Analyzing the Economic Impact of Climate Change on Global Timber Markets AgEcon
Sohngen, Brent; Sedjo, Roger A.; Mendelsohn, Robert; Lyon, Kenneth S..
In this paper, we show how ecological and economic models can be linked to determine the economic impact of climate change on global timber markets. We begin by discussing some of the important issues relevant to global impact analyses such as this. We then outline our general modeling framework and discuss the particular models that will be used. Finally, we discuss some of the important issues involved with linking the two types of models.

The Economic Value of Wetland Conservation and Creation: A Meta-Analysis AgEcon
Ghermandi, Andrea; van den Bergh, Jeroen C.J.M.; Brander, Luke M.; de Groot, Henri L.F.; Nunes, Paulo A.L.D..
The rationale for conservation and creation of wetlands stems from the recognition of both their ecological and economic values. This paper examines the welfare impacts of goods and services provided by wetlands. We collected 385 estimates of the economic value of 181 natural and man-made wetlands from 167 studies worldwide. The resulting database is less biased towards North America than previous reviews of the literature. The relative importance of characteristics of the valuation study, of the wetland site, and of the socio-economic and geographical context is estimated by means of a meta-regression analysis of wetland values. Provision of amenities, flood control and storm buffering, and water quality improvement are the most highly valued wetland...

The Rule of The Jungle in Pakistan: A Case Study on Corruption and Forest Management in Swat AgEcon
Pellegrini, Lorenzo.
Corruption in the forest sector of Swat, Pakistan is impairing the sustainable management of forest. We analyze corruption in a case study setting against the backdrop of the reform options that are most often cited as possible solutions. As we highlight in this study, the ‘crime and punishment’ approach is not feasibly implemented if the overall institutional environment is weak. Since countrywide overhaul of corruption through sweeping reform programs, the other reform approach, is a difficult and lengthy task, there is a need for an alternative kind of reform. In the case of a corruption-ridden centralised forest management regime, institutional reform should move away from enforcement of existing institutions and promote communal management of natural...

Does Targeting a Designated Area Crowd out the other Preservation Programs’ Efforts? AgEcon
Liu, Xiangping; Lynch, Lori.
Maryland has introduced a number of land preservation programs over the past 40 years to permanently preserve resource lands. Although new programs can increase the number of acres being preserved, they might have unintended impact on land preservation due to interaction with existing land preservation programs. The Maryland Rural Legacy program began in 1997 by designating large contiguous blocks of land and focusing its preservation efforts only in those areas. The program’s could attract existing programs to shift their preservation effort into this designated rural legacy areas if there exist economy of scale or they subsidized existing programs’ effort through matching funds. Alternatively, it could crowd out the others’ preservation efforts in these...

Implementation of EU Agri-Environmental Measures at the Regional Level: Economic and Political Constraints AgEcon
Bertoni, Danilo; Peri, Massimo; Olper, Alessandro.
In this paper we apply a political objective function approach developed by Salhofer and Glebe (2004) to explain the high variability of agri-environmental program implementation at the EU regional level. The analysis covers 55 EU regions during the period 2001-2002, using basic data extracted from the Common Monitoring Indicators collected by the UE Commission for the programme's evaluation process. The main results indicate that the area covered by agri-environmental programs increases in regions where budget constraints are less severe and where the social demand for environmental amenities is more relevant. Moreover, agri-environmental programs are negatively related to the participation opportunity cost and show a non linear relation with the farmer's...

Análisis econométrico de la heterogeneidad de las preferencias de los individuos: aplicación a la valoración económica de la conservación del paisaje agrícola de montaña AgEcon
Colombo, Sergio; Hanley, Nick.
The need to account for respondents’ preference heterogeneity in stated choice models has motivated researchers to apply random parameter logit and latent class models. In this paper we compare these three alternative ways of incorporating preference heterogeneity in stated choice models and evaluate how the choice of model affects welfare estimates in a given empirical application. Finally, we discuss what criteria to follow to decide which approach is most appropriate. RESUMEN: La necesidad de incorporar la heterogeneidad en las preferencias de los individuos en los modelos de elección discreta ha llevado a los investigadores a emplear siempre más frecuentemente modelos de parámetros aleatorios o de clases latentes. En este artículo se comparan tres...

Environmental Amenities and Optimal Agricultural Land Use: The Case of Israel AgEcon
Kan, Iddo; Haim, David; Rapaport-Rom, Mickey; Shechter, Mordechai.
This paper evaluates the effectiveness of changing land allocation among crops as a mechanism for increasing social welfare, where production profits and amenity benefits are augmented. A positive mathematical programming model is calibrated and applied to the northern part of Israel, using a crop-discriminating amenity-benefits function. Changes in land allocation increase social welfare by 2.4% nationwide, and by up to 15% on the regional level. Regional scale farming-profit losses amount to up to 6%. Due to the decreasing-return-to-scale nature of the amenity-benefits function, the inter-regional variability appears sensitive to the manner in which the country is divided into regions.

Brownfields Redevelopment in Wisconsin: Program, Citywide, and Site-Level Studies AgEcon
Wernstedt, Kris; Hersh, Robert.
In this paper, the second installment of our three-part study on the development of brownfields policy in the state of Wisconsin, we use case studies to explore the implementation of the policy at three scales: 1) two statewide initiatives, the Voluntary Party Liability Exemption process and the Sustainable Urban Development Zone program; 2) the efforts of two Wisconsin cities, West Allis and Wausau, to promote brownfields redevelopment across their neighborhoods; and 3) project-specific uses of institutional, regulatory, and financial innovations to encourage the revitalization of specific areas. Throughout the paper, we focus on the role of economic incentives, regulatory flexibility, regulatory structure, and the behavioral culture of brownfields...

Forecasting Irrigation Water Demand: A Case Study on the Flint River Basin in Georgia AgEcon
Banerjee, Swagata (Ban); Tareen, Irfan Y.; Gunter, Lewell F.; Bramblett, Jimmy; Wetzstein, Michael E..
Southeast drought conditions have accentuated the demand for irrigation in the face of restricted water supply. For allocating this supply, Georgia held an auction for withdrawing irrigated acreage. This auction withdrew 33,000 acres from irrigation, resulting in a physical estimate of a 399 acre-feet daily increase in water flow. The actual reduction is driven by crop distributional changes on the basis of economic substitution and expansion effects. In contrast to the physical estimates, an econometric model that considers these effects is developed. The differences between the physical and econometric models result in an increase in the estimate of water savings of around 19% to 24%.

Optimal Dynamic Management of Agricultural Land-Uses: An Application of Regime Switching AgEcon
Doole, Graeme J.; Hertzler, Greg.
The capacity of global agricultural production to meet increased demand for food from population growth and wealth accumulation is threatened by extensive land degradation. Nonetheless, previous research has focused primarily on the dynamic implications of input management and ignored land-use choice. This paper extends this theory through an examination of the intertemporal management of agricultural land through the use of non-crop inputs, such as fertilizer, and land uses that either degrade or restore productivity. The need to consider the relative total asset value of alternative crops over time is demonstrated. Moreover, higher output prices for degrading crops are shown to increase their relative value, motivating the later adoption of substitutes....

Effect of Ranchland Attributes on Recreational Hunting in Florida: A Hedonic Price Analysis AgEcon
Shrestha, Ram K.; Alavalapati, Janaki R.R..
Recreational hunting has been an attractive enterprise for some ranchers who are interested in supplementing their income from cattle. Ranchland attributes-such as parcel size, tree cover, and proximity to urban centers-are expected to influence hunters’ preferences and, thus, hunting lease payments. We estimated the effects of these attributes on hunting revenues using a hedonic model. The results reveal that trees and vegetation cover on ranchlands have a positive impact on hunting revenues, indicating opportunities for silvopasture practices. Those ranchers in Florida who maintain about 22% trees and other vegetation cover receive $16.15 acre per year from hunting leases, but doubling the cover would generate only an additional $3.20 per acre per...

Estimating Effects of an Urban Growth Boundary on Land Development AgEcon
Cho, Seong-Hoon; Chen, Zhuo; Yen, Steven T.; Eastwood, David B..
This study estimates the effects of an urban growth boundary (UGB) on land development decisions in Knox County, TN, using a heteroscedastic probit model. With combined efforts of increased land development within the city boundary and decreased development within the UGB and the neighboring town of Farragut after the implementation of UGB, the UGB of Knox County has been successful in urban revitalization within the city boundary and discouraging urban sprawl. These UGB impacts may be related to the city government having the right to annex land parcels within the UGB without consent of land owners.

Shade-Grown Coffee: Simulation and Policy Analysis for Coastal Oaxaca, Mexico AgEcon
Batz, Michael B.; Albers, Heidi J.; Avalos-Sartorio, Beatriz; Blackman, Allen.
Shade-grown coffee provides a livelihood to many farmers, protects biodiversity, and creates environmental services. Many shade-coffee farmers have abandoned production in recent years, however, in response to declines in international coffee prices. This paper builds a farmer decision model under price uncertainty and uses simulation analysis of that model to examine the likely impact of various policies on abandonment of shade-coffee plantations. Using information from coastal Oaxaca, Mexico, this paper examines the role of various constraints in abandonment decisions, reveals the importance of the timing of policies, and characterizes the current situation in the study region.

Does Information Matter? Assessing the Role of Information and Prices in the Nitrogen Fertilizer Management Decision AgEcon
Williamson, James M..
This article investigates the impact of agronomic, environmental, and price information on the management decision of nitrogen fertilizer. Because excessive nitrogen originating from agricultural production activities can cause environmental degradation, understanding how information influences the nutrient application decision on the field is important for developing strategies for nitrogen load mitigation. I investigate the value farmers place on information about N management they receive from several sources. In particular, I evaluate how farmers use information from soil N-tests to make decisions about the rate of N to apply to the field. My results show that soil N-testing can be an effective management practices for reducing excess N applications....

World Food Needs and the Optimal Allocations of Lands AgEcon
Hubert, Marie-Helene; Moreaux, Michel.
In order to assess the future world food demand/supply balance for the next century, in relation to the land uses, we develop a model in which the society has to supply two types of food demand, namely, processed crop products and meat and dairy products. From the supply side, the society can resort to different classes of land. Each class of land can be allocated wholly or partially either to crop cultivation or to pasture or last to be lain fallow. Primary crop production can be transformed either into processed crop products to satisfy final needs, or into intermediate livestock products used as inputs within the intensive industrial farming system. The livestock products can also be obtained from the extensive grazing system. The increase in world...

The Roles of Labor and Profitability in Choosing a Grazing Strategy for Beef Production in the U.S. Gulf Coast Region AgEcon
Gillespie, Jeffrey M.; Wyatt, Wayne; Venuto, Brad; Blouin, David; Boucher, Robert W..
Comparisons are made concerning labor required and profitability associated with continuous grazing at three stocking rates and rotational grazing at a high stocking rate in the U.S. Gulf Coast region. A unique data set was collected using a time and motion study method to determine labor requirements. Profits are lowest for low stocking rate– continuous grazing and high stocking rate–rotational grazing. Total labor and labor in three specific categories are greater on per acre and/or per cow bases with rotational-grazing than with continuous-grazing strategies. These results help to explain relatively low adoption rates of rotational grazing in the region.

Adoption of Soil Erosion Control Practices in Southern Spain Olive Groves AgEcon
Franco, Juan Agustin; Calatrava-Leyva, Javier.
This paper presents results from a survey carried out in 2005 among 147 olive tree farmers from the Alto Genil River Basin in Southern Spain regarding the adoption of soil conservation and management practices. Olive tree groves in South-eastern Spain's mountainous areas are subject to a high risk of soil erosion and have to incur in high costs of soil conservation. This results in great difficulties to comply with cross-compliance and to benefit from agri-environmental schemes. Our main objectives are to analyse the current level of adoption of soil conservation practices and to analyse which socio-economic and institutional factors determine such adoption. Three Probit models are estimated. Dependant variables are three different soil conservation...
