Rangeland Management During Drought: Assessing Social-Ecological And Cognitive Indicators Of Ranchers’ Adaptive Capacity, Tonya Haigh Oct 2019

Rangeland Management During Drought: Assessing Social-Ecological And Cognitive Indicators Of Ranchers’ Adaptive Capacity, Tonya Haigh

School of Natural Resources: Dissertations, Theses, and Student Research

Rangeland managers face challenges to adapt to climate extremes, and research is needed on how to support their adaptive capacity for managing climate risk. This study evaluates adaptive capacity using an integrated vulnerability and resilience conceptual model and three cognitive behavioral models. Overarching research questions focus on the relationship between protective action and impacts and the best predictors of taking action in response to drought. Three studies address these questions, using quantitative data collected from two post-drought surveys of rangeland-based livestock managers in the Northern Great Plains of the U.S. The studies find evidence of the roles of social-ecological sources …

Drought Impacts Assessment In Brazil - A Remote Sensing Approach, Denis Mariano Aug 2019

Drought Impacts Assessment In Brazil - A Remote Sensing Approach, Denis Mariano

School of Natural Resources: Dissertations, Theses, and Student Research

Climate extremes are becoming more frequent in Brazil; studies project an increase in drought occurrences in many regions of the country. In the south, drought events lead to crop yield losses affecting the value chain and, therefore, the local economy. In the northeast, extended periods of drought lead to potential land degradation, affecting the livelihood and hindering local development. In the southern Amazon, an area that experienced intense land use change (LUC) in the last, the impacts are even more complex, ranging from crop yield loss and forest resilience loss, affecting ecosystem health and putting a threat on the native …

Comparisons Of Drought Institutions Between The U.S. And Korea, Sungbyung Chae May 2019

Comparisons Of Drought Institutions Between The U.S. And Korea, Sungbyung Chae

Department of Environmental Studies: Undergraduate Student Theses

Drought occurs in basically dry area around the area of less precipitation but it affects all around the world that can occur anywhere there is a deficit of rainfall from expected levels. This happened by the extreme climate event over land lower precipitation over a period of months to years. This could affect agricultural systems around the world, within food, ecologically atmosphere condition and also the habitation food security. From the developing in the modern technology, since the environment of nature is the basic element of living creature, human would be facing the challenging of agriculture, forestry, fisheries and food …

In the United States, drought is the second costliest natural disaster, which leads to the need for increased drought mitigation efforts over time. However, drought planning has lagged behind other hazard mitigation efforts, which is likely due to the lack of a national drought planning policy. Although the Federal Emergency Management Agency (FEMA) requires all jurisdictions have a hazard mitigation plan (HMP) to receive pre-disaster mitigation funds, drought has only recently been a requirement in HMPs. In 2012, Nebraska witnessed its worse drought in recent history, which exposed the gaps in drought planning effectiveness at all jurisdictional levels. To address …
