Intra-Field Nitrogen Estimation For Wheat And Corn Using Unmanned Aerial Vehicle-Based And Satellite Multispectral Imagery, Plant Biophysical Variables, Field Properties, And Machine Learning Methods, Jody Seymon Yu

Electronic Thesis and Dissertation Repository

Management of nitrogen (N) fertilizers is an important agricultural practice and field of research to increase productivity, minimize environmental impacts and the cost of production. To apply N fertilizer at the right rate, time, and place depends on the crop type, desired yield, and field conditions. The objective of this study is to use Unmanned Aerial Vehicle (UAV) multispectral imagery, PlanetScope satellite imagery, vegetation indices (VI), crop height, leaf area index (LAI), field topographic metrics, and soil properties to predict canopy nitrogen weight (g/m²) of corn and wheat fields in southwestern Ontario, Canada. Random Forests (RF) and Support …

The authors of the present essay propose here some actions that can efficiently help to the success of …

Climate Change Vulnerability And Perceived Resilience Among Smallholder Farmers In The Upper West Region Of Ghana, Evans Sumabe Batung

Electronic Thesis and Dissertation Repository

Globally, observed climate change has become a major barrier to agricultural productivity. At the same time, present and projected climate impacts are disproportionately affecting smallholder farmers in sub-Saharan Africa (SSA) where smallholder agriculture constitutes the predominant source of livelihood. Due to the vast agricultural potential of SSA, climate change resilience has been central in several multi-level deliberations over the past few decades. However, existing policies aimed at improving the effects of climate change on food security have overwhelmingly focused on the climatic dimensions of vulnerability, resulting in a lack of knowledge of the role non-climatic factors also play in shaping …

To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand

Electronic Theses and Dissertations

Ever since the eighteenth century, experts have tried to tell farmers how to farm. The agricultural enlightenment in Europe marked the beginning of a long arc of new experts aiming to change agricultural knowledge and practice. This dissertation analyzes the pivotal period in the late nineteenth and early twentieth century in Germany and the United States when scientists, improvers, and market agents began to develop comprehensive ways to communicate agricultural innovation to farmers. In a functional approach to analyzing the negotiation of agricultural knowledge through its communication in things, words, and practices, this dissertation argues that the process of change …

Urban Forests And Their Potential To Combat Food Insecurity: Analyzing Foods From Street Trees In New York City, Ny, Kristen Cooney

Environment and Sustainability Summer Fellows

There is growing recognition that urban forests have the potential to combat food insecurity via their edible parts, namely fruits, berries, and nuts. Many tree species commonly planted in urban spaces have edible parts that may fulfill the nutritional needs of city residents that are food insecure, but no one has analyzed the value of city street trees to understand this potential. I analyzed New York City’s street trees by each species and their edible parts to measure this potential.

The Montana Expression 2021: Resident Employment, Relocation, And Outdoor Recreation During Covid-19, Megan Schultz, Carter Bermingham

Institute for Tourism and Recreation Research Publications

This report is a summary of Montana residents and their self-reported use of public lands and waterways during 2020 compared to previous years. Data were collected from January 1st to March 31st of 2021. As a result of the pandemic, the number of people participating in outdoor recreation in certain parts of the country increased significantly – Montana being one of those places. Public lands and waterways, like state and federally managed parks, reported record visitation numbers for some months of 2020. In addition, anecdotal reports from public land managers and tourism partners also suggests that the level of use …

Intangible Cultural Heritage: A Benefit To Climate-Displaced And Host Communities, Gül Aktürk, Martha B. Lerski

Publications and Research

Climate change is borderless, and its impacts are not shared equally by all communities. It causes an imbalance between people by creating a more desirable living environment for some societies while erasing settlements and shelters of some others. Due to floods, sea level rise, destructive storms, drought, and slow-onset factors such as salinization of water and soil, people lose their lands, homes, and natural resources. Catastrophic events force people to move voluntarily or involuntarily. The relocation of communities is a debatable climate adaptation measure which requires utmost care with human rights, ethics, and psychological well-being of individuals upon the issues …

Pulling The Food System Up By The Roots: How Do We Build An Equitable Food System In The Twin Cities?, Aubrey A. Hagen

Geography Honors Projects

Prior to 2020, food insecurity was already a pervasive problem in the United States, with limited access to adequate, nutritious foods being linked to numerous poor physical and psychological outcomes. With the onset of the Covid-19 pandemic and civil uprisings in response to police brutality and state-sanctioned violence, the Twin Cities communities are facing overlapping crises that threaten individual and community wellbeing and food security. How do we build a just, equitable, and “crisis-proof” food system? Drawing from theoretical frameworks in social epidemiology and radical food geography, this paper assesses how the local food system and community food insecurity in …

Human Centeredness: The Foundation For Leadership-As-Practice In Complex Local/Regional Food Networks, Maryann Martinez

Antioch University Full-Text Dissertations & Theses

Our local and regional food systems are predominately modeled on a failed capitalist market-based economy. In the absence of corporate accountability, and/or support on the federal policy level, local and regional leadership and self-organized networks are critical to the scaling across and evolution of a moral and equitable food system. Networked food systems leaders are developing the capacity to solve wicked problems, and spark change. Understanding the values and practices of local food systems leadership that initiate, influence, and support activities is essential to understanding how to foster conditions for local and regional food network growth. My dissertation research is …
