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 …

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 …

The Differentiation Of Smallholder Farming And Household Food Responsibilities In Northern Ghana, Siera Vercillo

Electronic Thesis and Dissertation Repository

One of the most urgent problems facing sub-Saharan Africa is that many people lack access to safe, nutritious, and culturally appropriate food, particularly in semi-arid regions such as northern Ghana. An important indication of this problem within Ghana is that stunting rates due to prolonged undernourishment are significantly higher in the northern regions than in other parts of the country, despite claims of an overall increase in the availability of food. Broadly, this dissertation employs qualitative case study research in the Northern Region (interviews N=109 and 12 focus groups) to describe the changes in access to resources, roles and …

Coffee Agroecology, Food Sovereignty, And Agrarian Livelihoods In Puerto Rico, Ileana I. Diaz

Electronic Thesis and Dissertation Repository

This research investigates whether coffee can play a role in building food sovereignty in Puerto Rico as well as how farmers perceive the effects of growing coffee agroecologically on their livelihoods. The most important contribution of this research is to raise and answer the question of whether a cash crop such as coffee can be part of a food sovereignty strategy. I conducted 18 semi-structured interviews with farmers in Puerto Rico. The findings indicate that agroecological farmers in Puerto Rico believe that growing coffee is an important part of pursuing food sovereignty - which is the framework they used to …

Impact Of Agroecology Adoption, Migration And Remittance Receipt On Household Welfare, Joseph Kangmennaang

Electronic Thesis and Dissertation Repository

This thesis aims to examine the impact of two livelihood strategies on household wellbeing in Northern and Central Malawi. Specifically, the study aims to examine how agroecology adoption, migration and remittance receipt impact household food security and asset poverty levels. Prior research has revealed that agroecological farming methods and remittance receipt can increase productivity, yield stability and resilience of family farmers as well as increase their incomes and propel them out of poverty. Agroecology as an alternative agricultural approach has gained momentum through some high-level FAO meetings as well as reports highlighting its potential. Migration and remittances flows have also …

The Money Of Qaroon And The Patience Of Ayoub: Women And Land In Egypt's Mubarak Resettlement Scheme, Dina Najjar

Electronic Thesis and Dissertation Repository

This dissertation addresses the challenge of achieving increased empowerment and equality for Egyptian women. The dissertation tests the assumption that land access (through both joint and full titles) increases empowerment and equality for women in two desert resettlements of Sa’yda and Intilaq, part of the massive Mubarak Resettlement Scheme (MRS). In particular, the dissertation identifies: 1) how land access could empower Egyptian women and 2) women’s experiences with land access in the MRS. Findings reveal that land access is indeed the most promising route for women’s advancement in life, but the desert land required patience and financial assets. Land access, …
