A business model basically describes the way a company makes money. Yet, often we use digital services for free (e.g. Facebook, Google or WhatsApp) or for what seems to be a relatively minor price (e.g. Blablacar, Airbnb, and Amazon). Digital business models are different to traditional business models. Digital Business Models explains the key challenges and characteristics of the various business models that are used by digital businesses. These companies can be a source of inspiration for traditional bricks-and-mortar companies that aim to go digital and/or revamp their traditional business model. Most businesses rely on some form of digital technology for their marketing communication, customer relationship management, supply chain or distribution, yet digital transformation entails a complete reassessment of the way value is created and captured. Digital Business Models details the successful customer acquisition tactics and the development of business ecosystems by digital players. Using the relevant academic and managerial body of knowledge, the authors define the concepts, describe the various ways digital businesses create and capture value and propose some useful tools for managers to analyse a situation, formulate or implement a strategy. Different digital business types are evaluated, such as multisided platforms, digital merchants, subscription-based model, freemium, social media and sharing economy. Each chapter is illustrated with several examples and the appendix comprises four full-length case studies.

The digital agriculture revolution holds a promise to build an agriculture and food system that is efficient, environmentally sustainable, and equitable, one that can help deliver the Sustainable Development Goals. Unlike past technological revolutions in agriculture, which began on farms, the current revolution is being sparked at multiple points along the agrifood value chain. The change is driven by the ability to collect, use, and analyze massive amounts of machine-readable data about practically every aspect of the value chain, and by the emergence of digital platforms disrupting existing business models. All this allows for drastically reduced transaction costs and pervasive information asymmetries that plague the agrifood system. The success of the digital transformation, however, is not guaranteed as the risks it brings are numerous, including those related to data governance and inadequate competition within and between digital platforms. What's Cooking: Digital Transformation of the Agrifood System investigates how digital technologies can accelerate the transformation of the agrifood system by increasing efficiency on the farm; improving farmers' access to output, input, and financial markets; strengthening quality control and traceability; and improving the design and delivery of agriculture policies. It also identifies a key role for the public sector in maximizing the benefits of this process while minimizing its risks, through enabling an innovation ecosystem featuring open datasets, digital platforms, digital entrepreneurship, digital payment systems, and digital skills and encouraging equitable technology adoption.

Point of Sale offers the first significant attempt to center media retail as a vital component in the study of popular culture. It brings together fifteen essays by top media scholars with their fingers on the pulse of both the changes that foreground retail in a digital age and the history that has made retail a fundamental part of the culture industries. The book reveals why retail matters as a site of transactional significance to industries as well as a crucial locus of meaning and interactional participation for consumers. In addition to examining how industries connect books, DVDs, video games, lifestyle products, toys, and more to consumers, it also interrogates the changes in media circulation driven by the collision of digital platforms with existing retail institutions. By grappling with the contexts in which we buy media, Point of Sale uncovers the underlying tensions that define the contemporary culture industries.

Management of water resources in large rivers basins typically differs in important ways from management in smaller basins. While in smaller basins the focus of water resources management may be on project implementation, irrigation and drainage management, water use efficiency and flood operations; in larger basins, because of the greater complexity and competing interests, there is often a greater need for long-term strategic river basin planning across sectors and jurisdictions, and considering social, environmental, and economic outcomes. This puts a focus on sustainable development, including consumptive water use and non-consumptive water uses, such as inland navigation and hydropower. It also requires the consideration of hard or technical issues—data, modeling, infrastructure—as well as soft issues of governance, including legal frameworks, policies, institutions, and political economy. Rapidly evolving technologies could play a significant role in managing large basins. This Special Issue of Water traverses these hard and soft aspects of managing water resources in large river basins through a series of diverse case studies from across the globe that demonstrate recent advances in both technical and governance innovations in river basin management.
