A time to change? The supply of climate mitigation products from land-use change in northern NSW AgEcon
Moss, Jonathan; Cacho, Oscar J.; Mounter, Stuart W..
With the impending introduction of an Australian Carbon Pollution Reduction Scheme, farmers and landholders in rural Australia have increased opportunities to participate in the market. This includes the adoption of land-use change to sequester additional carbon in exchange for carbon credits and the production of a renewable energy source (biofuels). However, these land-use changes compete with existing farm enterprises and may contain significant transaction costs. Therefore it is necessary for the institutional arrangements to provide adequate incentives for landholders to adopt these land-use changes. This paper examines the potential supply of these land-use changes for climate mitigation from landholders in a northern NSW catchment. These results...

Agricultural Land Tenure and Carbon Offsets AgEcon
Claassen, Roger; Morehart, Mitchell J..
Agricultural Land Tenure and Carbon Offsets examines the potential role that land ownership might play in determining the agricultural sector’s involvement in carbon sequestration programs. By estimating the carbon sequestration potential of agricultural producers who own most of the land they operate, this report finds that land ownership should not be a constraining factor in agriculture’s ability to provide carbon offsets.

Agriculture and the WTO: Future Directions in the Grain and Oilseed Sectors AgEcon
Gray, Richard S..
This paper examines the larger economic forces that shape multilateral trade agreements and concludes that further WTO trade reform in the grain and oilseed sectors will be difficult to achieve. The somewhat successful Uruguay Round had budget and internal reform pressure to assist the process. The United States currently has large budget surpluses, and efficiency effects from policy reform following the Uruguay Round have reduced the possible gains from further domestic reform. Without these pressures, further negotiated reform in the grain and oilseed sectors is a remote possibility. On the other hand, there are good prospects for a multilateral environmental agreement on climate change. Ratification of a climate change agreement could have a large...

An Economic Analysis of Carbon Sequestration for Wheat and Grain Sorghum Production in Kansas AgEcon
Aller, Taryn D.; Williams, Jeffery R.; Nelson, Richard G.; Claassen, Mark M.; Rice, Charles W..
This study examined the economic potential with and without carbon credit payments of two crop and tillage systems in South Central Kansas that could reduce carbon dioxide emissions and sequester carbon in the soil. Experiment station cropping practices, yield data, and soil carbon data for continuously cropped wheat and grain sorghum produced with conventional tillage and no-tillage from1986 to 1995 were used to determine soil carbon changes and to develop enterprise budgets to determine expected net returns for a typical dryland farm in South Central Kansas. No-till had lower net returns because of lower yields and higher overall costs. Both crops produced under no-till had higher annual soil C gains than under conventional tillage. Carbon credit...

Assessing the economic impact of an emissions trading scheme on agroforestry in Australia’s northern grazing systems AgEcon
Donaghy, Peter; Rolfe, John; Gowen, Rebecca; Bray, Steven; Madonna, Hoffman.
Although agriculture generates a significant portion of Australia’s greenhouse gas emissions, it also has the potential to sequester large quantities of emissions through changed land use management such as agroforestry. Whilst there is an extensive amount of agroforestry literature, little has been written on the economic consequences of adopting silvopastoral systems in northern Australia. This paper reports the economic feasibility of adopting complimentary agroforestry systems in the low rainfall region of northern Australia. The analysis incorporates the dynamic tradeoffs between tree and pasture growth, carbon sequestration, cleared regrowth decomposition rates and livestock methane emissions in a bioeconomic model. The results suggest there are...

BIOCHAR: PYROGENIC CARBON FOR AGRICULTURAL USE - A CRITICAL REVIEW Rev. Bras. Ciênc. Solo
Novotny,Etelvino Henrique; Maia,Claudia Maria Branco de Freitas; Carvalho,Márcia Thaís de Melo; Madari,Beáta Emöke.
Biochar (carbonized biomass for agricultural use) has been used worldwide as soil amendment and is a technology of particular interest for Brazil, since its "inspiration" is from the historical Terra Preta de Índios(Amazon Dark Earth), and also because Brazil is the world's largest charcoal producer, generating enormous residue quantities in form of fine charcoal and due to the availability of different residual biomasses, mainly from agroindustry (e.g., sugar-cane bagasse; wood and paper-mill wastes; residues from biofuel industries; sewage sludge etc), that can be used for biochar production, making Brazil a key actor in the international scenario in terms of biochar research and utilization). In the last decade, numerous studies on biochar have been...

Biological Carbon Sinks: Transaction Costs and Governance AgEcon
van Kooten, G. Cornelis.
Activities that remove CO2 from the atmosphere and store it in forest and agricultural ecosystems can generate CO2-offset credits that can thus substitute for CO2 emissions reduction. Are biological CO2-uptake activities competitive with CO2 offsets from reduced fossil fuel use? In this paper, it is argued that transaction costs impose a formidable obstacle to direct substitution of carbon uptake offsets for emissions reduction in trading schemes, and that separate caps should be set for emissions reduction and sink-related activities. While a tax/subsidy scheme is preferred to emissions trading for incorporating biologically-generated CO2 offsets, contracts that focus on the activity and not the amount of carbon sequestered are most likely to lead to the...

Carbon Accumulation in Pinus taeda Estimated by X-rays Densitometry and Trunk Analysis PFB - Pesquisa Florestal Brasileira
Bellote, Antonio Francisco Jurado; Dedecek, Renato Antonio; Lavoranti, Osmir José; Tomazello Filho, Mario de Castro; Andrade, Guilherme de Castro.
The objective of this work was to evaluate Pinus aeda growth and based on X-ray methods of  densitometry and bole analyses to develop mathematical models to estimate carbon amount accumulated on trees of different ages varying on DBH. Five P. taeda plantations were selected on sites of different soils, thinning intensity and growing rate. On each site dominant trees were selected and discs cuts from different heights were collected and submitted to X-ray densitometry for trunk analyses. Mathematical models were developed, to generated equations to compare by testing their statistical identity and equality and to validate by bootstrap methods. The results showed that P. taeda productivity was influenced by soil and silvicultural practices; X-ray...

Carbon concentration in structures of Arctostaphylos pungens HBK: An alternative CO2 sink in forests Phyton
Pompa-García,M; Jurado,E.
Arctostaphylos pungens HBK is a dominant species with increasing abundance and distribution in chaparral ecosystems as a result of range management and, possibly, changes in climate. The value of this species for carbon (C) sequestration is unknown, and the standard 50% C out of total tree biomass is used as an approximate value. In this study, we aim to determine the C concentration of the primary components of A. pungens. The total C expressed as a percentage of biomass was determined with a Solids TOC Analyzer. We found the C concentration to vary among components. Leaves exhibited the highest C concentration (51.70%). Roots (46.11%), stems (47.30%), fruits (47.89%) and twigs (48.40%) had similar C concentration. These results provided superior...

CARBON SEQUESTRATION, CO-BENEFITS, AND CONSERVATION PROGRAMS AgEcon
Feng, Hongli; Kling, Catherine L.; Gassman, Philip W..
Land use changes to sequester carbon also provide "co-benefits," some of which (for example, water quality) have attracted at least as much attention as carbon storage. The non-separability of these co-benefits presents a challenge for policy design. If carbon markets are employed, then social efficiency will depend on how we take into account co-benefits, that is, externalities, in such markets. If carbon sequestration is incorporated into conservation programs, then the weight given to carbon sequestration relative to its co-benefits will partly shape these programs. Using the Conservation Reserve Program (CRP) as an example, we show that CRP has been sequestering carbon, which was not an intended objective of the program. We also demonstrate that more...

Carbon stock and its compartments in a subtropical oxisol under long-term tillage and crop rotation systems Rev. Bras. Ciênc. Solo
Campos,Ben-Hur Costa de; Amado,Telmo Jorge Carneiro; Bayer,Cimélio; Nicoloso,Rodrigo da Silveira; Fiorin,Jackson Ernani.
Soil organic matter (SOM) plays a crucial role in soil quality and can act as an atmospheric C-CO2 sink under conservationist management systems. This study aimed to evaluate the long-term effects (19 years) of tillage (CT-conventional tillage and NT-no tillage) and crop rotations (R0-monoculture system, R1-winter crop rotation, and R2- intensive crop rotation) on total, particulate and mineral-associated organic carbon (C) stocks of an originally degraded Red Oxisol in Cruz Alta, RS, Southern Brazil. The climate is humid subtropical Cfa 2a (Köppen classification), the mean annual precipitation 1,774 mm and mean annual temperature 19.2 ºC. The plots were divided into four segments, of which each was sampled in the layers 0-0.05, 0.05-0.10, 0.10-0.20, and...

Climate Change Legislation: Positive or Negative For North Dakota Agriculture? AgEcon
Taylor, Richard D.; Koo, Won W..
The United States House of Representatives passed a climate change bill entitled “The American Clean Energy and Security Act” in June 2009. The bill establishes a combined efficiency and renewable electricity standard which requires retail electricity suppliers to utilize 20% renewable energy by 2020. The objective of this study is to estimate the costs of the American Clean Energy and Security Act in crop production and the benefits of carbon sequestration under the legislation. This study especially evaluates the impact of the legislation on the North Dakota farm income under a Cap and Trade system with and without carbon sequestration. Three different carbon sequestration programs are evaluated to estimate the impact of each program on the net farm...

Contrasts in Areas of Rubber Tree Clones in Regard to Soil and Biomass Carbon Stocks Rev. Bras. Ciênc. Solo
Diniz,Anderson Ribeiro; Pereira,Marcos Gervasio; Balieiro,Fabiano de Carvalho; Silva,Eduardo Vinicius da; Santos,Felipe Martini; Lisboa,Francy Junio Gonçalves; Oliveira,Aldo Bezerra de; Cruz,Renato Barbosa da.
ABSTRACT Rubber tree (Hevea brasiliensis) crop may accumulate significant amounts of carbon either in biomass or in the soil. However, a comprehensive understanding of the potential of the C stock among different rubber tree clones is still distant, since clones are typically developed to exhibit other traits, such as better yield and disease tolerance. Thus, the aim of this study was to address differences among different areas planted to rubber clones. We hypothesized that different rubber tree clones, developed to adapt to different environmental and biological constrains, diverge in terms of soil and plant biomass C stocks. Clones were compared in respect to soil C stocks at four soil depths and the total depth (0.00-0.05, 0.05-0.10, 0.10-0.20,...

Designing Contracts for Reducing Emissions from Deforestation and Forest Degradation AgEcon
Cordero Salas, Paula.
Reduction of carbon emissions from deforestation and forest degradation (REDD) has been identified as a cost effective element of the post-Kyoto strategy to achieve long-term climate objectives. The success of REDD depends primarily on the design and implementation of a financial mechanism that provides land-holders sufficient incentives to participate in a REDD scheme. This paper proposes relational contracting as a more appropriate framework for analyzing proposed REDD incentive regimes rather than that of complete contracting enforcement because relational contracting relies upon mutual self-enforcement in a repeated transaction framework, which better suits the stylized facts of REDD. We characterize the optimal REDD relational contract and provide the...

Economic and Environmental Co-benefits of Carbon Sequestration in Agricultural Soils: Retiring Agricultural Land in the Upper Mississippi River Basin AgEcon
Feng, Hongli; Kurkalova, Lyubov A.; Kling, Catherine L.; Gassman, Philip W..
This study investigates the carbon sequestration potential and co-benefits from policies aimed at retiring agricultural land in the Upper Mississippi River Basin, a large, heavily agricultural area. We extend the empirical measurement of co-benefits from the previous focus on environmental benefits to include economic transfers. These transfers have often been mentioned as a co-benefit, but little empirical work measuring the potential magnitude of these transfers has previously been undertaken. We compare and contrast five targeting schemes, each based on maximizing different physical environmental measures, including carbon sequestration, soil erosion, nitrogen runoff, nitrogen leaching, as well as the area enrolled in the program. In each case, the...

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...
