Drought is a natural disaster. Because a significant impact on the agricultural and economy sector, it affects the lives of local residents. With Using of the remote sensing, drought can be studied through its effects on plants and agriculture resulting in more accurate and effective results found for modeling drought. In this study, the efficiency of agricultural drought indicators for estimat...

As weather patterns become more volatile and extreme, risks introduced by weather variability will become more critical to agricultural production. The availability of days suitable for field work is driven by soil temperature and moisture, both of which may be altered by climate change. We projected changes in Illinois season length, spring field workability, and summer drought risk under thre...

The dynamics of local climates make development of agricultural strategies challenging. Yield improvement has progressed slowly, especially in drought-prone regions where annual crop production suffers from episodic aridity. Underlying drought responses are circadian and diel control of gene expression that regulate daily variations in metabolic and physiological pathways. To identify transcrip...

Abstract Drought is projected to become more frequent and increasingly severe under climate change in many agriculturally important areas. However, few studies have assessed mapped the future global crop drought risk—defined as occurrence probability likelihood of yield losses from drought—at high resolution. With support GEPIC-Vulnerability-Risk model, we propose an analytical framework quanti...

Abstract Agricultural drought risk assessment is helpful in quantitatively understanding agricultural and scientifically guiding disaster prevention mitigation. Therefore, according to the characteristics of attribute uncertainty index weight subjectivity assessment, an interval identification model combined with grey relational analysis was established evaluate risk. Firstly, evaluation system...

Woody crops such as poplars (Populus) can contribute to meet the increasing energy demand of a growing human population and can therefore enhance the security of energy supply. Using energy from biomass increases ecological sustainability as biomass is considered to play a pivotal role in abating climate change. Because areas for establishing poplar plantations are often confined to marginal si...

When I request a memory from 2012 to dairy farmers, almost unanimously they respond “drought stress.” According to the US Department of Agriculture (USDA, 2013), the spring and summer drought of 2012 will be remembered as one of the “worst agricultural calamities” in the United States (USDA, 2013). The drought of 2012 reduced the national corn grain and silage yields by 16.2 and 16.3%, respecti...

120 Journal of Plant Registrations, Vol 2, No. 2, May 2008 Drought stress reduces dry bean seed yield in most production regions worldwide (White and Singh, 1991). The release of pinto bean (Phaseolus vulgaris L.) germplasm CO46348 (Reg. No. GP-275, PI 651500) will provide plant breeders with drought-tolerant, pinto bean germplasm that takes advantage of a full growing season (95–98 d) and has ...

Drought and salinity are major factors limiting agriculture in many regions in the world, and their importance is predicted to even increase in the near future in parallel with the ongoing global warming and climate changes. Soil and rhizosphere microbes are potential resources for counteracting such abiotic stresses in plants. The knowledge on the roles of root microorganisms in retaining soil...
