Yet, little is known about what happens after co-production and whether and how co-produced knowledge scales up. This article focuses on climate-driven decision support tools co-produced by researchers, farmers and agricultural advisers in the US Midwest. Through two surveys (N = 5,393) with farmers and agricultural advisers, it examines how engagement and marketing campaigns to disseminate the tools influenced their use. Here we find that beyond the highly iterative co-production process, other forms of user interaction such as outreach engagement and marketing campaigns are critical to scale up the impact of co-produced knowledge. Positively, we also show that most surveyed farmers and advisers who were not involved in the engagement phase reported having their needs met by the co-produced tools and were using, considering using or willing to recommend the climate-driven decision support tools. Hence, while co-production alone does not guarantee dissemination, it does increase knowledge fit and use. Dissemination for mass use, however, might require a committed effort from researchers and funders to promote and evaluate use post co-production to better understand societal impact and the role of co-produced knowledge in addressing sustainability problems.\nMarketingDirect Mail • EmailEngagementPromotion150+ Outreach events5 web-based C-DSTsCo-productionIdentification of needsInteractive tooland prioritiesdevelopmentSurveys • Focus groupsUser testing\n2.

Big data insights into urban park use in the pandemic: Changes in visitation patterns and exacerbated social inequalities in the U.S. Cities, 152, 105204. https://doi.org/10.1016/j.cities.2024.105204\n城市公园对于维护健康、宜居和可持续的城市至关重要。确保城市公园平等地服务于所有社区，特别是在疫情期间以及对于传统弱势群体而言，尤为重要。本研究探讨了新冠疫情如何改变了城市居民访问城市公园的模式，并评估了疫情是否加剧了美国不同社会人口群体在获取城市公园资源方面的不平等。我们从来源地和目的地两个方面调查了城市居民的访问模式，并采用了大数据方法，整合了移动设备的位置移动数据、遥感/地理空间数据、社会经济数据等。研究发现，与大流行前（即2019年）相比，疫情期间（即2020年和2021年）城市居民更倾向于访问那些更偏远、面积更大、绿化更好、人群更不密集、噪音更少且人类活动较少的城市公园。我们的结果还突出表明，疫情加剧了城市公园获取方面的社会不平等。来自种族/族裔少数群体比例更高、失业率和贫困率更高、收入更低的街区群体的城市居民，受到疫情的负面影响更大，去城市公园的可能性更低。更重要的是，与2020年疫情初期相比，这种社会不平等在2021年进一步加剧。\nUrban parks are essential to maintaining healthy, livable, and sustainable cities. It is vital to ensure urban parks serve the communities equally, particularly during the pandemic and for traditionally disadvantaged groups. This study examined how the COVID-19 pandemic changed urban dwellers' visitation patterns to urban parks and assessed whether the pandemic exacerbated the inequalities of urban park access among different sociodemographic groups in the U.S. We investigated urban dwellers' visitation patterns from two aspects (origin and destination) and used a big data approach by integrating mobility data from mobile devices, remote sensing/geospatial data, socioeconomic data, etc. This study found urban dwellers preferred visiting urban parks that were remoter, larger, greener, less crowded, less noisy, and with less human activities during the pandemic (i.e., 2020 and 2021) vs. pre-pandemic (i.e., 2019). Our results also highlighted that the pandemic exacerbated social inequalities in urban park access. The urban dwellers from block groups with higher percentages of racial/ethnic minorities, higher unemployment and poverty rates, and lower income were more negatively influenced by the pandemic and became less likely to visit urban parks. More importantly, such social inequalities further increased in 2021 compared with the early pandemic period of 2020.\n3. Lu, J., Ranjan, P., Floress, K., Arbuckle, J. G., Church, S. P., Eanes, F.

Because farming systems and farmers' values and attitudes are heterogeneous, factors that consistently predict conservation behaviors remain elusive. Moreover, heterogeneity is present among studies regarding the type of CPs examined, and whether behavioral intentions or actual behaviors were measured. This study considers the characteristics of each CP, and whether a given study measured behavioral intention or actual behavior, to better understand farmers' adoption of CPs.
