Fundamentals of irrigation and on-farm water management. Volume 1 / Volume 1

The book ́ Fundamentals of Irrigation and On-farm Water Management ́ (Volume 1) is a true textbook for the undergraduate students in Bio-Science Engineering, Agricultural Engineering, Water Resource Engineering, Civil & Environmental Engineering, Biological Systems Engineering, Environmental Science, Biological Sciences and Agricultural Sciences. The book deals with the fundamental aspects of irrigation development, climatic impact on crop production, irrigation requirement estimation, scheduling of irrigation, water measurement, water conservation & harvesting, and economic aspects of irrigation management. Understanding these processes leads to more rational and cost-effective decisions regarding irrigation planning, designing, and implementing irrigation & on-farm water management programs and projects, maintenance practices to maximize performance and reliability. The book ́ s objective is to present the fundamental principles of irrigation need assessment, water relations in the soil-plant-atmosphere continuum, and the principles needed to adopt the most appropriate approach toward irrigation development and management. The book presents the factors affecting the phenomena/parameter related to irrigation, exploring the relationship of irrigation need to the relevant factors, laboratory and field measurement procedures of their measurement (principles, background theory, and detail working methods). The content of this book provides the foundation to develop more appropriate irrigation design, and irrigation & water management. The book is equally useful for postgraduate students, engineers/practitioners and scientists in the relevant fields Content: Cover -- Fundamentals of Irrigation and On-farm Water Management: Volume 1 -- Foreword -- Preface -- Acknowledgements -- Contents -- Chapter 1: Introduction -- 1.1 Availability of Water in the Earth -- 1.2 Variability of Water with Time and Space -- 1.3 General Concept of Irrigation -- 1.3.1 Irrigation Scheduling -- 1.3.2 Full Irrigation -- 1.3.3 Deficit Irrigation -- 1.4 Global Outlook: World Population and World Water Use -- 1.4.1 Trend of World Water Use -- 1.5 Challenges and Opportunities in Irrigation and Water Management -- 1.5.1 Challenging Factors -- 1.5.2 Opportunities -- 1.6 Physiographic and Economic Factors Affecting Irrigation and Water Management: Case Study, Bangladesh -- 1.6.1 National Economy and Agriculture -- 1.6.2 Basic Physical Factors in Agricultural Production -- 1.6.3 Challenges and Limiting Factors in Agriculture in Bangladesh -- 1.6.4 Physical Features of Bangladesh Influencing Water Resources Utilization -- 1.6.5 Climate and Cropping Pattern -- 1.6.6 Major Source of Irrigation Water in Bangladesh and Concern of Sustainability -- 1.6.7 Considerations in Current Water-Starved Situations -- References -- Chapter 2: Fundamentals of Irrigation Development and Planning -- 2.1 Factors Affecting Farm Production -- 2.1.1 Agro-Ecological Factor/Constraint -- 2.1.2 Soil Factor -- 2.1.3 Hydrological Factor -- 2.1.4 Crop Factor -- 2.1.5 Water Management -- 2.1.6 Fertility Management -- 2.1.7 Socio-Economic Factor/Constraint -- 2.1.8 Other Management Factors -- 2.2 Important Factors Affecting Irrigation Planning and Development -- 2.2.1 Soil -- 2.2.2 Climate -- 2.2.3 Topography -- 2.2.4 Water Source -- 2.2.5 Crop(s) to be Cultivated -- 2.2.6 Energy -- 2.2.7 Labor -- 2.2.8 Capital -- 2.2.9 Commodity/Product Market -- 2.2.10 Economic Factor -- 2.2.11 Environmental Aspect -- 2.2.12 National Policy and Priority -- 2.2.13 Socio-Cultural Aspects -- 2.2.14 Institutional Infrastructure -- 2.3 Irrigation Development in Asia and Pacific Region -- 2.3.1 Progressive Irrigation Development in Bangladesh -- 2.3.2 Irrigation Development in China -- 2.3.3 Irrigation Development in Iran -- 2.4 Impact of Irrigation on Environment and Ecosystem -- 2.4.1 Positive Impacts -- 2.4.2 Negative Impacts -- 2.4.3 Degradation of Water Quality -- 2.4.4 Groundwater Abstraction -- 2.4.5 Water-Logging and Salinity -- 2.4.6 Health Risk -- 2.4.7 Simplification and Homogenization of the World180;s Ecosystem -- 2.5 Land Classification for Irrigation -- 2.5.1 Concept of Land Classification -- 2.5.2 Importance of Land Classification -- 2.5.3 Standards of Land Classification -- 2.5.4 Process of Land Classification -- 2.5.5 USBR Land Classification System -- Relevant Journals -- Relevant FAO Papers/Bulletins -- Questions -- References -- Chapter 3: Weather -- 3.1 Concept of Weather and Climate -- 3.2 Importance of Weather in Agriculture and Water Management -- 3.3 Basic Mechanisms of Weather Variability -- 3.3.1 Sun- Earth Geometry -- 3.3.2 Role of Monsoon Wind -- 3.3.3 Interaction Between Atmosphere, Ocean, and Land Surfaces -- 3.4 Weather Factors Determining/Influencing Crop Water Demand -- 3.4.1 Temperature -- 3.4.2 Humidity -- 3.4.3 Solar Radiation -- 3.4.4 Wind Speed -- 3.4.5 Sunshine Hour -- 3.5 Weather Elements Affecting Agriculture and Crop Productio. Agriculture is one of the few industries that has been creating resources conti- ously from nature. Sustainability of this industry is a crucial issue at now-a-days. Agricultural technologies are important to feed the growing world population. Agricultural engineering has been applying scienti?c principles for the optimal use of natural resources in agricultural production for the bene?t of humankind. The role of agricultural engineering is increasing in the coming days at the forthcoming challenges of producing more food with less water coupled with climate uncertainty. I am happy to know that a book entitled "Fundamentals of Irrigation and On-farm Water Management", written by Engr. Dr. M. H. Ali, is going to be p- lished by Springer. The book is designed to cover the major ?elds of agricultural and environmental engineering such as weather, plant, soil, water, and basics of on-farm water management. The book will be quite useful for the students of agricultural engineering. Students of other related branches of engineering s- ences, and engineers working in the ?eld and at research institutes will also be beni?ted. The book may serve as a text book for the students and as a practical hand-book for the practitioners and researchers in the ?eld of irrigation and on-farm water management. Utilization of the recent literature in the area and citation of relevant journals / reports have added a special value to this book. Considering the topics covered, engineers, scientists, practitioners, and educators will ?nd this book as a valuable resource.
