Valoração contingente da Área de Proteção Ambiental (APA) São José – MG: um estudo de caso AgEcon
Cirino, Jader Fernandes; Lima, Joao Eustaquio de.
The São José Environmental Protection Area (EPA) in the State of Minas Gerais has a rich natural and historical patrimony. However, in spite of its value and of being a protection area since 1981, it has now suffering several degradations. In that sense, the major objective of this work is to value São José EPA with the purpose of supplying subsidies for the elaboration and attainment of public and private projects of preservation or sustainable exploration of the referred asset, as well as for public policy directed to its administration. As valuation method, it was used the contingent valuation through the approach of Hanemann (1984) and the bootstrapping method to obtain a monthly willingness-to-pay (WTP) per family of the municipal districts that...

The Determinants of the Brazilian Farm Prices AgEcon
Spolador, Humberto Francisco Silva; Barros, Geraldo Sant'Ana de Camargo; Bacchi, Mirian Rumenos Piedade.
The findings presented in this paper come from our study of the effects of Brazilian macroeconomic policy on the Brazilian Farm [product] Price Index using an adapted version of Frankel’s (1986 & 2006) theoretical model. The study examined the connection between Brazilian farm prices and external variables (worldwide importation of agribusiness products, international commodity prices, and foreign real interest rates) and between Brazilian farm prices and domestic variables (GDP, the real exchange rate, and local interest rates).
Tipo: Conference Paper or Presentation Palavras-chave: Brazilian farm prices; Interest rate differentials; International commodity prices and exchange rate.; Agribusiness; Political Economy; Q; E4; E5.

Impact of the New Standard Reinsurance Agreement (SRA) on Multi-Peril Crop Insurance (MPCI) Gain and Loss Probabilities AgEcon
Vergara, Oscar; Seaquist, Jack; Zuba, Gerhard; Harrigan, Matthew; Lee, Eric.
We utilize an agricultural model that uses crop/weather relationships at the county resolution and fits robust distributions that take into account the impact that weather has on crop production. Once the crop insurance policy conditions and prices are applied to the modeled county yield distributions, the portfolio gain and losses can be calculated by aggregating the gain and losses at the county level, state level, regional level and nationwide level. Portfolio losses are computed under the old and new SRA rules and regulations for comparison purposes.

C&T e I para a produção agropecuária brasileira: mensurando e qualificando gastos públicos AgEcon
Batalha, Mario Otavio; Chaves, Gisele de Lorena Diniz; Souza Filho, Hildo Meirelles de.
Few researches in Brazil have undertaken the issue of quantification and qualification of public expenditure in S&T and Innovation devoted to agriculture and livestock. This paper presents an innovative evaluation and provides inedited information for public and private decision makers. Expenditure undertook by 48 Brazilian research organizations was evaluated. This set of organizations comprised the universe of federal and state institutes and agencies, as well as some other non-profit organizations, which gave support to research in agriculture and livestock. The results showed that the role played by Embrapa is of primary importance to the National System of Agricultural Research. Some deficiencies and barriers to scientific and technological...

Optimal control of spatial-dynamic processes: The case of biological invasions AgEcon
Epanchin-Niell, Rebecca S.; Wilen, James E..
This study examines the spatial nature of optimal bioinvasion control. We develop and parameterize a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal control strategies. We find that the qualitative nature of optimal strategies depend in interesting ways on aspects of landscape and invasion geometry. For example, we show that reducing the extent of exposed invasion edge, through spread, removal, or strategically employing landscape features, can be an optimal strategy because it reduces long-term containment costs. We also show that optimal invasion control is spatially and temporally “forward-looking” in the sense that strategies should be targeted to slow the...

An Iterative Auction for Spatially Contiguous Land Management: An Experimental Analysis AgEcon
Banerjee, Simanti; Shortle, James S.; Kwasnica, Anthony M..
Tackling the problem of ecosystem services degradation is an important policy challenge. Different types of economic instruments have been employed by conservation agencies to meet this challenge. Notable among them are Payment for Ecosystem Services (PES) schemes that pay private landowners to change land uses to pro-environmental ones on their properties. This paper focuses on a PES scheme – an auction for the cost-efficient disbursal of government funds for selection of spatially contiguous land management projects. The auction is structured as an iterative descending price auction where every bid is evaluated on the basis of a scoring metric – a benefit cost ratio. The ecological effectiveness and economic efficiency of the auction is tested with data...

A Comparison of the Great Mississippi River Floods of 1993 and 2011: Implications for Crop Insurance and Reinsurance AgEcon
Vergara, Oscar.
The flooding situation in 2011 is similar in nature to the Great Mississippi Flood of 1993, but different in the particulars. First, the timing of the flood within the growing season is different. Second, the two floods occurred in different regions, with the 1993 flood affecting a portion of the Corn Belt and the 2011 flood affecting a region farther south. While floodwaters have inundated several million acres of cropland in 2011, yield losses from delayed planting are expected to be limited. Furthermore, the affected states from the current flood are primarily Group 2 states under the current SRA, which are provided with greater reinsurance protection by the government than the Group 1 states.

Analysis of Spatial Variation in Flood Risk Perception AgEcon
Atreya, Ajita; Susana, Ferreira.
We use hedonic property models to estimate the spatial variation in flood risk in the city of Albany, GA. In addition to knowing whether a property is in the floodplain, we have a unique dataset with actual inundation maps from tropical storm Alberto that hit Albany in 1994. In the absence of information on the structural damages caused by a flood, having information on the actual inundated area can be useful to tease out information effect of a new flood from potential reconstruction cost. We find that the discount in actually inundated properties is larger which supports our hypothesis that homeowners respond better to what they have visualized (“seeing is believing”) and also the potential reconstruction cost in addition to information effect is...

The challenge of environmental monitoring: the example of HNV farmland AgEcon
Peppiette, Zelie.
Assessment of the environmental outcomes associated with agricultural and rural policy is becoming increasingly important. The High Nature Value (HNV) Farmland indicator included within the EU's Common Monitoring and Evaluation Framework for rural development is taken as an example of the parameters used for environmental monitoring. The different methods used across the EU to estimate the extent and condition of HNV farmland are compared, and issues and challenges related to different approaches are discussed.

A Comparison of Methodologies for Valuing Decreased Health Effects from Wildfire Smoke AgEcon
Richardson, Leslie; Loomis, John B.; Champ, Patricia A..
Wildfire seasons are becoming longer and more intense throughout the world, making it increasingly important to monetize the full damages caused by wildfires when analyzing various fire management policies. We estimate the economic costs of the health effects associated with exposure to wildfire smoke using a simple cost of illness approach and for the first time to our knowledge we estimate willingness-to-pay (WTP) for a decrease in symptom days from wildfire smoke using the contingent valuation method and the averting behavior method. Comparing estimates across all three common approaches for estimating the economic cost of exposure to an air pollutant is an important contribution to the literature. This study uses data from the largest wildfire in Los...
