Articulacão dos interesses públicos e privados no pólo Petrolina-PE/Juazeiro-BA: em busca de espaço no mercado globalizado de frutas frescas. Repositório Alice
SILVA, P. C. G. da.
O trabalho analisa as formas de articulação dos interesses privados e do setor público que foram e são determinantes para o impulso da fruticultura do plo Petrolina-PE/Juazeiro-BA. Demonstra-se que três dinâmicas distintas concorreram para reestruturação produtiva e recomposição da base econômica e social da região objeto de estudo: a) as transformações decorrentes do processo de globalização da economia no âmbito da agricultura e da alimentação, com a emergência das cadeias internacionais de suprimento de produtos frescos de alta qualidade; b) os investimentos públicos e privados na irrigação, impulsionando o desenvolvimento local e regional, e c) a organização de uma representação de interesses privados capaz de interagir com o Estado, ocupar espaços...

Bridging the Gap Between Economics and Ecology Ecology and Society
Leefers, Larry; Michigan State University; leefers@pilot.msu.edu; Castillo, Gem; Michigan State University; Castil16@pilot.msu.edu.
Economics and ecology are often presented as opposing disciplines. Both fields have strengths and weaknesses. A new transdisciplinary field, ecological economics, attempts to bring together the strengths of both disciplines with a vision for a sustainable future. In this paper, we focus on one particular concept championed by ecological economists, natural capital. In particular, our interest is on the institutionalization of this concept through the United Nation's Satellite System for Integrated Environmental and Economic Accounting (SEEA). SEEA is an international convention that incorporates natural resource accounting as a complement to the traditional System of National Accounts (SNA). In the case of boreal forests, the stocks and flows of forest...

Ecological and Social Dynamics in Simple Models of Ecosystem Management Ecology and Society
Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu; Brock, William; University of Wisconsin; brock@macc.wisc.edu; Hanson, Paul; University of Wisconsin; pchanson@facstaff.wisc.edu.
Simulation models were developed to explore and illustrate dynamics of socioecological systems. The ecosystem is a lake subject to phosphorus pollution. Phosphorus flows from agriculture to upland soils, to surface waters, where it cycles between water and sediments. The ecosystem is multistable, and moves among domains of attraction depending on the history of pollutant inputs. The alternative states yield different economic benefits. Agents form expectations about ecosystem dynamics, markets, and/or the actions of managers, and choose levels of pollutant inputs accordingly. Agents have heterogeneous beliefs and/or access to information. Their aggregate behavior determines the total rate of pollutant input. As the ecosystem changes, agents update their...

Ecological-economic modelling for the sustainable management of biodiversity ArchiMer
Doyen, Luc; Cisse, Abdoul; Gourguet, Sophie; Mouysset, L.; Hardy, Pierre-yves; Bene, Christophe; Blanchard, Fabian; Jiguet, Frederic; Pereau, J.-c.; Thebaud, Olivier.
Terrestrial and marine biodiversity provides the basis for both ecosystems functioning and numerous commodities or services that underpin human well-being. From several decades, alarming trends have been reported worldwide for both biodiversity and ecosystem services. Therefore the sustainable management of biodiversity requires a double viewpoint balancing ecological conservation with the welfare of human societies. Understanding the underlying trade-offs, synergies and interactions imposes the development of interdisciplinary researches and methods. In that respect, bio-economic or ecological economic modeling is likely to play a major role. The present paper intends to elicit the key features, strengths and challenges of bio-economic approaches...

Ecoviability for ecosystem-based fisheries management ArchiMer
Doyen, Luc; Bene, Christophe; Bertignac, Michel; Blanchard, Fabian; Cisse, Abdoul; Dichmont, Catherine; Gourguet, Sophie; Guyader, Olivier; Hardy, Pierre-yves; Jennings, Sarah; Little, Lorne Richard; Macher, Claire; Mills, David Jonathan; Noussair, Ahmed; Pascoe, Sean; Pereau, Jean-christophe; Sanz, Nicolas; Schwarz, Anne-maree; Smith, Tony; Thebaud, Olivier.
Reconciling food security, economic development and biodiversity conservation is a key challenge, especially in the face of the demographic transition characterizing many countries in the world. Fisheries and marine ecosystems constitute a difficult application of this bio-economic challenge. Many experts and scientists advocate an ecosystem approach to manage marine socio-ecosystems for their sustainability and resilience. However, the ways by which to operationalize ecosystem-based fisheries management (EBFM) remain poorly specified. We propose a specific methodological framework-viability modelling-to do so. We show how viability modelling can be applied using four contrasted case-studies: two small-scale fisheries in South America and Pacific and two...

Emergence Unites Ecology and Society Ecology and Society
Trosper, Ronald L; University of British Columbia; Ronald.Trosper@ubc.ca.
The effort to combine analysis of ecosystems and social systems requires a firm theoretical basis. When humans are present in an ecosystem, their actions affect emergent structures; this paper examines forms of emergence that account for the presence of humans. Humans monitor and regulate ecosystems based on their cultural systems. Cultural systems consist of concepts linked in complicated ways that can form consistent world views, can contain inconsistencies, and may or may not accurately model the properties of a social–ecological system. Consequently, human monitoring and regulating processes will differ, depending on cultural systems. Humans, as agents, change or maintain pre-existing material and cultural emergent structures. The...

Open-Cycle Hatcheries, Tourism and Conservation of Sea Turtles: Economic and Ecological Analysis AgEcon
Tisdell, Clement A.; Wilson, Clevo.
Considers the role that tourism-based sea turtle-hatcheries can play in conserving populations of sea turtles by combining economic analysis of markets with ecological parameters. Background is provided on the nature and development of such hatcheries in developing countries, giving particular attention to Sri Lanka. The modelling provided helps with the assessment of the impacts of turtle hatcheries on the conservation of sea turtles and enables ecological consequences of tourism, based on such hatcheries, to be better appreciated than in the absence of such modelling. The results demonstrate that sea turtle hatcheries that operate for tourist purposes can make a positive contribution to sea turtle conservation, but this depends on the manner in which...

Resilience and Restoration of Lakes Ecology and Society
Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu; Cottingham, Kathryn L; ; cottingh@nceas.ucsb.edu.
Lake water quality and ecosystem services are normally maintained by several feedbacks. Among these are nutrient retention and humic production by wetlands, nutrient retention and woody habitat production by riparian forests, food web structures that cha nnel phosphorus to consumers rather than phytoplankton, and biogeochemical mechanisms that inhibit phosphorus recycling from sediments. In degraded lakes, these resilience mechanisms are replaced by new ones that connect lakes to larger, regional economi c and social systems. New controls that maintain degraded lakes include runoff from agricultural and urban areas, absence of wetlands and riparian forests, and changes in lake food webs and biogeochemistry that channel phosphorus to blooms of nuisance...

Spatial management of inshore areas: Theory and practice ArchiMer
Claudet, Joachim; Roussel, S; Pelletier, Dominique; Rey Valette, Hélène.
Coastal uses have deeply evolved these last decades and high anthropogenic pressures on coastal ecosystems have affected the sustainability of these areas with respect to the services and the resources they may provide. Traditional fisheries management has failed to avoid overexploitation of most coastal marine resources. Management measures based on an Integrated Coastal Zone Management (ICZM) are thus required. Spatial management covers various ranges of properties that may enhance usual regulatory means. If spatial considerations are explicitly integrated in fisheries management, the latter may contribute to zoning design in order to balance the economic, social and biological values of natural marine resources. While traditional fisheries management...

The Architecture and Measurement of an Ecosystem Services Index AgEcon
Banzhaf, H. Spencer; Boyd, James.
This paper describes the construction of an ecological services index (ESI). An ESI is meant to summarize and track over time the magnitude of beneficial services arising from the natural environment. A central task of this paper is to define rigorously ecosystem services so that services can be counted in an economically and ecologically defensible manner - a requirement if ecological contributions to welfare are to be incorporated into the national accounts. This paper advocates a particular economic structure and relates it to index theory and makes concrete recommendations for the measurement of such an index.

The Excitement and Value of Discovering Tourism Economics: Clem Tisdell's Journey AgEcon
Tisdell, Clement A..
Outlines how Clem Tisdell came to discover tourism economics and charts the basic route that he followed in developing that interest. This article is developed by first considering his early years (1939 to 1960), that is the period prior to his commencement of postgraduate studies at the Australian National University, then his postgraduate studies at the Australian National University (1961-1963), and his lecturing appointment at this university in the period 1964-1972. It was towards the end of this period that his research interests started to change significantly and provided a springboard for his later focus on tourism economics and the environment. It was during his appointment as Professor of Economics at the University of Newcastle (1972-1989) that...

THE “STOCK AND FLOW” APPROACH TO THE GOVERNANCE OF SELF-SUSTAINABLE RURAL SYSTEMS AgEcon
Pancino, Barbara; Bonaiuti, M.; Franco, Silvio.
The aim of this study is to present the “stock and flow” model - based on the Georgescu-Roegen bio economic paradigm and on the ecological economics principles - in a regional key and to discuss the implications of such an approach on the local system governance in order to guarantee a long term economic, social and environmental self-sustainability. These theories give a dynamic characteristic to this approach, by interconnecting the production process (supply) with the responsibilities of the welfare generation (demand). Starting from this theoretical model, it is possible to look at the integrating modes of production and consumption processes at a local scale that consent to guide a rural system towards conditions of sustainability. This perspective of...

Uncertainty in Discount Models and Environmental Accounting Ecology and Society
Ludwig, Donald; University of British Columbia; Ludwig@math.ubc.ca; Brock, William A.; University of Wisconsin-Madison; WBrock@ssc.wisc.edu; Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu.
Cost-benefit analysis (CBA) is controversial for environmental issues, but is nevertheless employed by many governments and private organizations for making environmental decisions. Controversy centers on the practice of economic discounting in CBA for decisions that have substantial long-term consequences, as do most environmental decisions. Customarily, economic discounting has been calculated at a constant exponential rate, a practice that weights the present heavily in comparison with the future. Recent analyses of economic data show that the assumption of constant exponential discounting should be modified to take into account large uncertainties in long-term discount rates. A proper treatment of this uncertainty requires that we consider returns...

Understanding Complex Human Ecosystems: The Case of Ecotourism on Bonaire Ecology and Society
Abel, Thomas; National Taipei University; tabel@mail.ntpu.edu.tw.
It is suggested that ecotourism development on the island of Bonaire can be productively understood as a perturbation of a complex human ecosystem. Inputs associated with ecotourism have fueled transformations of the island ecology and sociocultural system. The results of this study indicate that Bonaire's social and economic hierarchy is approaching a new, stable systems state following a 50-yr transition begun by government and industry that stabilized with the appearance of ecotourism development and population growth. Ecotourism can be understood to have "filled in" the middle of the production hierarchy of Bonaire. Interpreted from this perspective, population growth has completed the transformation by expanding into production niches at smaller...

Variance as a Leading Indicator of Regime Shift in Ecosystem Services Ecology and Society
Brock, William A; University of Wisconsin-Madison; WBrock@ssc.wisc.edu; Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu.
Many environmental conflicts involve pollutants such as greenhouse gas emissions that are dispersed through space and cause losses of ecosystem services. As pollutant emissions rise in one place, a spatial cascade of declining ecosystem services can spread across a larger landscape because of the dispersion of the pollutant. This paper considers the problem of anticipating such spatial regime shifts by monitoring time series of the pollutant or associated ecosystem services. Using such data, it is possible to construct indicators that rise sharply in advance of regime shifts. Specifically, the maximum eigenvalue of the variance-covariance matrix of the multivariate time series of pollutants and ecosystem services rises prior to the regime shift. No...
