Abundant natural resources are the basis of urbanisation and industrialisation. Citizens are the key factor in promoting a sustainable supply of natural resources and the high-quality development of urban areas. This study focuses on the co-production behaviours of citizens regarding urban natural resource assets in the age of big data, and uses the latent Dirichlet allocation algorithm and the stepwise regression analysis method to evaluate citizens’ experiences and feelings related to the urban capitalisation of natural resources. Results show that, firstly, the machine learning algorithm based on natural language processing can effectively identify and deal with the demands of urban natural resource assets. Secondly, in the experience of urban natural resources, citizens pay more attention to the combination of history, culture, infrastructure and natural landscape. Unique natural resource can enhance citizens’ sense of participation. Finally, the scenery, entertainment and quality and value of urban natural resources are the influencing factors of citizens’ satisfaction.

Consumers associate a bright-cherry red color of beefwith freshness and wholesomeness. Any deviation from a bright red color leadsto a discounted price or beef is discarded. Limited data is currently availableon the economic losses due to retail beef discoloration. Therefore, theobjective of the study was to estimate economic losses, the amount of beefdiscarded, natural resource wastage, and environmental impact due to beefdiscoloration. One-year data of total beef sales, total beef discarded, and discountedsale values were collected from two national retail chains and one retailstore. The two retail chains were located throughout the US, and the one retailstore was located in Southern US. The US beef system life cycle parameters frompublished literature were used to calculate the impact of discarded meat on waterand energy use and greenhouse gas emissions. The data from three stores weremodeled to calculate annual loss due to discoloration from the US retail beefsales. The data indicated that total beef sales from two major retail chainsand one retail store was 1.1 billion pounds of steaks and ground beef for theone-year period. This amount of beef corresponds to approximately 6.5% of totalretail sales of steaks and ground beef in the US. The amount of beef discardedfrom two major retail chains and one retail store corresponds to 29.7 millionpounds. Based on modeled data, the amount of beef discarded annually due todiscoloration within the US retail beef industry corresponds to 429 millionpounds, with another 1.8 billion pounds sold at a discount. The results indicatethat the US beef industry losses $3.745 billion annually due to discoloration. Thetotal amount of beef discarded per year in the US corresponds to 429 millionpounds, which represents wasting 780,000 animals and the associated naturalresources used in their production. A 1% decrease in discolored beef in the UScould reduce natural resource waste and environmental impacts by 23.95 billionL in water, 96.88 billion mega Joules in energy consumed, and 0.40 million tonsof carbon dioxide equivalent emission along the beef upstream value chain.Therefore, novel technologies to improve meat color stability could improvebeef production’s sustainability and limit wastage of nutritious beef.

AbstractMany Pacific countries and territories embrace an officially recognized ‘ridge-to-reef’ approach to environmental management. This is the case of Fiji, where the Lau Seascape Strategy 2018–2030, led by Conservation International, aims for integrated natural resource management across 335 895 km2. This area includes Cicia Island, which deserves particular attention since, years before the design of the Lau Seascape Strategy, its population developed its own informal ridge-to-reef scheme, involving a combination of certified organic agriculture and locally managed marine closures. Based on 1 month of ethnographic fieldwork, this paper presents this scheme and highlights local perception and conceptualization of its positive effects on both the land and the sea. These reflect the iTaukei (Indigenous Fijian) concept of vanua, which intrinsically connects the health of the land, the sea, and their (human and non-human) dwellers, while stressing the importance of addressing land-sea processes and management efforts beyond an ecological perspective, i.e. through an engagement with the iTaukei relational ontology.
