The frontiers of technologies have been constantly expanded in many industries around the world, including the agricultural sector. Among many “frontier technologies” in agriculture, are protected agriculture, precision agriculture, and vertical farming, all of which depart substantially from many conventional agricultural production methods. It is not yet clear how these technologies can become adoptable in developing countries, including, for example, South Asian countries like India. This paper briefly reviews the issues associated withthese three types of frontier technologies. We do so by systematically checkingthe academic articleslisted in Google Scholar, which primarily focus on these technologies in developing countries in Asia. Where appropriate, a few widely-cited overview articles for each technology were also reviewed. The findings generally reveal where performances of these technologiescan be raised potentially, based on the general trends in the literature. Where evidence is rich, some generalizable economic insights about these technologies are provided. For protected agriculture, recent research has focusedsignificantly on various features of protective structures (tunnel heights, covering materials, shading structures, frames and sizes) indicating that there are potentials for adaptive research on such structures to raise the productivity of protected agriculture. The research on protected agriculture also focuses on types of climate parameters controlled, andenergy structures, among others. For precision agriculture, recent research has focused on the spatial variability of production environments, development of efficient and suitable data management systems, efficiency of various types of image analyses and optical sensing, efficiency of sensors and related technologies, designs of precision agriculture equipment, optimal inputs and service uses, and their spatial allocations, potentials of unmanned aerial vehicles (UAVs) and nano-technologies. For vertical farming, research has often highlighted the variations in technologies based on out-door / indoor systems, ways to improve plants’ access to light (natural or artificial), growing medium and nutrient / water supply, advanced features like electricity generation and integration of production space into an office / residential space, and water treatment. For India, issues listed above may be some of the key areas that the country can draw on from other more advanced countries in Asia, or can focus in its adaptive research to improve the relevance and applicability of these technologies to the country.

This background paper to The State of Food Security and Nutrition in the World 2023 analyses a key element of agrifood systems transformation: the change of patterns in food supply and demand. Several studies have discussed this topic, but the current one takes an innovative perspective of analysis, considering these changes with a spatial perspective using the urban rural catchment areas (URCA) approach to analyse changes in food expenditure across the rural–urban continuum, using Living Standards Measurement Studies (LSMS) of 11 African countries. The analysis is preceded by a literature review of agrifood value chains transformation stages, drivers and current situation, focused in low- and middle-income countries (LMICs), and is followed by a macro review of food supply around the world and a “macro-meso” review of the supply of wheat and rice in two African countries. The conclusions shows that most food is purchased in all households across the rural–urban continuum, even in rural areas, breaking with the “myth” of rural subsistence farming in Africa. In addition, the results show a diffusion of the consumption of processed foods, including in a lesser extent highly processed foods, all across the rural–urban continuum, and not only in rural areas. From a food supply perspective, the low global availability of foods that are part of a healthy diet, as fruits, vegetables and legumes, nuts and seeds calls for increasing efforts for producing more nutritious foods in all countries of the world.

Precision agriculture (PA) involves the application of technologies and agronomic principles to manage spatial and temporal variation associated with all aspects of agricultural production in order to improve crop performance and environmental quality. The focus of this book is to introduce a non-specialist audience to the the role of PA in food security, environmental protection, and sustainable use of natural resources, as well as its economic benefits. The technologies covered include yield monitors and remote sensing, and the key agronomic principles addressed are the optimal delivery of fertilizers, water and pesticides to crops only when and where these are required. As a result, it is shown that both food production and resource efficiency can be maximized, without waste or damage to the environment, such as can occur from excessive fertilizer or pesticide applications. The authors of necessity describe some technicalities about PA, but the overall aim is to introduce readers who are unfamiliar with PA to this very broad subject and to demonstrate the potential impact of PA on the environment and economy.

Debates about public expenditure in the agricultural sector have reopened in many developing and emerging economies because of high budget deficits and changes in public opinion. As a result, agricultural policy in many of these countries is beginning to take a more market-oriented approach to agrarian problems, most notably through the introduction of contract farming. This book explores the policy issues around contract farming and its transformative potential and addresses the lack of empirical research on this topic by focusing on South Asia: principally India, Bangladesh and Nepal. The book first addresses the effects of contract farming (vertical coordination) on productivity, food security indicators (yield, consumption expenditures, prices), employment and input usage. Then it draws lessons from the South Asian case studies on the impact of institutional changes, like contract farming, on income and food security of smallholder households. The core of the book includes case study chapters on several commodities that are produced under contract farming, including vegetables and fisheries in Bangladesh, low-value crops in Nepal and coffee in India. Other chapters also explore contracts, storage, input usage and technical efficiency in these cases. This book serves as an essential guide to academics, researchers, students, legislative liaisons and think tank groups interested in agrarian issues, agricultural economics and agricultural policy in emerging economies and particularly in South Asia.

Each century has its own unique approach toward addressing the problem of high density and the 21st century is no exception. As cities try to cope with rapid population growth - adding 2.5 billion dwellers by 2050 - and grapple with destructive sprawl, politicians, planners and architects have become increasingly interested in the vertical city paradigm. Unfortunately, cities all over the world are grossly unprepared for integrating tall buildings, as these buildings may aggravate multidimensional sustainability challenges resulting in a “vertical sprawl” that could have worse consequences than “horizontal” sprawl. By using extensive data and numerous illustrations this book provides a comprehensive guide to the successful and sustainable integration of tall buildings into cities. A new crop of skyscrapers that employ passive design strategies, green technologies, energy-saving systems and innovative renewable energy offers significant architectural improvements. At the urban scale, the book argues that planners must integrate tall buildings with efficient mass transit, walkable neighbourhoods, cycling networks, vibrant mixed-use activities, iconic transit stations, attractive plazas, well-landscaped streets, spacious parks and engaging public art. Particularly, it proposes the Tall Building and Transit Oriented Development (TB-TOD) model as one of the sustainable options for large cities going forward. Building on the work of leaders in the fields of ecological and sustainable design, this book will open readers’ eyes to a wider range of possibilities for utilizing green, resilient, smart, and sustainable features in architecture and urban planning projects. The 20 chapters offer comprehensive reading for all those interested in the planning, design, and construction of sustainable cities.
