The Green, Blue And Grey Water Footprint Of Farm Animals And Animal Products. Volume 1: Main Report, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

The projected increase in the production and consumption of animal products is likely to put further pressure on the globe’s freshwater resources. The size and characteristics of the water footprint vary across animal types and production systems. The current study provides a comprehensive account of the global green, blue and grey water footprints of different sorts of farm animals and animal products, distinguishing between different production systems and considering the conditions in all countries of the world separately. The following animal categories were considered: beef cattle, dairy cattle, pig, sheep, goat, broiler chicken, layer chicken and horses. The study shows …

Treenuts And Groundnuts In The Eat-Lancet Reference Diet: Concerns Regarding Sustainable Water Use, Davy Vanhama, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

The EAT-Lancet universal healthy reference diet recommends an increase in the consumption of healthy foods, among which treenuts and groundnuts. Both are, however, water-intensive products, with a large water footprint (WF) per unit of mass and protein and already today contribute to blue water stress in different parts of the world. The envisaged massive required increase in nut production to feed a global population with this reference diet, needs to occur in a water-sustainable way. In this paper, we identify and quantify where current nut production contributes to local blue water stress and discuss options for water-sustainable nut production. We …

Western Australian Soil Groups - A Diagnostic Key To Identify Soils In Western Australia (5th Edition), Paul Galloway, Dennis Van Gool, Angela Stuart-Street, Edward A. Griffin, Shahab Pathan, Noel R. Schoknecht

Resource management technical reports

The aim of the Western Australian soil groups (WA soil groups) is to classify soils of Western Australia into a limited set using criteria that are easy to recognise in the field. It is a general-purpose classification with a focus on agronomic and rangeland grazing potential. The WA soil groups are designed for WA needs. It complements the Australian Soil Classification (ASC) by grouping the continuum of soils into a limited set of soil types, which simplifies soil variability for generalists, allows soil surveyors to create standardised soil-type legends for mapping products and permits further analyses of spatial data for …

Standardized Precipitation Index: User Guide, Mark Svoboda, Michael Hayes, Deborah Wood

National Drought Mitigation Center: Faculty Publications

Over the years, there has been much discussion on what drought indices should be used in a particular climate and for what application. Many drought definitions and indices have been developed and attempts have been made to provide some guidance on this issue. With this in mind, the Interregional Workshop on Indices and Early Warning Systems for Drought was organized and held at the University of Nebraska-Lincoln, United States of America, from 8 to 11 December 2009. It was jointly sponsored by the School of Natural Resources (SNR) of the University of Nebraska, the United States National Drought Mitigation Center …

Guide To Supplementary Feeding And Budgeting, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Supplementary feeding of sheep, with grain, hay or silage is necessary when pastures or stubbles are deficient in energy and protein.

A good supplementary feeding program will ensure sheep utilise as much dry paddock feed as possible as well as provide sufficient supplementary feed for maintenance or growth.

The Department of Primary Industries and Regional Development recommends supplementary or confined paddock feeding to maintain livestock productivity and avoid animal welfare and soil erosion problems.

Gps Accuracy Of Smartphones For Crowdsourcing Research, Derron L. Dike

Master of Science in Environmental Sciences and Management Projects

ABSTRACT GPS Accuracy of Smartphones for Crowdsourcing Research Derron Dike Utilizing crowdsourcing with smartphones as a method for field data collection can contribute an array of data for scientific studies and land management applications. This study used crowdsourcing to examine smartphone built-in GPS performance for providing location-specific information with potential forestry applications. The usability of smartphones for GPS data collection in forestry studies or other practical applications is dependent on the level of accuracy required for those applications. A Smartphone Accuracy Trial was designed to test the GPS accuracy performance of current smartphones. Participants used the ArcGIS Field Maps application …

Spray-Topping Pastures, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Spray-topping or pasture topping is the application of a sub-lethal rate of herbicide when grasses are coming into head and flowering.

The aim is to reduce the production of viable seed and the seedling population in the following year. The grass is not killed by the herbicide application.

Spray-topping is normally carried out in preparation for the following season's cropping program.

Perceived And Recorded Temperature In Aircraft Cabins During 143 Flights, Matthew Nicholls, Peter Vink

Journal of Aviation Technology and Engineering

This essay reports on the perceived and recorded temperature in aircraft cabins during 143 flights. In each flight, passengers reported their experience. They recorded temperature and humidity after boarding and one hour later. The reports show that fewer than half of the passengers perceived the temperature as “good.” Most passengers (39%) perceived it as hot, and some (17%) perceived it as cold. Comparing the temperatures with guidelines shows that 18% of the recorded temperatures in the cabin were empirically too hot and 2% empirically too cold. The differences between passengers in what they perceive as a good temperature are large, …

Sheep Production, Profitability And Greenhouse Gas Emission Of Mixed Farming Systems In Western Australia's Wheatbelt, Tafesse Estifanos, Amir Abadi Abadi Ghadim, Kate Pritchett, Christophe D'Abbadie, Johnny Machon, Paul Mattingley, Bradley Plunkett, Gus Manatsa, Kerrine Blenkinsop, Ross Kingwell, Clinton K.

Animal production and livestock research reports

The south-western agricultural area of Western Australia is a vital contributor to Australia's agricultural output. It generates over $10 billion annually in agricultural production from 2017–18 to 2021–22 and more than $8 billion in export value over the same period. Mixed farming systems characterise the region, producing broadacre crops (primarily wheat, barley, and canola) and livestock. The region's livestock industry is dominated by sheep production for meat and wool, and the state’s share of the national sheep flock in 2020–21 was at 18%.

This report provides a comprehensive review and industry analysis of sheep production in WA, its economic significance, …
