AgEcon Search: Research in Agricultural and Applied Economics collects, indexes, and electronically distributes full text copies of scholarly research in the broadly defined field of agricultural economics including sub disciplines such as agribusiness, food supply, natural resource economics, environmental economics, policy issues, agricultural trade, and economic development.


The majority of items in AgEcon Search are working papers, conference papers, and journal articles, although other types such as books chapters and government documents are included. AgEcon Search will serve as the permanent archive for this literature and encourages authors and organizations to use this electronic library as the storehouse for additional appropriate scholarly electronic works.


AgEcon Search is co-sponsored by the Department of Applied Economics and the University Libraries at University of Minnesota and the Agricultural and Applied Economics Association.


The site has received encouragement and financial support from:


Agricultural Economics Reference Organization
Agricultural and Applied Economics Association
European Association of Agricultural Economists
Farm Foundation
International Association of Agricultural Economists
USDA Economic Research Service

History


AgEcon Search began in 1995 as an experiment to see if it were possible to use the internet to archive, index and deliver on demand, full text working papers produced by university agricultural economics departments. The first papers were from agricultural economics departments at Minnesota and Wisconsin. These early papers predated the World Wide Web and were mounted on a GOPHER server in WordPerfect format. The project was (and still is) a cooperative project of the University of Minnesota Libraries, the Department of Applied Economics at the University of Minnesota and the Agricultural and Applied Economics Association (AAEA). The Farm Foundation and the Economic Research Service of the U.S. Department of Agriculture provided financial support in the beginning of the project. Patricia Rodkewich and Louise Letnes managed AgEcon Search until Patricia's retirement in 2001, when Julie Kelly joined the AgEcon Search team. Erik Biever also served on the original AgEcon Search team, providing valued technical services and guidance. The members of the Agricultural Economics Reference Organization endorsed the efforts of AgEcon Search early on and have been instrumental in expanding the use of AgEcon Search in their respective institutions.


Since its inception AgEcon Search has operated as a distributed network, with each institution designating a member of their organization to submit papers on their behalf. With this model, costs for maintaining the system were kept low and institutions do not have to pay membership fees for participation. In the cases where an institution had no central person to act as the network member, a fee has been charged for AgEcon Search staff to submit papers. The first organization to choose this option was the Agricultural and Applied Economics Association, which since 1997 has been contracting with AgEcon Search to post its annual conference papers.

Rising oil prices has led to increased interest to replace domestic demand for liquid fuels for transport (petrol and diesel) with biofuel production (ethanol and biodiesel). One of the pioneers in biofuel production is Brazil, which since the 1970s has established a government program that promotes the production and consumption of ethanol. Currently, Brazil is the leading producer of ethanol in the world and has started also programs for biodiesel production based on soybeans, oil palm and other crops.

The lack of appropriate incentives through conventional markets is a major cause of deterioration of biodiversity on private land. In response, governments often intervene through changing the incentives faced by landholders. There are, however, potentially many ways that the incentives to private landholders could encourage improved conservation of native vegetation on private lands. These policies and incentives leverage change in different ways and are suited to differing opportunities and objectives and incur different costs.
