Urban Farming: Empowerment To Increase Economic, Education, And Nutritional Benefit For The Sub-Urban Community, Nasruddin Nasruddin, Yusuf Donner Dwiyantama, Banu Muhammad, Anom Bowalaksono, Dian Ayubi, Sarah Islamiati Pertiwi

ASEAN Journal of Community Engagement

This article discusses the urban farming program at Sekolah Master in Beji, Depok, Indonesia, which aims to provide the community with broader benefits, such as economy, education, and increased nutritional value. The project involves planting method that was introduced to this school community. The program itself consists of several stages, starting from the preparation—dissemination of the program and designing a plan for the greenhouse, the implementation—constructing the greenhouse and installing the automatic water system, planting the vegetation, and monitoring and evaluation of the program. Eventually, an evaluation of the successful program is required to determine whether the program can be …


A Qualitative Look Into Repair Practices, Jumana Labib Aug 2022

A Qualitative Look Into Repair Practices, Jumana Labib

Undergraduate Student Research Internships Conference

This research poster is based on a working research paper which moves beyond the traditional scope of repair and examines the Right to Repair movement from a smaller, more personal lens by detailing the 6 categorical impediments as dubbed by Dr. Alissa Centivany (design, law, economic/business strategy, material asymmetry, informational asymmetry, and social impediments) have continuously inhibited repair and affected repair practices, which has consequently had larger implications (environmental, economic, social, etc.) on ourselves, our objects, and our world. The poster builds upon my research from last year (see "The Right to Repair: (Re)building a better future"), this time pulling …


Design Of A Shallow-Aero Ebb And Flow Hydroponics System And Associated Educational Module For Tri Cycle Farms, Julie Halveland May 2020

Design Of A Shallow-Aero Ebb And Flow Hydroponics System And Associated Educational Module For Tri Cycle Farms, Julie Halveland

Biological and Agricultural Engineering Undergraduate Honors Theses

Tri Cycle Farms, whose main mission is to reduce food insecurity in their community, is a non- profit urban farm in Fayetteville, Arkansas. The “Tri” in their name refers to the three parts of their foundation: giving a third of their yield to volunteers, giving a third to local food pantries, and selling a third to sustain the farm and demonstrate the economy of local food production. They want to expand on the third part and have a vision of building a hydroponic greenhouse with the intention that it will create more crops to sell and give, as well as …

Exploring Agricultural Production Systems And Their Fundamental Components With System Dynamics Modelling, Jeffrey P. Walters, David W. Archer, Gretchen F. Sassenrath, John R. Hendrickson, Jon D. Hanson, John M. Halloran, Peter Vadas, Vladimir J. Alarcon

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Agricultural production in the United States is undergoing marked changes due to rapid shifts in consumer demands, input costs, and concerns for food safety and environmental impact. Agricultural production systems are comprised of multidimensional components and drivers that interact in complex ways to influence production sustainability. In a mixed-methods approach, we combine qualitative and quantitative data to develop and simulate a system dynamics model that explores the systemic interaction of these drivers on the economic, environmental and social sustainability of agricultural production. We then use this model to evaluate the role of each driver in determining the differences in sustainability …

A Five-Year Assessment Of Corn Stover Harvest In Central Iowa, Usa, Douglas Karlen, Stuart J. Birrell, J. Richard Hess

Douglas L Karlen

Sustainable feedstock harvest strategies are needed to ensure bioenergy production does not irreversibly degrade soil resources. The objective for this study was to document corn (Zea mays L.) grain and stover fraction yields, plant nutrient removal and replacement costs, feedstock quality, soil-test changes, and soil quality indicator response to four stover harvest strategies for continuous corn and a corn–soybean [Glycine max. (L.) Merr.] rotation. The treatments included collecting (1) all standing plant material above a stubble height of 10 cm (whole plant), (2) the upper-half by height (ear shank upward), (3) the lower-half by height (from the …


Overcoming India’S Food Security Challenges: The Role Of Intellectual Property Management And Technology Transfer Capacity Building, Stanley Kowalski, Aarushi Gupta, Ifica Mehra Jan 2014

Overcoming India’S Food Security Challenges: The Role Of Intellectual Property Management And Technology Transfer Capacity Building, Stanley Kowalski, Aarushi Gupta, Ifica Mehra

Law Faculty Scholarship

The growth of the Indian economy after Independence has had little impact on the food security of the country. The paper analyses the development of advanced crop varieties through the use of agricultural technologies (hereinafter "agbiotech") within the technology transfer system, a framework which comprises of the interactions of intellectual property rights law and agricultural research and development in India. Through this, the author argues that agricultural innovation in India is failing due to the absence of connections within the technology transfer system and advocates for the creation of a national program aimed at advancing IP and tech-transfer capacity in …


Economics Of Residue Harvest: Regional Partnership Evaluation, David W. Archer, David J. Muth Jr., Jacob J. Jacobson, Douglas L. Karlen Jan 2012

Economics Of Residue Harvest: Regional Partnership Evaluation, David W. Archer, David J. Muth Jr., Jacob J. Jacobson, Douglas L. Karlen

David J. Muth

Economic analyses on the viability of corn (Zea mays, L.) stover harvest for bioenergy production have largely been based on simulation modeling. While some studies have utilized field research data, most field-based analyses have included a limited number of sites and a narrow geographic distribution. An Iowa case study is developed illustrating the use of data extracted from a database of geographically distributed field studies for a region-specific economic analysis. The analysis utilizes grain and residue yield and associated management information from two Iowa field research sites that are Sun Grant Regional Partnership locations associated with the Corn Stover Regional …

David J. Muth

Advanced biofuels will be developed using cellulosic feedstock rather than grain or oilseed crops that can also be used for food and feed. To be sustainable, these new agronomic production systems must be economically viable without degrading the soil and other natural resources. This review examines six agronomic factors that collectively define many of the limits and opportunities for harvesting crop residue for biofuel feedstock in the midwestern United States. The limiting factors include soil organic carbon, wind and water erosion, plant nutrient balance, soil water and temperature dynamics, soil compaction, and off-site environmental impacts. These are discussed in relationship …

Quantifying Total And Sustainable Agricultural Biomass Resources In South Dakota—A Preliminary Assessment, Kurt A. Rosentrater, Dennis Todey, Russell Persyn Jan 2009

Quantifying Total And Sustainable Agricultural Biomass Resources In South Dakota—A Preliminary Assessment, Kurt A. Rosentrater, Dennis Todey, Russell Persyn

Kurt A. Rosentrater

Conversion of biomass is considered the next major advance in biorenewable fuels, energy, and products. Wholesale conversion to biomass utilization could result in removal of current crop residues from agricultural fields (on prime agricultural lands) or even implementation of different crops and cropping strategies (i.e., switchgrass on marginal lands). To date, the driver for biomass processing has been economics and limitations on the conversion of the lignocellulose. Over the last forty years significant investments and resultant changes in management practices in the agricultural sector have focused on soil and water conservation. One of the major efforts has focused on conservation-till …
