim; Konstantinou, Ioannis; Albanis, Triantafyllos; Yfanti, Paraskevi; Lekka, Marilena E.; Lazzeri, Andrea; Aliotta, Laura; Gigante, Vito; Coltelli, Maria-Beatrice; Hilliou, Loic
The Mediterranean area is one of the major global producers of agricultural food. However, along the entire supply chain—from farming to food distribution and consumption—food waste represents a significant fraction. Additionally, plant waste residues generated during the cultivation of specific fruits and vegetables must also be considered. This heterogeneous biomass is a valuable source of bioactive compounds and materials that can be transformed into high-performance functional products. By analyzing technical and scientific literature, this review identifies extraction, composite production, and bioconversion as the main strategies for valorizing agricultural by-products and waste. The advantages of these approaches as well as efficiency gains through digitalization are discussed, along with their potential applications in the Mediterranean region to support new research activities and bioeconomic initiatives. Moreover, the review highlights the challenges and disadvantages associated with waste valorization, providing a critical comparison of different studies to offer a comprehensive perspective on the topic. The objective of this review is to evaluate the potential of agricultural waste valorization, identifying effective strategies while also considering their limitations, to contribute to the development of sustainable and innovative solutions in Mediterranean bioeconomy.
