  Citation × Citation Citation Abstract Copy Title: Assessing landscape complexity using remotely sensed and field based measurements : does landscape complexity drive leafroller parasitism rates on Oregon caneberry farms? Author: Winfield, Tammy L. Landscape heterogeneity is thought to differ among farm management types (i.e. organic and conventional), and this difference is hypothesized to result in variations in pest control by natural enemies. However, it is unclear if these variations in pest control are driven by landscape structure or by farm management practices themselves. Remotely sensed datasets were used to describe the landscape structure surrounding a group of organic and conventional caneberry farms in Oregon and Washington that have different leafroller parasitism rates attributed to farm management type. A finer scale survey was done at one of the farms using the remotely sensed data as well as field surveys. Landscape metrics of diversity, richness and percent non-crop were used to describe the landscapes surrounding the farm fields at scales ranging from 0.05 km to 5.00 km for the large scale study, and 0.05 km to 0.20 km for the fine scale study. In the fine scale study, data on parasitoid species assemblages, diversity, and parasitism rate were collected and analyzed against the calculated landscape metrics spatially and seasonally. The purpose of this study was to quantify effects of farm management type on habitat structure, effect of habitat structure on leafroller parasitism rate, and to access correlations between landscape metrics calculated at the landscape and field scale. Overall, the farms were embedded in a landscape that was broadly similar, with very few differences in landscape structure occurring between organic and conventional farms. Organic farms had higher vegetation height class diversity at the largest scale compared to conventional farms, while conventional farms had significantly higher percent non-crop area compared to organic farms. There was no significant effect of any of the calculated landscape metrics on parasitism rates. In the field scale study, no correlations were found between habitat metrics and parasitism rates, or between field based metrics and those calculated at the landscape scale. The results of this study suggest that conventional and organic caneberry farms in the Willamette Valley are broadly similar in the habitat conditions they provide parasitoids. This suggests that management changes to pesticide use alone could increase levels of leafroller biological control on conventional farms to levels that are comparable to those seen on organic farms. Our comparisons of the landscape scale and field scale landscape metrics showed no connection, this suggests that direct comparisons cannot be made with these particular metrics at these very different scales. Rather than comparing these types of data, it may be more useful to combine them in order to increase the resolution and predictive power of remotely sensed data for describing landscapes at broad scales.

  Citation × Citation Citation Abstract Copy Title: Whole farm case studies : a how-to guide Author: Murray, Helene Calls for increased farmer involvement in research and extension programs have been numerous and well supported. One approach to integrate the collective knowledge and experience of agricultural scientists and farmers is through whole farm case studies (WFCS). An interdisciplinary team of 34 research and extension personnel at Oregon and Washington State Universities conducted WFCS of 16 vegetable and small fruit farms beginning in April 1989. The objectives of the Oregon/Washington case study project were to: (1) increase farmer involvement in research and education programs; (2) develop an interdisciplinary team to address issues of agricultural sustainability in western Oregon and Washington; (3) examine the use of the case study approach in agricultural situations; (4) prepare a guide to assist other persons interested in conducting WFCS; (5) develop a better understanding of vegetable and small fruit farming systems in the region; and, (6) identify sustainable agriculture research and education needs in western Oregon and Washington. The WFCS process proved useful in developing an interdisciplinary team, and the vast majority of team members participating in the study stated they would consider using the WFCS approach again in their work. However, the primary constraint cited by all team members was the amount of time required to conduct the study. The process of conducting WFCS in western Oregon and Washington improved communication among a wide group of people. Team members gained a better understanding of the complexity of farms and identified several areas requiring further research. Farmers stated they enjoyed participating in the case study project and discovered new information that will assist them in managing their farming systems. Farmer-developed innovations were identified that are useful to other farmers and to the research process. Included in this thesis are: (1) a guide for conducting whole farm case studies; (2) a summary of data collected from 16 farms in western Oregon and Washington participating in the WFCS, including a summary of interaction among interdisciplinary team members; and, (3) a profile of one of the farms participating in the WFCS.

  Citation × Citation Citation Abstract Copy Title: Farm-Level Efficiency and Resource-Productivity: Application of Stochastic Frontier Analysis to Aquaculture Farms in the South-West Nigeria Author: Ogundari, Kolawole This paper comparatively examined resource-use and technical (TE) efficiencies of aquaculture farms in the Southwest Nigeria. A total of 160 farms were randomly selected from four states across the region. Econometric applications of the stochastic frontier models provide measure of the farm’s technical efficiency. The results of regressions specified for the farms in each states, show that, elasticites for inputs, such as: size of the pond, feeds, labour, numbers of fingerling stocked, and costs of materials were positive and significant. This suggests that, the production functions monotonically increased with input from the study. The returns to scale estimates show that, an average farm in the states like, Ogun and Ondo exhibit increasing returns to scale, while similar numbers of farms in Osun and Ekiti states exhibit decreasing returns to scale. The results of marginal value product (MVP) show that, none of the farms across the states optimally used their variable inputs (MVPx =MFCx). Most farms were found to have underused (MVPx >MFCx) feeds and numbers of fingerlings stocked, as against overused (MVPx <MFCx) of labour across the states. The estimated TE shows that, about 11%, 18%, 22% and 44% of outputs of the farms in Ogun, Ondo, Ekiti and Osun states are forgone due to inefficiency respectively. The implications of these findings, therefore, suggest that improvement in the technical efficiency of the farms, as well as, optimal input utilization, will contribute significantly to aquaculture expansion program in the county.
