European cropping systems are often characterized by short rotations or even monocropping,leading to environmental issues such as soil degradation,water eutrophication,and air pollution including greenhouse gas emissions,that contribute to climate change and biodiversity *** use of diversification practices(i.e.,intercropping,multiple cropping including cover cropping and rotation extension),may help enhance agrobiodiversity and deliver ecosystem services while developing new value *** its benefits,crop diversification is hindered by various technical,organizational,and institutional barriers along value chains(input industries,farms,trading and processing industries,retailers,and consumers)and within sociotechnical systems(policy,research,education,regulation and advisory).Six EU-funded research projects have joined forces to boost crop diversification by creating the European Crop Diversification Cluster(CDC).This Cluster aggregates research,innovation,commercial and citizen-focused partnerships to identify and remove barriers across the agrifood system and thus enables the uptake of diversification measures by all European value-chain *** CDC will produce a typology of barriers,develop tools to accompany actors in their transition,harmonize the use of multicriteria assessment indicators,prepare policy recommendations and pave the way for a long-term network on crop diversification.

The EIP-Agri multiactor approach was exemplified during a 3-day workshop with 63 project participants from the EU H2020 funded project“Redesigning European cropping systems based on species MIXtures”.The objective was to share firsthand experience of participatory research among researchers who were mostly not familiar with this *** participants were divided into smaller multidisciplinary groups and given the opportunity to interact with representatives from eight actor positions in the value chain of the agrifood cooperative Terrena located in Western *** four stages of the workshop were:(1)key actor interviews,(2)sharing proposed solutions for overcoming barriers,and(3)developing possible interdisciplinary *** of frustration were recorded serving both as a motivation for group members to become more aware of the scientific concerns and practices of their colleagues,as well as a recognition that some researchers have better skills integrating qualitative approaches than ***,the workshop format was an effective way to gain a common understanding of the pertinent issues that need to be addressed to meet overall multiactorapproach *** with the actor networks was identified and emphasized as a means to overcome existing barriers between academia and practice in order to coproduce a shared vision of the benefits of species mixture benefits.

在砖瓦的行业里我们把隧道窑定义为一个可连续烧结砖瓦产品的焙烧设备，而热/冷空气则与制品移动方向相反的方向运行。隧道窑的两个主要的优势在于：①利用循环气体在冷却和烧结的产品之间传递热量，从而减少燃料消耗；②通过动态的过程增加产能。主要的缺点在于这样的窑炉不易被停止和重启。鉴于1kg的空气和1kg的黏土及页岩具有相同的比热（分别是0.24和0.22kcal/kg/C）,我们可以得出这样的结论：一个完美的隧道窑，约1kg单向运行的空气可以冷却1kg反向运行的产品。
