Can a Warmer Climate Save Northern Agriculture? AgEcon
Gaasland, Ivar.
Agriculture at high latitudes is expected to be a main beneficiary of a man-made climate change. A numerical model, using Norway as a case, is employed to analyze the impacts of a warmer climate on northern agriculture. The computations indicate that the current degree of self-sufficiency can be achieved with less budget support and higher economic welfare. However, it may be argued that environmental goods, such as landscape and biodiversity preservation, and rural settlement, are more important than self-sufficiency for northern agriculture. It is demonstrated that, in that case, welfare gains are substantially lower, and can even be negative.

Land Degradation in Ethiopia: What Do Stoves Have To Do With It? AgEcon
Gebreegziabher, Zenebe; van Kooten, G. Cornelis; van Soest, Daan P..
In Ethiopia deforestation is a major problem and many peasants have switched from fuelwood to dung for cooking and heating purposes, thereby damaging the agricultural productivity of cropland. The Ethiopian government has embarked on a two-pronged policy in an effort to stem deforestation and the degradation of agricultural lands: (i) tree planting or afforestation; (ii) dissemination of more efficient stove technologies. The motivation in here is, therefore, to examine the potential of the strategy of disseminating improved stoves in the rehabilitation of agricultural and forests lands. For empirical analysis we used a dataset on cross-section of 200 farm households from the highlands of Tigrai, northern Ethiopia. We used a two-step procedure reminiscent...

Effects of Forestland Ownership Conversion on Greenhouse Gas Emissions: The Case of South Korea AgEcon
Cho, Seong-Hoon; Kim, Hee Ho; Roberts, Roland K.; Kim, Seung Gyu; Lee, Daegoon.
This research analyzed the effects of forestland conversion from private to public ownership on greenhouse gas emissions by quantifying the relationship between forestland ownership conversion and deforestation, and then examining the effects of the change in deforestation on greenhouse gas emissions in South Korea. Ex ante simulations forecast greenhouse gas emissions resulting from deforestation rates under the current level of national forestland and three scenarios of increased percentages of national forestland. The findings suggest that increasing the percentage of national forestland would mitigate the increase in the deforestation rate, which in turn would moderate the increase in greenhouse gas emissions.

Plant Species Protection Contracts: Modelling Contract Choice for Specialised Dairy Farms and Mixed Dairy Pig Fattening Farms in the Netherlands AgEcon
Peerlings, Jack H.M.; Polman, Nico B.P..
Proposals of the European Commission stress the future importance of agri-environmental payments within the rural development policy of the European Union. The aim of this paper is to present and discuss a model for choice for plant species protection contracts in the Netherlands. The model includes transaction costs, time and the possibility of lock-in situations related to contract choice. The approach discussed is flexible because it makes it possible to introduce all kinds of technical and institutional restrictions (differences in contract design).

Modelling Land Use in Rural New Zealand AgEcon
Olssen, Alex; Kerr, Suzi.
Regional Councils are primarily responsible for environmental management, as specified in the Resource Management Act (RMA), 1991. The Local Government Act 2002 has an integrative component, requiring consideration of social, economic, environmental and cultural well-being of their communities. These two Acts are interesting, as their combination is shaping new governance structures within New Zealand. Different types of policy instruments are available to Regional Councils while carrying out their functions: regulatory, economic and voluntary. The 1990s are characterized by ‘first generation Plans’ of the RMA, which were highly rule focused. In the 2000s a marked shift occurred, mainstreaming ‘community’ and participative approaches to policy. This...

Crop biodiversity repercussions of subsidized organic farming in Greece AgEcon
Nastis, Stefanos A.; Michailidis, Anastasios; Mattas, Konstadinos.
This paper analyzes the impact of CAP financial assistance on crop biodiversity under uncertainty. A stochastic production function is employed and estimated to assess whether risk-averse farmers hedge risk by diversifying their portfolio of crops, thus increasing crop biodiversity. The model is applied to farm-level data of organic crop farms in Greece. Organic farming financial assistance poses a double-edged sword: even though it is considered agrobiodiversity enhancing as a cultivation method, subsidizing it can become agrobiodiversity reducing, since farmers may select to cultivate only the subsidized crops. The study shows that risk aversion leads to crop biodiversity conservation. However, providing CAP financial assistance on certain crops appears...

Land-use Change and Solar Energy Production: A Real Option Approach AgEcon
Ardjan, Gazheli; Di Corato, Luca.
In this paper a real option model is developed to examine the critical factors affecting the decision to lease agricultural land to a company installing a PV power plant. The leasing payment is certain while the net revenues from agriculture are uncertain. We identify the profit values at which the farmer decides to lease his plot vs. continue farming it. By applying the model to the province of Bologna (Italy), we illustrate the possible land-use change scenarios in this area. We conclude by discussing the importance of PV energy production as a source of income for farmers and its implications from a social perspective.

Expanding the National Flood Insurance Program to Cover Coastal Erosion Damage AgEcon
Keeler, Andrew G.; Kriesel, Warren; Landry, Craig E..
This paper uses the results of a nationwide survey of coastal property owners to estimate the demand for insurance against erosion damage. The National Flood Insurance Program (NFIP) does not technically cover such damage, although in practice there is considerable uncertainty about this point. The ability to insure against such losses has implications for the choice of beach management strategies and for NFIP management. We find significant demand for insurance at prices in the range of current flood insurance premiums, although median willingness to pay appears to be less than cost of providing such insurance.

Precio de la tierra con presión urbana: un modelo para España AgEcon
Decimavilla, Esther; San Juan, Carlos; Sperlich, Stefan.
RESUMEN: Estudiamos el precio de la tierra para uso agrario y las variables que determinan su evolución en España, tratando de identificar qué parte de la subida de precios observada se justifica por elementos «internos», relacionados con la renta agraria esperada, y cuál proviene de elementos externos o especulativos, vinculados a cambios en el uso del suelo. Además se relaciona el ciclo de precios con la aceleración de la especialización en el ámbito regional y la integración en la PAC. La novedad de este trabajo consiste en identificar, mediante técnicas de datos de panel, factores no fundamentales (presión urbanizadora, creación de regadíos, cambio demográfico) que, además de los fundamentales (ingresos esperados y localización geográfica) determinan...

Does tendering conservation contracts with performance payments generate additional benefits? AgEcon
Schilizzi, Steven; Breustedt, Gunnar; Latacz-Lohmann, Uwe.
Policy makers aiming to get private landholders to supply non-marketed environmental services may need to provide efficient economic incentives. Two ideas have been explored to achieve this: linking contract payments to environmental outcomes and submitting the contracts to competitive tender. This paper investigates whether there are any gains to be had by combining the potential benefits of both approaches. Landholders’ risk aversion to only partially controlled outcomes may offset incentive effects if the fall in participation outweighs any increases in individual effort. Controlled lab experiments were designed on the basis of a theoretical model and were run in two countries, with varying rates of payments linked to environmental outcomes. Results...

Landlord Satisfaction with Arkansas Agricultural Land Agreements AgEcon
Rainey, Ronald L.; Dixon, Bruce L.; Parsch, Lucas D.; Ahrendsen, Bruce L.; Bierlen, Ralph W..
Landlord satisfaction levels with agricultural land-leasing agreements are examined with a 1998 sample of Arkansas landowners. Ordered probit models are estimated identifying which factors significantly affect satisfaction levels. Results indicate that the type of lease is not a significant determinant of landlord satisfaction levels. Proportion of landlord’s income from leasing, tenant educational background, social capital variables, presence of irrigation equipment, and perceptions about the FAIR Act were found to significantly affect lease satisfaction in at least one of the three satisfaction models estimated. A comparison with an earlier study of Arkansas tenants indicates landlords have generally higher satisfaction levels.

A Binary Logit Estimation of Factors Affecting Adoption of GPS Guidance Systems by Cotton Producers AgEcon
Banerjee, Swagata (Ban); Martin, Steven W.; Roberts, Roland K.; Larkin, Sherry L.; Larson, James A.; Paxton, Kenneth W.; English, Burton C.; Marra, Michele C.; Reeves, Jeanne M..
Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems.

CLIMATE CHANGE MITIGATION AND FUTURE FOOD CONSUMPTION PATTERNS AgEcon
Valin, Hugo; Havlik, Petr; Mosnier, Aline; Obersteiner, Michael.
Discussions on climate change increasingly emphasize the contribution of agricultural activities to anthropogenic greenhouse gases emissions. In this paper, we investigate from a supply to demand side perspective the stress between food demand and climate change challenges up until 2030. We examine how more stringent climate change mitigation policies could alter agricultural markets and put at risk the nutrition possibilities of populations. We use for this purpose GLOBIOM, an applied partial equilibrium model covering, at the world scale and a fine grid resolution, the main land-based sectors: agriculture, forestry and bioenergy. For this exercise, the model is fully linked to a semi-flexible endogenous demand system with non-linear Engel’s curves. Our...

Prospects for climate friendly peatland management – Results of a socioeconomic case study in Germany AgEcon
Schaller, Lena; Kantelhardt, Jochen.
In the current debate on climate protection, agricultural production has become a focal point of interest. This study introduces the climate effectiveness of agricultural management of peat-soils. Agriculture on peatland demands a water-level drawdown that causes aerobe degradation of the soils. The resulting trace-gas emissions have a negative impact on the greenhouse-gas balance. In Germany more than 80% of peatland is used agriculturally; the resulting emissions account for 2.3 – 4.5% of Germany’s overall emission. Climate-friendly peatland management strategies, however, demand enhanced groundwater tables and decreased land-use intensity. With regard to agricultural income, severe economic consequences are to be expected. Against this background we...

Combining mixed logit models and random effects models to identify the determinants of willingness to pay for rural landscape improvements AgEcon
Campbell, Danny.
This paper reports the findings from a discrete choice experiment study designed to estimate the economic benefits associated with rural landscape improvements in Ireland. Using a mixed logit model, the panel nature of the dataset is exploited to retrieve willingness to pay values for every individual in the sample. This departs from customary approaches in which the willingness to pay estimates are normally expressed as measures of central tendency of an a priori distribution. In a different vein from analysis conducted in previous discrete choice experiment studies, this paper uses random effects models for panel data to identify the determinants of the individual-specific willingness to pay estimates. In comparison with the standard methods used to...

The Supply of Private Acreage for Public Recreational Use in Southern and Central Appalachia AgEcon
Liu, Zheng; Pagoulatos, Angelos; Hu, Wuyang; Fleming, Ronald A..
Public lands in Southern and Central Appalachia (SCA) available for outdoor recreational pursuits are limited relative to the rest of the county. This study identifies factors that encourage private land owners to permit public access to their land for recreational purposes and determines how much acreage would be offered in the Southern and Central Appalachia region. The Tobit and Heckman’s sample selection models suggest that the probability of offering land to the public is correlated with the number of acres offered. Having acreage suited for recreation is a positive determinant of acres leased but attributes developed by the landowner act as a disincentive. Type of recreational activity has no effect on the landowner’s decision and the supply of...

Spatial Externalities and Vector-Borne Plant Diseases: Pierce’s Disease and the Blue-Green Sharpshooter in the Napa Valley AgEcon
Fuller, Kate B.; Alston, Julian M.; Sanchirico, James N..
Pierce’s Disease (PD) is a bacterial disease that can kill grapevines over a span of one to three years. In this paper, we examine and model PD and vector control decisions made at the vineyard level in the Napa Valley in an effort to understand how the pest and disease affect individual growers, and to examine spatial externality issues and potential benefits from cooperation between adjacent vineyards. The model that we created adds to the literature by (a) treating grape vines as capital stocks that take time to reach bearing age and thus cannot be immediately replaced in the event of becoming diseased. We also (b) relax the assumption of an interior solution by examining the boundaries of parameter space for which winegrape growing is profitable and...
