The Gulf Cooperation Council (GCC) is a political and economic union of Arab states, namely Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the Unites Arab Emirates. The GCC was formed in 1981 to strengthen the members’ economic, social and political ties by harmonizing regulations in various fields including economy, finance, trade and customs. The region extends over a territory of 2 673 108 km2 and is home to about 50 million people. The common denominators of the GCC countries are limited natural fertile land, scarce water resources and harsh climate. Depending on the country, the agriculture sector may use as much as 75 percent of the national available water resources. This has enormous environmental costs and significantly affects the sustainability of overall development in the Arabian Peninsula.According to Al-Rashed and Sherif (2000), the lack of renewable water resources is one of the critical constraints to sustainable development in the GCC countries. Rainfall in the Arabian Peninsula is scarce and infrequent. Over-exploitation of fossil groundwater resources, mostly to meet irrigation demands and create greenery lands, has already affected the productivity of aquifers, both quantitatively and qualitatively, despite the fact that much of the freshwater demand in the GCC countries is already covered using desalinated water. Reducing water consumption and increasing water efficiency are essential to enhancing agriculture and moving towards increased self-sufficiency with the production of high-quality, safe and diversified foods in the GCC countries. Exploiting the full potential of protected agriculture should save significant amounts of water, which can be used not only for agriculture but for other needs as well.

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.

Protected cultivation - the safeguarding of crops from the harmful effects of climate change, environmentally toxic agricultural chemicals, and crop pests and diseases - is necessary for improving crop growth conditions. This new volume addresses this need by presenting valuable research on the components of protected cultivation, including climate control, modeling, automation, and economics. The volume offers comprehensive coverage of the many aspects of protected crop cultivation, including: selecting site-specific appropriate protected structures design, construction, and suitability of structures improved crop cultivation techniques (shifting from conventional to modern soil-less cultivation approaches) cropping sequence of vegetable crops irrigation and fertigation automation climate monitoring and management insect pests and diseases and their management greenhouse micro-climate/environments economic analysis of protected cultivation and more. The important information presented in this volume will be valuable for farming professionals, faculty and students in agricultural science, agricultural researchers and engineers, as well as for those involved in horticulture and floriculture.

This book focuses on pests (insect and mite) and diseases (fungal, bacterial, viral and nematode) in protected horticulture (fruits, vegetables and ornamentals) using physical, cultural, chemical, biological, host resistance, and integrated methods. It opens with chapters describing the setting in which integrated pest and disease control operates, i.e., the greenhouse and its environment. Subsequent chapters present the basic strategies and tactics of different control methods including integrated control, with special reference to greenhouse crops. Further chapters include the different facets of biological pest and disease control – its scientific bases, its development in practice, its commercialization and quality control. The concluding chapters of the book highlight the present status of integrated pest and disease control for the most important greenhouse crops (fruits, vegetables and flower crops) worldwide. The book’s final chapter explores future challenges for researchers assigned to identify non-pesticide methods and integrate sustainable pest management technologies that can contribute to increased productivity, such as breeding for durable resistance, biological control and devising integrated methods that will have minimal adverse environmental and social impacts. Among productivity-enhancing technologies, protected cultivation has a tremendous potential to increase the yield of vegetables and flower cro ps by several fold. Pests and diseases are one of the major challenges to protected cultivation. Year-round warm temperatures and relatively high humidity together with abundant food make the protected environment of greenhouses highly attractive to pests and diseases. Nevertheless, very little attention has been paid to the manipulation of greenhouse environments expressly to avoid disease epidemics and insect infestations, which together can easily account for 30% of crop losses. This book will be of immense value to all members of the scientific community involved in teaching, research and extension activities on protected horticulture. It also offers a useful reference guide for policymakers and practicing farmers, and can be used as a textbook for postgraduate courses.

The book consists of 32 chapters featuring the concepts and applications of precision farming and protected cultivation broadly covered with theoretical and practical approach. The first 8 chapters are exclusively designed to provide detailed information on concept, need, objectives, benefits, components, applications and limitations of precision farming; laser leveler and its working mechanism, components and functioning; mechanized sowing and types of mechanical seeders and their use; approaches for mapping of soils and plant attributes; site-specific weed and nutrient management; precision management of insect-pests and diseases; yield mapping in horticultural crops. An attempt has been made to cover the concept and application of protected cultivation in chapters from 9 to 30 characteristically highlighting the concept of greenhouse technology, its principles as well as historical and technological developments, agrivoltaic system, its concept and features, response of plant species under greenhouse conditions, criteria for the selection of crops and varieties for protected cultivation, basic considerations for site selection, orientation and designing of greenhouse structures, climate control mechanisms for cooling and heating in greenhouses, components, accessories and BIS codes for protected cultivation, types of Irrigation system for greenhouse production system, growing media for greenhouse cultivation, soil pasteurization namely solarization, steam sterilization, chemical sterilization and augmentation with biological agents, checking the suitability of soil and water for greenhouse crops, plug tray nursery raising, basics of fertigation in greenhouse production system, packages of practice for greenhouse cucumber, bell pepper, tomato and melons, potential of pruning as unconventional alternative for mass multiplication of greenhouse cucumber and tomato, types of soil-less cultures, GAP for protected cultivation and economic analysis of protected cultivation.

Mediterranean and West European pre-modern agriculture (agriculture before 1600) was by necessity ‘organic agriculture’. Crop protection is part and parcel of this agriculture, with weed control in the forefront. Crop protection is embedded in the medieval agronomy text books but specialised sections do occur. Weeds, insects and diseases are described but identification in modern terms is not easy. The pre-modern ‘Crop Portfolio’ is well filled, certainly in the Mediterranean area. The medieval ‘Pest Portfolio’ differs from the modern one because agriculture then was a Low External Input Agriculture, and because the proportion of cultivated to non-cultivated land was drastically lower than today. The pre-modern ‘Control Portfolio’ is surprisingly rich, both in preventive and interventive measures. Prevention was by risk management, intensive tillage, and careful storage. Intervention was mechanical and chemical. Chemical intervention used natural substances such as sulphur, pitch, and ‘botanicals’. Some fifty plant species are mentioned in a crop protection context. Though application methods look rather modern they are typically low-tech. Among them are seed disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated. The reality of pest outbreaks and other damages is explored as to frequency, intensity, and extent. Information on the practical use of the recommended treatments is scanty. If applied, their effectiveness remains enigmatic. Three medieval agronomists are at the heart of this book, but historical developments in crop protection from early Punic, Greek, and Roman authors to the first modern author are outlined. The readership of these writers was the privileged class of landowners but hints pointing to the exchange of ideas between them and the common peasant were found. Consideration is given to the pre-modern reasoning in matters of crop protection. Comparison of pre-modern crop protection and its counterpart in modern organic agriculture is difficult because of drastic changes in the relation between crop areas and non-crop areas, and because of the great difference in yield levels then and now, with several associated differences.
