Socio-Environmental Considerations At The Usuma Reservoir In Abuja, Nigeria, Fanan Ujoh Mr, James Ikyernum Mr, Olarewaju O. Ifatimehin Dr

Dr. Fanan Ujoh

Reservoirs are Man’s attempt towards water re-distribution from regions/seasons of abundance/surplus to regions/seasons of scarcity. This study focuses on socio-environmental impacts of the Lower Usuma dam in Abuja, on its four surrounding communities. Stratified random sampling technique was employed in the administration of a questionnaire to 200 respondents. Using descriptive statistics and the student t-test for the analysis, the study discovered that: (i) there has been no significant improvement in infrastructure provision by Government; (ii) cases of water-borne diseases are high; (iii) the communities have lost land for cultivation; and, (iv) the communities believe that the resettlement scheme is not …

A Survey Of Seafood Traceability And Sustainability In The United States— Processes, Regulations, And Current Initiatives, Nancy A. Olsen

Working Papers

The global seafood industry currently lacks a standardized, widespread method to easily trace the chain of custody of products that they purchase. With global overfishing leading to declining fish stocks around the world, it is vital for seafood providers to have the ability to identify and buy products from sustainable fisheries that are well managed, target abundant species, and fish in environmentally responsible ways. This paper analyzes public and private initiatives that seek to provide product traceability. In summarizing the current status of seafood traceability, stakeholders agree that are a number of challenges with trying to piece together so many …

Agricultural Efficiency And The End Of The Oil Age; Building A Future Of Longevity, Keith Mchugh

Pomona Senior Theses

This thesis uses an efficiency analysis of agricultural systems to assert that, in lieu of rising prices of fossil fuel, people need to come into more direct contact with their food systems. With a switch to smaller, more efficient farms that rely less on fossil fuel and are connected with the communities they supply for, we can avoid an energy crisis turning into a famine. These smaller-scale systems can help create self-contained, carbon-neutral communities.

Roger Williams Park Edible Forest Garden, Mark S. Scialla

Senior Honors Projects

An edible forest garden is a low-maintenance system that uses edible native and regionally-adapted plants arranged in beneficial relationships to meet human, wildlife and ecosystem needs. The forest garden in Roger Williams Park will transform underutilized urban land into a highly productive parcel producing market-viable fruits, nuts, vegetables, medicine and fiber. Forest gardens mimic natural forest systems in architecture and complexity. The design follows ecological principles to create a system that promotes biodiversity and enhances the surrounding ecosystem. This project also demonstrates the potential to grow food and create land-based livelihoods in the city.

Phosphorus In Phoenix: A Budget And Spatial Representation Of Phosphorus In An Urban Ecosystem, Genevieve S. Metson, Rebecca L. Hale, David M. Iwaniec, Elizabeth M. Cook, Jessica R. Corman, Christopher S. Galletti, Daniel L. Childers

School of Natural Resources: Faculty Publications

As urban environments dominate the landscape, we need to examine how limiting nutrients such as phosphorus (P) cycle in these novel ecosystems. Sustainable management of P resources is necessary to ensure global food security and to minimize freshwater pollution. We used a spatially explicit budget to quantify the pools and fluxes of P in the Greater Phoenix Area in Arizona, USA, using the boundaries of the Central Arizona– Phoenix Long-Term Ecological Research site. Inputs were dominated by direct imports of food and fertilizer for local agriculture, while most outputs were small, including water, crops, and material destined for recycling. Internally, …
