TECHNO-ECONOMIC ANALYSIS (TEA) AND LIFE CYCLE ASSESSMENT (LCA) OF MAIZE STORAGE FOR SMALL AND MIDDLE SIZED FARMERS CIGR Journal
Rosentrater, Kurt A..
Maize is the most widely cultivated cereal crop worldwide, currently ranked the third most important crop globally after wheat and rice. It is a key staple food in many developing countries. However, maize is produced on a seasonal basis, usually harvest once per year. To maintain a constant supply throughout the year, maize should be properly stored. But this may entail high cost and high-energy consumption, which can contribute significant amounts of greenhouse gas emissions. In this study, three storage capacities (25,000 bu, 250,000 bu and 2,500,000 bu) of maize were evaluated for economic analysis and environmental impact. The results show that the total storage cost per bushel decreased as storage capacity increased (3.68$/bu, 1.89$/bu, and...

Exploiting Soil-Management Strategies for Climate Mitigation in the European Union: Maximizing “Win–Win” Solutions across Policy Regimes Ecology and Society
Henriksen, Christian Bugge; Department of Agriculture and Ecology, Faculty of Life Sciences, University of Copenhagen; cbh@life.ku.dk; Hussey, Karen; The Fenner School of Environment and Society, The Australian National University; karen.hussey@anu.edu.au; Holm, Peter E.; Department of Basic Sciences and Environment, Faculty of Life Sciences, University of Copenhagen; peho@life.ku.dk.
The Intergovernmental Panel on Climate Change (IPCC) has identified a number of soil-management strategies that can be implemented to reduce GHG emissions. However, before deciding which of these strategies are most appropriate in any given situation, it is important to investigate how these strategies affect other aspects of sustainable development. For instance, some attempts to sequester carbon in the landscape could alter the soil’s capacity to filter water. Alternatively, other strategies could unintentionally increase net energy consumption through greater fertilizer use. Focusing specifically on opportunities to implement soil-management strategies in the European Union (EU), we discuss the synergies and trade-offs of those strategies with...

PEREIRA, N. R..
As metas de atender à crescente demanda por carne no Brasil e no exterior, aumentar a renda dos produtores da pecuária de corte e ainda reduzir as emissões de gases de efeito estufa (GEE) podem se tornar realidade por meio da intensificação tecnológica. Pesquisas identificaram os tipos de sistemas de produção mais comuns em cada bioma brasileiro, segundo diferentes níveis tecnológicos. A partir de dados primários do Censo Agropecuário 2006 do IBGE, foi feito um retrato nacional da bovinocultura de corte, o que resultou numa tipologia dos sistemas de produção praticados no País.

Assessing the environmental externalities from biofuels in Australia AgEcon
Cuevas-Cubria, Clara.
In Australia, as in other countries, the environmental costs and benefits of biofuel production and use have been found to vary greatly according to the production method and feedstocks used. In general, the use of biodiesel produced in Australia has been found to provide greater environmental benefits than ethanol, both in terms of reduced greenhouse gas (GHG) emissions and reduced air pollutant emissions. In this paper, estimates of GHG and air pollutant emissions arising from biofuels and petroleum fuels production and use are employed to calculate the change in environmental externalities when substituting biofuels for petroleum fuels in Australia. These estimates of externalities highlight the need to better understand the environmental implications...

Biofuel policies and the environment: the effects of biofuel feedstock production on climate, water quality and biodiversity AgEcon
Lankoski, Jussi E.; Ollikainen, Markku.
In this paper we examine the multiple environmental effects of policies promoting biofuel production from agricultural crops. We develop theoretical and empirical frameworks and provide an integrated economic and ecological modelling approach: an economic model of farmers’ decision making is combined with a biophysical model predicting the effects of farming practices on crop yields and multiple environmental effects. The analysed environmental effects include GHG emissions over the life cycle, nitrogen and phosphorus runoff, herbicide runoff and the quality of wildlife habitats. Model is applied to crop production in Finland. We found that the overall environmental performance of alternative land use types is mainly driven by the value of CO2-eq emissions...

Economic Impacts of GHG and Nutrient Reduction Policies in New Zealand: A Tale of Two Catchments AgEcon
Daigneault, Adam J.; Greenhalgh, Suzie; Samarasinghe, Oshadhi.
Agricultural and forestry GHG emissions are a key feature of New Zealand’s emissions profile, and New Zealand is the only country, to date, to have indicated that agricultural and forestry emissions will be covered under their domestic climate policy – the New Zealand Emissions Trading Scheme. Coupled with climate policy development is the increasing scrutiny of agricultural impacts on water. This paper uses New Zealand Forest and Agriculture Regional Model (NZ-FARM) to assess the potential economic and environmental impacts of imposing both a climate and nutrient reduction policy on the agricultural and forestry industries in the Manawatu and Hurunui/Waiau catchments in New Zealand. We find that adding a scheme that reduces catchment-level nutrients by...

Sensitivity of Carbon Emission Estimates from Indirect Land-Use Change AgEcon
Dumortier, Jerome; Hayes, Dermot J.; Carriquiry, Miguel A.; Dong, Fengxia; Du, Xiaodong; Elobeid, Amani E.; Fabiosa, Jacinto F.; Tokgoz, Simla.
We analyze the sensitivity of greenhouse gas (GHG) emissions from land-use change to modifications in assumptions concerning crop area, yield, and deforestation. For this purpose, we run a modified version of the Center for Agricultural and Rural Development (CARD) Agricultural Outlook Model, which was used previously to assess the impacts of energy price increases and biofuel policy changes on land conversion. To calculate the GHG implications of agricultural activity, we use GreenAgSiM, a model developed to evaluate emissions from land conversion and agricultural production. Both models are applied to scenarios that lead to higher US ethanol production. The results are contrasted with the findings of Searchinger et al., and we explain the role of model...

Agricultural Trade Liberalization and Greenhouse Gas Emissions: Modeling the Linkages Using a Partial Equilibrium Trade Model AgEcon
Saunders, Caroline M.; Wreford, Anita.
Global attempts to limit greenhouse gas (GHG) emissions may impact on agricultural trade and producer returns, particularly in countries such as New Zealand, where a relatively large proportion of GHG emissions originate from the agricultural sector. This study uses an extended partial equilibrium agricultural trade model to analyze the effects of trade policy liberalization on agricultural production and trade, as well as on GHG emissions. Further analysis combines trade liberalization with GHG mitigation policy in the New Zealand and European dairy sectors, and the effects on producer returns and GHG emissions are predicted. As expected, full trade liberalization in the OECD (Organization for Economic Cooperation and Development) countries enhances...

Fiddling while carbon burns: why climate policy needs emission pervasive pricing as well as technology promotion AgEcon
Pezzey, John C.V.; Jotzo, Frank; Quiggin, John C..
Effective climate policy requires global emissions of greenhouse gases to be cut substantially, which in energy sectors can be achieved by lower emissions supply technologies, greater energy use efficiency, and substitution in demand. For policy to be efficient requires fairly uniform, pervasive emission pricing from taxes, permit trading, or hybrid combinations of the two, as well as significant government support for low-emission technologies. We compare the kind of technology-focused climate policies currently adopted by Australia and the USA, the ‘'Asia-Pacific Partnership on Clean Development and Climate'’ (AP6), against this ideal policy yardstick. We find they omit the need for emission pricing to achieve abatement effectively and efficiently; they...

Greenhouse gas emissions from agriculture in the EU: A spatial assessment of sources and abatement costs AgEcon
de Cara, Stephane; Houze, Martin; Jayet, Pierre-Alain.
Agriculture contributes significantly to the emissions of greenhouse gases in the EU. By using a farm-type, linear-programming based model of the European agricultural supply, we first assess the initial levels of methane and nitrous oxide emissions at the regional level in the EU. For a range of CO2 prices, we assess the potential abatement that can be achieved through an IPCC-based emission tax in EU agriculture, as well as the resulting optimal mix of emission sources in the total abatement. Further, we show that the spatial variability of the abatement actually achieved at a given carbon price is large, indicating that abatement cost heterogeneity is a fundamental feature in the design of a mitigation policy. We assess the efficiency loss associated...

Values of Ecosystem Services Associated with Intense Dairy Farming in New Zealand AgEcon
Takatsuka, Yuki; Cullen, Ross; Wilson, Matthew; Wratten, Steve D..
The increase in greenhouse gas emissions and degradation of water quality and quantity in waterways due to dairy farming in New Zealand have become of growing concern. Compared to traditional sheep and beef cattle farming, dairy farming is more input intensive and more likely to cause such environmental damage. Our study uses choice modeling to explore New Zealanders’' willingness to pay for sustainable dairy and sheep/beef cattle farming. We investigate respondents'’ level of awareness of the environmental degradation caused by dairy farming and their willingness to make trade-offs between economic growth and improvements in the level of ecosystem services associated with pastoral farming.

Greenhouse gas emissions from livestock production AgEcon
Saunders, Caroline M.; Wreford, Anita.
Links between trade and the environment have aroused considerable interest, both in terms of the impact of trade liberalisation on the environment, and also the impact of environmental policy on production and trade. A key environmental concern is global warming. The agricultural sector both contributes to, and will be affected by, climate change. Various mitigation strategies have been proposed for agriculture, including a limit on animal numbers, and restrictions on Nitrogen fertiliser application. The effects of these mitigation options on production, trade and emissions are analysed in this paper, using a partial equilibrium, agricultural multi-country, multi-commodity trade model, extended to include production systems and GHG emissions.

Estimating and projecting flows of greenhouse gases for New Zealand agriculture and planted forests AgEcon
Austin, Darran; Rivas Palma, Rosa Maria.
New Zealand is atypical among the Annex I parties within the Kyoto Protocol with agriculture forming a large part of greenhouse gas emissions and planted forests sequestering large amounts of carbon. This presentation will summarise the methods and data used to estimate flows of greenhouse gases within agriculture and planted forests in New Zealand’s National Inventory Report submission to the United Nations Framework Convention on Climate Change last April. 2009 projections for the first commitment period of the Kyoto Protocol (2008-2012) will also be presented and discussed.

Implied Objectives of U.S. Biofuel Subsidies AgEcon
Rubin, Ofir D.; Carriquiry, Miguel A.; Hayes, Dermot J..
Biofuel subsidies in the United States have been justified on the following grounds: energy independence, a reduction in greenhouse gas emissions, improvements in rural development related to biofuel plants, and farm income support. The 2007 energy act emphasizes the first two objectives. In this study, we quantify the costs and benefits that different biofuels provide. We consider the first two objectives separately and show that each can be achieved with a lower social cost than that of the current policy. Then, we show that there is no evidence to disprove that the primary objective of biofuel policy is to support farm income. Current policy favors corn production and the construction of corn-based ethanol plants. We find that favoring corn happens to...
