Assessing Sustainability: Some Conceptual and Empirical Challenges AgEcon
Toman, Michael; Lile, Ronald D.; King, Dennis M..
In this paper we address two related conceptual and practical challenges in assessing "sustainability." The first is the criteria to be used, in particular the relationship between sustainability and measures of economic well-being and the use of monetary versus nonmonetary indicators. The second is the problem of determining which physical scales to use for sustainability assessments when there are multiple and overlapping "communities" or stakeholder groups. While neither set of challenges admits a definitive solution, there has been progress on the first set of issues - in particular, through the development of multicriteria assessment strategies and stakeholder involvement processes. In contrast, the problem of how to assess sustainability in practice...

Dynamics of Spatial Exploitation: A Metapopulation Approach AgEcon
Sanchirico, James N.; Wilen, James E..
We present a bioeconomic model of a harvesting industry operating over a heterogeneous environment comprised of discrete biological populations interconnected by dispersal processes. The model generalizes the H. S. Gordon [1954]/V. Smith [1968] model of open-access rent dissipation by accounting for intertemporal and spatial "Ricardian" patterns of exploitation. This model yields a simple, but insightful, framework from which one can investigate factors that contribute to the evolution of resource exploitation patterns over space and time. For example, we find that exploitation patterns are driven by biological and fleet dispersal and biological and economic heterogeneity. We conclude that one cannot really understand the biological processes operating in...

Evaluating the implementation process of LEADER in Romania AgEcon
Marquardt, Doris; Mollers, Judith.
LEADER supports integrated rural regional development. The programme is characterized by a participatory and bottom-up approach, public-private partnerships, multi-sectoral regional development strategies and innovation. An obligatory Common Monitoring and Evaluation Framework (CMEF) was set up for evaluating EU interventions. The CMEF builds upon sets of common indicators and evaluation questions. Romania, where LEADER is currently introduced, has set national priorities for the programme implementation. For assessing the impact of LEADER in Romania meaningfully, an extension of the CMEF is needed. This paper, identifies and suggests appropriate indicators. Social Network Analysis is proposed as a tool for investigating intangible outcomes of LEADER in a...

Farm Household Income and On-and-Off Farm Diversification AgEcon
McNamara, Kevin T.; Weiss, Christoph R..
The paper analyzes the relationship between off-farm labor allocation and on-farm enterprise diversification as farm household income stabilization strategies with census data from the federal state of Upper Austria, Austria. The results suggest that both on-farm diversification and off-farm labor allocation are related to farm and household characteristics. Larger farm households tend to allocate more labor to off-farm income activities.
