A state-level analysis of the Re-enrollment and Extension (REX) program on southern states indicates a positive relationship between percentage of tree acreage and Conservation Reserve Program (CRP) re-enrollment for states in which conservation acreage is dominated by trees. However, the relationship depends on crop mix where CRP acreage is dominated by grass. County-level analysis suggests that states will differ in how quickly they opt out of CRP. Of the states examined, Arkansas is the most likely to move land to corn, with Mississippi the least likely. Arkansas and Kentucky will switch to soybean first, followed by Mississippi and Georgia.

This study presents a thorough discussion of the efficiency and effectiveness improvement from optimization models (Binary Linear Programming and Goal Programming), as applied to the Department of Defense’s Readiness and Environmental Protection Initiative. The OM models can yield 21% and 19.1% higher benefit scores respectively, spending $13,013,473 and $31,463,473 less total acquisition costs. To achieve the same level of conservation benefits for the current rank based approach, the REPI would spend additional $20.1 million and approximate 50% of the budget. A counterpart of OM- the cost-effective analysis is observed to be inefficient when the problem becomes complex. In a real world of political environment of the conservation programs, we suggest a...

This paper uses an economic catchment model to assess changes in land use, enterprise distribution, greenhouse gas emissions and nutrient loading levels from a series of policies that introduce carbon prices or nutrient reduction caps on land-based production in the Hurunui Catchment in Canterbury, New Zealand. At $20/tCO2e, net revenue for the catchment is reduced by 7% from baseline levels while GHGs are reduced by 3%. At $40/ tCO2e, net revenue is reduced by 15% while GHGs are reduced by 21%. Nitrogen and phosphorous loading levels within the catchment were also reduced when landowners face a carbon price, thus providing other benefits to the environment. Additional scenarios in this paper assess the impacts from developing a large-scale irrigation...

The Conservation Reserve Program (CRP) is the largest land retirement program ever operated in the US. Since its inception in 1985, many researchers have studied the impacts of this program; however, only a few have analyzed how the CRP affects surrounding non–enrolled parcels. In this research I examine how the CRP may affect the conversion of non–cropped land to agriculture, a phenomenon referred to as “slippage” in the literature, and specifically addressed by Wu (2000) and Roberts and Bucholtz (2005). Building on these earlier studies, I empirically model slippage using data derived from satellite imagery that provides information on land cover changes between 1992 and 2001. The study area consists of 1,053 counties located in the Northern Plains, Corn...

Shrimp farming in Thailand has had disastrous effects on the environment in the past, which has prompted a government ban on shrimp production in inland areas. However, a new low-salinity shrimp farming system has developed that seems to have fewer disease and environmental problems than previous systems but competes with rice production for land and water resources. The present study found that shrimp farming exhibits increasing returns to scale and is much more profitable than rice farming, which offers opportunities for rice farmers to improve their incomes through diversification. No evidence was found for external environmental effects of shrimp production on rice production or vice versa. A total ban on shrimp production in rice farming areas...

Socio-economic Scenarios of Agricultural Land Use Change in Central and Eastern European Countries

Fekete-Farkas, Maria; Rounsevell, Mark; Audsley, Eric.

The study presented in this paper is part of the ACCELERATES (Assessing Climate Change Effects on Land Use and Ecosystems from Regional Analysis to The European Scale) project whose main goal is the construction of integrated predictions of future land use in Europe. The scenarios constructed in the project include estimates not only due to changes in the climate baseline, but also estimates due to possible future changes in socio-economics. The overall aim of the ACCELERATES was to assess the vulnerability of European agroecosystems based on economic and environmental considerations in term of both their sensitivity and capacity to adapt changes. The historical background, the type of economy, the policy aim and governance and importance of agriculture in...

This paper analyzes carbon leakage due to reduced emissions from deforestation (RED). We find that leakage with RED is good because the policy induces afforestation that contributes to a further carbon sequestration. By ignoring the domestic component of carbon leakage, the literature can either overestimate or underestimate leakage, depending on the magnitudes of the numerator and the denominator of the leakage formulas. Unlike the literature, we include the land and agricultural markets in the analysis of carbon leakage with forestation policies. In this model, carbon leakage depends on: (1) supply and demand elasticities of timber production and consumption, respectively in the country introducing a RED policy (Home country) and in the rest of the...

Supporters of the effort to link cleanups at hazardous waste sites to the sites' expected land uses claim that amending language in the federal Superfund statute to allow this may yield a number of benefits. These include rationalizing the cleanup process and decreasing cleanup costs, promoting economic development in the local communities that host Superfund sites, and helping such communities exercise more control over the cleanups. However, interviews with Superfund stakeholders and a detailed case study call into question these arguments. The current role of land use in cleanup, uncertainties about whether economic development is likely at the bulk of Superfund sites, the long-run viability of institutional controls, the willingness of communities to...

The U.S. Geological Survey has determined that irrigation in Arkansas’ Delta is unsustainable. This study examines how irrigation restrictions would affect county net returns to crop production. It also considers the effect of planting less water-intensive bioenergy crops—switchgrass and forage sorghum—in the event biofuel markets become a reality. Results suggest that sustainable irrigation restrictions without bioenergy crops would decrease producer returns by 28% in the region. Introducing these alternative crops would both reduce groundwater use and may restore state producer returns, albeit with significant spatial income redistribution to crop production throughout the state.

Brownfields Redevelopment in Wisconsin: A Survey of the Field

Wernstedt, Kris; Crooks, Lisa; Hersh, Robert.

As the third paper in our three-part series on Wisconsin brownfields, this paper reports the results of a survey on the objectives of brownfields redevelopment, constraints to the redevelopment, the role of the state's Department of Natural Resources (DNR), and institutional controls. The 260 survey respondents include elected officials, staff from economic development and planning agencies, attorneys, private sector representatives, and professionals at nonprofit organizations. We find that: 1) respondents value both economic and environmental gains associated with brownfields redevelopment; 2) the high costs of cleanup are the principal barrier to brownfields redevelopment; 3) no single factor stands out as constraining DNR's ability to oversee cleanups;...

About 30 percent of the world’s soil carbon is stored in peat soils. Peatland’s functional principle of carbon storage greatly depends on management strategies. Therefore agricultural peatland use becomes a focal point of interest in the current debate on climate protection. Agricultural management demands a drawdown of the water-level that causes aerobe degradation of the soils, as well as trace-gas emissions which have a negative impact on greenhouse-gas balance. Climate-friendly peatland management strategies, however, demand enhanced groundwater tables and decreased land-use intensity. Against this background we analyse ways of re-organising agricultural peatland use within a case study located in Germany, where intensive peatland use accounts for 2.3...

Zoning decisions related to residential lot size and density affect residential land value. Effects of size on residential parcel value in Roanoke County, VA, are estimated with fixed effects hedonic models. Parcel size; elevation; soil permeability; proximity to urban areas, malls, and roads; and location influence parcel value, but the effects vary by value of construction and development status. Parcel value per square meter declines with increasing parcel size. The estimated relationships could be used to evaluate zoning decisions in terms of land values and tax revenues if model estimation uncertainties and responses by developers to zoning strategies are considered.

The Impact of Agriculture on Waterfowl Abundance: Evidence from Panel Data

Wong, Linda; van Kooten, G. Cornelis; Clarke, Judith A..

Agricultural expansion and intensification in Canada’s Prairie Pothole Region (PPR) have contributed to declining waterfowl populations since the 1970s. Although this region represents a mere 10% of North America’s waterfowl breeding habitat, it produces over 50% of the continent’s duck population and roughly 60% of Canada’s agricultural output. Thus, intense competition exists between private economic interests and public benefits in the PPR. To better understand the conflict between agricultural and wildlife uses of land, panel methods are used to examine the spatiotemporal variation of waterfowl populations and agricultural land use intensity in the PPR from 1961-2006. For the main static model, we find that a one percent increase in cropland or pasture...

Buying environmental services from private landholders using tendering mechanisms are usually subject to a budget constraint. Auction theory has mostly focused on target-constrained auctions and is less well developed for this type of auction. This paper examines a theoretical model specifically developed for budget-constrained tenders and assesses its capacity to predict tendering performance under information limitations typical of those found in field applications. But this assessment cannot be done without complementing the model with controlled laboratory experiments. Subject to their external validity, we find that the model is able to make the correct policy recommendation when comparing the tender to an equivalent fixed price scheme, even when the...

Recent extreme weather events have resulted in an ongoing discussion on the issues of land use and compensation payments within Austrian agriculture. Building on a functional evaluation system for agricultural lands as developed within the Interreg IIIB project “ILUP”, the national project “Agriculture and Flooding” has as its goal to classify the flood-protection contribution and flood sensitivity of agricultural lands. This, in turn, enables the recommendation of targeted measures for potentially improving flood situations, as well as an estimate of their implementation costs. In addition to the digital soil map, other fundamental sources used for the project are the digital flood risk map, IACS land-use data and works by the Institute for Land and Water...

The non-permanence of optimal soil carbon sequestration

Hediger, Werner.

Carbon sequestration in agricultural soils is considered as an option of greenhouse gas mitigation in many countries. But, the economic potential is limited by the dynamic process of saturation and the opportunity cost of land use change. In addition, this article shows that permanence cannot, in general, be achieved in the strict sense of maintaining the soil carbon stock on an increased equilibrium level. Rather, a cyclical pattern with periodical release of sequestered carbon can be economically optimal from both the farmers’ and societal point of view.

There have long been concerns that federal crop insurance subsidies may significantly impact land use decisions. It is well known that classical insurance market information asymmetry problems can lead to a social excess of risky land entering crop production. Our conceptual model shows that the problem will arise absent any information failures. This is because the subsidy is i) proportional to acres planted, and ii) greatest for the most production risky land. Using farm-level data, we follow this observation through to establish the implications of subsidies for the extent of crop production, with particular emphasis on U.S. regions where the cropland growth is likely to have marked adverse environmental impacts. Simulation results show that when...

The use of mathematical models to describe the interactions of variables is useful in modern management. In this paper, a 'mixed' model combining the knapsack problem, a household model and a form of spatial equilibrium model into a modelling framework is developed. The impacts of changes in off-farm wage rates, transaction costs in the rental market, the output prices of paddy crops, and land transactions were examined in the model. The simulation has led to the conclusion that the real benefits to farm households from land consolidation may not be apparent until the real opportunity cost of farm labour begins to rise. In addition, a reform policy in the administrative sector which encourages, not only the process of land accumulation and the rental...
