Grass pea (Lathyrus sativus L.) is probably the most drought tolerant legume crop and it is also resistant to moderate salinity. In drought prone areas the plant is considered an insurance crop for subsistence farmers. During drought-triggered famines, grass pea can be the only food available and a lifesaver. In addition, grass pea is valuable for its abundant nutrients, especially protein and ...

Real-time information on the development of the drought conditions is one of the fundamental requisites for reinforcing the drought mitigation and preparedness. The EuroGEOSS interoperability approach promotes the development of monitoring and early warning systems based on real-time information. Different climatic databases, which are based on publicly available meteorological information, are...

Observed alternation of global and local meteorological patterns governs increasing drought impact, which puts at risk ecological balance and biodiversity of the alpine forest. Despite considerable attention, drought impact on forest ecosystems is still not entirely understood, and comprehensive forest drought monitoring has not been implemented. In this study, we proposed to bridge this gap ex...

in this study, we used monthly palmer severity drought index (pdsi) data of national center of oceanic atmospheric administration (noaa) during 1/1950 to 12/2005(56 year). the time and space resolution of data is monthly and 2.5*2.5 degree respectively. therefore 26 pixels located in iran political boundary. a matrix 26*672 carried out that pixels located on rows and month located on column. th...

A field experiment was conducted during 2001-2003 to evaluate the effect of water stress on the yield and yield components of four rice cultivars commonly grown in Mazandaran province, Iran. In northern Iran irrigated lowland rice usually experiences water deficit during the growing season include of land preparation time, planting, tillering stage, flowering and grain filing period. Recently d...

Hydrological drought analysis using SDI index in Halilrud basin of Iran Abstract Nowadays, drought is considered as damaging environmental phenomenon which affects natural resources and social communities. Therefore it will be an important issues that magnitude and effects of these phenomena to be considered. To do this we used L-moment method for regional homogeneity testing. The Streamflow Dr...

Importance of pond based carp polyculture as a popular technique for fish production in Bangladesh is well documented [1]. It has further potentials to improve the livelihood of the poor and marginal peoples [2]. Potentials of pond based fish production towards livelihood improvement are also explored well by Hossain et al. [3] for Barind area having characteristic soil-water qualities like low...

The Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation (GPM) are the most important widely used data sources in several applications—e.g., forecasting drought flood, managing water resources—especially areas with sparse or no other robust sources. This study explored accuracy precision of satellite products over a span 18 years (2000–2017) using synoptic ground station for thre...
