Quantifying Greenhouse Gas Emissions And Ammonia Volatilization From Soil Amended With Excreta From Ruminants Fed Alternative Forage-Based Diets, Samuel Park

Graduate Theses and Dissertations

Forage-based ruminant diets supplemented with condensed tannins or polyphenolic-containing legumes may alter nitrogen (N) metabolism in the animal and reduce gas emissions from soil receiving excreta. The objective of the study was to determine if soil receiving urine or manure from sheep fed forage diets supplemented with condensed tannin or polyphenolic-containing legumes would decrease N gas emissions. Two field trials were conducted: in the first trial, sheep were fed alfalfa (Medicago sativa L.) silage diets supplemented with 0, 9, 18, or 27% sericea lespedeza (Lespedeza cuneate [Dumont de Courset] G. Don) (n = 4). In the second trial sheep were …

Cultivating The Next Generation Of Pasture Scientists In Australia, Sarita Jane Bennett

IGC Proceedings (1977-2023)

Current students coming through agricultural faculties in Australian universities have grown up in an era of low wool and meat prices, the introduction and acceptance of no-till farming as the norm and a general decrease in mixed farming landscapes in favour of continuous cropping. Since the collapse of the wool reserve price scheme in 1991, wool prices declined and income on wool producing farms followed suit. R & D during this period has also declined from 5-4% agricultural GDP in 1986 to only 3% in 2005 and has favoured research related to cropping rather than that related to pastures and …

Farmers Teaching Farmers: What Motivates Volunteer Farm Trainers?, Evelyne Kiptot, Steven Franzel

IGC Proceedings (1977-2023)

This paper assesses the motivation behind the decisions of smallholder farmers to volunteer as farmer trainers despite the fact that they are not paid for their services. Volunteer farmer trainers (VFTs) are trained in livestock feeds and feeding methods by extension officers. They in turn train other farmers within their community without pay but receive training and seeds for setting up demonstration plots. Data collection was through a combination of focus group discussions and individual interviews with 99 VFTs from seven East Africa Dairy Development (EADD) sites in central and Rift Valley regions of Kenya. Findings of the study showed …

Grass-Based Health, Peter Ballerstedt

IGC Proceedings (1977-2023)

A true discussion of sustainability must focus on improving the condition of humanity. Too often, however, such a discussion is a "dialogue of values that defies consensual definition" (Ratner 2004), with participants implicitly accepting as true numerous foundational beliefs that are factually incorrect or unproven. Dietary policies recommending carbohydrate-based diets are one example. Falsehoods persist despite decades of contradictory re-search results and clinical findings, contaminating a variety of diverse disciplines and discussions. A rational, objective discussion of sustainability in grassland agriculture must confront the issue of public health policy, consider our physical health, the fiscal health of our communities, and …

Impact Of Guinea Grass, Congo Signal And Stylosanthes Hamata On Soil Physico-Chemical Properties And Beneficial Micro Fauna In Mango And Sapota Plantations, B. G. Shivakumar, Narendra S. Kulkarni

IGC Proceedings (1977-2023)

Farming systems are considered to be most important upcoming enterprises to reduce soil erosion and land degradation besides provide timber, fruits, nutritious fodder for live stock population in the poor soil areas (Roy et.al., 2000). Horticulture based farming systems have been recommended as alternate land use systems for sustainable agriculture in semi arid ecosystem for efficient soil plant management and soil fertility management. Studies on micro flora and micro fauna under farming system are required to increase the farming system productivity. Higher species diversity of soil arthropods was observed in grassland system closely followed by the silvipasture …

Gen Z Perspectives On Climate Change And The Future: Having The Courage To Imagine And Fight For A Better World, Isabelle Graj

Independent Study Project (ISP) Collection

I conducted 6 interviews with Gen Z students to investigate how they think climate change will impact their future and how they frame the issue in general. I communicate my findings and analysis with visual context through a zine, which is a form of alternative media created in the 1930s. Today, zines provide a creative approach to exchange ideas and explain contemporary culture (Gisonny and Freedman, 2006, 26). My zine is not meant to be utterly educational but rather it is meant to convey the emotion, confusion, and chaos associated with my findings. The interviews collectively created an image of …

Articles

Intangible Cultural Heritage is at a continuous risk of extinction. Where historical artefacts engine the machinery of intercontinental mass-tourism, socio-technical changes are reshaping the anthropomorphic landscapes everywhere on the globe, at an unprecedented rate. There is an increasing urge to tap into the hidden semantics and the anecdotes surrounding people, memories and places. The vast cultural knowledge made of testimony, oral history and traditions constitutes a rich cultural ontology tying together human beings, times, and situations. Altogether, these complex, multidimensional features make the task of data-mapping of intangible cultural heritage a problem of sustainability and preservation. This paper addresses a …

Should Native Pastures Be Fertilised?, Jo I. Powells, Doug J. Alcock, Luke C. Pope, Denys Garden

IGC Proceedings (1977-2023)

Considerable research has been conducted in recent years demonstrating the ongoing benefits of phosphorus (P) fertiliser in achieving and maintaining higher levels of production from native pastures (Graham 2006; Garden et al. 2003; Lodge et al. 2003; Michalk et al. 2003). However Garden et al. (2003), Hill et al. (2004) and Dorrough et al. (2008) all question the sustainability of this practice by highlighting changes in species composition of these pastures with regard to increasing the introduced annual grass and broadleaf weed components at the expense of the native grasses and forbs but in …

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

IGC Proceedings (1977-2023)

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 …

The North Wyke Farm Platform: Methodologies Used In The Remote Sensing Of The Quantity And Quality Of Drainage Water, Bruce A. Griffith, Jane M. B. Hawkins, Robert J. Orr, Martin S. A. Blackwell, Phil J. Murray

IGC Proceedings (1977-2023)

The North Wyke Farm Platform(NWFP) for agri-environmental research in temperate grassland was established in the UK in 2010 (Orr et al. 2011). Here we describe the instrumentation and methodologies used to monitor the quantity and quality of drainage water at a total of 15 H-flumes draining 5 sub-catchments within three farmlets. Each of 15 flume laboratories is supplied with 3 kW of mains power and connected to both fibre optic and UHF (Ultra High Frequency) radio networks for data exchange. The radio data network also provides telemetry for rain gauges and soil temperature/moisture probes located away from the flumes …

Optimizing The Environmental And Economic Sustainability Of Remote Community Infrastructure, Jamie E. Filer, Justin D. Delorit, Andrew J. Hoisington, Steven J. Schuldt

Faculty Publications

Remote communities such as rural villages, post-disaster housing camps, and military forward operating bases are often located in remote and hostile areas with limited or no access to established infrastructure grids. Operating these communities with conventional assets requires constant resupply, which yields a significant logistical burden, creates negative environmental impacts, and increases costs. For example, a 2000-member isolated village in northern Canada relying on diesel generators required 8.6 million USD of fuel per year and emitted 8500 tons of carbon dioxide. Remote community planners can mitigate these negative impacts by selecting sustainable technologies that minimize resource consumption and emissions. However, …

Optimizing The Environmental And Economic Sustainability Of Contingency Base Infrastructure, Jamie E. Filer

Theses and Dissertations

Contingency bases are often located in remote areas with limited access to established infrastructure grids. This isolation leads to standalone systems comprised of inefficient, resource-dependent infrastructure, which yields a significant logistical burden, creates negative environmental impacts, and increases costs. Planners can mitigate these negative impacts by selecting sustainable technologies. However, such alternatives often come at a higher procurement cost and mobilization requirement. Accordingly, this study aims to develop and implement a novel infrastructure sustainability assessment model capable of optimizing the tradeoffs between environmental and economic performance of infrastructure alternatives.

Botanical Composition And Nutritive Value Of Grazing Lands From Organic And Conventional Agrosilvopastoral Production Systems Of Tropical Southeastern Mexico, Claudia Delgadillo Puga, José Bernardo Sánchez Muñoz, José Nahed-Toral, Miguel Ángel Orantes Zebadua, José Luis Cruz Lopez, Mario Cuchillo Hilario

IGC Proceedings (1977-2023)

In the current situation of agriculture, organic livestock farming has been not only adapted to ameliorate undesirable impacts on environment but also it is challenged to hold or improve agricultural yields obtain-ed by conventional agriculture. In the Mesoamerican biological corridor, a region recognized with an abundant diversity, almost all animal husbandry is based on extensive grazing and traditional agrosilvopastoral systems (Nahed-Toral et al. 2009; Nahed et al. 2010). Furthermore, the conversion of natural jungle areas to new farmland through deforestation is a prevalent problem for biological conservation. Therefore, precise knowledge for suitable agriculture and livestock product-ion are needed …

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

IGC Proceedings (1977-2023)

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 …

Integrated Crop Livestock Systems--A Key To Sustainable Intensification In Africa, A. J. Duncan, S. A. Tarawali, P. Thorne, D. Valbuena, Katrien Descheemaeker, Sabine Homann-Keetui

IGC Proceedings (1977-2023)

Mixed crop-livestock systems provide livelihoods for a billion people and produce half the world’s cereal and around a third of its beef and milk. Market orientation and strong and growing demand for food provide powerful incentives for sustainable intensification of both crop and livestock enterprises in smallholders’ mixed systems in Africa. Better exploitation of the mutually reinforcing nature of crop and livestock systems can contribute to a positive, inclusive growth trajectory that is both ecologically and economically sustainable. In mixed systems, livestock intensification is often neglected relative to crops, yet livestock can make a positive contribution to raising productivity of …

According to the 2018 Intergovernmental Panel on Climate Change, without urgent global changes, climate catastrophe caused by warming of greater than 1.5°C will occur by 2030, endangering the planet's capacity to sustain human populations and livelihoods. The National Network for Sustainable Living Education administered a national survey in January 2017 to assess how well-positioned Extension is to address sustainability in the communities the organization serves. Educators from 40 states responded, and 1,395 usable surveys were received. Survey results will help Extension employees discover opportunities for innovation and relevancy in their programming.

Lean-Green Manufacturing Practices And Their Link With Sustainability: A Critical Review, Wadhah Abualfaraa, Konstantinos Salonitis, Ahmed Al-Ashaab, Maher Ala'raj

All Works

© 2020 by the authors. The current rapidly changing and highly competitive market has put companies under a great pressure towards adopting sustainable practices, in terms of keeping a healthy balance among economic, environmental and social performances. In this context, the lean-green manufacturing approach, which combines lean practices focused on customers' demand, and green practices focused on reducing the business' environmental impact, has gained popularity. Nevertheless, the lean-green manufacturing is still a relatively new practice, lacking a clear and structured research definition, and of significant evidence of successful cases in the practice. In this paper, a literature review is conducted …

The Interplay Between Economic Growth And The Environment: The Case Of China, Christian D. Carpio-Thomas

Electronic Theses and Dissertations

Historically, economic development has come at the cost of environmental degradation. Since the 1980s, neoliberalism rooted in neoclassical theory has dominated mainstream economic thought. The result has been a dramatic increase in environmental degradation in favor of economic growth. The neoliberal recommendations toward development are encapsulated in the Washington and post-Washington Consensuses which promote the liberalization of trade and foreign investment as well as a reliance on market mechanisms. Ultimately, the goal of neoliberalism is to generate growth regardless of the impact that it places on the environment. The case of China presents an example of an economy which pursued …

Biophysical And Socioeconomic Impacts Of Farmer Managed Natural Regeneration In Burkina Faso, Basnewende Brice Fulgence Zoungrana

Electronic Theses and Dissertations

Human actions such as overgrazing, the development of cities at the expense of forests, high intensity and poor agricultural management, and so forth, reduce the resources available for future generations. Because Earth has limited resources, it is important to judiciously use and manage natural resources. Human actions towards nature are the focus of my research in Africa. Increased demands for grazing, agriculture, and ecosystem services led some farmers in developing countries to use unsustainable practices, which may lead to low incomes and poor food nutrition for households. Farmer managed natural regeneration (FMNR) may be a solution to these issues. FMNR …
