- Economic potential for soil carbon sequestration in the Nioro region of Senegal's Peanut BasinDiagana, B.; Antle, J.; Stoorvogel, J.; Gray, K. (Elsevier Ltd, 2007)This paper discusses a study that used biophysical and economic simulation models to assess farmers' involvement in soil carbon contracts in the Nioro region of Senegal's Peanut Basin. The analysis incorporated climate and soil data with multiple scenarios of fertilizer use and crop residue incorporation to estimate potential for carbon sequestration under different parameters. This provided the basis for simulating carbon payment schemes in which farmers could be paid for applying higher levels of fertilizer and incorporating their crop residues. Although the results suggest that it is possible to sequester marketable amounts of carbon in the Nioro region, there was insufficient data on labor costs, transaction costs, and opportunity costs associated with crop residue incorporation. Thus, data collection before the economic potential for carbon sequestration in the region can be fully assessed and carbon contracts can be developed and implemented.
- Soil carbon sequestration and associated economic costs for farming systems of the Indo-Gangetic Plain: A meta-analysisGrace, P. R.; Antle, J.; Aggarwal, Pramod K.; Ogle, S.; Paustian, Keith; Basso, B. (Elsevier, 2012)Carbon sequestration presents a unique opportunity for nation-states to accumulate monetary credit while promoting soil conservation and ecological sustainability. In this meta-analysis, previously measured data on carbon sequestration rates and local data were used to estimate the potential for carbon sequestration of wheat-based production systems within economic and ecological constraints in the Indo-Gangetic Plains of India. Over twenty years, using no-till practices in wheat-rice, maize-wheat, and cotton-wheat production systems would increase carbon sequestration by 60.7 Mt. However, this estimated differed according to carbon prices offered due to the costs associated with switching to no-till practices. Carbon prices of 200 USD Mg C-1 allowed for the highest amount of sequestration: 79 percent of the potential sequestration amount. Regional success varied, and the authors assert that climate and market imperfections are likely to skew estimations.
