This book demonstrates how agriculture can play a determining role in integrated, climate-optimised urban development. Agriculture within urban growth centres today is more than an economic or social left-over or a niche practice. It is instead a complex system that offers multiple potentials for interaction with the urban system. Urban open space and agriculture can be linked to a productive green infrastructure – this forms new urban-rural linkages in the urbanizing region and helps shape the city. But in order to do this, agriculture has to be seen as an integral part of the urban fabric and it has to be put on the local agenda.Urban Agriculture for Growing City Regions takes the example of Casablanca, one of the fastest growing cities in North Africa, to investigate this approach. The creation of synergies between the urban and rural in an emerging megacity is demonstrated through pilot projects, design solutions, and multifunctional modules. These synergies assure greater resource efficiency; particularly regarding the use and reuse of water, and they strengthen regional food security and the social integration of multiple spheres. A transdisciplinary research approach brings together different scientific disciplines and local actors into a process of integrated knowledge production. The book will have a long lasting legacy and is essential reading for researchers, planners, practitioners and policy makers who are working on urban development and urban agricultural strategies.

Liquid multiphase processes represent a promising option for realizing novel, efficient, and sustainable production processes, as required for the transformation towards climate-neutral manufacturing processes. This volume presents the results obtained over twelve years in the DFG-funded collaborative project Transregio 63 “Integrated Chemical Processes in Liquid Multiphase Systems”. In an interdisciplinary approach to the design and operation of such processes, essential principles of Green Chemistry are realized, such as using long-chain olefins as model representatives of renewable raw materials, highly effi cient catalysts, and green solvents, linked with process optimization to improve energy and material efficiency. Experts from different fields addressed all steps of the development process, from the description of the reactions on the molecular level via thermodynamics and the design of efficient separation processes to the operation of entire miniplants for liquid multiphase production processes. Thus, the complete development chain from the first reaction-related investigations in the laboratory to the technological realization in miniplants with model-based control is demonstrated. Numerous methodological innovations are proposed and validated using several innovative phase systems (thermomorphic multiphase systems, microemulsion systems, Pickering emulsions) and homogeneously catalyzed reactions. Engineers and chemists from the chemical industry as well as advanced students and researchers will get valuable insights into the physico-chemical phenomena in chemical multiphase processes and benefit from recommendations concerning methods for the selection of phase systems and rapid model-based process development.

Transportvorgänge spielen eine überragende Rolle in verfahrenstechnischen Prozessen, die in unterschiedlichen Industriezweigen – speziell in der chemischen, pharmazeutischen und der Lebensmittelindustrie sowie in der Biotechnologie – die Basis der Produktherstellung bilden. Das fundamentale Verständnis von Transportvorgängen ist eine unverzichtbare Voraussetzung für diejenigen, die diese in technischen Prozessen umsetzen. Dazu zählen vorrangig Ingenieure unterschiedlicher Fachdisziplinen, technische Chemiker und Biotechnologen. In der Neuauflage enthält das Buch neben der umfassenden Darstellung der grundlegenden Gesetzmäßigkeiten deren methodische Anwendung in vielfältigen technischen Prozessen. Die praktische Umsetzung kann anhand von 200 Übungsaufgaben im Selbststudium oder mit einem separaten Lösungsbuch vertieft werden. Studierende und Praktiker sollen mithilfe dieses wahlweise Nachschlagewerks oder Lehrbuchs in die Lage versetzt werden, eigene spezifische Aufgaben zu analysieren und zu bewältigen.
