Despite this, some chemical treatments have been effective. For example, methyl anthranilate, a common food additive, is used as a biodegradable non-toxic bird repellant for grapes and berries. One study showed a decrease in crop loss by 88% to 99% when crops were treated with methyl anthranilate . However, in another study, methyl anthranilate was …

We also evaluate the impact of using different amounts of training data and calibration durations
Measuring and predicting temperature accurately is challenging due to variation across farm micro-climates where local temperature can deviate from the surrounding area which is typically measured at mesoscale. Measuring temperature for a large number of micro-climates on a farm can be prohibitively expensive with extant weather stations and sensors . In this chapter, we explore …
Plants were carefully harvested and transported in dry ice to the laboratory
Community Supported Agriculture appeals to an increasing number of people. In recent decades, CSA farm and member numbers have grown rapidly in the United States and in California’s Central Valley and foothills. CSA numbers in our study area grew from a few in the early 1990s to 74 in 2010. The loss of 28 CSAs found …

Non-CNN approaches have also been used to map irrigated and rainfed agriculture
My goal is to determine whether Mask R-CNN and FCIS produce substantially different results when applied to the task of segmenting center pivots, and if these differences are as pronounced as their performance on segmentation tasks in true color photography. This can inform the field of remote sensing on the value of adopting new CNN …

The emphasis has been on empirical analysis of listorical phenomena
Some argue that a major historical strength of agricultural economics has been its tolerance for a range of methodological approaches. Early agricultural economists drew on production agriculture, accounting and business, classical, neoclassical, and institutional economics. Some have even argued that the very parochialism and fragmentation of agricultural economics have been the basis for many of …

Extension workers are often expected to cover large areas with limited staff
Although farmers’ trust and understanding surely influences demand for weather index insurance, resolving these concerns has not proven sufficient to solve the demand issues that beset this financial product. Demand for insurance does increase when farmers observe payouts over time ; receiving payouts in the previous year has a strong effect on increasing subsequent demand, increasing …

We measured the child’s height and weight at the time that spirometry was performed
Ultimately, addressing the question of population-level effects will likely depend on a combination of measured field data, incorporating new methodologies for assessing survival to adulthood , and fish population models.Our observations must be considered within the constraints of the infrastructure in the Yolo Bypass during the time of our field work. In the intervening years …
Several studies have documented the benefits of direct markets to small-scale farmers
The rising temperature will severely reduce the snow pack in the Sierra Nevada, which currently provides almost as much storage at the beginning of the irrigation season as the state’s man-made reservoirs. By the end of the century, the spring snow pack is projected to decline by 30-70% under the B1 scenario, and by 70-90% under …
It is critical that San Diego leverage these advanced scientific tools to further maximize existing and developing programs
Reducing barriers and streamlining viability of opportunities are key factors in advancing sustainable agricultural practices. Economic incentives and supportive programs, at both the state and local levels, are key components to encouraging farmers to engage with these practices. Given that the average age of farmers in the region is 62 , we need to do …
NBA-P ensures that urgent tasks are prioritized subject to both energy and resource budgets
In precision agriculture, overhead imagery can help pinpoint locations that appear to be under water stress, in which case sampling leaves or soil in those areas should be prioritized. We formalize the notion of tasks with distinct urgency by assigning a priority level to tasks. Besides the task priority level, deciding a next task for a robot to …
