The book will generate the useful information on various aspects such as growth of sprinkler irrigated area, cost of installation of sprinkler irrigation system, cost of cultivation, returns, net returns, return per rupee of investment, comparative profitability of different crops, farm level investment pattern on water conservation, role of credit, technical efficiency, factors affecting of the sprinkler irrigation system and factors affecting of the technical efficiency. The Book will be useful for farmers, academicians and researchers. It will also be helpful for government/ policy makers in developing future strategies for promoting the use of sprinkler irrigation system
This book presents a newly designed dynamic fluidic sprinkler (DFS) to improve hydraulic performance of the existing complete fluidic sprinkler (CFS) under low-pressure conditions. Sprinkler irrigation has high prospects for improving water management in crop production. In recent years, low-pressure water-saving has become an important research content in the field of sprinkler irrigation. It introduces the effect of riser height on rotation uniformity and application rate of the dynamic fluidic sprinkler. It also discusses the intelligent sprinkler irrigation technologies for autonomous and remote sensing system. This book will be a useful reference for researchers and professionals in the field of agriculture and irrigation.
Two of the greatest current challenges are climate change (and variability) and food security. Feeding nine billion people by 2050 will require major efforts aimed at climate change adaptation and mitigation. One approach to agriculture has recently been captured by the widely adopted term of "Climate Smart Agriculture" (CSA). This book not only explains what this entails, but also presents practical on-the-ground studies of practices and innovations in agriculture across a broader spectrum, including agroecology and conservation agriculture, in less developed countries. It is shown that CSA is not a completely new science and a number of its recommended technologies have been used for some time by local farmers all over the world. What is relevant and new is ‘the approach’ to exploit their adaptation and mitigation potential. However, a major limitation is the lack of evidence-based knowledge that is necessary for policy makers to prepare strategies for adaptation and mitigation. This book assembles knowledge of CSA, agroecology and conservation agriculture, and perspectives from different regions of the world, to build resilient food systems. The first part analyzes the concept, opportunities and challenges, and provides a global perspective, drawing particularly on studies from Africa and Asia. The second part of the book showcases results from various studies linked to soil, water and crop management measures from an ongoing program in India as well as experiences from other regions. The third section assesses the needs for an enabling policy environment, mainstreaming gender and sime final recommendations for up-scaling and/or out-scaling innovations.
This contributed volume describes management practices based on interdisciplinary and convergence science approaches from different disciplines of agricultural science to enhance the resilience of dryland agriculture. The main focus of this book is to address the current issues and trends along with future prospects and challenges in adopting salient agricultural management practices in drylands globally under a climate-change scenario. Climate change and global warming have profound repercussions on increasing frequency, severity, and duration of droughts and/or floods, which may have implications for future productivity of dryland agriculture, e.g., more water shortages or abundances and high or low runoff rates, diminished crop yields, and reduced water productivity. In past few years, many technological advancements and management strategies have been evolved to tackle the climate-induced risks of dryland agriculture considering interdisciplinary and convergence approaches that integrate knowledge from multi-disciplines. This book is an attempt to bridge the gap in literature by unraveling controversies and characteristics of dryland ecosystems under the changing climate and dealing with detailed procedures of applying the advanced practices adapted to climate change for management of dryland agriculture. This edited book is of interest to ecologists, economists, environmentalists, geologists, horticulturalists, hydrologists, soil scientists, social scientists, natural resource conservationists and policy makers dealing with dryland agriculture. This book offers a broad understanding of dryland agriculture and assists the reader to identify both the current as well as the probable future state of dryland agriculture in a global context.
As one of the eighteen field-specific reports comprising the comprehensive scope of the strategic general report of the Chinese Academy of Sciences, this sub-report addresses long-range planning for developing science and technology in the field of water science. They each craft a roadmap for their sphere of development to 2050. In their entirety, the general and sub-group reports analyze the evolution and laws governing the development of science and technology, describe the decisive impact of science and technology on the modernization process, predict that the world is on the eve of an impending S&T revolution, and call for China to be fully prepared for this new round of S&T advancement. Based on the detailed study of the demands on S&T innovation in China's modernization, the reports draw a framework for eight basic and strategic systems of socio-economic development with the support of science and technology, work out China's S&T roadmaps for the relevant eight basic and strategic systems in line with China's reality, further detail S&T initiatives of strategic importance to China's modernization, and provide S&T decision-makers with comprehensive consultations for the development of S&T innovation consistent with China's reality. Supported by illustrations and tables of data, the reports provide researchers, government officials and entrepreneurs with guidance concerning research directions, the planning process, and investment. Founded in 1949, the Chinese Academy of Sciences is the nation's highest academic institution in natural sciences. Its major responsibilities are to conduct research in basic and technological sciences, to undertake nationwide integrated surveys on natural resources and ecological environment, to provide the country with scientific data and consultations for government's decision-making, to undertake government-assigned projects with regard to key S&T problems in the process of socio-economic development, to initiate personnel training, and to promote China's high-tech enterprises through its active engagement in these areas.
In the contemporary world, unprecedented global events are challenging our ability to protect and enhance cultural heritage for future generations. Relevance and Application of Heritage in Contemporary Society examines innovative and flexible approaches to cultural heritage protection. Bringing together cultural heritage scholars and activists from across the world, the volume showcases a spectrum of exciting new approaches to heritage protection, community involvement, and strategic utilization of expertise. The contributions deal with a range of highly topical issues, including armed conflict and non-state actors, as well as broad questions of public heritage, museum roles in society, heritage tourism, disputed ownership, and indigenous and local approaches. In so doing, the volume builds upon, and introduces readers to, a new cultural heritage declaration codified during a 2016 workshop at the Royal Ontario Museum, Canada. Offering a clarion call for an enduring spirit of innovation, collaboration, education, and outreach, Relevance and Application of Heritage in Contemporary Society will be important reading for scholars, students, cultural heritage managers, and local community stakeholders.
