Abstract:
In many megacities of the developing world the combination of rapid population growth and demand for land results in people settling in areas prone to natural hazards. Dhaka, Bangladesh and Colombo, Sri Lanka are no exceptions. This thesis discusses the challenges faced as a result of seal level rise and increased flooding, and solutions realized in urban areas of low and middle-income nations. It attempts to find solutions to reduce the vulnerability of these communities in context to housing and infrastructure. These regions contain a third of the world’s population, and in addition to

Abstract:
This dissertation examines the concept of social vulnerability through documenting the intersection of both political-economic uncertainty and climatic variability in the production decisions and livelihood strategies of peasant farm households in three communities in central Mexico. Although the research is situated within the broader literature on globalization and climatic change, the study focuses on the impacts of the El Nino-Southern Oscillation events of 1997, 1998 and 1999 and the neoliberal agricultural policy reforms of the 1990s as rough analogies of these larger-scale processes.

Abstract:
Climate change while associated with change a in the mean climate also presents itself as a change in the variance of climate, resulting in an increase in the number of extreme climatic events (ECEs). Increased numbers of hot days, droughts and extreme precipitation events are all predicted under future climate scenarios. To date, there is very little understanding as to the potential effects that this may have on biodiversity. In order to model the future impacts of ECEs on biodiversity and to inform conservationists about the most appropriate mitigation strategies, we need to understand how

Climate change and extreme weather events are affecting the environment, and people’s livelihood in both developing and developed countries. Agriculture, forestry, fishing, livestock, water resources, human health, terrestrial ecosystems, biodiversity, and coastal zones are among the major sectors impacted by these shocks. The challenge of adaptation is particularly acute in the developing countries, as poverty and resource constraints limit their capacity to act. Bangladesh fits in this category, and thus I use data from Bangladesh to analyze the adaptation process in the first and second cha

Forest fires are an increasing concern under climate change. Substantially increased fire vulnerability could become a reality for many areas, including the Rocky Mountains.

Ensemble climate scenarios were chosen to represent a wide range of possible future climates. The GENGRID meteorological model and the Canadian Forest Fire Weather index System were combined to assess possible changes in forest fire hazard in the Rocky Mountains.

Abstract:
Water management plans are typically developed using historical data records and historical return periods for extreme events, such as floods or droughts. Since these analyses of return periods typically assume a certain degree of stationarity (constant mean, standard deviation, distribution) in hydrologic variables, the potential future impacts of climate change are excluded. In developing water management plans, predicted changes to climate variables should be considered to evaluate the degree of non-stationarity that may exist in the future. In this way, regions most sensitive to climate ch
