Abstract
Sustainable intensification technologies (SITs) are widely promoted across sub-Saharan Africa to improve productivity and reduce land degradation. However, their relationship with land use efficiency remains insufficiently understood. This study uses a translog stochastic frontier model and farm-level data from 372 smallholder maize farmers in northern Ghana to examine how SIT adoption is associated with technical land use efficiency (TLUE). On average, SIT adopters are 21% more land efficient than non-adopters, requiring approximately 24% less land to achieve the same output. Since land is treated as a fixed input in the frontier, the TLUE score directly reflects the effective land needed to produce observed yields. Adoption of improved seed, balanced fertilizer use, and agroecological practices is linked to better resource use, with the largest gains among farmers who initially operate furthest from the frontier. These efficiency improvements may reduce pressure for cropland expansion and support sustainable land management, especially when combined with enabling conditions such as credit access, extension support, and secure tenure. This study provides novel empirical evidence on how productivity improvements through SIT can enhance land use efficiency and contribute to land sparing outcomes. The findings offer insights for policies targeting land degradation neutrality and inclusive agricultural transformation in Ghana and similar contexts.

Although community supported agriculture (CSA) is generally considered a potent alternative to the globalized food system, the capacity of CSA farms to foster community support in agriculture has been questioned due to low engagement of members at the farm and high member turnover rates. In this study, I consider the case of member-driven CSA farms and explore the potential of this CSA model to increase member engagement in CSA farming. Using an inductive, phenomenon-first approach to research, I compare the cases of four Norwegian member-driven CSA farms to describe how they engage members at the farm and explore the factors influencing member engagement. The on-farm participant observation, focus group interviews with farm coordinators and members survey revealed that Norwegian member-driven CSAs significantly engage members in all aspects of the farm operations. Yet, the differences observed between cases showed that member engagement depend on the capacity of the farm to create the right conditions for collaboration. Although the member-driven model has the potential to increase member engagement in CSA farming, the preferences of members, the opinions and engagement of coordinators, the size of the farm, the number of years of operation and the external support received by the farm, are five factors that affect the capacity of the CSA farm to collaborate with members. Ultimately, this study concludes that achieving community engagement in member-driven CSAs depends less on their organizational model and more on the specific conditions that facilitate collaboration and member engagement.

A survey including 3112 responses from individual end users of wood cladding, from Norway, Sweden and Germany, was conducted with questions related to their experience and preferences regarding cladding with and without coatings. Based on these results and established scientific understanding of Service Life Prediction (SLP) of wood cladding, two decision trees were provided to guide end users in selecting a suitable material to meet their expectations when planning a new cladding. This approach makes the users reflect on maintenance requirements and aesthetic changes rather than choosing a product solely based on initial aesthetic appeal.
