This paper investigates the adoption of digital technologies for food waste reduction and prevention in Norway. It goes beyond studying one single technology, aiming to have a broad understanding of digital technology adoption as ‘a (digital) innovation system’ by applying a multiple case study of four different digital technologies used by companies in the food and hospitality sector in Norway. I strive to understand why Norwegian companies, i.e. food producers, grocery chains, restaurants, and cafes (or technology adopters) adopt the technologies in the first place and what benefits and challenges they may encounter along with the adoption. Data inputs for this paper are gathered from semi-structured interviews with several technology adopters. Empirical insights show that the benefits include economic advantage by reducing the amount of waste and increased awareness among employees. However, there are at least several challenges concerning the adoption of digital technologies. Some adopters found that the digital technologies were too costly, incompatible with their internal (IT) systems, or mismatched economic models. Another challenge is employee awareness about food waste and related digital technologies. The paper sheds light on the multiple and complex challenges in adopting digital technologies for food waste prevention and reduction.

Chapter 6 provides a summary of research findings from the case studies in India that showed significant benefits of another climate-smart rice system, namely the direct seeded rice (DSR), which shows positive outcomes compared to puddled transplanted rice in terms of (i) higher water productivity, (ii) reduction in labour and production costs, and (iii) lower methane emissions. However, there are some challenges for adopting DSR which include poor weed control, need for specific water and nutrient management, availability of suitable varieties for DSR, increased damage by soil pathogens and nutrient disorders, especially N and micronutrients. Possible solutions to overcome these challenges that will make it easier for adoption by farmers will be analysed in this chapter. Field data/evidence from India and other previous studies under both dry and wet conditions were presented to support the solutions. The options for scaling up DSR combined by need-based farmer trainings, accessibility to good quality seeds, availability and use of drum seeders and selective herbicides were discussed.

Light exposure of potatoes induces formation of both chlorophyll (greening) and of toxic glycoalkaloids (GAs). Greening leads to rejection by consumers and thus to food waste and economic loss. The aim of this study was to (1) study light sensitivity with respect to colour changes and GA development for different Norwegian grown potato cultivars stored at 20 °C and (2) evaluate the light protective effect of selected packaging materials on colour development in cv. Folva at 6 °C and 20 °C. Potatoes of seven cultivars were stored under LED illumination for 4 days at 20 °C. Changes in colour were measured during storage by Minolta Chroma meter and by visually assessing the limit for unacceptable change of colour. The tested cultivars became unacceptable at different times (24–60 h) and differed both in absolute colour values and relative changes of values. The levels of total glycoalkaloids in cultivars with and without light exposure did not correspond well to the changes in colour. Potatoes of cultivar Folva were packaged in materials with different light barrier properties, followed by LED illumination for 4 days at 20 °C and 18 days at 6 °C. None of the tested packaging types provided sufficient protection from light. All potatoes at 20 °C were unacceptably green after 2 days in light (16 h/day) while the potatoes at 6 °C were unacceptably green after 9 days. Packaging material for potatoes cv. Folva should aim for a total light transmittance below 0.02 W/m2 to avoid development of green colour during light exposure at 20 °C in grocery stores.

This work aims to determine the effect of genotype x environment (GxE) interaction that influence blackcurrant (Ribes nigrum) fruit quality. We applied metabolomics-driven analysis on fruits from four cultivars grown in contrasting European-locations over two seasons. By integrating metabolomics and sensory analysis, we also defined specific metabolic signatures associated with consumer acceptance. Our results showed that rainfall is a crucial factor associated with accumulation of delphinidin- and cyanidin-3-O-glucoside, the two mayor blackcurrant pigments meanwhile temperature affects the main organic acid levels which can be decisive for fruit taste. Sensorial analysis showed that increases in terpenoid and acetate ester volatiles were strongly associated with higher appreciation score, while proacacipetalin, a cyanogenic-glycoside, was positively associated to bitter taste. Our results pave the way for the selection of high-quality cultivars and suitable production sites for blackcurrant cultivation.

The reported annual temperature increase and significant precipitation drop in Armenia impact the country’s ecosystems and biodiversity. The present study surveyed the geographical distribution of the local wild beet species under the ongoing climate change conditions. We showed that B. lomatogona, B. corolliflora and B. macrorhiza are sensitive to climate change and were affected to various degrees, depending on their location. The most affected species was B. lomatogona, which is at the verge of extinction. Migration for ca. 90 and 200–300 m up the mountain belt was recorded for B. lomatogona and B. macrorhiza, respectively. B. corolliflora was found at 100–150 m lower altitudes than in the 1980s. A general reduction in the beet’s population size in the native habitats was observed, with an increased number of plants within the populations, recorded for B. corolliflora and B. macrorhiza. A new natural hybrid Beta x intermedium Aloyan between B. corolliflora and B. macrorhiza was described and confirmed using chloroplast DNA trnL-trnF intergenic spacer (LF) and partially sequenced alcohol dehydrogenase (adh) of nuclear DNA. An overview of the wild beets reported in Armenia with the taxonomic background, morphological features, and distribution is provided. Conservation measures for preservation of these genetic resources are presented.

The City of Bristol has a long history and well-established practices in urban farming and city food system planning. Farms apply different urban business models that take advantage of the proximity to the city by providing food to city dwellers. Dedicated retailers and restaurants specialize in local food, and a variety of organisations facilitate and promote a resilient and sustainable urban food system.
