This paper evaluated the energy and emergy characters and indicators of the protected grape production system in the five major producing areas in China based on the emergy analysis. The research results indicate that the total emergy input in the Northwest region is the largest. The protected cultivation in all the five regions is heavily dependent on the purchased resource and nonrenewable resource emergy. The Southwest region is found to have the lowest environmental pressure and the highest sustainability.

The purpose of this paper is to identify beef cattle production systems in the northwestern part of the state of Paraná, Brazil. To achieve this, interviews with 42 randomly selected cattle breeders were conducted between the months of November and December 2016 to describe the reality of the farms of this region. These interviews were carried out through a semi-structured questionnaire containing 49 questions pertaining to the reality of farms regarding herd management and property (nutrition, health, reproduction, and animal welfare), environment care, property area, and realized activities. Additionally, this questionnaire described the requirements of slaughterhouse for animal housing and the values obtained by the animals marketed according to the producers. After the interviews were carried out, a data bank was created using the software Microsoft Excel (ver. 2010). The data was later transferred to the software PASW 18 for Windows to perform multivariate statistical analyses. Defining the most representative variables was realizedwith multivariate statistical analysis, and these were represented by factor analysis, cluster analysis, and discriminant analysis to define the production systems. Through statistical analysis, three different systems were defined: the first production system has 18, the second production system five, and the third production system has 18 cattle breeders. The three systems found in the northwest region of the state of Paraná have different production and marketing characteristics, with the second system being superior to the other systems.

An investigation was conducted with a view to observing the performance of two gladiolus genotypes during the rainy summer under poly tunnel production system. The genotype GL-027 produced taller plants (73.8 cm) with longer spike (97.2 cm) and longer rachis (51.7 cm) compared to the genotype GL-023. In respect of spike length (97.0 cm), rachis length (54.4 cm), weight of corm per plant (16.0g) and weight of cormel per plant (30.3 g), 1 July planting was better than in 1 May planting. Plants grown under poly tunnel produced flower earlier (82.5 days) compared to plants grown without poly tunnel (84.6 days). Although difference of only two days in flower initiation is of no significance, but plants grown under poly tunnel performed better in respect of number of florets per spike (12.8), number of cormels per plant (8.2), weight of corm per plant (16.0 g) and weight of cormels per plant (30.6 g) than the plants grown without poly tunnel.

A nearshore wave forecasting system was implemented to elevate the ocean information resources in the US Pacific Northwest region. This implementation brings the US State of Oregon and the Southwest region of the state of Washington to the same level of prediction as the neighboring state of California and other regions of the country. It was achieved using the Wavewatch III numerical wave model, which was validated in intermediate to shallow waters. The forecasting system provides data at a 30 arc-second resolution from the shelf break up to a depth of 20 meters. The data is distributed to the public at no cost as part of a greater initiative put together by the Networked Association of Ocean Observing Systems. Information generated by this implementation is presently being used to provide boundary conditions to localized applications in the region as well as to beach users.

Abstract Background The factors affecting host-pathogen ecology in terms of the microbiome remain poorly studied. Chickens are a key source of protein with gut health heavily dependent on the complex microbiome which has key roles in nutrient assimilation and vitamin and amino acid biosynthesis. The chicken gut microbiome may be influenced by extrinsic production system parameters such as Placement Birds/m2 (stocking density), feed type and additives. Such parameters, in addition to on-farm biosecurity may influence performance and also pathogenic bacterial numbers such as Campylobacter. In this study, three different production systems ‘Normal’ (N), ‘Higher Welfare’ (HW) and ‘Omega-3 Higher Welfare’ (O) were investigated in an industrial farm environment at day 7 and day 30 with a range of extrinsic parameters correlating performance with microbial dynamics and Campylobacter presence. Results Our data identified production system N as significantly dissimilar from production systems HW and O when comparing the prevalence of genera. An increase in Placement Birds/m2 density led to a decrease in environmental pressure influencing the microbial community structure. Prevalence of genera, such as Eisenbergiella within HW and O, and likewise Alistipes within N were representative. These genera have roles directly relating to energy metabolism, amino acid, nucleotide and short chain fatty acid (SCFA) utilisation. Thus, an association exists between consistent and differentiating parameters of the production systems that affect feed utilisation, leading to competitive exclusion of genera based on competition for nutrients and other factors. Campylobacter was identified within specific production system and presence was linked with the increased diversity and increased environmental pressure on microbial community structure. Addition of Omega-3 though did alter prevalence of specific genera, in our analysis did not differentiate itself from HW production system. However, Omega-3 was linked with a positive impact on weight gain. Conclusions Overall, our results show that microbial communities in different industrial production systems are deterministic in elucidating the underlying biological confounders, and these recommendations are transferable to farm practices and diet manipulation leading to improved performance and better intervention strategies against Campylobacter within the food chain.

The progressive development of the agricultural production system is the foundation for promoting the rapid and efficient growth of the regional economy. In this study, the irrigation benefit allocation coefficient for the agricultural irrigation system of Henan Province from 1999 to 2014 was comprehensively investigated on the basis of the theory of emergy analysis. The process and mechanism of the variation coefficient were explored using ArcGIS 10.1 (Environmental System Research Institute, Redlands, USA) and SPSS 21.0 software (IBM, Chicago, USA), and the results were shown spatially. From the analysis and results, the emergy investment and yield in the Henan agricultural production system were found to continuously increase with annual increases of 2.26% and 4.22%, respectively. However, the irrigation benefit allocation coefficient of Henan showed a continuous downward trend with a total decrease of 0.026 due to precipitation. The irrigation benefit allocation coefficient fluctuated owing to the combined influence of multiple restraining factors, among which chemical fertilizers and pesticides played the dominant role. Therefore, comprehensive application of multiple emergy investment methods was critical for boosting emergy yield.

The Anglophone Crisis is a conflict in the Southern Cameroons region of Cameroon, part of the long-standing Anglophone problem. The purpose of this study is to analyze the origin of the Anglophone problem in Cameroon. Equally, to identify and analyze the causes of the present Anglophone crisis in Cameroon and the rule of the US in finding a solution to the crisis. Research method was based on analyzing policy documents of US, Cameroon and the separatist of the Anglophone regions. Following up latest developments of the crisis was another main method used in the study. In September 2017, separatists in the Anglophone territories of Northwest Region and Southwest Region (collectively known as Southern Cameroons) declared the independence of Ambazonia and began fighting against the Government of Cameroon. Starting as a low-scale insurgency, the conflict spread to most parts of the Anglophone regions within a year. By the summer of 2019, the government controlled the major cities and parts of the countryside, while the separatists held parts of the countryside and regularly appeared in the major cities.The war has killed approximately 3,000 people and forced more than half a million people to flee their homes. Although 2019 has seen the first known instance of dialogue between Cameroon and the separatists, as well as a state-organized national dialogue and the granting of a special status to the Anglophone regions, the war continued to intensify in late 2019. The February 2020 Cameroonian parliamentary election brought further escalation, as the separatists became more assertive while Cameroon deployed additional forces. While the COVID-19 pandemic saw one armed group (SOCADEF) declare a unilateral ceasefire to combat the spread of the virus, other groups and the Cameroonian government ignored calls to follow suit and kept on fighting. With the enormous pressure by the US on the Cameroonian government, the government of Cameroon has not yet heed the call to stop fighting with the rebels of the Anglophone regions.
