Determinants Of Female Bargaining Power In Northern Mozambican Households, Sara Marilyn Gardner May 2021

Determinants Of Female Bargaining Power In Northern Mozambican Households, Sara Marilyn Gardner

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Melinda Gates stated, “If you search for poverty, you will find women who don’t have power. If you explore prosperity, you will find women who do have power and use it.” Throughout Sub-Saharan Africa, women are expected to perform disproportional amounts of labor but are often ignored in household decision-making regarding social and economic matters. The United Nations Development Program (UNDP) states that women in Mozambique are highly disadvantaged, relative to men, due to low levels of education, maternal health risks, restricted economic prospects, and cultural norms. This study aims to better understand the causes of female empowerment in ...

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr Mar 2021

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

Incorporation Of Summer Annual Mixtures Into Grazing Systems In Kentucky, Kelly Marie Mercier Jan 2021

Incorporation Of Summer Annual Mixtures Into Grazing Systems In Kentucky, Kelly Marie Mercier

Theses and Dissertations--Plant and Soil Sciences

Utilizing summer annual grass-legume forage mixtures has the potential to improve forage yield and nutritive characteristics, and/or animal performance during times when cool-season pasture growth is limited by high temperatures. Legumes can utilize atmospheric nitrogen, which can increase crude protein and forage digestibility in mixtures. As nitrogen application generally improves both the yield and nutritive characteristics of summer annual forages, but can have a negative effect on legume competitiveness, nitrogen fertilizer recommendations for legume-containing summer annual mixtures are not well established.

Two experiments were conducted to determine the feasibility of utilizing summer annual mixtures in Kentucky, USA. The first ...

Control Of Volunteer Corn In Enlist Corn And Economics Of Herbicide Programs For Weed Control In Conventional And Multiple Herbicide-Resistant Soybean Across Nebraska, Adam M. Striegel May 2020

Control Of Volunteer Corn In Enlist Corn And Economics Of Herbicide Programs For Weed Control In Conventional And Multiple Herbicide-Resistant Soybean Across Nebraska, Adam M. Striegel

Theses, Dissertations, and Student Research in Agronomy and Horticulture

With commercialization of multiple herbicide-resistant corn and soybean cultivars, producers have new management options for controlling herbicide-resistant weeds and volunteer corn. Corn-on-corn production systems are common in irrigated fields in southcentral Nebraska which can create issues with volunteer corn management in corn fields. Enlist corn contains a new multiple herbicide-resistant trait providing resistance to 2,4-D choline, glyphosate, and the aryloxyphenoxypropionate (FOPs). Field experiments were conducted in 2018 and 2019 at South Central Agricultural Laboratory near Clay Center, Nebraska with the objective to evaluate ACCase-inhibiting herbicides and herbicide application timing on volunteer corn control, Enlist corn injury, and yield. Glyphosate ...


The Significance Of Nomadic Pastoralism For Sustaining Soil Fertility In Northern Karnataka, India, Athani B., Gopikrishna, N. Kuruba Apr 2020

The Significance Of Nomadic Pastoralism For Sustaining Soil Fertility In Northern Karnataka, India, Athani B., Gopikrishna, N. Kuruba

International Grassland Congress Proceedings

Pastoralist groups in India, including the Raika of Rajasthan, Pullikulum cattle breeders in Tamil Nadu, and groups such as the Dhangar, Kuruba and Kuruma of the Deccan Plateau realize a major proportion of their income from penning their herds and flocks on farmers’ fields. Focusing on shepherds from Northern Karnataka, this paper makes a first attempt at calculating the impact of penning on livelihoods, soil fertility and the national economy.


Economics Of Camel Rearing On Grasslands In Gujarat, Khem Chand, B. L. Jangid, Subhash Kachhawa Apr 2020

Economics Of Camel Rearing On Grasslands In Gujarat, Khem Chand, B. L. Jangid, Subhash Kachhawa

International Grassland Congress Proceedings

Camel in India is primarily reared for carting/draft, agricultural operation, transportation in addition to the secondary utility of milk and hair production (Saini et al 2006). The One humped or Dromedary camel (Camelus dromedarius) is an important livestock species uniquely adapted to hot and arid environments (Schwartz, 1992). It is important livestock specie contributing significantly in rural economy and livelihood of desert dwellers in Kachchh region of Gujarat. It still plays a very distinctive role in various agricultural operations and rural transportation in dry land farming (Rajput and Tripathi, 2005). The Kachchh region of Gujarat has large camel herders ...


Economic Review Of Pasture Development Options For North Australian Beef Enterprises, Neil D. Macleod, Dianne Mayberry, Lindsay Bell, Ian Watson Apr 2020

Economic Review Of Pasture Development Options For North Australian Beef Enterprises, Neil D. Macleod, Dianne Mayberry, Lindsay Bell, Ian Watson

International Grassland Congress Proceedings

Beef cattle grazing (~14 million head) native pastures is the dominant economic use of northern grazing lands (2.3 million km2). Few enterprises make positive economic returns in most years or achieve the necessary productivity gains (~2% per annum) to offset an ongoing cost-price squeeze (McCosker et al., 2010). A significant contributor to poor performance is low reproductive performance, management of first calving heifers, calf growth and weaning rates and liveweight gain - linked to nutrition and the low quality of pastures. Pasture development technologies (Gramshaw and Walker, 1988) are available but uptake has been poor. Three pasture development options offering ...


Tall Fescue: Forage And Seed Production Economics, M. Anowarul Islam Apr 2020

Tall Fescue: Forage And Seed Production Economics, M. Anowarul Islam

International Grassland Congress Proceedings

Irrigated grass pastures are essential components of western U.S. agriculture, especially on cattle ranches of the intermountain region. Unfortunately, the yield and quality of these grasslands are relatively low compared to the national average because of current management practices (Jacobs et al., 1993). Attempts have been made to increase forage yields of these pastures by fertilization and applying or controlling irrigations but these efforts have resulted in minimum success (Jacobs et al., 1993). The price increase of fertilizer, energy, and fuel has made improvement of these natural grasslands more difficult and thus threatens the profitability and sustainability of current ...


Forage Legumes Intercropping And Nitrogen Management Effects On Performance Of Guinea Grass (Panicum Maximum) Varieties In Bundelkhand Region Of India, Mukesh Choudhary, G. Prabhu Mar 2020

Forage Legumes Intercropping And Nitrogen Management Effects On Performance Of Guinea Grass (Panicum Maximum) Varieties In Bundelkhand Region Of India, Mukesh Choudhary, G. Prabhu

International Grassland Congress Proceedings

Guinea grass (Panicum maximum Jacq.) is one of the important forage grass of the tropics with good yield potential, palatability, persistence and quality fodder (Sukhchain, 2010). The low crude protein productivity of guinea grass can be enhanced through its intercropping with forage legumes to sustain ruminant animals throughout the year. The intercropping of legumes with guinea grass will also optimize forage production per unit area, especially during rabi season. Further, its productivity can also be increased through N management as it is heavy feeder due to perennial and multi-cut nature.


Using Forages To Conserve Water In Semi-Arid Irrigated Cropping Systems, Rick Kellison, V. G. Allen, C. P. Brown, D. L. Doerfert, P. N. Johnson, S. J. Maas, C. P. West Mar 2020

Using Forages To Conserve Water In Semi-Arid Irrigated Cropping Systems, Rick Kellison, V. G. Allen, C. P. Brown, D. L. Doerfert, P. N. Johnson, S. J. Maas, C. P. West

International Grassland Congress Proceedings

The Texas High Plains are part of the largest, contiguously irrigated cropland in the USA, and draws water from the Ogallala aquifer. High crop prices, increased demand for maize for ethanol production, and severe drought have increased water depletion rates. Research has shown that integrating forages and grazing cattle into the cotton-dominant cropping system can reduce overall water use (Allen et al. 2012) while still offering farmers positive net returns (Johnson et al. 2013). Integrating forages with row crops also reduces needs for nitrogen (N) fertilizer, rebuilds soil organic matter (Acosta-Martinez et al. 2010), and reduces fossil energy use and ...


The Value Of Modeling Botanical Composition Change In Grasslands, Karl Behrendt Feb 2020

The Value Of Modeling Botanical Composition Change In Grasslands, Karl Behrendt

International Grassland Congress Proceedings

The integration of grassland dynamics, livestock production and economics is necessary to improve decision making regarding grassland resource development and management. Within a sward, the relative competitive ability of different species and the way management interacts with the environment both play a significant role in determining the competition between species, future states of the grassland sward, ecological impact of the grassland and its potential for livestock production (Kemp and King, 2001). The impact of botanical composition shifts on grassland productivity will depend on the nutritive value and yield potential of the invasive species against those of the resident species. The ...


Integrating Beef And Cotton Production Reduces Irrigation Needs In The Texas Southern High Plains, C. Philip Brown, V. G. Allen, Rick Kellison, P. Green, C. J. Zilverberg, P. Johnson, V. Acosta-Martinez, C. P. West Feb 2020

Integrating Beef And Cotton Production Reduces Irrigation Needs In The Texas Southern High Plains, C. Philip Brown, V. G. Allen, Rick Kellison, P. Green, C. J. Zilverberg, P. Johnson, V. Acosta-Martinez, C. P. West

International Grassland Congress Proceedings

The Texas High Plains is a semiarid agricultural region located in the central south plains of the United States. This area exemplifies semiarid regions where water is becoming scarce. Crop production depends heavily on irrigation primarily from the Ogallala aquifer at non-sustainable rates of use. Irrigated monoculture cotton (Gossypium hirsutum L.) is the dominant crop but grazing livestock in this once vast grassland is re-emerging as the aquifer declines. Environmental benefits of integrated crop and livestock systems have been suggested. We compared a cotton monoculture with an integrated cotton-forage-beef stocker steer system over 10 yr to determine effects on irrigation ...


A Strategic Approach To Developing The Role Of Perennial Forages For Crop-Livestock Farmers, Rick Llewellyn, Michael Robertson, Richard C. Hayes, David Ferris, Clinton K. Revell, Katrien Descheemaeker Feb 2020

A Strategic Approach To Developing The Role Of Perennial Forages For Crop-Livestock Farmers, Rick Llewellyn, Michael Robertson, Richard C. Hayes, David Ferris, Clinton K. Revell, Katrien Descheemaeker

International Grassland Congress Proceedings

A substantial proportion of Australian animal production from grazing comes from regions and farms where cropping is the major enterprise. Developing new and improved grazing systems for mixed farms where crop production is the major driver of farm management decisions presents a unique research and development challenge. In this paper we describe a multi-disciplinary farming-systems research approach (‘EverCrop’) aimed at improving farm profitability, risk management and environmental impacts through the development and integration of new grazing options. It has been used to analyse and target new opportunities for farmers to benefit from perennial species across dry Mediterranean-type and temperate regions ...


Epochs Of Ecology: The Transition From Feudalism To Capitalism, Jacob Alexander Tucker Jan 2020

Epochs Of Ecology: The Transition From Feudalism To Capitalism, Jacob Alexander Tucker

Electronic Theses and Dissertations

The transition from feudalism to capitalism has undoubtedly been one of the most fruitful and complicated debates amongst economic historians in the 20th and 21st centuries. With the advent of global ecological collapse, there is a necessity to examine and theorize the movement from feudalism to capitalism through the lens of ecology. While in mainstream economics the environment is either entirely dismissed or nature’s role in economics remains subsidiary to the human economy, in the field of Marxian economics, human’s interacting through nature is at the core of the entire theory. For that reason, this thesis takes earnestly ...


Making Grain Sorghum Great Again: A Two-Year Case Study In Southern Illinois, Christian Heredia Jan 2020

Making Grain Sorghum Great Again: A Two-Year Case Study In Southern Illinois, Christian Heredia

Creative Components

Grain sorghum, Sorghum bicolor (L.) Moench, in Illinois, known hereafter as sorghum, was an important rotational crop that could handle the unique stresses of the southern third of the state. The success of sorghum was attributed, in part, to the marginal crop production land of the region, the appropriate growing season, and the proximity to river terminals for easy grain marketing. However, the development of herbicide tolerant crop cultivars, advances in crop breeding, and consolidation of farms and grain terminals have reduced sorghum acres to pre-1970s level. This case study identified the economic opportunity, addresses agronomic practices, and suggests farmers ...

CSE Journal Articles

Abstract

Is true that it is not only the consumers that make the economy prospers? Business and government also play a role in the economy of a country and corporation. “The GLOBAL technology economy is driven perhaps by the example of a consumer-based society and capital driven citizenry," according to the article in the investor guide of 2013. The role of the government is very important in businesses, organizations and consumers alike depending on the decisions made by the government officials spending of the government. Research have indicated that dependencies of government, organizations, businesses and consumers are intertwine or intermediary ...


Global Impacts From Improved Tropical Forages: A Meta-Analysis Revealing Overlooked Benefits And Costs, Evolving Values And New Priorities, Douglas S. White, Michael Peters, Peter Horne Dec 2019

Global Impacts From Improved Tropical Forages: A Meta-Analysis Revealing Overlooked Benefits And Costs, Evolving Values And New Priorities, Douglas S. White, Michael Peters, Peter Horne

International Grassland Congress Proceedings

The wider use and improved performance of planted tropical forages can substantially change social, economic and environmental landscapes. By reviewing impact-related studies published in the past two decades, this paper shows how evolving development priorities have influenced the types of impacts being documented. A meta-analysis was used to examine 98 studies according to: (1) breadth of reported effects, as related to development goals of social equity, economic growth and environmental sustainability; (2) extent of effects, ranging from intermediate to longer-term impacts; and (3) measurement precision (identification, description and quantification). Impacts have been assessed for fewer than half of the documented ...

Scenario Analysis: Risk And Return Of Aluminium Tolerant Lucerne, Claire D. Lewis, J. L. Jacobs, K. F. Smith, G. Spangenberg, B. Malcolm

International Grassland Congress Proceedings

Lucerne (Medicago sativa) yield is limited by aluminium stress associated with acid soils (Campbell et al. 1988; Scott et al. 2008). With the aid of transgenic technologies, the development of aluminium tolerant (Al Tol) lucerne is proposed. Modelled scenario analysis was conducted to explore the potential net benefits of Al Tol lucerne as part of a grazing system for a sheep production system in the high rainfall zone of south west Victoria.


Diversity, Trends, Opportunities And Challenges In Australian Grasslands–Meeting The Sustainability And Productivity Imperatives Of The Future?, Lindsay W. Bell, Richard C. Hayes, Keith G. Pembleton, Cathy M. Waters Nov 2019

Diversity, Trends, Opportunities And Challenges In Australian Grasslands–Meeting The Sustainability And Productivity Imperatives Of The Future?, Lindsay W. Bell, Richard C. Hayes, Keith G. Pembleton, Cathy M. Waters

International Grassland Congress Proceedings

Grassland production systems contribute 40% to Australia’s gross agricultural production value and utilise over 50% of its land area. Across this area a broad diversity of systems exist, but these can be broadly classified into four main production systems: 1. Pastoral grazing of mainly cattle at low intensity (i.e. < 0.4 DSE/ha) on relatively unimproved native rangelands in the arid and semi-arid regions of northern and central Australia; 2. Crop-livestock systems in the semi-arid zone where livestock graze a mixture of pastures and crops which are often integrated; 3. High rainfall permanent pasture zone in the coastal hinterland and highlands and; 4. Dairy systems covering a broad range of environments and production intensities. A notable trend across these systems has been the replacement of wool sheep with beef cattle or meat sheep breeds, which has been driven by low wool prices. Although there is evidence that most of these systems have lifted production efficiencies over the past 30 years, total factor productivity growth has failed to match the decline in terms of trade. This has renewed attention on how research and development can help increase productivity. In addition, these industries are facing increasing scrutiny to improve their environmental performance and develop sustainable production practices. We propose several areas in which grasslands research and development might help provide gains in system productivity and sustainability. In particular, pasture productivity might be improved by filling gaps in the array of pastures available either through exploring new species or improving the adaptation and agronomic characteristics of species currently sown. Meanwhile there is a need to maintain efforts to overcome persistent and emerging constraints to pasture productivity. Improving livestock forage feed systems and more precise and lower cost management of grasslands would translate into improved utilisation and conversion of forage produced into livestock products. There is significant scope to capture value from the ecological services grasslands provide and mitigate greenhouse gas emissions from livestock production. Multi-purpose grasslands provide not only grazing for livestock but produce other food products such as grain which may also have potential to integrate livestock with cropping. However, reduced human research capacity in pasture science will challenge our ability to realise these potential opportunities unless efforts are made to attract and support a new generation of pasture scientists.

Assessment Of Watersheds For Sustainable Agriculture In Karnataka, India, Nicholas Adam Charles Jun 2019

Assessment Of Watersheds For Sustainable Agriculture In Karnataka, India, Nicholas Adam Charles

FIU Electronic Theses and Dissertations

Modernization of traditional small-scale irrigation tanks in India is becoming increasingly popular. This is due to high costs of the alternative, of developing and constructing large-scale projects in rural areas. Examination of management strategies, resource allocation, and collective action has become paramount for promoting food security and livelihoods in water-stressed areas of Southeast Asia. Geographic Information System (GIS) and Remote Sensing techniques are valuable to assessing the management of these irrigation systems, specifically small water storage reservoirs that capture runoff from the monsoon known as irrigation tanks. The primary goal of this study is to develop a stakeholder-informed approach to ...


Ecological And Economic Implications Of Increased Storm Frequency And Severity For Boreal Lakes, Kathryn Warner May 2019

Ecological And Economic Implications Of Increased Storm Frequency And Severity For Boreal Lakes, Kathryn Warner

Electronic Theses and Dissertations

In boreal regions, increased precipitation events have been linked to increased concentrations of dissolved organic carbon (DOC), however less is known about the extent and implications of these events on lakes. We assessed the effects of precipitation events on six drinking water lakes in Maine, USA to better understand how DOC concentration and quality change in response to precipitation events. Our results revealed three types of responses: (1) an initial spike in DOC concentrations and quality metrics; (2) a sustained increase in DOC concentrations and quality metrics and; (3) no change during all sampling periods. Lake residence time was a ...


Endowment Effects In Chimpanzees, Owen D. Jones, Sarah F. Brosnan, Susan P. Lambeth, Mary Catherine Mareno, Amanda S. Richardson, Steven Schapiro Apr 2019

Endowment Effects In Chimpanzees, Owen D. Jones, Sarah F. Brosnan, Susan P. Lambeth, Mary Catherine Mareno, Amanda S. Richardson, Steven Schapiro

Owen Jones

Human behavior is not always consistent with standard rational choice predictions. The much-investigated variety of apparent deviations from rational choice predictions provides a promising arena for the merger of economics and biology. Although little is known about the extent to which other species also exhibit these seemingly irrational patterns of human decision-making and choice behavior, similarities across species would suggest a common evolutionary root to the phenomena.

The present study investigated whether chimpanzees exhibit an endowment effect, a seemingly paradoxical behavior in which humans tend to value a good they have just come to possess more than they would have ...


Law, Biology, And Property: A New Theory Of The Endowment Effect, Owen D. Jones, Sarah F. Brosnan Apr 2019

Law, Biology, And Property: A New Theory Of The Endowment Effect, Owen D. Jones, Sarah F. Brosnan

Owen Jones

Recent work at the intersection of law and behavioral biology has suggested numerous contexts in which legal thinking could benefit by integrating knowledge from behavioral biology. In one of those contexts, behavioral biology may help to provide theoretical foundation for, and potentially increased predictive power concerning, various psychological traits relevant to law. This Article describes an experiment that explores that context.

The paradoxical psychological bias known as the endowment effect puzzles economists, skews market behavior, impedes efficient exchange of goods and rights, and thereby poses important problems for law. Although the effect is known to vary widely, there are at ...


An Economic Feasibility Assessment Of Autonomous Field Machinery In Grain Crop Production, Jordan Murphy Shockley, Carl R. Dillon, Scott A. Shearer Feb 2019

An Economic Feasibility Assessment Of Autonomous Field Machinery In Grain Crop Production, Jordan Murphy Shockley, Carl R. Dillon, Scott A. Shearer

Agricultural Economics Faculty Publications

A multi-faceted whole farm planning model is developed to compare conventional and autonomous machinery for grain crop production under various benefit, farm size, suitable field day risk aversion, and grain price scenarios. Results suggest that autonomous machinery can be an economically viable alternative to conventional manned machinery if the establishment of intelligent controls is cost effective. An increase in net returns of 24% over operating with conventional machinery is found when including both input savings and a yield increase due to reduced compaction. This study also identifies the break-even investment price for intelligent controls for the safe and reliable commercialization ...
