8 pages, Public perception about the reality of climate change has remained polarized and propagation of fake information on social media can be a potential cause. Homophily in communication, the tendency of people to communicate with others having similar beliefs, is understood to lead to the formation of echo chambers which reinforce individual beliefs and fuel further increase in polarization. Quite surprisingly, in an empirical analysis of the effect of homophily in communication on the level of polarization using evidence from Twitter conversations on the climate change topic during 2007–2017, we find that evolution of homophily over time negatively affects the evolution of polarization in the long run. Among various information about climate change to which people are exposed to, they are more likely to be influenced by information that have higher credibility. Therefore, we study a model of polarization of beliefs in social networks that accounts for credibility of propagating information in addition to homophily in communication. We find that polarization can not increase with increase in homophily in communication unless information propagating fake beliefs has minimal credibility. We therefore infer from the empirical results that anti-climate change tweets are largely not credible.

21 pages., Credibility is particularly important in organic food systems because there are only marginal visual and sensorial differences between organic and conventionally produced products, requiring consumers to trust in producers’ quality claims. In this article I explore what challenges the credibility of organic food systems and I explore how credibility of organic food systems can be maintained, using the Danish organic food system as a case study. The question is increasingly relevant as the sale of organic food is growing in Denmark as well as globally, and consumers’ expectations of organics continuously evolve. The inquiry is threefold, first I outline a conceptual framework for understanding trust and credibility in the food system, secondly I explore the developments in Danish organic food systems and thirdly discuss the challenges and opportunities for maintaining trust in the Danish organic food system. In the analysis I indicate eight key challenges: (1) unrealistic expectations, (2) blind trust and little motivation for extending their knowledge, (3) consumers assess the overall credibility of organic products, (4) ambitious ethical principles, (5) new consumer groups introduce new expectations, (6) frozen requirements in a changing world, (7) growing imports and labelling and (8) multiple versions of organics and the diversity is growing, as well as four aspects which may maintain the credibility of organics if implemented: (1) coordinate expectations, (2) communicate requested information, (3) institutional reform and (4) open communication of pros and cons of organic production.

4 pages., Online from publisher website., Perspectives about how consumers will perceive technology in food and agriculture going forward. "...will they view innovation as positive and something they should embrace and support? Or, will innovation be perceived as another looming threat that should be avoided at all costs? The answer to those questions rests with those who bring the technology to market."
