Decision Analytical Methods For Robust Water Infrastructure Planning Under Deep Uncertainty, Mehmet Umit Taner

Doctoral Dissertations

Deep uncertainties resulting from climate change, demographic pressures, and rapidly evolving socioeconomic conditions are challenging the way that water planners design and operate large-scale infrastructure systems. Conventionally, water infrastructures have been developed using stationary methods, assuming that the underlying uncertainties can be derived from historical data or experience. However, these methods are less useful under deeply uncertain climate and socioeconomic conditions, in which the future can be substantially different from the past and cannot be expressed by well-defined probability distributions. The recognition of deep uncertainties in long-term water resources planning has led to the development of “decision-analytical” frameworks that do …

New York City 2050: Climate Change And Future Of New York | Design For Resilience, Abhinav Bhargava

Masters Theses

The escalating temperature, annual precipitation, sea level rise and carbon footprint will likely lead to an unimagined future which does not have a bright side. With the rise in carbon footprint particularly due to greenhouse gas emissions, burning of fossil fuels and change in land uses; carbon dioxide is 40% higher as compared to era before Industrial Revolution.

The constant increase in temperature is melting the glaciers and increasing the sea levels. The Hudson River is estimated to rise by 1.5-2ft by 2050, directly affecting the low-lying areas of Staten Island, Brooklyn, Queens and Manhattan. Amongst the multiple coastal cities …

The Effects Of Anthropogenic Stress On Nitrogen-Cycling Microbial Communities In Temperate And Tropical Soils, George S. Hamaoui Jr.

Doctoral Dissertations

In this dissertation several research studies are discussed that characterize the effects of anthropogenic, or human-induced, stress on both ammonia-oxidizing and total bacterial soil microbial communities. The disturbances of land-use change in tropical, South American rainforests and artificial warming and nitrogen (N) fertilization in temperate, North American forests were investigated as these disturbances represent past and current disturbances caused by human landscape alteration and climate change. Initially, the response of soil ammonia-oxidizing microbial communities to land-use change from primary rainforest to pasture and, finally, back to secondary forest was determined. Next, these analyses of land-use change effects were expanded to …

Methods For Incorporating Ecological Impacts With Climate Uncertainty To Support Robust Flood Management Decision-Making, Caitlin M. Spence

Doctoral Dissertations

Modern and historic flood risk management involves accommodating multiple sources of sources of uncertainty and potential impacts across a broad range of interrelated sectors. Sources of uncertainty that affect planning include internal climate variability, anthropogenic changes such as land use and system performance expectations, and more recently changes in climatology that affect the resources supporting the system. Flood management systems potentially impact human settlements within and beyond the systems’ scope of planning, local weather patterns, and associated ecological systems. Federal guidelines across nations have called for greater consideration of uncertainty and impacts of water resources planning projects, but methods for …

The Perfect Storm: Lasting Impacts Of Structural Adjustment Programs And Pressures Of Climate Change In Latin America And Ghana, Africa, Sam Kefferstan

Student Showcase

This work examines the intersectionality of economic, social and environmental impacts of the International Monetary Fund’s and World Bank’s application of structural adjustment programs (SAPs) within Latin America and Ghana, Africa. Varying economic and social indicators illustrate the underperformance of SAPs in their intended mission to reduce poverty and debt in developing nations. This research argues Gross Domestic Product is an imperfect measure of improving quality of life and points towards other indicators such as increasing national debt, rising incidences of poverty, and exacerbated regional disparities to demonstrate the shortcomings of SAPs. This piece also investigates the limitations adjustment imposes …
