A gender performance indicator for irrigation: Concepts, tools and applications AgEcon
van Koppen, Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

A hedonic approach to estimating the supply of variety attributes of a subsistence crop AgEcon
Edmeades, Svetlana.
The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of...

A ÓTICA DA ECONOMIA DOS CUSTOS DA TRANSAÇÃO NO PROCESSO DE TOMADA DE DECISÃO EM CADEIAS PRODUTIVAS AGROINDUSTRIAIS: UMA PROPOSTA DE ESTRUTURA ANALÍTICA AgEcon
Dutra, Alberto Silva; Rathmann, Regis.
Teve-se como objetivo neste artigo abordar elementos teóricos já estudados sobre o processo de decisão, bem como da Economia dos Custos de Transação e da Análise Sistêmica, de forma a propor uma estrutura analítica sistêmica, multinível e interdisciplinar, que possa ser usada para o estudo da tomada de decisão de investimentos em cadeias produtivas agronegociais. Da consolidação do referencial teórico, por meio de estrutura analítica, aplicada a um estudo de caso, no caso a cadeia produtiva do biodiesel, pode-se perceber que na medida em que a commodity soja vai avançando nos elos da cadeia, vai se tornando um produto de maior valor agregado, cujos ativos envolvidos para seu processamento e distribuição possuem alta especificidade, o que por sua vez vai...

A systemic framework for context-based decision making in natural resource management: reflections on an integrative assessment of water and livelihood security outcomes following policy reform in South Africa Ecology and Society
Pollard, Sharon; The Association for Water and Rural Development; sharon@award.org.za; Biggs, Harry; SANParks; Harry.Biggs@sanparks.org; Du Toit, Derick R; The Association for Water and Rural Development; derick@award.org.za.
We aimed to contribute to the field of natural resource management (NRM) by introducing an alternative systemic context-based framework for planning, research, and decision making, which we expressed practically in the development of a decision-making “tool” or method. This holistic framework was developed in the process of studying a specific catchment area, i.e., the Sand River Catchment, but we have proposed that it can be generalized to studying the complexities of other catchment areas. Using the lens of systemic resilience to think about dynamic and complex environments differently, we have reflected on the development of a systemic framework for understanding water and livelihood security under transformation in postapartheid...

Agricultural Decision Analysis: The Causal Challenge AgEcon
Parton, Kevin A..
The paper sets out the agenda for reviewing models of decision making in the context of farmers’ use of seasonal climate forecasting. Such forecasts have been framed in terms of shifts in cumulative distribution functions of yields or gross margins. Typically they have been applied to choices about crop variety, crop type, time of planting or level of fertiliser application. Fundamental questions are: how do farmers conceptualise and make use of the information contained in seasonal climate forecasts? Do our models of decision making represent well the way in which these decisions are made?

Analysis of Farm Development in Dutch Agriculture and Horticulture AgEcon
Bremmer, Johan; Oude Lansink, Alfons G.J.M.; Olson, Kent D.; Baltussen, Willy H.M.; Huirne, Ruud B.M..
This paper analysis the effects of farmer characteristics, farm structure and farm performance on farm renewal and farm growth. The data set used in this research consists of panel data from the Dutch Farm Accountancy Data Network of farms specialized in plant production extended with a data from survey among those farms. Probit models were used to determine the likelihood of the changes. Results show that the degree of mechanization increases the probability of farm growth and farm renewal. Family labour input and solvency have a negative impact on farm growth. Farm size is positively correlated with farm renewal. No indications of the influence of the life cycle have been found.

Capturing Uncertainties in Evaluation of Biofuels Feedstocks: A Multi-Criteria Approach for the US AgEcon
Ziolkowska, Jadwiga; Simon, Leo K.; Zilberman, David.
Current research evaluating biofuels policies focuses primarily on market-economic criteria. While it is widely acknowledged that both the economic and environmental, and social aspects of biofuels policy must all be balanced with each other in the process of developing a viable biofuels policy, little progress has been made to date on evaluating these uncertain non-market relationships. In this paper, we develop a fuzzy theory holistic approach evaluating the 1st, 2nd, and 3rd generation biofuels feedstocks in meeting multiple economic, environmental and social criteria of the biofuels policies and capturing the uncertainties of evaluation processes. We use a multi-criteria approach PROMETHEE (Preference Ranking Organization Method for Enrichment...

Climate change and its associated consequences pose an increasing risk to public lands in the western United States. High-level mandates currently require federal agencies to begin planning for adaptation, but the extent to which these mandates have resulted in policies being implemented that affect on the ground practices is unclear. To examine the status of adaptation efforts, we conducted an original survey and semistructured interviews with land managers from the four major federal land management agencies in the U.S. states of Colorado, Utah, and Wyoming. The survey was designed to examine current planning for adaptation on public lands and how it differs from prior planning, the major challenges facing land managers in this region, the major...

Ecological assessments and monitoring programs often rely on indicators to evaluate environmental conditions. Such indicators are frequently developed by scientists, expressed in technical language, and target aspects of the environment that scientists consider useful. Yet setting environmental policy priorities and making environmental decisions requires both effective communication of environmental information to decision makers and consideration of what members of the public value about ecosystems. However, the complexity of ecological issues, and the ways in which they are often communicated, make it difficult for these parties to fully engage such a dialogue. This paper describes our efforts to develop a process for translating the indicators of...

Default and Inference Options: Use in Recurrent and Ordinary Risk Decisions AgEcon
Wilson, James D..
How "default options" should be used in health risk assessment divides the risk analysis profession. Some argue that these should be "hard": set by policy, generally biased to be "health protective" and requiring a substantial body of evidence to replace by decision-specific alternatives. Others argue that they should be science-based, identified by consensus of the professional community, replaced by whatever decision-specific information may be available to the analyst. This paper shows that both positions have validity, and that both are incomplete. Each kind of construct has a useful role to play, but in different kinds of decisions. Because the two are different, we suggest giving them different names, "default option" being assigned to the...

Developing decision-making tools for improving pasture quality on deer farms in New Zealand AgEcon
Stevens, David R.; Woodward, Simon J.R.; Westbrooke, Victoria F.C..
This paper describes the development of a learning package to support improved pasture quality on New Zealand deer farms. The first step has been to determine the specific requirements of deer farmers that will enable them to improve pasture quality decisions on-farm. Decision support software that interprets and demonstrates the impacts of pasture quality and animal physiology on the performance of young growing deer has also been developed. Key themes identified to aid pasture management decision-making included identifying the right pasture quality, management systems to maintain pasture quality and maximising the potential of livestock. This paper reports on the type of knowledge that deer farmers require in the learning package.
