Última Using Carbon Offsets to Fund Agricultural Conservation Practices in a Working-Lands Setting AgEcon Reeling, Carson J.; Gramig, Benjamin M.. The nitrogen cascade concept indicates that agriculture serves as a significant link between emissions of the potent greenhouse gas (GHG) nitrous oxide and losses of nitrate-N to surface waters. Conservation practices have the potential to exploit this link, as their implementation is found to reduce fluxes of GHGs and nonpoint source (NPS) water pollution. Several studies have recognized this link and have documented the potential to improve environmental quality through the use of programs which retire land, the cost of which can be offset by the sale of carbon credits. However, the ability to use land for both agricultural production and environmental conservation is important. As such, this study provides a novel analytical framework that is used...

Ano: 2011 URL: http://purl.umn.edu/103577 Improving Agricultural Irrigation on the Balkhab River, Afghanistan AgEcon Reeling, Carson J.; Mitchell, Peter; Halimi, Ghulam Hazrat; Lee, John G.; Carver, Andrew. In Afghanistan, where 80% of the population is rural, irrigated agriculture is important for satisfying subsistence needs. While most of the irrigated agriculture is fed by diversion canal systems which tap surface flows, legal and physical water infrastructure in the region is generally poor. A math programming model is used to optimize irrigation strategies under different water-availability and policy scenarios. It is found that the construction of a reservoir could increase net revenues to a representative farming community by up to 30%. However, even greater benefits may result from increasing distribution efficiencies, depending on the initial level of conveyance losses. Further, property rights schemes may be implemented to distribute wealth more...
