Getting the Prices Wrong: The Limits of Market-Based Environmental Policy AgEcon
Ackerman, Frank; Gallagher, Kevin P..
Market based policies are fast becoming the recommended policy panacea for all the world's environmental problems. Implicit in such recommendations is the theory that free markets, adjusted for externalities, can always create an "efficient" allocation of society's resources. As a result, many contemporary policymakers advocate rolling back regulations in order to let the market protect the environment. There is a fundamental distinction between the use of the market as a tool to help achieve society's goals, and as a blueprint for society's goals; the market is a reasonable policy tool but not a reasonable blueprint. The market as blueprint fails because there are significant public purposes that cannot be achieved by prices and markets alone. Five major...

Respuesta productiva y calidad de la carne de corderos suplementados con nopal fresco y deshidratado. Colegio de Postgraduados
Aguilar Yañez, María Isabel.
El objetivo de este estudio fue evaluar el efecto de suplementar con nopal fresco y deshidratado, en la respuesta productiva y calidad de la carne de corderos. Se dividió en dos etapas. La primera en la evaluación del comportamiento productivo, y la segunda, la evaluación de la calidad de la carne. Se utilizaron 27 corderos machos de cruzas comerciales, con peso inicial promedio de 21.4kg, distribuidos homogéneamente en tres grupos de 9 animales, y sacrificados a peso promedio de 37 kg. Los grupos fueron asignados al azar a cada uno de los siguientes tratamientos: (T1) dieta testigo, (T2) dieta con 17 % (base seca) de nopal deshidratado, y (T3) dieta con 17 % (base seca) de nopal fresco. En la primera etapa, se evaluó la digestibilidad in situ de la...

Environmental Conservation and Food Security in Developing Countries: Bridging the Disconnect AgEcon
Ajayi, Olu Clifford; Matakala, Patrick.
In many developing countries, environmental issues are often sacrificed for immediate food production requirements because of perceived tradeoff between two. Some production systems exist however that offers opportunities for achieving the two seemingly divergent objectives because they have the characteristics to produce joint outputs; food production and environmental conservation, but their adoption in farming communities is socially sub-optimal despite proven technological success. Using natural resource economics framework, this study highlights the reasons for the low adoption of such technologies taking Agroforestry technologies as a case study and, uses externality theory to provide environmental economic logic for developing incentives to...

Influencia social y sostenibilidad en el uso de recursos renovables AgEcon
Almudi, Isabel; Choliz, Julio Sanchez.
En este trabajo presentamos un modelo en el que las actividades extractivas referidas a un recurso natural renovable, si son abusivas, generan algún tipo de reacción social que modifica las preferencias sociales. Esta modificación es tenida en cuenta por el planificador a la hora de decidir cual es la asignación intertemporal óptima entre consumo y stock del recurso. Bajo estas nuevas condiciones, nos preguntamos cómo cambia el stock del recurso natural en el estado estacionario y qué puede decirse acerca de la posibilidad de sobreexplotación en comparación con los modelos tradicionales en los que no se considera reacción social. Los resultados obtenidos muestran que bajo estas nuevas condiciones el stock del estado estacionario aumenta y el comportamiento...

CARACTERIZAÇÃO DOS ASPECTOS E IMPACTOS ECONÔMICOS, SOCIAIS E AMBIENTAIS DO SETOR SUCROALCOOLEIRO PAULISTA. AgEcon
Alvarenga, Rafael Pazeto; Queiroz, Timoteo Ramos.
O presente trabalho tem como objetivo a caracterização dos aspectos e impactos econômicos, sociais e ambientais da monocultura da cana-de-açúcar. Isso servirá para que posteriormente se possa fazer um estudo sobre os impactos que a monocultura da cana acarretará a região de Tupã/SP. Em sua confecção foram consultados sites governamentais, teses e dissertações como também bibliografia pertinente ao tema. Os problemas sociais e ambientais causados pela cana nem sempre recebem o destaque merecido. O setor sucroalcooleiro é a fonte de renda de milhares de trabalhadores e o responsável pela produção de um combustível limpo e renovável. No entanto, a forma como a mão-de-obra é utilizada no corte da cana é exaustiva e degradante. Seus subprodutos vinhaça e...

Continuing the Tradition: Employing Tested and Emerging Economic Tools in Framing Sustainability Challenges for a Global Economy AgEcon
Amanor-Boadu, Vincent; Ross, R. Brent.
Economists have been successful in bringing their definitional and analytical tools to many of the problems that have confronted society over the past century and more, from Smith’s explanation of how nations produce wealth to Arrow’s explanation of the impossibility of social choice and Keynes’ general theory of money and interest. With the issue of sustainability, we draw on economic agents’ attempts at rational choice under uncertainty to understand the opportunities and challenges. We argue that employing system dynamic modeling approach to the problem could offer careful assessment of the soundness of sustainability strategies.

Aligning Key Concepts for Global Change Policy: Robustness, Resilience, and Sustainability Ecology and Society
Anderies, John M; Arizona State University; m.anderies@asu.edu; Folke, Carl; Beijer Institute for Ecological Economics; Stockholm Resilience Center, Stockholm University; carl.folke@beijer.kva.se; Walker, Brian; CSIRO Ecosystem Science; Brian.Walker@csiro.au; Ostrom, Elinor; Indiana University; ostrom@indiana.edu.
Globalization, the process by which local social-ecological systems (SESs) are becoming linked in a global network, presents policy scientists and practitioners with unique and difficult challenges. Although local SESs can be extremely complex, when they become more tightly linked in the global system, complexity increases very rapidly as multi-scale and multi-level processes become more important. Here, we argue that addressing these multi-scale and multi-level challenges requires a collection of theories and models. We suggest that the conceptual domains of sustainability, resilience, and robustness provide a sufficiently rich collection of theories and models, but overlapping definitions and confusion about how these conceptual domains articulate with...

Geotraceability: an innovative strategy for extraction of information and an aid for the sustainable cattle raising. Repositório Alice
ANDRADE, R. G.; BATISTELLA, M.; PIRES, P. P.; VISOLI, M. C.; AMARAL, T. B..
Abstract The requirement of traceability of information for food is an increasingly important condition for gaining the confidence and loyalty of the consumer. The concept of geotraceabil ity arose through the association between knowledge of a geographical nature with the traditional information provided by traceability. This study explored the use of design of spatial information inherent to biophysical parameters of the pasture (vegetation indices and evapotranspiration) combined with data collection on the mobility of cattle in pasture areas for extraction and availability of spatially explicit information that can assist sustainable cattle production. From the trajectories, it was observed the existence of a typical behavioral pattern of the animals,...

Energy Demand in Agricultural Biomass Production in Parana state, Brazil CIGR Journal
Andrea, M. C. S.; Tieppo, R. C.; Gimenez, L. M.; Povh, F. P.; Katsman, T. J.; Romanelli, T. L..
Energy flow analysis is an interesting approach to assess and to improve sustainability of agricultural production systems, represented by the economy of energy resources and other inputs translated into energy terms. This type of analysis can complement the economic view contributing to more efficient production systems. Moreover, assessing crops with traditional food use may play an important role in energy provision. Energy efficiency tools were applied in order to determine the energy demand as well as the efficiency of the biomass production of several forage crops in mechanized systems conducted at Paraná state, Brazil. Material flow, input and output energy, energy balance, energy return over investment and embodied energy were used and identified...

Energetic analysis of landrace varieties and hybrids of corn produced in different technological levels of management REA
Araujo,Alisson V. de; Brandão Junior,Delacyr da S.; Colen,Fernando.
The aim of this study was to analyze, under the energetic point of view, the cultivation of corn in three management systems (low, medium and high-tech), using two landrace varieties ('Argentino' and 'BR da Várzea'), a double hybrid cultivar (SHS 4080) and a simple hybrid (IAC 8333). Five performance indicators were used: energy efficiency, liquid cultural energy, cultural efficiency, energy balance and productive energy efficiency. From the perspective of family farming, it was verified the largest social importance of the systems under low and medium levels of technology, due to the increase employment capacity of rural labor. The liquid cultural energy and energy balance were more favorable for the system under high technological level, unlike cultural...

A Global Mitigation Hierarchy for Nature Conservation ArchiMer
Arlidge, William N. S.; Bull, Joseph W.; Addison, Prue F. E.; Burgass, Michael J.; Gianuca, Dimas; Gorham, Taylor M.; Jacob, Celine; Shumway, Nicole; Sinclair, Samuel P.; Watson, James E. M.; Wilcox, Chris; Milner-gulland, E. J..
Efforts to conserve biodiversity comprise a patchwork of international goals, national-level plans, and local interventions that, overall, are failing. We discuss the potential utility of applying the mitigation hierarchy, widely used during economic development activities, to all negative human impacts on biodiversity. Evaluating all biodiversity losses and gains through the mitigation hierarchy could help prioritize consideration of conservation goals and drive the empirical evaluation of conservation investments through the explicit consideration of counterfactual trends and ecosystem dynamics across scales. We explore the challenges in using this framework to achieve global conservation goals, including operationalization and monitoring and compliance,...

The Interplay of Well-being and Resilience in Applying a Social-Ecological Perspective Ecology and Society
Armitage, Derek; University of Waterloo; derek.armitage@uwaterloo.ca; Charles, Anthony T; Saint Mary's University; Tony.Charles@SMU.CA; Johnson, Derek; University of Manitoba; derek_johnson@umanitoba.ca; Allison, Edward H; The WorldFish Center and the University of East Anglia; e.allison@cgiar.org.
Innovative combinations of social and ecological theory are required to deal with complexity and change in human-ecological systems. We examined the interplay and complementarities that emerge by linking resilience and social well-being approaches. First, we reflected on the limitations of applying ecological resilience concepts to social systems from the perspective of social theory, and particularly, the concept of well-being. Second, we examined the interplay of resilience and well-being concepts in fostering a social-ecological perspective that promises more appropriate management and policy actions. We examined five key points of interplay: (1) the limits of optimization thinking (e.g., maximum sustainable yield), (2) the role of human agency and...

Can Resilience be Reconciled with Globalization and the Increasingly Complex Conditions of Resource Degradation in Asian Coastal Regions? Ecology and Society
Armitage, Derek; Wilfrid Laurier University; darmitag@wlu.ca; Johnson, Derek; Centre for Maritime Research; dsjohnson@marecentre.nl.
This paper explores the relationship between resilience and globalization. We are concerned, most importantly, with whether resilience is a suitable conceptual framework for natural resource management in the context of the rapid changes and disruptions that globalization causes in social-ecological systems. Although theoretical in scope, we ground this analysis using our experiences in two Asian coastal areas: Junagadh District in Gujarat State, India and Banawa Selatan, in Central Sulawesi, Indonesia. We present the histories of resource exploitation in the two areas, and we attempt to combine a resilience perspective with close attention to the impact of globalization. Our efforts serve as a basis from which to examine the conceptual and practical...

ABSTRACT The aim of this study was to analyze the potential use of açaí seeds as an alternative ingredient in the feed of slow-growth broilers until 28 days of age. We carried out a bromatological analysis of fractions of the açaí fruit. The açaí seed without mesocarp was the best choice for formulation of the açaí seed bran (ASB), which was evaluated in terms of bird performance and economic viability of the supplemented feed. A total of 416 male chicks of the French Red-Naked Neck lineage were used in a completely randomized design with four treatments (0, 2, 6 and 10% inclusion of ASBin the feed) with eight replicates each. The results indicated that ASB can be included in proportions of up to 10% in the diet of slow growth broilers at early development...

Sustainable food versus health concerns AgEcon
Avermaete, T.; Mathijs, Erik.
Simultaneous with the growing demand for sustainable food, statistics in all EU member states report consumption patterns that are characterized by too much fat, overdoses of sugar and a lack of fruits and vegetables. The streams of literature that investigate the factors influencing sustainable food consumption and healthy food consumption are largely separated. However, the question whether there is a positive relationship between consumer behaviour towards sustainable food and consumer behaviour towards healthy food remains largely unanswered. The purpose of this paper is to examine the relationship between the consumption of different types of sustainable food on the one hand, and healthy food patterns on the other. The study is based on a sample of...
