A review of potential economic mineral resources in offshore Nigeria OceanDocs
Ibe, A.C..
Previously published data and preliminary indications from research now in progress suggest the possible occurrence in offshore Nigeria of economically viable deposits of placer minerals (including heavy minerals), sand and gravel, phosphorite, glauconite, polymetalic manganese nodules etc. In addition, new stratigraphic evidence indicates the existence of potentially rich petroleum plays associated with a Tertiary canyon system in water depths beyond the limits of present exploitation. Based on the comparative geology of similar occurrences in better explored continental margins and ocean basins elsewhere, the possible origin, abundance and distribution of these resources are adduced. A brief assessment of the technology relevant to their discovery and...

Nagaraj, N.; Pradhani, Umesh; Chengappa, P.G.; Basavaraj, G.; Kanwar, Ramesh S..
This study has estimated the supply augmentation of groundwater recharge due to creation of water harvesting structures and has assessed the cost-effectiveness of rainwater harvesting for groundwater recharge on watershed basis in one of the sub-watersheds of the Kolar district, Peninsular India — a typically hard-rock area. The study is based on the primary data for the year 2008-09 collected from a sample of 90 farmers having irrigation bore-wells in the selected watershed named Thotli. The study has indicated that the annual draft of irrigation water exceeds the annual recharge, causing a negative balance. On an average, the returns per rupee investment have been found to be ` 1.80 on farm pond, ` 1.78 on recharge pit and ` 1.39 on field bund. The cost...

ECONOMIC FEASIBILITY OF BIODIESEL PRODUCTION IN NORTH DAKOTA AgEcon
Vanwechel, Tamara; Gustafson, Cole R.; Leistritz, F. Larry.
The U. S. biodiesel industry is rapidly expanding due to energy production concerns, environmental concerns, and recent legislation. The most common type of biodiesel in the United States is derived from soybean oil. Soybeans are a major crop in North Dakota and could easily supply a 5 million gallon per year biodiesel facility. Potential market segments of a biodiesel facility in North Dakota include agriculture, construction, and state fleet sectors based on current diesel use. However, with existing technology and no subsidy, biodiesel operation and investment costs for a North Dakota facility are not competitive with petroleum diesel. Using soybean oil prices of 17 cents to 25 cents per pound, the per gallon cost of producing diesel in...

Economic feasibility of converting cow manure to electricity: A case study of the CVPS Cow Power program in Vermont AgEcon
Wang, Qingbin; Thompson, Ethan; Parsons, Robert L.; Rogers, Glenn.
A case study of the Central Vermont Public Service Corporation (CVPS) Cow Power program examines the economic feasibility for dairy farms to convert cow manure into electricity via anaerobic methane digestion. The study confirms that it is technically feasible to convert cow manure to electricity on dairy farms but the economic returns highly depend on the base electricity price paid by CVPS, premium rate paid by CVPS customers, financial supports from government agencies and other organizations, and sales of the by-products of methane generation. Lessons learned from this program will be useful to other dairy farms and communities interested in converting cow manure into electricity.

Economic Feasibility of Kenaf Production in Three Tennessee Counties AgEcon
Bazen, Ernest F.; Roberts, Roland K.; English, Burton C..
Since the 1940s, kenaf has been viewed as a potential source of fiber, mainly for newsprint and high quality paper. Kenaf research has once again risen to the forefront due to the recent USDA tobacco buyout. Many states and farmers dependent upon tobacco revenues have been seeking alternative crops for a number of years. This study seeks to expand the current literature by examining the economic feasibility of growing kenaf within three counties in Tennessee. Nitrogen meta-yield response functions for kenaf and four traditional crops were developed for 30 soils through crop growth simulation modeling and used to compare optimal crop budgets for each soil. Results reveal that kenaf would not compete favorably with traditional crops on any soil at prices...

Economic Feasibility of Sustainable High Oilseed-Based Biofuel Production: The Case for Biodiesel in North Carolina AgEcon
Yeboah, Anthony K.; Naanwaab, Cephas B.; Yeboah, Osei-Agyeman; Owens, John Paul; Bynum, Jarvetta S..
We assess the economic feasibility of a 10 MMGY biodiesel plant using a Monte Carlo Cash Flow model programmed in Excel using @Risk, a simulation and risk analysis software. The model incorporates stochastic components to capture uncertainty in the analysis. The stochastic components are mainly variables that may exhibit risk, such as input prices, output prices, and expected revenues, and these are assigned probability distributions in the model. The model is programmed with three output variables: stream of revenues, profits/loss, and the resulting net present value (NPV) over ten year forecast period. Results from the cash flow analysis show that average expected revenues from the sale of biodiesel and co-products will be $48.5 million and total...

Economics of Alternative Crop Production in Arid Regions AgEcon
Curtis, Kynda R.; Bishop, Carol; Harris, Thomas R..
As water resources in arid regions decline, agricultural producers are encouraged to adopt water conserving strategies. The implementation of alternative low-water use crops is one option, but is it economically feasible? Data on current and alternative crops for this study include enterprise budgets, producer interviews, and field trials in Northwestern Nevada, USA. We use WinEPIC, a Windows-based version of the EPIC model, which synthesizes both agronomics and economics, to model yields and returns of alternative crop production under differing irrigation levels. Risk analysis or the distribution of net returns to alternative crop production is also examined. This study determined that there are alternative crops that could be feasibly substituted for...

Economics of Meat Production from the Springbuck in the Eastern Cape Karoo AgEcon
Dlamini, Thula S.; Fraser, Gavin C.G..
The feasibility of springbuck based meat production in the EC Karoo was analysed through a stochastic budgeting model, while overtly taking cost and price risk into consideration. Monte Carlo simulation of a springbuck based meat production enterprise was used to quantify the risks that would be faced by springbuck ranchers. Springbuck ranching has been proven a viable alternative in the production of highly nutritious and healthy meat (venison) that is on high demand in European markets and more recently with a promising and growing local demand as well. The results indicate that in the Eastern Cape Karoo, springbuck ranching for meat production is a viable business. As the call for more environmentally friendlier rangelands utilisation economic systems...
