Nearly three decades after the dawn of democracy, South Africa has remained a country of 'two agricultures'. On the one hand we have a subsistence, primarily non-commercial, black farming segment. On the other hand, however, we have a predominantly commercial and white farming sector that is well-resourced and has access to domestic and international trade networks. These disparities can be traced back to South Africa's painful history where, for decades, black farmers were on the margins of government support and also experienced land dispossession and livestock plunder. A Country of Two Agricultures focuses less on history and more on the present and the future, explaining why these disparities have persisted in the democratic era, and what it will take to overcome them. It aims to contribute to a better understanding of the variety of agricultural forces, taking into account both questions of domestic political economy and external factors, as well as to bring to light new risks and opportunities. Wandile Sihlobo offers insights into the role of agriculture in the South African economy from an agricultural economy perspective, and provides political economy insights that are rooted in the experiences of farming communities on the ground and right through the value chain. Beyond insights on the realities this book offers the government, the private sector, and anyone interested in the betterment of the South African economy, tools to grapple with this duality, and proposes a framework for bolstering the black farming segment for growth and competitiveness – and ultimately food security. Wandile Sihlobo is the Chief Economist of the Agricultural Business Chamber of South Africa (Agbiz) and the author of Finding Common Ground: Land, Equity and Agriculture.Voir livre
Today there is no place on Earth that does not harbor invasive exotic species. Invasive plants and animals can be found on every continent, including Antarctica, and within all waterbodies, including all oceans. In our increasingly connected world, with speedy commercial and recreational travel and the global movement of biological matter for food, invasive species are showing up at such a fast rate that there is no way to accurately count how many currently exist or how many are likely to emerge in the coming decades. Monitoring these species and controlling their spread is essential, as we increasingly understand the negative impacts they pose: their threat to our health; the toll they take on our commercial production; and the threat they pose to native ecosystems. This Very Short Introduction provides a clear definition of an invasive species, and considers the myriad ways they are moved around the globe, and the ecological, social, and economic impacts they often impose. Exploring the way Earth's biodiversity is being affected by global change, Julie Lockwood also discusses policy and management approaches to combating the ill-effects of invasive species, and how invasive species fit within the broader context of environmental change.Voir livre
Human-Computer Interaction (HCI) is a multidisciplinary field that focuses on the design and use of computer technology, particularly the interfaces through which humans interact with computers. As technology has evolved, so too has the interaction between users and machines, and understanding this relationship is crucial for creating systems that are not only functional but also intuitive and user-friendly. At the heart of HCI is the goal of improving the interaction between users and computers to ensure usability, efficiency, and satisfaction. The concept of HCI emerged as computing technology became more widely accessible and user-centric design became a necessity. Early computers were primarily operated by specialists, and the interface was often limited to text-based inputs and outputs. However, as computers evolved to serve a broader audience, the need for more sophisticated and user-friendly systems became clear. This led to the development of graphical user interfaces (GUIs), which are now commonplace in many computing environments, making interaction with technology more intuitive and visually engaging. HCI as a field draws from various disciplines such as computer science, psychology, design, and ergonomics. The key principles in HCI are centered on understanding how users interact with technology, what their needs and preferences are, and how technology can be designed to meet those needs. At the same time, it focuses on the efficiency, effectiveness, and satisfaction that the interaction can provide. This involves studying human cognition, behavior, and the way people process information to ensure that systems are designed in ways that align with natural human capabilities.Voir livre

String theory is a theoretical framework aiming to unify all fundamental forces and particles by positing that they are vibrations of one-dimensional "strings," rather than point-like particles. These strings, in different vibrational modes, correspond to various particle types and properties. Key to string theory is the requirement of extra dimensions—beyond the familiar three spatial and one temporal dimension—that are typically compactified into small, curled-up spaces. These extra dimensions are crucial for the theory's mathematical consistency and to reconcile gravity with the other fundamental forces. Central to its complexity are Calabi-Yau manifolds, complex multidimensional spaces used in the compactification process, influencing observable universe properties. Despite its potential to provide a unified framework for all physics forces, string theory faces challenges including mathematical intricacies, the lack of direct experimental verification, and numerous variant formulations.Voir livre
