Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia
Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia
Journal of Nonprofit Innovation
Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

The accuracy of machine learning tasks critically depends on high quality ground truth data. Therefore, in many cases, producing good ground truth data typically involves trained professionals; however, this can be costly in time, effort, and money. Here we explore the use of crowdsourcing to generate a large number of training data of good quality. We explore an image analysis task involving the segmentation of corn tassels from images taken in a field setting. We investigate the accuracy, speed and other quality metrics when this task is performed by students for academic credit, Amazon MTurk workers, and Master Amazon MTurk …
Biomethane Production From Distillery Wastewater, Zachary Christman
Biomethane Production From Distillery Wastewater, Zachary Christman
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Distillery wastewater treatment is a great ecological problem, for example, India produces 2.7 billion liters of alcohol that results in 40 billion liters of wastewater. However, this material can be seen as a resource since 11 million cubic meters of biogas at 60% methane could be produced in addition to cleaning the water. The distillery has two options of what to do with the biogas. The first is to use the biogas to fuel the distillery making the production plant more energy efficient and removing some of the need to buy natural gas. The other is to upgrade the biogas …

The Report, Biomass as Feedstock for a Bioenergy and Bioproducts Industry: The Technical Feasibility of a Billion-Ton Annual Supply (generally referred to as the Billion-Ton Study or 2005 BTS), was an estimate of “potential” biomass within the contiguous United States based on numerous assumptions about current and future inventory and production capacity, availability, and technology. In the 2005 BTS, a strategic analysis was undertaken to determine if U.S. agriculture and forest resources have the capability to potentially produce at least one billion dry tons of biomass annually, in a sustainable manner—enough to displace approximately 30% of the country’s present petroleum …
Toward Direct Biosynthesis Of Drop-In Ready Biofuels In Plants: Rapid Screening And Functional Genomic Characterization Of Plant-Derived Advanced Biofuels And Implications For Coproduction In Lignocellulosic Feedstocks, Blake Lee Joyce
Doctoral Dissertations
Advanced biofuels that are “drop-in” ready, completely fungible with petroleum fuels, and require minimal infrastructure to process a finished fuel could provide transportation fuels in rural or developing areas. Five oils extracted from Pittosporum resiniferum, Copaifera reticulata, and surrogate oils for Cymbopogon flexuosus, C. martinii, and Dictamnus albus in B20 blends were sent for ASTM International biodiesel testing and run in homogenous charge combustion ignition engines to determine combustion properties and emissions. All oils tested lowered cloud point. Oils derived from Copaifera reticulata also lowered indicated specific fuel consumption and had emissions similar to the ultra-low sulfur diesel control. Characterization …

Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko
Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko
Pr. Mamoudou H. DICKO, PhD
The latest estimates of the FAO demonstrate the problems of the fight against hunger. These problems are manifested by the ever-increasing number of chronically undernourished people worldwide. Their numbers during the 1999-2001 period were estimated at about 840 million of which 798 million live in developing countries. Sub-Saharan Africa alone represented 198 million of those. In this part of Africa the prevalence of undernourishment ranges from 5-34%, causing growth retardation and insufficient weight gain among one third of the children under five years of age and resulting in a mortality of 5-15% among these children. Malnutrition resulting from undernourishment is …

An experimental system was tested in which mechanically harvested burley tobacco plants placed onto steel slotted receivers were retrieved from a field, transported to a field curing structure, and placed onto the structure for air curing by a single worker. The system consisted of a tractor–towed, trailer mechanism that engaged and hoisted loads of approximately 360 burley plants of approximately 1 Mg mass. Ten slotted steel rails, 3.05 m long, holding 36 notched plants were placed onto parallel wooden beams suspended at a height of 2.13 m by wooden posts set in the ground. Burley tobacco was cured in this …

Stubble : Friend And Foe, Department Of Agriculture And Food, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Several articles in this issue of the Journal of Agriculture discuss some of the important issues of stubble management. The articles are condensed from some of the papers presented at a stubble workshop at Geraldton in 1991.
Stubble Handling Machinery, Greg Haydon
Stubble Handling Machinery, Greg Haydon
Journal of the Department of Agriculture, Western Australia, Series 4
Farming in Western Australia, and in Australia, has undergone a revolution over the past 15 to 20 years. Two significant changes have been the cessation of ploughing to kill weeds, that is, the change from discs to tines, and the reduction in tillage through the use of agricultural chemicals. These have been important changes that have had conservation benefits. However, to handle stubble to best effect, further changes in machinery, newer machinery and combinations of machines will be needed. In this article, the author discusses current and possible future practces.
Narrow-Winged Seeder Points Reduce Water Erosion And Maintain Crop Yields, Kevin Bligh
Narrow-Winged Seeder Points Reduce Water Erosion And Maintain Crop Yields, Kevin Bligh
Journal of the Department of Agriculture, Western Australia, Series 4
Sowing crops without loosening the topsoil by tillage reduces water erosion. It can increase infiltration of rainfall into loamy soils, thereby reducing runoff and increasing potential crop yields. Crop yields were maintained after I1 seasons of seeding an Avon Valley loam near Beverley with minimum and no-tillage seeding operations. Infiltration increased significantly from 80 per cent of the 1983 growing-season rainfall under the traditional three tillage operations, to 87per cent under a single tillage operation using a combine seed drill. Infiltration increased further to 96 per cent under a no-tillage system using a triple^lisc drill. At Gnowangerup, 80 per cent …

Whole-Farm Planning : Success At Wilgi Creek, Kevin Shanhun
Journal of the Department of Agriculture, Western Australia, Series 4
Ian and Bev Lynch own Wilgi Creek, a 376 ha mixed farming property at West Mount Barker in the 700 mm rainfall zone. In 1983, they started a whole-farm plan to overcome the problems of declining production caused by waterlogging (their biggest problem), salinity and deterioration of the remnant native vegetation. Today, their property is an example of a successful, wholefarm land conservation plan based on agroforestry, timber production, water harvesting and improved pastures.
The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard
The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard
Journal of the Department of Agriculture, Western Australia, Series 4
Harvest losses represent a significant reduction in lupin production and farm productivity.
Since 1984, the Department's Farm Machinery Research and Liaison Unit at the Dryland Research Institute has studied the lupin harvesting operation to improve its mechanical efficiency. An experimental and a prototype harvesting front were built and tested in the field. Guidlines for efficient lupin harvesting were produced, and commercial modifications developed.

Improved Fertilizing Practices On The Peel-Harvey Catchment, P T. Arkell
Journal of the Department of Agriculture, Western Australia, Series 4
Broad-acre farmers in the Peel-Harvey catchment have met a challange and achieved a great deal since the fertilizer extension programme started in 1983.
The main objective of the extension programme has been to ensure that every year three-quarters of the farmers make economically and technically sound fertilizer decisions, thus causing a minimum amount of phosphorus to enter the waterways of the Peel-Harvey estuarine system.
Calibration Of Boom Sprays, J R. Peirce
Calibration Of Boom Sprays, J R. Peirce
Journal of the Department of Agriculture, Western Australia, Series 4
Boom sprays have become increasingly common on Western Australian farms, allowing farmers to take advantage of modern herbicided.
Most boom sprays used on farms have 50 cm nozzle spacings and require calibrating regularily to ensure accurate herbicide application.
By following these steps, the boom will deliver accurate amounts of herbicide.

Options For Machinery And Labour, A F. Herbert
Journal of the Department of Agriculture, Western Australia, Series 4
Machinery is one of the highest costs in farming today. It is not unusual for capital investment in machinery to be 20 to 30 percent of the total investment in the farm.
On an annual basis, expenditure directly attributable to machinery can be 40 per cent or more.
This article cannon be a panacea for everyone to reduce machinery costs - each farm is different. But some of the issues might be of help.

Replacing Farm Machinery, R Crossman
Journal of the Department of Agriculture, Western Australia, Series 4
In talking of machinery replacement it seems implied that the replacement items of plant are bigger and therefore better than their predecessers. It is also implied that plant replacement is becoming more costly.
Before any decision to replace machinery, the reason for replacement should be carefully considered.
There may be alternatives to the bigger and better solution.
Getting The Best From Tractor Tyres, J Quealy
Getting The Best From Tractor Tyres, J Quealy
Journal of the Department of Agriculture, Western Australia, Series 4
The amount of pull a tractor develops depends largely on tyre efficiency and so with so many tyre size options for the one tractor model it is very easy to make the wrong decision on tyre fitment.
Tyre efficiency varies with tractor weight, soil conditions, inflation pressure and tyre size.
Hers we look at some of these factors and how changing them may affect efficiency.

Journal of the Department of Agriculture, Western Australia, Series 4
The oil produced from sunflowers falls into the "polyunsaturated" group and usually commands a premium price on world markets.
Some Western Australian farmers seeking to diversify their cropping programmes in the face of marketing difficulties for many agricultural products are trying sunflowers, although commercial production has not yet been achieved.
This article sets out some basic information for farmers wishing to try sunflowers.

Irrigating Dry Season Crops In The Ord Valley : How To Prepare Land For Sowing, D F. Beech
Journal of the Department of Agriculture, Western Australia, Series 4
THE best way to grow dry season crops of safflower, linseed and rapeseed under irrigation in the Ord Valley is by sowing on to broad flat ridges, separated by small furrows 3 ft. 6 in. apart.
This system of sowing is called the "corrugation" method.
The Effects Of Tillage Implements On Cereal Yields, H M. Fisher
The Effects Of Tillage Implements On Cereal Yields, H M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Careful soil preparation is essential for cereal crops grown without fallow on clover ley land.
Crops give better yields where the land is broken up with a mouldboard or disc plough rather than a scarifier or similar machine.
The implements differ appreciably in their capacity to control weed growth and this is largely responsible for variations in cereal yields. "Takeall" disease is reduced by efficient weed control.
Bulk Handling Of Superphosphate, H G. Cariss
Bulk Handling Of Superphosphate, H G. Cariss
Journal of the Department of Agriculture, Western Australia, Series 4
A MAJOR factor in our agricultural production is the outlay for fertilisers, including the cost of their application to the land.
Any means which can be employed to reduce these costs are therefore of extreme importance to the State's agriculture.
The bulk-handling of fertilisers could be one way of reducing these costs to the farmer.
