Book Description
This book takes stock of micro irrigation systems (MIS), the technological intervention in India’s agricultural and water management sectors, over the past couple of decades. Based on empirical research from the major agriculturally dynamic states, viz., Gujarat, Rajasthan, Maharashtra, Tamil Nadu, Andhra Pradesh and Karnataka, the book provides a nuanced understanding and objective assessment of the implementation and adoption of MIS across these states. It addresses several of the questions related to adoption and impacts of MIS in India. On the adoption side, the key question that the book addresses is which segment of the farming community adopts MIS across states? The impacts analysed include those on physical, agronomic and economic aspects. At the macro level, the question being asked is about the future potential of MIS in terms of saving water from agriculture and making more water available for environment. The book also addresses the question of the positive/negative externalities and real social benefits and costs from the use of MIS, a major justification for heavy capital subsidies for its purchase by farmers. It also brings out certain critical concerns pertaining to MIS adoption, which need to be addressed through more empirical research based on longitudinal panel/ cross sectional data. The book would be of great use to researchers (agricultural water management, irrigation economics), students of water resource engineering, irrigation engineering and water resources management, as well as to policy makers and agricultural water management experts – national and international.

Book Description
Improving agricultural water use efficiency (WUE) is vitally important in many parts of the world due to the decreasing availability of water resources and the increasing competition for water between different users. Micro irrigation is an effective tool for conserving water resources. Studies have revealed a significant water savings, ranging from 40% to 70% under drip irrigation compared with surface irrigation. This new volume, Engineering Interventions in Sustainable Trickle Irrigation: Irrigation Requirements and Uniformity, Fertigation, and Crop Performance, presents valuable research that evaluates crop water and fertigation requirements, examines optimum irrigation and fertigation scheduling, and analyzes the performance of agricultural crops under micro irrigation. With an interdisciplinary perspective, this volume addresses the urgent need to explore and investigates the current shortcomings and challenges of water resources engineering, especially in micro irrigation engineering. The volume discusses crop water requirements, fertigation technology, and performance of agricultural crops under best management practices. The chapter authors present research studies on drip irrigated tomato, chilies, cucumber, eggplant, cabbage, garlic, sugarcane maize, cashew nut, sapota, banana, mango, and blueberries. Removing the research gap, this volume provides new information that will be valuable to those involved in micro irrigation engineering.
Protected agriculture, precision agriculture, and vertical farming: Brief reviews of issues in the literature focusing on the developing region in Asia

Book Description
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.
