Seasonally dry forests in the neotropics are heavily threatened by a combination of human disturbances and climate change; however, the severity of these threats is seldom contrasted. This study aims to quantify and compare the effects of deforestation and climate change on the natural spatial ranges of 17 characteristic tree species of southern Ecuador dry deciduous forests, which are heavily ...

Watershed modeling applications for the Fox and Iroquois River watersheds in Illinois were used to evaluate the response in simulated streamflow to various climate scenarios. The climate scenarios applied to both watersheds are based on simulations from two global climate models, the Japan and Hadley models, which respectively represent comparatively “dry” and “wet” scenarios of future climatic...

Dry Land Asia is the largest arid and semi-arid region in the northern hemisphere that suffers from land desertification. Over the period 1982–2011, there were both overall improvement and regional degeneration in the vegetation NDVI. We analyze future climate changes in these area using two ensemble-average methods from CMIP5 data. Bayesian Model Averaging shows a better capability to represen...

The Neogene eolian deposits in the Chinese Loess Plateau (CLP) are one of the most useful continental deposits for understanding climatic changes. To decipher Late Neogene paleoclimatic changes in the CLP, we present a terrestrial mollusk record spanning the time interval between 7.1 and 3.5 Ma from the western CLP. The results indicate four stages of paleoclimatic evolution: From 7.1 to 6.2 Ma...

Introduction: This study is aimed at analyzing farmers’ perception and adaptation to climate change in the Dabus watershed. It is based on analysis of data collected from 734 randomly selected farm householdheads substantiated with Focus Group Discussions and field observations. Methods: The study employed descriptive methods to assess farmers’ perception of climate change, localindicators of c...

Climate change during the last millennium is simulated using fully coupled three-dimensional model CCSM 2.0.1. The model is driven by the natural and anthropogenic forcings. Simulated temperatures over the whole of China and over the Eastern part of China, from combined forcing correlate to some extend with the proxy data, while simulated precipitation in East China (East of 105 E, 25–40 N) and...

The upper kilometer of the Hawaiian Scientific Drilling Program core consists of lavas that were emplaced subaerially, burying paleosols. These paleosols were preserved with minimal alteration and are used to construct a ∼330-kyr Quaternary climate record. Within the temporal resolution of this record, there appears to be a ∼100-kyr climate oscillation between cool-dry and warm-wet conditions, ...

From 60 decade  sustainability issues  and sustainable developing  have opened a way in scientific meetings associated with  environment and urbanization and architecture. Sustainability goals are improving of environment situation , less pollution  and at least interference on  land and interaction of  natural and artificial environment , that most of these cases attracted attention in archite...

Fires burning the vast grasslands and savannas of Africa significantly influence the global carbon cycle. Projecting the impacts of future climate change on fire-mediated biogeochemical processes in these dry tropical ecosystems requires understanding of how various climate factors influence regional fire regimes. To examine climate-vegetation-fire linkages in dry savanna, we conducted macrosco...
