Transformation from “Carbon Valley” to a “Post-Carbon Society” in a Climate Change Hot Spot: the Coalfields of the Hunter Valley, New South Wales, Australia Ecology and Society
Evans, Geoffrey R.; University of Newcastle (Australia), Ecosystem Health Research Group; Geoffrey.r.evans@bigpond.com.
This paper examines the possibilities for transformation of a climate-change hot spot—the coal-producing Hunter Region of New South Wales, Australia—using complex adaptive systems (CAS) theory. It uses CAS theory to understand the role of coal in the region’s history and efforts to strengthen the ecological, economic, and social resilience of the region’s coal industry in the face of demands for a shift from fossil fuel dependency to clean, renewable energy and genuine resilience and sustainability. It uses CAS theory to understand ways in which the resilience of two alternative futures, labeled “Carbon Valley” and “Post-Carbon Society” (Heinberg 2004), might evolve. The...

Global environmental change requires responses that involve marked or qualitative changes in individuals, institutions, societies, and cultures. Yet, while there has been considerable effort to develop theory about such processes, there has been limited research on practices for facilitating transformative change. We present a novel pathways approach called Three Horizons that helps participants work with complex and intractable problems and uncertain futures. The approach is important for helping groups work with uncertainty while also generating agency in ways not always addressed by existing futures approaches. We explain how the approach uses a simple framework for structured and guided dialogue around different patterns of change by using examples. We...

Individuals Matter: Exploring Strategies of Individuals to Change the Water Policy for the Tisza River in Hungary Ecology and Society
Werners, Saskia E.; ; werners@mungo.nl; Matczak, Piotr; ; matczak@amu.edu.pl; Flachner, Zsuzsanna ; ; flachner@rissac.hu.
This paper offers a novel interpretation of the introduction of floodplain rehabilitation and rural development into the water policy for the Tisza River in Hungary. It looks at the role of individuals and the strategies that they used to bring about water policy change. Five strategies are explored: developing new ideas, building coalitions to sell ideas, using windows of opportunity, playing multiple venues and orchestrating networks. Our discussion on the importance of each strategy and the individuals behind it is based on interviews, group discussions and a literature review. The international and political attention sparked by a series of floods, dike failure and a major cyanide spill, which preceded national elections, opened a window of opportunity...

Urban water governance regimes around the world have traditionally planned large-scale, centralized infrastructure systems that aim to control variables and reduce uncertainties. There is growing sectoral awareness that a transition toward sustainable alternatives is necessary if systems are to meet society’s future water needs in the context of drivers such as climate change and variability, demographic changes, environmental degradation, and resource scarcity. However, there is minimal understanding of how the urban water sector should operationalize its strategic planning for such change to facilitate the transition to a sustainable water future. We have integrated concepts from transitions, resilience, and institutional theory to develop a...

Short-scale temporal variability of physical, biological and biogeochemical processes in the NW Mediterranean Sea: an introduction ArchiMer
Andersen, V.; Goutx, M.; Prieur, L.; Dolan, J. R..
In the framework of the PROOF-PECHE project (http://www.obs-vlfr.fr/proof/vt/op/ec/peche/pec.htm) a multi-disciplinary team performed experiments and collected samples during the DYNAPROC2 cruise aboard the RV Thalassa from September to October in 2004. The cruise provided data on the functioning of the pelagic food web by sampling over a month long period in the NW Mediterranean Sea at a fixed station subject to weak horizontal advection currents during a period of hydrological stability. This paper describes the background of the cruise and provides an overview of the results derived from the campaign which constitute the special section. The major objective of the cruise was to assess the relative importance and variability of the pathways of carbon in...

The purpose of this paper is to make clear the characteristics of milk processing system in the South-west of Bulgaria and figure out the transition history of milk processing techniques in Bulgaria. It was confirmed that the Bulgarian system shares some techniques in common both with fermented milk processing series and with the solidifying-additives using series. It was considered highly possible that the fermented milk processing series seen in Bulgaria today originated from West Asia. Meanwhile,it was found that some significant differences from the West Asian fermented milk processing series are the Bulgarian one stops at the stage of making fermented milk and butter,without further processing those into cheese and butter oil. This change can be...

コーカサスにおける乳加工体系 : グルジア・アルメニアの農牧民の事例を通して OAK
平田, 昌弘; HlRATA, Masahiro.
To understand milk processing systems in Caucasia and analyze their history,nine households of agro-pastoralists were surveyed in Georgia and Armenia. The techniques of clotting agent using series,fermented milk processing series and cream separating series ware broadly shared among agro-pastoralists over Georgia and Armenia. The characteristics of milk processing systems in Caucasia are 1) the milk processing techniques (clotting agent using series and fermented milk processing series) in Caucasia base on those techniques of West Asia,2) the cream separating series have developed in Caucasia because of its cooler natural environment,3) butter and butter-oil making by the technique of fermented milk processing series became unnecessary,thus the fermented...

Thirty Years of Agricultural Transition in China (1977-2007) and the "New Rural Campaign" AgEcon
Jia, Xiangping; Fock, Achim.
Agriculture in China has experienced a compelling growth in the early 1980s, a buoyant upbeat in the early 1990s, and an extended period of low growth after 1995. Decollectivization, mar-ket reforms, public investments and technology have played a critical role during this overall successful process. However, the transition has also led to increasing inequalities between the agricultural and non-agricultural population, and substantial institutional issues remain to be fully addressed. The Chinese government is now reemphasizing agriculture and rural develop-ment under its New Rural Campaign with the objective to address rural-urban inequalities, but a stronger emphasis on participation and tenure reforms is warranted.

Zur Effizienz landwirtschaftlicher Unternehmen in Brandenburg – Eine Data Envelopment Analysis AgEcon
Balmann, Alfons; Czasch, Britta.
The transition of East German agriculture led to major structural adjustments that showed some very particular phenomena. For instance, most of the successors of the former agricultural production cooperatives (LPGs) make slight losses and they operate at a higher employment level than new and re-established farms. In this paper we try to explain these phenomena with the farms' history prior to the transition period. Particular attention is given to sunk costs, the identity of members and employees, and old debts. A Data Envelopment Analysis of 210 financial statements distributed over the financial years 1992/93 to 1995/96 gives evidence that these historical arguments had a decisive impact on the farms' behaviour. However, this impact decreases over...

COURTS AND CONTRACT ENFORCEMENT IN TRANSITION AGRICULTURE: THEORY AND EVIDENCE FROM POLAND AgEcon
Beckmann, Volker; Boger, Silke.
The paper investigates theoretically and empirically the role of courts for contract enforcement in transition agriculture. In a survey of 306 Polish hog farmers conducted in 1999, only 38.5% of them reported to believe that they could use courts to enforce contracts with their most important customer. Furthermore, those who believe the legal system could be used would accept significant financial losses before taking action. We develop a theoretical model, based on the costs and benefits of court enforcement, which captures the boundary between contracts to be regarded as "enforceable" and "not-enforceable" and, simultaneously, the threshold of taking legal action. The empirical analysis strongly supports our model: (1) the farmers' responds can be...

Institutional Change of the Agricultural Administration and Rural Associations in East Germany before and after Unification AgEcon
Wolz, Axel.
With the collapse of the socialist regime in East Germany in late 1989 and the rising political call for unification in early 1990, a radical and abrupt change of the institutional structure became necessary. Among others, the (agricultural) administration had to be totally restructured. This referred not only to substance, functions and tasks which had to be adjusted, similar to most other transition economies, to the market-economic and pluralistic democratic system, but also the whole administrative set-up had to be re-established in line with the West German system (territorial re-organisation). Hence, a new administrative system had to be built up in the East, while simultaneously the socialist one had to be dismantled. This transformation process...

10 years of transition in Ukraine agriculture: An analysis of productivity and efficiency of enterprises AgEcon
Lissitsa, Alexej; Odening, Martin; Babycheva, Tamara.
This paper analyzes efficiency and total factor productivity (TFP) change of large agricultural enterprises during their transition to a market economy in Ukraine. In this case the efficiency is calculated by data envelopment analysis and the productivity change is measured by the Malmquist Productivity Change Index in the period between 1990 and 1999. On average, TFP declined by 6% annually, dropping a total 42%. The main reason for the observed TFP decline is a decrease in technical efficiency, which is found to be remarkably significant. At the same time there is a high variation among individual enterprises: their distribution of efficiency scores widens, which indicates that the farms diverge with respect to their economic performance. The Tobit...

What Motivates Farms to Associate? The Case of Two Competing Czech Agricultural Associations AgEcon
Bavorova, Miroslava; Curtiss, Jarmila.
The study investigates determinants of affiliation with the two strongest associations in Czech agriculture. These represent Agricultural Association grouping large-scale enterprises and Association of Private Farmers, respectively. Our objective is to analyze whether associations with different types of members (large-scale enterprises vs. private farmers) experience different motives for joining or lapsing. Moreover, we investigate if there are characteristics of the associations' members which positively correlate to membership. The results imply that political lobbying is the main entry incentive for both large-scale enterprises and individual farmers. Informal information exchange is a more significant motivation for private farmers than for...

The Two Transitions in Central and Eastern Europe and the Relation between Path Dependent and Politically Implemented Institutional Change AgEcon
Zweynert, Joachim; Goldschmidt, Nils.
The increasing gap between the formerly socialist countries of Central and Eastern Europe (CE & EE) with regard to both their economic and political performance cannot be explained by their different starting conditions after the breakdown of the Soviet Union alone. Rather, it is due to cultural and historical circumstances that shape the particular tradition and societal environment. Taking a cultural approach and referring to the newer literature on the transfer of institutions, we try to improve the understanding of the interrelation between formal and informal institutions. Our central thesis is that the "reaction rate" of informal institutions depends on their compatibility with imported formal institutions. The transition processes in CE & EE...

Russia's Frangible Tendency to Rise: What Can Be Observed at Macro- and Meta-Level? AgEcon
Voigt, Peter.
This paper is an extraction of some results achieved in a comprehensive study of Russia's transition in its regional as well as sectoral dimension. Thereby, the transition process between 1993 - 2000 has been approximated by aggregated developments of productivity, technical change, and technical efficiency which all have been calculated by a Stochastic Frontier Analysis (SFA). The obtained results have been analyzed with respect to any institutional circumstances in a second analytical step. Based on that, in a third step, some political call for actions have been specified as well as addressed according to regional/federal responsibility. The study has shown a notable heterogeneity within the considered regional as well as sectoral transition paths....

Risk and De-Collectivisation: Evidence from the Czech Republic AgEcon
Bezemer, Dirk J..
The replacement of wage-labour farms by family farms in Central and Eastern Europe during the transformation has been more limited than was initially expected. In this paper a formal framework is developed in order to analyse the behaviour of family farms and socialist-style farms in the presence of risk, given the typical post-socialist environment. Management incentives, ownership structure, lump-sum transfers and consumption choices are shown to have the potential to limit the size of family farms relative to socialist-style farms. The hypotheses are tested with survey data collected by the author in the Czech Republic.

Reforms and Efficiency Change in Transition Agriculture AgEcon
Swinnen, Johan F.M.; Vranken, Liesbet.
Studies on efficiency changes in transition agriculture yield mixed results. This paper develops both a theoretical model and an empirical analysis of how distribution of efficiency scores changes with the various stages of transition. We use a unique set of representative farm survey data to calculate farm level efficiency scores, compare the efficiency distributions of different transition countries and correlate these with various indicators of particular reforms. Our study indicates that, in particular, general institutional reforms and reforms focused on market institutions and on reducing market imperfections in input and output markets have an important positive impact on farm efficiency.

BLUNT TO SHARPENED RAZOR: INCREMENTAL REFORM AND DISTORTIONS IN THE PRODUCT AND CAPITAL MARKETS IN CHINA AgEcon
Zhang, Xiaobo; Tan, Kong-Yam.
A key objective of China's reform program was to reduce distortions in the economic system and enhance growth. However, when implemented in incremental and partial ways, local governments or individuals have chance to capture rents inherent in the reform process. Young (2000) warned that the rent-seeking behavior might lead to increasing market fragmentation. Empirical studies have since shown that this did not happen in the product markets. In this paper we argue that as rents from the product markets were squeezed out during the reform process, rent-seeking behavior shifted to the factor markets, especially the capital and land markets. The reform process now needs to be deepened to ensure that the factor markets also become more integrated and efficient.

Investment Reluctance: Irreversibility or Imperfect Capital Markets? Evidence from German Farm Panel Data AgEcon
Huettel, Silke; Musshoff, Oliver; Odening, Martin.
Investment behavior at the firm level is characterized by lumpy adjustments and frequent periods of inactivity. Low investment rates are particularly puzzling in transition economies where an urgent need of modernization exists. The literature offers two explanations for. Firstly, neo-institutional finance theory focuses on the impacts of imperfect capital markets on investment decisions showing that the limited availability of financial funds may confine firms’ investments. Secondly, real options theory asserts that the interaction of irreversibility, uncertainty and flexibility may also result in investment reluctance. In this paper we suggest a generalized model that combines imperfect capital markets and real options effects. We also offer an...
