Book Synopsis Deficit Irrigation Practices by : Food and Agriculture Organization of the United Nations
Download or read book Deficit Irrigation Practices written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Actual Crop Water Use in Project Countries by : Robina Wahaj
Download or read book Actual Crop Water Use in Project Countries written by Robina Wahaj and published by World Bank Publications. This book was released on 2007 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report aims to synthesize the results of a crop water use study conducted by country teams of the GEF/World Bank project, Regional Climate, Water, and Agriculture: Impacts on and Adaptation of Agro-ecological Systems in Africa. It also presents the results of the second phase of the study based on climate change scenarios, conducted by the South Africa country team. The actual evapotranspiration of five commonly grown crops-maize, millet, sorghum, groundnuts, and beans-in two selected districts were analyzed by six country teams. In addition, two country teams also analyzed other crops grown in the districts. The regional analysis shows that the actual yield of the different crops-specifically of maize and groundnuts-improves with an increase in actual evapotranspiration, although the gap remains wide between actual and potential yield and actual and maximum evapotranspiration, especially for the rainfed crops. This highlights the importance of improved water management if agriculture is to play an important role as a source of food security and better livelihoods. The report highlights the vulnerability of maize to water stress and the increased risks to the viability of rainfed farming systems based on this crop. The results of the second phase of analysis show that a 2°C increase in the temperature and a doubling of carbon dioxide concentration in the atmosphere will shorten the growing period of maize, which will result in decreased crop water requirement and use. The authors recommend extending this type of analysis to other crops as well as to other countries to develop a clearer picture of the changing pattern in crop water use of the major crops grown in the project countries.

Book Synopsis Proceeding of the 3rd International Conference on Social Knowledge Sciences and Education (ICSKSE) 2023"Change and Continuity in Southeast Asia" by : Aditya Nugroho Widiadi
Download or read book Proceeding of the 3rd International Conference on Social Knowledge Sciences and Education (ICSKSE) 2023"Change and Continuity in Southeast Asia" written by Aditya Nugroho Widiadi and published by Springer Nature. This book was released on 2024-01-27 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an open access book. Socio-culturally, people in the Southeast Asian region have a heterogeneous composition. This diversity can be seen from the large number of ethnic compositions that inhabit the region. For example, in Indonesia, there are already various ethnic groups, not yet to mention in other regions such as Malaysia, Philippine, and others. The diversity of these ethnic groups is directly proportional to the variety of languages that exist in Southeast Asia. Similarly with the languages, the culture in these ethnic groups is definitely diverse. Interestingly, this diversity is constantly changing, keeping up with the global changes. These changes are important to study, in order to get an overview of the socio-cultural changes and continuity that currently exist in the Southeast Asian region. The various changes and continuity that occur historically, geographically, and socio-culturally mentioned above, will also have various impacts on the educational aspect. Therefore, it is also pivotal to examine the various change and continuity that occur in the field of education of Southeast Asia. This is because the field of education will determine where Southeast Asia will be taken in the future.

Book Synopsis Water Resources Management and Reservoir Operation by : Ramakar Jha
Download or read book Water Resources Management and Reservoir Operation written by Ramakar Jha and published by Springer Nature. This book was released on 2021-09-20 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores many recent techniques including ANN, fuzzy logic, hydraulic models and IWRM utilized for integrated water resources management, a real challenge in India for obtaining high irrigation efficiency. The book deals with topics of current interest, such as climate change, floods, drought, and hydrological extremes. The impact of climate change on water resources is drawing worldwide attention these days; for water resources, many countries are already stressed and climate change along with burgeoning population, rising standard of living, and increasing demand are adding to the stress. Further, river basins are becoming less resilient to climatic vagaries. Fundamental to addressing these issues is hydrological modelling which is covered in this book Further, integrated water resources management is vital to ensure water and food security. Integral to the management is groundwater and solute transport. The book encompasses tools that will be useful to mitigate the adverse consequences of natural disasters.

Book Synopsis Developments in Soil Classification, Land Use Planning and Policy Implications by : Shabbir A. Shahid
Download or read book Developments in Soil Classification, Land Use Planning and Policy Implications written by Shabbir A. Shahid and published by Springer Science & Business Media. This book was released on 2013-02-15 with total page 875 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world’s population continues to expand, maintaining and indeed increasing agricultural productivity is more important than ever, though it is also more difficult than ever in the face of changing weather patterns that in some cases are leading to aridity and desertification. The absence of scientific soil inventories, especially in arid areas, leads to mistaken decisions about soil use that, in the end, reduce a region’s capacity to feed its population, or to guarantee a clean water supply. Greater efficiency in soil use is possible when these resources are properly classified using international standards. Focusing on arid regions, this volume details soil classification from many countries. It is only once this information is properly assimilated by policymakers it becomes a foundation for informed decisions in land use planning for rational and sustainable uses.
