This paper is focused on intervention scenarios for smallholder potato value chains in Kenya that improve yields, reduce losses, minimize greenhouse gas (GHG) emissions and increase economic performance and food security. For that, business models and GHG emission estimates are developed, based on the existing data, combined with relevancy and time-to-impact analysis using practical real-life information from stakeholders in the potato sector, which is the second largest agricultural crop in Kenya after maize. The results show that profitability, environmental improvement and food security can go hand in hand with realistic short-term interventions for potato production at smallholder farms.

Increased urbanization rates pose crucial challenges in terms of food systems’ sustainability, including urban food waste (FW). The global narrative around FW has focused mainly on Western countries, but recent evidence shows that FW is also a major issue in the developing world. The objective of this article is to define the characteristics and drivers of urban FW in low- and middle-income countries (LMIC). We firstly present a tailor-made three-step approach to identify urban FW hotspots in LMIC, understand the main drivers and design and implement prevention and reduction interventions considering LMIC food system characteristics. We then draw on results from four different urban FW case studies based in Nairobi (Kenya) and Dhaka (Bangladesh) and discuss their characteristics in light of the proposed approach. The case of Nairobi focuses on quantifying and understanding possible drivers of household FW in Kibera and characterizing FW disposal through a household survey (N = 774). The other three studies examine FW at retail, food service and institutional levels for onions, mangoes and beef in Dhaka. The results confirm that FW happens at the urban supply chain level, particularly among mobile vendors but also among households living below the poverty line. The article thus urges LMIC municipalities to consider urban FW strategies as a key action to tackle food security, environmental issues and FW management challenges.

Driven by global climate concerns, seaports have formulated sustainability goals, which also require sustainability gains in the fast growing temperature-controlled logistics market—increasing energy efficiency, reducing waste, and streamlining logistics processes. This, however, requires cooperation and buy-in from a wide range of stakeholders. To explore the barriers and facilitators of such a transition, we map the interests and attitudes of cold chain actors in the Port of Rotterdam regarding sustainability issues in reefer transportation and cold chains. We identify a limited number of broadly shared perspectives using Q-methodology—a survey-based method to study subjective viewpoints (originating from psychology) that has been used only rarely in the freight transport field. The analysis yields four ‘dominant’ perspectives that together account for 46% of the variation among stakeholder viewpoints. We label these perspectives “sustainability as part of strategy”, “short term constraints”, “optimistic about technology, limited role for policy”, and “long run willingness under risk avoidance.” These perspectives are characterized by multiple factors, including the evaluation of organizational capabilities, expectations from policymakers and technology, and the time horizon stakeholder organizations consider regarding sustainability concerns. From the findings, we derive recommendations for managers and policy makers to facilitate stakeholder dialogue and possibly convergence and coalition building.

Strategic alliances in the container shipping sector, and requirements imposed by consolidated hinterland modalities such as trains and barges, have resulted in container terminals facing increasing pressures to cooperate to handle increasingly intertwined container flows. However, concession agreements and market conditions often also pressure terminals to compete. This paper aims to help understand how pressures for competition and cooperation conflict, what problems this causes, what drives these tensions, and how these can be resolved. The drivers of port competitiveness are generally conceptualized as straightforward criteria related to costs, efficiency, location, and infrastructure. Because of the focus on these 'hard', quantifiable factors, the qualitative relational underpinnings of port performance are often overlooked. This paper explores how inter-organizational relations function as a major underpinning of port performance and competitiveness. Interviews with a representative selection of stakeholders in the Port of Rotterdam reveal the problems that can occur when cooperation between terminals is under pressure. These problems relate to deficiencies in inter-organizational relationships, which do not tend to arise spontaneously in a competitive context. This paper provides a framework that helps understand how firms can simultaneously balance pressures for competition and imperatives for cross-firm integration and cooperation. Several technical and organizational solutions are suggested, but effective implementation depends on various tacit factors - including trust, shared values, and a sense of community - that determine stakeholders' willingness to commit and cooperate.
