world population has already exceeded 6.5 billion, out of which about 850 million (13 percent) are undernourished. with the current growth rate, the world community faces even a greater challenge of hunger and food security as the estimated the population will catch 9 billion by the year 2050 with doubled needs for food. at the same time, preservation of biodiversity, stopping deforestation and...

Economic impact analysis (EIA) of outdoor recreation can provide critical social information concerning the utilization of natural resources. Outdoor recreation and other non-consumptive uses of resources are viewed as environmentally friendly alternatives to extractive-type industries. While outdoor recreation can be an appropriate use of resources, it generates both beneficial and adverse soc...

Estimates of the global economic impacts of observed climate change during the 20th century obtained by applying five impact functions of different integrated assessment models (IAMs) are separated into their main natural and anthropogenic components. The estimates of the costs that can be attributed to natural variability factors and to the anthropogenic intervention with the climate system in...

Energy production in the United States is in transition as the demand for clean and domestic power increases. Wind energy offers the benefit of reduced emissions, yet, like oil and natural gas, it also contributes to energy sprawl. We used a diverse set of indicators to quantify the ecological impacts of oil, natural gas, and wind energy development in Colorado and Wyoming. Aerial imagery was s...

Habitat loss is the greatest threat to biodiversity and rapid, human-forced climate change is likely to exacerbate this. Here we present the first global assessment of current and potential future impacts on biodiversity of a habitat loss and fragmentation–climate change (HLF–CC) interaction. A recent meta-analysis demonstrated that the negative impacts of habitat loss and fragmentation have be...

Accurate measures of human effects on landscape processes require consideration of both the direct impacts from human activities and the indirect consequences of the interactions between humans and the landscape. This is particularly evident in systems experiencing regular natural disturbances such as in the mountainous areas of southwestern China, where the remaining population of giant pandas...

Software changes are difficult since the impacts of the changes are not readily known in advance. For safety-critical system, the changes can even introduce hazards to bug down the system. Then impact analysis makes its way into the software process. It identifies the consequences or ripple-effects of proposed software changes. In impact analysis, identifying the change impacts is a central act...

Rear-end impacts caused worse initial symptoms and specific clinical findings, not clearly distinguished from those occurring after frontal impacts. WAD III injuries, retro-orbital pain, and isolated contra-directional pro-/retraction pain occurred more frequently after rear-end impacts, indicating the importance of shear loads and craniocervical junction vulnerability. Head inward rotation dur...
