The two-third of the city-dwelling world population by 2050 poses numerous global challenges in the infrastructure and natural resource management domains (e.g., water and food scarcity, increasing global temperatures, and energy issues). The IoT with integrated sensing and communication capabilities has the strong potential for the robust, sustainable, and informed resource management in the urban and rural communities. In this chapter, the vital concepts of sustainable community development are discussed. The IoT and sustainability interactions are explained with emphasis on Sustainable Development Goals (SDGs) and communication technologies. Moreover, IoT opportunities and challenges are discussed in the context of sustainable community …
Public Perception Of Different Planting Techniques Using Augmented Reality, Sultana Quader Tania
Public Perception Of Different Planting Techniques Using Augmented Reality, Sultana Quader Tania
Electronic Theses and Dissertations
The objective of this study was to measure public perception of the different planting techniques (block and matrix), which are used at visitor information centers (VICs) and other rights of way (ROW) areas. The main factors that affect public perception of planting techniques were identified through an extensive literature review and qualitative survey from four welcome centers in the state of Georgia. The ranking of those indicators, based on public preferences, was discovered through a quantitative survey. During the first phase of the quantitative survey, images of block and matrix were used. An iOS-based user-friendly and cost-effective augmented reality (AR) …
Biophysical And Socioeconomic Impacts Of Farmer Managed Natural Regeneration In Burkina Faso, Basnewende Brice Fulgence Zoungrana
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 …
Strategies To Improve Forage Utilization By Sheep Offered Forage Mixtures, Valens Niyigena
Strategies To Improve Forage Utilization By Sheep Offered Forage Mixtures, Valens Niyigena
Graduate Theses and Dissertations
In the first experiment, alfalfa and novel endophyte-infected tall fescue (NE+) forages were harvested after a killing frost, then mixed to formulate 4 different treatments; alfalfa alone, 67% alfalfa +33% fescue, 33% alfalfa + 67% fescue, or 100% fescue. After 3 months of storage as silage, Dorper ewe lambs (n = 20; mean BW = 34.7 ± 6.65 kg) were fed silage for ad libitum consumption, using 5 animals per treatment. Increasing the proportion of NE+ tall fescue improved (P < 0.05) silage total acids and lactic acid concentrations and decreased silage ammonia concentration. Digestible dry matter and organic matter intake and nitrogen utilization parameters decreased with increasing inclusion of NE+ in diet. In the second experiment, 16 Dorper ewe lambs (41.8 ± 4.61 kg BW) were assigned to 4 different treatments; alfalfa silage alone (0 g/kg; CONT) or alfalfa silage mixed with chopped sericea lespedeza (SL) hay to provide 90 (LOW), 180 (MED), or 270 g/kg SL (HIGH) on a dry matter basis in a randomized complete block design experiment with 2 period to provide 4 observations per treatment for each experimental period. Increasing the proportion of sericea lespedeza in the diet decreased dry matter and organic matter digestibility but did not affect feed intake. Fecal nitrogen (g/kg N intake) increased linearly (P < 0.01) while urinary N (g/ day and g/ kg of N intake) tended to decreased linearly and quadratically (P ≤ 0.1) with increasing the proportion of SL in diet. In the third experiments, 16 gestating Dorper ewe lambs (49.1 ± 4.61 kg BW) were allocated to 4 treatments; alfalfa silage alone (0% g/kg; CONT) or alfalfa silage mixed with lablab purpureus(LP) hay to provide 90 (LOW), 180 (MED), or 270 g/kg LP (HIGH) on a dry matter (DM) basis, in a randomized complete block design experiment with a total 8 replication per treatment. Supplementation of LP in diet increased quadratically (P ≤ 0.04) forage dry matter, organic matter intake, digestible dry matter and digestible organic matter intake (P < 0.05). Nitrogen apparently absorbed and urinary N both decreased linearly (P < 0.01) with adding more LP hay in diet. Harvesting and mixing alfalfa and fescue after a killing frost improved silage fermentation characteristics and supplementation of tannins from SL and polyphenol from LP altered N excretion.
Key words: lablab, sericea lespedeza, alfalfa silage, nitrogen, sheep.

Growing Local: The Role Of Urban Gardening In Fostering Food Security, Sustainability, And Community, Franklin Wagner, Lindsey Payne
Growing Local: The Role Of Urban Gardening In Fostering Food Security, Sustainability, And Community, Franklin Wagner, Lindsey Payne
Purdue Journal of Service-Learning and International Engagement
The downtown center of Lafayette, Indiana is situated in a food desert where access to healthy, nutritious food can be limited. Urban gardens are an effective way to increase access to healthy alternatives while also providing a number of benefits to the surrounding area, including opportunities for community growth, education, and physical activity. In summer 2016, researchers from Purdue University collaborated with Lafayette’s GrowLocal Urban Gardens Network (GrowLocal) to perform a baseline analysis of the current community gardening initiatives, and explore the possibilities for expansion, development, and future community involvement through urban gardening.
Both qualitative and quantitative data collection methods …
Effects Of Stormwater Green Infrastructure On Watershed Outflow: Does Spatial Distribution Matter?, Benjamin Fahy, Heejun Chang
Effects Of Stormwater Green Infrastructure On Watershed Outflow: Does Spatial Distribution Matter?, Benjamin Fahy, Heejun Chang
International Journal of Geospatial and Environmental Research
Green Stormwater Infrastructure (GSI) has become a popular method in urban stormwater management. We examined how spatial distribution of GSI affected rainfall-runoff relationships in a recently developed neighborhood in Gresham, Oregon, USA for the 2017-2018 water year. Runoff ratio, peak discharge, and flashiness were compared under four precipitation scenarios (of differing intensity and duration) and different spatial arrangements of GSI. Distributed GSI reduced runoff ratio (10 - 20%), peak discharge (26 - 68%), and flashiness index (56 - 70%). Distributed GSI outperformed centralized structures for all metrics, reducing runoff ratio (22 - 32%), peak discharge 67 to 69%, and flashiness …

Human Rights, Environmental Justice, Social Justice, Faith Values And Ethics: Building Stronger Partnerships For The Common Good By Understanding The Differences, Theresa Harris, Leanne M. Jablonski, Sarah Fortner, Malcolm Daniels
Biennial Conference: The Social Practice of Human Rights
Partnerships between human rights practitioners, local communities, scientists, engineers, and health professionals have shown potential to address deeply rooted, systemic human rights concerns. These collaborations are essential for achieving the UN Sustainable Development Goals (SDGs), and for engaging the perspectives and expertise of all constituents. However, even when the individuals in these partnerships or the organizations they represent have common goals, their motivations, analyses, and solutions often come from different perspectives. Members of good will can inadvertently alienate one another when attempting to work together. The fields of human rights, social justice, environmental justice, and ethics have each developed their …
Campus-Based Agriculture: The Future Of Food At Gettysburg College, Bryn K. Werley
Campus-Based Agriculture: The Future Of Food At Gettysburg College, Bryn K. Werley
Student Publications
This research investigates various methods for producing food on the campus of Gettysburg College in order to improve food sustainability. The transportation of food contributes to the increased use of fossil fuels, which in turn leads to global warming and climate change. By producing a larger portion of its food on-campus, Gettysburg College could reduce the amount of food transported to the school, thereby lessening the College’s environmental impact. Urban farming techniques, hydroponics, aquaponics, and greenhouse-based agriculture are explored as viable methods for achieving this goal. Examples of the use of these techniques on college campuses are drawn from Allegheny …
