About

Dr. Edward 'Gilly' Evans is a professor in the Food and Resource Economics Department at the University of Florida, located at the Tropical Research and Education Center (TREC) in Homestead. He holds a Ph.D. in food and resource economics from the University of Florida, with specialization in agricultural policy analysis, international trade, and development. His previous research focused on theoretical and empirical analyses of international trade policy rules and institutions such as GATT, WTO, NAFTA, and LOME. His current research emphasizes applied agricultural trade policy analysis and environmental sustainability of agriculture. Most of his research is conducted as a member of interdisciplinary teams of scientists at TREC, aimed at generating economically viable and environmentally friendly technologies, practices, and production and marketing systems. His work includes generating knowledge to conserve and improve water quality at the watershed level, developing economically viable preventative integrated pest management vegetable production systems, implementing efficient fertilizer management, and exploring the economic feasibility of developing biodiesel from Jatropha and ethanol from sweet potatoes. He also investigates the economics of managing invasive species (foreign pests and diseases) in tropical and sub-tropical areas of the United States.

• MEDICAL ETHICS AND FACILITATING FULLY INFORMED CONSENT TO TREATMENT

  2024-04-24

  preprintOpen access

  It has been asserted that there was an erosion of medical ethics during the Covid-19 pandemic and a departure from the principle of obtaining fully informed consent from patients before treatment. In light of these assertions, this article reviews the historical development of medical ethics and the approach to obtaining informed consent, and critiques the consent practices before and during the pandemic. It then describes a new tool for displaying key statistics on the benefits and risks of interventions to help explain them to patients and suggests a more rigorous process for seeking fully informed consent in the future.

• Estimación de costos para la producción de guayaba rosada (Psidium guajava L.) en el sur de Florida

  EDIS · 2022-02-08

  articleOpen access1st authorCorresponding

  Guava is planted thorugh the Tropics and SubTropics and has adapted to a variety of climatic conditions. Florida is the primary producer of guava in the United States. This crop is valued at $3.2 million at the packing house. The growing interest in alternative tropical crops in the last few years has led to increasing interest in this crop. This publication estimates the costs and returns from an established guava orchard in south Florida. We estimate that an established pink guava orchard will have a net return of $9065 per acre per year or $1.13 per pound of fruit sold.

• Consumer Preferences for Green Skin Avocados in the US Market: The Role of Experienced Quality Attributes, Credence Attributes, and Demographic Factors

  Abstract The purpose of this paper is to assess the effect of experienced quality attributes, credence quality attributes and demographic factors affecting green-skin avocado consumption. Data for the present study came from a consumer online survey to 355 avocado consumers. Consumer preferences were modeled by an ordered logit model. Results indicate that experienced quality attributes are the main drivers for green-skin avocado followed by origin and health credence attributes, respectively. Demographic factors other than ethnicity do not play a significant role for green-skin avocado consumption. Among other things, the findings indicate that consumers place a higher valuation on higher fat content compared to low calorie content, implying that the latter attribute should not be touted at the expense of the former. To the extent possible, the industry should focus on cultivars with higher fat content and develop promotional activities to target non-Hispanic consumers. The present study constitutes an effort to contribute to the existing literature as it explores the role of health credence attributes, a topic that has not received much attention.

• Recomendaciones para la Detección y Mitigación de la Marchitez del Laurel en Árboles de Aguacates y Especies Relacionadas en Jardines y Patios Hogareños

  EDIS · 2020-09-30

  articleOpen access

  This is the Spanish translation of HS1358, Recommendations for the Detection and Mitigation of Laurel Wilt Disease in Avocado and Related Tree Species in the Home Landscape. Avocado trees are a popular choice for homeowners in Florida, with over 600,000 growing in Florida home landscapes. However, avocado trees as well as others in the Lauraceae family are susceptible to laurel wilt disease, which can kill a tree in as few as three weeks. This new 8-page publication of the UF/IFAS Horticultural Sciences Department provides home owners recommendations for identifying and mitigating laurel wilt disease in the home landscape. Written by Jonathan H. Crane, Jeff Wasielewski, Daniel Carrillo, Romina Gazis, Bruce Schaffer, Fredy Ballen, and Edwards Evans.https://edis.ifas.ufl.edu/hs1384

• Recommendations for Control and Mitigation of Laurel Wilt and Ambrosia Beetle Vectors in Commercial Avocado Groves in Florida

  EDIS · 2020 · 16 citations

  • Horticulture
  • Biology
  • Forestry

  The lethal laurel wilt epidemic affecting avocado trees in Florida is caused by a fungal pathogen-ambrosia beetle complex (LW-AB). The death of over 120,000 commercial avocado trees in Florida may be attributed to LW-AB. Recommendations for control and mitigation of this epidemic are needed to guide commercial producers in their decision-making process. This new 8-page publication of the UF/IFAS Horticultural Sciences Department outlines the LW-AB epidemic, provides information on the pathogen and ambrosia beetle vectors, provides a brief outline of current research findings, and offers recommendations for the control and mitigation of LW-AB. Written by Jonathan H. Crane, Daniel Carrillo, Edward A. Evans, Romina Gazis, Bruce Schaffer, Fredy Ballen, and Jeff Wasielewski. Correction as of 3/30/2020: Under "Prophylactic Fungicide Injections," this document previously said that when using Tilt, growers needed to have in their possession a Section 18 special local needs label (SLN). This has been corrected to read that they need a Section 18 Emergency Exemption label.

• Planning for a Successful Commercial Subtropical/Tropical Fruit Grove

  EDIS · 2020-11-09 · 2 citations

  articleOpen access

  Planning is the key to successful grove establishment, maintenance, and production. Developing a detailed infrastructure description and plan, cultural program, and financial and marketing plan for a new or existing grove with a new fruit crop will save you time and money and help minimize mistakes. Prospective growers should compile and analyze information needed to select a grove site, establish the needed infrastructure, and develop maintenance plans for the plants and how the production will be marketed. This new 15-page publication of the UF/IFAS Horticultural Sciences Department presents an outline of the type of information growers need when establishing a tropical fruit grove or contemplating management or modification of an existing grove.
