Environmental media discourse analysis allows researchers to explore thematic patterns in media coverage of environmental issues through qualitative observations and quantitative coding. In this paper, we review newspaper media coverage in Florida pertaining to the connections between agriculture, other non-point pollution sources, and downstream ecosystem health. We analyzed 930 articles from 2007 through 2019 to determine common patterns in how these issues are covered by Florida media, including patterns in the causes of environmental problems, potential solutions, and stakeholders mentioned. Findings suggest that water quality problems are often framed as unpredictable or episodic rather than chronic, and as requiring (and only potentially being remediated by) state-level centralized technological or infrastructural solutions. Stakeholder relationships are framed as adversarial, with environmentalists and the agricultural sector as opponents. This case study highlights key power dynamics, barriers, and opportunities for better managing and communicating about agricultural land use practices and associated downstream environmental impacts.

Future changes in land use/land cover (LULC) and climate (CC) affect watershed hydrology. Despite past research on estimating such changes, studies on the impacts of both these nonstationary stressors on urban watersheds have been limited. Urban watersheds have several important details such as hydraulic infrastructure that call for fine-scale models to predict the impacts of LULC and CC on watershed hydrology. In this paper, a fine-scale hydrologic model—Personal Computer Storm Water Management Model (PCSWMM)—was applied to predict the individual and joint impacts of LULC changes and CC on surface runoff attributes (peak and volume) in 3800 urban subwatersheds in Midwest Florida. The subwatersheds a range of characteristics in terms of drainage area, surface imperviousness, ground slope and LULC distribution. The PCSWMM also represented several hydraulic structures (e.g., ponds and pipes) across the subwatersheds. We analyzed changes in the runoff attributes to determine which stressor is most responsible for the changes and what subwatersheds are mostly sensitive to such changes. Six 24-h design rainfall events (5- to 200-year recurrence intervals) were studied under historical (2010) and future (year 2070) climate and LULC. We evaluated the response of the subwatersheds in terms of runoff peak and volume to the design rainfall events using the PCSWMM. The results indicated that, overall, CC has a greater impact on the runoff attributes than LULC change. We also found that LULC and climate induced changes in runoff are generally more pronounced in greater recurrence intervals and subwatersheds with smaller drainage areas and milder slopes. However, no relationship was found between the changes in runoff and original subwatershed imperviousness; this can be due to the small increase in urban land cover projected for the study area. This research helps urban planners and floodplain managers identify the required strategies to protect urban watersheds against future LULC change and CC. [Display omitted] • Changes in runoff attributes due to CC and LULC change in 3800 urban watersheds. • Greater changes for runoff peak than volume. • Greater changes in both runoff attributes for milder slope and smaller watersheds. • Dominant impacts of CC over LULC change for both runoff attribute.

[Display omitted] • The trends of surface runoff and flood area changes were different. • Rainfall change is the dominant driver compared with land use change. • There are coupled effects from rainfall and land use changes on both surface runoff and flood area. • The easily flooded areas would experience negative coupled effects under future rainfall and land use conditions. • The areas with inadequate drainage and low elevation variation would be of high probability to suffer flooding issues. Future rainfall and land use are two important factors for flood management since they both directly and indirectly affect the functionality and performance of urban stormwater drainage infrastructures. Although some studies have already examined the coupled effects of future rainfall and land use conditions, they have not concluded how such effects on both surface runoff and flood areas would change with regional surface elevation variation and infrastructure conditions. This paper analyzed the coupled effects of future rainfall and land use on urban drainage systems in terms of surface runoff quantity and flood area changes using EPA SWMM. Future downscaled and bias-corrected precipitation projections for 2040–2060 and 2080–2099 from "Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections" Archive and future land use for 2050 s and 2090 s from EPA ICLUS project were used for the City of Tampa in Florida (USA). It was shown that potential runoff volume and flood area changes ranged from −40% to 160%, and −40% to 400% due to rainfall change, while potential changes induced by land use change ranged from 0% to 3.5%, and 0% to 18% respectively. Additionally, this study examined the coupled effects of future rainfall and land use changes on flood area variations, considering the capacity of drainage infrastructure and elevation variation of study site. Results showed that flood area variations are not solely influenced by runoff quantity changes due to the two external drivers, but also by other factors. Specifically, in low-relief areas with inadequate drainage infrastructure and less elevation variation, these two drivers have no additive effects on the percentage of flood area changes. In contrast, in areas with adequate drainage infrastructure and greater surface elevation variation, there are additive effects from rainfall and land use changes on flood area expansions. These findings have important implications for stakeholders involved in city planning and flooding control, particularly for urban areas facing future precipitation and urbanization challenges.

The state of Florida is renowned for its globally recognized biodiversity richness, but it currently suffers from an ongoing population boom and corresponding urban sprawl resulting in the emergence of severe conservation conflicts, especially in southern parts of Florida. To mitigate the intense competing land use situation and comprehend the dynamic complex relationship between conservation and development, this study argues that both ecological and social dimensions should be taken into account for spatial analysis and underpin zoning decisions empirically in the phase of landscape planning. Choosing South Florida as the study site, we implemented focal-species-based spatial conservation prioritization analysis using Zonation software to identify the highest priority areas and accordingly evaluate two varying land use scenarios provided by the Florida 2070 Project. From a novel perspective of impact avoidance, the inverse prioritization method was applied in this study, intended to minimize negative human impacts and examine the effectiveness and suitability of Florida's future land use projections. After comparing and integrating social-ecological data through mapping, the study uncovered a holistic view of conservation conflicts in Florida and articulated trade-offs for all parties of the local ecosystem striving to reconcile human–wildlife conflicts in Florida and imply a sustainable win-win strategy in the stage of regional landscape planning.

The Anastasia Mosquito Control District (AMCD) of St. Johns County (SJC), St. Augustine, Florida, USA, was formed in 1948 to cover the 27 km2 of Anastasia Island and control the black salt marsh mosquito, Aedes taeniorhynchus (Wiedemann). Today AMCD covers the entirety of SJC (1588 km2) and Ae. taeniorhynchus is still the most abundant mosquito species in the county. Here we present the findings from 16 years' worth of surveillance records of AMCD mosquito populations in conjunction with annual land-use land-cover (LULC) change and climate data to better understand how environmental factors have impacted SJC Ae. taeniorhynchus populations in recent history. The statistical regression and geospatial analyses demonstrated the presence of spatial and temporal clusters of Ae. taeniorhynchus populations in terms of abundance and distribution. Additionally, Ae. taeniorhynchus abundance and distribution were significantly influenced by the annual changes of LULC and climate variables. The linear regression analysis using standard least square and corrected Akaike Information Criterion revealed a migration of mangrove swamps and saltwater marshes that corresponded to a southern shift in the spatial–temporal distribution of Ae. taeniorhynchus communities. This was confirmed by the significant change in LULC characteristics between three representative years (2004, 2009, 2014) and the redistribution of Ae. taeniorhynchus abundances represented by Moran's I index values. The annual values of four climate variables (average and minimum temperature, mean dew point, and maximum vapor pressure deficit) and three LULC types (mangrove swamps, saltwater pools within saltmarshes, and upland nonforested) significantly predicted annual abundance and redistribution of Ae. taeniorhynchus.

Fenster, M.S.; Hughes, C.P., and Stutz, M.L., 2022. A survey of global mixed-energy and wave-dominated barrier island distribution and development. Journal of Coastal Research, 38(4), 795–806. Coconut Creek (Florida), ISSN 0749-0208. This study quantifies the length, percentage, and type of development found on global mixed-energy and wave-dominated coastal plain and deltaic barrier islands. Google Earth photographic imagery from 2015–2017 was used to measure the lengths of individual islands, identify infrastructure types 300 m landward of the shoreline, and measure the alongshore extent of each island's land uses. The United States Geological Survey's land-use classification scheme enabled categorization and quantification of predominant structure types. The results from this study showed that, of the 1444 mixed-energy and wave-dominated barrier islands located within 53 countries around the world: (1) 832 (approximately 59%) of those barriers islands have some type of development; (2) approximately 16% of the total length of shorelines (approximately 1,793 km/11,249 km) are developed; (3) wave-dominated barriers (approximately 17%) are more developed than mixed-energy (approximately 14%) barriers; (4) coastal plain (approximately 21%) settings have double the development than deltaic settings; (5) the U.S. contains approximately 66% of all developed global barrier island shorelines and the highest percent development of mixed-energy (New Jersey approximately 67%) and wave-dominated (Florida approximately 62%) coastal plain barrier islands in the world; and (6) high-density, residential dwellings dominate development type and comprise an average 14% of the world's barrier island shorelines. Finally, development percentage and/or land use type do not appear to depend on or correlate with hydrodynamic or geologic setting and coastal processes and geology do not influence development type. Instead, site specific or regional factors most likely dictate the percentage and type of development. [ABSTRACT FROM AUTHOR]

Land-use and land-cover (LULC) change is a primary driver of terrestrial carbon release, often through the conversion of forest into agriculture or expansion of urban areas. Classification schemes are a key component of landscape analyses. This study creates a novel LULC classification scheme by incorporating ecological data to redefine classes of an existing LULC classification based on variation in above-ground tree carbon. A tree inventory was conducted for 531 plots within a subbasin of the Tampa Bay Watershed, Florida, USA. Above-ground tree carbon was estimated using the i-Tree model. Plots were classified using the Florida Land Use Cover Classification System. Mean quantities of above-ground tree carbon, by class, were tested for statistical differences. A reclassification was conducted based on these differences. Sub-classes within a given "land cover" class were similar for six of the seven classes. Significant differences were found within the "Wetlands" class based on vegetation cover, forming two distinct groups: "Forested Wetlands" and "Non-forested and Mangrove Wetlands". The urban "land use" class showed differences between "Residential" and "Non-residential" sub-classes, forming two new classes. LULC classifications can sometimes aggregate areas perceived as similar that are in fact distinct regarding ecological variables. These aggregations can obscure the true variation in a parameter at the landscape scale. Therefore, a study's classification system should be designed to reflect landscape variation in the parameter(s) of interest. [ABSTRACT FROM AUTHOR]

Particulate matter (PM) recovery from street sweeping (SS), catch basin (CB), and unit operation (UO) is essential for sustainability of these urban hydrologic functional units (HFUs). PM inventory in HFUs is of increasing interest. PM granulometry and transformations thereof are needed to examine loads and export from HFUs. This study uniquely examines transformation of PM distributions recovered from SS, CB, and UO, representing serial HFUs coupled from up- to downstream in drainage systems. HFUs are also indexed to land uses (residential, highway, commercial) across Florida (n=470 samples). Results indicate the dominant PM mass is sand-size from 425 to 1,000 μm. Gravimetrically, particle size distributions (PSDs) are represented by a cumulative gamma distribution (CGD) (Radj2:0.98–0.99). Particle number density (PND) is represented by a power law model (PLM) with a log-log transformation (R2:0.86–0.89). Results indicate UOs (n=163) as a downstream HFU had PSDs that were less heterodisperse and finer than CB (n=155) and SS (n=152). PNDs are statistically consistent between SS, CB, and UO, given the transport of suspended PM from pavement through UOs, which cannot capture suspended PM. PM from SS is statistically more enriched in the suspended and sediment fractions than CBs and UOs due to export from these HFUs. Land use has been hypothesized as a factor impacting PSDs. However, results indicate that the impact of land use is not statistically significant for recovered PSDs. These findings are a useful resource of PM granulometry for urban PM residuals and facilitate implementation of more sustainable drainage systems. [ABSTRACT FROM AUTHOR]

No other form of property ownership is as synonymous with Florida as the condominium. While ownership of airspace was possible under common law, modern condominiums are more accurately described as creatures of statute. Although the Florida Condominium Act (FCA) expressly provides for fee simple airspace ownership of condominium property, it had been unclear if the Act could provide for fee simple airspace ownership of non-condominium property. Sterling Breeze v. New Sterling Resorts cleared up that ambiguity and found that the FCA can provide for fee simple ownership of non-condominium airspace. First, this note will review the development of airspace ownership rights as they relate to condominiums within both common law and statutory regimes. Next, this note will explain key provisions of the FCA as well as Florida case law relevant to airspace ownership. This note will then discuss Sterling Breeze v. New Sterling Resorts which tested whether, under the Florida Condominium Act, non-condominium airspace can be owned in fee simple if the non-condominium airspace was described in a condominium declaration. Adopting a contract-based approach that looks to condominium declarations governed by the FCA, the Sterling Breeze court affirmed that non-condominium airspace can be owned in fee simple if that airspace was described in the declaration creating the condominium. This note will then consider potential benefits of the contract-based approach to airspace ownership adopted in Sterling Breeze and briefly discuss the urban planning and land-use benefits that flow from including non-condominium airspace within the FCA's scope. This note concludes with a consideration of how Florida common law may also provide for fee simple airspace ownership outside of the Florida Condominium Act. [ABSTRACT FROM AUTHOR]
