Ajustes de funções de distribuição de probabilidade à radiação solar global no Estado do Rio Grande do Sul. Repositório Alice
CARGNELUTTI FILHO, A.; MATZENAUER, R.; TRINDADE, J.K. da..
O objetivo deste trabalho foi verificar o ajuste das séries de dados de radiação solar global média decendial, de 22 municípios do Estado do Rio Grande do Sul, às funções de distribuições de probabilidade normal, log-normal, gama, gumbel e weibull. Aplicou-se o teste de aderência de Kolmogorov-Smirnov, nas 792 séries de dados (22 municípios x 36 decêndios) de radiação solar global média decendial, para verificar o ajuste dos dados às distribuições normal, log-normal, gama, gumbel e weibull, totalizando 3.960 testes. Os dados decendiais de radiação solar global média se ajustam às funções de distribuições de probabilidade normal, log-normal, gama, gumbel e weibull, e apresentam melhor ajuste à função de distribuição de probabilidade normal.

Avaliação dos componentes da pegada ecológica brasileira no contexto mundial e o papel da bovinocultura. Repositório Alice
FASIABEN, M. do C. R.; MAIA, A. G.; BARIONI, L. G.; LAZOU, J..
O presente trabalho trata da relevância de ações de enfrentamento das condicionantes ambientais ligadas à pecuária brasileira, como forma de alavancar seu crescimento com o mínimo de danos ao meio ambiente. O indicador ambiental Pegada Ecológica (PE) expressa a pressão do consumo humano sobre o meio ambiente, no Brasil e no mundo. A partir de dados internacionais da Global Footprints Network procedeu-se ao agrupamento de países segundo a participação de cada um dos principais componentes que integram a PE. Cinco grupos foram encontrados, estando o Brasil enquadrado naquele que se caracteriza pela predominância de uma bovinocultura extensiva em pastagens e, relativamente, baixo consumo de energia fóssil (grupo 3). No caso brasileiro, o componente...

Is Area Yield Insurance Competitive with Farm Yield Insurance? AgEcon
Barnett, Barry J.; Black, J. Roy; Hu, Yingyao; Skees, Jerry R..
This article compares risk reduction from MPCI and GRP crop insurance contracts. The analysis extends and improves on the existing area-yield insurance literature in four important respects. First, the geographical scope greatly exceeds that of previous work. Second, unlike previous efforts, the area is not assumed to consist only of those farms included in the analysis. Third, the analysis is based on the actual GRP indemnity function rather than the area-yield indemnity function commonly used in the literature. Fourth, the analysis avoids the questionable assumption that GRP scale can be optimized at the individual farm level. Even with a number of conservative assumptions favoring MPCI relative to GRP, results indicate that at least for some crops and...

Mainstreaming ecosystem-based adaptation: transformation toward sustainability in urban governance and planning Ecology and Society
Wamsler, Christine; Lund University Centre for Sustainability Studies (LUCSUS), Sweden; Centre for Societal Resilience (CSR), Sweden; Global Urban Research Centre (GURC), Manchester University, UK; christine.wamsler@lucsus.lu.se.
The concept of ecosystem-based adaptation is advocated at international, national, and regional levels. The concept is thought to foster sustainability transitions and is receiving increasing interest from academic and governmental bodies alike. However, there is little theory regarding the pathways for its systematic implementation. It furthermore remains unclear to what degree the concept is already applied in urban planning practice, how it is integrated into existing planning structures and processes, and what drivers exist for further integration. Against this background, this study examines potential ways to sustainably mainstream ecosystem-based adaptation into urban planning. Eight municipalities in Southern Germany were investigated to analyze the...

MEASURING CONSUMER BENEFITS OF FOOD SAFETY RISK REDUCTIONS AgEcon
Buzby, Jean C.; Fox, John A.; Ready, Richard C.; Crutchfield, Stephen R..
Microbial pathogens and pesticide residues in food pose a financial burden to society which can be reduced by incurring costs to reduce these food safety risks. We explore three valuation techniques that place a monetary value on food safety risk reductions, and we present a case study for each: a contingent valuation survey on pesticide residues, an experimental auction market for a chicken sandwich with reduced risk of Salmonella, and a cost-of-illness analysis for seven foodborne pathogens. Estimates from these techniques can be used in cost/benefit analyses for policies that reduce food safety risks.
Tipo: Journal Article Palavras-chave: Contingent valuation; Cost of illness; Experimental auction market; Food safety; Risk reduction; Salmonella; Food Consumption/Nutrition/Food Safety.

Ecosystem-based approaches for climate change adaptation are promoted at international, national, and local levels by both scholars and practitioners. However, local planning practices that support these approaches are scattered, and measures are neither systematically implemented nor comprehensively reviewed. Against this background, this paper advances the operationalization of ecosystem-based adaptation by improving our knowledge of how ecosystem-based approaches can be considered in local planning (operational governance level). We review current research on ecosystem services in urban areas and examine four Swedish coastal municipalities to identify the key characteristics of both implemented and planned measures that support ecosystem-based...

Pride of the South: Risk Analysis for Marine Biosecurity in Fiordland AgEcon
Sinner, Jim; Roberts, Bethany; Piola, Richard.
This paper describes a model used to assess alternative scenarios for managing the marine biosecurity risk to Fiordland from vessel traffic. Scenarios are assessed in terms of risk reduction per dollar spent. To keep the analysis manageable, we focus on vessel risks from hull fouling, as this is considered the primary pathway of vessel-related spread. Our analysis includes evaluation of the costs and benefits of different types of vector treatment as well as the possibility of continued vessel monitoring and control of pest populations in Bluff Harbour to reduce the risk of vector infection.
Tipo: Conference Paper or Presentation Palavras-chave: Fiordland; Marine biosecurity; Risk reduction; Benefit cost analysis; Management options; Bluff; Agricultural and Food Policy; Environmental Economics and Policy; Food Security and Poverty; Health Economics and Policy; Land Economics/Use; Livestock Production/Industries; Research Methods/ Statistical Methods.

Territorial risks analysis by transboundary animal diseases in Cuba Rev Salud Anim.
Percedo,María Irian; González,Isel; Chávez,Pablo R; Delgado,Carlos; Abeledo,María Antonia.
A methodology for the territorial risk analysis of biological disasters due to transboundary animal diseases (TADs) was developed and conducted in all municipalities in the country. The methodology identifies the relevant places for the potential entry and the following spreading of TADs (objectives with biological risk-OBR), and characterizes the level of their vulnerability (sanitary gaps) as well as that of the local animal populations. The vulnerability of animal populations considers many topics divided into four aspects: structure of animal production, sanitary control, urbanization of animal rearing, and general characteristics of the municipality. In 161 municipalities, 1597 OBRs were identified. Few municipalities were classified at the highest...

Tradeoffs in the quest for climate smart agricultural intensification in Mato Grosso, Brazil. Repositório Alice
GIL, J. D. B.; GARRETT, R. D.; ROTZ, A.; DAIOGLOU, V.; VALENTIM, J. F.; PIRES, G. F.; COSTA, M. H.; LOPES, L. B.; REIS, J. C. dos.
Low productivity cattle ranching, with its linkages to rural poverty, deforestation and greenhouse gas (GHG) emissions, remains one of the largest sustainability challenges in Brazil and has impacts worldwide. There is a nearly universal call to intensify extensive beef cattle production systems to spare land for crop production and nature and to meet Brazil?s Intended Nationally Determined Contribution to reducing global climate change. However, different interventions aimed at the intensification of livestock systems in Brazil may involve substantial social and environmental tradeoffs. Here we examine these tradeoffs using a whole-farm model calibrated for the Brazilian agricultural frontier state ofMato Grosso, one of the largest soybean and beef cattle...

Volatilidade dos retornos econômicos associados à integração lavoura-pecuária no Estado do Paraná. Repositório Alice
LAZZAROTTO, J. J.; SANTOS, M. L. dos; LIMA, J. E. de; MORAES, A. de..
O setor agropecuário brasileiro há grande diversidade e heterogeneidade de sistemas de produção, que tendem a ser cercados por amplo número de fatores de riscos. Embora não possam ser completamente eliminados, os riscos podem ser minimizados mediante adoção de algumas estratégias, como a diversificação com atividades agrícolas e pecuárias. Assim, partindo de resultados históricos de pesquisas para a agropecuária do estado do Paraná e utilizando, como medida principal. o value-at -risk (ou valor em risco), analisou-se a volatilidade do retornos econômicos de sistemas com integração lavoura-bovinocultura de corte, diante de sistemas especializados na produção de grãos ou na bovinocultura de corte. As análises apontaram que. no curto prazo. a integração tende...
