This research examines effects of various factors on farmer participation in agricultural tree plantations for economic, environmental, social and carbon-uptake purposes. Using data from a survey of Canadian agricultural landowners, a discrete choice random utility model is used to determine the probability of farmers' participation and corresponding mean willingness to accept (WTA) compensation for a tree-planting program. WTA includes positive and negative nonmarket benefits to landowners from planting trees. Estimates of WTA are less than foregone agricultural rents, but average costs of creating carbon credits still exceed their projected value under a CO2-emissions trading scheme

A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

Coping with Natural and Institutional Drought

Schuck, Eric C.; Frasier, W. Marshall.

Groundwater and surface water in the South Platte River basin of northeastern Colorado are hydraulically linked. Consequently, use of groundwater in the basin reduces surface water flows in the South Platte River. To avoid open-access problems in this situation, both surface water and groundwater in the basin are jointly administered under the prior appropriation doctrine. This gives preference to the earliest developed water rights relative to later rights when water supplies are insufficient to meet all demands. Groundwater development typically occurred after surface water development, so rights related to groundwater are generally sufficiently junior as to be exercised only in the wettest years. Historically, the state engineer has been empowered to...

The economics of transmission constraints on wind farms: some evidence from South Australia

Boerema, Nicholas; MacGill, Iain.

The impacts of transmission congestion and network investment on the development of the Australian wind energy industry have received growing attention from wind farm developers as well as relevant policy stakeholders such as the Australian Energy Market Commission (AEMC). There are many potential wind farm sites across the country with excellent wind regimes yet only limited transmission capacity. At least one wind farm in South Australia has spent a period following construction where its output was curtailed by transmission constraints (NEMMCO, 2009). Current market rules do not guarantee dispatch to an existing wind farm as more wind generation connects to the same transmission. Given the expense of transmission network extension and augmentation,...

Factors Influencing Consumer Likelihood of Purchasing a Flexible-Fuel or Hybrid Automobile

Li, Xiaogu; Clark, Christopher D.; Jensen, Kimberly L.; English, Burton C.; Yen, Steven T..

Developing fuels and vehicles that reduce our reliance on fossil fuels has become a priority due to the threat of global climate change and desire for reduced dependence on oil imports. Flexible-fuel vehicles that can run on ethanol/gasoline blends of up to 85% ethanol and hybrid electric vehicles present two such opportunities. While production of both flexible-fuel and hybrid vehicles is increasing, there is still a great deal of uncertainty about how consumers will respond to these products. To address this uncertainty, data was collected through an online survey of automobile owners that asked respondents how likely they were to choose either a flexible-fuel or hybrid vehicle as their next vehicle. A bivariate probit model was used to jointly analyze...

Tropical forests are biodiversity-rich but are dwindling at a rapid rate, not only in Southeast Asia but elsewhere also. The result is a loss of natural ecosystems, a reduction in carbon sequestration, and increasing global extinction of wild species, including iconic species. While several developments contribute to the destruction of tropical forests, the main threat comes from their clearing for the purpose of agricultural production, for example in the Amazon Basin for the expansion of the beef industry and soya bean cultivation. In Borneo and Sumatra, the principal threat to tropical forests comes from the expansion of oil palm (Elaeis guineensis) cultivation. This is expected to result in significant biodiversity loss and is a danger to the...

The threat of global warming calls for a major transformation of the energy system the coming century. Modeling technological change is an important factor in energy systems modeling. Technological change may be treated as induced by climate policy or as exogenous. We investigate the importance of induced technological change (ITC) in GET-LFL, an iterative optimization model with limited foresight that includes learning-by-doing. Scenarios for stabilization of atmospheric CO2 concentrations at 400, 450, 500 and 550 ppm are studied. We find that the introduction of ITC reduces the total net present value of the abatement cost over this century by 3-9% compared to a case where technological learning is exogenous. Technology specific polices which force the...

Environmental Targets and Shadow Prices of Bad Outputs in Organic and Conventional Farming

Huhtala, Anni; Marklund, Per-Olov.

We present a framework for deriving shadow prices for negative environmental impacts regulated in agriculture. The shadow prices can be used as indicators of the costs of environmental regulation imposed as reflected in alternative farming technologies adopted. We illustrate our analytical findings with implications of the Finnish water protection policy measures on conventional and organic livestock farms over the period 1994-2002. Generally, the representative organic farm is found to be more technically efficient relative to its own technology than is the conventional representative farm. However, there is no statistical indication of a difference between these two particular representative farms in valuing the costs of undesirable output (manure) at...

This paper generalizes the Grossman-Helpman political economy model to characterize the structure of environmental and industry protection for a small open economy when domestic and/or trade policies are the outcome of a noncooperative common agency game between sector-specific producer lobbies and the government. For a consumption externality, the political equilibrium results if domestic and trade policies are available, are production-enhancing protection of organized industries, but the same environmental protection as Pigouvian taxes. Subsidies to organized industries counterbalance environmental taxes when there is a production externality, and it is ambiguous whether domestic or trade policy alone leads to more environmental protection. In addition,...

Assuming a competitive market, conditions are determined for when a steady-state equilibrium does not exist in the optimal dynamic management of a biological population. Irregular and unpredictable behavior (called "chaos") can arise from fully rational economic decision making. High interest rate, adjustment costs, and an inelastic demand can contribute to market instability.

It is well known from the compliance literature that whenever it costly to monitor agents' compliance to contract terms, compliance is likely to be incomplete. This paper goes one step further by examining the implications of incomplete monitoring on agent's sales offers in auctions for environmental contracts. From a monitoring perspective we show allocation contracts to least cost also produces another gain – that less resources need to be spend on monitoring and enforcement. To get full use of this insight one needs to have auction procedures that provide incentives for truthful revelation of agents' private alternate incomes. Our second result is that the incentives for truthful revelation is lost when monitoring is incomplete unless the expected value...

Agribusiness, farm business and agricultural-environmental decisions which varied in their characteristics were used to evaluate multiple criteria decision making (MCDM) in an agricultural context. This paper discusses differences between the case studies, strengths and weaknesses of the methods used, and the success of the MCDM process based on participants’ expectations and experiences. While MCDM can help identify the best decision, the main benefits identified in using MCDM included better understanding of their own and other’s perspectives, a means to explain the decision and a structured way to work through the decision process. Key problem areas identified included time limitations, understanding and ownership.

Surface water pollution caused a growing concern for environmental damages (algine bloom, waterlife reduction, etc.) mostly for some aspects connected to public health (through the food chain or directly to water management), to crops and to soils (loss of fertility and foodstuff production capacity) especially given by the accumulation of toxic substances. In 1991 the Veneto Region Land Reclamation Union began to cooperate with ESAV in order to carry out an investigation on water quality conditions to optimize its use and to prevent pollution. The results emerging from this enquiry are taken into consideration in this study-case, as regards the main soluble nitrogen (nitrates) and phosphorus (ortophosphates) forms to know the level of nitrogen and...

The objective of this study is to estimate the impact of natural amenity on farmland values in the contiguous United States using a quantile regression approach and data from the 2006, 2007, and 2008 Agricultural Resource Management Surveys. The contribution of this study is three-fold. First, we explicitly include variables representing natural amenity and soil characteristics of farmland. Second, we employ a quantile regression approach to examine potentially heterogeneous impacts of natural amenity and soil characteristics at different quantiles of farmland values. Third, we utilized data from a nationwide survey of farm household to examine findings in studies using regional data are consistent at a national scale. Our quantile regression analysis...

Shocks, Sensitivity and Resilience: Tracking the Economic Impacts of Environmental Disaster on Assets in Ethiopia and Honduras

Carter, Michael R.; Little, Peter D.; Mogues, Tewodaj; Negatu, Workneh.

Droughts, hurricanes and other environmental shocks punctuate the lives of poor and vulnerable populations in many parts of the world. The direct impacts can be horrific, but what are the longer-term effects of such shocks on households and their livelihoods? Under what circumstances, and for what types of households, will shocks push households into poverty traps from which recovery is not possible? In an effort to answer these questions, this paper analyzes the asset dynamics of Ethiopian and Honduran households in the wake of severe environmental shocks. While the patterns are different across countries, both reveal worlds in which the poorest households struggle most with shocks, adopting coping strategies which are costly in terms of both short term...

The impact of nature conservation on agricultural greenhouse-gas (GHG) emissions – an economic assessment of selected German study regions

Schaller, Lena; Droesler, Matthias; Kantelhardt, Jochen.

Using a significant amount of public funding, large-scale nature-conservation projects in Germany aim to secure and develop ecologically valuable areas and endangered habitats and species. Due to the substantial land-use changes accompanying these projects, their implementation can also have relevant climate effects – one result which has not been explicitly focused upon previously. Our study analyses major cost positions in implementing such projects, particularly the expense of changing or abandoning agricultural land-use for conservation purposes. We link public funding to relevant climate effects and derive CO2 abatement costs. Therefore we conduct plot-specific ex-post analyses of agricultural land-use and greenhouse-gas (GHG) emissions. Our study...

As the United States begins to move towards putting an economic value on reducing greenhouse gas (GHG) emissions, the need for improved accounting standards becomes acute. Lifecycle analysis (LCA), which involves the systematic collection and interpretation of material flow in all relevant processes of a product, has become the accepted procedure to use to determine greenhouse gas emissions of products ranging from transportation fuels, to building materials, to food production (Farrell et al., 2006; Hill et al., 2006; Owen, 2004). The basic motivation of LCA is that, to conduct a fair assessment of the environmental impacts of a product, it is necessary to take into account all of the processes throughout the product’s lifespan, including the extraction...
