An analysis of the spatial and temporal patterns of greenhouse gas emissions by agriculture in Western Australia and the opportunities for agroforestry offsets AgEcon
Kingwell, Ross S.; Harris-Adams, Keely.
If agriculture is included in an Australian emissions trading scheme then it may face from 2015 at the earliest, a price for its greenhouse gas emissions; and thereby have incentives to offset and lessen its emissions. Yet because there is currently little understanding of the spatial pattern of emissions in agricultural regions of Australia, the extent of the challenge the sector faces in reducing its emissions is not fully recognised. To improve our understanding, this study uses the National Greenhouse Accounts methodology to estimate the spatial and temporal patterns of agricultural emissions since 1990 in the key agricultural region in Australia’s southwest. This region generates almost 40 percent of the nation’s winter crop production and supports...

Can Carbon Sinks Be Operational? RFF Workshop Proceedings AgEcon
Sedjo, Roger A.; Toman, Michael.
An RFF Workshop brought together experts from around the world to assess the feasibility of using biological sinks to sequester carbon as part of a global atmospheric mitigation effort. The chapters of this proceeding are a result of that effort. Although the intent of the workshop was not to generate a consensus, a number of studies suggest that sinks could be a relatively inexpensive and effective carbon management tool. The chapters cover a variety of aspects and topics related to the monitoring and measurement of carbon in biological systems. They tend to support the view the carbon sequestration using biological systems is technically feasible with relatively good precision and at relatively low cost. Thus carbon sinks can be operational.

Carbon Sequestration with Reforestations and Biodiversity-Scenic Values AgEcon
Caparros, Alejandro; Cerda, Emilio; Ovando, P.; Campos, Pablo.
This paper presents an optimal control model to analyze reforestations with two different species, including commercial values, carbon sequestration and biodiversity or scenic values. We solve the model qualitatively with general functions and discuss the implications of partial or total internalization of environmental values, showing that internalizing only carbon sequestration may have negative impacts on biodiversity-scenic values. To evaluate the practical relevance, we compare reforestations in the South-west of Spain with cork-oaks (a slow growing native species) and with eucalyptus (a fast growing alien species). We do the analysis with two different carbon crediting methods: the Carbon Flow Method and the Ton Year Accounting Method. With the...

ECONOMICS OF AGRICULTURAL SOIL CARBON SEQUESTRATION IN THE NORTHERN GREAT PLAINS AgEcon
Antle, John M.; Capalbo, Susan Marie; Mooney, Sian; Elliott, Edward T.; Paustian, Keith H..
Under the Kyoto protocol of the United Nations Framework Convention on Climate Change the United States is charged with reducing emissions of greenhouse gases to seven percent below their 1990 levels by the period 2008-2012. These reductions could be met from many industries including agriculture. In this paper, an economic simulation model is linked to the CENTURY ecosystem model to quantify the economic efficiency of policies that might be used to sequester carbon (C) in agricultural soils in the Northern Great Plains region. Model outputs are combined to assess the costs of inducing changes in equilibrium levels of soil C through three types of policies. The first is a CRP-style policy that provides producers with per-acre payments for converting...

These reductions could be met from many industries including agriculture. In this paper, an economic simulation model is linked to an ecosystem model to quantify the economic efficiency of policies that might be used to sequester carbon (C) in agricultural soils in the Northern Plains region. Simulations with the Century ecosystem model show that long-term soil C levels associated with a crop/fallow system are less than those for grass alone, but that soil C levels for grass-clover-pasture are greater than for continuously cropped...

Estimating Carbon Supply Curves for Global Forests and Other Land Uses AgEcon
Sedjo, Roger A.; Sohngen, Brent; Mendelsohn, Robert.
This study develops cumulative carbon 'supply curves' for global forests utilizing an dynamic timber supply model for sequestration of forest carbon. Because the period of concern is the next century, and particular time points within that century, the curves are not traditional Marshallian supply curves or steady-state supply curves. Rather, the focus is on cumulative carbon cost curves (quasi-supply curves) at various points in time over the next 100 years. The research estimates a number of long-term, cumulative, carbon quasi-supply curves under different price scenarios and for different time periods. The curves trace out the relationship between an intertemporal price path for carbon, as given by carbon shadow prices, and the cumulative carbon...

Forest Carbon Sequestration: Some Issues for Forest Investments AgEcon
Sedjo, Roger A..
A major problem being faced by human society is that the global temperature is believed to be rising due to human activity that releases carbon dioxide to the atmosphere; i.e., global warming. The major culprit is thought to be fossil fuel burning, which is releasing increasing amounts of carbon dioxide in the atmosphere. The problem of increasing atmospheric carbon dioxide can be addressed a number of ways. One of these is forestry and forest management. This paper examines a number of current issues related to mitigating the global warming problem through forestry. First, the overall carbon cycle is described, and the potential impact of forests on the buildup of atmospheric carbon is examined. A major focus is the means by which forests and forest...

Forestry Sequestration of CO2 and Markets for Timber AgEcon
Sedjo, Roger A.; Sohngen, Brent.
Forestry has been considered to have potential in reducing the atmospheric concentration of carbon dioxide by sequestrating carbon in above-ground timber and below-ground roots and soil. This potential has been noted in the Kyoto Protocol, which identified specific forestry activities for which carbon sequestration credits could be obtained. To date, a few forestry efforts have been undertaken for carbon purposes, but most of these efforts have been on a small scale. Proposals have been under discussion, however, that would result in the creation of very large areas of new forest for the purpose of offsetting some of the additional carbon that is being released into the atmosphere. Concerns are expressed, however, that large-scale sequestration operations...

Land-Use Change and Carbon Sinks: Econometric Estimation of the Carbon Sequestration Supply Function AgEcon
Lubowski, Ruben N.; Plantinga, Andrew J.; Stavins, Robert N..
When and if the United States chooses to implement a greenhouse gas reduction program, it will be necessary to decide whether carbon sequestration policies - such as those that promote forestation and discourage deforestation - should be part of the domestic portfolio of compliance activities. We investigate the cost of forest-based carbon sequestration. In contrast with previous approaches, we econometrically examine micro-data on revealed landowner preferences, modeling six major private land uses in a comprehensive analysis of the contiguous United States. The econometric estimates are used to simulate landowner responses to sequestration policies. Key commodity prices are treated as endogenous and a carbon sink model is used to predict changes in...

On the Integration of Carbon Capture and Storage into the International Climate Regime AgEcon
Bode, Sven; Jung, Martina.
As GHG emissions did not decline as anticipated early of the 1990ties Carbon Capture and Storage (CCS) recently gained more and more attention as a climate change mitigation option. However, CO2 suppressed in geological reservoirs is likely to lead to future releases of the CO2 stored. This "non-permanence" must be considered if an environmentally sound policy is desired. Against this background, the present article analyses a potential integration of CCS in the international climate regime. It is based on existing rules and modalities regarding non-permanence of sequestration in the Land use, Land-use change and Forestry (LULUCF) sector. Interestingly, the experience from LULUCF has almost completely been neglected during the discussion on CCS. We argue...

Prospects for Carbon Capture and Storage Technologies AgEcon
Anderson, Soren T.; Newell, Richard G..
Carbon capture and storage (CCS) technologies remove carbon dioxide from flue gases for storage in geologic formations or the ocean. We find that CCS is technically feasible and economically attractive within the range of carbon policies discussed domestically and internationally. Current costs are about $200 to $250 per ton of carbon, although costs are sensitive to fuel prices and other assumptions and could be reduced significantly through technical improvements. Near-term prospects favor CCS for certain industrial sources and electric power plants, with storage in depleted oil and gas reservoirs. Deep aquifers may provide an attractive longer-term storage option, whereas ocean storage poses greater technical and environmental uncertainty. Vast...

The Carbon Challenge for Mixed Enterprise Farms AgEcon
Kingwell, Ross S..
As part of its climate change policy the Australian government has introduced a Mandatory Renewable Energy Target (MRET) scheme and is also attempting to introduce a Carbon Pollution Reduction Scheme (CPRS). Using as a case study a main agricultural region of Australia, this paper examines how farming systems in this region may be affected by the medium term policy settings of these two schemes. A bio-economic model of the region’s farming systems is developed and used to assess the schemes’ impacts on the nature and profitability of the farming systems. Results show a range of profit and enterprise impacts across the range of farming systems. Farms as providers of biomass for electricity generation and small users of electricity are liable to benefit from...
