Australian And Us Experiences With Transfer Of Rangeland Improvement Technologies: A Comparative Analysis, A P. Thurow, N MacLeod, J R. Conner 2024 Texas A&M University

Australian And Us Experiences With Transfer Of Rangeland Improvement Technologies: A Comparative Analysis, A P. Thurow, N Macleod, J R. Conner

IGC Proceedings (1977-2023)

American and Australian range economists work in tandem with range ecologists and management specialists to develop and analyze strategies for technology transfer. Historically, this process has developed around a model aimed at communication with a narrow target group (ranchers) with easily-defined and homogeneous goals (continuously improving income). In accord with this traditional model of technology transfer, the focus of range economists’ inquiries was once to assess the cost-effectiveness of grazing improvement technologies (Conner, 1985). It is a relatively recent phenomenon that both American and Australian range technology transfer agents are encountering an increasingly broad social and ecological agenda. Ranchers recognize …

Farmer Participation In The Development And Implementation Of A New Technology: Introduction Of Lucerne (Medicago Sativa L.), A Perennial Legume, Into South-West Western Australia, L J. Blacklow, P Cocks 2024 Agriculture Western Australia

Farmer Participation In The Development And Implementation Of A New Technology: Introduction Of Lucerne (Medicago Sativa L.), A Perennial Legume, Into South-West Western Australia, L J. Blacklow, P Cocks

IGC Proceedings (1977-2023)

Australia since its demise due to insect attack in the 1970s. With new insect resistant varieties lucerne is once again becoming a viable pasture option for farmers. There is however, a slow rate of adoption of lucerne for a number of social and economic factors. The main limitations to the adoption of lucerne by farmers are past negative experience, farm systems dominated by annual pastures, changing wool and wheat commodity prices and perceived establishment and management difficulties. To overcome these socio-economic limitations a Model of Lucerne Adoption was developed in which the target group for the technology, the farmer, took …


Case Studies- A Useful Tool For Integrating Socio-Economic Data Into Grazing Systems Research, N D. MacLeod 2024 CSIRO

Case Studies- A Useful Tool For Integrating Socio-Economic Data Into Grazing Systems Research, N D. Macleod

IGC Proceedings (1977-2023)

Grazing systems research and development (R&D) projects can provide important information on which to base management principles to integrate conservation management into grazing production systems. However, the adoption of these principles into practice remains largely unfulfilled. Most grazing experiments give limited attention to the socio-economic context of pastoral management. The paper suggests that one way of incorporating R&D findings and presenting them within a context that is more acceptable to decision-makers is via a case study approach. That is, use the considerable communication potential of the approach.


The Punctuated Arena Model- A New Approach To Tackling Technology Transfer Failure, N D. MacLeod, A D. Shulman 2024 CSIRO

The Punctuated Arena Model- A New Approach To Tackling Technology Transfer Failure, N D. Macleod, A D. Shulman

IGC Proceedings (1977-2023)

Valuation of the worth of research and development activities is increasingly shifting from outputs to outcomes. The technology transfer record of agricultural R&D focused on pastures and resource management remains generally poor. Participatory R&D approaches have been developed and promoted to overcome this, but these also have performance problems. Based on the authors’ experience with R&D and communication management a Punctuated Arena Model has been developed which is argued to offer scope for improving technology transfer outcomes.

Agri-21: Sustainable Farming Demonstration, M Rasnake, W R. Burris, G D. Lacefield

IGC Proceedings (1977-2023)

On-farm demonstrations were established in 1993 to demonstrate the technology required to conduct a profitable and sustainable farming operation into the 21st Century. These were part of a cooperative program between the Tennessee Valley Authority (TVA) and Land Grant Universities in the seven states of the TVA region. Four demonstrations were established in Kentucky. A beef farm in west Kentucky will be used to illustrate the project. This farm improved crop and livestock management, record keeping and environmental stewardship. Their goal is to increase farm profitability while improving the soil and water resources.


Extension Agronomist Perceptions Regarding Clover Use In The Usa, D M. Ball, G D. Lacefield 2024 Auburn University

Extension Agronomist Perceptions Regarding Clover Use In The Usa, D M. Ball, G D. Lacefield

IGC Proceedings (1977-2023)

Recent enhancement of economic incentives for using legumes in forage/livestock systems seems likely to result in greater usage of clovers in the USA. To determine attitudes regarding clovers, a questionnaire was sent to forage crop agronomists having Extension assignments. Responses to most questions varied greatly, particularly among geographic regions. Poor grazing management was identified as the primary concern or problem associated with clovers, followed by poor persistence, and a lack of recognition of the benefits. Improved forage quality was ranked as the most important benefit, followed by better distribution of pasture growth, and biological nitrogen fixation. The importance of benefits …


Roles Of Clovers In Southeast U.S.A Pastures, G D. Lacefield, D M. Ball, J C. Henning, M Rasnake 2024 University of Kentucky

Roles Of Clovers In Southeast U.S.A Pastures, G D. Lacefield, D M. Ball, J C. Henning, M Rasnake

IGC Proceedings (1977-2023)

Grasses dominate pastures in the Southeast U.S.A.; research and farmer experience have shown that the addition of legumes to grass dominant pastures can improve environmental, agronomic and animal parameters. Legumes grown in mixtures with grasses can increase yield, improve forage quality and animal performance, convert atmospheric nitrogen into a form useable by plants, extend the grazing season, and offset certain animal disorders. As livestock producers continue to strive for more sustainable feed production and utilization programs with greater emphasis on grazing, legumes will play an even greater role in Southeast U.S.A. agriculture.

Sustainable Grazing Systems- A Program To Develop And Deliver Improved Temperate Pastures In Australia, W K. Mason, G Kay, G Lodge

IGC Proceedings (1977-2023)

The Sustainable Grazing Systems Program aims to combine the efforts of producers, researchers and extension agents into a focused partnership to develop, manage and implement grazing systems that are more profitable and more sustainable. Rather than the traditional approach of undertaking the research and then developing extension packages for livestock producers, this Program has set up a network with producers, researchers and extension agents to collectively develop and test improved systems. The process is described as colearning. Compared with more traditional approaches, producer input is greatly increased as the role of researchers and extension agents is modified, but not decreased. …

Land Evaluation For Sustainable Land Use By Remote Sensing And Gis Case Study: Assessment Of Soil Erosion In Pakistan, Y Yamamoto, S Uchida, T Suyama, A Shoji

IGC Proceedings (1977-2023)

In the northern part of Punjab in Pakistan, severe soil erosion has caused land degradation and has disturbed sustainable land use systems. Since much of this erosion has been marked near rivers, watersheds and topography are considered to be related to soil erosion. We applied the Geographic Information System (GIS) and Remote Sensing to the assessment of an erodible area. GIS is very useful for conducting spatial data analysis using map data. Remotely sensed data provides the information about land surfaces. In this study, the distance from the river, weighted by the slope estimated by GIS, and the standard deviations …
