Modelling The Encroachment Of Farmhouse Culture On Private Village Pastures And Its Environmental Fall-Out In Northern Western Ghats, India, S. B. Nalavade, K. R. Sahasrabuddhe, A. A. Patwardhan

IGC Proceedings (1997-2023)

Tropical India harbours numerous pasturelands across small landholdings ranging up to few hectares which are covered with grass that is suitable as fodder. These grazing lands are commonly known as ‘Gairan’ in urbanised northern Western Ghats mountain tract in Western India). Such grasslands comprise about 20% of the total area of a village (Jodha, 1986), support livestock and supplement the agro-economy of the village. These pasturelands are being replaced by fenced ‘farmhouses’ of the urban elite, resulting in land use changes that caused drastic qualitative and quantitative changes in terms of area, fodder species composition and livestock they …

Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski

Theses and Dissertations (Comprehensive)

The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …

Extreme Development Of Dragon Fruit Agriculture With Nighttime Lighting In Southern Vietnam, Shenyue Jia, Son V. Nghiem, Seung-Hee Kim, Laura Krauser, Andrea E. Gaughan, Forest R. Stevens, Menas Kafatos, Khanh D. Ngo

Institute for ECHO Faculty Books and Book Chapters

Dragon fruit is widely grown in Southeast Asia and other tropical or subtropical regions. As a high-value cash crop ideal for exportation, dragon fruit cultivation has boomed during the past decade in southern Vietnam. Light supplementing during the winter months using artificial lighting sources is a widely adopted cultivation technique to boost productivity in the major dragon fruit planting regions of Vietnam. The application of electric lighting at night leads to a significant increase of nighttime light (NTL) observable by satellite sensors. The strong seasonality signal of NTL in dragon fruit cultivation enables identifying dragon fruit plantations using NTL images. …

Impact Of Urbanization Trends On Production Of Key Staple Crops, José F. Andrade, Kenneth G. Cassman, Juan I. Rattalino Edreira, Fahmuddin Agus, Abdullahi Bala, Nanyan Deng, Patricio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Urbanization has appropriated millions of hectares of cropland, and this trend will persist as cities continue to expand. We estimate the impact of this conversion as the amount of land needed elsewhere to give the same yield potential as determined by differences in climate and soil properties. Robust spatial upscaling techniques, well-validated crop simulation models, and soil, climate, and cropping system databases are employed with a focus on populous countries with high rates of land conversion. We find that converted cropland is 30–40% more productive than new cropland, which means that projection of food production potential must account for expected …

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …

Urbanization—The Bad, The Good, And The Very Good, Rebecca Dolan

Rebecca W. Dolan

Great strides have been made in studying effects of urbanization on plant life in recent years. However, much remains to be learned about how the urban environment acts as a filter on flora. There is some evidence that environments in cities are so similar that they all select for the same plants or plants with the same suite of characteristics, resulting in biotic homogenization, but the jury is still out. We do know that some cities harbor a thriving and diverse native flora. Dolan will talk about what cities can do to increase the chances for long-term survival of native …

Influence Of Exurban Neighborhoods On Riparian Vegetation And Stream Salamanders In The Southern Appalachian Mountains, Nathaniel Weaver

All Theses

The southern Appalachian Mountains have experienced large population growth and a change in land use in the past 30 years. The majority of development has been low density, suburban land, known as exurban development. Lotic Systems and riparian areas are severely degraded by conversion from urban to rural land uses. The long-term effects of exurbanization on riparian vegetative communities and stream salamanders in the southern Appalachian Mountains are not well known. We sought to determine if vegetative community composition and structure change with time since neighborhood development or with the amount of impervious surface within the watershed. In order to …

Ecosystem Services Of Urban Trees And The Impacts Of Urbanization, Jorge E. Cantu

Theses and Dissertations - UTB/UTPA

The University of Texas- Pan American has conducted a complete survey of campus trees in partial fulfillment of the requirements for membership in the International Society of Arboriculture Designation of Tree Campus USA. This tree inventory was accomplished with the help of students whom were trained by faculty and foresters. Other than the completion of the tree inventory, this thesis had two main goals; 1) valuate the ecosystem services provided by campus trees 2) create a unique service learning project that other institutions can model. According to our calculations, the trees on campus have sequestered 568,652 kg of CO2, avoided …

Beta Diversity Of Urban Floras Among European And Non-European Cities, Frank A. La Sorte, Myla F.J. Aronson, Nicholas S.G. Williams, Laura Celesti-Grapow, Sarel Cilliers, Bruce D. Clarkson, Rebecca W. Dolan, Andrew Hipp, Stefan Klotz, Ingolf Kühn, Pter Pyšek, Stefan Siebert, Marten Winter

Rebecca W. Dolan

Aim- Cities represent an ideal study system for assessing how intensive land-use change and biotic interchange have altered beta diversity at broad geographic extents. Here we test the hypothesis that floras in cities located in disparate regions of the globe are being homogenized by species classified as invasive (naturalized species that have spread over a large area) or as a European archaeophyte (species introduced into Europe before ad 1500 from the Mediterranean Basin). We also test the prediction that the global influences of European activities (colonization, agriculture, commerce) have supported this outcome. Location- One hundred and ten cities world-wide. Methods- …

Urbanization contributes to the loss of the world's biodiversity and the homogenization of its biota. However, comparative studies of urban biodiversity leading to robust generalities of the status and drivers of biodiversity in cities at the global scale are lacking. Here, we compiled the largest global dataset to date of two diverse taxa in cities: birds (54 cities) and plants (110 cities). We found that the majority of urban bird and plant species are native in the world's cities. Few plants and birds are cosmopolitan, the most common beingColumba livia and Poa annua. The density of bird and plant species …

Bulletin No. 369 - Impact Of Urbanization In Davis County, Utah, Therel R. Black, Carmen D. Frederickson, William A. Dehart, C. Jay Skidmore, Don C. Carter

UAES Bulletins

This study of Davis County should assist community leaders to understand some areas of change and possible effects of changes in an urbanizing area and to understand possible sources of friction and cooperation. It should help residents of any urbanizing area to understand personal adjustments that may be necessary. Such understanding is needed by Utah's residents because Utah is becoming urban-in fact, approximately two-thirds of her population was urban in 1950. A brief summary of the study of Utah's fastest growing county shows the following changes during the 1940-1950 decade.
