Extreme droughts like the recent 2011–2013 drought impacting the central and western United States present a challenge to sustaining livestock ranching operations and the ecosystem goods and services they produce. Wyoming ranchers manage half of this drought-prone state and are at the forefront of this challenge. We examined Wyoming ranchers’ drought management strategies and how ranch characte...

The concept of the return period is widely used in the analysis of the risk of extreme events and in engineering design. For example, a levee can be designed to protect against the 100-year flood, the flood which on average occurs once in 100 years. Use of the return period typically assumes that the probability of occurrence of an extreme event in the current or any future year is the same. Ho...

The purpose of this study was to examine the impacts of Climate Change on Agricultural Production and to propose measures and initiatives on behalf of the European Parliament in the framework of the European Union Agricultural Policy. This study was carried out by a group of experts who collected information on the project, from relevant sources. Furthermore, we would like to thank Mr Marcelo S...

Rainfall is an essential index to measure drought, and it is dependent upon various parameters including geographical environment, air temperature and pressure. The nonlinear nature of climatic variables leads to problems such as poor accuracy and instability in traditional forecasting methods. In this paper, the combined forecasting method based on data mining technology and cross entropy is p...

Climate change modelers predict increasingly frequent "extreme events," so it is critical to quantify whether organismal responses (such as reproductive output) measured over the range of usual climatic conditions can predict responses under more extreme conditions. In a 20-year field study on water pythons (Liasis fuscus), we quantified the effects of climatically driven annual variation in fo...

Intermittent rivers and ephemeral streams (IRES), those watercourses that periodically cease to flow or dry, are the world's most widespread type of river ecosystem. Our understanding natural hydrology ecology IRES has greatly improved, but their responses extreme events such as drought remain a research frontier. In this review, we present state art, knowledge gaps directions on droughts in fr...

After extreme events such as floods, thunderstorms, blizzards and hurricanes there will be devastating effects in the distribution networks which may cause a partial or complete blackout. Then, the major concern for the system operators is to restore the maximum critical loads as soon as possible by available generation units.  In order to solve this problem, this paper provides a restoration s...
