This report presents findings from a qualitative survey among actors involved in the production and sale of local food in Oslo and Bristol, with a focus on sales models and challenges and opportunities for direct sales. The actors in Oslo and Bristol had largely the same motivation for local food sales, including environmental sustainability, transparency in the supply chain, creating community, supporting farmers, sharing knowledge about food and agriculture, as well as being a counterweight to the mainstream food system. Climate crisis and food safety were stronger motivational factors among actors in Bristol than in Oslo, while in Oslo there was more emphasis on the importance of local sales channels for food diversity and quality. Several interviewees pointed to lack of economic profitability as one of the most important challenges for the local food producers. It requires a great deal of work both with production, marketing and sales to be economically successful as a small-scale producer. At the same time, buying local food often requires more time, effort and money from consumers compared to shopping in grocery stores. The report points to several possible solutions to these challenges: increased demand for local food due to changes in attitudes, increased cooperation between producers, sales channels, organizations and public authorities to reduce competition and find common solutions, as well as the development of common digital platforms that can create economies of scale and make marketing and deliveries more efficient. It is also important to look at how the public sector, both through grants, procurement and guidance, can facilitate increased production and sale of local food.

Increasing soil organic carbon is promoted as a negative emission technology for the agricultural sector with a potential co-benefit for climate adaptation due to increased soil water retention. Field-scale hydrological models are powerful tools for evaluating how the agricultural systems would respond to the changing climate in upcoming years and decades, for predicting impacts, and for looking for measures that would help decrease drought-driven crop stress under current and future climatic conditions. We quantified how different levels of soil organic carbon (SOC) additions at varied soil depths are expected to influence drought-induced transpiration reduction (Treddry) in maize cultivated in Switzerland. Parameterization of the model based on a pedotransfer function (PTF) was validated against soil moisture data from a long-term lysimeter experiment with a typical Swiss soil, and the model was subsequently applied under climate forcing between 1981 until 2099, representative of three distinct climatic sites of Switzerland. We used the same PTF to indirectly assess the effects of SOC additions at different depths on soil hydraulic properties. We found a threshold in both the added amount of SOC (2 % added) and the depth of sequestering that SOC (top 65 cm), beyond which any additional benefit appears to be substantially reduced. However, adding at least 2 % SOC down to at least 65 cm depth can reduce Treddry in maize, i.e. increase transpiration annually but mostly at the onset of summer drought, by almost 40 mm. We argue that SOC increases in subsoils can play a supporting role in mitigating drought impacts in rain-fed cropping in Switzerland.
