An Assessment Of The Effects Of Desertification In Yobe State, Nigeria, Jibril Musa Phd
Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria
Desertification is one of the most serious environmental and socio-economic problems of our time. Desertification describes circumstances of land degradation in arid, semi-arid and dry sub-humid regions resulting from the climatic variation and human activities. The fundamental goal of this thesis was to assess the effects of desertification in Yobe State, Nigeria. The present threat of desertification in the sahel has reached an alarming stage where crops cultivation and animal rearing/grazing are no more productive, soil has lost its nutrient/fertility, various infrastructure had given way because of windstorm from the neighbouring Niger Republic and sand dunes had taken over. The …

Lagoons are highly productive coastal features that provide a range of natural services that society values. Their setting within the coastal landscape leaves them especially vulnerable to profound physical, ecological, and associated societal disturbance from global climate change. Expected shifts in physical and ecological characteristics range from changes in flushing regime, freshwater inputs, and water chemistry to complete inundation and loss and the concomitant loss of natural and human communities. Therefore, managing coastal lagoons in the context of global climate change is critical. Although management approaches will vary depending on local conditions and cultural norms, all management scenarios will need …

Information Content Of Seasonal Forecasts In A Changing Climate, Nir Krakauer, Michael D. Grossberg, Irina Gladkova, Hannah Aizenman
Publications and Research
We study the potential value to stakeholders of probabilistic long-term forecasts, as quantified by the mean information gain of the forecast compared to climatology. We use as a case study the USA Climate Prediction Center (CPC) forecasts of 3-month temperature and precipitation anomalies made at 0.5-month lead time since 1995. Mean information gain was positive but low (about 2% and 0.5% of the maximum possible for temperature and precipitation forecasts, resp.) and has not increased over time. Information-based skill scores showed similar patterns to other, non-information-based, skill scores commonly used for evaluating seasonal forecasts but tended to be smaller, suggesting …

Prevalence And Economic Value Of Feral Swine Damage To Native Habitat In Three Florida State Parks, Richard M. Engeman, Henry T. Smith, Stephanie A. Shwiff, Bernice Constantin, John Woolard, Mark Nelson, Daniel Griffin
Associate Professor Mark Nelson
Feral swine (Sus scrofa) adversely affect the environment in many of the places where they have been introduced. Such is the case in Florida, but quantification and economic evaluation of the damage can provide objective bases for developing strategies to protect habitats. Swine damage to native wet pine-flatwoods at three state parks in Florida was monitored from winter 2002 to winter 2003. Economic valuations of damage were based on the US dollar amounts that wetland regulators have allowed permit applicants to spend in attempts to replace lost resources. The parks had different swine management histories and the damage …

Bioeconomic Analysis Of Herpetofauna Road-Kills In A Florida State Park, Stephanie A. Shwiff, Henry T. Smith, Richard M. Engeman, Robert M. Barry, Robin J. Rossmanith, Mark Nelson
Associate Professor Mark Nelson
Road-kills are a major cause of mortality for a wide variety of herpetofauna, but management decisions on remediation procedures for reducing losses are based in economic realities. Because funding is finite for species conservation, bioeconomic analysis can assist in justifying, evaluating, and maximizing returns on conservation expenditures, especially for low-profile species such as herpetofauna. Here, we present a bioeconomic analysis of road-killed herpetofauna in Jonathan Dickinson State Park, Florida. Road surveys were conducted daily for four years to identify and enumerate the numbers of each reptile and amphibian species killed by vehicles. Conservative individual valuations applied to the losses formed …

Monitoring Changes In Feral Swine Abundance And Spatial Distribution, Richard M. Engeman, Bernice Constantine, Mark Nelson, John Woolard, Jean Bourassa
Associate Professor Mark Nelson
Swine (Sus scrofa) have been introduced in many places throughout the world, and in many places they adversely affect the environment, economically impact agriculture, and/or harbor diseases transmittable to domestic livestock or humans. An easily applied method to assess their abundance is an important need for their management. To monitor efficacy of a swine control program in Florida, data from passive tracking plots provide an index of feral swine abundance. The same track data coupled with plot locations to numerically describe the spatial pattern of swine activity gave an index of pervasiveness, and a simple rate of interception of damage …
Geomorphologic Evolution Of A Rapidly Deteriorating Barrier Island System With Multiple Sediment Sources: Eastern Isles Dernieres, Louisiana, 1887 To 2006, Benjamin T. Kirkland
Geomorphologic Evolution Of A Rapidly Deteriorating Barrier Island System With Multiple Sediment Sources: Eastern Isles Dernieres, Louisiana, 1887 To 2006, Benjamin T. Kirkland
University of New Orleans Theses and Dissertations
Trinity, East, and Wine Islands make up the eastern half of the Isles Dernieres barrier arc in south-central Louisiana. Formed following the abandonment of the Lafourche delta complex, subsidence and storm erosion have led to rapid deterioration of the system. Since 1887, the land area of the islands has decreased seventy-seven percent, and the gulf shoreline has retreated landward more than a kilometer. Wave ravinement on the shoreface of the islands is responsible for the most sediment loss; liberated sediment travels longshore to tidal inlets. The dominant ebb tidal currents then transport the sediment to where it is deposited in …

Evaluating The Uncertainty Of The Population Growth Parameter Estimates Of Larval Anchovy In The Southwestern Waters Of Taiwan Using Monte Carlo Simulations, Sheng-Ping Wang, Ming-An Lee, Wen-Yu Chen
Journal of Marine Science and Technology
To estimate the population growth parameter (maximum sustainable yield, carrying capacity, catchability, the ratio of initial biomass to carrying capacity and model shape parameter) of larval anchovy in the southwestern waters of Taiwan, a non-equilibrium production model was used to fit to historical catch data and standardized CPUE series. The results of standardized CPUE indicated that the sea surface temperature was the most effective variable for explaining the CPUE variation of larval anchovy abundance. This study also evaluated impact of the uncertainty associated with the catch and CPUE data on the model estimations using Monte Carlo simulations. Although the impacts …

Assessing The Feasibility Of Small Hydropower In Northern California, Andrea Peterson
Masters Theses, 2010-2019
Small hydropower is an underutilized form of clean energy generation. In order for any potential for small hydropower to be developed or utilized, the amount of potential power needs to be estimated accurately. A number of studies have been conducted, though none of these studies have taken local climate into account, which affects the accuracy of their results. A number of places in Northern California have potential that has not yet been utilized, but a more accurate assessment of that potential is called for. Although studies can be conducted through a number of different methodologies, most use GIS technology to …

Quantification Of Carbon Emission Reduction By U-Transportation Service Effect: A Case Study Of Dongtan U-City, Tae-Woong Jung, Mu-Wook Pyeon, Jee-Hee Koo
Journal of Marine Science and Technology
With the emergence of the response to climate change as a global agenda, UNFCCC member countries must report their Greenhouse Gas (GHG) emissions and absorptions. With conventional carbon emission estimation methods such as the IPCC Guideline, however, it is impossible to measure reduction of carbon emissions by U-City services. Therefore, this study proposed estimating carbon emission reductions by using U-transportation services as a model because this service appears to be the most effective among U-City services in terms of carbon emission reduction. This approach which is unique in Korea has also attempted to quantify the reduction of carbon emissions by …

Landslides are natural phenomena for the dynamic balance of the earth's surface. Because of frequent occurrences of typhoons and earthquakes in Taiwan, mass movements are common threats to people's lives. In this paper, the interpretation of knowledge is quantified as recognition criteria. Multisource high-resolution data, for example, a SPOT satellite image, 20 m × 20 m Digital Terrain Model (DTM) reduced from Light Detection And Ranging (LiDAR) data, and aerial orthophotos were used to construct the feature space for landslide analysis. Landslides were recognized by an objectoriented method combining edge-based segmentation and a Supported Vector Machine (SVM) method. The classification …
Rainwater Utilization To Reduce Flooding In Low-Lying Areas Of Taipei City, Taiwan, Andrew Lo
Rainwater Utilization To Reduce Flooding In Low-Lying Areas Of Taipei City, Taiwan, Andrew Lo
Journal of Marine Science and Technology
She-Zih is a low-lying area in Taipei City where the Tanshui River and Keelung River meet. Average elevation is about 2.5 m. Perennial flood events occur very often. The only flood prevention facility is the 6 m levee built around the perimeter to overcome 20-yr flood events. The main cause of the flooding problem is the instantaneous extreme high rainfall events that often exceed the drainage capacity of She-Zih. Current solutions to relieve this water hazard, suggested by the Water Resources Agency, include channel widening and many water pumping installations. At present, all emergency facilities are insufficient to combat unexpected …

According to data from the Ministry of Agriculture, Forestry, and Fishes of Japan, Tohoku accounted for 27.59% of Japan’s rice yield in 2010. It is an impact to a country that relies on rice as its main food source. This paper utilizes remote sensing techniques to estimate the disaster losses in rice field and yield in Fukushima and Miyagi, the most severely damaged coastal prefectures of the Tohoku region, by using a developed Rice field Identification and riCe …
Quantataive Analysis Of Relationship Between Alos Palsar Backscatter And Forest Stand Volume, Choen Kim
Quantataive Analysis Of Relationship Between Alos Palsar Backscatter And Forest Stand Volume, Choen Kim
Journal of Marine Science and Technology
To estimate forest stand volume, topographic effects should be considered in Synthetic Aperture Radar (SAR) data processing, because most forests are located on mountainous areas in Korea. This paper shows how the effects on the ALOS Phased-Array L-Band SAR (PALSAR) backscatter in Kwangneung Experiment Forest can be reduced by gammanought γ 0 . Regardless of coniferous and deciduous forests, the gammanought γ 0 values are always lower compared to the sigmanought σ0 values at HH and HV polarization for 58 standwise tree volume of the fore-slope (here, the west-facing slope) and are always higher in case of far-slope (here, east-facing …
