Les appuis de l’action collective mobilisés dans les transitions agroécologiques. Enseignements de l’analyse de cinq collectifs d’agriculteurs en Rhône-Alpes
Authors: Cardona Aurélie , Brives Hélène , Lamine Claire , Godet Jacques , Gouttenoire Lucie , Rénier Louis
Published: April 2021

L’action collective et la coopération entre des acteurs aux connaissances et pratiques variées contribuent à développer et partager de nouvelles visions, valeurs, ressources matérielles, qui étayent les processus de transition agroécologique. Ces dernières années, afin d’encourager les transitions, les incitations pour soutenir les collectifs d’agriculteurs se multiplient. Cependant, la coordination d’acteurs n’ayant pas d’habitude de travail en commun ne va pas toujours de soi. Dans cet article, nous identifions les conditions d’émergence de ces collectifs et les manières dont les acteurs y participant parviennent à se coordonner pour s’engager collectivement dans des processus de transitions agroécologiques. À partir de l’analyse compréhensive de cinq collectifs d’agriculteurs, nous montrons que l’action collective en faveur des transitions agroécologiques repose sur la capacité à mobiliser et à assembler des appuis hétérogènes dans le temps. Ces appuis sont : les relations interpersonnelles, le matériel technique, les moyens et supports de connaissances, les soutiens publics et financiers, les acteurs pivots/animateurs. Les transitions agroécologiques résultent alors d’un agencement singulier de ces appuis dans un processus de construction pas-à-pas articulant à la fois des activités planifiées et des activités spontanées issues d’opportunités ou de contraintes rencontrées. Nos résultats bousculent ainsi les visions planificatrices de la trajectoire des collectifs en pointant le rôle des dynamiques d’émergence pour leur pérennité.

Authors: Yu Lulu , Li Zhao
Published: April 2021

At the early stage of development, China has a monotonous energy consumption structure dominated by coal, which damages the environment and has adverse impacts on the economy and sustainable development of the country. It is urgent to change the existing energy structure to reach the goal of sustainable development and improve people’s living standard. The U.S., as the world’s strongest power, has been where China is now, so it is feasible to draw lessons from the U.S in its energy consumption structure. In this study, massive data about the changes in the energy consumption structure are collected and processed, and the types of energy in China and the U.S. are compared. In 2030, China will become the largest consumer of petroleum, and the problems in China’s energy consumption such as supply-demand imbalance, low utilization of energy, and overdependence on imports, will rear their ugly heads. Thus, through theoretical analysis and data analysis, we analyze China’s current structure of energy consumption, its similarity with and difference from that in the U.S., and propose suggestions to improve China’s energy consumption structure.

The Construction of the Derivative Value of Heritage Tourism on the Basis of Symbolic Consumption
Authors: Zhao Chunhua
Published: April 2021

As a part of creative cultural industry, heritage tourism combines cultural, historical, artistic and scientific values. It includes both spiritual consumption and material consumption. It is not only a social and cultural phenomenon, but also an economic phenomenon, upgrading from sightseeing to purchasing goods and then to cultural experience. The process of heritage tourism experience is actually a process of encoding symbols. The attraction of heritage tourism derives from the symbolic significance of tourism itself. In essence, tourism consumption is a kind of symbolic consumption, which forms tourism motivation based on the attraction of indicative symbols, and then evolves emotional satisfaction in a symbolic environment. When tourists obtain emotional satisfaction through symbolic consumption, the premium ability of tourism commodities will be enhanced and the derivative value of tourism will thus be formed. Therefore, excavation and utilization of symbol consumption is the core factor of sustainable tourism construction.

Authors: Lu Hui , Liu Liuqingqing
Published: April 2021

In recent years, microplastics (MPs) pollution have become a global environmental issue, which aroused concern about their potential toxicity to marine organisms. However, due to the gradual depletion of natural resources, it had been rapidly developed in aquaculture. Therefore, this article studied the effect of polystyrene (PE) on the growth of Paralichthys Olivaceus. The surface of PE was rough and average size was 197.3 ± 11.2 μm. The contact angle of PE was 100.3 ± 2.5 °, which indicated that PE had a hydrophobic surface. PE exposure had no significant effect on the body length growth of fish, but compared with CK treatment, the weight growth of fish in PE treatment group was slower, which increased by 36.3% on the 28th day, but only increased by 10.9% in PE treatment group, indicating that PE could inhibit the growth of fish. PE led to the decrease of oxygen consumption rate of fish. On the 7th, 21st and 28th day, the oxygen consumption rate of fish decreased by 7.9%, 25.4% and 41.1%, respectively. Based on the above results, we concluded that marine MPs could inhibit the growth of the benthic economic fish, which would disturb the balance of the marine ecosystem.

Published: April 2021

Antibiotics, a type of emerging contaminants in marine environment, have posed serious threats to human health and ecological function. Biochar has been widely used in the remediation of multiple pollutants due to low cost and good adsorption characteristics. However, the adsorption characteristics of biochar for antibiotics in seawater are still unclear. Therefore, a coconut shell activated carbon (AC) and a sludge biochar produced at 700 °C (SB700) were selected to carry out batch adsorption experiments of sulfamethoxazole (SMX) under different adsorbent dosage and different initial concentration of SMX. These results showed that the maximum removal rate (R) of AC and SB700 was 99.9% and 97.9%, the maximum adsorption capacity (Qe) was 13.7 mg g-1and 1.6 mg g-1, and the maximum adsorption coefficient (Kd) was 2142 L g-1and 5.1 L g-1, respectively. Compared with SB700, AC showed the excellent performance in SMX adsorption. This study provided theoretical support and experimental basis for the development of highly efficient antibiotic adsorbents in marine ecosystem.

Open government affairs (OGA) play an important role in promoting national governance system and capacity. In order to realize an open and efficient government, it is necessary to scientifically evaluate the performance of government. The effect of OGA can be improved continuously through the feedback from evaluation, which is beneficial for the sustainable development of OGA. However, with the continuous development of OGA, the existing methods of evaluation are faced with such problems as poor-timeliness, high-cost and subjective uncertainty, which are difficult to satisfy the demands of performance evaluation of OGA. Therefore, this paper puts forward a performance evaluation method based on T-S fuzzy neural network. Our method has a strong ability of data processing, which can simplify the work flow. The T-S fuzzy neural network was trained and tested through using the performance evaluation data of all districts and counties in Shandong Province, China. Finally, the evaluation results offered by our method are highly accurate. Hence, our method is suitable for the performance evaluation of OGA, it can continuously enhance the improvement of government’s performance management and capacity building so as to promote the sustainable development of OGA.

Authors: Gao HuaJian , Mou NaiXia
Published: April 2021

With the further advent of the era of big data, the scale of social media data containing geolocation information is exploding, providing a new source of big data information and perspective for an in-depth study of the changing spatio-temporal and geographical characteristics of the current tourist population. This paper extracts data on popular attractions in the Tibet Autonomous Region using the HDBSCAN algorithm combined with the TF-IDF algorithm based on information on images with geotags shared by users in the Flickr image sharing site from 2005-2018. Social network analysis was used to explore the changes in the spatial and temporal characteristics of inbound tourism flows in Tibet. The results show that: (1) in terms of temporal characteristics, the number of inbound tourists shows obvious off-peak seasons, with relatively high sensitivity to the influence of economic, policy and infrastructure construction factors; (2) in terms of spatial distribution characteristics, the inbound tourism flow in Tibet shows an “axis-scattered” distribution. The core area is centred on Lhasa and extends in three directions: west, north and east along important roads.

Published: April 2021

Using data from Chinese A-share listed companies in tourism related industries from 2009 to 2018, this paper examines the influence of institutional investor shareholdings on corporate social responsibility (CSR) performance. Results show that: First, institutional investor shareholdings can significantly improve CSR performance of tourism related public companies in China. After implementing robustness test, this positive relationship remains solid. Second, the positive effect of institutional investor shareholdings is significantly unbalanced regarding different CSR dimensions, with the most salient influence in promoting companies’ social welfare contributions. And third, the impact of institutional investor shareholdings can be strengthened when listed companies are ultimately controlled by the state.
