Analysis of Property Values, Local Government Finances and Reservation of Land for National Parks and Similar Purposes AgEcon
Tisdell, Clement A.; Pearson, Leonie J..
The impact on local government finances of the reservation of land for national parks in local government areas has been a bone of contention. This article analyses the situation. It identifies conditions in which the reservation of land for national parks increases total rateable unimproved property values in a local government area. The level of a local government’s receipts from rates tend to move in the same direction as the total value of rateable property in its local government area. Thus, even though national parks and similar natural areas are not rateable, it is possible that the reservation of some local government areas for such protection, can increase the receipts from rates of the local council concerned. However this is not always so and...

Characterizing Spatial Pattern in Ecosystem Service Values when Distance Decay Doesn’t Apply: Choice Experiments and Local Indicators of Spatial Association AgEcon
Johnston, Robert J.; Ramachandran, Mahesh; Schultz, Eric T.; Segerson, Kathleen; Besedin, Elena Y..
Stated preference analyses commonly impose strong and unrealistic assumptions in response to spatial welfare heterogeneity. These include spatial homogeneity or continuous distance decay. Despite their ubiquity in the valuation literature, global assumptions such as these have been increasingly abandoned by non-economics disciplines in favor of approaches that allow for spatial patchiness. This paper develops parallel methods to evaluate local patchiness and hot spots in stated preference welfare estimates, characterizing relevant patterns overlooked by traditional approaches. The analysis draws from a choice experiment addressing river restoration. Results demonstrate shortcomings in standard treatments of spatial heterogeneity and insights available...

Az erdők éve 2011! – Nemzetközi összefogás az erdőkért AgEcon
Solymos, Rezso.
„Kísértet járja be Európát és Észak-Amerikát: az erdőpusztulás kísértete.” Ezzel a drámai hangvételű mondattal kezdődik a World Resources 1986. évi kötetének erdőkkel foglalkozó része, ami a 70-es években kezdődött nagyarányú erdőpusztulás világméretű „jajkiáltása” volt, melynek visszhangja: „Mentsétek meg a Föld erdeit – amíg nem késő, amíg van mit megmenteni és megőrizni!” Nemzetközi tudományos, világméretű társadalmi fórumok témájává vált az erdő. Az emberiség egyre jobban ráébredt arra, hogy az erdő az emberiség létfeltételeinek elengedhetetlen része. Ebben nagy jelentősége volt a Római Club állásfoglalásának a növekedés határairól. A Stockholmban rendezett első környezetvédelmi világértekezlet, majd a Brundtland Bizottság közös jövőnkről készített...

Information, Stability and Dynamics in Networks under Institutional Constraints AgEcon
Olaizola, Norma; Valenciano, Federico.
In this paper we study the effects of institutional constraints on stability, efficiency and network formation. More precisely, an exogenous "societal cover" consisting of a collection of possibly overlapping subsets that covers the whole set of players and such that no set in this collection is contained in another specifies the social organization in different groups or "societies". It is assumed that a player may initiate links only with players that belong to at least one society that s/he also belongs to, thus restricting the feasible strategies and networks. In this way only the players in the possibly empty "societal core", i.e., those that belong to all societies, may initiate links with all individuals. In this setting the part of the current...

ENVIRONMENTAL JUSTICE: AVOIDING THE DIFFICULTY OF PROVING DISCRIMINATORY INTENT IN HAZARDOUS WASTE SITING DECISIONS AgEcon
Kiniyalocts, Melissa.
Contrary to general public perception that environmental hazards are borne equally, the risks and accompanying burdens of exposure to environmental contaminants are distributed disproportionately along racial and class lines. The environmental justice movement has received much recent attention as being an extension of the civil rights movement, where advocates have demanded fair distribution of environmental benefits and burdens. This paper focuses on the difficulty that plaintiffs wishing to challenge hazardous waste siting in their communities have in proving that the siting decision was based on racial factors. Part 1 examines a North Carolina case that illustrates the potential that substantive and procedural requirements have in protecting...

Acceptable Reforms of Agri-Environmental Policies AgEcon
Bontems, Philippe; Rotillon, Gilles; Turpin, Nadine.
We consider a model of regulation for nonpoint source water pollution through non linear taxation/subsidization of agricultural production. Farmers are heterogenous along two dimensions, their ability to transform inputs into final production and the available area they possess. Asymmetric information and participation of farmers to the regulation scheme put constraints on the optimal policy that we characterize. We show that a positive relationship between size of land and ability may exacerbate adverse selection effects. We then introduce acceptability constraints and show that the intervention under acceptability amounts to reallocate production towards inefficient farmers who benefit from the reform at the expense of efficient producers. Last, we...

VALUING WATER QUALITY MONITORING: A CONTINGENT VALUATION EXPERIMENT INVOLVING HYPOTHETICAL AND REAL PAYMENTS AgEcon
Spencer, Michael A.; Swallow, Stephen K.; Miller, Christopher J..
This paper studies the preferences and willingness-to-pay for individuals for volunteer water quality monitoring programs. The study involves supporting water quality monitoring at two ponds in the state of Rhode Island. The paper uses both a hypothetical and a real-payment contingent valuation survey to directly measure individual preferences and willingness-to-pay (WTP) for volunteer water quality monitoring at the two ponds. The overall results of the study suggest that hypothetical WTP is not statistically greater than real WTP, and that the average survey respondent is willing to support water quality monitoring on one of the two ponds. The study also finds that the specified purpose of water quality monitoring and certain socioeconomic...

Trade liberalization and the environment: The case of agriculture in South Africa AgEcon
Hassan, Rashid M..
An input-output framework with environmental accounting module was used to investigate the implications of liberalising agricultural trade on the environment in South Africa. The results showed that trade liberalisation in the case of agricultural commodities will lead to environmental improvement. The empirical multi-sector model results were consistent with theoretical results obtained from comparative-statics partial-equilibrium trade models for the case of goods the production of which is associated with environmental externality and their domestic prices above world prices. The study suggested a general equilibrium approach, allowing for more flexible structure of substitution in demand and supply, output composition response, income effects and...

Should we combine incentive payments and tendering for efficiently purchasing conservation services from landholders? AgEcon
Schilizzi, Steven; Breustedt, Gunnar; Latacz-Lohmann, Uwe.
Policy makers aiming to get private landholders to provide non-marketed environmental services need to provide efficient economic incentives. Two ideas have been explored to achieve this: linking contract payments to environmental outcomes and putting the contracts up for tender. This paper investigates whether there are any gains to be had by combining the benefits of both approaches. Landholder risk aversion may offset incentive effects if the fall in participation outweighs any increases in individual effort. Using controlled lab experiments in two countries and across four subject groups, and systematically varying the rate at which payments are linked to uncertain outcomes, this paper clarifies the conditions under which incentives overcome...

Climate Change, Risk and Grain Production in China AgEcon
Holst, Rainer; Yu, Xiaohua; Grun, Carola.
This paper employs the production function-based method proposed by Just and Pope (1978, 1979) to explicitly analyze production risk in the context of Chinese grain farming and climate change, and test for a potential endogeneity of climate factors in Chinese grain production. Our results indicate that China might, at least in the short run, become a net beneficiary of climate change. In particular, we find that increases in annual average temperature increase mean output at the margin and at the same time lead to a reduction of production risk. Further calculations suggest that a 1 °C increase in annual average temperature would entail an economic benefit of $1.1 billion due to the increasing mean output. Furthermore, a Hausman test...

Management of Resources for Sustainable Agriculture AgEcon
Malik, D.P.; Rai, K.N.; Dhanda, S..
Green Revolution triggered in India with the introduction of high yielding varieties of crops particularly wheat and rice in seventies. The cultivators rapidly adopted these varieties in North India, which produced high yields by greatly responding to modern inputs, generation of suitable crop production and protection technologies and favourable public policies. But continuation of same cropping patterns over the last three decades with inefficient and indiscriminate use of agro-chemicals inputs as well as natural resources have resulted into mounting environmental problems. The shrinking of natural resources coupled with technology and public policy related problems have caused increase in cost of production over the years. Considering various factors...

Environmental triage decisions during a drought AgEcon
Gorddard, Russell J.; Connor, Jeffery D.; Ranjan, Ram.
The Murray Darling Basin Current is currently in drought. There are low water levels in most dams, and increased uncertainty about future rainfall. As a result management of the ecosystems in the basin that depend on river flows involves some hard decisions about what assets to save and what assets to let go. This paper models this triage problem using a stochastic and dynamic programming approach. This model is used to identify how optimal management is affected by hysteretic and irreversible effects of drought on ecosystem assets and uncertainty about future climate.

Balanced Scorecard em uma Propriedade Pecuária AgEcon
Brisolara, Claudio Silveira.
A crescente exposição das empresas agropecuárias aos riscos do ambiente externo, que se somam aos riscos climáticos e biológicos, tem suscitado a utilização de novos sistemas de gerenciamento nas empresas rurais. A premência da modernização das técnicas de gestão, por meio da utilização ferramentas simples e efetivas de controle e planejamento dos empreendimentos, foi a motivação principal desse estudo. Foi desenvolvida uma pesquisa exploratória, por meio de um estudo de caso, visando propor um sistema gerencial para uma propriedade dedicada à bovinocultura de corte no Rio Grande do Sul, a partir do referencial metodológico do Balanced Scorecard – BSC. Os resultados encontrados mostraram que há viabilidade de adaptação do BSC às empresas pecuárias, tendo...

'Second-Best' Adjustments to Externality Estimates in Electricity Planning with Competition AgEcon
Burtraw, Dallas; Palmer, Karen L.; Krupnick, Alan J..
A number of state public utility commissions are using "social costing" methods to consider externalities in electricity resource planning. The most comprehensive and formal method is the use of monetary place-holders in the financial evaluation of new investments and potentially in system dispatch to reflect quantitative estimates of externality values. This approach necessarily must take existing environmental and social regulation as given. Furthermore, regulated utilities face increasing competition from electricity generators outside their service territory who may not be affected by social costing. The lack of universal and uniform social costing places PUC actions soundly in the realm of "second-best policy" and they may have unintended consequences...

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....
