Computing Opportunity Costs of Growing Local Varieties for On-farm Conservation: Illustrations Using Sorghum Data from Ethiopia AgEcon
Wale, Edilegnaw; Mburu, John G.; Estrella, Jaime.
The recent shift of emphasis to on-farm conservation is driven by its diverse attractive features - participatory nature, dynamic nature, capacity to maintain not only crop diversity but the knowledge that evolves with it, the chance it offers and the challenge it brings to link conservation with farmers' livelihood. To make it operational, placing incentives and removal of perverse incentives are of critical importance. However, before placing sound incentives compatible to farmers' circumstances, the opportunity costs farmers face when using local varieties of public interest should be understood. This paper empirically examines farmers' opportunity costs of maintaining local varieties of sorghum using a household survey data collected from 198 sorghum...

ECONOMICS OF SEQUESTERING CARBON IN THE U.S. AGRICULTURAL SECTOR AgEcon
Lewandrowski, Jan; Peters, Mark; Jones, Carol Adaire; House, Robert M.; Sperow, Mark; Eve, Marlen; Paustian, Keith H..
Atmospheric concentrations of greenhouse gases can be reduced by withdrawing carbon from the atmosphere and sequestering it in soils and biomass. This report analyzes the performance of alternative incentive designs and payment levels if farmers were paid to adopt land uses and management practices that raise soil carbon levels. At payment levels below $10 per metric ton for permanently sequestered carbon, analysis suggests landowners would find it more cost effective to adopt changes in rotations and tillage practices. At higher payment levels, afforestation dominates sequestration activities, mostly through conversion of pastureland. Across payment levels, the economic potential to sequester carbon is much lower than the technical potential reported in...
