This study evaluates new multi-scale, multi-indicator methods for assessing the vulnerability of crop production to drought at a national and regional scale by identifying differences across and within ten regions of Ghana, a country that faces many climate and crop production challenges typical of subSaharan Africa. We highlight key methodological steps required to improve drought sensitivity ...

isotope data from bulk carbonates, micrite, marine calcite cements, non-skeletal grains and brachiopods indicate deposition of a wide spectrum of warm to cold water carbonates during the ordovician and the jurassic. this isotopic interpretation is supported by warm to cold climatic models proposed for the ordovician and the jurassic. these carbonates formed during the greenhouse mode (condition...

the rehabilitation of sandy desertified land in various dryland ecosystems by different management practices has a great potential to increase aggregate stability and improve soil quality. however, plants in general may have a different ability to sustain soil. the objective was to determine the effects of reclamation practices including haloxylon ammodendron and atriplex canescens plantation o...

an agroecological zones (aez) map is an essential tool for agricultural planning. by integrating the key components of the agricultural environments, it offers a bird's-eye view of internal diversity, agricultural potential and constraints that decision-makers find easier to understand than a pile of single-theme maps. in this study, aez map of the karkheh river basin has been prepared usi...

• Coldness and dry air drive contrasting WUE responses to dryness (EF) via GEP changes. Greater impact from than ET on meadow under high soil moisture. T/ET had logarithmic relation with LAI, negative linear dryness. The future climate change predicts higher drought risks in deteriorating the functions services of dryland ecosystems. Interpreting sensitivity ecosystem water use efficiency (WUE)...

INTRODUCTION Presently, it is difficult to predict which patients are at increased risk of ongoing pain problems postoperatively. This study followed a group of patients from the week before their operation until 3 months after it, to identify potential risk variables. METHODS Fifty-four patients undergoing moderate-major gynaecological surgery at Christchurch Women's Hospital were recruited ...

The Tibetan Plateau is a key area for research on global environmental changes. During the past 50 years, the climate in the Siling Co lake area has become continuously warmer and wetter, which may have further caused the increase in Siling Co lake area. Based on the Siling Co lake area (2003 to 2013) and climate data acquired from the Xainza and Baingoin meteorological stations (covering 1966 ...
