Book Synopsis More Crop Per Drop: Benchmarking On-farm Irrigation Water Use for Crop Production by : Katherine Elizabeth Boone Gibson
Download or read book More Crop Per Drop: Benchmarking On-farm Irrigation Water Use for Crop Production written by Katherine Elizabeth Boone Gibson and published by . This book was released on 2016 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient use of irrigation is essential to meet food production needs of growing global populations while ensuring long-term sustainability of freshwater resources. However, lack of on-farm irrigation data constrains understanding of irrigation variation and no framework exists to benchmark irrigation use using actual irrigation data. The following work investigates variation in irrigation using a database of ca. 1400 maize and soybean fields over 9 years in Nebraska and presents a framework to benchmark irrigation use using a separate database of ca. 1000 maize and soybean fields in Nebraska as proof of concept. "State-of-the-art" crop models estimated yield potential and irrigation water requirements for each field-year observation and were compared against producer-reported yield and irrigation. Precipitation and ETo accounted for >68% of observed year-to-year variation in irrigation in maize and soybean fields. Irrigation differed by ca.150 mm between regions due to differences in available water holding capacity. Weather and soils explained field-to-field variation in irrigation; however, the majority of field-to-field variation remained unexplained, attributable to producer behavior. Fields with above/below-average irrigation remained consistent across all years, suggesting behavioral components of irrigation variability. Findings illustrate the difficulty of predicting field-scale irrigation due to multiple biophysical and behavioral factors driving irrigation decisions. Increased availability of high-quality, on-farm irrigation data is needed to inform decision-making related to water resources and irrigated agriculture. Benchmarking found that 82% of fields reached ≥70% of yield potential. Nearly 75% of maize and ca. 40% of soybean fields were irrigated above simulated irrigation requirements, indicating room for improvement in irrigation use. Irrigation surplus increased with decreasing soil water holding capacity. Fields irrigated using high-level technology (e.g. soil water sensors) received 95 mm less irrigation than fields where irrigation decisions were not properly informed, with no yield difference between scheduling methods. Half of current irrigation volumes could be potentially reduced in above- or near-average rainfall years if current irrigation surplus is eliminated, but only 10% in drought years. The framework developed can be used to benchmark irrigation use for crop production at different spatial levels (field, region, state), help prioritize extension and research activities, and inform policy and incentive programs..

Book Synopsis National Water Security by : Mustapha Besbes
Download or read book National Water Security written by Mustapha Besbes and published by Springer. This book was released on 2018-05-31 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows how the change of water paradigm has become urgent, and provides evidence for new policies that expand water balance to green and virtual water. The issue of water security concerns drinking water supply but also food safety, linked to agricultural policy. Both rain-fed and irrigated agriculture play complementary roles in food security, and the water issue implies a holistic view of water resources. This view constitutes the book's backstory. The reader will find original ideas that can be applied everywhere because the example of Tunisia is typically a basis to illustrate a universally prevalent situation. The book deals with other important issues: desalination, wastewater recycling, water quality, groundwater overdraft, water savings, governance, knowledge valuing, education, information: upgrading the whole water systems for the future implies emancipation of the whole society.

Book Synopsis Riparian Areas by : National Research Council
Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Synopsis Water use in livestock production systems and supply chains. Guidelines for assessment by : Food and Agriculture Organization of the United Nations
Download or read book Water use in livestock production systems and supply chains. Guidelines for assessment written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-08-14 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Technical Advisory Group (TAG) for Water Use Assessment, composed by 30 international experts, has developed guidelines on water footprinting for livestock supply chains. The mandate of the Water TAG was to provide recommendations to monitor the environmental performance of feed and livestock supply chains over time so that progress towards improvement targets can be measured; apply the guidelines for feed and water demand of small ruminants, poultry, large ruminants and pig supply chains; build on and go beyond the existing FAO LEAP guidelines; and pursue alignment with relevant International Organization for Standardization (ISO) standards, specifically ISO 14040, ISO 14044 (ISO, 2006b and 2006a) and ISO 14046 (ISO, 2014). The guidelines on water use assessment include the impact assessment: the assessment of the environmental performance related to water use of a livestock-related system by assessing potential environmental impacts of blue water consumption following the water scarcity footprint according to the framework provided by ISO 14046 (ISO, 2014); and the assessment of the system’s productivity of green and blue water. The guidelines are thus intended to support the optimization of use of water resources and the identification of opportunities to decrease the potential impacts of water use in livestock production. The Water TAG guidance is relevant for livestock production systems, including feed production from croplands and grasslands, and production and processing of livestock products (cradle-to-gate). It addresses all livestock production systems and livestock species considered in existing LEAP animal guidelines: poultry, pig, small ruminant and large ruminant supply chains.
Book Synopsis The Water Footprint of Modern Consumer Society by : Arjen Y. Hoekstra
Download or read book The Water Footprint of Modern Consumer Society written by Arjen Y. Hoekstra and published by Routledge. This book was released on 2013-06-19 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is not only used in the domestic context, but also in agriculture and industry in the production of commercial goods, from food to paper. The water footprint is an indicator of freshwater use that looks at both direct and indirect use of water by a consumer or producer. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business. This book shows how the water footprint concept can be used to quantify and map the water use behind consumption and how it can guide reduction of water use to a sustainable level. With a number of case studies, it illustrates water use along supply chains and that water consumption at one place is often linked to water use at another. For example, it is calculated that it takes 15,000 litres of water to produce 1 kg of beef, or 8,000 litres of water to produce a pair of jeans. The book shows that imports of water-intensive products can highly benefit water-scarce countries, but also that this creates a dependency on foreign water resources. The book demonstrates how water-scarce regions sometimes, nevertheless, use lots of water for making export products. It raises the issue of sustainable consumption: how can consumers, businesses and governments get involved in reducing the water footprints of final consumer goods?
Book Synopsis Mitigation of Greenhouse Gas Emissions in Livestock Production by : Pierre J. Gerber

This book was released on 2013 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded
Book Synopsis A Sustainability Challenge by : National Research Council
Download or read book A Sustainability Challenge written by National Research Council and published by National Academies Press. This book was released on 2012-03-28 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Research Council's Science and Technology for Sustainability Program hosted two workshops in 2011 addressing the sustainability challenges associated with food security for all. The first workshop, Measuring Food Insecurity and Assessing the Sustainability of Global Food Systems, explored the availability and quality of commonly used indicators for food security and malnutrition; poverty; and natural resources and agricultural productivity. It was organized around the three broad dimensions of sustainable food security: (1) availability, (2) access, and (3) utilization. The workshop reviewed the existing data to encourage action and identify knowledge gaps. The second workshop, Exploring Sustainable Solutions for Increasing Global Food Supplies, focused specifically on assuring the availability of adequate food supplies. How can food production be increased to meet the needs of a population expected to reach over 9 billion by 2050? Workshop objectives included identifying the major challenges and opportunities associated with achieving sustainable food security and identifying needed policy, science, and governance interventions. Workshop participants discussed long term natural resource constraints, specifically water, land and forests, soils, biodiversity and fisheries. They also examined the role of knowledge, technology, modern production practices, and infrastructure in supporting expanded agricultural production and the significant risks to future productivity posed by climate change. This is a report of two workshops.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.
