Última Computing Opportunity Costs of Growing Local Varieties for On-farm Conservation: Illustrations Using Sorghum Data from Ethiopia AgEcon Wale, Edilegnaw; Mburu, John G.; Estrella, Jaime. The recent shift of emphasis to on-farm conservation is driven by its diverse attractive features - participatory nature, dynamic nature, capacity to maintain not only crop diversity but the knowledge that evolves with it, the chance it offers and the challenge it brings to link conservation with farmers' livelihood. To make it operational, placing incentives and removal of perverse incentives are of critical importance. However, before placing sound incentives compatible to farmers' circumstances, the opportunity costs farmers face when using local varieties of public interest should be understood. This paper empirically examines farmers' opportunity costs of maintaining local varieties of sorghum using a household survey data collected from 198 sorghum...

Ano: 2006 URL: http://purl.umn.edu/25675 INTERNATIONAL EXCHANGE OF GENETIC RESOURCES, THE ROLE OF INFORMATION AND IMPLICATIONS FOR OWNERSHIP: THE CASE OF THE U.S. NATIONAL PLANT GERMPLASM SYSTEM AgEcon Day-Rubenstein, Kelly A.; Smale, Melinda. Changing perceptions of resource ownership have altered international exchange of genetic resources. After summarizing the role of genebanks and issues related to property regimes, this paper presents an empirical study of one of the largest national genebanks, the U.S. National Germplasm System. The demand for its genetic resources appears to be substantial, both domestically and internationally. Utilization rates are higher than suggested by past studies. The role of information in enhancing the usefulness of NPGS resources is explored with an econometric model that indicates that accompanying data make germplasm more useful. U.S. requestors account for most of the germplasm demanded, but developing countries appear to make greater use of these...

Ano: 2005 SUSTAINABLE USE AND MANAGEMENT OF CROP GENETIC RESOURCES: LANDRACES ON HUNGARIAN SMALL FARMS AgEcon Birol, Ekin; Smale, Melinda; Gyovai, Agnes. Crop genetic resources are natural assets that are necessary for future crop improvement. In isolated, marginal production environments where markets function imperfectly, farm families depend on them directly for food. In recognition of their importance, international agreements such as the Convention on Biological Diversity and the International Treaty on Plant Genetic Resources for Food and Agriculture encourage national governments to support their sustainable use and management, on farms and in gene bank collections. Hungary is a signatory to these international agreements. The aim of this study is to contribute research-based information to support the design of efficient and equitable conservation programmes for socially valuable crop landraces...

Ano: 2005 URL: http://purl.umn.edu/31935 THE DEMAND FOR CROP GENETIC RESOURCES: INTERNATIONAL USE OF THE U.S. NATIONAL PLANT GERMPLASM SYSTEM AgEcon Smale, Melinda; Day-Rubenstein, Kelly A.; Zohrabian, Armineh; Hodgkin, T.. In contrast to a perception that ex situ collections of germplasm are rarely used, this empirical case study reveals large quantities of germplasm samples distributed by the U.S. National Germplasm System to many types of scientific institutions located in numerous countries around the world. Distributions favor developing countries in several ways including the numbers of samples shipped, utilization rates in crop breeding programs, and the secondary benefits brought about through sharing this germplasm with other scientists. Expected future demand is also greater among scientists in developing countries. These findings underscore the importance to global science and technology of retaining such resources in the public domain.

Ano: 2001 URL: http://purl.umn.edu/16086 The Origin, Development And Structure Of Demand For Plant Genetic Resources. The Impact Of The In Trust Agreements To The CGIAR Collections Availability AgEcon Caracciolo, Francesco; Gotor, Elisabetta; Holloway, Garth J.; Watts, Jamie. The objective of this paper is to explore how the demand of germplasm held by CGIAR genebanks changed over time in order to assess the possible influence of the 1994 In Trust Agreements on germplasm demand. The proposed theoretic model motivates the realistic hypothesis that the consequences of the In-Trust Agreements lead to an enhancement of CGIAR germplasm utilization. Therefore the paper firstly examines the classical literature on biodiversity’s valuation and its recent developments and subsequently it investigates the origin of the agricultural biodiversity’s economic value, providing a basic conceptual framework to infer on factors determining the demand for germplasm. Two Bayesian estimation frameworks are applied to the IRRI accessions...
