Building Global Leaders Through Field Research And Extension Experiences In Belize, Tom Gill, Adam S. Willcox
Building Global Leaders Through Field Research And Extension Experiences In Belize, Tom Gill, Adam S. Willcox
Journal of International Agricultural and Extension Education
One of the most complex agricultural and natural resources challenges of our time is reconciling sustainable global food security and biodiversity conservation. Providing undergraduate students effective, learning experiences to develop technical and cultural competency prepares them to address this challenge and become global leaders in their disciplines. A three-year experiential research and extension project brought together 14 students and 10 faculty mentors to investigate smallholder farmers practicing conservation-compatible adjacent to the Vaca Forest Reserve in Belize. We used an agroecological approach to foster systems-level thinking and develop transdisciplinary skills of undergraduate students. Students completed applied individual research projects that explored …
Revisiting Participatory Rural Appraisal (Pra) Related Studies And Exploring Pra's Success Determinants: A Content Analysis, Raquel Garcia-Agustin
Revisiting Participatory Rural Appraisal (Pra) Related Studies And Exploring Pra's Success Determinants: A Content Analysis, Raquel Garcia-Agustin
Journal of Public Affairs and Development
Participatory Rural Appraisal (PRA) has shown that participation in development programs in poor communities can be empowering not only for the community members but also for the development workers. However, not all PRAs have seen successes especially in fulfilling their mission to encourage real participation. Hence, it is imperative to understand whether PRA has led to adequate understanding of indigenous perspective to call for action and the interest PRA serves. This analysis aims to provide critical insights and reflections from the experiences of previously conducted PRAs. It further aims to reveal whether PRAs were used effectively and successfully according to …
The Intersection Of Deforestation And Economic Growth In The Brazilian Amazon, Victoria Oceguera
The Intersection Of Deforestation And Economic Growth In The Brazilian Amazon, Victoria Oceguera
Student Theses 2015-Present
Abstract
As a result of capital gain, deforestation of the Amazon in Brazil continues. Brazilian government's insufficient efforts to mitigate and enforce the preservation of these precious forests has ledto the commodification of the Amazon. Chapter 1 uses historical and quantitative data to examine the negative impacts of deforestation on indigenous communities and climate change. Chapter2 employs economics to analyze the role of business as a crucial component of deforestation in Brazil. Chapter 3 engages politics in Brazil to discuss interactions between key actors involved in the perpetuation of deforestation. Chapter 3 examines the interactions between politics and corruption involved …
Lepidopteran Diversity And Abundance Across Five Different Indigenously Managed Land Use Zones In The Naso-Teribe Territory, Bocas Del Toro Province, Panama, Eli Dotson
Independent Study Project (ISP) Collection
Lepidopterans, the order that includes both moths and butterflies, are among the best-known insects taxonomically and ecologically due to the relative ease of monitoring them in comparison to other groups of insects. Their distribution follows that of other insects and forms of life, as around 90% of species have a tropical distribution. This incredibly speciose group of animals fills many vital roles in the ecosystems they inhabit, including herbivores in their larval stages, prey for a variety of predators in all life stages, and pollinators for many plant species as adults. In some circumstances, certain species may also serve as …
Furniture Design And Product Development Principles Considering End-Of-Life Options And Design For Environment Strategies, Mesut Uysal
Open Access Theses
During last decades, environmental issues come into prominence and some governmental or organizational regulations are legislated to reduce environmental impacts of products within their life cycle. At the same time, costumers consider not only price, quality, branding, uniqueness, availability but also environmental impact, safety, and overall sustainability of products they select. Therefore, producers are addressing environmental impact of products they are producing and also making changes to their production process. This project is addressing End-of-Life (EoL) Options of wooden furniture. ^ Although wood is eco-friendly and natural material, its technological process, use and disposal might have ecological problem and challenge. …
Genetic Comparison Between Natural And Planted Populations Of Pinus Brutia And Cupressus Sempervirens In Syria, Batoul N. Al-Hawija, Viktoria Wagner, Isabell Hensen
Genetic Comparison Between Natural And Planted Populations Of Pinus Brutia And Cupressus Sempervirens In Syria, Batoul N. Al-Hawija, Viktoria Wagner, Isabell Hensen
Turkish Journal of Agriculture and Forestry
There is wide consensus that ongoing deforestation contributes to global warming and poses a threat to species diversity. Less understood is whether the practice of creating plantations might also erode genetic diversity and undermine the genetic structure of tree populations. We tested these hypotheses in natural and planted populations of Pinus brutia Ten. subsp. brutia and Cupressus sempervirens L. var. horizontalis (Mill.), 2 important forestry species in the Mediterranean region. We used plant material from 3 different bioclimatic regions in Syria. Using RAPD markers, we evaluated the genetic diversity and structure of 12 populations of P. brutia (6 natural, 6 …
Influence Of Soil Chemical Properties On Relative Abundance Of Arbuscular Mycorrhiza In Forested Soils In Malaysia, Kian Huat Ong, John Keen Chubo, Jie Hung King, Chia Shing Lee, Dennis Shan An Su, Philip Sipen
Influence Of Soil Chemical Properties On Relative Abundance Of Arbuscular Mycorrhiza In Forested Soils In Malaysia, Kian Huat Ong, John Keen Chubo, Jie Hung King, Chia Shing Lee, Dennis Shan An Su, Philip Sipen
Turkish Journal of Agriculture and Forestry
The effect of soil chemical properties on the diversity and colonization of arbuscular mycorrhiza (AM) varies among ecosystems. This study was conducted to assess and compare the abundance of AM in a rehabilitated forest and a logged-over forest soil using the most probable number and spore number methods. Glomus (71.7%-82.1%) and Acaulospora (17.4%-19.5%) were found to be abundant in both sites, while Gigaspora was found only in the logged-over forest. The abundance of AM in the rehabilitated forest based on the spore count was significantly higher than in the logged-over forest by a 6-fold difference. Furthermore, root colonization in the …
Spatial Distribution Of Human Elephant Conflict (Hec) And Characterization Of Crop-Raiding Elephants In Kasigau Region, Kenya, Simon Kasaine Kagwa
Spatial Distribution Of Human Elephant Conflict (Hec) And Characterization Of Crop-Raiding Elephants In Kasigau Region, Kenya, Simon Kasaine Kagwa
Masters Theses & Specialist Projects
Human-elephant conflict (HEC) is complex and a serious elephant conservation concern across Africa and Asia where elephants are found. HEC occurs whenever people and elephants share common interests. For HEC to be ameliorated and elephant conservation to be successful locally and regionally, the distribution and implications of HEC should be understood. The purpose of this study was to determine the spatial distribution of HECs and characterize elephant herds in terms of herd size responsible for crop-raiding in Kasigau. The study was generally guided by two working a priori hypotheses: (1) farms near the bush edge or livestock watering points will …
