“…Analyses at the meso level account for over 50% of the total and are mainly applied to Europe and China, and to the food and agriculture, technology and construction sectors. Topics discussed in the food and agriculture sector include: how to incorporate CE management and assessment in the production, consumption and waste stages [14,[29][30][31], impact on agriculture, cost reduction, and increased profitability [32,33]. Analysing the CE as a business strategy is also applied to the technology and communications sectors [34,35].…”

The concepts of bioeconomy, green economy and circular economy share the common objective of developing a sustainable economy, and they attract enormous political, academic, social and business interest. However, an analysis of these concepts in the fields of economics and business management is lacking. The objective of this article is to classify the publications on these topics by subject of study, to analyse trends in publications and to guide researchers interested in selecting articles. The review was performed using Scopus for the period 1960 to 2017. Four hundred and forty-nine publications were obtained and classified into 17 categories. The results show that the existing literature is rich in analysing implemented policies and issues related to the strategies and organizational models of companies looking for a more sustainable path, and research in China and the European Union is highlighted. However, there is still a long way to go in researching implemented case studies and evaluating the economic impact of these concepts. For this to happen, the need to promote, encourage and support companies to implement cleaner production and approach a more sustainable path must be prioritised. Possible gaps in current research that allow future lines of work are also identified.

“…Further, grass-legume mixture 6 removed a lower quantity of P than grass-legume mixtures 1, 2, 5, 8, 16, 17, and 18 (Table 5). During 2018, the grass-legume mixture 8, removed a greater amount of P than red and white clover monocultures, and grass-legume mixtures 1,2,10,11,12,13,16, and 18 ( Table 5). The monocultures of red and white clover removed the least amount of P during 2018 ( Table 5).…”

“…The total P removed after two years was different among forage systems (P < 0.001) in this study. The two cultivars of tall fescue grass monoculture removed a greater quantity of P after two years than the grass-legume mixtures 1,3,6,10,11,12,13,14,16,17, and the three monoculture legumes (Table 5). Additionally, grass-legume mixtures 8 and 17 removed a greater quantity of P after two years than grass-legume mixtures 3,10,11,12,14,18, and all three monoculture legumes ( Table 5).…”

Grass–Legume Forage Systems Effect on Phosphorus Removal from a Grassland Historically Irrigated with Reclaimed Wastewater

The utilization of reclaimed wastewater is a suitable and sustainable approach to agriculture production in water-scarce regions. However, even though the wastewater is treated to reduce nutrient concentration such as phosphorus, the 10,600 to 14,006 m3 of water applied ha−1 year−1 on grass and alfalfa hay crops in Nevada can lead to soil phosphorus buildup over an extended period. This study evaluated the effectiveness of forage systems (FS) of monoculture grass, monoculture legume, and their mixtures on herbage accumulation, tissue phosphorus concentration, and quantity of phosphorus removed from a grassland under wastewater irrigation. The study was carried out at the Main Station Field laboratory in Reno, Nevada, USA. A total of 23 FS using tall fescue (Schedonorus arundinaceus (Schreb.) Dumort), alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) in monocultures or grass–legume mixtures (25:75, 50:50, and 75:25) based on seeding rate were used. The response variables were herbage accumulation (HA), tissue phosphorus concentration, and phosphorus removal. Forage systems means were considered different P ≤ 0.05. Herbage accumulation, tissue phosphorus concentration, and phosphorus removal differed among FS and year. Herbage accumulation was similar for the grass monocultures (10.5 Mg ha−1; SE = 1.1) and the majority of the grass–legume mixtures (9.0 Mg ha−1; SE = 1.1) but both systems had greater HA than legumes monoculture (4.3 Mg ha−1; SE = 1.1). The legume monocultures of alfalfa and white clover had the greatest phosphorus concentrations (10.9 g kg−1 dry matter; SE = 0.44) among all FS. Total phosphorus removed was least among legume monocultures (34.0 kg P ha−1; SE = 6.2) in this study and generally similar for grass monocultures (67.4 kg P ha−1; SE = 6.2) and grass–legume mixtures of 75:25 (61.7 kg P ha−1; SE = 6.2). Based on the response variables, agronomic, and environmental considerations a grass–legume mixture that includes 75:25 or even a 50:50 seeding rate ratio will be suitable options for phosphorus removal from phosphorus enriched grasslands in semiarid ecosystems that utilized wastewater for irrigation.

“…The conceptual framing used for analyzing the socioeconomic impact of GE on agricultural value chains draws on the value chain concept [50]. The value chain concept was first popularized by Porter [51] and has been increasingly used as a framework for studying innovations in agricultural value chains [52][53][54]. Value chains describe "the full range of activities which are required to bring a product or service from conception, through the different phases of production (involving a combination of physical transformation and the input of various producer services), delivery to final consumers, and final disposal after use" [50] (p. 4).…”

Genome editing (GE) is gaining increasing importance in plant breeding, since it provides opportunities to develop improved crops with high precision and speed. However, little is known about the socioeconomic impact of genome editing on agricultural value chains. This qualitative study analyzes how genome-edited crops could affect agriculture value chains. Based on the hypothetical case of producing and processing fungal-resistant and coeliac-safe wheat in Germany, we conducted semi-structured, in-depth interviews with associations and companies operating in the value chains of wheat. A value chain analysis and qualitative content analysis were combined to assess the costs and benefits of the crops studied along the value chains of wheat. The results show that the use of fungal-resistant and coeliac-safe wheat can provide benefits at each step of the value chains. Fungal-resistant wheat benefits actors by reducing the problems and costs resulting from fungal-diseases and mycotoxins. Coeliac-safe wheat benefits actors by producing high value-added products, which can be safely consumed by patients suffering from coeliac disease. However, the results also show that low acceptance of GE by society and food retailers poses a significant barrier for the use of genome-edited crops in agricultural value chains.
