The role of collaborations in the development and implementation of sustainable livestock concepts in The Netherlands

This paper discusses the role of collaborations in the development and implementation of sustainable livestock farming. The study reflects upon the experiences with two innovative pig farming concepts in the Netherlands that aim to address sustainability-related concerns regarding the economic viability, environmental impact and social responsibility of livestock production. The findings show that collaborations can result in smarter and innovative solutions and provide support in the development of more sustainable farming concepts. The study also shows that collaborations do not safeguard the implementing of these concepts in practice. Pioneers are confronted with higher production costs and the complex context of agricultural policies and regulations. These pioneering efforts are, however, the seeds for change, and the key ingredient for a transition towards more sustainable production. We rely upon their innovations, social networks and learning experiences in the transition towards more sustainable production. Therefore, pioneers need to be protected from market influences and regulatory barriers, and supported by intermediaries when developing novelties for a more sustainable agriculture. The findings emphasize the need for more knowledge exchange and understanding between farmers, policy-makers and researchers to navigate towards a more sustainable agriculture in the future.     

中国生猪价格周期性波动分析、展望及对策

2006年以来,中国生猪价格波动经历了三个半周期,呈现出价格波动周期日益延长、价格波动幅度前窄后宽、传统消费旺季作用逐渐消退等特征。其中既有生猪养殖自身规律、规模化养殖比例提升等内因的影响,也有上游行业价格变动、生猪疫情等外因的影响。综合来看,2019年非洲猪瘟疫情发展、规模化生猪养殖场补栏、气温条件变化及冬季的猪肉旺季消费等情况会对后续的生猪价格波动走势产生较大影响,至2020年春节前生猪价格持续走高。应通过加快生猪养殖产业结构升级、加强生猪市场信息服务体系建设、推进生猪产业链市场化发展等措施,有效减缓中国生猪价格周期波动的影响。     

Disaggregating and reaggregating work: Workers,management and the struggle over creating coherency and purpose in a context of work degradation

The article argues that whilst there is a growing sense of degradation and worsening conditions (disaggregation) of work in the cleaning sector in general, there are some important contradictions which require complex organisational responses. In the main, there is a growing sense of isolation in this work, yet also a growing perception of autonomy and workers having to use discretion in new and challenging ways. This article focuses on these issues and management responses to reaggregate the nature of such work, creating new forms of identity and activities intended to enhance (or address) the levels of stability and sustainability at work as well as in operational processes. This management conundrum means that they need to deal with a range of job‐related, skill‐oriented worker learning and also representation issues. These responses bring to the fore the contested nature of such forms of work and how they are changing.
