This study develops a dynamic bioeconomic model using the Bellman equation to derive the optimal management strategy for Witches’ Broom Disease of Lime (WBDL) and the optimal replanting age of citrus trees after the first attack under multiple scenarios of disease management options and climate conditions. In addition, the study investigates different scenarios of disease presence and spread given different climatic conditions of arid, semi-arid and tropical zones in Oman. Factors such as disease incidence, severity, spread, and specific climatic conditions of three growing regions are considered. The farmers' optimal disease mitigation decision is determined by the disease density and insect vector level on the farm, and adverse climate conditions have a significant negative impact on the economic value of citrus cultivation. Results indicate that management measures by citrus growers and policymakers should be based on the climatic conditions of the growing region with a high level of treatment frequency and intensity in the arid region, and lime production should be concentrated in the tropical and semi-arid regions of the country.

This publication, Part 1 in the Florida Marine Baitfish Aquaculture series, outlines opportunities and challenges associated with marketing aquacultured live marine baitfish in Florida. It examines why Florida is uniquely suited for the continued development of this industry, reviews the marine recreational angling baitfish market, and describes the opportunities and challenges associated with marine baitfish marketing and selling live baitfish to marine baitfish retailers. This publication is intended to provide information to current and potential farmers, as well as management agency and outreach personnel and the interested public. It should help farmers, potential farmers, and perhaps investors understand the potential scale, opportunities, and challenges of live baitfish aquaculture in Florida. This same information can assist policymakers and outreach personnel in their management decisions and the communications of those decisions.

This article is a part of the EDIS series “Economic Value of Florida Water Resources” (see https://edis.ifas.ufl.edu/topic_series_valuing_florida_water_resources ). This series is aimed at helping water-resource professionals and interested citizens improve their knowledge of the economic value of goods and services provided by Florida water resources. The focus of this paper is specifically on supporting and regulating ecosystem services provided by Florida water resources.

This paper is a part of the EDIS series “Economic Value of Florida Water Resources” and it presents results from economic studies examining benefits from water-based recreation in Florida. Our special focus is freshwater-based recreation. Specifically, studies examining the “economic contribution” or “economic impact” of recreation activities around various natural sites are discussed. Interested reader can pick and choose the studies most relevant to his/her area of interests or those discussing recreational sites nearby. https://edis.ifas.ufl.edu/fe1065

This paper is a part of the EDIS series “Economic Value of Florida Water Resources”. As the other papers in the series discuss, water resources provide us with a variety of goods and services (often referred to as ecosystem services). This paper discusses another ecosystem service that Florida water resources provide: water supply for households needs. In this article, we present several examples of valuing water availability found in literature and focused on Florida and other regions.

This 9-page fact sheet written by Tatiana Borisova, Xiang Bi, Tara Wade, and Kurt Oehlbeck and published by the UF/IFAS Food and Resource Economics Department explores the relationship between water quality and sale prices of waterfront properties, that is, the amenity value provided by water resources to waterfront communities. Being near to water to water generally increases the value of a residential property. However, poor water quality may decrease waterfront property prices. In other words, investments in restoring water quality can translate into increases in property value and tax collection. https://edis.ifas.ufl.edu/fe1062 This paper is a part of a series “Economic Value of Florida Water Resources”.

Florida water-resource professionals deciding whether to implement a costly water protection program or to invest in better tap water treatment technology may wonder: Are such investments justified? What are the benefits of the program or investment decision? Just how highly do Floridians value their water? This 5-page fact sheet written by Tatiana Borisova, Syed Irfan Ali Shah, Tara Wade, Xiang Bi, and Kelly Grogan and published by the UF/IFAS Food and Resource Economics Department reviews studies that help assess the value Floridians assign to maintaining or improving the quality of the water supply. http://edis.ifas.ufl.edu/fe1059

Water resources provide us with a variety of goods and services (altogether often referred to as ecosystem services or environmental services.) Part of a series entitled Economic Value of Florida Water Resources, this 5-page fact sheet written by Tatiana Borisova, Syed Irfan Ali Shah, Tara Wade, Kelly Grogan, and Xiang Bi and published by the UF/IFAS Food and Resource Economics Department assesses the economic value of the ecosystem services provided by irrigation water and shows the importance to agriculture of water resource protection and restoration. http:edis.ifas.ufl.edu/fe1057

Several economic factors should be considered in selecting an agricultural irrigation system. This 7-page fact sheet compares two widely used irrigation systems for tomato production: seepage and sub-surface drip irrigation. Written by Jenna Rogers, Tatiana Borisova, Jeffrey Ullman, Kelly Morgan, Lincoln Zotarelli, and Kelly Grogan, and published by the UF Department of Food and Resource Economics, October 2014.

The goal of this 11-page fact sheet is to help producers and other interested parties understand how alternative irrigation systems can affect economic outcomes in agricultural operations. We used chipping potato production in the Hastings area in northeast Florida as an example to discuss factors to consider when selecting an irrigation system.
