This collection features four peer-reviewed literature reviews on biodiversity management practices in agriculture. The first chapter reviews biodiversity management practices and benefits in Conservation Agriculture (CA) systems. After looking at the importance of soil microorganisms, the chapter looks at how CA systems contribute to soil biological activity, particularly the way cover crops and rotations, with a no-till regime, can enrich soil and the multitude or organisms living in it. The second chapter synthesizes and reviews the published information on grass hedges and their soil benefits, to better understand the potential of grass hedges for managing water erosion as well as improving soil health in agricultural lands. The third chapter reviews research on ways of modifying the agricultural landscape to reverse the decline in a range of fauna and flora. The chapter also reviews the characteristics and types of field margins, as well as their role in agroecosystems. The chapter concludes with a discussion on managing field margins to promote insect biodiversity and rare arable plant populations. The final chapter considers the impact of agricultural intensification on agricultural landscapes, farming systems and biodiversity. The chapter highlights how hedgerows can contribute to the multifunctionality of agroecosystems in intensively-managed agricultural landscapes, focussing on improved pest regulation and enhanced pollination services.

Rapid Industrialisation Coupled With Population Explosion Has Resulted In Greater Urbanisation. Because Of These, The Water That Was Available For Agriculture Is Now Being Shared By Various Sectors. This Has Resulted In A Gradual Decline In Per Capita Land And Water Availability. At The Same Time The Need To Increase The Food Production To Feed The Increasing Population Is Being Increasingly Felt. Mismanagement Of Available Water Has Added One More Dimension To This Problem Resulting In Development Of Problem Soils, Thus Causing Reduction In The Production Per Unit Quantity Of Water. Hence It Has Become Absolutely Necessary To Use The Available Water Resources In Such A Manner As To Get The Maximum Returns Per Unit Quantity Of Water. At Present No Book Covers The Multifaceted Nature Of This Problem. Hence In This Book All Aspects Like Methods Of Irrigation, Measurement Of Water, Quality Of Waters, Water Requirements Of Crops, Scheduling Of Irrigation, Water Budgeting, Irrigation Efficiency, Drainage, Recycling, Agronomy, Soil Science, Crop Physiological Aspects Of Irrigation System, Etc. Have Been Covered. A Separate Section Of Constraints And Weakness In The Current Water Management Practices Is Also Included In This Book.This Book Will Be Of Great Help To The Administrators Dealing With Water Management, Water Technologists, Scholars And Farmers Who Are Taking Steps To Maximise The Benefits Of The Available Water Resources On The Scientific Basis To Get The Higher Productivity Of Water.

In many countries irrigated agriculture consumes a large proportion of the available water resources, often over 70% of the total. There is considerable pressure to release water for other uses and, as a sector, irrigated agriculture will have to increase the efficiency and productivity of its water use. This is particularly true for manually operated irrigation systems managed by government agencies, which provide water for a large number of users on small landholdings and represent 60% of the total irrigated area worldwide. Drawing on the author's 30 years of experience in some 28 countries, this book offers knowledge of the management of irrigation and drainage systems, including traditional technical areas of systems operation and maintenance, and expanding managerial, institutional and organizational aspects. Chapters provide guidelines to improve management, operation and maintenance processes, which move management thinking out of traditional public-sector mindsets to a more customer-focused, performance-oriented service delivery. As a practical guide to improve efficiency and productivity in irrigated agriculture, this book will be essential reading for irrigation managers and technicians as well as students and policy makers in water management, agriculture and sustainable development.

This collection features four peer-reviewed literature reviews on soil erosion in agriculture. The first chapter identifies different types of soil degradation, focussing primarily on soil erosion by water. The chapter explores the impact of soil erosion processes on soil properties that relate directly to crop growth, including soil depth, water-holding capacity, carbon content and nutrient reserves. The second chapter reviews advances in techniques used to assess and measure soil erodibility by water, such as computer aided tomography. The chapter considers the role of static and dynamic soil properties in the erosion process, as well as the challenges that have developed as a result of climate change. The third chapter assesses the impact of heavy metal contamination on soil and its consequent role in the degradation of soil health. The chapter describes the sources, impacts, indicators and remediation of heavy metal contamination, as well as the development of improved soil management practices, including effective pollution control strategies. The final chapter discusses the implementation of integrated strategies under Conservation Agriculture (CA) farming systems to restore soil productivity in degraded agricultural lands in tropical and subtropical regions in Brazil. The chapter additionally considers the adoption of CA as a tool to prevent and reverse instances of soil degradation. What is an Instant Insight?

Water is critical to all human activities, but access to this crucial resource is increasingly limited by competition and the effects of climate change. In agriculture, water management is key to ensuring good and sustained crop yields, maintaining soil health, and safeguarding the long-term viability of the land. Water management is especially challenging on smallholder farms in resource-poor areas, which tend to be primarily rainfed and thus highly dependent on unreliable rainfall patterns. Sustainable practices can help farmers promote the development of soils, plants and field surfaces to allow maximum retention of water between rains, and encourage the efficient use of each drop of water applied as irrigation. Especially useful for farmers' groups, agricultural extension workers, NGOs, students and researchers working with farmers in dryland areas, this comprehensive yet concise book is a practical and accessible resource for anyone interested in sustainable water management.

In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.
