Mitigating risk of weather variability to agriculture through improved field workability predictions
Evolving weather-related risks, driven by climate change, will impose challenges on agricultural production systems at a global scale. However, the spatial heterogeneity of cropping practices, current climate, projected climate changes, and environmental factors (such as soil) will influence these …

Marine weather variability, tropical cyclone prediction and impacts in the Southwest Indian Ocean
… by significant inter-annual climate variability and numerous tropical cyclones. Long-and short-term variability and associated oceanic and atmospheric fields are analyzed using model-assimilated data. The evolution of monsoon circulations associated with composite tropical cyclones …

Vulnerability of horticulture producers to climate variability and change : the case of Chókwe District, Mozambique
… livelihood; however, this district is prone to weather variability and climate stresses, affecting the region's agricultural performance and making farmers' livelihood even more precarious. There is indeed limited information on this vulnerability, how farmers cope with the risks as well as …

Early Wildfire Detection with Line Sensors
… in western U.S., severe drought conditions and weather variability cause residents to become more vulnerable to wildfire disasters as their safety is threatened. We are incompetent to control the wildfires effectively despite existing advanced technologies. Hence, an algorithm based on energy …

The role of statistical distributions in vulnerability to poverty analysis
… on rainfed agricultural activities, extreme weather events such as droughts can present existential challenges to their livelihoods. To mitigate these risks, numerous social protection programs have been established to assist vulnerable households affected by weather events. Despite efforts …

Climate change adaptation measures in agriculture : a case of conservation agriculture for small-scale farmers in Kalomo District of Zambia
… limited capacity to adapt to extreme climate variability, thus rendering them to be among the most vulnerable to climate change. Some recent studies show that agricultural production and productivity is being negatively impacted by climate change and variability in most parts of Southern …

When the Waters Came
… dollars later. As climate change exacerbates weather variability and storm severity, areas like the Midwest are expected to see more, and worse, floods and other disasters. Agriculture is crucial to the region’s economic success and residents’ livelihoods, so it will be increasingly important …

A Dynamic Decision Support System for Drought Resiliency and Climate Change
… supplying water to its customers, regardless of weather patterns and water supply. Simply put, there is no room for a shortage under any conditions. This can be most challenging in times of drought, when available water is slim and the utility system is most stressed. Across the west, these …

Analysis of the dynamics of government-supported smallholder baby vegetable enterprises for an integrated high-value development framework
… cash inflows affect liquidity of farms, while weather variability and unavailability of labour during harvesting induced crop losses that undermined farmers’ economic returns. Growers use non-saving financial services and have unsatisfactory financial literacy that led to poor financial …

Variable weather and implications for herbicide efficacy and yield loss due to weeds
… to worsen throughout the 21st century. Variable weather impacts crops, weeds, and their management; however, empirical study of these phenomena has been piecemeal and limited to a handful of site years (e.g. generally 2 to 4). This research was developed to shed light on how future climate …

On the observed and simulated responses of the extratropical atmosphere to surface thermal forcing
… large-scale and local patterns of climate and weather variability from one region of the globe to another. Improvements in the resolution of satellite observations and numerical models over the past decade have led to a series of advances in understanding the role of the ocean in extratropical …

Essays on international economics
… and how we utilize short-run variations in weather to recover estimates of the severity of these frictions. We then use these estimated frictions to estimate the effects of new long-term productivity distributions, both over time and across space, on variables of interest. In Chapter 2, we …
