Studies of rainfall variation generally focus on large areas. For example, in India, the area average monsoon rainfall series of the whole country or meteorological subdivisions are used. This would be of no use for local agriculture, particularly in places where rainfall is very high or very low, especially for crops like small cardamom and vanilla which are very sensitive to soil moisture and...

iran is one of the most important centers of diversity for onobrychismill. genus. onobrychis species collected from different habitates of kermanshah province during 2010-2012 were evaluated and the relationship among their eco-geographical distribution, geographical and ecological characteristics was analyzed using arcgis.  the results showed that most of the species of onobrychis grow in the ...

Abstract The impacts of climate change and human activities on vegetation dynamics have attracted wide attention, especially in sensitive vulnerable areas such as the Qingzang Plateau China. In this region, a series ecological restoration projects been launched while effectiveness these requires evaluation further improvements. Remote sensing with high temporal resolution spatial coverage is an...

Heat stress during flowering is a critical limitation for summer maize production. However, the incidence of heat varies with years and locations, it poses great risk to successful reproduction kernel setting. Therefore, essential provide sound quantification occurrence in relation growth development. Here, we analyzed characteristics based on climate data over 60 Huaibei Plain, China. The effe...

Agricultural drought, a common phenomenon in most parts of the world, is one of the most challenging natural hazards to monitor effectively. Land surface water index (LSWI), calculated as a normalized ratio between near infrared (NIR) and short-wave infrared (SWIR), is sensitive to vegetation and soil water content. This study examined the potential of a LSWI-based, drought-monitoring algorithm...

In northern China, precipitation fluctuates greatly and drought occurs frequently, which mark some of the important threats to agricultural animal husbandry production. Understanding meteorological dry-wet change evolution law events in China has guiding significance for regional disaster prevention mitigation. Based on standardized index (SPI), this paper explored spatio-temporal China. Our re...

Evaporation from surface water plays a crucial role in accounting of basins, resource management, and irrigation systems management. As such, the simulation evaporation with high accuracy is very important. In this study, two methods for simulating pan under different climatic conditions Iran were developed. first method, six experimental relationships (linear, quadratic, cubic, input combinati...
